sayantann11 / All Classification Templetes For MLClassification - Machine Learning This is ‘Classification’ tutorial which is a part of the Machine Learning course offered by Simplilearn. We will learn Classification algorithms, types of classification algorithms, support vector machines(SVM), Naive Bayes, Decision Tree and Random Forest Classifier in this tutorial. Objectives Let us look at some of the objectives covered under this section of Machine Learning tutorial. Define Classification and list its algorithms Describe Logistic Regression and Sigmoid Probability Explain K-Nearest Neighbors and KNN classification Understand Support Vector Machines, Polynomial Kernel, and Kernel Trick Analyze Kernel Support Vector Machines with an example Implement the Naïve Bayes Classifier Demonstrate Decision Tree Classifier Describe Random Forest Classifier Classification: Meaning Classification is a type of supervised learning. It specifies the class to which data elements belong to and is best used when the output has finite and discrete values. It predicts a class for an input variable as well. There are 2 types of Classification: Binomial Multi-Class Classification: Use Cases Some of the key areas where classification cases are being used: To find whether an email received is a spam or ham To identify customer segments To find if a bank loan is granted To identify if a kid will pass or fail in an examination Classification: Example Social media sentiment analysis has two potential outcomes, positive or negative, as displayed by the chart given below. https://www.simplilearn.com/ice9/free_resources_article_thumb/classification-example-machine-learning.JPG This chart shows the classification of the Iris flower dataset into its three sub-species indicated by codes 0, 1, and 2. https://www.simplilearn.com/ice9/free_resources_article_thumb/iris-flower-dataset-graph.JPG The test set dots represent the assignment of new test data points to one class or the other based on the trained classifier model. Types of Classification Algorithms Let’s have a quick look into the types of Classification Algorithm below. Linear Models Logistic Regression Support Vector Machines Nonlinear models K-nearest Neighbors (KNN) Kernel Support Vector Machines (SVM) Naïve Bayes Decision Tree Classification Random Forest Classification Logistic Regression: Meaning Let us understand the Logistic Regression model below. This refers to a regression model that is used for classification. This method is widely used for binary classification problems. It can also be extended to multi-class classification problems. Here, the dependent variable is categorical: y ϵ {0, 1} A binary dependent variable can have only two values, like 0 or 1, win or lose, pass or fail, healthy or sick, etc In this case, you model the probability distribution of output y as 1 or 0. This is called the sigmoid probability (σ). If σ(θ Tx) > 0.5, set y = 1, else set y = 0 Unlike Linear Regression (and its Normal Equation solution), there is no closed form solution for finding optimal weights of Logistic Regression. Instead, you must solve this with maximum likelihood estimation (a probability model to detect the maximum likelihood of something happening). It can be used to calculate the probability of a given outcome in a binary model, like the probability of being classified as sick or passing an exam. https://www.simplilearn.com/ice9/free_resources_article_thumb/logistic-regression-example-graph.JPG Sigmoid Probability The probability in the logistic regression is often represented by the Sigmoid function (also called the logistic function or the S-curve): https://www.simplilearn.com/ice9/free_resources_article_thumb/sigmoid-function-machine-learning.JPG In this equation, t represents data values * the number of hours studied and S(t) represents the probability of passing the exam. Assume sigmoid function: https://www.simplilearn.com/ice9/free_resources_article_thumb/sigmoid-probability-machine-learning.JPG g(z) tends toward 1 as z -> infinity , and g(z) tends toward 0 as z -> infinity K-nearest Neighbors (KNN) K-nearest Neighbors algorithm is used to assign a data point to clusters based on similarity measurement. It uses a supervised method for classification. The steps to writing a k-means algorithm are as given below: https://www.simplilearn.com/ice9/free_resources_article_thumb/knn-distribution-graph-machine-learning.JPG Choose the number of k and a distance metric. (k = 5 is common) Find k-nearest neighbors of the sample that you want to classify Assign the class label by majority vote. KNN Classification A new input point is classified in the category such that it has the most number of neighbors from that category. For example: https://www.simplilearn.com/ice9/free_resources_article_thumb/knn-classification-machine-learning.JPG Classify a patient as high risk or low risk. Mark email as spam or ham. Keen on learning about Classification Algorithms in Machine Learning? Click here! Support Vector Machine (SVM) Let us understand Support Vector Machine (SVM) in detail below. SVMs are classification algorithms used to assign data to various classes. They involve detecting hyperplanes which segregate data into classes. SVMs are very versatile and are also capable of performing linear or nonlinear classification, regression, and outlier detection. Once ideal hyperplanes are discovered, new data points can be easily classified. https://www.simplilearn.com/ice9/free_resources_article_thumb/support-vector-machines-graph-machine-learning.JPG The optimization objective is to find “maximum margin hyperplane” that is farthest from the closest points in the two classes (these points are called support vectors). In the given figure, the middle line represents the hyperplane. SVM Example Let’s look at this image below and have an idea about SVM in general. Hyperplanes with larger margins have lower generalization error. The positive and negative hyperplanes are represented by: https://www.simplilearn.com/ice9/free_resources_article_thumb/positive-negative-hyperplanes-machine-learning.JPG Classification of any new input sample xtest : If w0 + wTxtest > 1, the sample xtest is said to be in the class toward the right of the positive hyperplane. If w0 + wTxtest < -1, the sample xtest is said to be in the class toward the left of the negative hyperplane. When you subtract the two equations, you get: https://www.simplilearn.com/ice9/free_resources_article_thumb/equation-subtraction-machine-learning.JPG Length of vector w is (L2 norm length): https://www.simplilearn.com/ice9/free_resources_article_thumb/length-of-vector-machine-learning.JPG You normalize with the length of w to arrive at: https://www.simplilearn.com/ice9/free_resources_article_thumb/normalize-equation-machine-learning.JPG SVM: Hard Margin Classification Given below are some points to understand Hard Margin Classification. The left side of equation SVM-1 given above can be interpreted as the distance between the positive (+ve) and negative (-ve) hyperplanes; in other words, it is the margin that can be maximized. Hence the objective of the function is to maximize with the constraint that the samples are classified correctly, which is represented as : https://www.simplilearn.com/ice9/free_resources_article_thumb/hard-margin-classification-machine-learning.JPG This means that you are minimizing ‖w‖. This also means that all positive samples are on one side of the positive hyperplane and all negative samples are on the other side of the negative hyperplane. This can be written concisely as : https://www.simplilearn.com/ice9/free_resources_article_thumb/hard-margin-classification-formula.JPG Minimizing ‖w‖ is the same as minimizing. This figure is better as it is differentiable even at w = 0. The approach listed above is called “hard margin linear SVM classifier.” SVM: Soft Margin Classification Given below are some points to understand Soft Margin Classification. To allow for linear constraints to be relaxed for nonlinearly separable data, a slack variable is introduced. (i) measures how much ith instance is allowed to violate the margin. The slack variable is simply added to the linear constraints. https://www.simplilearn.com/ice9/free_resources_article_thumb/soft-margin-calculation-machine-learning.JPG Subject to the above constraints, the new objective to be minimized becomes: https://www.simplilearn.com/ice9/free_resources_article_thumb/soft-margin-calculation-formula.JPG You have two conflicting objectives now—minimizing slack variable to reduce margin violations and minimizing to increase the margin. The hyperparameter C allows us to define this trade-off. Large values of C correspond to larger error penalties (so smaller margins), whereas smaller values of C allow for higher misclassification errors and larger margins. https://www.simplilearn.com/ice9/free_resources_article_thumb/machine-learning-certification-video-preview.jpg SVM: Regularization The concept of C is the reverse of regularization. Higher C means lower regularization, which increases bias and lowers the variance (causing overfitting). https://www.simplilearn.com/ice9/free_resources_article_thumb/concept-of-c-graph-machine-learning.JPG IRIS Data Set The Iris dataset contains measurements of 150 IRIS flowers from three different species: Setosa Versicolor Viriginica Each row represents one sample. Flower measurements in centimeters are stored as columns. These are called features. IRIS Data Set: SVM Let’s train an SVM model using sci-kit-learn for the Iris dataset: https://www.simplilearn.com/ice9/free_resources_article_thumb/svm-model-graph-machine-learning.JPG Nonlinear SVM Classification There are two ways to solve nonlinear SVMs: by adding polynomial features by adding similarity features Polynomial features can be added to datasets; in some cases, this can create a linearly separable dataset. https://www.simplilearn.com/ice9/free_resources_article_thumb/nonlinear-classification-svm-machine-learning.JPG In the figure on the left, there is only 1 feature x1. This dataset is not linearly separable. If you add x2 = (x1)2 (figure on the right), the data becomes linearly separable. Polynomial Kernel In sci-kit-learn, one can use a Pipeline class for creating polynomial features. Classification results for the Moons dataset are shown in the figure. https://www.simplilearn.com/ice9/free_resources_article_thumb/polynomial-kernel-machine-learning.JPG Polynomial Kernel with Kernel Trick Let us look at the image below and understand Kernel Trick in detail. https://www.simplilearn.com/ice9/free_resources_article_thumb/polynomial-kernel-with-kernel-trick.JPG For large dimensional datasets, adding too many polynomial features can slow down the model. You can apply a kernel trick with the effect of polynomial features without actually adding them. The code is shown (SVC class) below trains an SVM classifier using a 3rd-degree polynomial kernel but with a kernel trick. https://www.simplilearn.com/ice9/free_resources_article_thumb/polynomial-kernel-equation-machine-learning.JPG The hyperparameter coefθ controls the influence of high-degree polynomials. Kernel SVM Let us understand in detail about Kernel SVM. Kernel SVMs are used for classification of nonlinear data. In the chart, nonlinear data is projected into a higher dimensional space via a mapping function where it becomes linearly separable. https://www.simplilearn.com/ice9/free_resources_article_thumb/kernel-svm-machine-learning.JPG In the higher dimension, a linear separating hyperplane can be derived and used for classification. A reverse projection of the higher dimension back to original feature space takes it back to nonlinear shape. As mentioned previously, SVMs can be kernelized to solve nonlinear classification problems. You can create a sample dataset for XOR gate (nonlinear problem) from NumPy. 100 samples will be assigned the class sample 1, and 100 samples will be assigned the class label -1. https://www.simplilearn.com/ice9/free_resources_article_thumb/kernel-svm-graph-machine-learning.JPG As you can see, this data is not linearly separable. https://www.simplilearn.com/ice9/free_resources_article_thumb/kernel-svm-non-separable.JPG You now use the kernel trick to classify XOR dataset created earlier. https://www.simplilearn.com/ice9/free_resources_article_thumb/kernel-svm-xor-machine-learning.JPG Naïve Bayes Classifier What is Naive Bayes Classifier? Have you ever wondered how your mail provider implements spam filtering or how online news channels perform news text classification or even how companies perform sentiment analysis of their audience on social media? All of this and more are done through a machine learning algorithm called Naive Bayes Classifier. Naive Bayes Named after Thomas Bayes from the 1700s who first coined this in the Western literature. Naive Bayes classifier works on the principle of conditional probability as given by the Bayes theorem. Advantages of Naive Bayes Classifier Listed below are six benefits of Naive Bayes Classifier. Very simple and easy to implement Needs less training data Handles both continuous and discrete data Highly scalable with the number of predictors and data points As it is fast, it can be used in real-time predictions Not sensitive to irrelevant features Bayes Theorem We will understand Bayes Theorem in detail from the points mentioned below. According to the Bayes model, the conditional probability P(Y|X) can be calculated as: P(Y|X) = P(X|Y)P(Y) / P(X) This means you have to estimate a very large number of P(X|Y) probabilities for a relatively small vector space X. For example, for a Boolean Y and 30 possible Boolean attributes in the X vector, you will have to estimate 3 billion probabilities P(X|Y). To make it practical, a Naïve Bayes classifier is used, which assumes conditional independence of P(X) to each other, with a given value of Y. This reduces the number of probability estimates to 2*30=60 in the above example. Naïve Bayes Classifier for SMS Spam Detection Consider a labeled SMS database having 5574 messages. It has messages as given below: https://www.simplilearn.com/ice9/free_resources_article_thumb/naive-bayes-spam-machine-learning.JPG Each message is marked as spam or ham in the data set. Let’s train a model with Naïve Bayes algorithm to detect spam from ham. The message lengths and their frequency (in the training dataset) are as shown below: https://www.simplilearn.com/ice9/free_resources_article_thumb/naive-bayes-spam-spam-detection.JPG Analyze the logic you use to train an algorithm to detect spam: Split each message into individual words/tokens (bag of words). Lemmatize the data (each word takes its base form, like “walking” or “walked” is replaced with “walk”). Convert data to vectors using scikit-learn module CountVectorizer. Run TFIDF to remove common words like “is,” “are,” “and.” Now apply scikit-learn module for Naïve Bayes MultinomialNB to get the Spam Detector. This spam detector can then be used to classify a random new message as spam or ham. Next, the accuracy of the spam detector is checked using the Confusion Matrix. For the SMS spam example above, the confusion matrix is shown on the right. Accuracy Rate = Correct / Total = (4827 + 592)/5574 = 97.21% Error Rate = Wrong / Total = (155 + 0)/5574 = 2.78% https://www.simplilearn.com/ice9/free_resources_article_thumb/confusion-matrix-machine-learning.JPG Although confusion Matrix is useful, some more precise metrics are provided by Precision and Recall. https://www.simplilearn.com/ice9/free_resources_article_thumb/precision-recall-matrix-machine-learning.JPG Precision refers to the accuracy of positive predictions. https://www.simplilearn.com/ice9/free_resources_article_thumb/precision-formula-machine-learning.JPG Recall refers to the ratio of positive instances that are correctly detected by the classifier (also known as True positive rate or TPR). https://www.simplilearn.com/ice9/free_resources_article_thumb/recall-formula-machine-learning.JPG Precision/Recall Trade-off To detect age-appropriate videos for kids, you need high precision (low recall) to ensure that only safe videos make the cut (even though a few safe videos may be left out). The high recall is needed (low precision is acceptable) in-store surveillance to catch shoplifters; a few false alarms are acceptable, but all shoplifters must be caught. Learn about Naive Bayes in detail. Click here! Decision Tree Classifier Some aspects of the Decision Tree Classifier mentioned below are. Decision Trees (DT) can be used both for classification and regression. The advantage of decision trees is that they require very little data preparation. They do not require feature scaling or centering at all. They are also the fundamental components of Random Forests, one of the most powerful ML algorithms. Unlike Random Forests and Neural Networks (which do black-box modeling), Decision Trees are white box models, which means that inner workings of these models are clearly understood. In the case of classification, the data is segregated based on a series of questions. Any new data point is assigned to the selected leaf node. https://www.simplilearn.com/ice9/free_resources_article_thumb/decision-tree-classifier-machine-learning.JPG Start at the tree root and split the data on the feature using the decision algorithm, resulting in the largest information gain (IG). This splitting procedure is then repeated in an iterative process at each child node until the leaves are pure. This means that the samples at each node belonging to the same class. In practice, you can set a limit on the depth of the tree to prevent overfitting. The purity is compromised here as the final leaves may still have some impurity. The figure shows the classification of the Iris dataset. https://www.simplilearn.com/ice9/free_resources_article_thumb/decision-tree-classifier-graph.JPG IRIS Decision Tree Let’s build a Decision Tree using scikit-learn for the Iris flower dataset and also visualize it using export_graphviz API. https://www.simplilearn.com/ice9/free_resources_article_thumb/iris-decision-tree-machine-learning.JPG The output of export_graphviz can be converted into png format: https://www.simplilearn.com/ice9/free_resources_article_thumb/iris-decision-tree-output.JPG Sample attribute stands for the number of training instances the node applies to. Value attribute stands for the number of training instances of each class the node applies to. Gini impurity measures the node’s impurity. A node is “pure” (gini=0) if all training instances it applies to belong to the same class. https://www.simplilearn.com/ice9/free_resources_article_thumb/impurity-formula-machine-learning.JPG For example, for Versicolor (green color node), the Gini is 1-(0/54)2 -(49/54)2 -(5/54) 2 ≈ 0.168 https://www.simplilearn.com/ice9/free_resources_article_thumb/iris-decision-tree-sample.JPG Decision Boundaries Let us learn to create decision boundaries below. For the first node (depth 0), the solid line splits the data (Iris-Setosa on left). Gini is 0 for Setosa node, so no further split is possible. The second node (depth 1) splits the data into Versicolor and Virginica. If max_depth were set as 3, a third split would happen (vertical dotted line). https://www.simplilearn.com/ice9/free_resources_article_thumb/decision-tree-boundaries.JPG For a sample with petal length 5 cm and petal width 1.5 cm, the tree traverses to depth 2 left node, so the probability predictions for this sample are 0% for Iris-Setosa (0/54), 90.7% for Iris-Versicolor (49/54), and 9.3% for Iris-Virginica (5/54) CART Training Algorithm Scikit-learn uses Classification and Regression Trees (CART) algorithm to train Decision Trees. CART algorithm: Split the data into two subsets using a single feature k and threshold tk (example, petal length < “2.45 cm”). This is done recursively for each node. k and tk are chosen such that they produce the purest subsets (weighted by their size). The objective is to minimize the cost function as given below: https://www.simplilearn.com/ice9/free_resources_article_thumb/cart-training-algorithm-machine-learning.JPG The algorithm stops executing if one of the following situations occurs: max_depth is reached No further splits are found for each node Other hyperparameters may be used to stop the tree: min_samples_split min_samples_leaf min_weight_fraction_leaf max_leaf_nodes Gini Impurity or Entropy Entropy is one more measure of impurity and can be used in place of Gini. https://www.simplilearn.com/ice9/free_resources_article_thumb/gini-impurity-entrophy.JPG It is a degree of uncertainty, and Information Gain is the reduction that occurs in entropy as one traverses down the tree. Entropy is zero for a DT node when the node contains instances of only one class. Entropy for depth 2 left node in the example given above is: https://www.simplilearn.com/ice9/free_resources_article_thumb/entrophy-for-depth-2.JPG Gini and Entropy both lead to similar trees. DT: Regularization The following figure shows two decision trees on the moons dataset. https://www.simplilearn.com/ice9/free_resources_article_thumb/dt-regularization-machine-learning.JPG The decision tree on the right is restricted by min_samples_leaf = 4. The model on the left is overfitting, while the model on the right generalizes better. Random Forest Classifier Let us have an understanding of Random Forest Classifier below. A random forest can be considered an ensemble of decision trees (Ensemble learning). Random Forest algorithm: Draw a random bootstrap sample of size n (randomly choose n samples from the training set). Grow a decision tree from the bootstrap sample. At each node, randomly select d features. Split the node using the feature that provides the best split according to the objective function, for instance by maximizing the information gain. Repeat the steps 1 to 2 k times. (k is the number of trees you want to create, using a subset of samples) Aggregate the prediction by each tree for a new data point to assign the class label by majority vote (pick the group selected by the most number of trees and assign new data point to that group). Random Forests are opaque, which means it is difficult to visualize their inner workings. https://www.simplilearn.com/ice9/free_resources_article_thumb/random-forest-classifier-graph.JPG However, the advantages outweigh their limitations since you do not have to worry about hyperparameters except k, which stands for the number of decision trees to be created from a subset of samples. RF is quite robust to noise from the individual decision trees. Hence, you need not prune individual decision trees. The larger the number of decision trees, the more accurate the Random Forest prediction is. (This, however, comes with higher computation cost). Key Takeaways Let us quickly run through what we have learned so far in this Classification tutorial. Classification algorithms are supervised learning methods to split data into classes. They can work on Linear Data as well as Nonlinear Data. Logistic Regression can classify data based on weighted parameters and sigmoid conversion to calculate the probability of classes. K-nearest Neighbors (KNN) algorithm uses similar features to classify data. Support Vector Machines (SVMs) classify data by detecting the maximum margin hyperplane between data classes. Naïve Bayes, a simplified Bayes Model, can help classify data using conditional probability models. Decision Trees are powerful classifiers and use tree splitting logic until pure or somewhat pure leaf node classes are attained. Random Forests apply Ensemble Learning to Decision Trees for more accurate classification predictions. Conclusion This completes ‘Classification’ tutorial. In the next tutorial, we will learn 'Unsupervised Learning with Clustering.'
rprokap / Pset 9CREDITS SEQUENCE NEWSPAPER HEADLINE MONTAGE: HEADLINES flash before us, displaying their accompanying photographs. "UBERMAN - METRO CITY'S HERO AFTER DEFEATING MASTER MIND! PHOTO: A chiseled, statuesque man wearing the COOLEST SUPER HERO SUIT IMAGINABLE, COMPLETE WITH FLOWING CAPE, shines a confident smile at the lens. This is UBERMAN, champion of METRO CITY. "UBERMAN DEFEATS MASTER MIND'S GIANT ROBOT!" PHOTO: Wide-shot of Uberman in mid-flight lifting the GIANT ROBOT in the sky above the city buildings. "MASTER MIND ALL WET AFTER UBERMAN FOILS AQUARIUM HEIST!" PHOTO: Uberman stands knee-deep in water. He has his enemy by the collar. The villain blocks his face from the shot with a METALLIC GAUNTLET. The images start to flash by even quicker, each showing the MYSTERIOUS VILLAIN in various stages of humiliation. In each photograph he successfully blocks his face with his armored glove. We ZOOM IN to the last headline. "MASTER MIND BEHIND BARS ONCE AGAIN - THANKS TO UBERMAN!" PHOTO: Uberman stands in a gallant pose with his fists on his hips, obviously trying to accentuate the "U" insignia on his chest. END OF CREDITS SEQUENCE EXT. BUILDING - DAY We DISSOLVE from the photograph to Uberman standing in the exact same position. WE PULL BACK showing him atop a BUILDING overlooking the city below. A perfect view for our guardian hero. He watches the thriving metropolis, bristling with life as people happily go about their day. Yet, we can't help but detect a hint of sadness in Uberman's expression. 2. UBERMAN You look so peaceful from up here. His serenity is suddenly interrupted by a loud BEEPING SOUND coming from his wrist. He looks down at a BRACELET (a manly one) on his right arm. It's a silver band with a FLASHING red letter "U". UBERMAN (CONT'D) Looks like Roxanne's in trouble again. Uberman leaps off the building and into the air. His cape gracefully flows in the breeze behind him as he shoots off into the distance like a speeding bullet. EXT. OBSERVATORY HIDEOUT - ESTABLISHING SHOT Grime and moss decorate the outside of this long abandoned building overlooking the COAST. Once a place of knowledge and wonder - now home to a great evil. INT. OBSERVATORY HIDEOUT - DAY The inside is in complete contrast to the exterior. The huge hall with a GIANT TELESCOPE teems with advanced ELECTRONIC EQUIPMENT. Computers, monitors and machines which do not have an obvious function FLASH and HUM. A STEEL DOOR slides open, revealing the subject of our story MASTER MIND - a villainous sight to behold. His FACE IS INEXPLICABLY LIGHT BLUE, topped by an OVERSIZED, MUSHROOM- SHAPED HEAD with a CIRCULAR PATCH OF WHITE HAIR ON TOP. He's dressed in the kind of costume only a super villain could pull off: a PURPLE JUMPSUIT AND BLACK BOOT ENSEMBLE WITH A GIANT GREEN "M" ON THE CHEST. His right hand, hanging at his side, is a METAL GAUNTLET WITH THREE SHORT SPIKES PROTRUDING BETWEEN HIS KNUCKLES. Master Mind begins to survey the room with his TWO PERMANENTLY ARCHED EYEBROWS. A man dressed as ALBERT EINSTEIN is busy ranting to two other men. One, a hulking brute, is dressed as LEONARDO DA VINCI. The other, a small intellectual-type carrying a clip-board, is dressed as the philosopher PLATO. EINSTEIN I hate the outfits. I mean, I get it: we're all supposed to be "masterminds" - very clever. (MORE) 3. EINSTEIN(cont'd) I just feel stupid. I mean, what the hell did Einstein really do anyway? PLATO Theory of relativity. Einstein starts feverishly scratching his side. EINSTEIN Well, you'd think he'd invent a wool sweater that didn't itch so much. Da Vinci and Plato's eyes suddenly grow with concern as they see Master Mind walk up behind Einstein. Einstein notices his colleague's staring over his right shoulder and turns around. He turns around and Master Mind SEIZES HIM BY HIS THROAT with his metal gauntlet. MASTER MIND The real Einstein once said, "God does not play dice with the world." He was right, because the world is MY dice. Is that understood? DA VINCI & PLATO Sir! Yes, sir! EINSTEIN (gasping for air) Yes, sir. Master Mind undoes his grip on Einstein's throat. MASTER MIND Alright, then - clean slate. Do we have the girl? DA VINCI Yes, sir. She fell into our trap just like you knew she would. MASTER MIND Reporters are a curious lot, and easily manipulated. He quickly checks his physique in a GIANT MIRROR, adjusts his posture and sucks in his gut. 4. MASTER MIND Alright, let's not keep the lady waiting. MOMENTS LATER Da Vinci escorts a BLINDFOLDED and bound woman, ROXANNE RITCHI, to the back of the room where Plato and Einstein are standing guard over a large BLACK SWIVEL-CHAIR facing away from us. She pulls free of Da Vinci's grasp and waits for him to undo the blindfold. Her face uncovered, we finally see Roxanne's striking features - all of which seem overshadowed by piercing eyes that seem more put off by the situation than afraid of it. MASTER MIND (O.S.) Miss Ritchi, we meet again. The chair turns menacingly slow, finally revealing Master Mind. ROXANNE You didn't need to turn around like that. I can recognize the stench of failure. Master Mind unleashes a wicked laugh. MASTER MIND I trust you gentlemen know the very sassy Roxanne Ritchi, highly regarded investigative journalist who some say has a more than friendly relationship with our super powered foe Uberman. And Miss Ritchi, I trust you've already met my new crew: The Mad Geniuses! Roxanne gives Einstein a once over. ROXANNE Looks like a real group of winners. At the risk of sounding cliche', you'll never get away with this. MASTER MIND In a way, I already have. Roxanne unleashes an exhausted SIGH. 5. ROXANNE We go through this every time. You kidnap me to get to Uberman, he immediately finds your hideout, escapes whatever lame trap you've come up with, and takes you and your cronies to jail. I propose we just save everybody some heartache this time by YOU letting me go, and ME forgetting this whole thing ever happened? MASTER MIND What about my revenge? ROXANNE We can say it was wasting everyone's time. MASTER MIND You have a wicked tongue. I hope you rid yourself of that when you're my queen. Roxanne unleashes a snort-filled laugh. ROXANNE I'm sorry. What makes you think I would want to be your queen? MASTER MIND Power corrupts absolutely, Miss Ritchi. And when I have ultimate power over this city, I have absolutely every intention of corrupting you with it. PLATO Sir! Master Mind turns to Plato who's now standing at a computer terminal. MASTER MIND (annoyed) What is it!? EXT. OBSERVATORY HIDEOUT - DAY Uberman flies toward the Observatory like a rocket. 6. INT. OBSERVATORY HIDEOUT - DAY Uberman crashes through the wall to the room we were just in. He looks around, but there's suddenly NOT A SOUL IN SIGHT. CUT TO: EXT. MASTER MIND'S HYDROFOIL - DAY The boat is shooting through the ocean, away from the observatory. INT. HYDROFOIL CONTROL ROOM - DAY Machines, cables and terminals criss-cross the craft's main bridge. Through the enormous surrounding windows we can see the observatory shrinking in the distance. Master Mind watches Uberman on a small TV monitor as the hero intently searches his hideout. UBERMAN (on monitor) Master Mind! INT. OBSERVATORY HIDEOUT - DAY Uberman throws up his arms in frustration when suddenly - MASTER MIND (O.S.) Over here, old friend. He turns to see a FAMILIAR BLUE FACE OF EVIL ON A GIANT SCREEN. UBERMAN What's the matter, miss your old jail cell? Uberman starts walking toward the monitor. MASTER MIND (ON MONITOR) Actually, I wanted to share the experience with my oldest friend. A MECHANIZED CAGE shoots out of the floor, suddenly trapping Metro City's protector. Totally unfazed, our hero stares on. 7. UBERMAN You can't possibly believe this will work. Master Mind pulls out a SMALL BLACK BOX with a SINGLE RED BUTTON on it. MASTER MIND (ON MONITOR) Oh, can't I? I have attained control of the Earth's most abundant energy source. I doubt even you are strong enough to withstand the FULL CONCENTRATED POWER OF THE SUN!!! He presses the button. EXT. OUTER SPACE A sinister-looking SATELLITE orbits Earth's atmosphere. Its bay doors suddenly open, deploying two huge SOLAR PANELS. The panels shift, angling themselves in the direction of the sun. They immediately start GLOWING as they absorb the burning star's power. The front of the satellite begins to make a loud HUMMING SOUND as it prepares to unleash its unholy power. INT. HYDROFOIL CONTROL ROOM - DAY From the giant window we can see the boat is a good mile from the observatory. PLATO We're now at minimum safe distance, master. Master Mind turns from the CAMERA he was broadcasting on and puts down the control box. MASTER MIND Excellent. Stop here, I like this view. PLATO Twenty seconds until impact. Master Mind turns to Roxanne who is being held by Da Vinci and Einstein. She almost appears a little bored. Disappointed by her lack of horror, he walks over to the monitor now showing Uberman trapped in the cage. 8. MASTER MIND Any last words? Uberman looks up at the screen with a cocky smile. UBERMAN (ON MONITOR) Yes: there's no caging the power of justice. PLATO Ten seconds to impact. On the screen we see Uberman take two of the cage's bars in his hands. He yanks...NOTHING. PLATO (CONT'D) Nine... Master Mind stares at the monitor, slightly confused. PLATO (CONT'D) Eight... Uberman yanks on the bars again, this time using his foot as leverage. MASTER MIND (genuinely concerned) What's going on? UBERMAN (straining) Hold...on...a second. Master Mind looks back at Plato and Einstein. They're equally befuddled at the hero's sudden weakness. PLATO Seven... Uberman loses his grip and FALLS BACKWARD ON HIS ASS. UBERMAN SON OF A BITCH!! Master Mind and the minions all cringe in unison. Da Vinci turns to Roxanne not believing his ears. DA VINCI What did he just say? 9. PLATO Six......Five... Master Mind begins to laugh. MASTER MIND What kind of trick is this? Uberman looks up at the camera with a very grave expression. UBERMAN Like you don't know. These bars are made of copper, aren't they? PLATO Four... MASTER MIND Yeah, so? Uberman tries to shield his grief with his hand. UBERMAN You figured out my weakness, damn you. I CAN'T BEND COPPER! PLATO Three... MASTER MIND Your weakness is copper? PLATO Two...one. Everyone turns to the window. EXT. OUTER SPACE The satellite fires a giant BEAM OF LIGHT toward the earth. EXT. OBSERVATORY HIDEOUT - DAY The beam hits the observatory. The building instantly EXPLODES in a white nova blast of fire. INT. HYDROFOIL CONTROL ROOM - DAY The blast is so bright everyone turns away from the window. Then, as suddenly as it began, the awesome light dies out. One by one, the passengers unshield their eyes and look out toward the observatory. 10. All we can see through the haze of destruction is fire and smoke. PLATO I don't think even he could have survived that. Einstein suddenly turns giddy with excitement. EINSTEIN Whoa! Is it me or did you just finally destroy Uberman? MASTER MIND (carefully skeptical) Well...let's not get ahead of ourselves. Da Vinci suddenly sees something outside. DA VINCI Look, there's something in the sky, coming this way. ROXANNE Uberman! Master Mind turns toward the window. An object is in the air, flying directly toward them. As it closes in we can just make out the FAMILIAR OUTLINE OF A CAPPED FIGURE. MASTER MIND I KNEW IT! PREPARE YOURSELVES! HE'S GONNA RAM US!!! Everyone scatters and braces themselves for the impact. Master Mind, seeing all the good places taken, doesn't know what to do with himself. He just covers his giant head with his hands. The figure CRASHES THROUGH THE WINDOW and lands at his feet. He looks down to see a CHARRED BLACK HUMAN SKELETON. Around its neck is the unmistakable black cape of Uberman. MASTER MIND (CONT'D) (horrified) HOLY SHIT! 11. Roxanne breaks out of Da Vinci's hold and runs over to the body. ROXANNE Uberman? She stares down at the still smoking corpse, the tattered black cape with the yellow "U" on it. Roxanne turns to Master Mind, who's still visibly dumbfounded at the grotesque sight before him. ROXANNE (CONT'D) You killed him! Roxanne's eyes roll back. Da Vinci catches her from behind as she FAINTS. Einstein turns to Master Mind, looking at him as if he's just walked on water. EINSTEIN You did it! Now that he's committed the impossible - our villain is at a complete loss. MASTER MIND ...so I did. EINSTEIN I mean, I know you always wanted to. I mean, all the schemes all the plots - I never thought you'd actually be capable of it. Giddy as a school girl, Einstein turns to his fellow henchmen. EINSTEIN This is history. Every villain and lackey in the history of villains and lackeys dream of this moment, but when does it actually EVER happen? A sudden realization comes over his face. EINSTEIN Good lord...You do all realize what we get to do now, don't you? 12. His question is met with acquisitive looks from Master Mind and the others. EINSTEIN We get to go on a crime wave. CRIME WAVE MONTAGE - SET TO "Fun Fun Fun" by The Beach Boys. SPINNING HEADLINE: "UBERMAN'S DEATH IGNITES CITY WIDE CRIME WAVE!" ARMORED TRUCK It's driving along when the men inside suddenly notice something - THEY'RE FLYING HIGH ABOVE THE CITY STREETS. We PULL BACK to see the truck being carried by a giant claw at the bottom of a BRAIN COPTER. Inside the cockpit Master Mind and his henchmen laugh maniacally. SPINNING HEADLINE: "CHAMPION-LESS CITY AT THE MERCY OF HOOLIGANS." METRO CITY BANK Da Vinci and Einstein run out the front of the bank holding BAGS OF MONEY. Two beat officers see them and take chase after them around the corner and into an alley. After a moment the police reemerge from the alley screaming and running for their lives as a GIANT ROBOT CHASES after them. The robot stops, then suddenly it's head opens up like convertible car top with Master Mind and Plato at the driver's wheel. They smile and shake hands at a bad deed well done. SPINNING HEADLINE: "MASTER MIND BLACKMAILS METRO!!!" A VICIOUS TORNADO It's heading for downtown Metro as Master Mind and the lackeys coolly look on. Three large DUMP TRUCKS pull up, filled to the brim with bricks of CASH. 13. The DRIVERS jump out as the lackeys take the driver seats in the three trucks. Master Mind is about to climb into the passenger seat of one when a drivers taps him on the shoulder and motions toward the tornado. MASTER MIND (absentmindedly) Oh, right. Master Mind pulls a television REMOTE from his pocket and aims it at approaching windstorm of death. He presses the button marked "Tornado Off." The tornado shrinks and disappears just before it hits the city. As they drive through the city streets, Master stares out the window with a hint of something in his eyes. Is it melancholy? END OF MONTAGE EXT. KINGPIN BOWLING - DAY It's Metro City's premier bowling alley. On top of the neon lit building is a GIANT 30 FOOT TALL CEMENT BOWLING BALL. INT. KINGPIN BOWLING - DAY HAL STEWART (early 30's) takes careful aim with his BOWLING BALL. HAL It's a sport of honor, focus and grace. Honor the ball, focus on the pins, release the ball not hard and fast, but as if you were releasing a baby dove. He takes a step, pulls back his arm, and releases the ball, following it with his eyes. It's a horrible shot - INSTANT GUTTER BALL. An aged barmaid type with a cigarette hanging from her mouth looks over at him. HAL Okay, do something like that - but center it more. 14. She picks up her custom made FOGHAT BALL and takes aim. ATTRACTIVE BLOND Tell me how my form looks, honey. Hal focuses on the misshapen bumps of her enormous Johnson administration era derriere. HAL Oh, it's lookin' good. It's lookin' REAL good. It doesn't get anymore clear. This man is a pig. VINNIE (O.S.) Hal, I want to see you in my office! Hal turns to see VINNIE, owner of the bowling alley, calling him. VINNIE Now! INT. KINGPIN BOWLING - VINNIE'S OFFICE - MOMENTS LATER Hal sits down, facing Vinnie who's sitting at his desk. VINNIE You're fired. Leave your shirt and locker key. This bit of news hits Hal like a freight train. HAL Fired? Are you going to tell me why? VINNIE Showing up to work late. Showing up to work late drunk. Sexually harassing customers. Stealing from the register. HAL Vinnie, I don't know where you're getting these accusations - Vinnie takes out a video tape from his desk drawer and puts in a VCR. 15. HAL Oh, which one do you supposedly have here? VINNIE This is all of them at once. TELEVISION A WOMAN walks up to a BOWLING EMPLOYEE and hands him a pair of shoes. As the employee turns to the wall of shoes, a very drunk and disheveled Hal comes running in and pushes him aside. HAL I've got this one, Benny. So, Cinderella. Can I help you find your glass slipper? WOMAN Yeah, I'm looking for a seven. He folds his arms on the counter and leans into her with a cat-like grin on his face. HAL (with a leer) Seven - Well, maybe I could interest you in something in an EIGHT. Namely, me. Disgusted, she walks off screen. HAL Lesbo. Suddenly realizing the register's open, he quickly grabs a stack of cash and shoves it in his pocket. BACK TO OFFICE Vinnie turns off the television and waits for Hal to respond. HAL From the angle of the camera, I can see where you might have gotten the wrong idea. Listen, Vinnie, I don't think you've thought this through. If you fire me, who's gonna be captain of the alley's bowling team? 16. VINNIE Um, I don't know. Maybe somebody who can actually bowl. You guys have never won a game. I hired you because you said you were on the pro circuit. HAL No, I said I WILL BE on the pro circuit. VINNIE Please, a loser like you will never amount to anything. This harsh remark seems to leave Hal genuinely stunned. HAL Wow...If that's how you feel...I guess we should then talk about what kind of severance I'm gonna get. EXT. KINGPIN BOWLING - DAY TWO BRUISERS open the door and throw Hal out onto the street. He quickly picks himself up and turns back toward the building. HAL Hey...what about my ball? A bowling ball sails past him, just missing his head. HAL Thank-you! EXT. CHANNEL 7 NEWS BUILDING - DAY The massive building with a giant 7 on the roof stands in the heart of Metro City. INT. CHANNEL 7 NEWS BUILDING - OFFICE - DAY The cubicles and offices are alive with the hustle and bustle of a busy news day. Phones are RINGING, REPORTERS are TALKING, and Editors are SHOUTING. The elevator doors open and out steps Roxanne Ritchi. 17. Everything stops as the entire office suddenly falls SILENT. Somewhat taken aback by the reaction, Roxanne scans the room to see every eye on her. ROXANNE It's...um...It's good to be back. Thanks for everyone's cards and concerns. I really appreciated it - now I'm ready to climb back on the horse. No one is budging - their looks of pity are really starting to make her uncomfortable. The back office door suddenly opens and out comes FRANK BONIN, the gruff, middle-aged Producer of Channel 7 News. Noticing the silence, he looks up and sees the sad expressions on everybody's face. FRANK Someone die or something? He suddenly notices Roxanne - both feet are placed firmly in his mouth. FRANK (cursing himself) Oh, Jesus. ROXANNE It's okay. Frank quickly walks up to Roxanne and takes her gently by the arm. FRANK Come on into my office, sweetie. INT. CHANNEL 7 NEWS BUILDING - FRANK'S OFFICE - CONTINUOUS He sits her down on his leather couch, then quickly turns toward his door. FRANK Can we get this woman some water for God's sake? (to Rebecca) I gave you two months off. What're you doing back? People are gonna think I'm a slave driver. 18. ROXANNE Aren't you? FRANK Yeah, but I don't want people to think it. ROXANNE Frank, listen. I want to go back to work. I NEED to go back to work. FRANK ...You're hysterical, aren't you? Frank sits down on the couch and blankets Roxanne with A WARM EMBRACE. ROXANNE What're you doing? FRANK Keeping you warm before you go into shock. (toward the open door) DO I HAVE SLICE OPEN A CAMEL HUMP TO GET A GLASS OF WATER AROUND HERE? A SECRETARY quickly enters with a bottled water. She sets it on the table in front of them and leaves. Roxanne pulls herself out of Frank's grasp and stands up to face him. ROXANNE It was a traumatic experience. Yes, everyone knows Uberman and me were...close. But what I really need - what would really make me better is getting back to work. There's a sudden awkward silence from Frank. FRANK Well, that's going to be... ROXANNE I thought you'd be happy to have me back. 19. FRANK Oh, we are. Honey, nothing makes us happier than to have our girl back, but... ROXANNE Yes? FRANK Things have sorta...changed. ROXANNE In three weeks? FRANK Listen, I'm not one who likes to open up wounds - especially ones that are just starting to scab, but you were sorta our go to girl for the exclusive on Uberman. And now that he's gone...I moved Brad into your anchor spot. ROXANNE (disgusted) Brad? Brad Helms? The man is an idiot. FRANK It's the suits. They think it's time to switch things up. ROXANNE Oh, because they can't use me to get the big story. FRANK C'mon, Roxie. Using is in the nature of what we do. They used you, you used Uberman. Everybody's happy. ROXANNE (defensive) I didn't use him. FRANK Oh, I didn't mean that. I know you two were in love or something. My bad. ROXANNE We were. 20. FRANK And that's great. ROXANNE Very in love. There's a hind of self-doubt in Roxanne's expression, as if she's failed to convince even herself of this. ROXANNE Okay. So, where are they going to move me if Brad has my spot? FRANK ...Human interest. ROXANNE Bake sales and pet stories. FRANK I told them I wouldn't be surprised if you just upped and quit. You busted your ass for that desk. Roxanne can hardly get it out - she's busy swallowing her pride ROXANNE I'll take it. Frank looks up at her, not believing what he's hearing. FRANK What? EXT. ABANDONED METRO CITY LIBRARY - NIGHT Amongst the jungle of high rises, one small building stands out from the rest - A tiny, forgotten piece of 19th century Gothic architecture. LIGHTENING FLASHES, revealing TWO CONCRETE GARGOYLES holding a cracked plaque, reading: METRO CITY LIBRARY. INT. ABANDONED METRO CITY LIBRARY - NIGHT A mixture of old and new. Dusty Victorian furniture and dilapidated bookshelves sit side by side with pristinely futuristic machinery. The building has been converted into Master Mind's new SECRET LAIR. 21. In the center of the main room is a three storey tall GLOWING BLUE ORB. At the base of it is a sign that reads "Reactor - Don't Touch." We PAN OVER to the READING ROOM where Master Mind is sitting on a couch watching TELEVISION. REPORTER ON TELEVISION (O.S.) It's been nearly six weeks, and still no word on the whereabouts of billionaire playboy, and philanthropist, Wayne Scott. Tune in at 11:00 as we look into what has become Metro City's biggest mystery. TELEVISION NARRATOR (O.S.) We now return to "The Hero of our Hearts: The Uberman story." Einstein and Plato come into the room holding a BAG OF LOOT. EINSTEIN Just robbed the diamond exchange. MASTER MIND (feigning pleasure) Great, great. Put it on the pile. Einstein tosses it on a LARGE PILE of purloined valuables in the corner of the room. EINSTEIN Anything else today? MASTER MIND No. Master Mind turns his attention back to the screen. Plato sees that Master Mind is in a funk and tries to snap him out of it. PLATO (cheerfully) Sir, the new reactor is installed. Plato nods to the giant orb. PLATO Do you want to throw the switch? I know how you love to start reactors. 22. MASTER MIND Maybe later. Einstein gives Master Mind a funny look then exchanges glances with Plato before leaving the two of them alone. Without turning away from the TV, Master Mind addresses Plato. MASTER MIND (CONT'D) What is it, Plato? PLATO (nervously) Sir, I can't help but notice that you've been...a little down lately. MASTER MIND When I want your opinion I'll beat it out of you. PLATO Yes, sir, I know, but please forgive my impertinence. It's just that you seem to have lost your lust for our profession. You've stopped going on jobs and spend most of your time watching Uberman specials. Master Mind relaxes slightly and turns to face the window in a classically contemplative pose. After an overdramatic beat... MASTER MIND I have defeated my greatest enemy. I have free reign over Metro City. I have more wealth than a thousand Sultans. I've achieved all I have worked for...so why am I so unhappy? He walks over to a PAINTED PORTRAIT that looks almost exactly like him, except slightly older, maybe meaner - MASTER MIND'S FATHER. MASTER MIND I mean, my father, god rest his evil and tormented soul, raised me straight from the test tube to be a symbol of evil. (MORE) 23. MASTER MIND(cont'd) And, I have accomplished something he had only dreamed about - the destruction of Metro City's champion. I tell you, I've always lived with this unquenchable thirst. I thought it was to make him proud or to get absolute power. But now that I've pretty much accomplished both, I am at a loss. PLATO ...I sort of have a theory about all that. MASTER MIND (snippy) Oh, really? PLATO Well, for one thing, maybe Uberman was more important to you than you thought. MASTER MIND He was a worthy rival. Sometimes I wonder, did he consider me his evil equal or was I just an annoying, little gnat to him? ...What's the second part? PLATO I think you sort of have a thing for Roxanne Ritchi. Master Mind quickly takes his lackey by the throat. MASTER MIND YOU WORM! HOW DARE YOU! WHERE WOULD YOU GET SUCH A NOTION? PLATO Sir, your plans always involve Ms. Ritchi either being kidnapped or placed in danger. If that's not love, I don't know what is. It's the grown up equivalent of dipping her pigtails in the ink well. Don't you see? She's the one treasure that's always escaped you. From Master Mind's expression, we see Plato's words beginning to ring true. 24. INT. RESTURAUNT - DAY Roxanne is having lunch with several girlfriends sitting around her, gabbing. FRIEND #1 I can't believe you came back so soon. FRIEND #2 Are you sure it's not TOO SOON, honey? ROXANNE I just wanted to get back to work. FRIEND #3 What we need to do is get you back on the saddle...the love saddle. Friend 1 and 2 give 3 disapproving looks. FRIEND #3 It's been three weeks. FRIEND #2 She just lost the love of her life, Grace. A WAITER comes by with a tray of CAESAR SALADS and begins setting them out for the ladies. ROXANNE I keep trying to tell people it wasn't really like that. Uberman and I - We were kinda having problems. We broke up. The waiter ALMOST DROPS HIS TRAY AT THIS. The women are too shocked by Roxanne's revelation to notice. FRIEND #1 You broke up with Uberman! FRIEND #3 You must have REALLY, REALLY high standards. I mean, you were dating a god. I mean, what's it take? ROXANNE Maybe someone who's a little more aware of his faults. Someone a little more sensitive. 25. FRIEND #3 Right. Someone who listens, sexy but attainable with cute little cheeks like a hamster and heartbreak in his eyes. She turns to Friend one and two to explain. FRIEND #3 She wants John Cusack. FRIEND #2 The actor? FRIEND #3 No, the famous pediatrist - Yes, the actor. Ever since we were teenagers, Roxanne's totally had the hots for him. ROXANNE Well, until he miraculously comes walking into my life, I'm just going to take a little reflection time for myself. The waiter gets a confused look on his face then slips away as Roxanne and her friends continue to chat away. EXT. RESTURAUNT - DAY The waiter tosses his apron in a trash can, then rolls up his sleeve and presses A STRANGE LOOKING DEVICE STRAPPED TO HIS WRIST. His image gets staticy, like a TV station going out, then disappears - revealing the man's true form underneath: MASTER MIND! MASTER MIND Who the hell is John Cusack? EXT. CITY STREET - DAY A YOUNG MOTHER pushes her baby stroller past a building construction site. ACROSS THE STREET A local POLITICIAN addresses a group of REPORTERS on the sidewalk, including Roxanne. 26. POLITICIAN The Fifth Avenue Renovation Project, which I championed, will breath new life into the downtown area. New life means new jobs and new revenue. ROXANNE Councilman, is it true that your brother-in-law's construction company won the contract for this project? POLITICIAN Well...er...yes, but...look I'm not here to answer a lot of crazy questions... YOUNG MOTHER The young mother stops halfway down the block, reaches into the stroller and tries to comfort her now crying baby. Above her, a CRANE is maneuvering a pile of STEEL GIRDERS to an upper floor. Hal comes around the corner and heads in her direction. CRANE The crane GRINDS TO A HALT. The OPERATOR has a confused look on his face as he moves levers back and forth in an effort to fix the problem. Hal stops a few feet from the woman and stoops down to tie his shoe. CRANE The operator's hand slips off the lever, hitting a RED BUTTON. To his horror the crane DROPS ITS LOAD OF STEEL. HAL AND THE WOMAN The woman looks up to see the girders seconds from crushing her and her baby. She screams. Hal looks up and sees it as well. He starts to run out of the way and crashes into the woman and stroller. ACROSS THE STREET 27. The reporters turns their cameras just in time to catch on film what appears to be Hal pushing the woman to safety just as the GIRDERS CRASH TO THE GROUND. HAL AND MOTHER Tears of joy in her eyes, the woman picks up her baby and kisses it. Hal struggles to catch his breath as the mother turns to him. YOUNG MOTHER Thank you! Thank you for saving me and my baby! She hugs him with her free arm, weeping with joy. HAL (not knowing what she's talking about) Huh? He's a little uncomfortable with the woman's public display of affection and the small child in-between their embrace. HAL (CONT'D) There, there. Hal slowly eases out of the woman's grip. HAL (CONT'D) Okay, we better...well, I hear these little guys smother easy. The reporters rush over and surround Hal and the mother. ROXANNE What's it feel like to be a hero? Hal looks up at Roxanne. Instantly, he's captivated by her beauty. HAL Well...I'm just a man doing what men do. You're Roxanne Ritchi, aren't you? They're suddenly interrupted when another reporter pushes his way in between them. REPORTER Were you scared? 28. HAL Scared? Who had time? The reporters eat this up. INT. ABANDONED METRO CITY LIBRARY - NIGHT TELEVISION John Cusack stands in the rain looking up at a window of a two story house. He holds up a BOOMBOX and "In Your Eyes" by Peter Gabriel begins to play. From the couch, Master Mind and his minions watch. MASTER MIND John Cusack, huh? So all I have to do is have a cute puppy dog stare, be willing to make a fool of myself and - Oh, REMOVE BOTH MY BALLS. He turns to see Da Vinci watching the movie and wiping a tear from his cheek. MASTER MIND Please, get a hold of yourself. INT. BOOKSTORE - NIGHT Roxanne is carrying a large paper coffee cup in her hands as she peruses the isles. She sets it down on a shelf to pull a book out and ends up KNOCKING THE DRINK OVER. ROXANNE Shit. She goes to pick it up when someone bends down and picks it up for her. Looking up to thank him, Roxanne is suddenly stunned speechless - It's popular and critically acclaimed actor JOHN CUSACK, or rather Master Mind disguised as him. "JOHN CUSACK" Oh the humanity - it was a Venti. ROXANNE (stunned) You're...you're. "JOHN CUSACK" Yes, it's me. John Cusack...the actor. 29. He notices the book she's reading. "JOHN CUSACK" Hey, is that Shelly? Wait, I think remember something from that one - Let's see: "My head is screaming `I want you and need you' - my heart it keeps reaching to see you and feel you - yet in the end, I'm alone once again." Wow, I scare even myself. I'm sorry. I'm just really into poetry. Probably because I'm so sensitive and always going to great lengths to express myself. But enough about me. Can I fill you up? ROXANNE (captivated) ...Yes. (catching herself) I mean, excuse me? "JOHN CUSACK" Can I fill you up? Your coffee. ROXANNE Right. INT. BOOKSTORE CAFE' - LATER Roxanne talks as John Cusack listens to her every word intently. ROXANNE I did have a boyfriend - until fairly recently. She suddenly begins to feel the stares around her as passers- by being to notice who she's with. ROXANNE I'm sorry - this is so surreal! "JOHN CUSACK" Yeah, they charge way too much at these places - Now back to your boyfriend. I'm interested and compassionate. I want to know about you. 30. ROXANNE Things were complicated. He was a man married to his work. There was...there was a lot of competition in his line of business. I'm sure you know what that's like. "JOHN CUSACK" Sure. In my business, one thing I have is RIVALS. For example, mine is...uh...Lou Ferr...igno. ROXANNE ...The body-builder who used to play The Hulk on TV? "JOHN CUSACK" Did he? Well, we're always up for the same roles. Did your boyfriend have someone like that? A particular rival that was always getting his goat - so to speak? ROXANNE Well...one rival in particular seemed to get more of his attention than I ever did. But enough about my problems. "JOHN CUSACK" NO, TELL ME MORE!!! Suddenly realizing his outburst, he begins COUGHING to mask it. "JOHN CUSACK" (CONT'D) I'm sorry. I got a whooping cough. Had it ever since Serendipity. I WONDER WHERE OUR REFILLS ARE!!! (fakes cough) See, there it goes again. Please, go on. ROXANNE Right, well, he seemed to need him more than he needed me. "JOHN CUSACK" How do you mean? 31. ROXANNE It was conflict he thrived on. He always said he wouldn't know what to do with himself if Master - I mean, this guy were gone. It was like he needed it, like oxygen. The answer to his mental funk hits him like a bolt of lightening. He turns away from her as if for private time. "JOHN CUSACK" (almost to himself) I think I finally understand...The only logical answer is to recreate that rivalry - or if that's impossible, create one of equal structure. That's it! ROXANNE What? John Cusack snaps out of his dream-like haze realizing she's heard every word. "JOHN CUSACK" Oh, sorry, sorry. Just rehearsing for a part...where I play a man who talks to himself at inappropriate times. In a sudden rush, he rises out of his chair. "JOHN CUSACK" I have to go right now, but I'd really like to see you again - if that's alright. Roxanne looks up at him - She can't help but laugh at the craziness of the situation. ROXANNE I'd love that. INT. ABANDONED METRO CITY LIBRARY - DAY Master storms in the office to find Plato and Einstein playing darts with the original Mona Lisa. EINSTEIN Got her nose! MASTER MIND I've got it! 32. Everyone stops what they're doing upon seeing that their master has returned. MASTER MIND I've got it! MASTER MIND It's plain and simple. Extraordinary minds need extraordinary stimulation. Without that stimulus they wither and die. Therefore, there is only one logical conclusion: I must create a new superhero. EINSTEIN Yeah, maybe that's not such hot idea... MASTER MIND (ignoring him) Prepare for Operation Superhero Genesis! INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY The lab is slick, white and ultra modern. Dressed in a lab coat, Master Mind enters through a SLIDING GLASS DOOR rubbing his hands excitedly. MASTER MIND Prepare the subject. He glances down into a large HOLE in the floor to see a naked thirty year old man, SEVERS, shivering. Above the hole, a huge vat dangles precariously. Master Mind steps behind a glass partition next to Plato and Einstein. MASTER MIND (CONT'D) Plato, pour the toxic waste. Plato throws a switch causing the vat to tip hundreds of gallons of green and brown goo into the hole. MASTER MIND (CONT'D) Drainage. The slime is sucked out through the floor, leaving a goo- soaked Severs. 33. Master Mind looks into the pit. MASTER MIND (CONT'D) Well, Severs? SEVERS I feel fine. Just a little sticky, but aside from that everything's completely - BOOM - Severs explodes. A hail of blood and tissue covers Master Mind and his men. For a good ten seconds nobody moves an inch. Finally... MASTER MIND Okay then. INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY Through a glass WATER TANK we see a man breathing normally. MASTER MIND And this one? PLATO We attached gills to him. He can breath under water. MASTER MIND Ah. Does he have extraordinary strength? PLATO Well...no. MASTER MIND Can he fly? PLATO No. MASTER MIND Resilient to weapons fire? PLATO No. MASTER MIND He just breathes under water, then. PLATO Ah...yeah. 34. Master Mind rolls his eyes and walks away. INT. ABANDONED METRO CITY LIBRARY - LABORATORY - DAY The next guinea-pig, STENWICK, is standing in a sealed glass tube not much wider than himself. MASTER MIND Plato, the radioactive spider, please. Plato throws the switch DROPPING A SINGLE SPIDER onto Stenwick's arm. Stenwick looks and winces as it bites him. STENWICK Ow! He brushes the spider off. MASTER MIND Anything, Stenwick? STENWICK (shaken) No. Ah...sir, I didn't know this was about spiders. I have a pretty severe case of arachnophobia. Master Mind thinks for a moment, then turns to Plato. MASTER MIND We're gonna need more venom. Plato throws another switch, this time DUMPING THOUSANDS OF SPIDERS on poor Stenwick. His SCREAMS begin to fade as he's engulfed with swarms of crawling arachnids. MASTER MIND (CONT'D) How `bout now, Stenwick? ....Stenwick? INT. ABANDONED METRO CITY LIBRARY - OFFICE - DAY Master Mind is pacing back and forth. The muted TV plays in the background. MASTER MIND This has proven to be a challenge. I just don't know what I want. What do I want? 35. He stares at Einstein, Da Vinci and Plato, but they offer no advice. MASTER MIND (CONT'D) I want a man of moral fiber with a strong sense of right and wrong. Someone who doesn't seek power - instead, they must have it thrust upon them and find, within themselves, the courage to rise to the occasion. Einstein lets out a short laugh, getting everyone's attention. EINSTEIN Yeah, well, it sounds like what you want is Uberman. Master Mind snaps the fingers of his non-metal hand. MASTER MIND That's it! Why make a copy when the real thing will do? The lackeys look at each other, they can't believe what they're hearing. EINSTEIN I was just kidding, sir. In case you forgot, you actually burned Uberman alive. MASTER MIND Then we'll make a new one. Plato, bring me the box! MINUTES LATER Master Mind and the lackeys stand in a circle around a small table. Plato places a STAINLESS STEEL CHEST in the tables center. As Master Mind opens it, he's immediately doused in WHITE GLOW emanating from inside. MASTER MIND Behold - Uberessence. The very thing that gave Uberman his superhuman powers. 36. EINSTEIN Where the hell did you get that? MASTER MIND Oh, I shot him with a power sucking gun and had this idea to use this to clone a whole army of evil Ubermen. I'm not sure why I never got around to following up with that. PLATO I believe he defeated you before you could, master. MASTER MIND ...Right. Man, he was good! DA VINCI You want another volunteer, sir? MASTER MIND Not another volunteer driven by the need for personal gain. Somebody else, somebody pure. Master Mind turns to see an INTERVIEW WITH HAL playing on the muted television. Underneath his face is a blue caption with white lettering that reads: "Hal Stewart - Metro City's Newest Hero?" NEWS REPORTER ...who risked his own life to save that of a young mother and her child. HAL Please, please, you're embarrassing me. I saw someone in need and I helped them. What more can we ask of ourselves. I ask you, what more? A smile creeps across the evil one's face. MASTER MIND (CONT'D) Somebody like him! EXT. CITY STREET - DAY Plato is sitting in the van, staring into a pair of binoculars as he speaks on a cellphone. 37. PLATO Yeah, sir. This guy is a real piece of work. He used to teach bowling at Kingpin's. INT. MASTER MIND'S HIDEOUT - DAY Master Mind is sitting with his feet up on a computer console as he speaks to Plato. MASTER MIND (into phone) A modest profession to brilliantly hide his true heroic nature. I love it. EXT. CITY STREET - DAY PLATO Then you are absolutely going to love this - We follow Plato's line of sight across the street where we see HAL PLAYING WITH A LARGE GROUP OF BLIND CHILDREN. PLATO - He volunteers at a school for the blind. INT. MASTER MIND'S HIDEOUT - DAY Intrigued, he suddenly sits up in his chair. MASTER MIND He volunteers. He doesn't ask for any reward for his deeds. The fates are shining down on me. This Mr. Stewart is truly an unselfish soul. EXT. BLIND SCHOOL - DAY From a distance, Hal seems to be consoling an upset child who's sitting on a rock. But up close... HAL You greedy little bastard. I already gave you a twenty. BLIND KID Hey, you want me to play along? Then pay up, bitch! 38. HAL Fine, but you better be convincing. He gives the kid a bill out of his wallet and looks over his shoulder to see a HOT TEACHER walking toward them. HAL Here she comes, go to work. Like a miniature Brando, the blind kid buries his face in his hands and begins to cry. BLIND KID (weeping) Why can't I see! Why God? Hal puts a warm consoling hand on the weeping boy's shoulder. HAL Hey, Peter. C'mon champ, let me look at you. The Hot Teacher stops and curiously watches from a distance. The boy looks up at Hal, tears running down his dark sunglasses - he should get an Oscar. HAL You know, in life we're all given no more than we can bear. This happened to you maybe because you were meant to rise above it - Maybe to be an inspiration to the other little Peteys out there. BLIND KID You really think so, Hal? HAL Hey, does it LOOK like I'm lying? Now c'mon, go feel your way to class before you get your little butt suspended. The boy stands up and is about to take off. HAL Petey, wait a minute. Hal uses his shirt sleeve to wipe the tears away from the boy's face before sending him on his way. 39. The Hot Teacher grabs her chest. Her heart is about to absolutely melt. HAL Don't run into anything! EXT. STREET - CONTINUOUS Plato lowers his binoculars. From his perspective, Hal should be next in line for popehood. PLATO I think I've seen enough, sir. This is your guy. MASTER MIND (O.S.) (over radio) Then return to base. We have much work to do. Plato starts up the van and pulls away. INT. BAR - DAY It's a busy night. A couple of trucker types are shooting pool as the bartender slings drinks. Hal is nursing a beer at the bar when he suddenly notices a very ATTRACTIVE WOMAN sitting next to him. As he goes to straighten his stool-posture, Hal suddenly catches himself on the bar's TELEVISION - it's a story about how he saved the woman and her baby at the construction site. He turns back to the Attractive Woman next to him, then back to the TV. A plan of attack is forming. HAL (obviously playing it up for the woman's benefit) Oh, there it is again. This is really getting embarrassing now. The woman looks up at the screen and gives Hal a double-take. ATTRACTIVE WOMAN Oh my God! It's you! You're the man who saved that woman and her baby the other day! It is you, isn't it? TRUCKER #1, getting a drink at the bar next to them, OVERHEARS. 40. Hal rolls his eyes and puts his hands up in the air. HAL (to Attractive Woman) Oh, crap. You got me. TRUCKER#1 taps Hal on the shoulder. TRUCKER#1 Let me tell you something. That was just about the bravest damn thing I've ever witnessed. (he turns to the rest of the bar) Hey, everybody! This guy's the hero from TV! The bar ERUPTS IN CHEERS. MOMENTS LATER Hal is riding on the shoulders of TRUCKER#2 and TRUCKER#3 as `I'm Holding Out For A Hero' plays on the jukebox. TRUCKER#1 suddenly puts his hands in the air. The room quickly goes silent. TRUCKER#1 I want to give you something. He reaches into his pocket and takes out a medal. He holds it up in the air for everyone to see. TRUCKER#1 (CONT'D) Lost my whole platoon. They were a lot a good boys, a lot of good boys. That was just the way things were in "The Grenada." I'd rather a real hero have this. Trucker#1 gives the medal to a speechless Hal. ATTRACTIVE WOMAN Hey, you're on TV again. The crowd looks up at the Television. TELEVISION - CONTINUOUS The anchor man, BRAD HELMS (early 40's, amazing mustache), suddenly has a memo passed to him. 41. BRAD HELMS This just in. Upon a second look at that tape from this morning, which we'll now replay for you, it appears it was not the heroic act it first seemed to be. The tape shows Hal running in slow motion. BRAD HELMS (O.S.) (CONT'D) With the tape slowed down you can actually see the man push the woman and her child out of the way in an effort to save his own life. The tape shows Hal, in a clear act of self-preservation, pushing the woman and child out of the way. CUT BACK TO: INT. BAR - CONTINUOUS In unison, everyone turns their heads back to Hal. HAL I guess that looks kinda bad. Trucker#1 snatches his medal back. EXT. NEARBY ROOF - NIGHT Master Mind, Da Vinci and Plato look down, spotting Hal cutting through a dark alley. DA VINCI There he is, boss. Da Vinci hands Master Mind a fantastic looking silver rifle. MASTER MIND Now, we're sure this won't kill him? PLATO Yes, sir. He'll just feel a slight electrical shock. MASTER MIND Good. Master Mind raises the rifle and aims it at Hal. 42. EXT. ALLEY - NIGHT Hal wipes the blood from his nose with his shirtsleeve. A LIGHTENING BOLT suddenly zaps Hal in the back. His teeth spark and arc electrons as his entire body shakes and shudders violently. He finally collapses, knocking over a row of garbage cans. EXT. NEARBY ROOF - NIGHT An angry Master Mind slaps Plato. MASTER MIND Slight electrical shock? EXT. ALLEY - NIGHT Hal lies flat on his back, his jacket smoldering. Dazed, he slowly rises to his feet and looks up at the sky. HAL God, I hate the weather in this city. Hal walks off into the night as he attempts to slap the emitting smoke from his jacket. EXT. NEARBY ROOF - NIGHT Master Mind turns to Da Vinci. MASTER MIND Follow him. INT. HAL'S APARTMENT - NIGHT It's a dirty, small studio. Laundry lies everywhere, dishes are piled in the sink and the litter box looks like a minefield. Hal comes staggering in. Through his POV we see the lights wobble and streak like a hallucination. He shakes his head trying to clear thing up, but it looks worse. Hal makes his way to the kitchen table and plops down on a chair. The room begins to swim. His CAT jumps on the table and sits down in front of him. 43. From Hal's POV the cat's face looks like we're seeing it through a kaleidoscope. Hal seems fascinated by it. CAT You don't look so good, man. HAL I don't feel good. I was struck by freaking lightening. Suddenly Hal realizes his cat's talking to him. HAL (CONT'D) AAAAAAHHHHH! You can talk? CAT No, you're just hallucinating. By the way, we're out of orange juice. HAL AAAAAAHHHHH! Hal jumps up, trips over a cardboard box and knocks himself out on the coffee table. INT. HAL'S APARTMENT - MORNING Hal lies in the same position we left him last night. He sits up and grabs his head. He looks like he has the worst hangover in the world. Finally, he remembers last night. He looks around, but not really sure what he's looking for. HAL Man... Shaking his head, he walks to the kitchen and opens the refrigerator. He pulls out an orange juice container and puts it to his mouth. It's empty. As if suddenly remembering something he looks from the carton to the cat, who is busy cleaning himself. He shakes the thought from his mind. BATHROOM Hal lifts the seat and unbuckles his pants. 44. HAL'S FACE He stares at the ceiling with half closed eyes. The inevitable sound of urine hitting water starts. A content look washes over his face. There is a distinct sound of porcelain CRACKING and SPLINTERING. The sound intensifies. Hal looks down to see his URINE STREAM SMASHING THE TOILET. HAL (CONT'D) Oh, God! He whips his stream away only to cut a LONG RIP IN THE WALL. HAL (CONT'D) Oh, God! He freaks out and begins to lose control of his flow as it destroys everything he accidently aims at; the bathroom mirror, a bottle of cheap cologne, the bathroom window. HAL (CONT'D) Oh, God! He aims back for the toilet, which is pretty much rubble now, to see the floor give way. Finally, the pee stops and he glances down the hole. He sees his downstairs NEIGHBOR sitting at his breakfast table. He has a fork halfway to his mouth as he stares at the smashed toilet on his pancakes. EXT. STREET - DAY Hal turns the corner to see his bus pulling away from the stop. HAL Wait! He starts running after it. ZOOM - HE TAKES OFF LIKE LIGHTENING. HAL (CONT'D) Whoa, whoa, whoa! Unable to stop, he SLAMS INTO THE BACK OF THE BUS and falls back to the ground. 45. As the bus continues on he sees an INDENTATION of his torso right below the rear window. Stunned, to say the least, he rises to his feet. HAL (CONT'D) Something's not right here. He slaps himself in the face as hard as he can. HAL (CONT'D) Wake up! Wake up, Hal! HONK! Hal spins around to see a car barreling toward him. He goes to jump out of the way - ZOOM - he FLIES TWO STORIES UP, nails a building and comes crashing back down to the sidewalk. Hal sits up, disheveled and scared. HAL (CONT'D) Okay, okay. Let's get it together, man. He closes his eyes in an attempt to will back his sanity. HAL (CONT'D) This is just some sort of...episode. It will pass, it will pass. He opens his eyes and looks down the street. A BEAUTIFUL NAKED WOMAN is coming toward him. HAL (CONT'D) Well, not too fast I hope. As she passes him and turns the corner out of his view he catches ANOTHER NAKED WOMAN - an old disgusting one. HAL (CONT'D) Yes, fast, fast! He turns away from her in horror only to see AN ENTIRE BLOCK OF NAKED PEOPLE going about their business. He rubs his eyes and looks down the street again. Everyone has returned to a clothed state. 46. He relaxes a little until he looks down and notices that he's floating a foot off the ground. HAL (CONT'D) I think I need to go home. INT. HAL'S APARTMENT - DAY Hal's front door CREAKS as it slowly opens, revealing Master Mind. He walks over to the bathroom and smiles to himself as he notices the giant hole in the floor. MASTER MIND Welcome to your second birth, Hal Stewart. Master Mind continues to survey the room. He stops to look over a "KARATE KID" POSTER on Hal's living room wall. He focuses on the majestic image of Pat Morita teaching a young Ralph Macchio to kick. MASTER MIND (CONT'D) Instruction is very important in the formative years. Every hero needs a mentor, a father figure to look up to. He presses his special watch, causing his body to MORPH INTO THE SPITTING-IMAGE OF PAT MORITA. "PAT MORITA" Perfect. INT. HAL'S APARTMENT - DAY Hal enters, grabs a bottle of vodka from atop of the fridge and takes a long pull from it. VOICE (O.S.) A man will usually find that if he drinks from a bottle, eventually, the bottle drinks from him. Hal does a SPIT TAKE. In the corner a darkened figure stands. HAL Who are you!? 47. VOICE I am the guide on your journey. Fate has chosen you to be it's champion. Pat Morita steps out from the shadows. Hal passes out again. LATER We are close on Hal's face as his eyes flutter open. He appears to be lying on the couch. He hunches up on his elbows, looks around, but everything is as it seems. He lays his head back down. HAL Thank God. It was a dream. Man, I must be losing it. A voice sounds right next to his ear. "PAT MORITA" (O.S.) You know you're out of orange juice? Hal leaps up to find he's been resting his head on Pat's lap. HAL Jesus! This isn't happening, this isn't happening. Hal backs away and trips over a box. "PAT MORITA" Calm. All things must be filtered through calmness. HAL Bullshit! Sometimes it's best to freak out. "PAT MORITA" I think we must work on your attitude first. HAL Look I'm gonna call the cops in about two seconds if you don't get out of here. 48. Pat rises and walks to Hal. He's so calm it makes Hal calm. "PAT MORITA" Are you calm now? HAL Yeah, I'm okay. Pat slaps him across the face hard. "PAT MORITA" Good, because we've got a lot of work to do. Hal grabs his jaw. HAL What the hell was that for? "PAT MORITA" Rule number one: expect the unexpected. HAL Can you just tell me what this is all about? "PAT MORITA" The heavens are not in the habit of bestowing a gift such as this to just anyone. You are being rewarded for being a man of great moral fortitude with an unwavering belief in humanity. HAL That's me alright. "PAT MORITA" I am to train you so you may fulfill your destiny to defeat the great menace to Metro City: Master Mind. Pat gets up and walks toward the door. "PAT MORITA" (CONT'D) Come. HAL We're are we going? 49. "PAT MORITA" To train. EXT. PAT'S CAR - DAY Pat is sitting in the driver's seat. The car is bumping up and down. "PAT MORITA" Strength is just as much in the mind as it is the muscle. Remember, both need to be exercised. We PULL BACK to see Hal lifting the car up over his head. He's hardly straining. HAL I'M LIFTING A FREAKING CAR!!! Pat leans on the HORN. "PAT MORITA" Hey, Corky? You listening? Two highly attractive female joggers run by. They're clearly impressed with Hal's show of strength. He smiles and mouths a "hello." HAL Yeah, work both muscles. EXT. DESERT - DAY Pat cocks back the chamber of a .357 MAGNUM. He holds it up and carefully takes aim...at Hal's chest. "PAT MORITA" Trust me. HAL What are you doing!? "PAT MORITA" An invulnerability test. Something wrong? HAL Uh...yeah. I would prefer not to get shot. Do not fire that thing! Frustrated, Pat lowers the gun. 50. "PAT MORITA" You're bulletproof. HAL Okay, do you know that for sure? Pat quickly aims and fires. Hal lets out a high pitched scream as the bullet ricochets off his chest. "PAT MORITA" I do now. Hal looks down at his chest, not so much as a scratch. HAL You suck. EXT. SKY - DAY Hal is in the air flying in a sitting position. He's weaving back and forth. HAL Ice Man, I got a bogie on my tail. Two Russian Migs coming in hard and fast. "PAT MORITA" Hey! HAL What? Hal looks down to see Pat Morita yelling at him from the roof of a building down below. "PAT MORITA" What did I tell you? Stomach down, hands up. Hal sighs and assumes the proper superhero in-flight position. HAL God, I feel so gay. Pat's CELL PHONE begins to RING. He answers it. "PAT MORITA" (in Master Mind voice) What is it? 51. ROXANNE (V.O.) John? Pat panics. He looks up to make sure no one is in earshot. He sees Hal now doing somersaults in the air. HAL YEEEE HAWWWW! Pat turns his attention back to the phone, talking in his John Cusack voice. "PAT MORITA" (in Cusack voice) Yes, it's John Cusack. ROXANNE (V.O.) Hi, it's Roxanne. Listen, I...I really enjoyed talking with you the other day. "PAT MORITA" ...As did I. ROXANNE (V.O.) Great. God, I feel really silly, and if you have a lot going on I totally understand. But, I was wondering if you maybe wanted to have lunch. He can't believe what he's hearing. "PAT MORITA" (excited) I'd love to! He quickly recovers his composure. "PAT MORITA" (CONT'D) I mean, I AM a little hungry. ROXANNE (V.O.) Great. How does the park sound, around noon-ish? "PAT MORITA" Sure! ROXANNE (V.O.) Great, see you then. 52. Pat hangs up the phone and returns it to his pocket as Hal lands behind him. HAL WHOOOOA! Man, that is so cool. It's like fly - Oh my God, I almost said it was like flying. "PAT MORITA" For the rest of the day I want you to continue to practice your flying posture. HAL Why, where're ya going? "PAT MORITA" ...To do something...mysterious ...and Asian. HAL Say no more, bro. I'll just keep at it, then. EXT. PARK - DAY John Cusack and Roxanne eat WRAPPED SANDWICHES while walking through Metro City Park. ROXANNE How's your sandwich? "JOHN CUSACK" It's quite delicious. ROXANNE Hope you don't think I'm too forward. Some men are intimidated when a woman asks them out. I just find you really easy to talk to. "JOHN CUSACK" And I you. ROXANNE You know, you're not at all like you are in the movies. "JOHN CUSACK" I'm not? 53. ROXANNE Yeah. I don't know - You have this strange, refined way of speaking. "JOHN CUSACK" I do? That is most interesting. ROXANNE Anyway, when we were talking the other day I just felt, even though we only talked for a couple of hours, that we've known each other for years. "JOHN CUSACK" I know just what you mean. Roxanne bites into her sandwich. ROXANNE You know what? This sandwich is disgusting. She tosses it in a nearby garbage can. ROXANNE (CONT'D) Of course I already ate half of it. I wonder what that says about my character? "JOHN CUSACK" It means you don't give up on a sandwich. You see that it has potential, and you give it every chance to be all it can be. Roxanne smiles at his analogy. ROXANNE Thanks, but knowing me, I was probably projecting my expectations of what a lunch should be on the sandwich. It might have been okay at first, but I just made it bitter. John Cusack notices Roxanne's smile starting to fade. "JOHN CUSACK" Is that what happened with your last sandwich - I mean, boyfriend? 54. ROXANNE When I look back, I probably shouldn't of expected so much from him. He was already a giving person. You know, one of those go out and save the world types. "JOHN CUSACK" I've run into a few. ROXANNE I was selfish, I guess. I didn't want to share him with anybody else. "JOHN CUSACK" It sounds like he was a special man. ROXANNE They broke the mold. John Cusack arches his eyebrow in a very familiar manner. "JOHN CUSACK" Perhaps not. INT. ABANDONED WAREHOUSE - DAY Hal walks up to Pat Morita sporting a Lone Ranger-type mask and wearing a purple and red superhero costume. It's not unlike Uberman's except for a giant "T" on his chest. (From here on, Hal is referred to as TITAN) TITAN What's the "T" stand for? "PAT MORITA" Titan. TITAN What's that supposed to mean? "PAT MORITA" It's from Roman mythology. Zeus's father...oh, just go with it. You look perfect. TITAN I don't think this mask is big enough. Are you sure no one is gonna recognize me? 55. "PAT MORITA" It's fine, just don't slouch. It's all in the posture. He grabs Titan's shoulders like a proud papa. "PAT MORITA" (CONT'D) It is time. INT. BANK - DAY There is a long line of people snaked around the velvet ropes. They're all waiting for their chance at the one open teller window. Four men wearing BEATLES MASKS(JOHN,PAUL,GEORGE,AND RINGO)and CARRYING SHOTGUNS enter the bank. John fires a shot in the air, sending everyone into an immediate panic. JOHN Alright folks, this is a robbery. Nobody moves - yadda, yadda, yadda... Ringo jumps over the teller wall and starts stuffing bills into a bag. As John and Paul cover the crowd, George goes to the corner office and puts a gun to the BANK MANAGER'S head. GEORGE The safe. Let's go. BANK MANAGER Okay, just don't hurt anyone. GEORGE Yeah, yeah, yeah. George leads him out by the collar. CRASH - Titan smashes through the window and lands in a bold superhero stance with hands on hips. TITAN Well, boys, there's no need for all this just to get the free toaster. Paul cocks his gun. 56. PAUL What are you suppose to be? We move in for a nice dramatic close up. TITAN Justice. GEORGE Well, justice, suck on this... George, John and Paul open fire on Titan. He just stands there and yawns as the bullets bounce off him. With their guns empty the three just stare at him in amazement. TITAN Now it's my turn. He turns to George. TITAN (CONT'D) Hey, George, here comes the sun. Titan grabs George and throws him into a fluorescent light fixture in the ceiling. Paul tries to run for the door. Titan snatches the collar of his jacket. TITAN (CONT'D) Say, Paul, your mother should know...that you're a scumbag. He tosses Paul out the window and into a parked DELIVERY TRUCK. Titan turns around just as John hits him with the butt of his shotgun. It instantly breaks apart in his hands. Titan lifts him like a rag doll up into the air. TITAN (CONT'D) John, all you need is love... He throws John who lands on top of a cubical wall - GROIN FIRST. TITAN (CONT'D) ...and a good urologist. 57. Titan effortlessly hops over the teller wall to find Ringo cowering on the floor. He grabs him by the shirt and lifts him up. HAL Well, Ringo...um...um...you're under arrest. EXT. BANK - DAY Titan walks out of the bank with Ringo and George under his arm. He's suddenly swarmed by a group of television reporters, including Roxanne. Across the street is Pat Morita. He watches Titan's first news conference with great anxiety. BANK MANAGER (to Hal) On behalf of the First National Bank of Metro City, I'd like to offer you a reward for your act of bravery. He hands Titan a check. TITAN (reading) Ten thousand dollars! Titan looks over to Pat, who violently shakes his head no. TITAN (CONT'D) (unenthusiastically) I...can't except this. Law and order is it's own...um...reward. Pat gives him the thumbs up. Pat turns, suddenly seeing Roxanne with her camera crew. Captivated, his eyes lock on her. Meanwhile, Roxanne and her cameraman, SETH, are maneuvering around the crowd to get closer to Titan. BRAD HELMS (O.S.) Not so fast, Roxanne. They both turn to see Roxanne's reporter rival Brad Helms, Geraldo without the class, and his cameraman, FRANK. BRAD HELMS This story's mine. 58. ROXANNE Listen, Brad. We were just in the area. I was just trying to - BRAD HELMS I've been in this business long enough to know pretty well what you were "just trying to do." Besides, I heard you couldn't take the big game anymore and were put on fluff detail? Dejected, Roxanne turns and motions for Seth to turn the camera off. SETH You're not gonna take that from him, are you? ROXANNE He's right. Old habit, I guess. (to Brad) We'll get out of your way. As they walk off, Brad makes a comment to Frank loud enough for her to hear. BRAD HELMS Besides, I'm sure there's a pancake supper somewhere that needs covering. INT. ABANDONED METRO CITY LIBRARY - OFFICE - DAY ON TELEVISION We see the news conference on the bank's steps. In the corner of the screen is written: "recorded earlier." BRAD HELMS For months now, since the death of Uberman, the citizens of Metro City have been holding out for a hero. Well, it appears they won't have to hold out for much longer as a new costumed crusader has suddenly stormed onto the scene. Today, at the Metro Savings and Trust, a masked mystery man single-handedly defeated "The Fab Four Gang." Just who is this new caped avenger? Brad holds the microphone to Titan's face. 59. BRAD HELMS I'm sure all of our viewers are now wondering, what's the "T" stand for? TITAN It's a message to all the scum out there. Uberman may be gone, but Metro City has a new protector, and his name is "Tighten!" Another reporter leans in. REPORTER How do you spell that? We PULL BACK to see Plato and Da Vinci watching this spectacle. Master Mind is sitting with them, reading a NEWSPAPER. MASTER MIND (reading paper) Oh, for heaven's sake. I can't believe it. He misspelled his name. Master Mind holds up the newspaper. The headline reads "Metro's New Hero: Tighten." MASTER MIND (CONT'D) No matter, I suppose. Master Mind throws the paper on the floor and begins to pace around the room with his arms folded behind his back. MASTER MIND (CONT'D) We've now fully established Titan as Metro City's hero. They will love him just as they loved Uberman. Everything is going according to plan. Einstein leans over and whispers in Plato's ear. EINSTEIN (whispering) Yeah, if the plan is getting us in jail. Master Mind turns around, facing Einstein. He walks over, standing face to face with the rebellious henchmen. 60. MASTER MIND You know, Einstein, maybe I should have called you Socrates. He also didn't know when to keep his thoughts to himself. EINSTEIN I just fail to see the point in all of this. I mean, why are we creating another superhero when it was such a pain in the ass for you to get rid of the other one? I mean, Uberman is destroyed, we should be using this opportunity to...to... MASTER MIND To what? EINSTEIN I don't know. To take over the weather, space, the world - whatever super villains are SUPPOSED to do. MASTER MIND The reason someone like you will always be a minion is because you have no foresight. We take over the earth, like you said. Then what? Women? Cars? Money? Even the grandest treasures will lose their lustre if you don't have someone to hold them over. Einstein throws up his hands. He's had enough. He pulls off his wig and throws it to the floor. EINSTEIN That's it! This balance of the force bullshit is getting way too Oprah for me. I'm blowing. Who's with me? MASTER MIND You dare? EINSTEIN Yeah, I dare. I'm sick of wearing stupid costumes, and I'm sick of working for a super villain who's turning into a softie. 61. Plato and Da Vinci's mouths drop to the floor. They turn to Master Mind for his rebuttal. MASTER MIND What - did - you - call me? EINSTEIN You heard me. You used to be an inhuman monster, now look at you. You're creating super heroes, you don't go with us on robberies anymore, it's been days since you threatened anyone, oh, and not to mention this Roxanne Ritchi thing. MASTER MIND THAT is none of your business, knave! EINSTEIN Hey, you guys haven't sealed the deal yet, have you? MASTER MIND Silence! EINSTEIN (In a woman's voice) Oh, Master, your head is so big. MASTER MIND I'm warning you, Einstein. EINSTEIN (In a woman's voice) Take me! MASTER MIND I said silence! With his metal gauntlet Master Mind grabs Einstein by the throat and lifts him into the air. Einstein looks frightened as he tries to pry himself free of Master Mind's grip. Master Mind's eyes soften as if his heart is suddenly not into what he's about to do. He let's Einstein drop to the floor. MASTER MIND (CONT'D) Get out of my sight. 62. EXT. RESTAURANT - NIGHT Roxanne and John Cusack are eating on the outside patio of a fancy restaurant. ROXANNE Don't get me wrong, I love being a reporter. I don't think I could do anything else. It's the consequences of what we do that I'm having a problem with. He listens intently as he refills her glass with wine. "JOHN CUSACK" That's where journalistic responsibility comes in, no? ROXANNE It's supposed to. "JOHN CUSACK" Sounds to me like you're running from something. ROXANNE I got someone I cared about killed. If it wasn't for me, he wouldn't have been involved. John suddenly gets a disturbed look in his eye, realizing what she's talking about. He reaches across the table and takes her hand. "JOHN CUSACK" You can't blame yourself. My father used to say each of us must answer the great call to truly feel alive. ROXANNE Was he an actor? "JOHN CUSACK" ...No. He was...a landscaper. And a horrible one. I mean he would fail time and time again at his...landscaping. And sometimes he'd get pretty beaten up or thrown in jail - ROXANNE Jail? 63. "JOHN CUSACK" My point is he took the good with the bad. He grew a little each time. Improved, learned. ROXANNE Was he ever successful? "JOHN CUSACK" God, no...but don't let deter you. Roxanne LAUGHS. ROXANNE Thanks for this. You know, this is embarrassing, but it's been a long time since I - It's starting to lightly sprinkle. Roxanne looks up. ROXANNE (CONT'D) I think it's starting to rain. We might want to find a table inside. "JOHN CUSACK" What were you gonna say? ROXANNE Oh, I was gonna say...It's been a long time since...well, I've been with someone I...enjoy being with. John Cusack smiles warmly and raises his glass for a toast. "JOHN CUSACK" To people who enjoy being with each other. They go to clang glasses, when the rain suddenly causes John Cusack's disguise generator to short. His true form of Master Mind is briefly revealed to Roxanne as a BOLT OF ELECTRICITY encircles his body. Roxanne drops her glass and jumps out of her seat. MASTER MIND (CONT'D) Oh, no. Don't look at me. LIKE A BROKEN TV the image keeps switching between MASTER MIND AND JOHN CUSACK. 64. As Master Mind starts to franticly slap at his watch, the Cusack disguise begins to hold steady. He nonchalantly returns to cutting his steak. "JOHN CUSACK" Okay, never mind that. Now, where were we? Roxanne grabs his glass and throws the drink in his face, causing the generator to short out permanently. Master Mind now sits in his true blue form. ROXANNE Oh my God. MASTER MIND You're not gonna get all freaky about this, are you? ROXANNE This...this is too much, even for you. God, I go out with you, tell you my innermost thoughts. MASTER MIND I only did this because I wanted to talk to you on the same level. You know, without all the baggage? ROXANNE Baggage? You burned my boyfriend alive, you sick son-of-a-bitch! MASTER MIND You see, that's exactly what I'm talking about. Roxanne starts to walk away. MASTER MIND (CONT'D) Roxanne! ROXANNE Stay away from me. Master Mind sinks back down to his chair. Despite the now heavy rain bombarding him, he returns to his food. Several resturaunt patron's are looking at him through the window. 65. Our villain turns to them, giving them a villainous glare. MASTER MIND What? INT. MASTER MIND'S BEDROOM - NIGHT Master Mind is lying on his back, wide awake. MASTER MIND (mumbling to himself) Stupid. What was I thinking? Plato, it's his fault. He's the one who sent me on this weak-willed path. I'll filet his scrotum for this. Me, a creature of evil, in love with Roxanne Ritchi. Preposterous. I hardly give such matters thought He rolls onto his side. He yawns and closes his eyes. Suddenly, they shoot back open. CUT TO: EXT. ROXANNE'S APARTMENT - NIGHT Master Mind pulls up in a blue Rolls Royce, across the street from Roxanne's apartment He stares up at the building, hoping to catch a glimpse of her. Finally, she appears, primping her hair in her apartment window's reflection. MASTER MIND I should just go up there and just lay it all out to her. "Roxanne, I like you - I always have. Oh, and I'm sorry I blew up your ex. (realizing the absurdity of his words) Yeah, that would go over like a pants-less clown at a child's birthday party. What the hell am I even doing here? Who cares what she thinks? I'm a supervillain and here I am acting like a love struck schoolboy. Forget this. I control my own destiny! 66. He turns the ignition key - NOTHING HAPPENS. He repeats but gets the same results. MASTER MIND (CONT'D) (disgusted) Perfect. INT. ROXANNE'S APARTMENT - NIGHT She pulls a pack of smokes off her night stand. Empty. ROXANNE Damn. She grabs her long coat and throws it over her robe. EXT. ROXANNE'S APARTMENT BUILDING Roxanne steps outside. ROXANNE Please be open. Across the street is a liquor store. The light is still on. ROXANNE (CONT'D) Thank God. She walks across the street, passing in front of Master Mind's car. Spotting her, he sinks down in his seat. Roxanne walks by, totally unaware of his presence. Relieved, Master Mind sits back up and watches her go into the store. INT. LIQUOR STORE - NIGHT Roxanne walks up to an elderly Korean SHOPKEEPER at the counter. ROXANNE A pack of Lady Strikes, please. EXT. MASTER MIND'S CAR - NIGHT Master Mind is talking on his cell phone. MASTER MIND Hello, Triple A? 67. He suddenly spots something across the street. EXT. LIQUOR STORE - NIGHT A HOODLUM walks up to the entrance of the store and pulls out a gun from under his coat. EXT. MASTER MIND'S CAR - NIGHT Master Mind stares in shock. MASTER MIND I'll call you back. He hangs up the phone and watches the Hoodlum go inside the store. INT. LIQUOR STORE - NIGHT The Hoodlum reaches across the counter and grabs a fist full of cash from the register. SHOPKEEPER Hey! SHOTGUN HOODLUM Shut up, Gramps. He turns to Roxanne, spotting a GOLD NECKLACE around her neck. SHOTGUN HOODLUM (CONT'D) Gimme that necklace! ROXANNE I don't think so. The Hoodlum cocks his shotgun. SHOTGUN HOODLUM I said give it to me! MASTER MIND (O.S.) The lady said no. The hoodlum turns around to see Master Mind in the doorway holding a STRANGE-LOOKING HAND CANNON (GOO GUN) with knobs and blinking lights. The hoodlum starts to laugh. 68. SHOTGUN HOODLUM What the hell's that? A super soaker? MASTER MIND No, it's a goo gun. The hoodlum turns his gun to Master Mind. SHOTGUN HOODLUM Yeah, what's it do? MASTER MIND It goos. Master Mind fires the cannon. It instantly covers the store in a cloud of SMOKE. The smoke clears to reveal the hoodlum STUCK TO THE WALL, covered in a thick, GREEN GUNK. Roxanne stares at him, dumbfounded. MASTER MIND (CONT'D) It's...a prototype. Master Mind starts to walk out when he's suddenly confronted by the shopkeeper. SHOPKEEPER I know you! You Master Brain guy. You a hero. Master Mind points the goo gun at him. MASTER MIND Don't - EVER - say that again. EXT. LIQUOR STORE - NIGHT Master Mind walks out with the cannon resting on his shoulder like he's a short timer in Da Nang. Roxanne follows shortly behind him. ROXANNE Hey! Master Mind turns around. ROXANNE (CONT'D) Are you following me or something? 69. MASTER MIND Don't flatter yourself. He turns away and continues walking. Roxanne runs in front of him blocking his way. ROXANNE Don't walk away from me when I'm talking to you. Finally it occurs to her what's going on. ROXANNE (CONT'D) What a minute...all that stuff you use to say to me when Uberman was alive - about me being the loyal queen by your side as you rule over Metro City. That wasn't just super villain rhetoric, was it? You actually meant it! MASTER MIND My, someone has a rather high opinion of themselves. They stare at each other in silence, their glares locked in conflict. ROXANNE (coldly) Do you really think I would be with someone like you? This stings Master Mind to the bone. And after a brief contemplation, he reaches the only logical, painful conclusion. MASTER MIND No. With that, Master Mind exits into the night, leaving Roxanne with a baffled expression on her face. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind enters in a huff. Da Vinci closes the door behind him as Plato notices his master's agitated state. PLATO Everything alright, sir? Master Mind GRABS PLATO BY THE GROIN with his metal gauntlet causing Plato's eyes to bulge in pain. 70. MASTER MIND (overly calm) Fine, why do you ask? PLATO You...just...seem... Master Mind tightens his grip. MASTER MIND Go on. PLATO ...distracted. Master Mind releases him. MASTER MIND Just with business, my minion. Just with business. I've decided it is time. PLATO You mean? MASTER MIND Yes, we've created our hero, now it's time to give him a little motivation. DA VINCI How do we do that? MASTER MIND To be simply good is not enough. A hero must be driven by an almost relentless desire to right a wrong that can never be corrected. PLATO You mean? MASTER MIND Yes, he must lose someone near and dear to him - his father figure. Gentlemen, it's time for Operation Mentor Kill! EXT. SKY OVER METRO CITY - DAY Titan flies high over and through the city, under bridges, between buildings, etc. He's not really working, just enjoying himself. 71. INT. WOMAN'S APARTMENT - NIGHT A PRETTY WOMAN sits at her makeup table wearing nothing but her bra and panties. Through the reflection in her mirror we see a large window directly behind her. As she applies lipstick we see Titan fly quickly by in the background. After a moment he slowly slides back in view and begins ogling the girl. She sees him in the mirror and quickly covers herself with a robe. Titan tries to hide his face as he zooms off. MOMENTS LATER Titan looks down to see an APARTMENT BUILDING IN RUIN. Emergency lights flash around it as swarms of people run around in chaos. TITAN Man, what the hell happened down there? Wait a sec - He stops in mid-air as he comes to the striking realization. TITAN (CONT'D) THAT'S MY APARTMENT!!! EXT. HAL'S APARTMENT BUILDING - DAY Titan lands in front of the rubble that was once his home. Reporters stand just beyond the police line. TITAN Crap. From the wreckage crawls a dying Pat Morita. TITAN (CONT'D) PAT! Titan goes and kneels beside Pat, holding him in his arms. TITAN (CONT'D) You okay? "PAT MORITA" I'm dying, kid. There is just one last lesson I have for you. It is the most important of all. 72. TITAN What's that? "PAT MORITA" Master Mind did this, you must avenge me. TITAN Master Mind? Why? "PAT MORITA" Because he's evil. You must stop the evil Hal - stop the... Pat's body goes limp. The cameras begin to pop and flash around them. Titan gently lays Pat's body down and stands respectfully over him. The reporters rush over. REPORTER 1 Tighten, Is this the work of Master Mind? REPORTER 2 How will the death of your mentor affect your resolve? REPORTER 3 Was that Pat Morita? Titan walks up to one of the cameras. TITAN This injustice will not go unpunished. Master Mind, if you can hear me, Tighten is coming for you. In the background we see Plato and Da Vinci, DRESSED AS PARAMEDICS, load pat's body onto a stretcher. PLATO ACCIDENTALLY DROPS HIS SIDE. As he bends down to pick it back up, Pat quickly slaps him, then goes back to playing dead. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind and the boys prepare the fortress for Hal's revenge attack. Master Mind is as giddy as a schoolboy. 73. MASTER MIND Alright, people, we don't have much time. Titan should be here any minute, so let's get the lead out. There is a GIANT MOUNTED DEATH RAY in the middle of the hall being tinkered with by Da Vinci. MASTER MIND (CONT'D) How's the death ray coming? DA VINCI Nearly up to full power, sir. MASTER MIND Hum. Let's turn it down a few notches. It's his first time and we don't want to get in a lucky shot, now do we? Plato enters the room. MASTER MIND (CONT'D) Anything on the radar yet? PLATO Not yet, sir. MASTER MIND I see. Well, he must be planning something big. Are the flame androids deployed? PLATO All twelve. Master Mind rubs his hands in anticipation as he sits down on his throne. MASTER MIND Wonderful, wonderful. Plato, Da Vinci, take your places next to me. They move to either side of the chair. MASTER MIND (CONT'D) No slouching. Da Vinci straightens up and sucks in his gut. They remain this way for several long moments. Master Mind occasionally glances at a DIGITAL CLOCK on the wall. Still no Titan. 74. LATER Apparently quite some time has passed. The bold stances have degraded to fatigue. PLATO He's certainly taking his time. MASTER MIND He'll be here. That's the way it works. STILL LATER Master Mind reclines in his chair and taps his metal gauntlet impatiently on the armrest. Plato has squatted down, resting his chin on his hand. MASTER MIND (CONT'D) Unprofessional, that's what this is. No, it's disrespect for the craft. Master Mind rises and begins to pace back and forth. MASTER MIND (CONT'D) Would Uberman have kept us waiting like this? Of course not. He was a pro who knew the score. It's time we spelled out a few things for this Titan. I will not be made a fool of. He storms out of the room. INT. HAL'S NEW APARTMENT - DAY Titan's sitting on the floor in a barren apartment wearing his costume top and some tighty whities. He sips his beer as he watches a basketball game on a tiny TV. Much to his annoyance, there's a KNOCK at the door. TITAN Oh, for crying out loud. He gets up and opens the door. It's Master Mind. MASTER MIND Do you know who I am? 75. It takes a few moments to register, but Titan's suddenly excited. TITAN Yeah, you're Master Mind. Yeah! You're actually the guy I want to see! MASTER MIND Oh, so NOW you want to get down to it. Well, I want to get a few things off my chest first. Master Mind walks past Titan into the apartment. He spins around, pointing at him accusingly with one of his metal fingers. MASTER MIND (CONT'D) Of all the inconsiderate - Do you have any idea how long we waited for you? We're you even planning on coming to me and getting revenge? Titan shuts the apartment door, and turns back toward his guest. TITAN Well, at first I was going to. You know, because that's what I figured I was supposed to do. But then I got to thinking- MASTER MIND (interrupting) -You got to thinking? There's nothing to think about. I'm the villain. I do something bad, you come and get me. TITAN - I got to thinking...what's the point? Master Mind throws up his hands. MASTER MIND Maybe you're right. What's the point? He suddenly notices something in the corner of his eye. He walks over to a futon in the living room. On top of it is a LARGE SACK OVERFLOWING WITH GOLD WATCHES,RINGS AND OTHER VALUABLES. 76. MASTER MIND (CONT'D) What are these? TITAN That's what I wanted to talk to you about. MASTER MIND (baffled) Where did you get all this? TITAN (proudly) Get this: I stole them. MASTER MIND From where? TITAN From all over. You see, once you killed Pat and ruined my other apartment building I was pretty pissed off, so I figured I'd go, find you and kick some ass. Then I thought to myself: "Okay,then what?" I mean, if we were to fight, what would I get out of it? Would I get my apartment back? Would I be able to pay the bills? MASTER MIND Well, what about your mentor? TITAN Tell you the truth? He was kind of a dick. I mean, being a hero is dandy and all, but it's volunteer work. Now you've always had the right take on all this. I mean, when you rob a bank or take over the diamond exchange you get something out of it. I mean, when you don't get caught, which, no offense, isn't very often. And that brings me to what I wanted to propose to you: Who could catch you if I'm by your side? Perplexed by his proposal, Master Mind just stares at Titan awe-struck. MASTER MIND You want to team-up? 77. TITAN You got the brains, I got the brawn. We could even call ourselves that: `Brain' and `Brawn'. Look at this. Titan picks up a piece of POSTER BOARD off the floor and shows it to Master Mind. TITAN (CONT'D) I even designed us some new costumes. The picture is crudely drawn with magic markers and crayons. A big headed man (Master Mind) is standing on a plate of grass in a blue costume with a picture of a brain on his chest. Next to him, is a picture of Titan in a red costume with a black cape, but his chest is mysteriously blank. Titan proudly points to the two figures. TITAN (CONT'D) See, you'd be brain, so you got a little one on your costume, and then I'll have brawn on mine...once I figure out the best, you know, visual interpretation of it. What do you think? MASTER MIND What do I think? Master Mind shakes his head tiredly. MASTER MIND (CONT'D) I think you're probably the biggest idiot I've ever met. I mean, I can't believe you. All your gifts, all your powers, and all you want to use them for is your own financial fulfillment. You know what? Your kind of people make me sick. Titan puts down his drawing. TITAN I worked hard on this. MASTER MIND Oh - gee - I am so sorry! 78. Master Mind looks to Heaven in disgust. MASTER MIND (CONT'D) (under his breath) Of all the people to pick, it had to be this loser. This strikes a cord with Titan. TITAN Now, hold on. You're going a little too far. MASTER MIND I wish your mother said that to your father the night of your conception, they would have saved me a whole lot of heartache. TITAN Hey, I mean it. Master Mind gets right in his face. MASTER MIND Oh, yeah? What are you gonna do? EXT. HAL'S APARTMENT BUILDING - DAY We see Master Mind's body CRASH through the building and land in a DUMPSTER across the street. A car pulls up. The driver's door opens. Da Vinci gets out and runs to help his master. DA VINCI Master! MASTER MIND (O.S.) It hurts. Da Vinci peeks into the dumpster to see Master Mind's body cushioned by a stack of trash bags. DA VINCI What hurts? MASTER MIND It! The overly large henchmen starts to pull his master from the dumpster when they suddenly hear a voice from above. It's Titan peeking through the hole in his apartment wall. 79. TITAN I don't need you, I don't need anybody. I have the power to do and take anything I want. And now, I'm gonna take back everything this city owes me. Beware Metro City, it's time for Titan to collect. Titan shoots up into the air. TITAN (CONT'D) Oh, and from now on - I'M GONNA FLY THE WAY I WANT TO FLY! He takes a sitting position and flies away as if he were piloting an invisible jet. Master Mind climbs out of the dumpster and watches Titan disappear into the distance. DA VINCI How'd the plan go, boss? MASTER MIND I just made myself redundant, old friend. Da Vinci gives Master Mind a whiff. DA VINCI It's not that bad. INT. BANK - DAY Titan, with a happy bounce in his step, enters the bank. The last time he was here he thwarted a robbery. He looks nostalgic. A SECURITY GUARD shyly walks up to him like a kid meeting his TV idol. SECURITY GUARD Morning, Tighten. TITAN Morning. SECURITY GUARD Is there something we can do for you? 80. TITAN Oh, don't bother about me. I'm just here to make a withdrawal. Titan walks across the lobby, drawing stares of admiration from all. A little girl waves to him sweetly. He gives her a good- natured WINK as he heads straight for the vault. The security guard watches him enter and come out with a SACK OF CASH. Sure he must be misunderstanding what's going on, the security guard just stares at Titan as he passes by and out the door. The bank manager comes over to the guard. BANK MANAGER Say, did he just rob us? SECURITY GUARD Not sure. Sort of looks it, don't it? BANK MANAGER Yeah. SECURITY GUARD Should I, you know, stop him? BANK MANAGER Umm...Yeah. As the security guard exits the bank, the manager stares out the window. His eyes suddenly grow wide with terror. The guard's body suddenly smashes through the window, landing at the startled bank manager's feet. BANK MANAGER (CONT'D) (looking down at the guard) He did rob us, didn't he? CUT TO: TELEVISION "A Channel 7 News Special Report." Brad Helms wipes into view. 81. BRAD HELMS "Absolute power corrupts absolutely." When Lord Acton stated that, in a letter to Bishop Mandell Creighton in 1887, no one thought much about it, but today Metro City is reeling from that very prophecy. Tighten, who many thought of as our savior, has turned his back on the cause of justice. CUT TO: TITAN BEING EVIL - MONTAGE EXT. DIAMOND EXCHANGE - DAY Titan flies through the window of the building. He emerges seconds later laughing with his shirt full of booty. EXT. CITY STREET - DAY A woman screams from the window of a BURNING BUILDING. Titan flies up to her, grabs her fur coat and zooms off again, leaving the woman behind, slightly confused. EXT. OUTSIDE MARKET - DAY Titan steals a little boy's lollipop and gooses his mother. EXT. CITY STREET - DAY Dozens of people run through the streets apparently to get out of a downpour. We cut to the top of a building and see Titan ZIPPING UP HIS PANTS and laughing. INT. ABANDONED METRO CITY LIBRARY - NIGHT Master Mind paces back and forth in front of Plato and Da Vinci. PLATO I don't understand it. He seemed to have every characteristic we were looking for in a superhero. MASTER MIND Well, there's no use crying about it now, we must take action. I'm not going to play second fiddle to that crass buffoon. We must destroy Tighten. 82. PLATO It won't be easy. Uberman had a sense of decency and genuine love for the people. That was his weakness and was easily used against him. MASTER MIND Yes, but he possesses the same flaws present in Uberman's DNA - copper. It's like Benjamin Franklin always said: "If something works don't dick with it." EXT. BAR - DAY It looks like a war zone passed through here. Smashed police cars and debris lay everywhere. This seems to be the only building left untouched. INT. BAR - DAY A very tipsy Titan is sitting at the bar, looking deep into the bottom of his beer glass for answers. TITAN I can have anything I want. I'm like a god. The BARTENDER just listens as he wipes down a glass with a dirty rag. TITAN Point to any woman in this bar. I could have her in a second. He follows the bartender's gaze to THE ONLY OTHER PERSON THERE - A passed out, MIDDLE AGED HAG OF A BARFLY. TITAN (to Old Barfly) Hey, you wanna get with this? BARTENDER Buddy, what do you want? Titan carefully considers this for a moment. TITAN What do you want? That's the question, isn't it. I mean, what do you want when you can have everything? (MORE) 83. TITAN(cont'd) I suppose what I really want is to never be forgotten again. I want to do something that can never be cast aside or one-upped. I want a - what's it called? - A legacy. I want a legacy. Yeah, that's it. I like the sound that. BARTENDER I meant, what do you want to drink? TITAN Oh. EXT. BAR - LATER Titan stumbles out of the bar, carrying a large sack of money. MASTER MIND (O.S.) Your time has come to an end, Titan! He looks up to see Master Mind suddenly standing before him. TITAN What? MASTER MIND There can be only one master criminal in this city - and it's me. TITAN Really? Titan melodramatically throws up his arms. TITAN (CONT'D) I guess I should leave town then, huh? MASTER MIND I have a better idea - NOW! Two floors up Da Vinci releases a rope. A COPPER CAGE, like the one that caged Uberman, drops down on top of Titan. Titan nonchalantly surveys the cage. He walks to the bars, tries to pull them apart but can't. MASTER MIND (CONT'D) That's copper my good man. Your one weakness. (MORE) 84. MASTER MIND(cont'd) For all your amazing gifts of brawn you are no match for my intellect. Titan thinks for a moment. Suddenly, he starts to SPIN like a human top, DRILLING HIMSELF INTO THE STREET BELOW. As he disappears beneath the surface, we see a shocked look on Master Mind's face until Titan suddenly explodes out from under the street in front of him. Master Mind stares up at him, dumbfounded. Titan makes like he's going to strike him down, but stops. TITAN You know what? You're nothing but a bug. Not even worth my effort. He turns his back to Master Mind and continues down the street. Plato makes his way from the shadows to join his master. They watch Titan shrink into the distance. MASTER MIND He's not as dumb as I thought. PLATO I guess not...Funny, though. MASTER MIND What's funny? PLATO Funny Uberman didn't think of the same thing. EXT. HIGH ABOVE METRO CITY - DAY As Titan flies, he looks down at the rooftops of the city below. Suddenly, something catches his attention. HAL That's it! He stops, hovering in place as he looks down below. The buildings, which make up the heart of downtown Metro, are in a PERFECT TRIANGLE with a long strip of street leading up to it. It sorta looks like a bowling lane. 85. HAL Hello, Legacy. EXT. KINGPIN BOWLING - DAY Vinnie and his goons come running out as the hear a COMMOTION. They look up to see Titan ripping off THE GIANT BOWLING BALL from the top of the establishment. VINNIE Hey, that's my ball! INT. ROXANNE'S APARTMENT BUILDING - DAY Roxanne enters the building's elevator. Just before the door closes an ELDERLY WOMAN slides in. ELDERLY WOMAN That was a close one. Sixth floor, please. Roxanne smiles and goes to press the button. The elderly woman suddenly pulls out a SPRAY CAN, shooting a MYSTERIOUS-LOOKING MIST into Roxanne's face. She falls to the floor unconscious. INT. ROXANNE'S APARTMENT - DAY Roxanne awakens, finding herself tied to a chair in her living room. We hear NOISE from a TV in the background as she tries to adjust her vision. Slowly, the blurry figure before her becomes clear. It's Master Mind. He sits on her Lazy-Boy, reading what looks to be some kind of JOURNAL. MASTER MIND Wow, I always thought Uberman was your first superhero - but it looks like our little Roxanne dated a linebacker in college. ROXANNE That's my diary. MASTER MIND So it is. 86. ROXANNE It's personal. MASTER MIND Well, then I wouldn't leave it in your underwear drawer for just anyone to find. He throws the diary over his shoulder. ROXANNE What do you want? MASTER MIND I need your help. ROXANNE So you knock me out and tie me to a chair? MASTER MIND You're not going to like what I'm about to tell you. As she tries to shake off her headache from being knocked unconscious, Roxanne spots something on the TV. ON TELEVISION Brad Helms is huddled behind a van. BRAD HELMS It's chaos here in city square as city police - Behind him, Titan picks up a POLICE CAR and throws it at a PADDY WAGON. Both vehicles EXPLODE on impact. BACK TO SCENE ROXANNE He's really out of control. MASTER MIND Tell me about it. As if finally realizing something, Roxanne looks back at Master Mind. ROXANNE I should have known. You have something to do with this, don't you? - With Titan turning evil. 87. MASTER MIND Well, the evil thing he did by himself. My goal was to give MYSELF purpose by creating an intellectual sparring partner. ROXANNE (confused) You're talking like you made him. MASTER MIND And they call me Master Mind. ROXANNE Let me get this straight. You missed getting your ass kicked, so you made a new guy to kick your ass. That's pathetic. MASTER MIND In hindsight... Roxanne turns back to the TV to see a group of POLICE OFFICERS open fire on Titan. The bullets just deflect off his chest. ROXANNE And his powers, they're just like Uberman's. Why would he have his powers? MASTER MIND (almost ashamed) I had some left over from something. I infused him with it. ROXANNE YOU DID WHAT!? Driven by rage, she struggles to tear out of her bonds. She finally relents, giving Master Mind a look fueled by pure hatred. MASTER MIND Yeah, that's why I decided to tie you up. ROXANNE You did all this because you wanted purpose? MASTER MIND He seemed nice. 88. TELEVISION Titan is standing on top of a destroyed police car. He waves for the camera to zoom in on him. TITAN Closer. I want to show the people my real face. He pulls off his mask, revealing himself as Hal Stewart to the public for the first time. TITAN (CONT'D) Recognize me? BACK TO SCENE ROXANNE Hal Stewart. He's the guy we thought saved that woman and kid. Turned out he was just trying to save his own ass. MASTER MIND Yeah, good to know - NOW! TELEVISION Titan throws the mask over this shoulder and hops off the car. TITAN That's right, I'm really Hal Stewart. Former hero and bowling teacher at Kingpin's Bowling. BACK TO SCENE Roxanne turns to Master Mind, condescending him with her eyes. ROXANNE You picked a bowler to give super powers to? MASTER MIND It's a modest profession! TELEVISION 89. TITAN With my new found power, I've recently started to wonder what sort of legacy I should leave. Should I be a hero? I tried that once before - even saved a lady and her baby from being squashed. I was treated like a god until everyone started to shit on me - Okay, so what if I didn't "purposely" save them! He walks over and puts his hand on a large circular concrete shape just off camera. TITAN Well, I'm going to make something that can't be taken away from me. I'm going to create a permanent monument to my greatness. One that won't be so easily forgotten or erased. The camera pulls back revealing THE GIANT CONCRETE BOWLING BALL from Kingpin's. TITAN I intend to create a new category in the Guinness Book of World's Records by rolling the biggest strike in the history of bowling. He grabs the camera and points it to the DOWNTOWN BUILDINGS. We realize they are PERFECTLY ALIGNED IN BOWLING PIN FORMATION. TITAN My thanks to the city planning commission. This wouldn't have been possible without them. Titan grabs the camera so it's pointing back at him again. TITAN Tell your friends and family to tune in right here to this station at noon tomorrow. BACK TO SCENE ROXANNE My god, he's nuts. That'll destroy the whole business triangle. 90. Master Mind seems to be contemplating something - something bad. ROXANNE What? MASTER MIND My lair is in the direct path of the ball. ROXANNE Oh, real nice. Wouldn't want anything to happen to your hideout, would we? MASTER MIND You don't understand. I have certain equipment that's - that's highly unstable. ROXANNE What do you mean? MASTER MIND I sort of have a hydrogen reactor, okay? ROXANNE A HYDROGEN reactor? MASTER MIND It's experimental - only one in the world...Well, how do you think I power all my inventions? Someone like me can't pay for electricity. The bills would be outrageous. ROXANNE A REACTOR? MASTER MIND It creates 100 times the output of a nuclear one...If destroyed it could... ROXANNE - Vaporize the entire city! MASTER MIND (proudly) Pshaw...the whole eastern seaboard, actually. That little baby is amazing. I'm quite proud of it. (MORE) 91. MASTER MIND(cont'd) (off her deadpan reaction) I mean...we'd better find a way to stop him. Master Mind thinks a moment. MASTER MIND Did Uberman have a hideout? ROXANNE What? MASTER MIND A cave, a solitary fortress of some kind. C'mon, all heros have a place to hang their capes up in. Roxanne, it may be our only chance to find something, a clue, anything that could give us a fighting chance. ROXANNE It's under his house. MASTER MIND Whose house? Roxanne can hardly believe what she's telling him. ROXANNE Wayne Scott's. Master Mind shoots up out of his chair. MASTER MIND Wayne Scott? Uberman was Wayne Scott!? Wayne Scott, the wealthy philanthropist? But he disappeared - ROXANNE (interrupting) He disappeared just over two months ago when you killed him. Not only did you rid the world of a hero, you killed a kind, noble, generous man. Perhaps ashamed, the super villain hangs his head. Master Mind walks behind Roxanne and undoes her bonds. Rubbing her wrists, she watches him as he walks over to the door. 92. ROXANNE (CONT'D) Looks like you got what you always wanted. Uberman is out of the picture and Metro City is doomed. He grabs the door knob and stops, considering her words. MASTER MIND "Metro City doomed." You know, I never thought I'd say something like this, but here it goes - He slowly turns to her, CUE HEROIC MUSIC. MASTER MIND (CONT'D) Not if I have anything to say about it. EXT. WAYNE SCOTT'S MANSION - NIGHT Master Mind stands before the huge, Gothic structure in awe. MASTER MIND Such a dark place for one such as you. I wonder, underneath your noble deeds, what inner demons drove you to your endless crusade for justice? He walks to the front entrance. The double doors have been sealed shut with boards and nails. Master Mind begins to tear them off with his metal hand. INT. WAYNE SCOTT'S MANSION - NIGHT The doors opens. A beam of moonlight immediately pierces the darkness, forming an illuminated path into the heart of the manor. Master Mind enters. Covered in dust and cobwebs, the hall looks like a gigantic crypt. MASTER MIND Good lord, man. You've only been dead for two months. Master Mind walks, coming to a gigantic painted PORTRAIT OF WAYNE SCOTT. He stops to reverently admire the image of his fallen foe. 93. MASTER MIND (CONT'D) A disguise so simple, it's ingenious. No wonder I never caught on. Besides the Armani suit, there's nothing to hide the fact that this is the same person as Uberman. In the picture, he's even standing in the same cheesy, heroic pose with his fists on his hips. MASTER MIND (CONT'D) Two lives, yet in both you were an ideal. Perhaps it was you who was victorious in the end, old friend. A BONGING sound suddenly bellows through the dark halls. Master Mind comes to a grandfather clock standing next to a gigantic BOOKCASE. On the twelfth bong it falls silent. Master Mind begins to slide it across the floor until he hears a loud CLICK. The bookcase slides into the wall, REVEALING A HIDDEN PASSAGE. MASTER MIND (CONT'D) I'll miss how predictable you were. The passage way leads Master Mind to a WORKING ESCALATOR. Master Mind gets off the escalator to see a long hallway with stone walls. He begins to hear strange SOUNDS, almost like MUFFLED SCREAMS, coming from a doorway at the end of the hallway. Master Mind starts walking towards it. As he steps closer, he begins to notice a light cracking through the bottom of the door. MASTER MIND (CONT'D) Hello? Anyone here...besides..all the BIG MEN who are with me now? Nothing. MASTER MIND (CONT'D) (to himself) What's the worst you're gonna find? (MORE) 94. MASTER MIND(cont'd) The man was a boy scout, not a serial killer. He opens the door to his immediate amazement. It's some kind of screening room. A PROJECTOR shoots an image onto A DIRTY WHITE SCREEN hanging on the wall. BEER CANS litter the floor; a table in front of a ripped-up couch is covered in discarded snack goods; and a Kiss Pinball machine stands in the far corner next to a CLOSED DOOR. Master Mind turns his attention to the action on the screen. SCREEN A woman dressed in a leather DOMINATRIX OUTFIT is whipping an overweight man lying on a swing-like device with his butt sticking out. DOMINATRIX IN FILM YOU ARE A WORM! She whips him three times. The man CRIES out in pain. FAT MAN IN FILM PINEAPPLE!!! PINEAPPLE!!! Master Mind's eyes are transfixed on the disturbing imagery. The door by the pinball machine suddenly swings open. WAYNE SCOTT, dressed in raggedy sweats, steps into the room carrying a CAN OF BEER and a bowl of JIFFY-POP. Master Mind cannot believe his horrified eyes. MASTER MIND Ahhhhhh! Wayne Scott is just as startled. WAYNE SCOTT Jesus! He drop his drink and snack to the floor. The two men stare at each other as they struggle to regain their normal breathing patterns. Wayne Scott walks over to the couch, brushes off a thick layer of chip crumbs, and sits down. WAYNE SCOTT (CONT'D) What the hell are you doing here? 95. MASTER MIND I might just ask you the same question. I had thought I incinerated you. WAYNE SCOTT You scared the bejesus out of me. How'd you figure out I was still alive? Wait, how do you know my identity!? MASTER MIND Roxanne told me. As for your ruse, I forgot to line the bottom of the copper cage - Somebody pointed that out to me recently. Figured if they could do it, so could you. But one thing I couldn't figure out - WAYNE SCOTT The skeleton? Something I "borrowed" from a medical school a few months before. MASTER MIND A few months? How long had you been planning this? WAYNE SCOTT I always planned to retire - eventually. I mean, come on, you can't do this sort of thing in your fifties. You'd just look ridiculous. The pieces of the puzzle appear to be coming together in Master Mind's head. MASTER MIND I see it all so clearly now. INT. MASTER MIND'S HYDROFOIL - FLASHBACK Master Mind and his minions cover their eyes as the observatory explodes. MASTER MIND (CONT'D - V.O.) You must have done it just seconds before the observatory exploded. 96. INT. OBSERVATORY - FLASHBACK Similar to what Titan did, Uberman bores out from under the cage. MASTER MIND (CONT'D - V.O.) You bore out from under the cage. Then, using your Uber-Speed, - EXT. OBSERVATORY - FLASHBACK Running in a blur-like haze, Uberman screeches to a halt in front of some bushes. MASTER MIND (CONT'D - V.O.) - you made your way to safety, where you had the skeleton safely hidden away somewhere. EXT OBSERVATORY - SKY - DAY Uberman soars high above the clouds. He looks down at the observatory, which is a mere speck in the distance. MASTER MIND (CONT'D - V.O) (CONT'D) Then you must have flown to a safe distance and waited for the explosion, then... Just as the observatory explodes Uberman aims and throws the SKELETON like a javelin. It soars through the air like a missile, tearing through the flames of the explosion, and crashing right into the windshield of Master Mind's hydrofoil. END OF FLASHBACK Wayne stares at Master Mind, clearly impressed. WAYNE Man, you ARE smart. MASTER MIND But why fake your death? Why go through all of it? You could have just quit. WAYNE SCOTT But the responsibility would still be there. (MORE) 97. WAYNE SCOTT(cont'd) A cop can retire and stop handing out speeding tickets - but people expect more from superheroes. I tell you, a volcano couldn't erupt in Zimbabwe without everyone expecting me to do something about it. I figured, out of sight, out of mind. MASTER MIND And Wayne Scott? Why did he have to disappear? WAYNE SCOTT Both of my lives have so much baggage. It's time for new baggage, you know? Master Mind's is absolutely flabbergasted. MASTER MIND I just can't believe it. This whole time you've been in hiding while a force of great evil is tearing your city apart? Wayne rises to his feet, waving his hands for Master Mind to say no more. WAYNE SCOTT I don't want to hear about it. That's why I don't have a television in here to remind me of all the things I SHOULD be doing. Hell, I could get a wife to do that. MASTER MIND There's a demented supervillain out there about to destroy our - I mean, your city. Wayne shrugs indifferently. MASTER MIND You're really going to do nothing? WAYNE SCOTT Good and evil have a way of balancing themselves out. If this guy is as bad as you say, somebody will rise up to fight him. It's just the order of things. You found me, didn't you? 98. Wayne puts a condescending hand on Master Mind's shoulder. WAYNE SCOTT (CONT'D) I know it's hard, but you'll find someone else someday. He then starts walking to the door. MASTER MIND You're the only one who can stop him. Wayne turns around. WAYNE SCOTT Couldn't if I wanted to. Gotta a plane to catch. MASTER MIND A plane? WAYNE SCOTT Going to Barbados for a little change in climate. Now, if you'll excuse me, I got to go pack. He reads the still defeated look on Master Mind's face. WAYNE SCOTT (CONT'D) You were a good foe. I'm sorry if I've let you down. If it makes a difference, you were the best foe a hero could ask for. MASTER MIND Not smart enough to come up with a full-proof trap. WAYNE SCOTT Well, you did almost have me when you figured out my weakness was copper. Now that made me sweat a little. Took me way too long to drill out from under that cage. MASTER MIND I got lucky. WAYNE SCOTT Anyway, it's a good thing for my sake that I could always count on you for an out. 99. MASTER MIND (suddenly confused) What do you mean? WAYNE SCOTT C'mon, we always threw each other a couple of bones. You would always leave me an out in one of your `full-proof' traps, and I'd never had you incarcerated at a penitentiary that you couldn't eventually escape from. It kept our little game going. Master Mind seems deflated. MASTER MIND Game? - Was that all this ever was to you? You know, I was trying my best every time I fought you. Those `outs' as you call them were unintentional. WAYNE SCOTT Oh. MASTER MIND I guess I was never really a match for you, was I? Wayne shrugs. MASTER MIND (CONT'D) (thoughtfully) Then how can I expect to be one for Titan? A beaten man, Master Mind heads for the door, but stops and turns around. MASTER MIND (CONT'D) What about Roxanne? Wayne unleashes an exhausted sigh. WAYNE SCOTT I think we both got what we wanted out of our relationship. She got a career out of me, and I got plenty of other things out of her. But I'm ready to move on to greener pastures. 100. Master Mind's steel hand clinches into a fist at his side. Wayne's oblivious to this. MASTER MIND I guess I wasn't the villain I thought I was, and you...you weren't the hero I thought you were. He turns to make his exit when he suddenly sees ROXANNE STANDING IN THE DOOR FRAME. Wayne is almost at a loss for words. WAYNE SCOTT Roxanne! How long have you been... ROXANNE Long enough. Roxanne looks at Master Mind. ROXANNE (CONT'D) Don't you have something else you can go do? Master Mind leaves Roxanne and Wayne facing each other in silence. EXT. ANOTHER BAR - DAY Titan emerges with Brad and Frank. He's holding a BEER CAN and a bag of PORK RINDS. TITAN Alright, I want this whole thing to look ESPN professional, understand? A distant MECHANIZED RUMBLE can be heard. The noise rises, signaling the approach of something powerful. Titan and his crew walk out to the center of the plaza as the sound becomes almost deafening. A TANK TRACK as it moves over the street. We PULL BACK to see a whole line of TANKS rolling along the street. PLAZA From the five streets branching off the plaza, a dozen tanks roll toward Titan. 101. Titan turns to Brad and Frank. TITAN (CONT'D) You guys are about to get some good footage. I might need a little room, though. Brad and Frank look at each other and run to take cover behind a nearby building. Meanwhile, Titan nonchalantly sips from his beer as the tanks begin to surround them. FEEDBACK belts out of one of the tank's loudspeaker's, causing Titan to do a mock wince. TANK LOUDSPEAKER Titan, we have orders from the city of Metro to take you into custody. If you do not give your self up willingly, we will be forced to open fire. There's a long pause as no one says anything. TANK LOUDSPEAKER What is your answer? Titan takes a sip of his beverage and UNLEASHES A GIGANTIC BURP - The shockwave of which sends several of the tanks flying into a nearby building. Two of the remaining tanks close in on the villain. Both have him dead to rights at point-blank range with their massive guns. Titan sets down his beer, then calmly plugs a fist into each barrel. They FIRE. The FORCE OF THE BLAST SENDS THEM BOTH FLYING IN OPPOSITE DIRECTIONS where they CRASH into nearby buildings. Titan bends down and pick his beet back up. TITAN (to beer) Miss me? Titan is suddenly bombarded by a massive barrage of machine- gun fire. The force sends him flying into the windshield of a nearby car. 102. He looks up to see an APACHE ASSAULT COPTER. It's nose- mounted GATLING-GUN is turning toward him. Titan gets up to his feet and looks down at his beer can. The bottom of it was blown apart in the blast. TITAN (CONT'D) Didn't mean to get you involved in all of this. He stared daggers up at the helicopter pilot just as the gun gets a bead on him. TITAN (CONT'D) Hey, man! You killed my suds! Titan throws the can up and slaps it with the palm of his hand. It flies with so much force it knocks the helicopter blade clean off. The rest of the Apache crashes to the street like a car dropped off a building. TITAN (CONT'D) That's one was for you, beer. Titan salutes the wreckage and walks away to find Brad and Frank still hiding behind the building. TITAN Guys, please tell me you got that last bit. BRAD HELMS Huh? TITAN You're kidding me. I give you my sexiest moves and you mean to tell me it was for nothing? BRAD HELMS We were afraid something might hit us. TITAN Looks like I've given the story of the century to the wrong man. He thinks about this for a moment, then it hits him. 103. TITAN Wait. What about that other reporter. Blond. Not so lumpy on the topper half, but killer legs. BRAD HELMS Roxanne. You want Roxanne. She's a much better reporter than I am. You want her. TITAN Where can I find her. FRANK We're actually not supposed to give out that sort of information. BRAD HELMS 1314 Mockingbird Lane. I believe she lives in a penthouse. TITAN You've been very helpful. He tosses Brad over his shoulder like a discarded ice cream cone. In the faint distance we see him splash down in the middle of the Metro City river. INT. ABANDONED METRO CITY LIBRARY - DAY Master Mind, pacing anxiously as Plato and Da Vinci pack boxes. Obviously Master Mind is going on the lamb. MASTER MIND Hurry, we must be on our way as soon as possible. DA VINCI Master, why must we flee? MASTER MIND I told you, Titan is too powerful. If he's set on destroying us, there's precious little we could do about it. DA VINCI Where are we going? 104. MASTER MIND To another city, someplace with a shitload of superheroes to fight. We'll start over, we'll go back to doing what we do best. PLATO With our tails between our legs? The old Master Mind would never have let this comment slip by, but as we have seen, he's not the same man. MASTER MIND Plato, do you have a better plan?! Master Mind's cell phone rings. He turns in shame from his men and answers it. MASTER MIND (CONT'D) Hello...Roxanne? INT. ROXANNE'S APARTMENT Roxanne paces back and forth on the phone. ROXANNE What are you going to do about Tighten? INTERCUT between Master Mind and Roxanne on phone. MASTER MIND Right now I'm packing, later I'll have a snack on the train. ROXANNE You're running away? MASTER MIND In a word - yes. ROXANNE You created this monster... MASTER MIND I didn't create this - the god's of irony did and I am eating the crow I so richly deserve. ROXANNE There's no time for self pity. 105. MASTER MIND I'll make the time. Roxanne can't believe what she's hearing. MASTER MIND (CONT'D) You can leave with us. You'll be safe. ROXANNE I'm not going anywhere. MASTER MIND Will you listen to me, no one can stop him. ROXANNE You have to try. The city needs your help. MASTER MIND I'm afraid you have an inflated opinion of me. ROXANNE What the hell's happened to you? The Master Mind I knew would never have run from a fight even though he knew deep in his heart that he didn't have a chance in hell of winning it. It was your best quality. You need to be that man right now...I... MASTER MIND What? ROXANNE (heart felt) I believe in you. Master Mind is taken aback, in a good way. But he catches himself before the words swell his heart. MASTER MIND Sweet words, but that man is dead. Please, Roxanne, just come with me. ROXANNE No...I guess you are a coward after all. Suddenly, there's a loud crash. 106. Roxanne looks up to see a huge hunk of her ceiling has been completely ripped off. Titan is flying above, holding the debris as casually as if it were a paper plate at a barbecue. He looks down at her and smiles. TITAN Man, have I got a story for you. Master Mind can hears Titan's familiar laugh from his side of the line. MASTER MIND Roxanne? Roxanne? EXT. KINGPIN BOWLING - DAY Titan is standing in front of the bowling alley, trying to decide on an appropriate pose for the occasion. TITAN What pose would be best? The corny folded arms thing? He demonstrates, arching his chin proudly in the air. TITAN Or maybe on the hips, like this. It's the classic Superman pose, only not as masculine. TITAN No, makes me look like a flamer pirate. As Titan starts to fix his hair in the window, Frank pretends to fix the lens on his camera as he speaks to Roxanne. FRANK (whispering) Shouldn't we be making a run for it right about now? ROXANNE (whispering) The guy can outrun bullets. I don't think either one of us is in that kind of shape. TITAN She's right, Frank. 107. Frank looks up, stunned that Titan could have possibly heard him. TITAN Also got super hearing. I promise not to keep the both of you long, but you'll thank me when this is all over. Frank and Roxanne exchange helpless expressions. INT. ABANDONED METRO CITY LIBRARY - DAY Master Mind reverently stares up at the painted portrait of his father. MASTER MIND Dad, it's me... (he looks around to make sure no one can hear) ...Bubsy. I know we haven't talked in a while, and I'm sorry. It's been a little crazy trying to live up to a legacy. The painting's menacing stare seems to reach into his very soul. MASTER MIND Anyway...You raised me to be the worst that I could possibly be. And I've tried to live up to that as best as I could - even dropping out of dentistry school like you wanted me to. But I'm about to do something now that would really piss you off. I'm going to go against everything you ever taught me. I hope...I hope that maybe you'll look down at what I'm about to do as not so much a good deed, but more like the outright defiance of a hateful and ungrateful, son. If you could do that, then maybe - in your own little way - you could - for probably the first time - find a reason to be proud of me. He looks back up at the picture. Is it our imagination, or does the painting's stare suddenly seem even angrier? 108. MASTER MIND Well...either way, you're probably going to see me real soon. (calling over his shoulder) Men? Plato and Da Vinci suddenly stop what they're doing and look up at him. PLATO AND DA VINCI Yes Sir? MASTER MIND Stop packing. Our work is not finished here. PLATO AND DA VINCI YES SIR! TELEVISION A news report shows an aerial shot of Titan setting the giant ball down in the middle of a vacant city street. REPORTER We interrupt your regular afternoon programming to show you live footage of a potential dangerous situation in downtown Metro. The former hero knows as Titan is placing what appears to be a giant ball... INT. ABANDONED METRO CITY LIBRARY - CONTINUOUS Da Vinci stops in front of a television set, seeing the news report in progress. REPORTER Hold on...It appears our own Roxanne Ritchi is somehow at the scene. We now go to her with a live report. DA VINCI Sir, I think you should see this! CUT TO: 109. EXT. CITY STREET - DAY Roxanne is standing in front of a camera with a mike in her hand. ROXANNE I'm here with the cause of the destruction in Metro City. He has kidnapped me and a cameraman to chronicle what he refers to as the creation of a monument to his invincibility and overall "Asskickiness." He will use this giant concrete bowling ball to play the largest game of bowling ever using the buildings of downtown Metro City as his pins. Titan suddenly steps into the shot. TITAN And I'm going for the biggest strike ever. He leans into the camera. TITAN And you, Metro City, have a ringside seat as I cement my name in the anal of history. ROXANNE Annals. TITAN What? ROXANNE Nevermind. EXT. CITY STREET - MOMENTS LATER Titan holds up the massive bowling ball, lining up his shot. TITAN (in quiet professional bowler announcer voice) Like Tiger before him, a young savior has come to raise a sport from the ashes. Rookie Hal Stewart, a young man with a dream, realizing that dream here today, folks. (MORE) 110. TITAN(cont'd) One might click there heels and say "There's no place like home" upon finding themselves in such a fantasy. Well, Hal looks very much at home right were he is - with a ball in hand and glory in his sights. INT. METRO CITY LIBRARY - CONTINUOUS In the bowels of Master Mind's hideout, the HYDROGEN REACTOR glows and HUMS MENACINGLY. BACK TO SCENE Roxanne just stand helpless as Frank films away. ROXANNE Hal, I know everyone treated you like shit, but you don't have to do this. TITAN You're right. I don't HAVE to do anything. Isn't that cool? Titan lines up his shot. TITAN Here's one for the record books! Titan flies a few feet and rolls the ball down the main street. ROXANNE Her face is utter horror as she watches the inevitable destruction of Metro City. As the ball rolls - it demolishes everything in it's wake; cars, street lamps - windows shatter as the giant concrete sphere brushes along side buildings. TITAN He smiles in anticipation and uses "body English" to direct the ball. GIANT BOWLING BALL POV It's nearly halfway to its target. ROXANNE 111. She closes her eyes. Titan's smile fades. He looks around as if he hears something we don't. About two hundred feet in front of the first building a GIANT SPIDER WEB flies across the path of the ball, creating a defensive barrier. An enormous letter "M" is etched in the web's center. TITAN (CONT'D) What the...? The ball breaks through the web, but it's speed is greatly reduced. FRANK Look, what's that flying in the air? We suddenly see MASTER MIND FLYING OVER THE ROLLING BALL IN A JET PACK. He quickly pulls out his goo gun and starts laying down a path of sticky plasm to stop the destructive sphere's path. MASTER MIND C'mon, slow down Master Mind looks down to see the meter of the gun close to empty. MASTER MIND C'mon. The ball slows drastically then starts rolling to the side. It heads off an embankment and rolls harmlessly into a CANAL. MASTER MIND Gutterball! TITAN He's furious to say the least. TITAN YOU! Master Mind gives him a mocking grin. MASTER MIND Bowling? What other trailer park sports can you play? 112. TITAN You are becoming a real pain in my ass. I should have done this a long time ago. Titan lunges at his tormentor. Master Mind hits the BOOSTER on his jet pack and heads back toward the other side of the city with Titan in hot pursuit. MASTER MIND (CONT'D) (into walkie talkie) Plato, Da Vinci. Secure Roxanne, he's falling for it. ELSEWHERE A flustered Titan lands. He begins searching the city streets, but Master Mind is nowhere in sight. He turns upon hearing an EEKING sound to his left. Sitting on the ground is a CHIMPANZEE wearing a strange collar. It smiles at him. TITAN What the hell? From behind, Titan is immediately set upon by five more RADIO CONTROLLED APES. TITAN (CONT'D) GODAMNIT! The critters bite hop and hit Titan. As soon as he throws one off two more jump him. Titan breaks free and with his mighty breath blows them across the street into a fruit stand. With Titan out of their sight they begin to attack the fruit. MASTER MIND He's a block away frantically hitting his remote. MASTER MIND Shit! Stupid monkeys and their fruit. Titan flies away from the mad monkeys and lands to find Master Mind sitting on the ground wrapped in a long cape with only his head sticking out. 113. TITAN (CONT'D) No more games. Titan FIRES HIS LASER VISION AT MASTER MIND's CHEST. Master Mind pulls the cloak away to reveal a FIRE HYDRANT. Titan's EYE LASERS burn through the hydrant releasing a high pressure stream of water. Master Mind uses the last remote which dumps two tons of CEMENT mix into the truck. The crowd, police and news crews move in closer when Titan doesn't emerge. Master Mind drops his last remote and walks toward the truck cautiously. MASTER MIND Could it really be that easy-- - BOOM - The back of the truck explodes, throwing dust and concrete everywhere. When the dust clears we see and enraged Titan. MASTER MIND (CONT'D) Didn't think so. As the villain walks toward him, he pulls back his fist to give Master Mind the killing blow. TITAN If you don't mind, I'm going to punch trough your face now. Preparing himself for the end, Master Mind shuts his eyes as a SUDDEN GUST OF WIND BEGINS TO PICK UP. AS Titan goes to strike, a BLURRY FIGURE RUNS IN AND SNATCHES MASTER MIND OUT OF THE AWAY. Stunned, Master Mind begins to feel around his body as if to make sure everything's still in place. MASTER MIND I'm alive. He turns to see UBERMAN standing next to him. MASTER MIND Uberman? 114. The terrified bystanders start to notice the figure standing next to Master Mind. BYSTANDER 1 It's Uberman! BYSTANDER 2 Uberman's alive! BYSTANDER 3 We're saved! As the CROWD CHEERS, A confused Master Mind turns to Metro City's newly resurrected champion. MASTER MIND I thought. UBERMAN So did I. He puts a hand on Master Mind's shoulder. UBERMAN Thank you, old enemy. MASTER MIND For what? UBERMAN Showing me the error of my ways, Showing me I'm meant to be this city's savior, showing me that, while we can try, there is no running away from our true destiny. With that, UBERMAN IS STRICKEN BY A LASER BLAST, INSTANTLY TURNING HIM INTO A CHARRED HUMAN SKELETON. Master Mind turns to see Titan smiling with his STILL SMOKING EYES. TITAN Oh...Did I interrupt something? Master Mind turns to run, but, suddenly Titan is before him. TITAN Where you going, buddy? Titan grabs Master Mind by the collar and throws him across the street into a parked car. 115. TITAN (CONT'D) Welcome to Paintown. Population: you. Master Mind manages to stand on shaky legs. He seems in a daze, unable to move. Titan flies up in the air. TITAN (CONT'D) Time to finish this. With his fist front and center, Titan speeds toward Master Mind. He's like a human torpedo, coming in for the killing blow. Master Mind comes to his senses and puts up his hands. MASTER MIND WAIT!!! Titan screeches to a halt and stops just in front of him like an old Warner Bros cartoon. TITAN What? MASTER MIND Quick joke - What's the capital of Thailand? TITAN Huh - I don't know. MASTER MIND It's bang cock! In a sudden surge of strength, MASTER MIND PUNCHES TITAN IN THE GROIN. The once mighty man instantly drops to his knees, searching, with tears in his eyes, for the proper word to express the pain suddenly surging through his member. TITAN (CONT'D) Ow. Baffled, he looks up at Master Mind's hand and sees his gauntlet is now made ENTIRELY OUT OF COPPER. MASTER MIND So, I guess pennies are good for something. 116. He punches Titan in the face, knocking him out cold. Master Mind looks down on Titan with more than a little pride. Suddenly he hears something behind him. He spins to see the crowd making a strange noise - APPLAUSE. Roxanne comes up to him. The crowd starts to go wild and cheers for Master Mind. He's not sure what to make of it. ROXANNE Pretty strange, huh? MASTER MIND They're cheering for me. ROXANNE You saved them. You saved everybody. How's it feel? Master Mind looks at the smiles all around him. He begins to well up a little. MASTER MIND It's a...it's nice, you know? I usually don't get a lot of feedback. (whispering) But I also kind of caused all this. What happens when they find that out I was the cause of some of this? Roxanne looks at the cheering crowd, then back at Master Mind. ROXANNE What they don't know won't hurt them. MASTER MIND I guess that is all in the past. ROXANNE You're the hero. MASTER MIND I don't think I'd go that far...I mean I just...er... ROXANNE Master Mind? 117. MASTER MIND Yes? ROXANNE Stop talking. She kisses him. The crowd erupts in a cheer. TELEVISION The channel 7 he channel 7 logo zooms in followed by the title "Eye on Metro City." A picture of Master Mind smiling appears on the screen behind her. SAMANTHA SUMMERS Who's bad? Well, not Master Mind. It seems the former villain has done a career 180 after defeating Tighten and saving Metro City from certain enslavement. And here he is getting a full pardon by Metro City's Mayor, Steve Dent. Cut to ceremony on capital steps. The MAYOR is shaking Master Mind's metal gauntlet when it suddenly STARTS TO CRUSH HIS HAND. MAYOR Ahhh! Secret service men quickly start to draw their weapons and take aim at Master Mind. Realizing what's happening, he quickly lets the mayor's hand go and puts his arms in the air. MASTER MIND Sorry - Metal hand. Force of habit. He elbows the mayor. MASTER MIND (CONT'D) We're okay, right? Wincing, the mayor signals the men to put their guns down. WE CUT to video of Titan behind bars in a regular prison. 118. BRAD HELMS And what about Tighten? Is there a prison in existence that can hold this super powered menace? Well, the answer we found is no. A man in a white lab coat stands in front of Titan's cell just out of reach. PRISON SCIENTIST Of course normally he could break out of there anytime, but as you can see we've taken some special precautions. The news camera pans over see Titan in his cell wearing a copper JOCK STRAP with electrical cables hooked to it. Back to Samantha at the desk. BRAD HELMS What is a Hero? It seems never has that question needed to be asked more than it does tonight. We go to our very own Roxanne Ritchi, making her triumphant return to our news desk for the answer. Brad turns. The camera pans over to Roxanne who we now see has been sitting beside him. ROXANNE What is a hero? Well, there are many different kinds. There are those who hear a call, like the policeman or doctor, then there's the kind the public creates in their search for meaning and hope. Then, there are those who have the courage to change. DARK ALLEY - NIGHT A woman is being chased by two large thugs. They're gaining on her. She comes to a brick wall - a dead end. The thugs laugh. THUG #1 Hey, gimme that purse? 119. MASTER MIND (O.S) I don't think it would go with your outfit. The thugs turn around to see Master Mind, standing with his arms folded across his chest. THUG #2 It's Master Mind! Thug #1 draws a knife. THUG #1 So? It's not like he has any superpowers. Thug #1 puts his fingers to his mouth and whistles. Suddenly two more Thugs appear behind Master Mind. MASTER MIND I'm gonna give you a chance to surrender. THUG #1 Four against one. For a Master Mind, you're really bad at math. Master Mind throws a hand signal up in the air. Suddenly a giant robotic foot crashes down on the two men behind him. Thug #1 and Thug #2 drop their knives and raise their hands in the air. Master Mind looks up and waves. MASTER MIND Way to take out those two goons, guys! We see Da Vinci and Plato at the wheel of a gigantic robot. DA VINCI What two goons? The giant robot lifts its foot to check the bottom of it's sole. It KNOCKS OVER WATER TOWER in the process. The woman looks at Master Mind, horrified. 120. MASTER MIND (apologetically) Sorry, we're new at this. THE END

Replaced with menu which allows specifying type for gamepads with unknown VID and PID Attempts to auto-detect gamepad type based on USB VID and PID If gamepad VID and PID is not known, use type specified by user for that VID and PID If gamepad VID and PID is not known AND the user has not specified a type for that VID and PID, an educated guess is made about how to map the gamepad Driver Station will now attempt to automatically recover from a gamepad disconnecting, and re-assign it to the position it was assigned to when it dropped If only one gamepad is assigned and it drops: it can be recovered If two gamepads are assigned, and have different VID/PID signatures, and only one drops: it will be recovered If two gamepads are assigned, and have different VID/PID signatures, and BOTH drop: both will be recovered If two gamepads are assigned, and have the same VID/PID signatures, and only one drops: it will be recovered If two gamepads are assigned, and have the same VID/PID signatures, and BOTH drop: neither will be recovered, because of the ambiguity of the gamepads when they re-appear on the USB bus. There is currently one known edge case: if there are two gamepads with the same VID/PID signature plugged in, but only one is assigned, and they BOTH drop, it's a 50-50 chance of which one will be chosen for automatic recovery to the assigned position: it is determined by whichever one is re-enumerated first by the USB bus controller. Adds landscape user interface to Driver Station New feature: practice timer with audio cues New feature (Control Hub only): wireless network connection strength indicator (0-5 bars) New feature (Control Hub only): tapping on the ping/channel display will switch to an alternate display showing radio RX dBm and link speed (tap again to switch back) The layout will NOT autorotate. You can switch the layout from the Driver Station's settings menu. Breaking changes Removes support for Android versions 4.4 through 5.1 (KitKat and Lollipop). The minSdkVersion is now 23. Removes the deprecated LinearOpMode methods waitOneFullHardwareCycle() and waitForNextHardwareCycle() Enhancements Handles RS485 address of Control Hub automatically The Control Hub is automatically given a reserved address Existing configuration files will continue to work All addresses in the range of 1-10 are still available for Expansion Hubs The Control Hub light will now normally be solid green, without blinking to indicate the address The Control Hub will not be shown on the Expansion Hub Address Change settings page Improves REV Hub firmware updater The user can now choose between all available firmware update files Version 1.8.2 of the REV Hub firmware is bundled into the Robot Controller app. Text was added to clarify that Expansion Hubs can only be updated via USB. Firmware update speed was reduced to improve reliability Allows REV Hub firmware to be updated directly from the Manage webpage Improves log viewer on Robot Controller Horizontal scrolling support (no longer word wrapped) Supports pinch-to-zoom Uses a monospaced font Error messages are highlighted New color scheme Attempts to force-stop a runaway/stuck OpMode without restarting the entire app Not all types of runaway conditions are stoppable, but if the user code attempts to talk to hardware during the runaway, the system should be able to capture it. Makes various tweaks to the Self Inspect screen Renames "OS version" entry to "Android version" Renames "WiFi Direct Name" to "WiFi Name" Adds Control Hub OS version, when viewing the report of a Control Hub Hides the airplane mode entry, when viewing the report of a Control Hub Removes check for ZTE Speed Channel Changer Shows firmware version for all Expansion and Control Hubs Reworks network settings portion of Manage page All network settings are now applied with a single click The WiFi Direct channel of phone-based Robot Controllers can now be changed from the Manage page WiFi channels are filtered by band (2.4 vs 5 GHz) and whether they overlap with other channels The current WiFi channel is pre-selected on phone-based Robot Controllers, and Control Hubs running OS 1.1.2 or later. On Control Hubs running OS 1.1.2 or later, you can choose to have the system automatically select a channel on the 5 GHz band Improves OnBotJava New light and dark themes replace the old themes (chaos, github, chrome,...) the new default theme is light and will be used when you first update to this version OnBotJava now has a tabbed editor Read-only offline mode Improves function of "exit" menu item on Robot Controller and Driver Station Now guaranteed to be fully stopped and unloaded from memory Shows a warning message if a LinearOpMode exists prematurely due to failure to monitor for the start condition Improves error message shown when the Driver Station and Robot Controller are incompatible with each other Driver Station OpMode Control Panel now disabled while a Restart Robot is in progress Disables advanced settings related to WiFi direct when the Robot Controller is a Control Hub. Tint phone battery icons on Driver Station when low/critical. Uses names "Control Hub Portal" and "Control Hub" (when appropriate) in new configuration files Improve I2C read performance Very large improvement on Control Hub; up to ~2x faster with small (e.g. 6 byte) reads Not as apparent on Expansion Hubs connected to a phone Update/refresh build infrastructure Update to 'androidx' support library from 'com.android.support:appcompat', which is end-of-life Update targetSdkVersion and compileSdkVersion to 28 Update Android Studio's Android plugin to latest Fix reported build timestamp in 'About' screen Add sample illustrating manual webcam use: ConceptWebcam Bug fixes Fixes SkyStone issue #248 Fixes SkyStone issue #232 and modifies bulk caching semantics to allow for cache-preserving MANUAL/AUTO transitions. Improves performance when REV 2M distance sensor is unplugged Improves readability of Toast messages on certain devices Allows a Driver Station to connect to a Robot Controller after another has disconnected Improves generation of fake serial numbers for UVC cameras which do not provide a real serial number Previously some devices would assign such cameras a serial of 0:0 and fail to open and start streaming Fixes ftc_app issue #638. Fixes a slew of bugs with the Vuforia camera monitor including: Fixes bug where preview could be displayed with a wonky aspect ratio Fixes bug where preview could be cut off in landscape Fixes bug where preview got totally messed up when rotating phone Fixes bug where crosshair could drift off target when using webcams Fixes issue in UVC driver on some devices (ftc_app 681) if streaming was started/stopped multiple times in a row Issue manifested as kernel panic on devices which do not have this kernel patch. On affected devices which do have the patch, the issue was manifest as simply a failure to start streaming. The Tech Team believes that the root cause of the issue is a bug in the Linux kernel XHCI driver. A workaround was implemented in the SDK UVC driver. Fixes bug in UVC driver where often half the frames from the camera would be dropped (e.g. only 15FPS delivered during a streaming session configured for 30FPS). Fixes issue where TensorFlow Object Detection would show results whose confidence was lower than the minimum confidence parameter. Fixes a potential exploitation issue of CVE-2019-11358 in OnBotJava Fixes changing the address of an Expansion Hub with additional Expansion Hubs connected to it Preserves the Control Hub's network connection when "Restart Robot" is selected Fixes issue where device scans would fail while the Robot was restarting Fix RenderScript usage Use androidx.renderscript variant: increased compatibility Use RenderScript in Java mode, not native: simplifies build Fixes webcam-frame-to-bitmap conversion problem: alpha channel wasn't being initialized, only R, G, & B Fixes possible arithmetic overflow in Deadline Fixes deadlock in Vuforia webcam support which could cause 5-second delays when stopping OpMode Version 5.4 (20200108-101156) Fixes SkyStone issue #88 Adds an inspection item that notes when a robot controller (Control Hub) is using the factory default password. Fixes SkyStone issue #61 Fixes SkyStone issue #142 Fixes ftc_app issue #417 by adding more current and voltage monitoring capabilities for REV Hubs. Fixes a crash sometimes caused by OnBotJava activity Improves OnBotJava autosave functionality ftc_app #738 Fixes system responsiveness issue when an Expansion Hub is disconnected Fixes issue where IMU initialization could prevent Op Modes from stopping Fixes issue where AndroidTextToSpeech.speak() would fail if it was called too early Adds telemetry.speak() methods and blocks, which cause the Driver Station (if also updated) to speak text Adds and improves Expansion Hub-related warnings Improves Expansion Hub low battery warning Displays the warning immediately after the hub reports it Specifies whether the condition is current or occurred temporarily during an OpMode run Displays which hubs reported low battery Displays warning when hub loses and regains power during an OpMode run Fixes the hub's LED pattern after this condition Displays warning when Expansion Hub is not responding to commands Specifies whether the condition is current or occurred temporarily during an OpMode run Clarifies warning when Expansion Hub is not present at startup Specifies that this condition requires a Robot Restart before the hub can be used. The hub light will now accurately reflect this state Improves logging and reduces log spam during these conditions Syncs the Control Hub time and timezone to a connected web browser programming the robot, if a Driver Station is not available. Adds bulk read functionality for REV Hubs A bulk caching mode must be set at the Hub level with LynxModule#setBulkCachingMode(). This applies to all relevant SDK hardware classes that reference that Hub. The following following Hub bulk caching modes are available: BulkCachingMode.OFF (default): All hardware calls operate as usual. Bulk data can read through LynxModule#getBulkData() and processed manually. BulkCachingMode.AUTO: Applicable hardware calls are served from a bulk read cache that is cleared/refreshed automatically to ensure identical commands don't hit the same cache. The cache can also be cleared manually with LynxModule#clearBulkCache(), although this is not recommended. (advanced users) BulkCachingMode.MANUAL: Same as BulkCachingMode.AUTO except the cache is never cleared automatically. To avoid getting stale data, the cache must be manually cleared at the beginning of each loop body or as the user deems appropriate. Removes PIDF Annotation values added in Rev 5.3 (to AndyMark, goBILDA and TETRIX motor configurations). The new motor types will still be available but their Default control behavior will revert back to Rev 5.2 Adds new ConceptMotorBulkRead sample Opmode to demonstrate and compare Motor Bulk-Read modes for reducing I/O latencies. Version 5.3 (20191004-112306) Fixes external USB/UVC webcam support Makes various bugfixes and improvements to Blocks page, including but not limited to: Many visual tweaks Browser zoom and window resize behave better Resizing the Java preview pane works better and more consistently across browsers The Java preview pane consistently gets scrollbars when needed The Java preview pane is hidden by default on phones Internet Explorer 11 should work Large dropdown lists display properly on lower res screens Disabled buttons are now visually identifiable as disabled A warning is shown if a user selects a TFOD sample, but their device is not compatible Warning messages in a Blocks op mode are now visible by default. Adds goBILDA 5201 and 5202 motors to Robot Configurator Adds PIDF Annotation values to AndyMark, goBILDA and TETRIX motor configurations. This has the effect of causing the RUN_USING_ENCODERS and RUN_TO_POSITION modes to use PIDF vs PID closed loop control on these motors. This should provide more responsive, yet stable, speed control. PIDF adds Feedforward control to the basic PID control loop. Feedforward is useful when controlling a motor's speed because it "anticipates" how much the control voltage must change to achieve a new speed set-point, rather than requiring the integrated error to change sufficiently. The PIDF values were chosen to provide responsive, yet stable, speed control on a lightly loaded motor. The more heavily a motor is loaded (drag or friction), the more noticable the PIDF improvement will be. Fixes startup crash on Android 10 Fixes ftc_app issue #712 (thanks to FROGbots-4634) Fixes ftc_app issue #542 Allows "A" and lowercase letters when naming device through RC and DS apps. Version 5.2 (20190905-083277) Fixes extra-wide margins on settings activities, and placement of the new configuration button Adds Skystone Vuforia image target data. Includes sample Skystone Vuforia Navigation op modes (Java). Includes sample Skystone Vuforia Navigation op modes (Blocks). Adds TensorFlow inference model (.tflite) for Skystone game elements. Includes sample Skystone TensorFlow op modes (Java). Includes sample Skystone TensorFlow op modes (Blocks). Removes older (season-specific) sample op modes. Includes 64-bit support (to comply with Google Play requirements). Protects against Stuck OpModes when a Restart Robot is requested. (Thanks to FROGbots-4634) (ftc_app issue #709) Blocks related changes: Fixes bug with blocks generated code when hardware device name is a java or javascript reserved word. Shows generated java code for blocks, even when hardware items are missing from the active configuration. Displays warning icon when outdated Vuforia and TensorFlow blocks are used (SkyStone issue #27) Version 5.1 (20190820-222104) Defines default PIDF parameters for the following motors: REV Core Hex Motor REV 20:1 HD Hex Motor REV 40:1 HD Hex Motor Adds back button when running on a device without a system back button (such as a Control Hub) Allows a REV Control Hub to update the firmware on a REV Expansion Hub via USB Fixes SkyStone issue #9 Fixes ftc_app issue #715 Prevents extra DS User clicks by filtering based on current state. Prevents incorrect DS UI state changes when receiving new OpMode list from RC Adds support for REV Color Sensor V3 Adds a manual-refresh DS Camera Stream for remotely viewing RC camera frames. To show the stream on the DS, initialize but do not run a stream-enabled opmode, select the Camera Stream option in the DS menu, and tap the image to refresh. This feature is automatically enabled when using Vuforia or TFOD—no additional RC configuration is required for typical use cases. To hide the stream, select the same menu item again. Note that gamepads are disabled and the selected opmode cannot be started while the stream is open as a safety precaution. To use custom streams, consult the API docs for CameraStreamServer#setSource and CameraStreamSource. Adds many Star Wars sounds to RobotController resources. Added SKYSTONE Sounds Chooser Sample Program. Switches out startup, connect chimes, and error/warning sounds for Star Wars sounds Updates OnBot Java to use a WebSocket for communication with the robot The OnBot Java page no longer has to do a full refresh when a user switches from editing one file to another Known issues: Camera Stream The Vuforia camera stream inherits the issues present in the phone preview (namely ftc_app issue #574). This problem does not affect the TFOD camera stream even though it receives frames from Vuforia. The orientation of the stream frames may not always match the phone preview. For now, these frames may be rotated manually via a custom CameraStreamSource if desired. OnBotJava Browser back button may not always work correctly It's possible for a build to be queued, but not started. The OnBot Java build console will display a warning if this occurs. A user might not realize they are editing a different file if the user inadvertently switches from one file to another since this switch is now seamless. The name of the currently open file is displayed in the browser tab. Version 5.0 (built on 19.06.14) Support for the REV Robotics Control Hub. Adds a Java preview pane to the Blocks editor. Adds a new offline export feature to the Blocks editor. Display wifi channel in Network circle on Driver Station. Adds calibration for Logitech C270 Updates build tooling and target SDK. Compliance with Google's permissions infrastructure (Required after build tooling update). Keep Alives to mitigate the Motorola wifi scanning problem. Telemetry substitute no longer necessary. Improves Vuforia error reporting. Fixes ftctechnh/ftc_app issues 621, 713. Miscellaneous bug fixes and improvements. Version 4.3 (built on 18.10.31) Includes missing TensorFlow-related libraries and files. Version 4.2 (built on 18.10.30) Includes fix to avoid deadlock situation with WatchdogMonitor which could result in USB communication errors. Comm error appeared to require that user disconnect USB cable and restart the Robot Controller app to recover. robotControllerLog.txt would have error messages that included the words "E RobotCore: lynx xmit lock: #### abandoning lock:" Includes fix to correctly list the parent module address for a REV Robotics Expansion Hub in a configuration (.xml) file. Bug in versions 4.0 and 4.1 would incorrect list the address module for a parent REV Robotics device as "1". If the parent module had a higher address value than the daisy-chained module, then this bug would prevent the Robot Controller from communicating with the downstream Expansion Hub. Added requirement for ACCESS_COARSE_LOCATION to allow a Driver Station running Android Oreo to scan for Wi-Fi Direct devices. Added google() repo to build.gradle because aapt2 must be downloaded from the google() repository beginning with version 3.2 of the Android Gradle Plugin. Important Note: Android Studio users will need to be connected to the Internet the first time build the ftc_app project. Internet connectivity is required for the first build so the appropriate files can be downloaded from the Google repository. Users should not need to be connected to the Internet for subsequent builds. This should also fix buid issue where Android Studio would complain that it "Could not find com.android.tools.lint:lint-gradle:26.1.4" (or similar). Added support for REV Spark Mini motor controller as part of the configuration menu for a servo/PWM port on the REV Expansion Hub. Provide examples for playing audio files in an Op Mode. Block Development Tool Changes Includes a fix for a problem with the Velocity blocks that were reported in the FTC Technology forum (Blocks Programming subforum). Change the "Save completed successfully." message to a white color so it will contrast with a green background. Fixed the "Download image" feature so it will work if there are text blocks in the op mode. Introduce support for Google's TensorFlow Lite technology for object detetion for 2018-2019 game. TensorFlow lite can recognize Gold Mineral and Silver Mineral from 2018-2019 game. Example Java and Block op modes are included to show how to determine the relative position of the gold block (left, center, right). Version 4.1 (released on 18.09.24) Changes include: Fix to prevent crash when deprecated configuration annotations are used. Change to allow FTC Robot Controller APK to be auto-updated using FIRST Global Control Hub update scripts. Removed samples for non supported / non legal hardware. Improvements to Telemetry.addData block with "text" socket. Updated Blocks sample op mode list to include Rover Ruckus Vuforia example. Update SDK library version number. Version 4.0 (released on 18.09.12) Changes include: Initial support for UVC compatible cameras If UVC camera has a unique serial number, RC will detect and enumerate by serial number. If UVC camera lacks a unique serial number, RC will only support one camera of that type connected. Calibration settings for a few cameras are included (see TeamCode/src/main/res/xml/teamwebcamcalibrations.xml for details). User can upload calibration files from Program and Manage web interface. UVC cameras seem to draw a fair amount of electrical current from the USB bus. This does not appear to present any problems for the REV Robotics Control Hub. This does seem to create stability problems when using some cameras with an Android phone-based Robot Controller. FTC Tech Team is investigating options to mitigate this issue with the phone-based Robot Controllers. Updated sample Vuforia Navigation and VuMark Op Modes to demonstrate how to use an internal phone-based camera and an external UVC webcam. Support for improved motor control. REV Robotics Expansion Hub firmware 1.8 and greater will support a feed forward mechanism for closed loop motor control. FTC SDK has been modified to support PIDF coefficients (proportional, integral, derivative, and feed forward). FTC Blocks development tool modified to include PIDF programming blocks. Deprecated older PID-related methods and variables. REV's 1.8.x PIDF-related changes provide a more linear and accurate way to control a motor. Wireless Added 5GHz support for wireless channel changing for those devices that support it. Tested with Moto G5 and E4 phones. Also tested with other (currently non-approved) phones such as Samsung Galaxy S8. Improved Expansion Hub firmware update support in Robot Controller app Changes to make the system more robust during the firmware update process (when performed through Robot Controller app). User no longer has to disconnect a downstream daisy-chained Expansion Hub when updating an Expansion Hub's firmware. If user is updating an Expansion Hub's firmware through a USB connection, he/she does not have to disconnect RS485 connection to other Expansion Hubs. The user still must use a USB connection to update an Expansion Hub's firmware. The user cannot update the Expansion Hub firmware for a downstream device that is daisy chained through an RS485 connection. If an Expansion Hub accidentally gets "bricked" the Robot Controller app is now more likely to recognize the Hub when it scans the USB bus. Robot Controller app should be able to detect an Expansion Hub, even if it accidentally was bricked in a previous update attempt. Robot Controller app should be able to install the firmware onto the Hub, even if if accidentally was bricked in a previous update attempt. Resiliency FTC software can detect and enable an FTDI reset feature that is available with REV Robotics v1.8 Expansion Hub firmware and greater. When enabled, the Expansion Hub can detect if it hasn't communicated with the Robot Controller over the FTDI (USB) connection. If the Hub hasn't heard from the Robot Controller in a while, it will reset the FTDI connection. This action helps system recover from some ESD-induced disruptions. Various fixes to improve reliability of FTC software. Blocks Fixed errors with string and list indices in blocks export to java. Support for USB connected UVC webcams. Refactored optimized Blocks Vuforia code to support Rover Ruckus image targets. Added programming blocks to support PIDF (proportional, integral, derivative and feed forward) motor control. Added formatting options (under Telemetry and Miscellaneous categories) so user can set how many decimal places to display a numerical value. Support to play audio files (which are uploaded through Blocks web interface) on Driver Station in addition to the Robot Controller. Fixed bug with Download Image of Blocks feature. Support for REV Robotics Blinkin LED Controller. Support for REV Robotics 2m Distance Sensor. Added support for a REV Touch Sensor (no longer have to configure as a generic digital device). Added blocks for DcMotorEx methods. These are enhanced methods that you can use when supported by the motor controller hardware. The REV Robotics Expansion Hub supports these enhanced methods. Enhanced methods include methods to get/set motor velocity (in encoder pulses per second), get/set PIDF coefficients, etc.. Modest Improvements in Logging Decrease frequency of battery checker voltage statements. Removed non-FTC related log statements (wherever possible). Introduced a "Match Logging" feature. Under "Settings" a user can enable/disable this feature (it's disabled by default). If enabled, user provides a "Match Number" through the Driver Station user interface (top of the screen). The Match Number is used to create a log file specifically with log statements from that particular Op Mode run. Match log files are stored in /sdcard/FIRST/matlogs on the Robot Controller. Once an op mode run is complete, the Match Number is cleared. This is a convenient way to create a separate match log with statements only related to a specific op mode run. New Devices Support for REV Robotics Blinkin LED Controller. Support for REV Robotics 2m Distance Sensor. Added configuration option for REV 20:1 HD Hex Motor. Added support for a REV Touch Sensor (no longer have to configure as a generic digital device). Miscellaneous Fixed some errors in the definitions for acceleration and velocity in our javadoc documentation. Added ability to play audio files on Driver Station When user is configuring an Expansion Hub, the LED on the Expansion Hub will change blink pattern (purple-cyan) to indicate which Hub is currently being configured. Renamed I2cSensorType to I2cDeviceType. Added an external sample Op Mode that demonstrates localization using 2018-2019 (Rover Ruckus presented by QualComm) Vuforia targets. Added an external sample Op Mode that demonstrates how to use the REV Robotics 2m Laser Distance Sensor. Added an external sample Op Mode that demonstrates how to use the REV Robotics Blinkin LED Controller. Re-categorized external Java sample Op Modes to "TeleOp" instead of "Autonomous". Known issues: Initial support for UVC compatible cameras UVC cameras seem to draw significant amount of current from the USB bus. This does not appear to present any problems for the REV Robotics Control Hub. This does seem to create stability problems when using some cameras with an Android phone-based Robot Controller. FTC Tech Team is investigating options to mitigate this issue with the phone-based Robot Controllers. There might be a possible deadlock which causes the RC to become unresponsive when using a UVC webcam with a Nougat Android Robot Controller. Wireless When user selects a wireless channel, this channel does not necessarily persist if the phone is power cycled. Tech Team is hoping to eventually address this issue in a future release. Issue has been present since apps were introduced (i.e., it is not new with the v4.0 release). Wireless channel is not currently displayed for WiFi Direct connections. Miscellaneous The blink indication feature that shows which Expansion Hub is currently being configured does not work for a newly created configuration file. User has to first save a newly created configuration file and then close and re-edit the file in order for blink indicator to work. Version 3.6 (built on 17.12.18) Changes include: Blocks Changes Uses updated Google Blockly software to allow users to edit their op modes on Apple iOS devices (including iPad and iPhone). Improvement in Blocks tool to handle corrupt op mode files. Autonomous op modes should no longer get switched back to tele-op after re-opening them to be edited. The system can now detect type mismatches during runtime and alert the user with a message on the Driver Station. Updated javadoc documentation for setPower() method to reflect correct range of values (-1 to +1). Modified VuforiaLocalizerImpl to allow for user rendering of frames Added a user-overrideable onRenderFrame() method which gets called by the class's renderFrame() method. Version 3.5 (built on 17.10.30) Changes with version 3.5 include: Introduced a fix to prevent random op mode stops, which can occur after the Robot Controller app has been paused and then resumed (for example, when a user temporarily turns off the display of the Robot Controller phone, and then turns the screen back on). Introduced a fix to prevent random op mode stops, which were previously caused by random peer disconnect events on the Driver Station. Fixes issue where log files would be closed on pause of the RC or DS, but not re-opened upon resume. Fixes issue with battery handler (voltage) start/stop race. Fixes issue where Android Studio generated op modes would disappear from available list in certain situations. Fixes problem where OnBot Java would not build on REV Robotics Control Hub. Fixes problem where OnBot Java would not build if the date and time on the Robot Controller device was "rewound" (set to an earlier date/time). Improved error message on OnBot Java that occurs when renaming a file fails. Removed unneeded resources from android.jar binaries used by OnBot Java to reduce final size of Robot Controller app. Added MR_ANALOG_TOUCH_SENSOR block to Blocks Programming Tool. Version 3.4 (built on 17.09.06) Changes with version 3.4 include: Added telemetry.update() statement for BlankLinearOpMode template. Renamed sample Block op modes to be more consistent with Java samples. Added some additional sample Block op modes. Reworded OnBot Java readme slightly. Version 3.3 (built on 17.09.04) This version of the software includes improves for the FTC Blocks Programming Tool and the OnBot Java Programming Tool. Changes with verion 3.3 include: Android Studio ftc_app project has been updated to use Gradle Plugin 2.3.3. Android Studio ftc_app project is already using gradle 3.5 distribution. Robot Controller log has been renamed to /sdcard/RobotControllerLog.txt (note that this change was actually introduced w/ v3.2). Improvements in I2C reliability. Optimized I2C read for REV Expansion Hub, with v1.7 firmware or greater. Updated all external/samples (available through OnBot and in Android project folder). Vuforia Added support for VuMarks that will be used for the 2017-2018 season game. Blocks Update to latest Google Blockly release. Sample op modes can be selected as a template when creating new op mode. Fixed bug where the blocks would disappear temporarily when mouse button is held down. Added blocks for Range.clip and Range.scale. User can now disable/enable Block op modes. Fix to prevent occasional Blocks deadlock. OnBot Java Significant improvements with autocomplete function for OnBot Java editor. Sample op modes can be selected as a template when creating new op mode. Fixes and changes to complete hardware setup feature. Updated (and more useful) onBot welcome message. Known issues: Android Studio After updating to the new v3.3 Android Studio project folder, if you get error messages indicating "InvalidVirtualFileAccessException" then you might need to do a File->Invalidate Caches / Restart to clear the error. OnBot Java Sometimes when you push the build button to build all op modes, the RC returns an error message that the build failed. If you press the build button a second time, the build typically suceeds. Version 3.2 (built on 17.08.02) This version of the software introduces the "OnBot Java" Development Tool. Similar to the FTC Blocks Development Tool, the FTC OnBot Java Development Tool allows a user to create, edit and build op modes dynamically using only a Javascript-enabled web browser. The OnBot Java Development Tool is an integrated development environment (IDE) that is served up by the Robot Controller. Op modes are created and edited using a Javascript-enabled browser (Google Chromse is recommended). Op modes are saved on the Robot Controller Android device directly. The OnBot Java Development Tool provides a Java programming environment that does NOT need Android Studio. Changes with version 3.2 include: Enhanced web-based development tools Introduction of OnBot Java Development Tool. Web-based programming and management features are "always on" (user no longer needs to put Robot Controller into programming mode). Web-based management interface (where user can change Robot Controller name and also easily download Robot Controller log file). OnBot Java, Blocks and Management features available from web based interface. Blocks Programming Development Tool: Changed "LynxI2cColorRangeSensor" block to "REV Color/range sensor" block. Fixed tooltip for ColorSensor.isLightOn block. Added blocks for ColorSensor.getNormalizedColors and LynxI2cColorRangeSensor.getNormalizedColors. Added example op modes for digital touch sensor and REV Robotics Color Distance sensor. User selectable color themes. Includes many minor enhancements and fixes (too numerous to list). Known issues: Auto complete function is incomplete and does not support the following (for now): Access via this keyword Access via super keyword Members of the super cloass, not overridden by the class Any methods provided in the current class Inner classes Can't handle casted objects Any objects coming from an parenthetically enclosed expression Version 3.10 (built on 17.05.09) This version of the software provides support for the REV Robotics Expansion Hub. This version also includes improvements in the USB communication layer in an effort to enhance system resiliency. If you were using a 2.x version of the software previously, updating to version 3.1 requires that you also update your Driver Station software in addition to updating the Robot Controller software. Also note that in version 3.10 software, the setMaxSpeed and getMaxSpeed methods are no longer available (not deprecated, they have been removed from the SDK). Also note that the the new 3.x software incorporates motor profiles that a user can select as he/she configures the robot. Changes include: Blocks changes Added VuforiaTrackableDefaultListener.getPose and Vuforia.trackPose blocks. Added optimized blocks support for Vuforia extended tracking. Added atan2 block to the math category. Added useCompetitionFieldTargetLocations parameter to Vuforia.initialize block. If set to false, the target locations are placed at (0,0,0) with target orientation as specified in https://github.com/gearsincorg/FTCVuforiaDemo/blob/master/Robot_Navigation.java tutorial op mode. Incorporates additional improvements to USB comm layer to improve system resiliency (to recover from a greater number of communication disruptions). Additional Notes Regarding Version 3.00 (built on 17.04.13) In addition to the release changes listed below (see section labeled "Version 3.00 (built on 17.04.013)"), version 3.00 has the following important changes: Version 3.00 software uses a new version of the FTC Robocol (robot protocol). If you upgrade to v3.0 on the Robot Controller and/or Android Studio side, you must also upgrade the Driver Station software to match the new Robocol. Version 3.00 software removes the setMaxSpeed and getMaxSpeed methods from the DcMotor class. If you have an op mode that formerly used these methods, you will need to remove the references/calls to these methods. Instead, v3.0 provides the max speed information through the use of motor profiles that are selected by the user during robot configuration. Version 3.00 software currently does not have a mechanism to disable extra i2c sensors. We hope to re-introduce this function with a release in the near future. Version 3.00 (built on 17.04.13) *** Use this version of the software at YOUR OWN RISK!!! *** This software is being released as an "alpha" version. Use this version at your own risk! This pre-release software contains SIGNIFICANT changes, including changes to the Wi-Fi Direct pairing mechanism, rewrites of the I2C sensor classes, changes to the USB/FTDI layer, and the introduction of support for the REV Robotics Expansion Hub and the REV Robotics color-range-light sensor. These changes were implemented to improve the reliability and resiliency of the FTC control system. Please note, however, that version 3.00 is considered "alpha" code. This code is being released so that the FIRST community will have an opportunity to test the new REV Expansion Hub electronics module when it becomes available in May. The developers do not recommend using this code for critical applications (i.e., competition use). *** Use this version of the software at YOUR OWN RISK!!! *** Changes include: Major rework of sensor-related infrastructure.

Channel change is enabled in the FTC Robot Controller app for Moto G 2nd and 3rd Gen phones. Users can now use annotations to register/disable their Op Modes. Changes in the Android SDK, JDK and build tool requirements (minsdk=19, java 1.7, build tools 23.0.3). Standardized units in analog input. Cleaned up code for existing analog sensor classes. setChannelMode and getChannelMode were REMOVED from the DcMotorController class. This is important - we no longer set the motor modes through the motor controller. setMode and getMode were added to the DcMotor class. ContinuousRotationServo class has been added to the FTC SDK. Range.clip() method has been overloaded so it can support this operation for int, short and byte integers. Some changes have been made (new methods added) on how a user can access items from the hardware map. Users can now set the zero power behavior for a DC motor so that the motor will brake or float when power is zero. Prototype Blockly Programming Mode has been added to FTC Robot Controller. Users can place the Robot Controller into this mode, and then use a device (such as a laptop) that has a Javascript enabled browser to write Blockly-based Op Modes directly onto the Robot Controller. Users can now configure the robot remotely through the FTC Driver Station app. Android Studio project supports Android Studio 2.1.x and compile SDK Version 23 (Marshmallow). Vuforia Computer Vision SDK integrated into FTC SDK. Users can use sample vision targets to get localization information on a standard FTC field. Project structure has been reorganized so that there is now a TeamCode package that users can use to place their local/custom Op Modes into this package. Inspection function has been integrated into the FTC Robot Controller and Driver Station Apps (Thanks Team HazMat… 9277 & 10650!). Audio cues have been incorporated into FTC SDK. Swap mechanism added to FTC Robot Controller configuration activity. For example, if you have two motor controllers on a robot, and you misidentified them in your configuration file, you can use the Swap button to swap the devices within the configuration file (so you do not have to manually re-enter in the configuration info for the two devices). Fix mechanism added to all user to replace an electronic module easily. For example, suppose a servo controller dies on your robot. You replace the broken module with a new module, which has a different serial number from the original servo controller. You can use the Fix button to automatically reconfigure your configuration file to use the serial number of the new module. Improvements made to fix resiliency and responsiveness of the system. For LinearOpMode the user now must for a telemetry.update() to update the telemetry data on the driver station. This update() mechanism ensures that the driver station gets the updated data properly and at the same time. The Auto Configure function of the Robot Controller is now template based. If there is a commonly used robot configuration, a template can be created so that the Auto Configure mechanism can be used to quickly configure a robot of this type. The logic to detect a runaway op mode (both in the LinearOpMode and OpMode types) and to abort the run, then auto recover has been improved/implemented. Fix has been incorporated so that Logitech F310 gamepad mappings will be correct for Marshmallow users. Release 16.07.08 For the ftc_app project, the gradle files have been modified to support Android Studio 2.1.x. Release 16.03.30 For the MIT App Inventor, the design blocks have new icons that better represent the function of each design component. Some changes were made to the shutdown logic to ensure the robust shutdown of some of our USB services. A change was made to LinearOpMode so as to allow a given instance to be executed more than once, which is required for the App Inventor. Javadoc improved/updated. Release 16.03.09 Changes made to make the FTC SDK synchronous (significant change!) waitOneFullHardwareCycle() and waitForNextHardwareCycle() are no longer needed and have been deprecated. runOpMode() (for a LinearOpMode) is now decoupled from the system's hardware read/write thread. loop() (for an OpMode) is now decoupled from the system's hardware read/write thread. Methods are synchronous. For example, if you call setMode(DcMotorController.RunMode.RESET_ENCODERS) for a motor, the encoder is guaranteed to be reset when the method call is complete. For legacy module (NXT compatible), user no longer has to toggle between read and write modes when reading from or writing to a legacy device. Changes made to enhance reliability/robustness during ESD event. Changes made to make code thread safe. Debug keystore added so that user-generated robot controller APKs will all use the same signed key (to avoid conflicts if a team has multiple developer laptops for example). Firmware version information for Modern Robotics modules are now logged. Changes made to improve USB comm reliability and robustness. Added support for voltage indicator for legacy (NXT-compatible) motor controllers. Changes made to provide auto stop capabilities for op modes. A LinearOpMode class will stop when the statements in runOpMode() are complete. User does not have to push the stop button on the driver station. If an op mode is stopped by the driver station, but there is a run away/uninterruptible thread persisting, the app will log an error message then force itself to crash to stop the runaway thread. Driver Station UI modified to display lowest measured voltage below current voltage (12V battery). Driver Station UI modified to have color background for current voltage (green=good, yellow=caution, red=danger, extremely low voltage). javadoc improved (edits and additional classes). Added app build time to About activity for driver station and robot controller apps. Display local IP addresses on Driver Station About activity. Added I2cDeviceSynchImpl. Added I2cDeviceSync interface. Added seconds() and milliseconds() to ElapsedTime for clarity. Added getCallbackCount() to I2cDevice. Added missing clearI2cPortActionFlag. Added code to create log messages while waiting for LinearOpMode shutdown. Fix so Wifi Direct Config activity will no longer launch multiple times. Added the ability to specify an alternate i2c address in software for the Modern Robotics gyro. Release 16.02.09 Improved battery checker feature so that voltage values get refreshed regularly (every 250 msec) on Driver Station (DS) user interface. Improved software so that Robot Controller (RC) is much more resilient and “self-healing” to USB disconnects: If user attempts to start/restart RC with one or more module missing, it will display a warning but still start up. When running an op mode, if one or more modules gets disconnected, the RC & DS will display warnings,and robot will keep on working in spite of the missing module(s). If a disconnected module gets physically reconnected the RC will auto detect the module and the user will regain control of the recently connected module. Warning messages are more helpful (identifies the type of module that’s missing plus its USB serial number). Code changes to fix the null gamepad reference when users try to reference the gamepads in the init() portion of their op mode. NXT light sensor output is now properly scaled. Note that teams might have to readjust their light threshold values in their op modes. On DS user interface, gamepad icon for a driver will disappear if the matching gamepad is disconnected or if that gamepad gets designated as a different driver. Robot Protocol (ROBOCOL) version number info is displayed in About screen on RC and DS apps. Incorporated a display filter on pairing screen to filter out devices that don’t use the “-“ format. This filter can be turned off to show all WiFi Direct devices. Updated text in License file. Fixed formatting error in OpticalDistanceSensor.toString(). Fixed issue on with a blank (“”) device name that would disrupt WiFi Direct Pairing. Made a change so that the WiFi info and battery info can be displayed more quickly on the DS upon connecting to RC. Improved javadoc generation. Modified code to make it easier to support language localization in the future. Release 16.01.04 Updated compileSdkVersion for apps Prevent Wifi from entering power saving mode removed unused import from driver station Corrrected "Dead zone" joystick code. LED.getDeviceName and .getConnectionInfo() return null apps check for ROBOCOL_VERSION mismatch Fix for Telemetry also has off-by-one errors in its data string sizing / short size limitations error User telemetry output is sorted. added formatting variants to DbgLog and RobotLog APIs code modified to allow for a long list of op mode names. changes to improve thread safety of RobocolDatagramSocket Fix for "missing hardware leaves robot controller disconnected from driver station" error fix for "fast tapping of Init/Start causes problems" (toast is now only instantiated on UI thread). added some log statements for thread life cycle. moved gamepad reset logic inside of initActiveOpMode() for robustness changes made to mitigate risk of race conditions on public methods. changes to try and flag when WiFi Direct name contains non-printable characters. fix to correct race condition between .run() and .close() in ReadWriteRunnableStandard. updated FTDI driver made ReadWriteRunnableStanard interface public. fixed off-by-one errors in Command constructor moved specific hardware implmentations into their own package. moved specific gamepad implemnatations to the hardware library. changed LICENSE file to new BSD version. fixed race condition when shutting down Modern Robotics USB devices. methods in the ColorSensor classes have been synchronized. corrected isBusy() status to reflect end of motion. corrected "back" button keycode. the notSupported() method of the GyroSensor class was changed to protected (it should not be public). Release 15.11.04.001 Added Support for Modern Robotics Gyro. The GyroSensor class now supports the MR Gyro Sensor. Users can access heading data (about Z axis) Users can also access raw gyro data (X, Y, & Z axes). Example MRGyroTest.java op mode included. Improved error messages More descriptive error messages for exceptions in user code. Updated DcMotor API Enable read mode on new address in setI2cAddress Fix so that driver station app resets the gamepads when switching op modes. USB-related code changes to make USB comm more responsive and to display more explicit error messages. Fix so that USB will recover properly if the USB bus returns garbage data. Fix USB initializtion race condition. Better error reporting during FTDI open. More explicit messages during USB failures. Fixed bug so that USB device is closed if event loop teardown method was not called. Fixed timer UI issue Fixed duplicate name UI bug (Legacy Module configuration). Fixed race condition in EventLoopManager. Fix to keep references stable when updating gamepad. For legacy Matrix motor/servo controllers removed necessity of appending "Motor" and "Servo" to controller names. Updated HT color sensor driver to use constants from ModernRoboticsUsbLegacyModule class. Updated MR color sensor driver to use constants from ModernRoboticsUsbDeviceInterfaceModule class. Correctly handle I2C Address change in all color sensors Updated/cleaned up op modes. Updated comments in LinearI2cAddressChange.java example op mode. Replaced the calls to "setChannelMode" with "setMode" (to match the new of the DcMotor method). Removed K9AutoTime.java op mode. Added MRGyroTest.java op mode (demonstrates how to use MR Gyro Sensor). Added MRRGBExample.java op mode (demonstrates how to use MR Color Sensor). Added HTRGBExample.java op mode (demonstrates how to use HT legacy color sensor). Added MatrixControllerDemo.java (demonstrates how to use legacy Matrix controller). Updated javadoc documentation. Updated release .apk files for Robot Controller and Driver Station apps. Release 15.10.06.002 Added support for Legacy Matrix 9.6V motor/servo controller. Cleaned up build.gradle file. Minor UI and bug fixes for driver station and robot controller apps. Throws error if Ultrasonic sensor (NXT) is not configured for legacy module port 4 or 5. Release 15.08.03.001 New user interfaces for FTC Driver Station and FTC Robot Controller apps. An init() method is added to the OpMode class. For this release, init() is triggered right before the start() method. Eventually, the init() method will be triggered when the user presses an "INIT" button on driver station. The init() and loop() methods are now required (i.e., need to be overridden in the user's op mode). The start() and stop() methods are optional. A new LinearOpMode class is introduced. Teams can use the LinearOpMode mode to create a linear (not event driven) program model. Teams can use blocking statements like Thread.sleep() within a linear op mode. The API for the Legacy Module and Core Device Interface Module have been updated. Support for encoders with the Legacy Module is now working. The hardware loop has been updated for better performance.
molyswu / Hand Detectionusing Neural Networks (SSD) on Tensorflow. This repo documents steps and scripts used to train a hand detector using Tensorflow (Object Detection API). As with any DNN based task, the most expensive (and riskiest) part of the process has to do with finding or creating the right (annotated) dataset. I was interested mainly in detecting hands on a table (egocentric view point). I experimented first with the [Oxford Hands Dataset](http://www.robots.ox.ac.uk/~vgg/data/hands/) (the results were not good). I then tried the [Egohands Dataset](http://vision.soic.indiana.edu/projects/egohands/) which was a much better fit to my requirements. The goal of this repo/post is to demonstrate how neural networks can be applied to the (hard) problem of tracking hands (egocentric and other views). Better still, provide code that can be adapted to other uses cases. If you use this tutorial or models in your research or project, please cite [this](#citing-this-tutorial). Here is the detector in action. <img src="images/hand1.gif" width="33.3%"><img src="images/hand2.gif" width="33.3%"><img src="images/hand3.gif" width="33.3%"> Realtime detection on video stream from a webcam . <img src="images/chess1.gif" width="33.3%"><img src="images/chess2.gif" width="33.3%"><img src="images/chess3.gif" width="33.3%"> Detection on a Youtube video.

Using a different version may result in [some errors](https://github.com/tensorflow/models/issues/1581). You may need to [generate your own frozen model](https://pythonprogramming.net/testing-custom-object-detector-tensorflow-object-detection-api-tutorial/?completed=/training-custom-objects-tensorflow-object-detection-api-tutorial/) graph using the [model checkpoints](model-checkpoint) in the repo to fit your TF version. **Content of this document** - Motivation - Why Track/Detect hands with Neural Networks - Data preparation and network training in Tensorflow (Dataset, Import, Training) - Training the hand detection Model - Using the Detector to Detect/Track hands - Thoughts on Optimizations. > P.S if you are using or have used the models provided here, feel free to reach out on twitter ([@vykthur](https://twitter.com/vykthur)) and share your work! ## Motivation - Why Track/Detect hands with Neural Networks? There are several existing approaches to tracking hands in the computer vision domain. Incidentally, many of these approaches are rule based (e.g extracting background based on texture and boundary features, distinguishing between hands and background using color histograms and HOG classifiers,) making them not very robust. For example, these algorithms might get confused if the background is unusual or in situations where sharp changes in lighting conditions cause sharp changes in skin color or the tracked object becomes occluded.(see [here for a review](https://www.cse.unr.edu/~bebis/handposerev.pdf) paper on hand pose estimation from the HCI perspective) With sufficiently large datasets, neural networks provide opportunity to train models that perform well and address challenges of existing object tracking/detection algorithms - varied/poor lighting, noisy environments, diverse viewpoints and even occlusion. The main drawbacks to usage for real-time tracking/detection is that they can be complex, are relatively slow compared to tracking-only algorithms and it can be quite expensive to assemble a good dataset. But things are changing with advances in fast neural networks. Furthermore, this entire area of work has been made more approachable by deep learning frameworks (such as the tensorflow object detection api) that simplify the process of training a model for custom object detection. More importantly, the advent of fast neural network models like ssd, faster r-cnn, rfcn (see [here](https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/detection_model_zoo.md#coco-trained-models-coco-models) ) etc make neural networks an attractive candidate for real-time detection (and tracking) applications. Hopefully, this repo demonstrates this. > If you are not interested in the process of training the detector, you can skip straight to applying the [pretrained model I provide in detecting hands](#detecting-hands). Training a model is a multi-stage process (assembling dataset, cleaning, splitting into training/test partitions and generating an inference graph). While I lightly touch on the details of these parts, there are a few other tutorials cover training a custom object detector using the tensorflow object detection api in more detail[ see [here](https://pythonprogramming.net/training-custom-objects-tensorflow-object-detection-api-tutorial/) and [here](https://towardsdatascience.com/how-to-train-your-own-object-detector-with-tensorflows-object-detector-api-bec72ecfe1d9) ]. I recommend you walk through those if interested in training a custom object detector from scratch. ## Data preparation and network training in Tensorflow (Dataset, Import, Training) **The Egohands Dataset** The hand detector model is built using data from the [Egohands Dataset](http://vision.soic.indiana.edu/projects/egohands/) dataset. This dataset works well for several reasons. It contains high quality, pixel level annotations (>15000 ground truth labels) where hands are located across 4800 images. All images are captured from an egocentric view (Google glass) across 48 different environments (indoor, outdoor) and activities (playing cards, chess, jenga, solving puzzles etc). <img src="images/egohandstrain.jpg" width="100%"> If you will be using the Egohands dataset, you can cite them as follows: > Bambach, Sven, et al. "Lending a hand: Detecting hands and recognizing activities in complex egocentric interactions." Proceedings of the IEEE International Conference on Computer Vision. 2015. The Egohands dataset (zip file with labelled data) contains 48 folders of locations where video data was collected (100 images per folder). ``` -- LOCATION_X -- frame_1.jpg -- frame_2.jpg ... -- frame_100.jpg -- polygons.mat // contains annotations for all 100 images in current folder -- LOCATION_Y -- frame_1.jpg -- frame_2.jpg ... -- frame_100.jpg -- polygons.mat // contains annotations for all 100 images in current folder ``` **Converting data to Tensorflow Format** Some initial work needs to be done to the Egohands dataset to transform it into the format (`tfrecord`) which Tensorflow needs to train a model. This repo contains `egohands_dataset_clean.py` a script that will help you generate these csv files. - Downloads the egohands datasets - Renames all files to include their directory names to ensure each filename is unique - Splits the dataset into train (80%), test (10%) and eval (10%) folders. - Reads in `polygons.mat` for each folder, generates bounding boxes and visualizes them to ensure correctness (see image above). - Once the script is done running, you should have an images folder containing three folders - train, test and eval. Each of these folders should also contain a csv label document each - `train_labels.csv`, `test_labels.csv` that can be used to generate `tfrecords` Note: While the egohands dataset provides four separate labels for hands (own left, own right, other left, and other right), for my purpose, I am only interested in the general `hand` class and label all training data as `hand`. You can modify the data prep script to generate `tfrecords` that support 4 labels. Next: convert your dataset + csv files to tfrecords. A helpful guide on this can be found [here](https://pythonprogramming.net/creating-tfrecord-files-tensorflow-object-detection-api-tutorial/).For each folder, you should be able to generate `train.record`, `test.record` required in the training process. ## Training the hand detection Model Now that the dataset has been assembled (and your tfrecords), the next task is to train a model based on this. With neural networks, it is possible to use a process called [transfer learning](https://www.tensorflow.org/tutorials/image_retraining) to shorten the amount of time needed to train the entire model. This means we can take an existing model (that has been trained well on a related domain (here image classification) and retrain its final layer(s) to detect hands for us. Sweet!. Given that neural networks sometimes have thousands or millions of parameters that can take weeks or months to train, transfer learning helps shorten training time to possibly hours. Tensorflow does offer a few models (in the tensorflow [model zoo](https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/detection_model_zoo.md#coco-trained-models-coco-models)) and I chose to use the `ssd_mobilenet_v1_coco` model as my start point given it is currently (one of) the fastest models (read the SSD research [paper here](https://arxiv.org/pdf/1512.02325.pdf)). The training process can be done locally on your CPU machine which may take a while or better on a (cloud) GPU machine (which is what I did). For reference, training on my macbook pro (tensorflow compiled from source to take advantage of the mac's cpu architecture) the maximum speed I got was 5 seconds per step as opposed to the ~0.5 seconds per step I got with a GPU. For reference it would take about 12 days to run 200k steps on my mac (i7, 2.5GHz, 16GB) compared to ~5hrs on a GPU. > **Training on your own images**: Please use the [guide provided by Harrison from pythonprogramming](https://pythonprogramming.net/training-custom-objects-tensorflow-object-detection-api-tutorial/) on how to generate tfrecords given your label csv files and your images. The guide also covers how to start the training process if training locally. [see [here] (https://pythonprogramming.net/training-custom-objects-tensorflow-object-detection-api-tutorial/)]. If training in the cloud using a service like GCP, see the [guide here](https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/running_on_cloud.md). As the training process progresses, the expectation is that total loss (errors) gets reduced to its possible minimum (about a value of 1 or thereabout). By observing the tensorboard graphs for total loss(see image below), it should be possible to get an idea of when the training process is complete (total loss does not decrease with further iterations/steps). I ran my training job for 200k steps (took about 5 hours) and stopped at a total Loss (errors) value of 2.575.(In retrospect, I could have stopped the training at about 50k steps and gotten a similar total loss value). With tensorflow, you can also run an evaluation concurrently that assesses your model to see how well it performs on the test data. A commonly used metric for performance is mean average precision (mAP) which is single number used to summarize the area under the precision-recall curve. mAP is a measure of how well the model generates a bounding box that has at least a 50% overlap with the ground truth bounding box in our test dataset. For the hand detector trained here, the mAP value was **0.9686@0.5IOU**. mAP values range from 0-1, the higher the better. <img src="images/accuracy.jpg" width="100%"> Once training is completed, the trained inference graph (`frozen_inference_graph.pb`) is then exported (see the earlier referenced guides for how to do this) and saved in the `hand_inference_graph` folder. Now its time to do some interesting detection. ## Using the Detector to Detect/Track hands If you have not done this yet, please following the guide on installing [Tensorflow and the Tensorflow object detection api](https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md). This will walk you through setting up the tensorflow framework, cloning the tensorflow github repo and a guide on - Load the `frozen_inference_graph.pb` trained on the hands dataset as well as the corresponding label map. In this repo, this is done in the `utils/detector_utils.py` script by the `load_inference_graph` method. ```python detection_graph = tf.Graph() with detection_graph.as_default(): od_graph_def = tf.GraphDef() with tf.gfile.GFile(PATH_TO_CKPT, 'rb') as fid: serialized_graph = fid.read() od_graph_def.ParseFromString(serialized_graph) tf.import_graph_def(od_graph_def, name='') sess = tf.Session(graph=detection_graph) print("> ====== Hand Inference graph loaded.") ``` - Detect hands. In this repo, this is done in the `utils/detector_utils.py` script by the `detect_objects` method. ```python (boxes, scores, classes, num) = sess.run( [detection_boxes, detection_scores, detection_classes, num_detections], feed_dict={image_tensor: image_np_expanded}) ``` - Visualize detected bounding detection_boxes. In this repo, this is done in the `utils/detector_utils.py` script by the `draw_box_on_image` method. This repo contains two scripts that tie all these steps together. - detect_multi_threaded.py : A threaded implementation for reading camera video input detection and detecting. Takes a set of command line flags to set parameters such as `--display` (visualize detections), image parameters `--width` and `--height`, videe `--source` (0 for camera) etc. - detect_single_threaded.py : Same as above, but single threaded. This script works for video files by setting the video source parameter videe `--source` (path to a video file). ```cmd # load and run detection on video at path "videos/chess.mov" python detect_single_threaded.py --source videos/chess.mov ``` > Update: If you do have errors loading the frozen inference graph in this repo, feel free to generate a new graph that fits your TF version from the model-checkpoint in this repo. Use the [export_inference_graph.py](https://github.com/tensorflow/models/blob/master/research/object_detection/export_inference_graph.py) script provided in the tensorflow object detection api repo. More guidance on this [here](https://pythonprogramming.net/testing-custom-object-detector-tensorflow-object-detection-api-tutorial/?completed=/training-custom-objects-tensorflow-object-detection-api-tutorial/). ## Thoughts on Optimization. A few things that led to noticeable performance increases. - Threading: Turns out that reading images from a webcam is a heavy I/O event and if run on the main application thread can slow down the program. I implemented some good ideas from [Adrian Rosebuck](https://www.pyimagesearch.com/2017/02/06/faster-video-file-fps-with-cv2-videocapture-and-opencv/) on parrallelizing image capture across multiple worker threads. This mostly led to an FPS increase of about 5 points. - For those new to Opencv, images from the `cv2.read()` method return images in [BGR format](https://www.learnopencv.com/why-does-opencv-use-bgr-color-format/). Ensure you convert to RGB before detection (accuracy will be much reduced if you dont). ```python cv2.cvtColor(image_np, cv2.COLOR_BGR2RGB) ``` - Keeping your input image small will increase fps without any significant accuracy drop.(I used about 320 x 240 compared to the 1280 x 720 which my webcam provides). - Model Quantization. Moving from the current 32 bit to 8 bit can achieve up to 4x reduction in memory required to load and store models. One way to further speed up this model is to explore the use of [8-bit fixed point quantization](https://heartbeat.fritz.ai/8-bit-quantization-and-tensorflow-lite-speeding-up-mobile-inference-with-low-precision-a882dfcafbbd). Performance can also be increased by a clever combination of tracking algorithms with the already decent detection and this is something I am still experimenting with. Have ideas for optimizing better, please share! <img src="images/general.jpg" width="100%"> Note: The detector does reflect some limitations associated with the training set. This includes non-egocentric viewpoints, very noisy backgrounds (e.g in a sea of hands) and sometimes skin tone. There is opportunity to improve these with additional data. ## Integrating Multiple DNNs. One way to make things more interesting is to integrate our new knowledge of where "hands" are with other detectors trained to recognize other objects. Unfortunately, while our hand detector can in fact detect hands, it cannot detect other objects (a factor or how it is trained). To create a detector that classifies multiple different objects would mean a long involved process of assembling datasets for each class and a lengthy training process. > Given the above, a potential strategy is to explore structures that allow us **efficiently** interleave output form multiple pretrained models for various object classes and have them detect multiple objects on a single image. An example of this is with my primary use case where I am interested in understanding the position of objects on a table with respect to hands on same table. I am currently doing some work on a threaded application that loads multiple detectors and outputs bounding boxes on a single image. More on this soon.

gionanide / Speech Signal Processing And ClassificationFront-end speech processing aims at extracting proper features from short- term segments of a speech utterance, known as frames. It is a pre-requisite step toward any pattern recognition problem employing speech or audio (e.g., music). Here, we are interesting in voice disorder classification. That is, to develop two-class classifiers, which can discriminate between utterances of a subject suffering from say vocal fold paralysis and utterances of a healthy subject.The mathematical modeling of the speech production system in humans suggests that an all-pole system function is justified [1-3]. As a consequence, linear prediction coefficients (LPCs) constitute a first choice for modeling the magnitute of the short-term spectrum of speech. LPC-derived cepstral coefficients are guaranteed to discriminate between the system (e.g., vocal tract) contribution and that of the excitation. Taking into account the characteristics of the human ear, the mel-frequency cepstral coefficients (MFCCs) emerged as descriptive features of the speech spectral envelope. Similarly to MFCCs, the perceptual linear prediction coefficients (PLPs) could also be derived. The aforementioned sort of speaking tradi- tional features will be tested against agnostic-features extracted by convolu- tive neural networks (CNNs) (e.g., auto-encoders) [4]. The pattern recognition step will be based on Gaussian Mixture Model based classifiers,K-nearest neighbor classifiers, Bayes classifiers, as well as Deep Neural Networks. The Massachussets Eye and Ear Infirmary Dataset (MEEI-Dataset) [5] will be exploited. At the application level, a library for feature extraction and classification in Python will be developed. Credible publicly available resources will be 1used toward achieving our goal, such as KALDI. Comparisons will be made against [6-8].

Turtle Graphics - This is a common project where you create a floor of 20 x 20 squares. Using various commands you tell a turtle to draw a line on the floor. You have moved forward, left or right, lift or drop the pen, etc. Do a search online for "Turtle Graphics" for more information. Optional: Allow the program to read in the list of commands from a file. GIF Creator A program that puts together multiple images (PNGs, JPGs, TIFFs) to make a smooth GIF that can be exported. Optional: Make the program convert small video files to GIFs as well. Security Caesar cipher - Implement a Caesar cipher, both encoding, and decoding. The key is an integer from 1 to 25. This cipher rotates the letters of the alphabet (A to Z). The encoding replaces each letter with the 1st to 25th next letter in the alphabet (wrapping Z to A). So key 2 encrypts "HI" to "JK", but key 20 encrypts "HI" to "BC". This simple "monoalphabetic substitution cipher" provides almost no security, because an attacker who has the encoded message can either use frequency analysis to guess the key, or just try all 25 keys.

Their identity is checked and their billing process reviewed.' versions: free-pro-team: '*' --- ### About verified creators A verified creator is an organization that {% data variables.product.company_short %} has checked. Anyone can share their apps with other users on {% data variables.product.prodname_marketplace %} but only organizations that are verified by {% data variables.product.company_short %} can sell apps. For more information about organizations, see "[About organizations](/github/setting-up-and-managing-organizations-and-teams/about-organizations)." The verification process aims to protect users. For example, it verifies the seller's identity, checks that their {% data variables.product.product_name %} organization is set up securely, and that they can be contacted for support. After passing the verification checks, any apps that the organization lists on {% data variables.product.prodname_marketplace %} are shown with a verified creator badge {% octicon "verified" aria-label="Verified creator badge" %}. The organization can now add paid plans to any of their apps. Each app with a paid plan also goes through a financial onboarding process to check that it's set up to handle billing correctly.  In addition to the verified creator badge, you'll also see badges for unverified and verified apps. These apps were published using the old method for verifying individual apps.  For information on finding apps to use, see "[Searching {% data variables.product.prodname_marketplace %}](/github/searching-for-information-on-github/searching-github-marketplace)." ### About the verification process The first time you request verification for a listing of one of your apps, you will enter the verification process. An onboarding expert will guide you through the process. This includes checking: - Profile information - The basic profile information is populated accurately and appropriately. - Security - The organization has enabled two-factor authentication. - Verified domain - The organization has verified the domain of the site URL. - Purchase webhook event - The event is handled correctly by the app. When your organization is verified, all your apps are shown with a verified creator badge. You are now able to offer paid plans for any of your apps. For more information about the requirements for listing an app on {% data variables.product.prodname_marketplace %}, see "[Requirements for listing an app on {% data variables.product.prodname_marketplace %}](/marketplace/getting-started/requirements-for-listing-an-app-on-github-marketplace/)." {% data reusables.marketplace.app-transfer-to-org-for-verification %} For information on how to do this, see: "[Submitting your listing for publication](/developers/github-marketplace/submitting-your-listing-for-publication#transferring-an-app-to-an-organization-before-you-submit)." {% note %} **Note:** This verification process for apps replaces the previous process where individual apps were verified.

See "[Differences between GitHub Apps and OAuth Apps](/apps/differences-between-apps/)" for more details. - Apps should use the principle of least privilege and should only request the OAuth scopes and GitHub App permissions that the app needs to perform its intended functionality. For more information, see [Principle of least privilege](https://en.wikipedia.org/wiki/Principle_of_least_privilege) in Wikipedia. - Apps should provide customers with a way to delete their account, without having to email or call a support person. - Apps should not share tokens between different implementations of the app. For example, a desktop app should have a separate token from a web-based app. Individual tokens allow each app to request the access needed for GitHub resources separately. - Design your app with different user roles, depending on the functionality needed by each type of user. For example, a standard user should not have access to admin functionality, and billing managers might not need push access to repository code. - Apps should not share service accounts such as email or database services to manage your SaaS service. - All services used in your app should have unique login and password credentials. - Admin privilege access to the production hosting infrastructure should only be given to engineers and employees with administrative duties. - Apps should not use personal access tokens to authenticate and should authenticate as an [OAuth App](/apps/about-apps/#about-oauth-apps) or a [GitHub App](/apps/about-apps/#about-github-apps): - OAuth Apps should authenticate using an [OAuth token](/apps/building-oauth-apps/authorizing-oauth-apps/). - GitHub Apps should authenticate using either a [JSON Web Token (JWT)](/apps/building-github-apps/authenticating-with-github-apps/#authenticating-as-a-github-app), [OAuth token](/apps/building-github-apps/identifying-and-authorizing-users-for-github-apps/), or [installation access token](/apps/building-github-apps/authenticating-with-github-apps/#authenticating-as-an-installation). ### Data protection - Apps should encrypt data transferred over the public internet using HTTPS, with a valid TLS certificate, or SSH for Git. - Apps should store client ID and client secret keys securely. We recommend storing them as [environmental variables](http://en.wikipedia.org/wiki/Environment_variable#Getting_and_setting_environment_variables). - Apps should delete all GitHub user data within 30 days of receiving a request from the user, or within 30 days of the end of the user's legal relationship with GitHub. - Apps should not require the user to provide their GitHub password. - Apps should encrypt tokens, client IDs, and client secrets. ### Logging and monitoring Apps should have logging and monitoring capabilities. App logs should be retained for at least 30 days and archived for at least one year. A security log should include: - Authentication and authorization events - Service configuration changes - Object reads and writes - All user and group permission changes - Elevation of role to admin - Consistent timestamping for each event - Source users, IP addresses, and/or hostnames for all logged actions ### Incident response workflow To provide a secure experience for users, you should have a clear incident response plan in place before listing your app. We recommend having a security and operations incident response team in your company rather than using a third-party vendor. You should have the capability to notify {% data variables.product.product_name %} within 24 hours of a confirmed incident. For an example of an incident response workflow, see the "Data Breach Response Policy" on the [SANS Institute website](https://www.sans.org/information-security-policy/). A short document with clear steps to take in the event of an incident is more valuable than a lengthy policy template. ### Vulnerability management and patching workflow You should conduct regular vulnerability scans of production infrastructure. You should triage the results of vulnerability scans and define a period of time in which you agree to remediate the vulnerability. If you are not ready to set up a full vulnerability management program, it's useful to start by creating a patching process.

Discussions are for conversations that need to be transparent and accessible but do not need to be tracked on a project board and are not related to code, unlike issues. Discussions enable fluid, open conversation in a public forum. Discussions give a space for more collaborative conversations by connecting and giving a more centralized area to connect and find information. ### Enabling {% data variables.product.prodname_discussions %} on your repository Repository owners and people with write access can enable {% data variables.product.prodname_discussions %} for a community on their public repositories. When you first enable a {% data variables.product.prodname_discussions %}, you will be invited to configure a welcome post. {% data reusables.repositories.navigate-to-repo %} 1.

Click **Start discussion**.  ### Welcoming contributions to your discussions You can welcome your community and introduce a new way to communicate in a repository by creating a welcome post and pin the post to your {% data variables.product.prodname_discussions %} page. Pinning and locking discussions helps people know that a post is meant as an announcement. You can use announcements as a way to link people to more resources and offer guidance for opening discussions in your community. For more information about pinning a discussion, see "[Managing discussions in your repository](/discussions/managing-discussions-for-your-community/managing-discussions-in-your-repository#pinning-a-discussion)." ### Setting up community guidelines for contributors You can set contributing guidelines to encourage collaborators to have meaningful, useful conversations that are relevant to the repository. You can also update the repository's README to communicate expectations on when collaborators should open an issue or discussion. For more information about providing guidelines for your project, see "[Adding a code of conduct to your project](/github/building-a-strong-community/adding-a-code-of-conduct-to-your-project)" and "[Setting up your project for healthy contributions](/github/building-a-strong-community/setting-up-your-project-for-healthy-contributions)." ### Creating a new discussion Anyone with access to a repository can create a discussion. {% data reusables.discussions.starting-a-discussion %} ### Organizing discussions into relevant categories Repository owners and people with write access can create new categories to keep discussions organized. Collaborators participating and creating new discussions can group discussions into the most relevant existing categories. Discussions can also be recategorized after they are created. For more information, see "[Managing categories for discussions in your repository](/discussions/managing-discussions-for-your-community/managing-categories-for-discussions-in-your-repository)" ### Promoting healthy conversations People with write permissions for a repository can help surface important conversations by pinning discussions, deleting discussions that are no longer useful or are damaging to the community, and transferring discussions to more relevant repositories owned by the organization. For more information, see "[Managing discussions in your repository](/discussions/managing-discussions-for-your-community/managing-discussions-in-your-repository)." People with triage permissions for a repository can help moderate a project's discussions by marking comments as answers, locking discussions that are not longer useful or are damaging to the community, and converting issues to discussions when an idea is still in the early stages of development. For more information, see "[Moderating discussions](/discussions/managing-discussions-for-your-community/moderating-discussions)." ### Next steps Once there is a clear path to scope work out and move an idea from concept to reality, you can create an issue and start tracking your progress.
