Self-proclaimed “Evil Boy Genius” with a dream to rule the world since the Second Grade. He specializes in robotics and controls his own robotic army. Jack lives in his wealthy parents' basement, which he uses as his "secret" lab. Despite his genius and technological prowess, he is very clumsy, goofy, and immature, and has little common sense. Despite his frequent defeats, he was often over-confident in his own "genius". Jack is very fearful, paranoid, and neurotic; if he found himself in danger, his confidence slipped, and he often panicked. Jack also doesn't do well in enclosed spaces and had an extreme fear of rejection and failure. His motivation for world-domination was to compensate for his own feelings of worthlessness.
