Principal Madman is the Adolf Hitler inspired dictator principal of Polyneaux Middle School. His temper is usually unmatched, until he runs into one of The Jones Family. He is not an unfair principal, only a temperamental one. He is also immature and extremely tyrannical towards his students (especially Robot Jones), and treats his staff quite harshly as well. He has punished The Yogmans for infecting Robot as well as Mr. Mitchell's computer. He is very paranoid of germs, including Influenza. He also believed he was infected with a computer virus when Robot Jones sneezed on him. Madman found himself to be operating much more efficiently and decided to dress and act as a robot. His other attire consists of dark green sweaters. He is a large principal and is prone to snacking. In the Robot Jones promotional, he is said to be one of the antagonists with the mission to take Robot Jones down.
