Professor Chaos

Professor Chaos is the villainous alter-ego of Butters from South Park which is a parody of Doctor Doom and is in many ways a childish attempt to vent frustration at the world, though he geniunely believes he is a substantial threat: in reality Professor Chaos is a very inept villain who rarely causes much havoc in the town (except maybe in his own fantasy world).

In fact the Professor Chaos persona has even managed to get Butters into trouble, such as when he (in)famously got a shuriken to his eye playing a "game" with the other boys - where he had delusions of being a real supervillain (drawn in a classic "anime" style). In a later episode, he joins the Legion of Doom.
