Evil Jimmy was one of Jimmy's clones created in the "Send in the Clones" episode. He was the last of the 6 clones created to do chores for Jimmy, though he was the one that was Jimmy's moral opposite and he caused trouble and tried to trick the other the clones that he's the real Jimmy, but that backfired when Jimmy iced his clones. Unfortunately, Evil Jimmy managed to escape on Jimmy's jetpack before Jimmy could stop him, leaving the real Jimmy in big trouble with his friends, despite the fact that Jimmy didn't do anything wrong.
