Satan is seen at the end of every episode that features MC Pee Pants. He then blasts fire at him, and forces him to play his addicting song I Want Candy. He only makes one appearance, at the end of The Episode MC Pee Pants, in which he appears to be taken from a Hannah-Barbera cartoon. After he is seen here, he is never shown again unless heard from off-screen. Matt Maiellaro stated that they showed him in his first episode because they believed the show would not last long. His appearance, keeping with Adult Swim's original theme, was ripped directly from Hanna Barbera.
