Bob Saget, a man with a dream.
Robert "Bob" Saget or "Satan" is a well-known actor. Several people, such as Bowser and George W. Bush have sold their souls to him, meaning that Bob Saget is really the evil behind the evil. While he is not serving his position as ruler of Hell, Bob shares a bitter rivalry with the equally evil Princess Daisy.
Kirby was once his right hand man, when he swallowed people's nightmares for no reason, thus creating Nightmare. Dora the Explorer eventually replaced Kirby, and is much more efficient.
As Saget wishes to rule the UnWorld, he is the archenemy of Bill Cosby. Jebus Khrist once battled him, but Bob Saget pwned him. Badly. He also appeared in Mario Tag.
Ronald McDonald is his arch-nemesis, as they were roomates in College and had a bajillion children. Saget took half, while he ate the other half. Saget had an epic battle with Ronald, and Saget ate his ears and face and internal organs out, thus having to paint Ronald's face white.

Once, Nobunaga Oda took over as ruler of Hell, because he's the Devil King. Bob Saget was notably pissed off and decided to send Evil Snowmen into Hell, but they melted before they could do anything. He eventually bribed Nobunga to give him back rule over Hell with Candee.
Margaret Thatcher is his current right-hand woman.
