Bob Saget

From UnMarioWiki

Bob Saget is a well-known actor and comedian. Few people know that he is actually the devil. Several people, such as Bowser, Evil Guy, Birdo, 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.

As Saget wishes to rule the UnWorld, he is the archenemy of Bill Cosby.
