Sideshow Bob

Sideshow Bob is one of the villains on The Simpsons. His real name is Robert Underdunk Terwilliger. He mainly is evil because he has a lasting goal of killing Bart Simpson (and if including Bart's family too) as revenge for exposing his crime in framing Krusty the Klown, because in turn, he wanted revenge on Krusty the Clown because all Bob was necessary for Krusty was to act like a non-speaking idiot who gets injured and faces cruelty from clown-pranks.

He used to be Krusty the Clown's sidekick and best friend, but in 1990 he was so tired of acting like an idiot that he framed Krusty for robbing the Kwik-E-Mart. Fortunately, for Krusty, Bart foiled his scheme and put him in jail. Sideshow Bob had only one thing on his mind: Bart's death. For his next evil plan, he married Bart's Aunt Selma and tried to blow her up. He also rigged an election against Mayor Quimby, stole an A-bomb, and hypnotized Bart into killing Krusty. But there were some good things he did. For example, when he and Bart had to work together to foil Bob's brother, Cecil. He also helped Homer catch someone who was trying to kill him. Later on, Bob ran away to Italy and married a Italian woman named Francesca. He also got a son named Gino. The family now has a vendetta against the Simpsons.
