Fuckwit was the result of a failed genetic experiment by The Professor. Originally Fuckwit was meant to act as an absolute equal to the world's greatest superhero at the time, instead he became the physical equivalent of Superman but the mental equivalent of an infant. He's often referred to by other villains as having downs syndrome. The Professor still finds good use for Fuckwit in the henchmen's unwaivering loyalty and willingness to follow any order. However the order must be given in negative connotation for Fuckwit to understand them. The Professor states at one point that "damn backwards talk is driving me crazy".
For the majority of his time in the series, Fuckwit acted as a guard in the headquarters of the American Fraternity and was sometimes seen out serving as personal bodyguard and chauffeur to the Professor. When Mister Rictus implements his plan to resurface The Fraternity and name himself and Mr. Future the criminal overlords of the world, Fuckwit is drained of his superhuman abilities by Sucker and beaten to death with a crowbar by Johnny Two Dicks
