He was apparently a victim of the Virus and was desperate to cure it. He was responsible for the death of the Unknown Goodfella. He joined the badfellas to find a cure for the Virus but was later turned into a scarecrow by the Scot.
A Super-Smart alien from the planet Zog, he was killed when Strongarm cut his pony tail off. Turns out he was just as dumb as everyone else.
He was a normal guy until Crazi Stan accidently hit him with a crazy-ray-inator. This made him a psycotic lunatic, and his insanity soon led him to fall off a skyscraper. Hmm.
Apparently he's the leader, but he is by far the most insane. The Scot shot him through the head with a bow and arrow in a duel, but three-fingered Johnny also managed to shoot the Scot with a reversal ray.
After the deaths of all the Badfellas, their bodies were collected and resurrected as zombies by Bitch Machine, however, they were all re-killed by Shirazzle Dazzle and his minions in the Battle of the Luna Library.
