McChickenhead

 

Shamus O'Rielly lived a deplorable life filled with crime and violence as a low level thug in the Irish Mafia, until one day when he woke up to discover his head had transformed into a giant chicken leg, apparently the result of an old Romani woman's curse inflicted upon him in an act of revenge. Branded a freak and ostracized from his gang McChikenhead used his strange chicken-leg powers to gain revenge on those who betrayed him. 

SnailFace

The disgusting mutant known as SnailFace was originally a thief and petty thug, who attempted to break into the Cristix corporation labs to steal industrial secrets. A one-in-a-million accident with a top secret radioactive formula resulted in his present hideous mutation. SnailFace possesses superhuman strength, and his rubbery body resists blunt-force injury, even deflecting bullets of low caliber. SnailFace has since moved up in the criminal underworld.
