Big Billy is one of the members of The Gangreen Gang (a gang of monstrous teenaged hoodlums that are green-skinned and disreputable and unhealthy looking (as if suffering from gangrene). Billy is a hulking, fat cyclops with a shock of red hair covering the top half of his face with a single big blue eye underneath. Billy acts as the Gang's muscle. Big Billy's height is 6'11" tall and weights 1014.1 pounds. Though he does at times display a childlike innocence, he mostly just does the bidding of his more savvy and vindictive friends. His real name is William W. Williams. Big Billy loves to eat and will gobble more junk than the rest of the gang. In one episode, he was saved by the Powerpuff Girls and began following them everywhere out of sheer gratitude, but eventually he became more of a hindrance than a help. He's the same age as Snake and Grubber- the middle-aged members of the Gang.
