Beef Bonk

Beef Bonk (voiced by John Stephenson) is the school bully and main antagonist of the series. He only has two friends, Rotten Roland and Earl Eccchhh. The three of them are known as the Bonk Bunch, of which he is the leader. He looks like a rooster. Beef has a strong hatred for Earth, often claiming that "Earth Stinks", although he seems to have a hatred for all planets except his homeworld (which is neither identified or has ever appeared in the series), as he has made other remarks as "Mars Stinks". Beef loves being angry more than anything, as evidenced in the episode The Martian Mumps, as he suffered the titular disease. Whenever Beef gets mad, he turns blue, his eyes turns red and steams comes out of the three holes on both sides of his neck. Beef is an expert at the hockey-like game of Zuggleball. His father, Biff Bonk, appeared in Founders Day.
