Garrett Bobby Ferguson

Garrett Bobby Ferguson (G.B.F.), also incorrectly referred to as Giant Bearded Face, is the main antagonist who appears in the episode High Score and is from outer space. He appears to be a floating head with long hair and a beard who can grow arms and legs. He was also the universe record holder for an arcade game called Broken Bonez, until he was dethroned by Mordecai and Rigby, causing him to die in an explosion of goo. He is a parody of the world renowned videogame highscore champion Billy Mitchell, who currently holds the record for playing a perfect game of Pac-Man.
