Four-Armageddon appeared in the episode "Really Real Wrestling" as the main antagonist of the three. He feels offended when he heard Mordecai and Rigby said that wrestling was fake. He believes that wrestling is real and beat up Mordecai and Rigby, and is later defeated by Pops (and as a result, loses his championship). He has hands instead of feet that make him walk. They were all beaten all the way to death.
As his name implies, he has four powerful arms. He wears a red speedo and has long light blond hair.
