Mean "Mean Machine" Angel is a member of the Angel Gang and one of the sons of Elmer "Pa" Angel. He is nicknamed "Butting Man" for his favourite attack, a vicious headbutt with his metal plate. His famous dial has four settings: 1, where he's surly and disagreeable; 2, where he's mean; 3, where he's vicious; and 4, which is when he is fully berserk. On occasion, an extremely hard headbutt causes Mean Machine's dial to get stuck on 4½, which causes him to go berserk, unable to stop headbutting anything he comes across.
