The Butcher is a pet available in Diablo III for those who complete the Anniversary Dungeon (specifically, it must be completed by a fresh character of level 1 at the moment of entering the cathedral, in one continuous solo run, without resetting the game).
He has been described as a "baby Butcher." He carries his cleaver in one hand, and a piece of meat in the other that he chews on.
He may be little, but he is fierce.
