Big Chuck Smith was an Irish heavyweight/cruiserweight boxer that once fought Rocky Balboa. He appears in the 1988 Rocky arcade video game and 2002's Rocky Legends video game. Chuck is described as a formidable fighter and relatively quick for his size, with explosive power in both fists "with a rock-hard chin". He was one of the many heard but not seen fighters from the introduction to Rocky III during the fight montage that quickly had it's clock cleaned by Clubber Lang.
He was the former Cruiserweight Champion, but he moved up to Heavyweight in 1972 and won the Irish heavyweight title. He retired after his loss to Rocky Balboa.
