"Stone Cold" Steve Austin (voiced by himself) is a WWE wrestler and one of the main characters in Celebrity Deathmatch. He sort of acts as the show's scientist, making things like giant gundam-like robots, mutated super freaks, etc. He doesn't appear in the revival of the show, for once Nick mentioned he was too expensive.
