The Ultimate Slayer serves as the penultimate boss of Teenage Mutant Ninja Turtles 3: Mutant Nightmare's second chapter, "Bishop's Gambit". It also appears as a recurring boss in the DS version, at one point fighting alongside Agent Bishop himself. Although The Ultimate Slayer would go on to become Rat King in the cartoon, he never does so in the games.
