Fishface is an antagonist of the Teenage Mutant Ninja Turtles. Formerly known as Xever Montes, he was a Brazilian street urchin who was left to roam the criminal underworld of São Paulo, eventually being recruited by the Shredder after attempting to steal something belonging to him. He later mutated into the mutant snake-head Fishface after touching a snakehead in a Chinatown marketplace. Following the mutation, he wears a water-breathing rig and mechanical legs developed by Baxter Stockman. He eventually leaves the Foot in the fifth season.
