Fishface Fishface is a Teenage Mutant Ninja Turtles minifigure released in 2013 . Description . Fishface consists of five parts . The first is dark pink and is shaped like a large , mutated fish . The piece has small , yellow eyes , large , sharp teeth , and an orange breathing system . The piece also has a large fin that has a chunk missing and a long tail . He has two light pink arms on each side of his body . He also has two ridged , metal legs that are exclusive to his figure . Background . Born in 1990 in Sao Paulo , Xever Montes was orphaned at a young age and grew up on the city streets , stealing to survive . One day he attempted to steal a briefcase from a hotel room , but was caught and imprisoned . However , the owner of the briefcase , Oroku Saki ( best known as " the Shredder " ) , found Montes ' s skills may be useful to the Foot Clan , so he bailed the street thug out and employed him for dirtier jobs such as major theft and assassinations . During his employment , Montes formed a rivalry with Shredder ' s star pupil , Chris Bradford . In the episode " New Friend , Old Enemy " , when Shredder discovered his old enemy Splinter was in New York and had a clan , he traveled there and ordered Montes to assist Bradford in finding Splinter and the turtles . Many unsuccessful attempts were made . In one attempt in the episode " The Guantlet " , Montes and Bradford were cornered by the turtles . In an effort to take the turtles down with him , Bradford stabbed a tank of mutagen , but this instead had the stream of mutagen spurting from the bomb miss the turtles and hit Bradford and Montes , turning Montes into a large mutant snakehead - like creature with powerful stick - like arms , fangs carrying a venom that produces fever , nausea and hallucinations , aquatic breathing and superhuman swimming speed ( due to him previously holding an exotic pink snakehead at a Chinatown market stall ) . Montes ' s legs were lost in the mutation , so Shredder , seeing that he was useless to him if he could only fight in water , employed Baxter Stockman to build him bionic legs and a breathing apparatus . In the episode " The Alien Agenda " , Stockman struggled at first , but then Karai brought him some stolen Kraang technology , which Stockman used which to give Montes better control over his legs . When the turtles see Montes in his new form in the episode " The Pulverizer " , they just laughed at him , and he was given the name " Fishface " by Michelangelo , but they soon realize what they were up against when Fishface kicked Michelangelo into the wall and bit Raphael in the shoulder . He was defeated when Donatello came barging in with the Shellraiser and blasted him away with a trash - ball cannon . In " Baxter ' s Gambit " , Stockman trapped the turtles , Fishface and Dogpound in a giant deadly labyrinth , but they managed to escape and reach Stockman , who then escaped in return at the last minute . In the episode " Showdown " , when Splinter came to rescue April O ' Neil from Shredder ' s clutches , he easily defeated Fishface by knocking him into the water and letting him retreat with Dogpound . In the episode " Mikey Gets Shellacne " , Fishface witnessed Dogpound getting mutated by Stockman ' s mutagen supply int Rahzar and got electrocuted by Michelangelo . In the episode " Wormquake " , he unveiled a new weapon to Raphael : a larger butterfly knife called a balisword . He is one of Raphael ' s arch - enemies , alongside Spider Bytez .
