This turtle is a member of the Shredder Elite and is sometimes be holding Splinter captive in the randomized story mode. This evil turtle is only ever referred to as a "Fake Brother" and its origins are unknown, though the victorious Ninja Turtle sometimes refers to it as a knock off of the real thing. Popular theory holds that it's a returning Mechaturtle, but nothing in-game supports this. It's also unknown if these are four "Fake Brothers" or just one which switches weapons and tactics. It is not possible to play the game using the "Fake Brother" palette or portrait, making him the only unplayable character in the game.
