Fake Brother

In the story mode of the Super NES version of TMNT Tournament Fighters, the player will encounter a "mirror match" against their chosen Turtle. This Turtle will have a different palette than either of the selectable versions, with purple skin, a blue plastron, and brown bandana and joint pads. This evil turtle is only ever referred to as a "Fake Bro." and its origins are unknown. Popular theory holds that it's a returning Mechaturtle, but nothing in-game supports this. It's also unknown if these are four "Fake Bros." or just one which switches weapons and tactics.
