Buffalo Mutant

The Buffalo Mutant appeared in 1988 TV series called Kamen Rider Black. The Buffalo Mutant (バッファロー怪人 Baffarō Kajin) is a buffalo Gorgom monster.

The Buffalo Mutant was used by Gorgom in order to possess a girl named Mami so she can be good at sports like baseball and soccer when Gorgom used the Buffalo Mutant to break the trust within humans. After Buffalo Mutant beat up one of the kids that mocked her, the Buffalo Mutant started to concern her parents which is when the Buffalo Mutant took action. In the form of a man, the Buffalo Mutant told her that adults cannot be trusted. When it came out of Mami, Kohtaro became Kamen Rider Black and attacked (even when it repossessed Mami). It gave Kamen Rider Black a disadvantage with Mami possessed by it. In the second battle near a factory, Mami was able to get the Buffalo Mutant out after stepping on a fallen electric wire. Kohtaro transforms into Kamen Rider Black and chopped off the Buffalo Mutant's horns and then the Buffalo Mutant was killed by the Rider Kick.
