Buffalo Mutant

Buffalo Mutant (バッファロー怪人) (26) - A buffalo monster. It can possess someone, headbutt, and has super strength. 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 Buffalo Mutant to break the trust within humans. After Buffalo Mutant beat up one of the kids that mocked her, Buffalo Mutant started to concern her parents which is when Buffalo Mutant took action. In the form of a man, Buffalo Mutant told her that adults cannot be trusted. When it came out of Mami, Kotaro 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 Buffalo Mutant out after stepping on a fallen electric wire. Kotaro transforms into Kamen Rider BLACK and chopped off Buffalo Mutant's horns. Buffalo Mutant was killed by the Rider Kick.
