Kinnikuman Generations Buffaloman Finisher

i swear this guy isnt buffalo man. buffaloman has 2 horns not one

I believe Buffaloman loses and regrows his horn multiple times throughout the series. He first loses his horn fighting Warsman which he then kills.

Buffaloman lost one horn during the fight with Warsman, he then donates the remaining so that Dr. Bombay could use it to help repair Kinikuman's arm. He regrows a set some time after.

They don't grow back. Warsman broke one, and he uses the other to save Meat's head but in the process is killed by the devil. When he's revived he has a new set, During the Dream tag arc, he loses one to Kendaman and Screwkid, than he donates his other horn for Kinnikuman. During his fight with Mammothman, Kinnikuman gives him a new set.

you obviously have not read the manga or watched the anime. His horns go through a lot of abuse... at some point he removes them completely so they can be made into an artificla bone to fix Kinnikumans broken arm.
