Buffaloman is a charging bull-themed Choujin and one of the Seven Akuma Choujin who were said to be too strong and brutal and banished to the ends of the universe. He is very large and has two curved horns called Long Horns (ロングホーン) on both sides of his head. His techniques and fighting style usually rely on his immense strength and power, but in tight situations he can lower his power in order to become faster. Additionally, he specializes in brutal fighting and has a spike on each knee. On the other side though, he is quite clever and will often lure his opponents into wasting stamina.

Depicted as a formidable opponent far more powerful than any other Choujin to appear before him, the concept of Choujin Kyoudo was introduced specifically to illustrate this. Buffaloman's Choujin Kyoudo is 10,000,000 Power, which is 10 times that of Warsman, Kinnikuman's greatest opponent before him. By the end of the series many Choujin who surpass 10,000,000 Power have appeared, but Buffaloman still boasts of his power and it is the only one treated as an advantage.

Though an Akuma Choujin, he normally fights very honorably and shows his opponents respect. During his fight with Kinnikuman his good heart is awakened, and he is revived as a Seigi Choujin after his first death.

The buffalo in his name more than likely comes from the water buffalo, as his Long Horns resemble theirs. Also, his hailing from Spain and his habit of charging forward with his Long Horns in front implies he may be inspired by bullfighting as well.

Yudetamago have stated that Buffaloman is modeled after professional wrestler Bruiser Brody. In tribute to the larger Brody's tag team collaboration with the smaller Jimmy Snuka, Buffaloman is paired in tag matches with smaller characters like Springman and Mongolman.
