Description
Buffaloman, a bull-themed Choujin originating from Spain, was initially a member of the banished Seven Devil Choujin due to excessive brutality. His early training within a hurricane led to the creation of the Choujin Cross Drop technique after halting a flying church cross. Desperate for greater power, he forged a pact with Satan, gaining 10,000,000 Choujin Power—ten times greater than previous top fighters—by murdering other Choujin; each kill amplified his strength and shrouded him in evil energy.

As the de facto leader of the Seven Devil Choujin, Buffaloman instigated conflict by dismembering Meat Alexandria, forcing Kinnikuman into a ten-day tournament to reclaim the parts. He brutally killed Warsman during this arc, utilizing his Hurricane Mixer. His subsequent match against Kinnikuman in the Denen Colosseum triggered a transformation. Possessed by Satan mid-fight, Buffaloman's honor was awakened by Kinnikuman's fair treatment. He sacrificed his final horn to save Meat and relinquished his accumulated power to resurrect fallen Justice Choujin, resulting in his death as Satan's punishment.

Resurrected later, Buffaloman defected to the Justice Choujin faction, participating in tournaments like the Golden Mask arc. He maintained complex loyalties, briefly rejoining the Devil Choujin during the Scramble for the Throne arc out of duty while still respecting his Justice allies. His patriotism for Spain surfaced when he confronted Psychoman for destroying the Sagrada Família monument.

Significant bonds formed, particularly with Springman; they tag-teamed multiple times until Springman's death during a fight against Turboman and Grim Reaper deeply affected Buffaloman. He also partnered with Mongolman as the "20 Million Powers" tag team and revered his mentor, Sneagator. In later years, he retired from active combat to teach the New Generation Choujin.

Physically, Buffaloman stood exceptionally tall at 250 cm, heavily muscular, with curly dark hair, pure white eyes, and horns called Long Horns. His minimal attire typically consisted of black shorts, arm and leg guards, red gloves and boots, and knee spikes. Satan's possession turned his skin purple, marked by a fiery facial symbol.

His fighting style merged brute strength with tactical cunning, often luring opponents into stamina-draining traps. Key techniques included the Long Horn Boomerang, Buffalo Bomb, and Choujin Cross Slam. He could lower his power to increase speed. Video game adaptations depict him as a slow, high-damage grappler with strong defense and throw-based moves.

In the *Perfect Origin Arc*, Buffaloman reappeared as a Devil Choujin defender against the Perfect Large Numbers invasion. He volunteered to fight Strong the Budo to spare his comrade The Mountain, later witnessing The Mountain's sacrificial death and honoring his resolve. Buffaloman also protected Spain from invading forces, reaffirming his national loyalty.

Across official media, Buffaloman ranked highly in popularity polls, achieving third place in the series' second character election.
