Baki Hanma, a Japanese martial artist, is consumed by the quest to surpass his father, Yuujirou Hanma—the undisputed strongest creature on Earth—driven by a vengeful resolve to avenge his mother, Emi Akezawa, murdered by Yuujirou. His path began with rigorous childhood training financed by Emi, granting elite mentors and resources that forged him into a prodigious combatant. By 13, he gained infamy for dismantling local gangs, and by 15, claimed the championship of Tokyo’s lawless Underground Arena.
Standing 167–168 cm (5'6") with a scarred, muscular frame weighing 71–76 kg (156–168 lbs), Baki’s physique mirrors his relentless discipline. His appearance shifts from spiky orange hair in youth to darker, longer locks in adolescence, marked by a distinctive mole above his lip. His combat style fuses Mixed Martial Arts with ruthless adaptability: exploiting vulnerabilities, weaponizing blood to disorient foes, and pre-fight mental simulations to dismantle opponents psychologically.
Baki balances casual charisma with razor-sharp focus, shunning unnecessary brutality against weaker adversaries but taunting stronger rivals to provoke their full might. Loyalty defines his bonds, particularly toward girlfriend Kozue Matsumoto, whom he shields fiercely. Though fueled by hatred for Yuujirou, their dynamic oscillates between collaboration and grudging mutual respect, revealing layers of complexity.
Pivotal milestones include triumph in the Maximum Tournament, defeating titans like Jack Hanma and Kaiou Retsu to cement his legend. Subsequent trials pit him against escaped convicts, ancient warriors like Pickle, and the Chinese Raitai Tournament’s elite. These ordeals hone abilities such as endorphin-fueled reflexes and the "Demon Back," a temporary surge of primal power from his Hanma lineage.
His relentless pursuit leads to audacious feats, including storming Arizona State Prison to battle Biscuit Oliva, showcasing tactical brilliance and unyielding endurance. Baki’s journey peaks in a cataclysmic clash with Yuujirou, earning him the title "strongest boy on Earth," yet his hunger to transcend limits persists.
Interweaving raw power with cerebral strategy, Baki embodies a fusion of innate lineage and self-forged mastery. His saga, etched in perpetual growth, navigates the shadows of familial legacy while carving a path toward redemption through unending combat.
