Garou

Garou is a martial artist and major antagonist-turned-antihero in One-Punch Man. A former student of Bang, he declares himself a Hero Hunter and attacks professional heroes to challenge the moral categories of hero and monster.

Garou as the Hero Hunter

Defiant, analytical, and sympathetic toward social outcasts, Garou wants to become an absolute evil that unites everyone against him. His brutality is limited by a persistent refusal to kill vulnerable people.

Martial adaptation, monsterization, and the failed ideal of absolute evil

Garou masters Water Stream Rock Smashing Fist, copies techniques, adapts rapidly, and undergoes increasingly monstrous transformations. His encounters with Bang, Tareo, and Saitama expose the contradiction between his claimed villainy and instinct to protect the weak.
