Garou, dubbed the "Hero Hunter," trained under martial arts master Bang until violent tendencies caused his expulsion. Childhood bullying and ostracization shaped his worldview, culminating in an incident where a peer, Tacchan, forced him into a "monster" role during a game, leading to unjust punishment. Media narratives of monsters’ inevitable defeats solidified his resolve to become the ultimate monster and颠覆 societal perceptions of heroism. Initially targeting heroes to dismantle a system he deemed corrupt—prioritizing popularity over justice—Garou adhered to an unspoken code, refusing to kill heroes or harm civilians. His accidental protection of the child Tareo, whom he repeatedly rescued, exposed his lingering humanity. Tareo’s presence became a grounding force, highlighting Garou’s internal conflict between monstrous ambitions and latent morality. Garou’s evolution began as a martial artist mastering Bang’s Water Stream Rock Smashing Fist, achieving superhuman prowess. Through brutal combat, he underwent monsterization: Frenzied, Half-Monster, and Spiral forms enhanced his strength and adaptability. As "Monster Garou," he overwhelmed elite heroes and monsters, adopting a feral, armor-clad form. After encountering the cosmic entity "God," he attained Cosmic Fear Mode, wielding energy manipulation and radiation emission. This power corrupted him, unintentionally poisoning Tareo—a consequence that haunted him. During a climactic battle with Saitama, Garou briefly matched his godlike strength before confronting his ideology’s futility. Witnessing Tareo’s near-fatal radiation exposure, he harnessed time-travel to undo the destruction, sacrificing his powers and reverting to humanity. Post-defeat, he fled, his future unresolved yet hinting at potential redemption. Supplemental media expanded his persona: an OVA depicted him in a virtual tournament, emphasizing his competitive ruthlessness, while manga chapters showcased early encounters where he defiantly embraced his self-proclaimed role as society’s "Villain." Garou’s arc straddles villainy and reluctant heroism, driven by a crusade against systemic hypocrisy. His journey explores identity, moral ambiguity, and power’s duality, framing him as a complex figure who blurs the lines between hero and monster.
