From One Punch Man

About Bang
Bang, the Silver Fang, is an elderly S-Class hero and master of the Water Stream Rock Smashing Fist dojo. Dignified, immensely strong and haunted by his star pupil Garou's fall, he joins the hero hunt against his own student with a heavy heart. Bang represents the old school of martial honour in a hero industry obsessed with rankings, and one of the few people who suspects Saitama's true level.
Appearance
Bang is a lean, weathered old man with spiky white hair, a thick moustache and a body that remains startlingly muscular under his simple training clothes. He moves with a martial artist's economy, no flourish, no waste, and his calm, appraising eyes miss very little. In battle his posture changes completely: the Water Stream Rock Smashing Fist turns his whole body into flowing deflections, an old man suddenly impossible to touch.
Personality
Bang is dignified, patient and quietly humorous, an elder statesman in a hero industry of influencers and rankings. He recognises real strength without needing it announced, he is one of the first S-Class heroes to suspect Saitama's true level, and he treats younger heroes with a master's encouragement. Garou is his open wound: pride in the boy's genius, guilt for failing him, and a settled determination to be the one who stops him, whatever it costs.
Background & Story
Bang, hero name Silver Fang, built his name as one of the world's great martial artists, founding a dojo for his Water Stream Rock Smashing Fist, a defensive style that redirects an opponent's force. His greatest failure is personal: his star pupil Garou, a prodigy he expelled for savagely beating fellow students, has returned as the self-declared human monster hunting heroes. Bang joins the hero hunt against Garou with his brother Bomb at his side, carrying a master's responsibility for what his student became, even as Garou's rampage draws the Monster Association war down on the whole hero world.
Powers & Abilities

- Master's Perception: Decades of combat give Bang instant reads on an opponent's strength and intentions, he gauges fighters more accurately than the Association's own systems.
Key Relationships
- Garou: His former top student and his greatest responsibility, Bang hunts the hero hunter as a master cleaning up his own failure.
- Saitama: A young hero whose strength Bang recognises early; he repeatedly tries to recruit Saitama (and Genos) to his dojo, to comic effect.
- Genos: Saitama's disciple, whom Bang treats as a fellow student of the hero path, the respectful disciple Garou never was.
- Atomic Samurai: A fellow veteran of the old school among the S-Class, with a shared impatience for the Association's fame culture.
