Bang, alias Silver Fang, is an 81-year-old human male holding Rank 3 among the S-Class heroes of the Hero Association. Renowned as one of the organization's most powerful heroes ever and a supreme martial arts master alongside his brother Bomb, he founded the Water Stream Rock Smashing Fist. This style flows like a calm stream to redirect foes before delivering rock-shattering strikes. In his youth, Bang developed the Exploding Heart Release Fist but sealed it away due to its destructive nature. He operated a dojo to teach his arts, though enrollment dwindled over time. His notable students include Genos and Garou; Bang expelled Garou after the latter's violent tendencies surfaced, an event profoundly impacting both. Despite his age, Bang possesses superhuman physical traits: massively hypersonic+ speed, city-level destructive capability and durability, and class M lifting strength. His stamina remains high but can be hindered by prolonged exertion due to age. Key techniques encompass Water Stream Encampment for area defense and attack reflection, Fang Interpolation for precise pressure point strikes, and Awakening Breath—a method temporarily amplifying his physical limits through maximal exertion. Bang participated in major conflicts, defeating the Dragon-level threat Melzargard during the Alien Conquerors arc by crushing its regenerative orbs. In the Monster Association arc, he and Bomb shattered Elder Centipede's carapace using the Roaring Aura Sky Ripping Fist. He later rescued Tanktop Master by kicking through Gums and effortlessly deflected airborne attacks from Fuhrer Ugly. With Bomb and Fubuki's support, he subdued Overgrown Rover using the Cross Fang Dragon Slayer Fist. His confrontations with Garou initially showcased his martial superiority. However, after Garou's transformations and mastery of the Exploding Heart Release Fist, their final battle during the Monster Association incident concluded with Bang unable to halt Garou's monsterization. This defeat and the battle's physical toll contributed to Bang retiring from active hero duties. His character reflects a disciplined martial philosophy emphasizing art over victory, though he acknowledged limitations in adopting new techniques due to age. Weaknesses include stamina constraints from aging and an unwillingness to learn new methods. Following the Monster Association incident, Bang retired, concluding his active heroism. His legacy endures through his techniques and students, cementing his status as a Hero Association pillar and a "Greatest Treasure of Martial Arts."
