Bang (バング, Bangu), also known by his hero alias Silver Fang (シルバーファング, Shirubā Fangu) is the S-Class Rank 3 hero for the Hero Association, settled in Z-City. Bang is also one of the few people that recognize Saitama's strength.


Bang has a serious personality, he acts calm and does not seem to be afraid at the prospect of stopping a dragon-level disaster meteor. Unlike most other heroes in the series, Bang prefers to be called by his name.

Bang is also well grounded in the ethics of a hero, he calls the other S-Class heroes heartless, the ones nearby for forgetting about the disaster in Z-City and the others for attending to their own problems instead. Additionally, when witnessing Tanktop Black Hole accuse Saitama of the civilians' misery, Bang watches from a distance sympathetically, but without interfering, noting that heroes will normally have to deal with the lack of appreciation for their actions and take responsibility. Later, when Charanko confronts Saitama with praise of the martial arts master's skill and hero rank, Bang angrily warns Charanko not to embarrass him, outright stating that Saitama is many times stronger than he is.

Perhaps due to losing all but one of his disciples to his former top disciple Garou, on top of his old age and his remaining disciple's incompetence, Bang also eagerly looks for new disciples to succeed him. After stating that he would not want the meteorite to fall on Z-City as it would erase his dojo, Bang quickly demonstrates his Water Stream Rock Smashing Fist, only to realize that Genos had already disappeared. Later, he invites Saitama and Genos to his dojo claiming to show them something interesting, only to demonstrate the Water Stream Rock Smashing Fist much to the disinterest of his guests.

Bang deeply cares for his former disciple, Garou. He fears for Garou's fate about becoming a monster, a process that seems irreversible.

When Bang is angry, he speaks less. In addition, when Bang is angry, his fighting style becomes very different. Instead valuing efficiency, his methods become very ruthless such as killing a monster with an endless barrage instead of a single powerful blow.


Bang owns a dojo passed down from generations, and uses the fighting style, the Water Stream Rock Smashing Fist, while his older brother named Bomb, is the master of the Whirlwind Iron Cutting Fist. Bang once participated in Super Fight tournament to promote his dojo and won. At some point, Bang had many students, his top student being Garou. One day, as Bang was away, Garou rampaged through the dojo, injuring many of Bang's students, including Sour Face. Because of his actions, Bang beat up Garou and expelled him and because of the rampage, Bang lost all of his students.
