Bang

Bang also known as Silver Fang ( シルバーフエング, Shiruba Fuengu) is an S-Class, rank 3, superhero for the Heroes Association, settled in Z-City. Bang owns a dojo passed down from generations, and uses the fighting style the Rock-Smashing Water Stream Fist.

Appearance
Bang is an old man with white-spiky hair, thick eyebrows and a thick mustache. He has distinct wrinkles on his face, a squarish chin and has slightly tan skin. He wears a dark shirt, light colored pants and kung fu shoes.

Personality
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 many of the other heroes in the series, Bang also 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 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 Ryuusui Gansai Ken (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 Ryuusui Gansai Ken much to the disinterest of his guests.

Giant Meteor Arc
Bang is left with an impossible task by the Heroes Association, to stop a meteor of a Dragon-level disaster that is on a collision course towards Z-City. At the Heroes Association, he meets Genos to whom he explains the disaster. However, he claims that it is an impossible task and advises Genos to evacuate the city. When the siren signals warning everyone to evacuate, Genos wonders what Bang is going to do, to which Bang replies that he will protect his dojo. He turns around and asks Genos if he has ever heard of the Rock-Smashing Water Stream Fist fighting style, but to his surprise Genos has already left the building.

Bang later shows up when Genos is preparing to attack the meteor. He sees that Genos is freaking out and calms him down. Bang then watches as Genos attempts to and fails to destroy the meteor. Saitama then shows up and destroys the meteor and Bang uses his martial arts to destroy fragments of the meteor from hitting Genos and then carries him away when the building collapses.

Bang makes a small appearance standing on a roof watching Tanktop Tiger and Tanktop Black Hole as they attempt to break Saitama. He solemnly notes that Saitama, like all heroes, will have to bear this hatred even for their beneficial actions and take responsibility for it even when they do not deserve it and hopes that the hero industry will not break him on his road to become a hero. When the two Tanktop heroes declare a public challenge against Saitama, Bang notes that it is the common "newbie crushing" tactic but notes that due to their overwhelming desire in trying to defeat Saitama, they will be the ones defeated. He then leaves, noting that the problem has been solved.

S-Class Hero Arc
Bang is seen at his dojo demonstrating his technique for Saitama and Genos. When he asks the two whether they would like to attempt the technique, they refuse, causing Charanko to attempt to battle with Genos only to submit just as quickly. Upon inquiry as to the whereabouts of the rest of his students, Bang tells the story of his student, Garou, and of how he was forced to punish and expel Garou after the student lost control and attacked and defeated several of the other skilled members of Bang's dojo. Upon Saitama commenting on Bang's strength, Charanko is once again set into an uproar, this time over Saitama's ignorance of the legendary Silver Fang, and Bang reprimands his student for speaking out of turn to Saitama, whom Bang recognizes as several times stronger than himself. A messenger from the Heroes Association then arrives and informs Bang that all S-Class Heroes have been summoned to A-City HQ due to a major crisis.

Upon arrival at HQ, Bang, Saitama, and Genos encounter Atomic Samurai, who recognizes Bang and Genos but not Saitama. Greeting Atomic Samurai in turn, Bang informs him of who Saitama is and expresses great confidence in Saitama's strength, stating that Saitama will soon make it to the top of S-Class. Bang is next shown at his seat in the meeting, asking about the reason the S-Class heroes have been called.

Abilities
Being the third ranked S-Class hero, Bang is presumably very powerful. He has been shown to be able to destroy meteor fragments with his bare hands.

Rock-Smashing Water Stream Fist: Not much is known about Bang's martial arts, but it has been shown to be relatively powerful, destroying meteor fragments easily. He's able to create an area where his fists will destroy anything that enters, protecting those inside.
