Bang/Relationships

Saitama
Saitama met Bang when the giant meteor was heading towards Z-City. Bang was amazed by Saitama's strength and tried numerous times to recruit him into his dojo, but Saitama always turns him down. Bang will occasionally invite him to cookouts and vice versa. Bang recognizes and respects Saitama's strength, telling Atomic Samurai that there is an upcoming hero (referring to Saitama) far stronger than the swordsman's disciples and even surpassing the martial artist himself.

Genos
The two get along fairly well. Bang passes advice onto Genos whenever he needs it and Genos holds a certain amount of respect towards Bang due to his martial arts skills and rank in the hero association. Like with Saitama, Bang tried to recruit Genos for his dojo but is turned down, and this constant attempt of recruitment has caused Genos to lash out at him on occasion. Bang often worries about Genos' recklessness, lamenting on the fact that Genos is still young and faces monsters that are usually much more powerful than the cyborg.

Superalloy Darkshine
Bang and Darkshine share mutual respect towards each other.

Tatsumaki
Bang respects Tatsumaki, but is often irritated by her immaturity and her violent tendencies. Tatsumaki acknowledges Bang's presence despite outranking him as she stood down when Bang told her to after the Dark Matter Thieves' invasion.

Despite this, Bang also acknowledges Tatsumaki's abilities, calling her the "leader" during the Monster Association raid.

Kamikaze
Out of every hero in the Hero Association, Atomic Samurai only acknowledges and holds a deep respect for Bang. He once stated to Saitama that he only acknowledges the strong, which could be a reason for Atomic Samurai's respect to Bang, who is one rank above Atomic Samurai. His relationship with Bang is friendly, with a tad bit of rivalry between them, though this mild rivalry appears to be one-sided as Bang doesn't view Atomic Samurai as a rival. He also displayed concern for Bang when he was struck by Melzargard. Both heroes would go out fishing together and have a talk about how despite that they've aged, they're still sharper and stronger as ever.

Garou
His former teacher Bang taught Garou everything he knows about fighting. After Garou went on a rampage and attacked his fellow students Bang kicked him out of his dojo. After he heard Garou started hero hunting Bang recruited his brother and went out to stop Garou.

Garou does not respect Bang as a person, but he admires Bang's martial arts, even copying a combined technique of Bang and Bomb as his own. Despite the villainous acts he has committed, Bang ultimately still cares for Garou. Garou recognizes Bang's lingering affection for his former student from how different his punches were when he was expelled. It is unknown what Garou now thinks.

Bomb
Bomb is Bang's older brother.
