One Punch Man

On a supercontinent Earth, powerful monsters and villains wreak havoc in the cities. In response, the millionaire Agoni creates the Hero Association, which employs superheroes to fight evil.
Saitama, an unassociated hero, hails from City Z and performs heroic deeds as a hobby.
He has trained himself to the point of being able to defeat any enemy with a single punch, but his unmatched strength has left him with an overwhelming sense of boredom. Saitama becomes a reluctant mentor to Genos, a cyborg seeking revenge against another cyborg who killed his family and destroyed his hometown, after saving him from a monster.
Saitama and Genos join the Hero Association in hopes of attaining notability, but due to scoring low on the written entry exam, Saitama is placed at a low-entry rank, and his feats remain unnoticed by the public despite saving people from two colossal disasters even after registration.
