One-Punch Man Episode 7: The Ultimate Disciple

Scientists and astronomers detect a massive meteorite changing course toward City Z, triggering citywide evacuation alerts and a call to all S-Class heroes. At home, Saitama and Genos discuss their latest hero rankings—Saitama steady in C-Class at 388th (now 345th) despite growing popularity, while Genos has climbed significantly—when Genos receives the Hero Association summons and heads out.

Genos arrives at the City Z Hero Association branch, where he's the only responder besides the elderly S-Class hero **Bang**, known as Silver Fang, who explains the **Dragon-level threat**: the meteor will obliterate City Z and damage neighboring cities upon impact. Bang urges evacuation to protect lives but stays himself due to his family dojo in the city; Genos leaves to act despite the odds.

Leaping across rooftops, Genos sees despairing civilians huddling in helplessness and realizes evacuation is impossible as the meteor's destruction would extend too far; he resolves to stop it himself, noting his teacher Saitama also lives in the city. Equipping prototype advanced metal cannon arms, Genos prepares his incineration cannon but hesitates, weighing the risk of shattering the meteor into deadly fragments versus total annihilation if he does nothing.

A remote-controlled drone from S-Class hero **Metal Knight** (Bofoi) arrives, not to help but to test weapons; it unleashes powerful missiles that leave the meteor unscathed. Bang reappears, advising Genos to "muddle through" without overthinking, clearing his doubts; Genos unleashes a full-power incineration blast, but it fails to damage the meteor and drains his energy completely, leaving him resigned to death as impact nears.

Saitama suddenly arrives, asks Bang to watch Genos, then leaps skyward and delivers a single **Serious Punch** that obliterates the meteor into fragments; the debris rains down, devastating buildings across City Z but averting total destruction with no reported casualties.

The next day, survivors amid the rubble blame Saitama for the damage. **Tanktop Tiger**'s brother, **Tanktop Black Hole**, rallies a crowd against him, accusing him of worsening the destruction; Tanktop Tiger attacks Saitama, who effortlessly crushes his fist. Black Hole confesses his lies and begs for mercy, but Saitama, confused yet uncrushed, addresses the mob: he's a hero because he wants to be, not for admiration, and scatters them with his presence.

Genos's ranking surges past 300th to 5th for his efforts, shocking Saitama.
