One-Punch Man
A hero for fun who wins in one hit.
Overview
Saitama is a hero so overpowered that no fight lasts more than a punch. ONE and Yusuke Murata's series is a satire of the power-fantasy shonen genre — its real drama is what happens to a man who solved his own premise on page one.
Every arc, explained
Saitama Introduction
Episodes S1 E1–3The premise is set: a bald man in a jumpsuit ends every fight instantly.
Hero Association
Episodes S1 E4–12The show introduces the ranked-hero bureaucracy and Genos as Saitama's disciple.
Monster Association
Episodes S2Garou, the Hero Hunter, becomes the counter-thesis to Saitama's boredom.
There isn't one in the traditional sense — that's the joke. Every other character has strict rules, ranks, and cybernetic upgrades; Saitama alone breaks the ceiling.
The Hero Association ranks its members S–C-Class and dispatches them against a global bestiary of monsters. Cities are named A through Z, and the destruction economy runs the plot as much as any villain.

Frequently asked questions
Is Season 2 worth watching?+
Yes, but expect a visible drop in animation quality from the Madhouse-produced first season.
Should I read the webcomic or the manga?+
Murata's manga is the polished version. ONE's webcomic is a rougher, faster draft of the same story.
Conclusion
One-Punch Man earned its spot in the AnimeVerse library because it did what most anime doesn't: it kept its promises. The arcs paid off. The characters grew. The world got bigger the longer we sat with it. If you're picking your next weekend of viewing, this is one worth clearing the calendar for.
