1. Introduction to One Punch Man Season 2
One Punch Man Season 2 focuses less on Saitama’s unbeatable strength and more on world-building, moral conflict, and character development. The season introduces one of the most important characters in the series — Garou, whose ideology challenges the hero system itself.
2. Recap of Season 1
Season 1 established:
- Saitama’s limitless power
- The Hero Association
- The idea that heroes are ranked by popularity, not strength
Despite saving the world repeatedly, Saitama remains largely unrecognized.
3. Hero Association & Rankings Explained
Heroes are divided into four classes:
- Class C
- Class B
- Class A
- Class S (Strongest)
Season 2 highlights the flaws in this system, where image and reputation often matter more than real heroism.
4. Garou: The Hero Hunter
Garou, a former disciple of Silver Fang (Bang), becomes the main antagonist of Season 2.
Garou believes:

His goal is to become the ultimate monster.
