One-Punch Man Season 3

The Hero Association’s war with the Monster Association is still raging, and peace on Earth remains fragile. Garou—the notorious hero hunter—has evaded capture, while the Monster Association’s abduction of an important figure throws the heroes into disarray. With time running out to mount a rescue, the Association mobilizes its fighters to track down the monsters’ hidden base.

Badly wounded, Garou is taken in by the Monster Association, which eyes him as a potential asset among its leadership. To rise through their ranks, he’s pushed to prove he can abandon his humanity by killing a hero—only to cross paths with the unbothered Saitama, who drops him with effortless ease. The fallout leaves Garou branded a traitor by the monsters just as the next major showdown between the two factions closes in, with both sides willing to use any means and any pawns to gain the upper hand.
