"ONE PUNCHHHHHHHHH!"

Season 2 left off with Garou taking on a vast assortment of heroes and receiving a legendary beatdown from Bang and Bomb.

Who Is Saitama?

Saitama, AKA One Punch Man, is the leading protagonist of the hit anime show. He trained for his abilities solely by performing 100 pushups, 100 sit-ups, 10km run, and 100 squats...and gained the powers of a literal god...with a hilariously simple strength and conditioning routine. And, this gave him the power to defeat all monsters and foes with one punch.

What Is Season 3 Going To Be About?

The Monster Association Arc kicks off a large-scale conflict between heroes and an underground network of terrifying monsters (the Monster Association) threatening humanity’s survival. As tensions rise, the Hero Association mobilizes its strongest fighters, while alliances and rivalries begin to blur across both sides. 

We can expect catastrophic battles, new abilities, and moral questions about what truly makes someone a hero — or a monster. It’s one of the series’ most ambitious storylines yet, packed with high-stakes action and dark humor that makes us love One-Punch Man’s satirical world.
