🥊One-Punch Man Season 3 (2025) – Saitama Returns with Earth-Shaking Battles: Cast, Plot, Release Date & Where to Watch

"100 push-ups, 100 sit-ups, 100 squats, and a 10km run… every single day!" – The legend of Saitama continues as the long-awaited One-Punch Man Season 3 finally arrives this October 5, 2025. Streaming on Hulu in the United States and Crunchyroll in Europe and the Middle East, this season promises to be the most explosive yet—delivering galactic-scale battles, shocking betrayals, and a new era of heroes and monsters.

📖 The Story So Far

On a world ravaged by monsters, only the Hero Association stands between humanity and annihilation. Yet among its countless ranked heroes, one man stands above them all: Saitama, the bald-headed hero from City Z who can defeat any opponent with a single punch.

But such absolute power is a curse. No matter how powerful his enemies—whether the alien conqueror Boros or the monstrous Deep Sea King—Saitama’s battles end in seconds, leaving him disillusioned and yearning for a worthy opponent.

Now, with the rise of the Hero Hunter Garo and the sinister Monster Association, the balance of power is shifting. Dark forces move in the shadows, and a cosmic entity known only as God whispers promises of ultimate strength.

"If heroes are fakes… then I’ll be the monster who brings them down." – Garo

⚔️ What to Expect in Season 3

Season 3 will plunge us into the Monster Association Arc, one of the most ambitious and action-packed storylines from Yusuke Murata’s manga. Expect devastating showdowns, heart-wrenching sacrifices, and the long-awaited clash between Saitama and Garo—a battle that transcends time itself.

Key highlights include:

• 🔥 The Monster Association’s Rise – A dark new order emerges, with humans willingly transforming into monsters.

• ⚡ The Hero Hunter’s Evolution – Garo embraces monstrous power, threatening the very fabric of hero society.

• 🌌 Saitama vs. Garo – A cosmic duel that will push the story beyond Earth’s limits.

• 🛡️ The Neo Heroes – A new faction challenges the Hero Association, claiming to bring justice—but hiding dangerous secrets.

This season isn’t just about punches—it’s about morality, identity, and what it truly means to be a hero.
