After a nail-biting six-year hiatus, One Punch Man has roared back to life with Season 3, delivering the high-octane action, satirical superhero flair, and bald-headed brilliance fans have craved. Premiering just yesterday on October 12, 2025, the new season dives headfirst into the sprawling Monster Association arc, setting the stage for some of the series’ most epic confrontations. At the top of every viewer’s wishlist? The long-teased showdown between the unbeatable Saitama and his monstrous rival, Garou.
But when exactly will we see Saitama’s “Serious Punch” clash with Garou’s cosmic fury? Here’s everything we know so far.
Season 3 Release Details
One Punch Man Season 3 kicked off with Episode 1 on Sunday, October 12, 2025, marking the 10th anniversary of the anime’s original premiere. New episodes drop every Sunday at around 11:15 AM PT.
When Does Saitama vs. Garou Go Down?
Ah, the moment we’ve all been punch-drunk on. In the manga, the Saitama vs. Awakened Garou fight is a multi-chapter spectacle—cosmic stakes, planet-shaking blows, and Saitama finally breaking a sweat (sort of). It’s the arc’s emotional and action peak, redefining both characters.
Based on pacing (40–50 chapters per season), the core fight likely erupts mid-season, around Episodes 8–10 (November 23–December 7, 2025). It spans several episodes for maximum impact, potentially ending the season on a mind-blowing high note.
Fans on forums like Reddit speculate it might spill into a Season 4 if the arc overruns, but with 12 episodes locked in, expect the brawl to be the finale fireworks. Director Shinpei Nagai has teased “unprecedented scale,” so buckle up— this isn’t just a fight; it’s Saitama’s first real “worthy opponent” test.
