It’s finally happening. After years of waiting, One Punch Man Season 3 is finally on its way. The anime premieres in Japan on October 5, 2025, with Hulu streaming it internationally from October 12, 2025.
And here’s the kicker: the release lines up with the 10th anniversary of the anime’s debut. Ten years since Saitama first nonchalantly punched his way into anime history, and now he’s back for the Monster Association Arc, one of the manga’s most legendary storylines. Get ready for:
- S-Class heroes stepping into the spotlight.
- Garou’s transformation into one of the most hyped anti-heroes in anime.
- Villains swarming on a terrifying scale.
- And of course, Saitama casually ending battles in one hit while wondering what to eat for dinner.
Sounds epic, right? But hold on… there’s a storm brewing in the fandom.
Fans Are Excited… But Nervous
Let’s be real this time: Season 2 still leaves a bad taste for some fans. When Madhouse handled Season 1, the fights looked like movie-level animation which hyped fans. Season 2, made by J.C. Staff, didn’t quite hit the same bar. The story was solid, but the fights? A bit stiff.
Now Season 3 is also with J.C. Staff. And the first teaser? Mostly still frames, barely any action. Fans on X (Twitter) instantly fired back with concerns: “Not again.” “Don’t ruin the Monster Association Arc!”
So yeah, the hype is real… but so are the nerves.
New Director, New Approach
This time, Shinpei Nagai takes the director’s chair. His background is mostly in slice-of-life anime, which raised eyebrows. Can he really handle the chaos of the Monster Association Arc?
Here’s the good news: Nagai confirmed Season 3’s production is already finished. That means no delays or sloppy, half-baked episodes. The team also experimented with a blend of 2D and 3D animation to keep fights consistent.
And the best part? Veteran animator Takashi Hashimoto (known for Bleach: Thousand-Year Blood War and My Hero Academia) is on the team. That’s the kind of name that reassures fans who want crisp, high-energy fight scenes.
Why You Should Still Be Hyped For One Punch Man Season 3
Will One Punch Man Season 3 look as good as Madhouse’s legendary first season? Well, Probably not. Even the director admits that.
But here’s the thing: the Monster Association Arc is so good that it almost doesn’t matter. It’s packed with crazy battles, shocking twists, and character growth. Garou’s arc alone is worth tuning in for, his evolution will blow casual viewers away, like what did even happen to him?
Add in fan-favorite heroes like Tatsumaki and Bang finally going all-out, and you’ve got a season that still has the potential to shine among anime fans.
At the end of the day, Saitama’s back. Whether you’re hyped for the fights, the characters, or just the memes, October 2025 is shaping up to be massive for anime fans.
