One Punch Man Season 3 Premieres After Six Years—Monster Association Arc Unleashed!

Anime fans, assemble! After a whopping six-year wait, One Punch Man Season 3 has finally landed — and yes, Saitama’s bald head is shinier than ever. The world’s most overpowered hero is back in action, and it’s safe to say that the anime community is losing its collective mind. From explosive trailers and studio shake-ups to an arc fans have been begging to see animated for years — this isn’t just a new season. It’s a moment.

Six Years Later, the Punch Has Landed

For those who may have blinked (and missed a decade of Saitama’s training), Season 2 wrapped up back in 2019. And fans? Well, they’ve been waiting patiently ever since. Now, on October 12, 2025, One Punch Man Season 3 officially premiered following a recap special on October 5. And the hype is real. This new season covers the Monster Association Arc — arguably the most epic, brutal, and emotionally loaded storyline in the manga. We’re talking massive monster fights, philosophical power struggles, and Garou’s descent into madness. Think of it as One Punch Man cranked up to 11.

Studio J.C. Staff Is Back — With a Stellar Creative Team

The animation studio returning for Season 3 is J.C. Staff, the same team behind Season 2’s production. While the Season 1 anime was produced by the legendary Madhouse — which set a high bar with fluid, jaw-dropping animation — J.C. Staff has been tasked with keeping the momentum alive amid some fan skepticism.

Here’s a quick rundown of the all-star creative crew behind this season:

♥ Series Composition: Tomohiro Suzuki, who shapes the overall storyline and pacing.

♥ Character Designers: Chikashi Kubota, Shinjiro Kuroda, and Ryosuke Shirakawa — three talented artists bringing Saitama, Garou, and the whole cast to life with fresh yet familiar vibes.

♥ Music Composer: Makoto Miyazaki, delivering the soundtrack that sets the emotional tone and adrenaline highs.

On the voice acting front, the heroes you love are returning to their roles:

♥ Makoto Furukawa reprises his role as Saitama, the hero bored out of his mind by his own invincibility.

♥ Hikaru Midorikawa returns as Garou, the complex anti-hero and “Hero Hunter” with a magnetizing presence.

♥ New to this season is Daisuke Nakamura, who will voice the enigmatic Dr. Genus, adding another layer of intrigue to the Monster Association arc.

Music to Get Punched To

If you thought the soundtrack would be tame, think again. Season 3 brings the HEAT with a brand-new opening theme — “Get No Satisfaction!” — by none other thanJAM Project ft. BABYMETAL. It’s loud, chaotic, and gloriously unhinged. Basically, everything One Punch Man should be.

The ending theme is performed by Makoto Furukawa himself (Saitama’s voice actor), giving fans an emotional cooldown after the high-octane episodes.

Plot & What to Expect

Season 3 will adapt the Monster Association Arc, one of the most action‑packed and intense arcs in the manga.

Episode 1, titled “Strategy Meeting,” sets the stage: a child of a Hero Association official has been kidnapped, prompting a rescue mission. Garou awakens deep underground, setting up conflict. We also expect themes of internal friction within the Hero Association, the shape of the war between heroes and monsters, and moral ambiguity especially around Garou’s transformation. New and returning characters (heroes, monsters) will appear, and fans hope many of the big fights from the manga will make it to the screen.

Conclusion:

After a long and eager wait, One Punch Man Season 3 has finally arrived to shake up the anime world once again. With the Monster Association Arc now unfolding on screen, fans are witnessing a deeper, darker side of this seemingly unstoppable universe. The battles are fierce, the stakes are higher, and the characters more complex than ever before. While the animation may spark debate, the storytelling, voice acting, and fresh musical energy bring the season to life in unforgettable ways. It’s a reminder that One Punch Man isn’t just about the punches — it’s about what lies beneath them: the struggles, the motivations, and the humanity of heroes and villains alike.
