One Punch Man season 3 release date speculation, plot, trailer, news

Based on the 2009 manga and webcomic from Yusuke Murata, One Punch Man follows a hero named Saitama. Initially a hero just for fun, Saitama decides to sign up as a professional hero at the Hero Association once he realises that nobody knows who he is.

With that in mind, Saitama sets out to find an adversary worthy of his immense power.

One Punch Man has had two knockout seasons so far, airing in 2015 and 2019. With plenty of story left to tell from the source material, season 3 is bound to knock the socks off any fan eager to see what the next instalment will bring.

Read on to learn everything we know about One Punch Man season 3.

One Punch Man season 3 release date speculation

One Punch Man season 3 will be released in October 2025. We're still waiting on a specific release date, but considering it's been over five years since we last saw Saitama, the fact that the third season has a release window at all deserves to be celebrated.

One producer has also promised the season "won't disappoint" (via Anime Mojo).

Staff producer Atsushi Fujishiro said: "Preparations for the third season are steadily progressing. As a highly popular title with high expectations, we’re committed to delivering a season that won’t disappoint."

Luckily, One Punch Man fans are used to long waits - with the first season airing in 2016 and the second in 2019, they've definitely had to learn some patience!

It has been confirmed via a press release from Crunchyroll that season 3 will see the return of Tomohiro Suzuki as series composition and Chikashi Kubota, Ryōsuke Shirakawa and Shinjiro Kuroda as character designers.

As for music, Makoto Miyazaki will also make a return as music composer.

JCSTAFF and Crunchyroll have also released a brand new visual teaser for season 3, which you can view below.

What will the plot of One Punch Man season 3 be?

One Punch Man season 3 will continue the narrative events of the Monster Association arc. Fans of the manga will know that this is the arc that puts Saitama to the test in a unique way.

After a long three years of special training, Saitama has practically become invincible. But even he'll have to deal with strong enemies and deception in this arc, as the Monster Association attempts to trick the Hero Association by proposing that heroes and monsters co-exist and live together in harmony.

This turns out to be a ruse, with the monsters instead wanting all-out war. So, expect lots of intense action in One Punch Man season 3.

There's also a focus on Garou, who is confronted by heroes wanting to prove themselves to the Hero Association. Unluckily, he ends up embroiled in a fight with Saitama’s protege Genos - but luckily Saitama saves the day.

In terms of continuing chapters from the manga, we expect to pick up at Chapter 86.

One Punch Man season 3 cast: Who could return?

Naturally, Saitama and his protégé Genos will feature prominently in the next season of One Punch Man. Besides those two, we’re expecting all of our favourite One Punch Man characters to return.

On the heroic side, expect to see the likes of Atomic Samurai, Child Emperor, Metal Knight, and Zombieman, among many others, in the organisation’s upper echelons.

For monsters, besides the above, it’s up in the air because most are already dead, thanks to Saitama, but we know Garou and Orochi will both be a major focus.

Is there a trailer for One Punch Man season 3?

Yes! Check out the latest trailer, released in March 2025, below:

Who can survive Saitama's death punch?

Given he is the titular 'One Punch Man', there aren't many people who can take such a brutal beatdown from the world's greatest fighter - but there are a few.

One of these is Lord Boros, who was able to take a normal punch from Saitama that had the intent to kill him behind it - his true power was concealed by his armour, which entirely shattered upon Saitama's punch.

But even after that, he was able to take two more punches, a conservative normal punch and a serious punch, making him one of the only beings in the One Punch Man universe to not immediately crumple on contact.

There's also the likes of Overgrown Rover, but it's worth noting that it doesn't seem Saitama set out to kill them, just to teach him a lesson in manners. While he held back, it's clear that there was still some serious power packed into Saitama's punch, so even surviving that is a slight miracle.
