Optional Extras
5
One-Punch Man: Road to Hero
A single episode set in Saitama's early days as a weak hero, when he still had hair and relied on a local tailor to keep his clothes in one piece. Set before Season 1, but funnier once you know who he becomes.
⚠ Originally released only in Japan, bundled with a special edition of manga volume 10. It is the only entry with no English dub.
6
One-Punch Man OVA
Six short comedy side stories, about ten minutes each, released with the Season 1 home video volumes. Watch after Season 1.
7
One-Punch Man Season 2 OVA
Six more short side stories, released with the Season 2 home video volumes. Watch after Season 2.
Why This Order
One-Punch Man has no branching continuity. The three TV seasons run in a straight line, each picking up exactly where the previous one stopped, so the recommended order is simply Season 1, Season 2 and Season 3.
Everything else is optional. The two OVA sets are six short side stories each, roughly ten minutes an episode, that were released alongside the home video volumes of Season 1 and Season 2. They never affect the plot. Road to Hero is a single 24-minute episode showing Saitama in his early days as a weak hero, before the costume and before he lost his hair. It was bundled with a special edition of the tenth manga volume in Japan and is the only entry with no English dub.
Road to Hero is set before Season 1, but it works better after it. The episode leans on jokes about how different Saitama used to be, and those land only once you know who he becomes. That is why it sits in the extras here and at the top of the chronological tab.
Season 3 ends partway through the Monster Association arc, right after Saitama's fight with Orochi. The second half has been announced for 2027 with no month yet, so the story is currently on a long pause.

One Punch Man
Alternative Version Manga
The anime follows the manga remake by ONE and Yusuke Murata. Season 3 Part 1 stops right after Saitama's fight with Orochi, partway through the Monster Association arc. Guides place the restart point at chapter 115 or 117, so starting at chapter 115 is the safe choice. The manga is ongoing, with 37 volumes out in Japan as of July 2026, and Viz publishes it in English.
One-Punch Man Watch Order FAQ
What order should I watch One-Punch Man in?
Season 1, Season 2, then Season 3. The seasons run in a straight line with no alternate versions. The two OVA sets and the Road to Hero episode are optional side stories you can watch after the season they belong to.
How many episodes of One-Punch Man are there, and how long does it take to watch?
The three TV seasons total 36 episodes, about 14.5 hours. The two OVA sets add twelve short episodes of roughly ten minutes each, and Road to Hero adds one 24-minute episode.
Where does Road to Hero fit, and do I need it?
It is set before Season 1, in Saitama's early days as a weak hero, but it is optional and works best after Season 1, once you know who he becomes. It was released in Japan bundled with a special edition of manga volume 10 and has never been dubbed in English.
Can I skip the One-Punch Man OVAs?
Yes. Both OVA sets are short comedy side stories released with the home video volumes of Season 1 and Season 2. Nothing in them affects the main plot.
Why does Season 2 look so different from Season 1?
Season 1 was animated by Madhouse. Seasons 2 and 3 were made by a different studio, J.C.Staff, with a new director, so the look changed. The story itself continues directly from Season 1 without any gap.
What is the episode 0 recap before Season 3?
Get It All in One Punch! aired on October 5, 2025, a week before Season 3 began. It is a recap of Season 2 with no new story, so you can skip it if you have just finished Season 2.
Where does Season 3 end?
Season 3 Part 1 ends right after Saitama's fight with Orochi, partway through the Monster Association arc. The rest of the arc, including Saitama's confrontation with Garou, is still ahead.
When does One-Punch Man Season 3 Part 2 come out?
It was announced for 2027 right after Season 3's finale on December 28, 2025. No month has been announced yet. It continues from episode 37.
Where do I start the manga after the anime?
Pick up right after Saitama's fight with Orochi. Guides disagree by a couple of chapters on the exact number, placing it at chapter 115 or 117, so starting at chapter 115 guarantees you miss nothing. The manga is still ongoing, with 37 volumes out in Japan as of July 2026, and Viz publishes it in English.
Is the anime based on the webcomic or the manga?
Mainly on the manga remake drawn by Yusuke Murata, which is based on ONE's original webcomic but expands and reworks it considerably, especially in the Monster Association arc. If you want to continue after the anime, the Murata manga is the version that matches it.
Is One-Punch Man dubbed in English?
Yes. Seasons 1 and 2 have English dubs, and the Season 3 dub began streaming on November 30, 2025. The only entry without an English dub is Road to Hero.
Where can I watch One-Punch Man Season 3?
At the time of writing, Season 3 streams on Hulu in the US, Disney+ in Canada, Crunchyroll in the UK and Europe, and Netflix or Crunchyroll in Australia and New Zealand. It is not on Crunchyroll in the US. Streaming rights change, so check your local service.
