Why this order?
One Punch Man is refreshingly simple to watch. The anime adapts the manga as one continuous story, so there is no branching timeline, no spin-off you need to slot in, and no debate about release versus chronological order. You watch Season 1, then Season 2, then Season 3. That single path is the "Watch order" toggle below and it covers every entry on this page.
Season 1 (2015) is the one everyone remembers: bald, bored superhero Saitama can end any fight with a single punch, and the show mines that premise for both comedy and gorgeous action, climaxing in the legendary battle against Lord Boros. Season 2 (2019) introduces the martial artist Garou and the Monster Association, and Season 3 (2025) continues that Monster Association arc directly. One thing to know going in: Season 3 is a split-cours season. Part 1 (12 episodes) aired October through December 2025, and Part 2 is scheduled for 2027, so the season is not yet complete. Because the plot runs straight through, watching out of order spoils major reveals and reduces the emotional payoff of Saitama's quiet search for a real challenge.
The one gotcha worth knowing is production, not plot. Season 1 was animated by Madhouse and is widely praised for its fluid fight scenes. Starting with Season 2, the studio changed to J.C.Staff, which also handled Season 3. The story carries over cleanly, but the animation style shifts, so do not be surprised that the later seasons look different from the first. There is also a short prequel OVA, "Road to Hero," set before Saitama becomes a hero; it is optional bonus material and not required to follow the main story.
If you enjoy this blend of overpowered protagonists and superhero satire, the same creator, ONE, also made Mob Psycho 100, another series worth lining up next.

Frequently asked questions
What order should I watch One Punch Man in?
Watch it by season in release order: Season 1 (2015), Season 2 (2019), then Season 3 (2025). It is one continuous story, so no other order makes sense. The optional 'Road to Hero' OVA is a prequel you can watch any time.
How many seasons and episodes of One Punch Man are there?
There are three seasons. Season 1 has 12 episodes and Season 2 has 12 episodes. Season 3 is split-cours: Part 1, which aired in 2025, has 12 episodes, while Part 2 is scheduled for 2027 and its episode count has not yet been announced. So 36 episodes have aired so far across the three seasons, with more to come when Season 3 Part 2 arrives, plus extra OVAs and specials like 'Road to Hero.'
Why does Season 2 look different from Season 1?
The animation studio changed. Madhouse produced the acclaimed Season 1, while J.C.Staff took over for Season 2 and Season 3. The story is unaffected, but the visual style noticeably shifts.
Do I need to watch the Road to Hero OVA?
No. 'Road to Hero' is an optional prequel OVA set before Saitama becomes a hero, originally bundled with the manga. It is fun bonus material but not required to follow the main plot.
Should I read the manga or webcomic first?
Not necessary. The anime adapts the story well on its own. Some fans read the ONE/Murata manga to get ahead of Season 3's arc, but you can enjoy the anime without any prior reading.
Is One Punch Man connected to Mob Psycho 100?
They share a creator, ONE, but the stories are unrelated. If you like One Punch Man's humor and overpowered hero, Mob Psycho 100 is a great series to watch next.
