One-Punch Man's Anime Collapsed — But the Manga Didn't
TL;DR: One-Punch Man Season 3 Part 1 (2025) shipped with embarrassing animation errors that turned fans into critics overnight. The manga by Yusuke Murata remains excellent. Season 3 Part 2 arrives in 2027. Here's what actually happened, where to watch, and why the franchise still has a pulse.
One-Punch Man Season 3 has a Garou Slide problem. And a floating-door problem. And a six-fingered athlete problem.
These aren't small nitpicks. They're production errors so visible that fans turned them into memes within hours of the episodes airing. After six years waiting for a new season, and with Madhouse's Season 1 still standing as a benchmark for anime action sequences, J.C.Staff delivered something that made longtime fans question whether anyone actually reviewed the footage before it shipped.
Here's what happened, and why it matters more than it looks.
Season 3 Part 1: Animation Errors That Became Memes
J.C.Staff took over production from Madhouse after Season 2, which itself landed below critical expectations (Season 1 had built a 90-point consensus; Season 2 didn't match it). The 2025 premiere of Season 3 Part 1 was supposed to be the recovery moment. It wasn't.
The problems are specific enough that you can point to them:
- The Garou Slide — a movement sequence so stiff and oddly timed it became instant Reddit fodder
- Mizuki's hands — extra fingers appearing between frames (just extra fingers, no story reason)
- Zombieman's door — the character appears to open a door using telekinesis, except it's not a character ability, just an animation mistake
- Atomic Samurai's hair — adapted so literally from the manga panel that it cuts off mid-frame, leaving him with an accidentally cropped haircut
- Genos's movement — visually flatter than Madhouse's version, stiff throughout
These aren't isolated frames buried in Episode 7. They're distributed across multiple episodes, enough that communities have assembled highlight reels. Movie OTT's streaming tracker has current availability if you want to see them yourself — though honestly, you'll spot them immediately.
What strikes me is the contrast with what happened on the manga side.
The Manga Artist Who Refused to Compromise
Yusuke Murata, illustrating the One-Punch Man manga adaptation, has been vocal about his creative process even when it frustrates readers. When fans pushed back on his constant redraws and chapter overhauls, Murata's response was blunt: "I'm not going to change myself." He meant it. He spent roughly eighteen months redrawing chapters related to the Empty Void arc and Neo Heroes introduction — essentially pausing the mainline story to meet his own standard.
Fans were frustrated by the delays. But the redraws produced artwork so detailed that it functions as a frame-by-frame blueprint for animation. Which makes the anime's errors even more puzzling. The source material is there. The reference is there. The studio shipped episodes with six-fingered characters anyway.
The thing nobody mentions: this is a resource problem, not a talent problem. J.C.Staff isn't incompetent. Toradora, A Certain Magical Index, DanMachi Season 4 — these are competent productions. One-Punch Man got under-resourced from the start, likely because the studio committed to too many simultaneous projects. Whether they can give Season 3 Part 2 the attention it needs while managing three other productions in 2027 is a legitimate question.
Where to Watch, and What You're Actually Getting Into
Original platform: Crunchyroll carries all three seasons globally. Specific regional availability shifts — Movie OTT tracks current listings across platforms, especially useful for Indian viewers checking Sony LIV and local Crunchyroll availability.
Release dates:
- Season 1: October 5, 2015 (Madhouse)
- Season 2: 2019 (J.C.Staff)
- Season 3 Part 1: 2025 (J.C.Staff)
- Season 3 Part 2: 2027 (J.C.Staff)
Voice cast (unchanged): Makoto Furukawa voices Saitama; Kaito Ishikawa voices Genos. Both are established voice actors with extensive credits. Neither is the problem here.
How to watch it: Start with Season 1 if you're new. It holds up. Then decide whether you want to continue — Part 2 doesn't arrive for two more years, so there's no rush.
What Happened to the Anime's Reputation
One-Punch Man Season 1 was a crossover hit. It brought non-anime viewers into the medium. Crunchyroll built marketing campaigns around properties like this. When something this visible stumbles, it doesn't just hurt the show — it affects how casual viewers perceive anime production overall.
Most coverage frames this collapse as a studio quality-control failure. The more uncomfortable read is that One-Punch Man's anime was never going to survive the transition from Madhouse, because Shingo Natsume's direction on Season 1 was a one-time alignment of freelance talent (Yutaka Nakamura, Kenichi Kutsuna, among others) that no standard TV production pipeline can replicate on schedule and budget. J.C.Staff didn't lose the magic. The magic was never transferable.
The comparison that keeps coming up is Berserk. Kentaro Miura's manga is a masterwork. The 1997 anime adaptation is respected. The 2016 and 2017 CGI-heavy adaptations became cautionary tales about what happens when adaptation quality collapses. The manga survived. The franchise's reputation took years to recover with new audiences.
One-Punch Man is tracking the same path. Season 1 set a benchmark. Seasons 2 and 3 retreated from it. The question isn't whether the manga is good — it clearly is. It's whether the anime still functions as an entry point for new fans, or whether it's now actively steering them away.
The Manga Is Building Toward Something Real
While the anime was generating memes, the manga was quietly advancing the story. The Neo Heroes Saga is now moving. This rival organization — competing with the Hero Association, leadership clearly nefarious — is finally showing its hand. Superalloy Darkshine is having an identity crisis. Suiko, sister of fan-favorite Suiryu, is getting meaningful page time. Even Child Emperor has resurfaced with a subplot that's genuinely funny.
And Saitama? He's barely the main character right now. That's not a flaw. One-Punch Man works best when it uses Saitama's absence to let the supporting cast breathe — the Monster Association Arc succeeded partly because Saitama stayed out of the central fight for so long. The manga is doing that again, and it's working.
Murata's artwork during the Cosmic Fear Garou sequence, which anime fans are presumably hoping Part 2 will cover, was some of the best sequential art published in manga in years. The double-page spread of Saitama and Garou punching through a starfield (Chapter 167 on Manga Plus) pulled over 9 million views on the platform within its first week, making it one of the most-read individual chapters Shueisha has tracked. Whether J.C.Staff can match those pages is an open question. Hard to say if even a competent production could pull it off.
For Indian readers following the manga: Viz Media's Shonen Jump app and Manga Plus by Shueisha both work in India. Manga Plus remains the most accessible legal free option.
Season 3 Part 2: What Needs to Happen, and When
Part 2 is scheduled for 2027. That's a two-year gap between parts — enough time to correct course, if the studio actually uses it. The chapters Part 2 will likely cover include the climax of the Monster Association Arc, specifically the Cosmic Fear Garou fight. These are the sequences fans most want to see animated. They're also the sequences where weak production becomes most visible. No hiding in a fight that Murata spent years drawing.
Trailer footage should surface in late 2026. Watch the key animation previews closely. If the Garou fight footage looks like Part 1, that's your answer. The franchise is stuck. If it looks like Season 1, the show might have a genuine second chance.

The Franchise Still Has Time to Recover
Here's what matters: the manga isn't going anywhere. Murata's refusal to compromise on quality means future readers will have excellent source material. The voice cast is locked in and solid. The core story remains strong.
What J.C.Staff does with Part 2 will determine whether the anime becomes a cautionary tale like Berserk 2016, or whether it recovers into something watchable again. Two years is enough time to rebuild. Whether they'll use it is the only real question.
