As the calendar flips to 2026, fans of One-Punch Man are still reeling from the rollercoaster that was Season 3’s first cour. Airing from October 12 to December 29, 2025, the 12-episode run picked up where Season 2 left off, diving deeper into the chaotic Monster Association arc. But just as the finale dropped a cliffhanger teasing the series’ most anticipated showdown, Bandai Namco Filmworks delivered a surprise: Season 3 isn’t over yet. Part 2, the second cour, is officially slated for 2027. This announcement has sparked a mix of excitement and apprehension—will it deliver the punch the series deserves, or will it fizzle like a deflated balloon?
In this article, we’ll break down what to expect from Part 2, the manga material it’s likely to cover, the studio behind it, and any changes (or lack thereof) on the horizon. Drawing from official announcements, fan discussions on platforms like X (formerly Twitter), and industry insights, we’ll explore why this extension could be a game-changer—or a missed opportunity—for Saitama’s bald-headed saga.
A Recap: Where Season 3 Part 1 Left Us
Season 3’s first half kicked off with a strategy meeting among the heroes, escalating into brutal confrontations with the Monster Association’s cadre of bizarre and powerful foes. Episodes like “Monster King” and “Ultimate Lifeform” showcased escalating battles, from Saitama’s casual interventions to intense hero-vs-monster matchups. The animation, however, became a flashpoint for criticism, with many fans labeling it a “slideshow” due to static frames and limited fluidity—echoing complaints from Season 2 but amplified by the six-year wait since 2019.
The finale, Episode 12 (“Ultimate Lifeform”), ramped up the stakes, ending on a high note with improved action sequences that hinted at potential redemption. Post-credits, the reveal of Part 2 came with a teaser trailer and a striking key visual pitting Saitama against a cosmic-empowered Garou, reigniting hype for the arc’s climax.
What to Expect: Epic Battles and Philosophical Punches
If Part 1 was the setup, Part 2 promises the knockout. Expect a torrent of high-octane action as the Monster Association arc hurtles toward its conclusion. Key highlights could include:
- Flashy Flash and Speed-o’-Sound Sonic’s Ninja Saga: Deeper dives into the ninja village backstory, with fluid swordplay and revelations about their shared past.
- Hero Upgrades and Downfalls: Characters like Child Emperor, Zombieman, and Metal Knight will face grueling tests, showcasing their limits against dragon-level threats.
- Garou’s Evolution: The “Hero Hunter” transforms into his cosmic form, blending raw power with a twisted sense of justice. This sets the stage for profound themes of heroism, monstrosity, and what it means to be “strong.”
- Saitama’s Spotlight: The titular one-punch hero will finally step into the fray, delivering his signature boredom-shattering blows. The Saitama vs. Garou fight isn’t just a brawl—it’s a philosophical clash, questioning the value of struggle in a world where victory is effortless.
With another 12 episodes likely (matching Part 1’s structure), Part 2 could wrap the arc while teasing future storylines, like the God entity or the Neo Heroes. Fans on X are buzzing: one user lamented, “OPM season 3 part 2 KV… Why are they ragebaiting us? 😭” [post:19], while others hold out hope for “the most anticipated fight in the series” .
The two-year gap to 2027 offers breathing room for polish, potentially addressing Part 1’s pacing issues and delivering more consistent spectacle. However, skepticism abounds—will the extra time translate to quality, or is it just delaying the inevitable?
Manga Material: From Chapter 117 to the Arc’s Explosive End
One-Punch Man Season 3 adapts Yusuke Murata’s manga remake of ONE’s webcomic, known for its stunning artwork and expanded narratives. Part 1 covered roughly Chapters 84 to 116, focusing on the initial invasion and mid-tier battles . This leaves a wealth of material for Part 2:
- Chapters 117-130: Escalating hero-monster skirmishes, including Atomic Samurai’s rematch and the emergence of key players like Blast.
- Chapters 131-150: Garou’s power-ups, psychic showdowns with Tatsumaki, and the heroes’ desperate alliances.
- Chapters 151-163+: The arc’s peak, with Saitama’s intervention, time-bending twists, and Garou’s redemption arc.
Murata’s detailed panels—full of dynamic poses and intricate destruction—set a high bar. Part 1 made some controversial changes, like reverting to an earlier version of the Child Emperor vs. Phoenix Man fight in Episode 9, which confused manga readers by omitting later expansions . If Part 2 follows suit, it might streamline the story for TV pacing but risk alienating purists. As one Reddit thread noted, “Season 3 seems to cover around vol. 23-27” , suggesting Part 2 could conclude the arc without rushing.
For newcomers, this means a self-contained epic, but manga fans might appreciate how the anime interprets Murata’s visuals, especially Garou’s cosmic design.
Studio and Production: J.C. Staff Returns, But Will It Step Up?
J.C. Staff, the studio behind Seasons 2 and 3, is confirmed to helm Part 2 . This continuity has fans divided—Season 1’s Madhouse animation was legendary for its sakuga (high-quality animation sequences), but J.C. Staff’s efforts have been criticized for relying on CGI and static shots. Director Shinpei Nagai, new to the series for Season 3, has addressed concerns on social media, urging tempered expectations .
No major staff changes have been announced for Part 2 . The core team, including scriptwriter Tomohiro Suzuki and character designer Shinya Hasegawa, remains. However, Episode 12 of Part 1 showed noticeable improvements in fluidity and impact , hinting that feedback might influence the sequel. With J.C. Staff often juggling multiple projects, the 2027 delay could allow for better resource allocation—perhaps more in-house animators or refined storyboarding.
Fan sentiment on X reflects the tension: “Please cancel the anime. Season 3 Part 2 is going to be another terrible production” [post:26], contrasted with optimistic takes like “I have full faith in JC Staff for part 2” [post:23]. Industry leaks suggest the split was planned early, giving the team time to “cook” the Saitama-Garou clash . Yet, as one source warns, “More time doesn’t automatically mean better quality” .
Changes Made and Expected: Evolution or Stagnation?
In Part 1, subtle shifts included enhanced sound design (e.g., JAM Project’s opening theme “Get No Satisfied!” featuring Babymetal) and minor plot tweaks for flow. The Phoenix Man alteration sparked debate, prioritizing the webcomic’s tone over Murata’s redraws . For Part 2, expect similar adaptations—perhaps condensing side stories to focus on Garou’s arc.
No sweeping overhauls are confirmed, but the extended timeline could invite refinements. Fans hope for Madhouse-level animation cameos or guest directors, though that’s unlikely. If J.C. Staff listens to the backlash, we might see more hand-drawn action and less reliance on effects. As ScreenRant notes, “If done right, it’ll redeem the series” , but risks further alienating viewers if it underdelivers.
The Verdict: A Punch Worth Waiting For?
One-Punch Man Season 3 Part 2 arrives in 2027 amid high stakes. It has the potential to cap the Monster Association arc with the flair it deserves, blending humor, heart, and heroism. Yet, lingering animation woes and production consistency remain hurdles. For a series about effortless power, the real challenge is proving it can evolve beyond its past punches.
Whether you’re a die-hard fan or a casual viewer, keep an eye on official channels like the One-Punch Man anime site for updates. In the meantime, revisit the manga or dive into fan theories on X—Saitama’s next one-punch might just be the revival the anime needs.
