The One Punch Man Season 3 trailer is finally here! Get the full breakdown of its animation upgrade, plot details, Garou’s power-up, and what’s next for Saitama.
Finally, the wait is over! After years of wait, the trailer for One Punch Man season 3 is finally here and it is everything the fans have been hoping for! Amazing animation, details of the plot, and glimpses of epic power-up’s. This season is going to give us action, feels and ascension.
First Look: Trailer Breakdown
The official One Punch Man season 3 trailer opens dark and melancholy. This means the season will hit on a more emotional, serious, and darker narrative, contrary to season 1’s comedic levity. It is decided that this season will go all-in on the war between the Hero Association and the Monster Association.
Key character moments in the trailer included:
Saitama, in his trademark yellow suit, still looked unfazed by the chaos around him.
Garou, still bloodied up, but standing strong and putting in the work.
Tatsumaki, the Tornado of Terror, unleashes her telekinetic carnage.
That quick silhouette of Orochi, the Monster King, creates chills down the viewer’s spine.
And the slow pan to Blast, the Rank 1 S-Class hero. Fans are theorizing strongly that this means we will finally get information on Blast’s powers and past. We might not have heard him speak, but he was plain looking epic.
Animation: A New Era Begins

There is a significant upgrade in animation in Season 3. There are rumors circulating that the new season will be animated by Studio MAPPA (known for their work on Jujutsu Kaisen and Attack on Titan: The Final Season), but this hasn’t been confirmed yet. Regardless, we can see what looks like a new jump in animation quality from Season 2, which received its fair share of criticism for its rushed animation.
In the trailer, there were many highlights, notably:
Garou vs. a ton of heroes – A beautifully choreographed multi-angle battle scene.
Saitama is walking down some steps while the city he is walking through immediately crumbles down below him – this indicates the height of the stakes.
A brief but absolutely beautiful psychic battle between Tatsumaki and a Monster Association lieutenant.
It’s evident that Season 3 will be going hard and delivering borderline movie-level animation.
Plot: Monster Association Arc Explained
In the trailer, we can see what manga readers have already known for a while, which is the new season will adapt (what is comic-wise) the Monster Association Arc, which is one of the longest and most insane arcs in the One Punch Man world.
Here’s a spoiler-free breakdown of what we can likely expect:
1. Garou’s Journey Towards Evolution
As a previously self-imposed martial artist and now self-titled Hero Hunter, Garou’s evolution will continue during Season 3. The focus of Garou’s evolution is demonstrating how human he can become by battling high-level heroes and monsters to experience what true fear and strength would feel like.
Just like previously, we should expect to see some deep psychological moments while exploring Garou’s motivations and inhibitions.
2. The Hero Association is being Threatened
With monsters now living within human society, the Monster Association is a looming threat to world peace. Heroes such as Bang, Genos, Atomic Samurai, and Flashy Flash were lost in horrifying battles, and the elite of the monsters.
For Season 3, the story involves tactical warfare, heroes dying, and frantic supply runs, as opposed to the first two seasons of basically just a bunch of monsters running rampant.
3. Saitama’s Existentialism
As the world burns, Saitama’s main quest is internal – the boredom of having no one to fight because he is unbeatable. There will be the obvious comic moments, but what I am excited about is the introspection where Saitama begins to look for something more than just winning: meaning.
Power-Ups and New Abilities
The trailer shows numerous ridiculous power-ups and states reveal Saitama, who becomes a monster for the first time, which is awesome for view-only fans and manga fans alike.
Garou’s Hidden Potential
A clip showing Garou with red eyes and cracked skin appears to be the first stage of his “Monsterfication” process.
Genos Upgraded
The trailer briefly shows Genos donning new weapons, implying an upgrade we’ll see from Dr. Kuseno. Expect insane battles as Genos pushes himself to his limit again—whether or not his body allows him is a different story.
Tatsumaki’s True Power
In one jaw-dropping clip, Tatsumaki is seen lifting an entire building with one arm. As if higher-level threats weren’t enough, Season 3 promises a deeper dive into Tatsumaki’s progression as a psychic, and the backstory behind her mysterious powers.
Fan Reception and Theories
Less than an hour after the trailer dropped, #OnePunchManSeason3 was trending worldwide. Fans flooded Twitter and other social media platforms and their reactions included:
“The animation is GOD-TIER. The serious face on Saitama alone gave me chills!”
“Garou is undeniably the main character of this upcoming season. Can’t wait to see his arc animated!“
“Please, MAPPA, be real!!! That trailer is like a movie!!!”
Here are some of the top theories we’ve found online:
Blast vs Saitama showdown: Will we finally see the strongest hero(???) actually challenged to a fight?
Is Garou the real main character now?? His screen time and evident development in the trailer suggest he’ll be the figure everyone is looking to.
Is Orochi the final boss of this arc…or just the beginning???
Release Date and Where to Watch
Although the trailer doesn’t provide a clear release date, the ending card indicates a release window. One Punch Man Season 3 is likely to premiere in either Spring or Summer 2025, and will be simulcast globally, depending on regio,n on Crunchyroll, Netflix, or Hulu, based on your region and licensing.
Final Thoughts:
Absolutely! Between the awesome animation, darker themes, and character arcs, One Punch Man Season 3 is set to be the biggest and best entry in the franchise as of yet! Whether you’re in it for the laughs, fights, or feels, this season will bring it!
