The Monster Association arc in One-Punch Man is one of the most important and highly anticipated parts of the entire story. In the manga, it is packed with intense battles, surprising moments, and huge character development for both heroes and villains.
Because of this, fans had very high expectations when it was adapted into anime. They hoped to see clean, powerful animation that would do justice to the scale of the fights and the emotions behind them. However, as new episodes rolled out, many viewers began to notice something that disappointed them greatly: off-model cuts that seemed to weaken the impact of key scenes.
“Off-model” is a term used when characters, backgrounds, or action shots do not match the correct design style. In simple terms, it means characters sometimes look different from how they are supposed to. Their faces may be oddly shaped, bodies may look stretched or squashed, and movements may feel stiff or unnatural. In the One-Punch Man Monster Association arc, fans pointed out multiple moments where famous characters looked strange in the middle of important battles. These were not small background mistakes. They happened during major fights that should have been unforgettable.
For long-time fans, this was especially painful. One-Punch Man gained a reputation in its first season for having some of the best action animation in modern anime. The fights were smooth, detailed, and full of energy. Every punch, kick, and explosion felt powerful.
That earlier standard stayed in people’s minds. So when viewers saw rough, off-model frames in the Monster Association arc, it felt like a step backward rather than forward. Many asked how such a popular series could allow such obvious problems to make it onto the screen.

Fans Slam One-Punch Man’s New Episodes as “Slideshow Animation”
On social media, comparisons quickly began. Fans shared side-by-side images of the anime scenes and the original manga panels. The manga art was sharp, detailed, and intense, while the anime version sometimes appeared rushed and inconsistent. This only added to the frustration.
Some viewers accused the studio of cutting corners and not giving the project the time and care it deserved. Others blamed tight deadlines and the heavy workload of animators in today’s industry, saying the artists themselves were likely under extreme pressure.
The Monster Association arc is also very complex. It includes many characters fighting at the same time, in different locations, often underground or in destroyed cities. Animating such a large-scale conflict is not easy. There are monsters with strange designs, heroes with unique abilities, and environments that change constantly. All of this requires a high level of planning and coordination. Some fans believe the animation team simply took on too much at once, resulting in uneven quality across episodes.
Despite these complaints, not everyone was negative. Some viewers said that while certain frames were off-model, the story and voice acting still carried strong emotional weight. They argued that small animation issues should not ruin the experience completely.
Others noticed that some episodes did have excellent cuts mixed in with the weaker ones. This created a confusing situation where quality seemed to rise and fall from one moment to the next, instead of staying consistent.
Another important point in the debate is the treatment of Saitama, the main character. Saitama is very simple in design, but his presence is larger than life. In the Monster Association arc, he appears less often, while the spotlight moves to other heroes and villains.
This made the arc more serious and darker than earlier parts of the story. Some fans appreciated this change, as it allowed side characters to shine. But others felt that without Saitama’s usual comedic balance and perfect animation during his scenes, the series lost part of its identity.
Mixed Reactions Erupt as Viewers Worry About Future Fights in One-Punch Man
The backlash did not come only from hardcore fans. Even casual viewers began to notice that something felt “off” while watching certain episodes. Once people start looking for animation errors, they are harder to ignore.
A strange face here or a poorly drawn arm there can quickly pull the viewer out of the story. Instead of focusing on the danger and drama of the battle, they start thinking about the quality of the artwork. This breaks immersion, which is one of the most important parts of any animated story.
In response to the criticism, there has been no major official statement addressing the off-model concerns directly. This silence has led to even more speculation. Some fans hope that future episodes or seasons will receive a bigger budget and more time for proper animation cleanup. Others are preparing themselves to accept that the anime may never fully match the level of the manga’s art.

Still, the Monster Association arc remains an important part of One-Punch Man’s legacy. Even with its flaws, it continues to keep fans talking, debating, and caring. The strong reaction, whether positive or negative, shows that people still love the world of One-Punch Man and want it to be treated with respect. They are not angry because they hate it. They are angry because they know how great it can be.
In the end, the off-model cuts may be remembered as a disappointing flaw in an otherwise powerful arc. Or they could become a lesson for future productions, reminding studios that fans of major series pay attention to every detail. For now, viewers can only hope that One-Punch Man’s next chapter will rise above these issues and deliver the kind of animation quality that first made them fall in love with the series.

One Punch Man follows Saitama, a hero so powerful he defeats any enemy with a single punch, leaving him bored and searching for a true challenge. He joins the Hero Association and faces increasingly strange and powerful foes, while remaining largely unrecognized by the world. The story parodies typical superhero and shonen tropes with satire and brilliant action.
The first episode of One-Punch Man’s long-awaited new run has finally arrived, and instead of pure excitement, it has opened the door to a heated debate among fans. After several years of silence and anticipation, many viewers expected the series to return with an explosive start full of action, dramatic fights, and fast pacing.
Instead, Episode 1 focused mostly on story setup, dialogue, and atmosphere, with very little fighting on screen. This choice surprised and even upset a large part of the fanbase, especially those who came in expecting an immediate showcase of Saitama’s overwhelming power.
Since its beginning, One-Punch Man has been known for its mix of absurd humor and over-the-top action. Saitama’s ability to defeat any enemy with a single punch turned the usual shonen formula on its head, and fans loved the way the show poked fun at typical superhero stories. Fights in the early seasons were fast, intense, and visually stunning. That is why many people thought the new season would open with a dramatic battle to remind everyone why the series became so popular in the first place. When that didn’t happen, disappointment quickly spread across social media.
The episode instead spent its time reintroducing characters, showing how the world has changed, and setting up future conflicts. While some viewers appreciated this slower approach, saying it helped them reconnect with the story and the Hero Association, others saw it as wasted time.
For them, a first episode after such a long wait should have been packed with memorable moments, not long conversations and quiet scenes. Many fans felt that the creators played it too safe, relying on background information rather than taking a bold step forward.

One-Punch Man Season 3 Premiere Divides Fans Over Lack of Action
Another major point of discussion was the lack of Saitama himself in any real action. The main character appeared, but he did not get a proper moment to shine. For a series that revolves around his unmatched strength, this felt strange to some viewers.
They wanted to see him in action to confirm that the show still understands what made it special. Without that, a few fans even started to question whether the new season might shift its focus away from him and toward side characters or political drama within the hero world.
However, there is also a strong group of fans who are defending the creative team’s decision. They argue that starting slow is sometimes necessary for a bigger payoff later. According to this view, Episode 1 was meant to rebuild the world, remind people of the current situation, and plant the seeds for future chaos.
These fans believe that judging the entire direction of the season based on just one episode is unfair. They point out that some of the best anime arcs in history started with calm moments before diving into intense battles.
There are also practical reasons behind the slower pace. After a six-year gap, the creators may have wanted to make sure that both old and new viewers could follow the story.
Not everyone remembers every detail from the previous seasons, and jumping straight into a complex battle could confuse people who are returning after a long time away. By taking a more careful approach, the show makes itself easier to follow and more welcoming to casual viewers who might not be as hardcore as long-time fans.
Minimal Fights in OPM Episode 1 Ignite Debate on Series Direction
Still, expectations play a huge role in how people feel. When fans wait this long for something they love, their hopes grow bigger with each passing year. Trailers, rumors, and online discussions only add to the hype.
By the time Episode 1 finally dropped, many had already imagined the perfect comeback in their minds. When reality did not match that image, disappointment was almost inevitable. This does not mean the episode was bad. It simply did not deliver what a large section of the audience had built up in their imagination.
The debate over Episode 1 has also raised questions about the bigger direction of the series. Some are worried that One-Punch Man might be losing its original energy. They fear that the humor and sharp satire that once made it stand out might be replaced by a more serious and slower tone.
Others see this change as a sign of growth, saying the story is maturing and trying to explore deeper ideas instead of just repeating the same formula.

In the end, One-Punch Man Episode 1 has done something very powerful, even if by accident. It has made people talk. It has brought the fan community back together in debate, discussion, and passionate arguments. Some are angry, some are hopeful, and some are simply curious about what comes next. This strong reaction proves that people still care deeply about the series, and that in itself is a good sign.
As future episodes are released, opinions may change. Big action scenes are likely still coming, and the slow beginning might make those moments even more impactful.
For now, all fans can do is wait and see whether the series will rise up to meet their expectations or continue taking a more unexpected path. Either way, One-Punch Man has once again found a way to stay in the spotlight, even without throwing a single serious punch.
