You have seen Saitama punch his way through monsters and gods like it is nothing. The moment he appears, the fight ends in one punch. Because of this, you might think he has no limit. But the story of One-Punch Man is not just about him winning. It also asks one very big question. Is there any limit to Saitama’s power? Or is he truly endless?

Let me walk you through everything that the manga, anime, and creators have shown about this mystery.

What Is a Limiter in One-Punch Man?

In the One-Punch Man world, there is a thing called a “limiter”. Dr. Genus, who appears early in the story, talks about this. He is a scientist who studied how people get strong. According to him, all humans are born with a limit. This is called the limiter. It is like a cap that stops them from growing too powerful.

This limiter is there for safety. If someone keeps getting stronger forever, they will lose control or even destroy themselves. So nature gives them a limit. You can train and become very strong, but after a point, you stop.

What Happened to Saitama’s Limiter?

Dr. Genus says something shocking. He believes Saitama has broken his limiter. Not just stretched it or pushed it. He completely removed it. That means there is no cap on his growth.

He trained very hard. As you know, he did 100 push-ups, 100 sit-ups, 100 squats and ran 10 km every day. He did this for three years without rest. It sounds funny but in the story, this extreme training pushed him beyond the limit.

So now, Saitama can keep getting stronger. There is no line where he stops. During his fight with Cosmic Garou, he even kept increasing in strength during battle. In one moment, he punched a version of himself from the past—and won. That means the present Saitama had already grown much stronger than just a few minutes ago.

Is There Any Sign of a Limit?

Now here’s the thing. Some fans ask: If he is limitless, then why does he say things like “I went all out”? Is he hiding his true strength? Or does he also have a personal idea of what “maximum” means?

In one chapter, Saitama does say he went all-out. But this line may not mean that he hit his real limit. It could mean he just used more force than usual. Because even when he goes “serious”, the enemy never survives. So it is not clear if this “all-out” is truly 100% of what he can do.

What Other Characters Say

Dr. Genus said no one else has removed their limiter before. Only Saitama. Garou came close. In his monster form, Garou broke his limiter partially. But even he could not match Saitama.

There is also a monster named Psykos. She believed that monsters can break their limiter by pushing themselves near death again and again. But even those monsters did not become like Saitama.

That means breaking the limiter is rare. And full removal is even more rare. Only Saitama seems to have done it.

Why He Keeps Getting Stronger

The main thing is this. Saitama keeps growing because he has no limiter. In the fight with Garou, each time Garou copied Saitama’s moves, Saitama just grew stronger. His growth speed went beyond any rule.

This is shown again and again. He sneezed and destroyed Jupiter’s moon. He moved faster than time. His strength has no rule anymore.

So the story shows this: Saitama’s power is not stuck. It is active. It is rising. The more he fights, the more powerful he becomes.

What the Creators Want to Show

One important point. The author of One-Punch Man, ONE, created Saitama as a joke on superhero stories. In other stories, heroes grow step by step. But Saitama starts at the top. He is bored. No one can match him. So the story is not about fights. It is about the sadness of being too strong.

That’s why we may never see a clear number for his limit. Because the joke is that there is no number. His strength is a tool to show how empty life becomes when there is no challenge.

Conclusion: Is There a Limit?

Let me keep it very simple now.

Saitama has removed his limiter. That means he has no fixed end to his power. He keeps growing. Every time he needs more power, he gets it. That is how he beat Garou. That is how he became stronger than his past self in just minutes. No other character has shown this type of endless growth.

But the story never says his power is truly infinite. It shows that he grows when needed. And it shows that no one has reached his level yet.

So if you ask me, does Saitama have a limit? My answer is this:

He did. But he broke it. And now, even the story does not know where he ends.
