One Punch Man: Who Is Blast And Why He Only Shows Up Briefly?

There’s no shortage of unforgettable Heroes in One Punch Man. Even with so many powerful characters fighting Monsters all across the world, Blast takes the cake for the most mysterious and powerful Hero. Most of the Hero Association’s members have never met him, and fans have spent years speculating over who he is. Also, we have no idea how strong he truly might be, and why he hardly ever appears on the frontlines.

Blast’s brief appearances and secretive lifestyle stand in stark contrast to the series’ many other Heroes, who crave recognition or are constantly in the public eye. Instead, Blast seems perfectly fine working behind the scenes on unknown missions, occasionally revealing himself only when the situation turns truly bad. This has made him the subject of endless theories and given his rare cameos immense weight, every moment feeding both the plot and the audience’s expectations.

Who Is Blast? The Legend At S-Class Rank 1

Blast holds the highest title within the Hero Association: S-Class, Rank 1. This means, officially, he’s considered the strongest Hero of them all. Meaning he is even above the strongest Heroes like Tatsumaki, Bang, or King. In fact, for years, most characters had only heard rumors about him, assuming he was either a myth or someone so strong he simply never needed to help.

It’s only much later in the series that we see any direct evidence of him or learn something about his real personality. Despite his position, Blast is different from other S-Class Heroes. He doesn’t attend Hero Association meetings, avoids public battles, and seems to have no interest in fame or recognition.

As a result, many of the Heroes at the Hero Association question if Blast even exists. But for those few who have seen him in action, it’s clear that Blast is very real — and almost superhuman in his abilities.

Why Is Blast So Mysterious?

Unlike other Heroes who operate out in the open, Blast’s job seems to involve far bigger threats than regular Disaster Levels. He chooses to act only in situations that could affect the entire world or even reality itself. This means while the rest of the Hero Association is busy fighting regular Monsters, Blast is quietly handling cosmic threats or traveling between dimensions to keep hidden disasters away.

In a sense, he acts as the ultimate safety net, stepping in only when absolutely no one else can handle the situation, just like Saitama. Blast’s mysterious nature is also a plot device in One Punch Man.

By keeping him mostly off-screen, the creators build up an aura of legend that surrounds everything he does. This results in every short appearance or cryptic message from Blast sending shockwaves through the hero community and the audience.

The True Nature Of Blast’s Missions

We later learn that Blast is not ignoring the world’s dangers. Rather, he’s actively investigating the highest-level threats, like the collection of mysterious cubes and the activities of beings like God. Often, these threats aren’t visible to the public or even the Hero Association, which is why he seems to vanish for a long time.

This makes his sense of duty different than anyone else’s because he’s prioritizing risks that could destroy humanity instead of just the visible Monsters. Another reason why Blast rarely appears is because of his ability to travel through space and dimensions. This unique ability allows him to tackle threats completely out of reach for normal Heroes.

He recruits partners and operates according to a completely different set of rules and risks. So, rather than being lazy or indifferent, Blast is often quite literally in another world, doing things no other Hero could understand or survive.

Why Does He Only Show Up Briefly?

The rare moments when Blast appears align with truly major events — times when even the S-Class heroes are overwhelmed or when the threat is on the verge of breaking reality. For example, his first proper appearance comes during the fight with Elder Centipede. Even then, he doesn’t directly battle the Monster. Instead, he’s focused on cosmic-level duties.

We can say that his encounters are quick, decisive, and always leave both the Heroes and the readers with more questions than answers. But this narrative choice serves a purpose. By keeping Blast’s appearances rare and impactful, the creators ensure his mystique is preserved.

He’s basically a legend for other Heroes to strive for, even as the main story stays focused on Saitama. Blast’s brief appearances hint at a bigger universe and more complex dangers waiting in the shadows of the One Punch Man world.

Will We Ever See Blast In Action?

With every new arc, fans hope to see Blast fight at full power or learn more about his past. The hints we get, like his immense speed, intelligence, and dimension-jumping abilities, suggest that when his true battle finally comes, it will dominate even the wildest fights in the series so far.

For now, however, Blast remains a tempting mystery. And all we know is that he's a protector, strong enough to be even recognized by Saitama.
