One Punch Man: The Anime That Made Strength Meaningless — and Why That’s Brilliant
By Yoshi | Japan Unveiled
There is a joke at the centre of One Punch Man that should not sustain a series for more than ten minutes.
The joke: the protagonist is so powerful that he defeats every opponent with a single punch. Every fight is over before it begins. The dramatic tension that is the primary engine of every other action manga — the uncertainty of the outcome, the protagonist pushed to their limit, the desperate final effort that produces victory — is categorically absent. There is no tension. There can be no tension, because the outcome is always the same: one punch, one victory, one more enemy who underestimated the bald man in the yellow suit.
And yet One Punch Man — the webcomic by ONE that was adapted into a manga by Yusuke Murata and subsequently into anime — is one of the most loved and most discussed action manga of the past decade. It has sold over thirty million copies. The anime adaptation is consistently rated among the finest-looking animated works ever produced. International fans cite it with genuine enthusiasm.
The joke works. The joke sustains a series of hundreds of chapters and multiple anime seasons. The joke reveals, in the specific way that only great satire can reveal, something true about the genre it is satirising and something true about the human experience it is documenting.
I want to explain how.
What One Punch Man Is
One Punch Man was created by ONE — a web manga creator who began publishing the story on his personal website in 2009, initially in a rough visual style that attracted enormous online readership despite its technical limitations. The story’s premise and its comedic logic attracted the attention of manga artist Yusuke Murata, who offered to redraw the story in professional manga style for publication in Young Jump Web Comics. The collaboration — ONE providing the story and Murata providing the artwork — produced one of the most visually extraordinary manga currently in publication.
The premise: Saitama is an ordinary man from the city of Z who decided, on a whim, to become a hero. He trained so hard that he lost all his hair and became the most powerful being in the universe. He can defeat any enemy with a single punch. He is registered as a C-Class hero in the Hero Association — the bureaucratic organisation that manages professional heroism — and spends his days fighting monsters, shopping for bargains, and experiencing a profound and debilitating ennui.
The ennui is the key. Saitama is not satisfied by his power. He is miserable. Not because he wanted to be powerful and failed — he succeeded completely — but because the achievement of absolute power has produced the specific emptiness of having no challenge left to face. Every fight is already over before it begins. The experience of genuine struggle, genuine fear, genuine effort — the experiences that constitute a meaningful challenge — are permanently unavailable to him.
The Satire Dimension: What ONE Is Saying About Shōnen Manga
To fully appreciate One Punch Man, you need to understand the genre it is parodying — because its specific joke is a specific argument about the conventions of shōnen action manga.
The standard shōnen action formula — which I have written about in various contexts across this blog — involves a protagonist who grows through struggle. The hero begins weak, faces opponents who are stronger, nearly loses, finds new strength or new technique or new resolve, and ultimately wins. The drama is in the gap between the hero’s current power and the opponent’s power — the specific uncertainty of whether this time, the hero will be strong enough.
This formula — replicated across Dragon Ball, Naruto, One Piece, My Hero Academia, Demon Slayer, and virtually every other major shōnen franchise — is effective precisely because it generates genuine dramatic tension. The reader genuinely does not know if the hero will win, and the specific quality of the reader’s investment in the outcome is what makes the climactic battle emotionally resonant.
One Punch Man removes this tension completely, and the removal is a demonstration. By showing us a protagonist for whom the formula cannot work — for whom every battle is won before it begins — ONE shows us the formula by its absence. We see, in Saitama’s boredom, what the formula is actually providing: the specific pleasure of struggle, of meaningful effort, of the gap between current capability and required capability.
The satire makes explicit what the genre relies on implicitly: that the story is not really about the fights. It is about the hero’s growth, about the specific experience of being tested and found wanting and finding more within oneself. Power itself — the end state of the growth — is not interesting. Only the path is interesting.
Saitama arrived at the destination. And the destination is lonely.
The Visual Achievement: Murata’s Art
A discussion of One Punch Man cannot avoid the extraordinary visual quality of Murata’s artwork — which is consistently cited as the finest action manga artwork being produced.
Yusuke Murata has drawn manga professionally since the 1990s, with his Eyeshield 21 (a football manga for Shōnen Jump) establishing his reputation for dynamic sports action. The collaboration with ONE on One Punch Man has produced something categorically different from anything Murata had previously attempted — artwork that is not simply very good but that pushes the limits of what the medium can visually achieve.
The specific qualities of Murata’s One Punch Man artwork: the character designs that communicate personality instantly and completely; the monster designs that are simultaneously absurd and genuinely threatening; the battle choreography that makes the physics of superhuman combat legible and kinetically exciting even when the outcome is predetermined; and the specific quality of the Saitama action sequences that convey both the effortlessness of the protagonist’s power and the devastation of its effect in simultaneous panel compositions of extraordinary skill.
The paradox of the Saitama action sequences: they are visually spectacular despite depicting something that should be boring (an effortless victory). Murata achieves this by rendering the effortlessness itself as spectacle — the specific visual grammar of Saitama’s punch is so compressed, so minimally animated, that its contrast with the elaborate pre-battle dramatics of his opponents makes the resolution more comic and more impressive simultaneously.
The anime adaptation — the 2015 Season 1 produced by Madhouse, specifically the animation of the Boros fight in the final episode — is frequently cited as among the finest action animation ever produced. The specific commitment of the animation staff to realising Murata’s artwork in motion produced sequences that are both technically extraordinary and emotionally resonant in ways that action animation rarely achieves.
Genos and the Mirror
The structural solution to the problem of Saitama as a protagonist — too powerful to generate conventional dramatic tension — is Genos: the young cyborg who becomes Saitama’s disciple and who provides the conventional dramatic tension that Saitama cannot.
Genos is strong. Genos is impressive by any conventional measure. Genos trains, develops, and genuinely struggles against opponents who test him. His character arc follows the shōnen formula reasonably closely — he has a mission (revenge against the cyborg who destroyed his hometown), a specific goal (to become stronger), and a specific mentor whose guidance he seeks.
But Genos is always inadequate. However impressive his development, the enemies that genuinely threaten Saitama are always beyond Genos’s capability. The specific frustration of being strong but not strong enough — the specific emotional experience of the shōnen protagonist who is still on the growth curve — is Genos’s permanent condition.
Through Genos, we understand what Saitama has escaped. Through Saitama, we understand what Genos would lose if he actually reached the destination.
The Hero Association: Bureaucracy and Heroism
One Punch Man’s most sustained social satire is directed not at the shōnen genre but at institutional bureaucracy and the specific ways that formal systems misallocate recognition.
The Hero Association — the organisation that registers and ranks heroes, coordinates monster responses, and manages the public face of the professional hero industry — is a bureaucratic institution with all the specific dysfunctions of bureaucratic institutions. It ranks heroes based on performance metrics that systematically undervalue Saitama’s contributions (because his victories happen so fast that no one observes them), places excessive weight on public recognition and media coverage rather than actual effectiveness, and creates institutional incentives for heroes to prioritise their rankings over actual heroic behaviour.
Saitama, because he saved the city in ways that were not publicly visible, is ranked as a C-Class hero despite being the most powerful being alive. The S-Class heroes — the officially recognised elite — are weaker than him but more publicly visible. The institutional ranking inverts the actual hierarchy of power.
This inversion — the capable but unrecognised protagonist navigating an institutional system that fails to acknowledge his actual contribution — is a genuinely universal experience. The specific resonance of One Punch Man’s bureaucratic satire extends far beyond the superhero setting: it is a specific accurate description of how many institutional systems actually work, and why genuine merit and institutional recognition so often fail to align.
What One Punch Man Ultimately Argues
The most remarkable thing about One Punch Man is that it is, beneath the satire and beneath the extraordinary action, a genuinely compassionate story about a genuinely lonely person.
Saitama achieved what he set out to achieve. He is the strongest. And it has made him profoundly isolated — unable to connect with other heroes through the shared experience of struggle, unable to find genuine opponents, unable to feel the specific aliveness that genuine challenge produces.
The series’ most emotionally resonant moments are not the fights — they are the moments of human connection. The specific friendship between Saitama and Genos, in which Genos’s earnest devotion and Saitama’s laconic acknowledgment produce a genuinely warm relationship. The moment when Saitama tells the crab monster that he has no reason to fight — that his only connection to heroism is a choice he made for himself, without external validation. The specific scene when Saitama cries during a sale at the supermarket because his emotional register has been calibrated to find meaning in small things — because the large things no longer produce it.
One Punch Man is asking: what does it mean to have what you wanted and find that it is not what you needed? What do you do when the goal you pursued has been achieved and the achievement is empty?
The answer the series suggests is not despairing: it is to find smaller things. To appreciate the moments of genuine human connection. To make the choice of heroism again, not because it will make you powerful, but because it was a good choice the first time.
Saitama is the strongest person in the world. He goes grocery shopping. He plays video games with Genos. He occasionally saves the world, almost by accident.
It is, genuinely, a beautiful story.
