One-Punch Man

Saitama trained until he lost his hair and became strong enough to end any fight immediately. The result is not satisfaction but a profound boredom: no opponent can give him a contest, and nobody recognises what he has done.

He registers with a hero association, is ranked poorly because he fails the written examination, and spends the series as an unrecognised presence in other people's battles.

He wins every fight in one hit, and the only consequence is that nothing is interesting any more.

Devmark’s reading — not a quotation from the book

The premise inverts the genre's fundamental mechanism: if escalating power is what action narratives are built on, a protagonist who has finished escalating cannot have a story.

The series solves this by making everyone else the story, and Saitama's irrelevance to his own narrative is the running structural joke.

Fights are built up at length with elaborate opponents, stakes and preparation, and then resolved in a panel.

The deflation is reliable and remains funny because the build-up is always sincere. The series commits fully to the tension it is about to discard. Murata also draws the build-up at maximum effort every time, which means the joke costs more to set up than almost any other gag in the medium.

The redrawn version is among the most technically spectacular action art in the medium, with enormous detail, extraordinary sense of scale, and choreography that rewards close reading.

The contrast between the drawing's seriousness and the plot's dismissal of it is much of the joke, and Murata is plainly in on it.

ONE's own version, drawn crudely and still updating separately, is a distinct work with different pacing and considerably more emphasis on the comedy.

Many readers prefer it, and the two have diverged substantially. The webcomic is the purer expression of the idea and the redraw is the more impressive object.

The cyborg who appoints himself Saitama's disciple, and the hero association's ranked roster, supply the emotional investment the protagonist cannot.

Several supporting heroes — particularly those who are weak and continue anyway — carry the series' actual argument about what heroism costs. Mumen Rider, a hero with no powers at all who continues to intervene anyway, is the clearest statement of that argument and the series' most admired character.

Saitama's real problem is not boredom but obscurity: he saves people constantly and is credited with nothing, and the series takes this seriously.

The gap between what he does and what he is seen to do is the source of most of the genuinely affecting material, and it is handled without self-pity.

The hero association ranks, evaluates, publicises and monetises its members, and the series is consistently satirical about an institution that measures the wrong things.

Saitama's low rank despite his ability is the joke's engine, and the satire of performance metrics is sharper than the premise requires.

Murata redraws at an irregular rate and frequently revises chapters after release, sometimes substantially.

The series is ongoing and the publication history is unusually messy, with several arcs existing in multiple versions. Readers approaching it now should be aware that chapter numbering has shifted more than once, and that several arcs exist in a revised form that supersedes the original release.

Both concern overwhelming power treated as uninteresting, and this is the more satirical while Mob Psycho is the more emotionally substantial.

Readers who want the idea at its funniest should read this; readers who want it developed into something about growing up should read the other.

The first animated season is widely regarded as exceptional, with fight animation of unusual quality; the second, made by a different studio, was less well received.

The first season is a reasonable entry point and captures the tone accurately. The first season also compresses the early volumes efficiently, so it covers a substantial portion of the material available at the time.

Readers who want a genuine satire of the action genre executed with complete technical commitment.

It is ongoing and messy, and the idea is fully legible from the first few volumes. Readers who want the joke without the commitment can read those and stop without loss.
