8 Man Review: The Cyborg Who Smokes to Stay Alive

The first time I really understood that manga had a history older than me, it was because of a cigarette.

I was a kid flipping through an old reprint that one of my uncles still had on a shelf, and there was this panel of a man in a sharp double-breasted suit, standing still in the middle of an action scene, lighting up. Everyone else in the story was moving. He was just smoking. I didn't get it at all. Why would a hero stop to smoke in the middle of a fight? Years later I learned that the cigarette wasn't a cigarette at all — it was the thing keeping his robot brain from cooking itself. That detail stuck in my head for decades. That's 8 Man. A 1963 manga that turned a hero's weakness into the strangest, most human-feeling part of him.

Quick Take

• One of Japan's earliest cyborg heroes — running in 1963, before Kamen Rider, before most of the genre existed
• The hook isn't the speed (3,000 km/h) — it's that he's a dead detective's mind in a robot body, who has to "smoke" coolant to keep functioning
• Action with a melancholy underneath; rated T (Teen) — violence is present but handled narratively, not graphically

Story Overview

Hachiro Azuma is one of the police force's sharpest detectives. During a confrontation with a vicious criminal, he's shot and killed. That's the end of the man — except it isn't. A scientist named Dr. Tani extracts Azuma's memory and will and pours them into the electronic brain of a super-robot he built. Azuma wakes up as something new: 8 Man, the "eighth" detective of the First Investigation Division, a secret weapon nobody on the force can know about.

By day he goes back to passing as the living Hachiro Azuma — a private detective in a stylish double-breasted suit. When a case turns dangerous, he transforms into 8 Man: a body that runs at 3,000 km/h, packs an atomic reactor, and can reshape its artificial skin and joints to disguise itself as literally anyone. But the same atomic core that makes him unstoppable is also his weakness. His electronic brain overheats. To cool it, he carries cigarette-shaped coolant pellets in his belt buckle and has to "smoke" them periodically — and there are moments where he can't, and the heat starts to win.

The series ran in Weekly Shonen Magazine from 1963 to 1965 across a mix of serialized arcs and standalone cases. It ended abruptly and strangely: artist Jiro Kuwata was arrested for illegal possession of a handgun, and the serialization was cut short. The final installment of the last arc, "Maijin Kozuma," was finished by an assistant ghost-drawing in Kuwata's place. So the ending you read is, fittingly for a story about a man replaced by a machine wearing his face, partly drawn by someone wearing Kuwata's.

Characters

Hachiro Azuma / 8 Man: A detective who dies in the first act and spends the whole rest of the series being someone who is, technically, already dead. His arc is the quiet horror of the premise: he keeps the dead man's name, the dead man's suit, the dead man's job, performing "Hachiro Azuma" for a world that doesn't know Hachiro Azuma is gone. The clever wrinkle the manga builds in — when he stops to smoke his coolant, his old detective instincts and reasoning sharpen. The machine is at its most human exactly when it's keeping itself from breaking down.

Dr. Tani: The scientist who built the robot body and resurrected Azuma inside it. He's the author of 8 Man's existence and the one person who knows what 8 Man really is — which makes their relationship the closest thing 8 Man has to family, and also the source of his condition.

Sachiko and Ichiro: The people in Azuma's everyday civilian life — his secretary and a young assistant — who have no idea the detective they work alongside is a robot. They're the audience 8 Man performs his humanity for, the reason the disguise has to hold.

What I Love About It

I love that the weakness is a cigarette.

Think about how lazy most "robot hero" weaknesses are — a power core that runs low, a battery, a magic crystal. 8 Man's creators did something stranger and better. His vulnerability is that his brain overheats, and the fix is to stop, in the middle of everything, and smoke. And the manga adds a beautiful detail: when he smokes, his human detective reasoning sharpens. So the act that keeps the machine from melting is also the act that makes him most like the man he used to be. The cooling and the thinking are the same gesture.

It's such a specific, almost poetic piece of design for a 1963 action comic aimed at kids. The cultural footprint was real, too — kids who watched the anime adaptation got hooked enough that a tie-in cigarette-shaped solid cocoa candy became a hit. A hero whose defining trait was "stops to smoke" sold cocoa cigarettes to children. The 1960s were a different planet. But strip away the period weirdness and what's left is a genuinely smart idea: a body that betrays you the harder you push it, and a ritual that's part medicine, part habit, part the last thread tying a machine to a dead man.

Memorable Scene ⚠️ Spoiler Warning

The shapeshifting is where the strangeness of 8 Man's body really lands.

His artificial skin and movable joints let him become anyone — the manga describes him super-accelerating to instantly change clothes and shift his face so completely he can pass as a woman. On paper it's a cool spy gadget. But sit with what it means. This is a man who already lost his original body. Now his replacement body isn't even fixed — it's putty. He can wear any face, which is another way of saying he has no face that's truly his. The detective who used to be Hachiro Azuma can look like Hachiro Azuma, or like a stranger, or like a woman on a train, and none of them is more "him" than the others.

That's the panel that stays with me. Not a big action beat — the quiet implication underneath a clever ability. When a hero can become anybody, the story is also telling you he's nobody in particular anymore. For a comic from 1963, reaching that idea almost by accident, through what was supposed to be a fun transformation trick, is the kind of thing that makes me love old manga.

Art Style

Jiro Kuwata's linework is some of the cleanest of the early manga era. His action reads with real kineticism — 8 Man's speed comes through in composition and motion rather than over-explanation — and his quiet, suited civilian scenes have the restraint the melancholy needs. Knowing Kuwata's run ended with his arrest, and that an assistant finished the final chapter, adds a strange weight to looking at the late pages.

Cultural Context

8 Man arrived in 1963, the same era manga and TV anime were both being invented as mass culture. It's recognized as one of Japan's earliest cyborg superheroes, predating Kamen Rider. The anime adaptation, which began airing in 1963, reached English-speaking markets through syndication as 8th Man, with the characters renamed for Western audiences — which is why some older Western viewers know "8th Man" without ever having seen a page of Hirai and Kuwata's manga.

Pros & Cons

Pros

• Historically foundational — a cyborg hero before the genre had a name
• The coolant-cigarette and shapeshifting ideas are genuinely inventive, not just spectacle
• Kuwata's art holds up remarkably well
• Self-contained classic; complete in 5 volumes

Cons

• No licensed English edition of the manga
• Pacing reflects 1960s serialization — modern readers may find it slow
• The ending is abrupt and partly ghost-drawn due to the real-world circumstances of its cancellation
• The smoking-as-heroism framing is very of-its-era — if that pulls you out of it, this won't work for everyone

Is 8 Man Worth Reading?

For sci-fi fans and manga historians, yes — this is a foundational cyborg-hero text, and its best ideas (the cooling cigarettes, the faceless shapeshifter) are smarter than its 1963 date suggests. For general readers, it asks patience with the era's pacing and an abrupt ending. But the melancholy under the action — a dead man performing his own life in a body that can become anyone — still lands.

Who Is This Manga For?

• Manga historians who want to read where the cyborg-hero genre actually started
• Sci-fi fans drawn to the identity question — what's left of a person poured into a machine
• Fans of Jiro Kuwata's art, clean and expressive even sixty years on
• Readers who can read Japanese — there's no licensed English manga edition

Where to Buy

No English release yet. That just means you find it before everyone else does.

There's no licensed English edition of the 8 Man manga — the Japanese print and digital releases are the only legitimate way to read Hirai and Kuwata's original.
