Based the manga series ''8 Man'' by Jiro Kuwata and Kazumasa Hirai, this 1963 anime tells the story of a private investigator named Hachiro Azuma (Brady in the US), ambushed by criminals and run over by a car. As he lies dying, a mysterious scientist rescues him and gives him a [[WeCanRebuildHim new cyborg body]].

Now empowered beyond ordinary men, Azuma becomes (all by himself) the secret 8th division of the Tokyo Police. His only superior is bureau chief Tanaka (called Chief Fumblethumbs, of all things, in English). Now called 8-Man ("Eighth Man", in English, because according to the dub he was the eighth cyborg attempt -- and the first one to work!), he has the [[StockSuperpowers usual array]] of powers: SuperStrength, SuperSpeed, plus the unusual ability to [[HelpingHands detach and remotely control his limbs]]. In a detail that would never get past kid-vid censors today, 8-Man recharged his power supply using "special cigarettes". He spent much of his time fighting an array of goofy enemies ranging from communist spies and robot bats to gangsters with bizarre names right out of ''ComicStrip/DickTracy.''

Although the animation was average for a TV series of its time (it ran from November 7, 1963 to December 12, 1964 in Japan), by modern standards it is laughable and crude. In addition to being in black and white, its production crew had almost no experience with cel animation and took several episodes to gain any skill with the form. Even then it was of low quality, with a minimal frame rate, low detail, and wooden movement.

Despite this, it is still viewed with a certain amount of nostalgia in both Japan and the United States, so much so that there was actually a (reputedly awful) LiveActionAdaptation produced in 1992.

It also prompted a DarkerAndEdgier {{Revival}} {{OVA}} series in 1993, ''8th Man After'', which was released in English by Creator/StreamlinePictures. This has joined its originator as a CultClassic due to its unique blend of dark CyberPunk and over-the-top SuperHero themes. It is also remembered for its mock-worthy DrugsAreBad themes - CyberneticsEatYourSoul because they are unusable without PsychoSerum. Eight Man is resurrected to fight them, fueled by SuperSerum. Just Say NO to PsychoSerum - Use SuperSerum! This could have all been avoided by [[FridgeLogic simply distributing the "safe" serum.]] Then lots of people could have cybernetics. But ReedRichardsIsUseless. [[MST3KMantra It's just an anime, I should really just relax]] and enjoy the ultraviolence.

Along with ''Anime/AstroBoy'', ''Anime/{{Gigantor}}'' and ''Anime/SpeedRacer'', ''8th Man'' is historically significant as one of the first anime series to be distributed in the United States. The American version's [[ImportationExpansion newly animated]] [[ExpositoryThemeTune opening sequence]] was the first professional animation work done by Creator/RalphBakshi.

Any similarities to another story about [[Franchise/RoboCop a dying cop revived by Science]] are purely coincidental.

----
!! The original series contains examples of:
* ExpositoryThemeTune: The theme to the English dub combines this trope and NeverTrustATrailer, as the theme and ([[ImportationExpansion American animated]]) opening sequence described Eight Man fighting aliens (which he never does) and flying (which he can't do). A very young Creator/RalphBakshi was responsible for the new (and OffModel) opening.
* ItRunsOnNonsensoleum: 8 Man recharges his super-batteries or whatever by smoking radium-laced cigarettes.
* SdrawkcabAlias: His secret identity is named Tobor.
* WeaksauceWeakness: Eight Man has to smoke (or eat) what appear to be cigarettes to keep his powers running. Great when he's facing a firing squad, but ''what if kids see him smoking and he sets a bad example?''
** Note that the latter issue is only thanks to ValuesDissonance with the time period the character was originally created in. 60s Japan was a time when people still believed cigarettes were ''good for you''.

!! 8th-Man After contains examples of:
* CyberneticsEatYourSoul: Cyborgs routinely run rampant because the cybernetic link to the nervous system along with the massive boost in strength unhinges most people's minds. Eight Man, being a ({{Bishonen}}) PhlebotinumRebel with "good cybernetics" is able to escape these effects and battle the evil MegaCorp producing them.
* DrugsAreBad: Used by the OVA in place of CyberneticsEatYourSoul: it's not the cybernetics per se that drives the users crazy, but the massive quantities of PsychoSerum they have to take to use the implants effectively. Eight Man makes do with good-old SuperSerum.
* [[spoiler:KilledOffForReal: In ''8th Man After'' it's revealed that Azuma was deleted from his cyborg body with no explanation as to how or why he was deleted, the only remaining trace being his name, and his successor Hazama inheriting the body. However, combining statements from Sachiko and Professor Tani suggests that Azuma eventually wasn't able to cope with his situation and died. Since Tani had the body to begin with, it's possible that he ended up ''euthanizing'' Azuma.]]
* PutOnABus: Azuma disappears not a minute into the OVA, never to be seen again.
** [[spoiler: BusCrash: We later discover that Hazama isn't a totally new Eight Man, but inhabits the original body. Azuma's mind had been deleted by persons and methods unknown.]]
* RoaringRampageOfRevenge: In ''After,'' Hazama remembers the night his fiancee was murdered and how he promptly hunted down and killed those responsible. The memory of the murder unfortunately can trigger UnstoppableRage.
* SuperSerum: Used in the OVA.
* WhatTheHellHero: Sachiko chews out Eight Man for using excessive force in killing a rampaging cyborg football team, going so far as to call him scarier than the cyborgs he killed. [[MoralDissonance The cyborgs that were in the midst of slaughtering dozens of innocent fans in the stands and were just about to do the same to Sachiko before Eight Man arrived.]]
