* ''Anime/DragonBallZ'': [[MadScientist Dr. Gero]] places his brain in a robot body.

* ''TabletopGame/{{Shadowrun}}'' 2nd Edition supplement ''Cybertechnology''. It is possible to replace a person's arms, legs, torso, and skull with cybertech, with only their brain remaining from their original body. However, cybermancy magic must be used to allow the recipient to [[CyberneticsEatYourSoul survive the complete loss of all Essence]] (LifeEnergy).

* ''VideoGame/BioShock'': This is essentially what a Big Daddy is, albeit in a proto-DieselPunk version. A Big Daddy is created by selecting a criminal or other person on the fringe of society, grafting their organs into a huge metal diving suit, and mentally conditioning them to protect [[CreepyChild the Little Sisters]]. Point Prometheus features a lengthy section where [[spoiler:Jack undergoes the process]].[[note]] although seemingly not the non-reversible elements, as seen in the endings where Jack is seen conspicuously suitless. This still doesn't explain what that machine did to his voice box, though.[[/note]]

* ''VideoGame/BioShockInfinite'': The Handymen retain only a few of their original organs in their massive steampunk bodies, most prominently their heads and hearts -- which can be seen via a porthole in their torsos and [[AttackItsWeakPoint shot by wily players]]. Given the powerful but clumsy tech that was used to [[WeCanRebuildHim remake them]], Handymen find this condition ''agonizing.''

* ''Literature/AgentG'' by Creator/CTPhipps: These are called "Shells" (as in Ghost in the). Notably, Shells look identical to human beings on the outside and are seemingly able to live normal lives in-between missions. They are also ImplaccableMan killing machines in the service of the government or PrivateMilitaryContractors.

* ''Franchise/MetalGear'': In between ''VideoGame/MetalGearSolid2'' and ''VideoGame/MetalGearSolid4'', Raiden was converted into a full-body cyborg. He usually leaves his mechanical parts uncovered, with only his face looking consistently organic. [[VideoGame/MetalGearRisingRevengeance Four years later]], full-body cyborgs, such as the [[QuirkyMinibossSquad Winds of Destruction]] and assorted EliteMooks, are much more common. [[spoiler:[[TheDragon Sundowner]] is trying to use the process on ''children'' to turn them into ChildSoldiers, using Raiden's experiences as a template.]]

* ''Series/StarTrekDiscovery'': BridgeBunny Airiam, who appears to be an android, is revealed to be one in [[Recap/StarTrekDiscoveryS2E09ProjectDaedalus "Project Daedalus"]]. After suffering injuries in a shuttle crash, to the point where even parts of her brain have had to be replaced with computer memory that she has to download to offline storage periodically or run out of space. [[spoiler:This allows her body to be taken over by the rogue AI Control, forcing Burnham to MercyKill her via [[ThrownOutTheAirlock airlock]].]]

** "[[Recap/LoveDeathAndRobotsGoodHunting Good Hunting]]": [[spoiler:Yan, a Huli Jing, is forced against her will to become a steampunk cyborg to appeal to the mayor's sexual desires. After killing him, she approaches her human friend, who uses his mechanical prowess to revert her back to her fox form.]]

* ''Manga/BattleAngelAlita'': Many cyborgs are little more than a head on a cyborg body, including the titular character. [[spoiler: Citizens of Zalem are often the inverse, their brains replaced with a chip in an otherwise organic body.]] Akita herself is a particularly extreme example, where as a child the only part of her that was organic was her head. As a young adult, only her brain was organic - and in ''Last Order'', Nova points out that her glial cells have been replaced with a polymer resin that can harden instantly to protect the brain from sudden shock or heat. Only her neurons are organic - less than 3% of her brain. [[spoiler:Eventually, even that 3% is replaced with cybernetics, though she remains human in her consciousness at least.]]

* ''Manga/PandoraInTheCrimsonShellGhostUrn'': The main character Nene is noted to be one among the few people in the world to use a full body prosthetic, in her case in order to deal with a nasty disease that was eating away at her original body. Clarion is another one who is similarly almost fullt mechanical but seems to take the robotic aspects even further. They look mostly human, just with some obvious joints.

** Darth Vader is a {{downplayed}} example. Due to becoming a quadruple amputee in lightsaber duels (right arm to Count Dooku in ''Film/AttackOfTheClones'', remaining limbs to Obi-wan Kenobi in ''Film/RevengeOfTheSith'') and being badly burned by lava on Mustafar, his distinctive suit is [[DarkLordOnLifeSupport as much life-support system as armor]]. His skin was replaced with an artificial substitute, and his VaderBreath comes from a respirator that supplements his borderline-nonfunctional lungs. He's also had some of his vertebrae replaced with artificial substitutes, seen in ''Film/ReturnOfTheJedi'' as a result of XRaySparks from Palpatine's Force lightning.

* [[Fanfic/AbraxasHrodvitnon AbraxasVerse Timeline]]: The official timeline by the author reveals that Kiryu MK I, a HumongousMecha built by Monarch and [[spoiler:[[PeaceAndLoveIncorporated Apex Cybernetics]]]] to fight on Godzilla's side, was built around the ancient bones of Dagon from ''Film/Godzilla2014'', using said bones as an endoskeletal framework. Kiryu consequently becoming possessed by Dagon's resurrected consciousness is a [[https://hrodvitnon.tumblr.com/tagged/kiryu%21dagon recurring headcanon entertained by others on the author's Tumblr]], and the RecursiveFanfiction sequel ''[[https://archiveofourown.org/works/38446570/ Abraxas: The Clash of Silver]]'' furthermore portrays both Kiryu ''and'' [[spoiler:the second Mechagodzilla]] using tissue from [[HalfHumanHybrid the Zmeyevich]] as a telepathic control system with the effect of giving Zmeyevich the potential to control either machine.

* ''Franchise/PowerRangers'': An occasional occurrence, usually applying to TheStarscream.

** Beilart Valance, in both ''ComicBook/StarWarsMarvel1977'' and in the new canon, is revealed to be this. Prior to 2018, the assumption was that he was a human with replaced parts.

* ''Anime/GalaxyExpress999''. Humans can put their minds in machine bodies, to achieve a form of immortality. It is very much a case of CyberneticsEatYourSoul. Some people, realizing this, or tiring of immortality, can return to their human bodies, which are stored on Pluto in the Graves of Ice.
