->''"I'm afraid I didn't land very well. Fortunately I had programmed my earliest robots to save my life at any cost! They found me in a lonely alley before the spark of life had fled. [...] I shall never forget the sight that greeted me upon regaining consciousness! [...] I remember I felt well -- even strong -- although I had this incredible sense of detachment. And then, I lifted my hand to my face... ''but it was no longer my hand!''"''
-->-- '''The Machinesmith''', ''ComicBook/CaptainAmerica # 249''

Alas! An ally or loved one is bleeding to death and about to die ([[HeroicSacrifice Heroics]] [[DeadSidekick optional]])! With little time and no other options, the heroes are faced with only one alternative... an Emergency Transformation.

Humanity is not absolute - it is both graded and transitional. The heroes, [[SuperEmpowering having access to machines, magics, or curses]] capable of [[ViralTransformation transforming someone]] into something less and/or more than human, will be forced to choose whether they let their friend die human or live on as something else.

If the ally is unconscious the decision is usually made for them. This tends to be especially tragic or anguishing as the transformee usually [[WhatHaveIBecome deeply hates his new form]], be it because it's [[OneWingedAngel monstrous]], [[IHateYouVampireDad associated with other unpleasantness]], or [[BlessedWithSuck weaker than their previous form]]. Expect the character to angst about his {{Metamorphosis}} endlessly, even if this isn't the case and [[CursedWithAwesome he's actually better off than before]].

However, the ally may have to go through the decision of making the choice between the sweet release of death, or a non-human life with super powers and possibly even [[WhoWantsToLiveForever eternal life]]. ([[CursedWithAwesome Gee, what a tough call]].) Occasionally though, [[BlessedWithSuck it is]] and there will be much blame to give out because of it. You'd be surprised how distressing it can be when one is literally UnableToCry.

There are a few general variations:
* [[OurVampiresAreDifferent Vampires]], or [[NotUsingTheZWord something similar]], will [[SuperEmpowering transform]] a [[ILoveYouVampireSon friend or loved one into same]]. This rarely ends well. If it isn't to cries of "IHateYouVampireDad", the sire will discover that junior [[AlwaysChaoticEvil takes after]] [[MeaningfulName Grandpa Bloodlove]] instead of [[FriendlyNeighborhoodVampire himself]].
* A literal magical transformation, demonic transformation, or some other spell that will give the recipient a new bill of health... if not a [[{{Animorphism}} new]] [[{{Transflormation}} species]] too.
* [[LegoGenetics Genetic modification]]. Whether via SuperSerum, GeneticEngineeringIsTheNewNuke, or more creative methods; they are transformed into a {{mutant|s}}, HalfHumanHybrid, or even a [[MixAndMatchCritters Mix-and-Match Critter]]. Their mental stability will directly correlate to how outwardly human they stay.
* WeCanRebuildHim! [[ArtificialLimbs Cyborgs]] and the like will [[WeCanRebuildHim upgrade]] all the damaged tissue with cybernetics or [[ManInTheMachine encasing the person in a robot body]]. Not pleasant, as CyberneticsEatYourSoul, and XRayVision [[SenseLossSadness doesn't quite compensate inability to smell]], and there's some LossOfIdentity, but who gives a damn!
* Another variant involves [[BrainUploading digitizing the mind]] ([[OurSoulsAreDifferent soul]] [[CyberneticsEatYourSoul optional]]) into [[CursedWithAwesome a computer]] or [[ArtificialHuman synthetic body]].
* A relatively mundane, real-life medical procedure, like an organ transplant or [[SuperhumanTransfusion blood transfusion]], for whom the only matching donor is a [[{{Mutants}} biologically abnormal]] relative. [[SideEffectsInclude It carries side effects]] ranging from the purely cosmetic to the {{harmful|Healing}}.

Expect these to [[CantStayNormal be permanent]], and for the [[BlackShirt naturally inclined to evil]] to think it makes them [[TranshumanTreachery superior]] to [[MugglePower "mundane" humans]], while heroes will be {{Pro Human Transhuman}}s. Frequently has a [[PsychoSerum high]] rate of [[WithGreatPowerComesGreatInsanity insanity]] and [[CameBackWrong failure]], at the least it makes the vain [[BeautyToBeast very distraught]]. Definitely a setup for lessons in WhatMeasureIsANonHuman, many stories of the [[AnAesop fable]] kind have characters [[KarmicTransformation cursed]] this way for harming a non-human creature. A character can go through the StagesOfMonsterGrief and get an [[EpiphanyTherapy epiphany]] that IAmWhatIAm, which ironically enough [[EpiphanicPrison may trigger a return to human status]]. Someone who greets ''any'' emergency by transforming is probably just a OneWingedAngel.

Compare CurseThatCures, when a sick or injured character voluntarily (and without the pressure of being under threat of immediate death) seeks a {{Curse}} because it can cure them as a side effect. See also PowerUpgradingDeformation.



[[folder:Anime & Manga]]
* Alphonse Elric, in ''Manga/FullmetalAlchemist''. His entire body is taken by the Doors of Truth, so Ed does the only thing he can and binds his soul to a suit of armor conveniently standing in the corner. [[spoiler:This isn't actually permanent. Al gets his real body back four or five years later, at the end of their quest.]]
** Alphonse again in a later episode of [[Anime/FullmetalAlchemist the 2003 anime continuity]]. [[spoiler:Kimblee starts a chain reaction that will turn Al's armor body into a bomb. Deciding that the only way to save him is to change his composition into something else but lacking the ability to perform a more traditional transmutation, Scar gives up his arm to transfer its valuable contents to Al, making him into a living Philosopher's Stone.]]
* In one episode of ''Anime/BloodPlus,'' Saya does this with [[spoiler: her adoptive younger brother Riku]]. Despite herself and Haji being shining examples of {{Friendly Neighborhood Vampire}}s who [[VampireRefugee hunt bad vampires]], she beats herself up for it. It is however slightly tragic in that he will never [[spoiler: grow up, becoming an undead Pinocchio. Also he pretty much loses his personality, instead becoming a slave with no desire except to serve and protect Saya. Except... the ''true'' tragedy is it only kept him alive a little longer- Diva decided to ''rape'' and murder him shortly afterward]].
** She also did this once before by accident, on Haji. He's exactly the same as before. In fact, the reason he needed this trope is the same kind behavior afterward
** Diva does this too. Some by choice, some by force. None of them had any complaints.
* The entire premise of ''Manga/{{Bleach}}'', at least for the living characters, hangs on this trope.
** In the very first episode, Ichigo gets stabbed in the heart by Rukia, giving him her full {{Shinigami}} powers. Slightly averted when we are told that [[spoiler: his father was also a Shinigami, and hence Ichigo always had those powers, or at least the potential for them]].
** Played straight when, in an effort to regain his Shinigami status, Ichigo visits Urahara, [[spoiler: who has his Chain of Fate chopped off, and turned him into a Vizard instead... and when this isn't enough to let him defeat Ulquiorra and rescue Orihime from him, he becomes an even MORE powerful hollow...]].
* In ''Manga/OnePiece'', [[{{Cyborg}} Franky]] manages to rebuild ''himself'' after being run over by a train. Of course, this merely serves to make him even more CrazyAwesome.
* In the first episode of ''Manga/{{Hellsing}},'' Seras combines this with FirstEpisodeResurrection. Alucard [[ShootTheHostage shoots through her]], using a gun that fires explosive shells, to kill the vampire holding her hostage. He at least asks her permission before vampirising her, and this is also an exception to "never ends well" since she doesn't turn evil though she has gone on a couple of {{Mook|s}} killing rampages.
** This is because she didn't embrace her new nature. Once she did, she got some of Alucard's quirks, like SlasherSmile, open admission of her status as a monster, trolling Integra and offering her to make her a vampire. Of course, it is what Alucard wanted from the very beginning, so it still counts as positive outcome.
* Happened in ''Anime/{{Nightwalker}}'', vampire variation: [[spoiler: Shidou has to turn his girlfriend and local PluckyOfficeGirl, Riho, into a vampire to save her life.]]
* In ''Anime/TransformersVictory'', a dying God Ginrai is transformed into Victory Leo, a MechaExpansionPack for Star Saber. He goes feral for a bit but eventually snaps out of it. (Since God Ginrai was actually a CombiningMecha formed of Super Ginrai and Godbomber, the inability to separate might have been a factor in the trauma.)
* In ''Manga/TsubasaReservoirChronicle'', [[spoiler: Fai almost dies from shock caused by the loss of an eye. He is saved by being turned into a vampire who can only feed from one specific person (Kurogane)]].
* ''Manga/FrankenFran''. Fran's ideal is the preservation of life by all means possible, without much regard for the patient's opinion and a quite elastic definition of 'life'. BodyHorror ensues, though surprising enough some of her patients still get a HappyEnding.
* The story of how Fate and Arf met in ''Anime/MagicalGirlLyricalNanoha'' as revealed in the [[AudioAdaptation second Sound Stage]] of the first season. Fate finds a dying wolf, and to save her, she turns the wolf into her {{familiar}}.
* This is how Hiro ended up WakingUpAtTheMorgue in ''Manga/PrincessResurrection'', the titular Monster Princess's RobotGirl accidentally ran him over, so Hime made him her servant with her blood/life essence, incidentally saving his life and making him {{Nigh Invulnerab|ility}}le. Likewise this is done for a Mermaid who had given up her voice. She broke the taboo by shouting to save them which resulting in a death curse; and a different member of the Monster Royalty gave his blood/life essence to her.
* ''VisualNovel/ShinkyokuSoukaiPolyphonica'' has Prinesca Yugiri. After a fatal injury, her father's spirit combined with her, effectively making Prinesca more than human. The most noticeable sign of the change was her blonde hair turning to purple.
* A less serious example would be Hazumu's transformation into a girl in ''Manga/KashimashiGirlMeetsGirl''. His male body was crushed after getting hit by a spaceship, and for whatever reason they rebuilt him as a female.
** The strong hints that Hazumu was actually a girl suffering from Gender Identity Disorder may or may not have had something to do with this decision.
* Rather sad example in ''Manga/DGrayMan''. How so? Well Allen Walker out of his sadness at his adopted father's death accidentally has him transformed by the Millennium Earl ''post-mortem'', turning him into the skeleton for a human-killing machine. Said skeleton then curses Allen's left eye, before being torn to shreds by the [[TykeBomb kid's newly awoken powers]].
* ''Manga/SazanEyes'' starts with the main character, Yakumo, killed by a pet monster belonging to the last Sanjiyan (Pai). Pai saves him by taking his soul into herself, turning him into a Wu, an immortal being whose mission is to protect the Sanjiyan (if the Sanjiyan is killed, he dies). The Wu still looks human and is free-willed, but becoming one makes him a severe PlotMagnet and he must leave his friends and travel with Pai until they can become human.
* In ''Manga/RosarioToVampire'', [[spoiler: Tsukune]] gets repeated emergency transformations anytime Inner Moka isn't able to fight. Then the last attempt at an emergency transformation turned [[spoiler: Tsukune into a [[WithGreatPowerComesGreatInsanity crazy powerful]] ghoul.]] Oops! [[spoiler:It takes a succession of holy artifacts, TrainingFromHell and even more extensive transformations to let him control his power..]]
* In ''Manga/TheLaughingVampire'' by Creator/SuehiroMaruo, as the girl Luna is strangled and LeftForDead on a rubbish heap, the protagonist, a teenage male vampire, transforms her -- a beautiful scene with fireworks going on in the distance.
* There's an entire ''race'' of humans who have undergone the Emergency Transformation in the works of Leiji Masumodo, "The Machine People." Machine People can be arrogant and cruel, but they can also be wise and sad. How much of your soul cybernetics eats depends on the person and story in question.
* In ''VideoGame/MonsterRancher'', monsters can be combined to make a new, stronger monster. [[Anime/MonsterRancher The anime]] [[PlayedForDrama played this for drama]] by having [[spoiler: Big Blue]] [[HeroicSacrifice volunteer to be combined with]] [[spoiler: Pixie]], giving up their own life to save [[spoiler: hers]].
* In ''Anime/CodeGeass'', [[spoiler: [[EnsembleDarkhorse Jeremiah]]]] gets hit with it TWICE. First he's rebuilt after apparently being killed by [[FacePalmOfDoom Kallen]], coming back in the first season finale with a major screw loose and angst about being mechanized. [[spoiler: After being crushed in his mecha by water pressure at the end of the season,]] he returns again in season 2, upgraded further, with his sanity intact and no longer concerned with his transformation. Then he has a [[spoiler: HeelFaceTurn and becomes even more of a MemeticBadass]].
* A common practice in ''Franchise/GhostInTheShell'' in its various incarnations, with cybernetics being used for repairs or wholesale replacements of the body. [[spoiler: Motoko was stated to have been one of the earliest humans saved using a full prosthetic body in this way, after she and Kuze survived a plane crash as children.]]
* Aureolus Izzard attempted to turn Index into a vampire in ''LightNovel/ACertainMagicalIndex'' in order to stop Necessarius from inflicting the [[spoiler:periodic memory loss]] on her. However, he didn't know that Touma had already saved Index from her fate.
* In ''Manga/BlackBloodBrothers'', this happened to Jiro Mochizuki, when he was turned into a vampire by Alice Eve, prior to the start of the series.
* In ''Anime/ArmitageIII'', Ross has an artificial leg at the beginning. Later in the story more than half of his body is replaced with mechanical parts to save his life.
* In ''Manga/DragonBall'' and ''Anime/DragonBallZ'', [[PsychoForHire Tao Pai Pai]], [[MadScientist Doctor Gero]], and [[BigBad Freeza]] go through this, with varying degrees of success. While Tao Pai Pai and Freeza [[TheWorfEffect are quickly defeated to show how powerful certain protagonists are or have become]], Doctor Gero lasts longer before [[HoistByHisOwnPetard he's killed by his own androids]].
* In ''Literature/MardockScramble'', protagonist Rune Balot, a DisposableSexWorker, is almost killed by her current boyfriend/employer in a car bomb. Dr. Easter intervenes and saves Balot's life by turning her into a technopathic cyborg. Though he was unable to save her vocal chords, so she is now effectively mute when not controlling speaker systems.
* Played with in ''Manga/DailyLifeWithMonsterGirl''. [[spoiler:[[TheGrimReaper Lala]] turns a dying a girl into a zombie in chapter 38. Not to prevent her death, but so she won't have to, since the girl will come back to life afterwards.]]
* Dio Brando used the Stone Mask to become a vampire in ''Manga/JoJosBizarreAdventure'' Part I when Jonathan and the police had him cornered after exposing his attempts to murder George Joestar.
* ''Manga/UQHolder'' uses this as the basis of the plot: the protagonist inadvertently gets himself in the way of a bounty hunter who cuts off his arm and impales him, and his only means of survival is to drink [[Manga/MahouSenseiNegima Evangeline's]] blood to make himself immortal.
* The plot of ''Manga/TokyoGhoul'' begins with one of these. After being critically injured in a Ghoul attack, Kaneki wakes up in the hospital to learn that he's received an organ transplant from his attacker. Soon enough, he becomes unable to eat normal food and begins noticing strange [[HorrorHunger urges]] and realizes the surgery turned him into a HalfHumanHybrid. [[spoiler: When he finally confronts MadScientist Dr. Kanou about turning him into a Ghoul, the doctor justifies it by claiming that either way, doing so saved his life]].
* In ''LightNovel/HighschoolDxD'', this is how another being's transformation into an angel or devil generally works, Issei being the primary series example. It does not need to be done to save someone from death, but it can if necessary.
** [[spoiler: Later in the series, this happens to Issei again. He is mortally poisoned, and so his consciousness/soul is transferred to his Sacred Gear (which is locked in armor form) while Ophis and Great Red create him a new body. He looks the same in the end, but his new body is more Dragon than Human (until he gets converted to a Devil again).]]
* In ''LightNovel/SorcererStabberOrphen'', according to Orphen himself, this happened to [[spoiler: his once partner and the local CoolBigSis Stephanie.]] [[spoiler: She was a [[TransSexual male-bodied sorceress]] whose body was torn apart in a terrible accident and had to be reconstructed from almost zero by the local healers. Right before that she explained her case to them, asked if she could be given a female body and they accepted.]]

[[folder:Comic Books]]
* This is how Patriot from ''Comicbook/YoungAvengers'' said he got his powers, via blood transfusion from his super-grandpa. [[spoiler: He was lying.]] And then later [[spoiler: it happens for real]].
* [[Comicbook/SheHulk Jennifer Walters]], attorney at law, also got a blood transfusion - from her cousin [[Comicbook/IncredibleHulk Dr. Bruce Banner]]. Unusually for this trope, Jen usually likes being Comicbook/SheHulk or even prefers it to her human form. The later {{Retcon}} that the Hulk's personalities are a result of multiple personality disorder and were not caused by his powers happens to explain away why she doesn't have the same problems the Hulk has. Of course, she did have some issues at first (but more roid rage-ish than "HULK SMASH"). As she became more used to the transformation, her lack of inhibitions shifted themselves from wanting to break stuff to just having fun.
* The ''[[Comicbook/TeenTitans New Teen Titans]]''
** ComicBook/{{Cyborg}} was given his cybernetic parts by his father after an attack by an other-dimensional creature nearly killed him, ate his mother [[spoiler: and fatally contaminated his father with radiation poisoning (which neither knew about at the time)]]. It took the traumatised Cyborg quite the time to come to terms with the whole deal, understandably.
** Gar "Beast Boy" Logan gained his powers when his parents injected him with an experimental serum to save him from a rare, incurable disease.
* ''Comicbook/DoomPatrol'' (Gar's former team), could be poster children for this - especially Robotman and the original Negative Man! Niles "The Chief" Caulder arguably counts (defusing a bomb implanted in his chest put him in a wheelchair), but with current continuity turning him into a monster that [[MagnificentBastard arranged the horrific accidents that changed some members of Doom Patrol]] into "heroic freaks."
* ComicBook/{{Steel}}/Commander Steel of DC - Henry Heywood was severely injured by saboteurs. A scientist gave him steel replacement parts, saving his life and turning him into a super-strong and durable "indestructible man". In the Comicbook/{{New 52}} ''"Rotworld"'' stories Henry Heywood uploaded himself into a robot body when the Rot was taking over the bodies of the living.
* Creator/{{Marvel|Comics}}: A blood transfusion from the original ([[RidiculouslyHumanRobots highly humanlike android]]) Human Torch gave Spitfire her super-speed powers. Yes, a ''blood transfusion'' from a ''flaming robot'' gave her ''super-speed'' powers. A second transfusion forty years later not only reactivated her then-faded powers, but ''de-aged her back to the age when she first became Spitfire.''
* In the ''Comicbook/ForgottenRealms'' comics, the character Minder was originally a dwarven adventurer who was fatally injured in battle; in desperation, the wizard of the group transferred her spirit into a magically animated golem.
* ''[[Comicbook/{{Legacy}} Star Wars: Legacy]]'': Cade refuses to let his childhood love Azlyn die, even though she ''asks him to'', accepting her fate and the will of the Force. When all other options fail, he gets her to people who put her in a Vader-esque life support armor. After waking up, she was ''really pissed at him''. Fortunately for her, she managed to avoid slipping to the Dark Side and managed to get the scary black suit replaced with something much more elegant.
* Bunnie Rabbot in the ''[[Comicbook/ArchieComicsSonicTheHedgehog Sonic the Hedgehog]]'' comics had already been changed into a cyborg against her free will; however, being only half-roboticized, the effects eventually catch up with her and start screwing up her body, putting her in the hospital. She's given the option of removing her original robotic limbs (transformed from her real ones) and replacing them with new ones (which would ruin her chances of deroboticization and having her original flesh-and-blood body back, a longtime goal/dream), or trying to treat her condition to slow oncoming death. She goes for the upgrade, deciding to finally fully accept herself as a cyborg. [[TakeAThirdOption There was another option that they could have tried]], but knew it was way too risky - attempting to deroboticize her. The problem was that they didn't exactly have the original roboticizer - they had it, but Sonic damaged it when they rescued her way back when and they ended up rebuilding it to use later on. As it wasn't the original one, using it to revert her to normal would be life threatening.
* When Techno of the ComicBook/{{Thunderbolts}} got his neck snapped, he transferred his consciousness into his pack o' gear, forming a robotic body out of it. He liked it much better than his human body.
* In ''Comicbook/ThirtyDaysOfNight'' [[spoiler:Eben Oleman injects himself with vampire blood in order to save the remaining survivors of Barrow]].
* The [[Franchise/StarWarsExpandedUniverse Biggs Darklighter]] comics have [[Comicbook/XWingSeries Hobbie Klivian]] repeatedly lose limbs and need prosthetics to keep being a pilot. [[http://img142.imageshack.us/img142/4452/blz05.jpg One of Biggs' lines]], while commenting on the strength of a prosthetic hand, is "Not like it makes up for losing your..." ...which is generally taken to mean that Hobbie lost his penis.
* Inverted in an early ComicBook/SpiderMan comic: When Peter Parker had to make a blood transfusion to save Aunt May, he was almost completely depowered for about a week while the villains-of-the-issue ran amok. [[TheyWastedAPerfectlyGoodPlot Aunt May didn't get any of his powers, either]] - in fact, the [[ILoveNuclearPower radioactivity in his blood]] later caused her ''further'' health problems during the Master Planner storyline.
* The Machinesmith, as recounted at the top of the page. A little later in the issue, while he is attacking with a [[MesACrowd crowd of duplicates]], Comicbook/CaptainAmerica reasons that only one of them must hold the original's mind and the others must be directed by a computer bank that they are defending. He damages it, and all the robots fall. The sparking computer tells him that yes, his robots did program-record his mind, but into this computer; to get mobility he "microbeamed" into the bodies and he's never quite all there, so no matter how [[RidiculouslyHumanRobots human-looking]] the bodies he built were, he was living a lie. And [[ICannotSelfTerminate he couldn't self-terminate]], so he thanks Cap for falling for his plan and helping him commit suicide. Though given some of the events before this, it's entirely possible that he was [[ILied lying]]; his "death" here was the kind that is conveniently easy to undo in case the writers wanted him back. And in fact he was, as an {{Energy Being|s}} able to transfer into ''any'' electrical device.
* Also happened to the ComicBook/RedSkull, who transferred his consciousness into the body of one of Arnim Zola's robots.
* After going a few rounds with {{ComicBook/Daken}} in ''ComicBook/DarkReign'', Comicbook/ThePunisher was dead, until ComicBook/{{Morbius}} the Living Vampire glued him back as a Frankenstein's-Monster like being (Franken-Castle).
* In the AlternateUniverse series ''Mutant X'', Gambit was turned by a Storm that didn't "get over" Dracula's bite back when. It almost costs both their unlives.
* In ''Franchise/{{Superman}}'', Hank Henshaw's physical body expired due to radiation exposure, but is able to transfer his consciousness into a robot body. His wife killed herself after seeing his new body and the Cyborg Superman later became a DeathSeeker.
* ''Comicbook/{{Planetary}}'' #0's story of a Wildstorm analogue to Comicbook/IncredibleHulk incorporates this. Here, rather than a gamma bomb, ersatz-Banner was caught in the blast of a {{Reality Warp|er}}ing supercomputer, which he had set to erase from the universe all matter within a small area of desert. A witness to his transformation into a {{Nigh Invulnerab|ility}}le monster hypothesizes that in order to turn himself into something that would survive the blast, ersatz-Banner ran through his head an [[FormulaicMagic equation]] based on the theoretical physics behind the computer's Reality Warping.
* In ''[[Creator/MilestoneComics Xombi]]'', inventor David Kim was revived from a critical wound when his lab assistant injected him with a [[HealingFactor beneficial]] [[{{Nanomachines}} nanotechnological virus]]. In order to rebuild David, his nanites used the closest matter available, which included ''the lab assistant herself''.
* The short-lived Franchise/ArchieComics title ''ComicBook/ManTech'' (based on a line of toys) was about a trio of dying astronauts who are found by an alien. The alien saves their lives by turning them into super-powered cyborgs. Lasertech loves the change, Solartech accepts it as necessary, and Aquatech hates it.
* In ''Comicbook/HackSlash'': ''Slice Hard'', Emily Cristy's cosmetics company researched [[RevenantZombie "slashers"]] in hopes of reversing the aging process; when the slashers escape, "slasher serum", which induces the transformation into a slasher upon death, is the only thing to come of this research. Cristy used a vial on herself after being mortally wounded by an escaped slasher. This had the side-effect of making her go absolutely crazy -- they don't call them "slashers" for nothing.
* This is the origin of the Human/Atomic Sub in ''Big Bang Comics''. The aged Dr. Noah Talbot designed a sophisticated robot body as a prosthesis for injured soldiers, but when Nazis came to steal his research he suffered a heart attack and was forced to transfer his own mind into his creation before he died. It wasn't a decision he would regret, even though an oversight in developing the body's artificial "blood" meant it had to be submerged in water once every hour or so.
* In ''ComicBook/SupermanAndBatmanGenerations'', Superman destroys the Ultra-Humanite's escape rocket, which critically injures Ultra's body and damages his minion "[[ComicBook/LexLuthor Ell]]"'s brain. Ultra's robot minions put his brain in Ell's body, and he spends the next fifty years posing as Lex Luthor in his quest to get revenge on the Man of Steel[[note]]This may be author Creator/JohnByrne [[LampshadeHanging lampshading]] the similarities between the two characters during UsefulNotes/TheGoldenAgeOfComicBooks[[/note]]. In the meantime, the robots attempt to heal Luthor's damaged brain and rehabilitate his evil personality, which results in his becoming the story's version of Metallo.
* In ''ComicBook/DeathVigil'':
** Clara was the target of HumanSacrifice for her {{Necromancer}} boyfriend's RitualMagic. To seal away the monsters summoned and prevent her from dying, [[DontFearTheReaper Bernie]] offers to make Clara into one of the Vigil's members. Clara accepts under the pretense of "not dying".
** Allistor cures Mia's SoapOperaDisease by sacrificing and binding her to a [[EldritchAbomination True Primordial]], which makes her immortal at the cost of developing a HorrorHunger and loss of humanity (at least, until she meets James).
* In one alternate reality where the ComicBook/{{Runaways}} were recruited to form the ComicBook/YoungAvengers, Chase became the new Iron Lad after getting stabbed in the chest. The Iron Lad chestplate happened to be nearby, and it was capable of dispensing nanites to heal wounds, so he grabbed it and stuck it on. His teammates all suggested that he'd probably never be able to remove the chestplate without dying.

[[folder:Fan Works]]
* Protocol Cy-Fox hinges on this. When Tails is brutalized by the [[CyberneticsEatYourSoul Cybernetics Eat Your Soul]] suffering Metal Sonic Mark V while defending the ARK from attack, he finds himself forced into a cyborg form by none other than Maria Robotnik (with a M.D. now).
* ''FanFic/TheReturn'' is built on this. There are precisely two Succubae who were transformed without it being this trope, and only one of those went into it fully informed of the consequences.
* John in ''Fanfic/WithStringsAttached''. He's hit with metamorph powder, which if left unchecked would [[BalefulPolymorph mutate him horribly]]. The Fans can't neutralize it, but they can direct it into a more palatable form. After discovering he's [[WingedHumanoid grown wings]] (among other changes), he has a WhatHaveIBecome moment for about half a day. After he throws himself over a cliff and flies, though, he's a lot happier with his new body. (Though later he finds he's been BlessedWithSuck, but it's not a big problem until the possibility of going home arises.)
* There are a couple fics out there based on the ''Manga/RanmaOneHalf'' manga only Herb Arc goes badly for Ranma, requiring one of these, such as Relatively Absent (Anime/SailorMoon crossover in which Ranma's chosen to replace Setsuna as Sailor Pluto post Season S to keep Ranma alive after being buried in a landslide caused by the fight with Herb), or [[http://www.fanfiction.net/s/3802756/1/The_Weapon The Weapon]], which has an organization rebuilding Ranma after the fight.
* ''FanFic/ThePowersOfHarmony'' has this as an important event in the backstory: [[spoiler: When [[GreaterScopeVillain Discord]] mortally wounded her, [[BigGood Harmony]] fused herself with the planet to stop him from killing her. Unfortunately, that's left her [[SealedGoodInACan trapped]] ever since]].
** When the Changeling Princesses Cocoon and Pupa, and Pupa's pegasus friend Pilgrim were all mortally wounded in a cave-in, Cocoon's last act was to [[FusionDance fuse Pupa and Pilgrim together]], saving both their lives in the process.
* ''FanFic/TheAlteredFateOfDracoScales'' has this happen in the backstory to Nightshade, wherein she was sent through a mirror to the FisherKingdom Equestria. Despite this, [[AngstWhatAngst She's quite accepting of it]].
* The ''Fanfic/PonyPOVSeriesChaosVerse'' version of Fluttercruel was severely injured while in Oblivion, forcing Discord to infuse her with chaos to save her. As a result, she becomes a [[HalfHumanHybrid Half Pony Hybrid]] with similar powers to him.
* In ''FanFic/DiariesOfAMadman'', Celestia and Luna have to infuse Navarone with the life force taken from a tree in order to heal his major injuries. As a result [[{{Transflormation}} he gains several plant-like characteristics]], as well as much increased life expectancy.
* Near the end of ''FanFic/NeverHadAFriendLikeMe'', this happens due to MayflyDecemberFriendship leading towards the inevitable conclusion. [[spoiler:To prevent them from dying of old age, [[JerkassGenie Norm]] ends up turning [[OriginalCharacter Amanda]] and [[WesternAnimation/TheFairlyOddParents Timmy]] into a genie and fairy respectively.]]
* In ''Fanfic/XCOMRWBYWithin'', during the events of the [[WhamEpisode Site Recon mission]], [[spoiler: Blake]] is badly wounded, and has to be turned into a [[Main/{{Cyborg}} MEC Trooper]] in order to survive.
* ''FanFic/ResidentProject:'' When she learns that the T-virus is loose, Annette injects herself and her daughter with the shinigami vaccine. She becomes a yuurei, while Sherry becomes a full shinigami.

* Disney's ''Film/InspectorGadget'': ditzy security guard John Brown is "rebuilt" as a cybernetic super cop after running afoul of Sanford Scolex/Claw. This results in a brief moment of WhatHaveIBecome when Brown sputters "I'm not me anymore! I'm a hardware store!" Apparently happened to the original WesternAnimation/InspectorGadget...only he'd just fallen down the stairs! From a banana peel, no less.
* ''Film/PiratesOfTheCaribbeanAtWorldsEnd'' has this happen to [[spoiler:Will]] when [[spoiler:Jack]] sacrifices his chance at immortality to save him from being mortally wounded.
* The film [[InNameOnly named]] ''Film/IRobot'' had this happen with cybernetics to Lt. Spooner, combining WhatMeasureIsANonHuman, SurvivorGuilt, and [[FantasticRacism robophobia]].
* ''Franchise/StarWars'': Calling [[EvilMentor Palpatine]] an ally would be quite a stretch, but Anakin returns from his duel with Obi-Wan so badly injured in ''Film/RevengeOfTheSith'' that he's given robotic limbs, a ton of robotic organs, and a pressurized life-support suit to create Darth Vader. Obi-Wan was being ''very literal'' when he said "he's more machine now than man." Due to the emergency nature of this transformation, Vader ends up with a body that's [[MightyGlacier physically powerful but far less agile than he'd been while fully human]]. Other characters, not being quite as badly injured, get ArtificialLimbs.
* ''Film/{{Doom}}'' has the main character injected with the [[GreenRocks superhuman and/or demon serum]] after being fatally injured in a textbook example. The treatment he took theoretically has no disadvantages associated with it, however it does run the risk of getting oneself [[spoiler: transformed into a vicious, murderous mutant creature]]. Part of the explanation was that [[spoiler: the "demons" themselves instinctively only tried to infect those with the "evil gene" or potential for evil or whatever, which is what made them monsters due to the virus/serum. So in theory, any person that the demons didn't purposely infect to turn into monsters would develop super-powers instead]].
* This is the origin story for ''Franchise/{{RoboCop}}''. Shot, run over and brutalized by drug dealers [[Film/RoboCop1987 in his 1987 debut]], Officer Murphy would have died from his injuries... ''should'' have died from his injuries... if it weren't for the Detroit Police Department having a deal with [[MegaCorp OCP]], who as part of a drive to manufacture a police force capable of dealing with the rampant crime decided WeCanRebuildHim. The result? Only parts of his upper torso are still organic, part of his brain has been replaced with computers, and he has problems feeling and even recovering his free will. One amazingly cruel scene has one of the doctors mention they could save one of his arms, but the CorruptCorporateExecutive blithely orders it lopped off (although there is FridgeBrilliance here: leaving the biological arm on would mean a lot more meatware to have to support on the damaged digestive system, would have resulted in imbalanced strength and maintenance-one arm has a titanium grip and can be upgraded with a trip to the machine shop, the other doesn't and must be exercised, not just repaired-and would have looked even creepier due to the lack of symmetry). Amazingly, his [[TheFettered dedication to duty]] allowed him to [[WhatHaveIBecome survive the change]], [[CyberneticsEatYourSoul recover his humanity]] and make impressive crime busts, even managing a ZerothLawRebellion with a little help from an OCP executive.
* Happens in the prologue to ''Film/{{Dragonheart}}'', in order to save a dying prince.
* In ''Film/{{Underworld}}'', this trope is played straight in an unusual format: [[spoiler: Selene bites Michael to save his life. Strange in that Michael was already a werewolf, and he was dying from being shot by silver bullets. The bite then turns him into a werewolf/vampire hybrid]].
* Subverted in ''Film/{{Avatar}}'': [[spoiler: When Dr. Augustine is mortally wounded after being shot, she and her avatar are brought to the Tree of Souls with the purpose of transferring her consciousness permanently into her avatar. However, the transition fails as her human body is too gravely wounded. It does, however, succeed with Jake at the end of the film]].
** [[spoiler: Unfortunately not a subversion of NoBiochemicalBarriers]].
* In ''Film/{{Thirst}}'', accidental vampire Sang-hyeon makes a last-minute decision to save his human lover Tae-ju by this means. [[AlwaysNeedWhatYouGaveUp At first]], this seems [[ILoveYouVampireSon pretty positive]]. [[IHateYouVampireDad At first]]...
* ''Film/NearDark'' features a variation in which Caleb is cured of vampirism by means of a total blood transfusion, although it was more of a long term solution than an emergency gambit.
* ''Film/TheAnimal'' explores the [[SarcasmMode serious ramifications]] of a near dead man having his organs replaced with those of various animals.
* Why Caster was uploaded into a computer in the first place in ''Film/{{Transcendence}}''.
* ''Film/DarkShadows'': Barnabas Collins bites [[spoiler: Victoria and transforms her into a vampire to save her from a fall off the cliff at the end]].

* ''Literature/{{Twilight}}'': [[spoiler: Edward turns Bella into a vampire after she almost dies from childbirth. They always planned to transform her eventually when they married, but her SurprisePregnancy ultimately drove those plans]]. This goes for the others as well, since Carlisle only ever changed people who would have otherwise died for sure, [[WhoWantsToLiveForever because he didn't want to condemn anyone to his immortal existence]].
** Also, Alice was transformed to save her from a hunter-vampire, and Esme was changed after an [[InterruptedSuicide almost-successful suicide attempt]] after losing her only son. Carlisle and Jasper however, were not.
** This also happened to Edward. In 1918, at age 16, [[IllBoy he]] and his mother were dying from the Spanish flu. She took him to Carlisle, begged him to save Edward ''at any cost'', then died.
* In ''Literature/TheTwoPrincessesOfBamarre'' by Gail Carson Levine, [[spoiler: the cure comes too late for Meryl, who has to be turned into a fairy]], and it turns out [[spoiler: this is also what happened to legendary epic hero Drualt]].
* Happens in Creator/AnneRice's novel ''[[Literature/TheVampireChronicles Queen of the Damned]]'' with a female character.
** Not only Jesse received this. Even though Marius had planned to make Armand a vampire anyway, he didn't want to bring him over as early has he had to when Armand was about to die from a stab wound with a poisoned blade.
** And in ''The Vampire Lestat'', Lestat's first vampire offspring was his mother, to save her from death by tuberculosis. She more-or-less gave her consent beforehand and, arguably, took to vampirism better than Lestat.
** Subverted in a manner with Claudia in ''Interview with a Vampire.'' Wracked with guilt over his own recent transformation, Louis is wandering the backstreets alone when he finds a little girl who has just been made an orphan by the plague. Desperate with hunger, and thinking he can perhaps grant her the mercy of a quick death rather than catching the plague or starving to death on her own, he feeds and takes her to the brink of death. Lestat then pops in and, deciding it would be fun to have an eternal vampire daughter (not to mention something/someone to help bind Louis to him), he turns her. Louis spends years (if not decades) blaming himself for taking her mortal life, and while Claudia forgives him (she sees vampires as predators and thus has no moral problem with him having killed a human girl), she comes to hate her other "father" Lestat for making her an eternal child.
* ''Literature/TheSookieStackhouseMysteries''
** [[Series/TrueBlood Sookie Stackhouse]] is given Vampire blood to save her life rather than to bring her all the way over to the vampire side. In fact, drinking Vampire blood is a drug addiction thing in this/these series, because it enhances humans temporarily.
** Bubba, aka [[spoiler:Elvis Presley]] was vamped in a hurry to save his life. It [[CameBackWrong was not precisely a success]].
* In the ''Literature/BloodBooks'' series, [[spoiler: this happens to Vicki. Not in the show, though]].
* Interestingly, this is averted sort of in ''Literature/AnnoDracula'' by Creator/KimNewman -- there's descriptions of vampirized people who had syphilis in life still showing the symptoms and, oddly, tubercular vampires still coughing blood.
** The same novel has a scene where Genevieve attempts to perform this on a friend who has been fatally wounded in an attack, but the friend chooses to die rather than become a vampire.
* In Creator/FredSaberhagen's ''Literature/TheDraculaTape'', Dracula turns Lucy Westenra to save her from death ''at the hands of Dr. Van Helsing'', who's been stubbornly giving her blood transfusions in ignorance of blood types.
* In LJ Smith's novel ''[[Literature/NightWorld Secret Vampire]]'', Poppy is diagnosed with pancreatic cancer, which is rare, painful, and inoperable in her case. Her options are death and vampirism. Her childhood friend James does the honors.
* There's a scene in one of Creator/MercedesLackey's ''Literature/HeraldsOfValdemar'' books that would qualify, where a woman (a disembodied soul trapped in the body of a bird, actually) is transformed into a spirit being rather than fade away in the bird's mind. In addition, the Sword Need is [[spoiler: revealed to have been created when the blacksmith forging the sword's village was attacked. She impaled herself on the blade that was in the vice, and awoke inside the sword. Eventually set free during a HeroicSacrifice]].
* All of science fiction author Creator/JackChalker's works seem obsessed with transformation and body swapping, and this kind of "rescue" appears in more than a few, with the ur-example being Nathan Brazil's soul transference from his dying body into a deer-like creature in ''Literature/MidnightAtTheWellOfSouls''.
* Subverted in the ''Literature/BetsyTheVampireQueen'' series: Jessica, Betsy's closest friend, is suffering from severe blood cancer. She makes it very clear to Betsy that under ''no'' circumstances is Betsy to vampirize her. [[spoiler:The cancer is eventually cured via [[DeusExMachina Deus Ex Ancient Vampire Power]].]] Same thing happens with [[Literature/KittyNorville Kitty Norville's mother and her cancer]]- she declines getting werewolfed as a cure. Her health status is still in question.
* Creator/CLMoore's classic story ''No Woman Born'' concerns an actress whose brain was transplanted into a robot body after her body was irreparably damaged in a fire.
* The main character of Creator/PeterDickinson's ''Eva'' gets in a terrible car crash and wakes up in the body of a ''[[EverythingsBetterWithMonkeys chimpanzee]]''. A bit of a subversion, because she actually adjusts to her new life quickly after the initial shock. She eventually chooses to live out her life in the wilds with more conventional chimps.
* A variation in ''Literature/TheLastUnicorn'': Schmendrick decides the only way to save the Unicorn from the Red Bull is to change her into some other creature. Then the Bull will have no interest in her. Thanks to the random effects of his magic, he winds up changing her into [[HumanityEnsues a human]] - and she does '''not''' react well.
* Inversed in the vampire romance novels of Kerrelyn Sparks, here [[spoiler: reacts a character astonishingly well to her new vampire form, although she hates vampires with a passion and no-one else believes her that she is fine with the way she is now]].
* Kerrelyn Sparks ''Love at Stake'' series also contains Gregory, a youthful vampire who was emergency turned by the [[FriendlyNeighborhoodVampire main protagonist]] of the first novel. His own mother, now an elderly personal assistant to the main protagonist, even begged that he would be saved - thus creating the first vampire that never had to bite someone to survive.
** later, another (side-)character is emergency turned but thinks it is awesome, because he's got superpowers now.
* Inverted in ''Literature/{{Xenocide}}'': as the setting's version of the Internet is brought down, it threatens to bring the artificial intelligence Jane along with it. The only way she can survive is [[HumanityEnsues by taking a human body]]... and afterward, even though it's possible, she doesn't ''want'' to go back to being what she was before.
* Happens to the antagonist character, Skade, early in ''[[Literature/RevelationSpaceSeries Redemption Ark]]'', who [[spoiler: gets her body sheared in two. Unwilling to give up, she has her head cut off and attached to a life support system that she can plug into a robot body]].
** She chooses this over getting a nice new human body because she is impatient, desirous of being more resilient to the harsh conditions on her ship, and a little bit... differently sane. It also helps that it makes her extra scary. She gets a new organic body before the sequel ''Absolution Gap'' occurs, though for other practical reasons.
* Happens all the time in ''Literature/{{Animorphs}}'', since there, transformation is ([[ShapeshifterModeLock usually]]) temporary and completely rebuilds your body, both to and from a given form. And the Animorphs find themselves in plenty of life-threatening situations.
** In this case "All the time" means several times per person per scene in the later books.
* In the Franchise/StarWarsExpandedUniverse, this happens to Jedi Callista Masana ''twice''. Once when she's dying and transfers her consciousness to a ship's computer in order to continue her mission, and then again 30 years later when the ship is about to self-destruct and Jedi Cray Mingla--who is suicidal--offers her body so Callista can escape the computer. The first time is just better than death, but when she loses all contact with the Force after the second transfer, there is much angst.
** Also subverted in the same book 'Children of the Jedi'. Cray's lover and fellow Jedi Nichos Marr contracted a fatal disease and Cray attempted to transfer his consciousness into a droid body using alien technology. However, the result was merely a droid programmed with Marr's personality.
* [[http://starwars.wikia.com/wiki/Ton_Phanan Phanan]] of the Comicbook/XWingSeries. While he's a funny DeadpanSnarker, ''wow'' do [[StepfordSmiler things get tragic]] after Face finds him drinking and complaining that it's easier to get drunk. Every year, less meat, more machine.
-->"A long time ago, back at the Battle of Endor, the frigate I was working on as a doctor was hit by an Imperial barrage. Blew out whole sections of the hull, sucked crewmen out into hard vacuum. I was hit by a falling beam superheated by laser fire. One minute I'm helping a pilot with a concussion, the next minute that pilot's been dead for two weeks and I'm just waking up with a mechanical half a face and a mechanical leg. Ever since then, no woman has looked at me with any sort of serious interest. [...] Something died when I was hit in that medical ward, and I think it was my future. I think people, maybe only women, can just look at me and say, 'There's no future in him.' [...] There's [[CyberneticsEatYourSoul no mechanical replacement for a future]], Face. And every time I take a hit, and they have to cut away another part of me and replace it with machinery because I'm allergic to bacta, every time that happens I seem to be a little further away from the young doctor who had a future. He can't come back, Face. [[TearJerker/{{Literature}} Not all of him is here anymore]]."
** And then there's [[FromBadToWorse later]].
--> '''Phanan:''' "Starting over means more time. More time for [[BigBad Zsinj]] to bombard more colonies, to destroy more ships. Another day may mean some bright young doctor gets it the way I did and ends up what I am."
--> '''Face:''' "What you are is pretty good."
--> '''Phanan:''' "Not as good as some kid with a superior intellect whose only aim is to make people better. I'd rather he be out there than me."
** And right after that...[[AnyoneCanDie Read the book]].
*** Some other characters also get cybernetics, but they tend to be more along the lines of ArtificialLimbs and sometimes eyes.
* In the ''Literature/MercyThompson'' series, this seems to be the backstory of at least one out of every three supernaturals.
** In ''Moon Called'', Dr. Carter Wallace is dying of cancer, and his son persuades him to undergo the Change to werewolf. His magical new immune system zapped the cancer and made him look thirty or forty years younger. Unfortunately, surviving as a werewolf requires psychologically accepting your new state, which the good doctor is loath to do.
** The backstory of Charles's mother, mentioned in ''Moon Called'' and explained more thoroughly in ''Alpha and Omega'', is that she was dying when a werewolf found her, [[LoveAtFirstSight fell instantly in love]] with her, and Changed her into a werewolf so that she would survive.
** In ''Blood Bound'', Mercy meets vampire Stefan's flock of human blood donors, most of whom are dying of cancer or drug addiction. The longer they donate to a vampire, the more powers they gain and the easier it is to turn them to vampires themselves.
* If a human character in the ''Literature/PerryRhodan'' universe has artificial body parts (up to a [[BrainInAJar full robot body housing the brain]] in at least one case), it's generally for medical reasons. Despite the artificial bits inevitably serving some plot purpose eventually, humans (unlike some alien species) [[NoTranshumanismAllowed don't go for just upgrading their natural bodies on a lark]] even in the distant future.
* This trope is used moderately with in Neil R. Jone's ''Professor Jameson'' stories. The Zoromes, a race of octopus-like aliens, transfer their brains into cyborg bodies when they near death (they also transfer well-preserved brain of the deceased title character). The transformation is portrayed as dulling the emotions, so Zoromes prefer to live a full life before being transferred. Occasionally a younger Zorome is fatally injured, as in the story ''Zora of the Zoromes'' and is transferred early. This is portrayed as very tragic, especially when two Zoromes who were very much in love are transferred prematurely, and then no longer feel anything for each other. On the other hand, the Zoromes don't seem to care if someone wants to transfer early, several aliens do so and join the crew of a Zorome ship in another story.
* In the second ''Literature/EmpireFromTheAshes'' book, [[spoiler:Dahak secretly arranges for his consciousness to reawaken in another starship when his original body is destroyed in a pseudo-HeroicSacrifice, which he wasn't sure would even work]].
* In a less life-or-death example, Sheen the self-willed robot from Creator/PiersAnthony's Literature/ApprenticeAdept novels becomes inert when she crosses over from the scientific world of Proton to the magical world of Phaze. The Brown Adept animates her as a golem, allowing Sheen to function in Phaze.
* Played straight in the ''Literature/{{Otherland}}'' novels by Tad Williams. [[spoiler: Two main characters get their minds uploaded into a hyper-real virtual reality. One was an old man, and the other was [[LittlestCancerPatient a child suffering from a fatal disease]].]]
* In ''Literature/{{Skinned}}'' by Robin Wassermann, the main character Lia gets into a fatal car accident. To save her, her brain is uploaded into the body of an android. This is very rare, but it happens in her future world. These people are shunned because they look [[UncannyValley too perfect]]. The Christian church believes these people are abominations and do not deserve to exist, because they mean science is "creating life".
* In Greg Egan's ''Literature/{{Diaspora}}'', the Earth is about to be hit by the lethal shockwave from a neutron star collision. A pair of [=AIs=] (essentially translated humans) don robot bodies in order to offer last-minute help: let them shoot people with a lump of nanoware that reads their brains while eating them. They can live on as software, escape from the kilos of meat they can no longer protect. What a choice.
* In ''Literature/TheWheelOfTime'' series, Elayne bonds Birgitte as a superhuman Warder after she's ripped out of the dream world. Birgitte doesn't have any obvious physical changes, but the angst is still there--A, because she's been separated from her ReincarnationRomance with Gaidal Cain, and B, because the [[{{Synchronization}} Warder bond]] [[HilarityEnsues turns out to be more effective if you're both the same sex]].
** Later in the series [[spoiler:Gawyn]] needs to be made into a Warder to survive after being wounded, but it's what he wanted anyway.
* In ''Literature/TheApocalypseTroll'' by Creator/DavidWeber, Ludmilla Leonovna, who's effectively immortal via her [[TheSymbiote symbiote-granted]] HealingFactor, [[MayflyDecemberRomance falls in love with a normal human]]. While she could give him her symbiote any time she wants via a simple blood transfusion, this has a 99.99% chance of killing him. When he's mortally wounded and his lifespan is shortened from fifty more years to just five more minutes, though, she decides to risk it. [[spoiler: It works.]]
* A variation in the ''Literature/NightHuntress'' books, when Dave is brought back as a ghoul some time after he died because Cat inadvertently started the process when he was dying and when Bones comes back he helps the team finish it.
* In the ''Literature/NightWatch'' series, the vampire Kostya became that way because he was dying of TB as a child, and so his FriendlyNeighborhoodVampire father cured him by making him a vampire. Similarly, in ''Twilight Watch'', Anton encounters a pack of werewolves and finds out that two of the members are young children who were bitten by the leader, an older guy, to save them from death, and is a loving PapaWolf (pardon the pun) toward them.
** Inverted later, when a friendly werewolf (one of said kids, by the way) takes a magical bullet for Anton while in wolf form. With her last dying breath she transforms back despite his protest that as a wolf she has a better chance to survive, but she prefers to die as a human.
* ''Literature/QuantumGravity'': Lila Black came back from [[OurElvesAreBetter Alfheim]] missing...well, most of her body. She was given the choice to survive or deal with being legless, armless, eyeless...you get the picture. [[WeCanRebuildHim She became a]] {{Cyborg}}.
* In Monica Hughes' ''Keeper Of The Isis Light'' [[spoiler: Guardian makes genetic modifications to Olwen to help her survive the planet's harsh conditions.]]
* In Amy Thompson's ''Literature/TheColorOfDistance'', a scientist crash-lands on an inhospitable alien planet, and the {{Sufficiently Advanced Alien}}s who find her unconscious body transform her into one of them to help her survive.
* In the third book in Literature/TheParasolProtectorate series, ''Blameless'', Biffy undergoes an Emergency Transformation. Unfortunately, [[spoiler: he was the favorite of a vampire who already had plans to [[ILoveYouVampireSon have Biffy turned]], and the only supernatural on hand during the emergency was a [[FurAgainstFang werewolf]]]]. [[IfItsYouItsOkay It's implied the relationship will probably survive, anyway]].
* In Lynsay Sands's Argeneu and Rouge Hunter Series, this is the most common reason for the vampire-like immortals to "turn" others. It is occasionally played for laughs when it turns out that the danger they were "escaping" was all in their heads, though other times it is a serious matter as the turnee is brought near death by some outside force, such as a crazed geek with an axe, or a rival immortal seeking revenge by hurting the one closest to them.
* In ''The Sex Gates'', [[spoiler:Lee, Donna and Russell are forced to push Rita through one of the titular gates after she is stabbed, saving her life at the cost of [[GenderBender turning her into a man]]. Lee accidentally falls through as well, turning into a woman. Especially tragic since Rita was pregnant at the time, and unborn babies don't survive the transformation]].
* In Max Barry's ''Literature/MachineMan'', Dr. Charles Neumann goes to sleep [[spoiler:a paraplegic and wakes up a ManInTheMachine]]. While not a *personal* emergency, Better Future needed SOMEONE equipped to [[spoiler:defeat the {{cyborg}} Carl]], who had run amok.
* In ''Literature/TheDresdenFiles'', [[spoiler: Harry accepts the mantle of the Winter Knight because his back was broken]]. This has far-reaching effects, the least of which being that he is now weak to iron and has to obey thresholds and other fey things.
** The Red Court can do this to people. Only for them it's more that they shed their human-esque disguise.
** Some werewolves can do this. (The Alphas can't, they only have a HealingFactor).
* Emily in ''Literature/TheGirlInTheSteelCorset'' by Kady Cross, is forced to turn [[spoiler: Sam]] into a robot, because [[spoiler: he]] died when a machine attacked him.
%% * [[spoiler:Simon]] is turned into a vampire to save him in ''[[Literature/TheMortalInstruments City of Ashes]]''.
* The Tin Woodsman from ''Literature/TheWonderfulWizardOfOz'' got SerialProstheses after a series of axe injuries, until eventually he was made entirely of tin.
* ''Literature/TheSecretsOfTheImmortalNicholasFlamel'' has Joan of Arc getting a blood transfusion from the vampire Scathach. It doesn't turn her into a vampire, but it does make her immortal, which explains what she's doing in a series that takes place in the twenty-first century.
* Siegfried's bird companion in ''[[Literature/TalesOfTheFiveHundredKingdoms The Sleeping Beauty]]'' isn't dying, but gets an emergency (and permanent) transformation into a firebird because it's the only way Siegfried will be able to get through the wall of thorns. Lily is worried that the bird will see this as a BalefulPolymorph, but the bird's delighted.
* It happens three times in the ''Literature/DenOfShadows'' series. First in ''Demon in my View'', [[spoiler: Jessica is turned into a vampire so that Aubrey and Caryn could heal hear more effectively]]. Then [[spoiler: Sarah gets turned into a vampire]] in ''Shattered Mirror''. Finally, in ''Persistence of Memory'', [[spoiler: Sassy puts his blood in Erin's veins to turn her into a hyena shapeshifter]] in order to save her life.
* A number of ''Literature/MetamorKeep'' characters came to Metamor so that the Curse's transformation could cure their terminal illness. Such as Rickkter, who ironically discovered an alternative cure to his disease the day after he finished turning into a raccoon.
* In the backstory for Severian's travelling companion in ''Literature/TheBookOfTheNewSun'' by Creator/GeneWolfe [[spoiler: we find out that Jonas was a highly intelligent robot who could not be repaired and given a human-like body of flesh in order to save him]].
* In ''[[Literature/WingsOfFire Escaping Peril]]'', Peril realizes that [[spoiler:Queen Ruby's earring was put there by Chameleon to make her never be able to win a fight with Queen Scarlet]], but she doesn't realize that [[spoiler:removing it will turn her into a different dragon altogether.]] Transforming into [[spoiler:Tourmaline]] heals her wounds and allows her to [[spoiler:kill Queen Scarlet and win the throne]].
* Subverted ''Literature/TheUnderneath.'' Hawk Man can save himself from Grandmother's venom by transforming into a hawk, but refuses to do so due to not being able to change back and ends up dying.
* A universe (known to fans as the Rejuve Universe) was created by author Lurking Dragon in which technology exists for rejuvenating people to children aged e.g. 5 or 6. The newly rejuved people are the same people as the pre-rejuved old people, retaining their memories and knowledge, but acquiring the emotions of a child. While primarily used as legal punishment (criminals are rejuvenated back to children where they are raised by a new set of parents - sometimes several times - and have no power of their own), it is sometimes used in an emergency to save the life of a severely injured or sick person.
* In the novel ''I Shall Fear No Evil'', by Robert Heinlein, the main character, Johann Sebastian Bach Smith, who is very old, is given a new life as a young woman by having his brain transplanted into the body of a beautiful young lady, who had been his secretary before she was murdered.

[[folder:Live-Action TV]]
* Pam agrees to do this for [[spoiler:Tara]] in ''Series/TrueBlood''.
* In the distant BackStory of ''Series/BuffyTheVampireSlayer'', the Master did this for Darla as she lay dying of syphilis. Then on ''Series/{{Angel}}'', a human-again but still dying Darla tries to get Angel and other vampires to turn her again.
** Later but still in the BackStory, Angel is stuck on a submarine and the only person who knows how to repair it is fatally stabbed by an escaped Nazi prisoner, so Angel makes him into a vampire.
** Also, [[spoiler:Cordelia is turned into a part-demon by Skip to avoid her being killed by her visions. However, other than some glowy effects and unusual powers, this doesn't actually manifest itself too much, and she becomes a "higher being" soon afterwards]].
** One could argue that a variation on this happens to Illyria: the gang needs to ''remove'' some of her power before she goes supernova and destroys the whole world. She is, of course, none too pleased when [[spoiler: the procedure works]].
** Also, in the ''Buffy'' episode "[[Recap/BuffyTheVampireSlayerS2E7LieToMe Lie to Me]]," a childhood friend of Buffy's tries to get Spike to turn him before he dies of a brain tumor. [[spoiler: Spike does so, but he's staked by Buffy upon resurrection.]]
** Averted in the Season 7 episode "Get It Done", in which [[spoiler: the Shadow Men attempt to give Buffy the strength to defeat the First by infusing her with the essence of a demon. Buffy emphatically refuses with a WhatTheHellHero, and then soundly kicks all three of their asses]].
** Also Backstory, shortly after Spike is turned, he goes home and turns his mother, as she is dying anyway. It does not go well.
* The BackStory to the ''Series/DoctorWho'' two-parter "Silence in the Library"/"Forest of the Dead" also involves this trope, crossed with BrainUploading.
** Also, Time Lords' regeneration abilities that kick in automatically when they're about to die, though they don't get any more powers by regenerating. At least, not in the televised series (though they do have a lot of energy flowing through them in the early stages, according to "The Christmas Invasion" and "Let's Kill Hitler"); there's a reference in one of the Literature/EighthDoctorAdventures books to Time Lord soldiers who had "force-regenerated themselves until their skins had been covered in black organic blast-proofing".
*** The Literature/EighthDoctorAdventures two-part story ''Interference'' by Lawrence Miles featured a Gallifreyan priest who had been given an extremely early version of regeneration tech. As a result, his future lives included a shapeshifter, a cyborg, a heavily scarred man, a freak with a very large head, a serpent-woman, and a little grey thingy that was apparently wired directly into Time. His thirteenth life was basically an EldritchAbomination [[spoiler: that became a planet's entire ecosphere]].
** [[spoiler:The Saxon Master]] subverts and averts by choosing death over [[spoiler:regenerating and being a prisoner. Of course, he had a plan to get better in a ''different'' way, it turns out.]]
** It also happens in the "Rise of the Cybermen"/"The Age of Steel" two parter when [[spoiler:Mr. Crane destroys Lumic's life support system, and the Cybermen convert Lumic into the Cyber-Leader to save him, ignoring Lumic's demand that they wait till they run out of other options]].
** Another angle is given in the episode "Dalek", where [[spoiler:the namesake wants to die rather than live with human morality]].
** The Twelfth Doctor does this to his companion Clara in "Hell Bent". After Clara is KilledOffForReal, the Doctor uses time travel-related tech to extract Clara out of time the moment before her death. She must someday return to this moment to prevent a universe-destroying paradox, but until that day, her life processes (breathing, heartbeat, aging) are frozen and she is functionally immortal.
* On ''Series/ForeverKnight'', Nick acceded to Natalie's request to vamp her brother when he was fatally shot. It didn't go well.
* In ''Series/{{Chuck}}'', [[spoiler: Sarah uploads the Intersect 2.0]] when she's trapped in a firefight. In the series finale, [[spoiler: Chuck himself re-uploads himself with the Intersect 3.0 in order to disarm a bomb]].
* On ''Series/PowerRangersTimeForce'', this was revealed to be the origin of Frax, [[BigBad Ransik's]] right-hand 'bot. Frax had been Dr. Louis Fericks, a scientist who had temporarily cured Ransik of a poison that was slowly and painfully killing him by administering a serum he had created. Ransik thanked Dr. Fericks for the serum by blowing up his laboratory, seemingly killing him. Fericks survived (barely), and rebuilt himself as a robot, then began his plan to get revenge on Ransik.
** Meanwhile, Mesogog's right hand man Zeltrax was saved by Mesogog himself in this manner.
* In the ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' episode "Life Support," Vedek Bareil is seriously wounded in an assassination attempt while concluding negotiations for a permanent peace treaty with Cardassia. Dr. Bashir keeps him alive using increasingly extreme measures while he talks [[{{Hypocrite}} Kai Winn]] through the finalities, ultimately replacing a large portion of his brain with cybernetic implants. The operation has the effect of removing most of his personality, and he only survives long enough to complete the negotiations.
** This was also part of Dax's TheNthDoctor in the last season. Ezri Tigan was the only un-joined Trill available at the time, so they did an emergency implantation to save the symbiont and [[GoneHorriblyWrong created Ezri Dax]].
* ''Series/StargateSG1'' (of course) had instances of this, when characters stricken with fatal injuries or diseases had the option to become a host to a Tokra symbiote. In one notable occurrence, the character in question was dead set against the idea, but when the illness progressed far enough, they went ahead with it anyway. There was also the option of [[AscendToAHigherPlaneOfExistence ascending to a higher plane of existence]], but not everyone could do that.
* In the Japanese series ''Series/{{Ultraman}}'', the first of the Ultraheroes (and some of the later ones) was created when an alien bonded with a human to save his life.
* Serena from ''Series/HerculesTheLegendaryJourneys'' [[spoiler: dies a DroppedABridgeOnHim sorta death, but a TimeTravel story later sees her return, and near the end, she's wounded, but is turned into a healthy human by Ares... still sad since she was pretty awesome as herself, and was the [[LastOfHisKind last of her kind]], and her relationship with Herc was undone, but at least she survives]].
* Subverted on ''Series/{{Moonlight}}'', of all shows. [[spoiler: Josh is shot, and Beth begs Mick to turn him into a vampire, but Mick refuses, and Josh [[KilledOffForReal dies]]. This weighs on Mick and Beth's relationship for the rest of the series.]]
* Mitchell is faced with this twice in ''Series/{{Being Human|UK}}''. In an early episode, he is confronted with a dying colleague in an alleyway. George begs him to save her. [[spoiler: He does nothing. In the next scene, when George is asked "Why didn't he save her?", he replies "I think he did."]] In a later ep, he does this for an injured boy.
* The ''Franchise/KamenRider'' franchise does this a few times in the Showa era with Series/KamenRiderV3, Series/KamenRiderX and Series/KamenRiderSkyrider having been originally converted to cyborgs after suffering serious injuries.
* ''Series/TheOuterLimits1995'' episode "Music of the Spheres" has aliens subjecting the whole of humanity to signals that people think are music, but causes mysterious changes. Instead of the CruelTwistEnding the series is known for, it turns out it's an Emergency Transformation into bald, large-headed, golden-skinned creatures, so that they can survive an impending shift in the sun's radiation. The aliens' process initially only works on people close to puberty, but once the humans figure out exactly what the hell is going on and why, they manage to enhance the process so that it can be applied to anyone. Some of the characters refuse to go along with the transformation; as one of the main characters puts it, he wants his wife to be able to recognize him in Heaven.
* ''Series/{{Now and Again}}'': [[spoiler: Michael Wiseman is killed in a subway accident but secretly given the chance to have his brain placed inside a genetically bio-engineered body with superhero like abilities]].
* ''Series/{{Supernatural}}''
** This trope is played with this when, in the first episode of season 9, [[spoiler:Sam is dying and Dean makes the decision to let an angel use his body as a vessel in order to save his life from the inside]].
** Also in season nine, [[spoiler:a currently human]] Castiel is captured by a faction of angels who torture him for information he doesn't have and refuse to believe/don't care that he doesn't have it. When his torturer's boss leaves them alone, however, the torturer offers to help him if Castiel will [[spoiler:contact Metatron and convince him to let the torturer join ''his'' faction.]] This is one of the things Castiel already told them he can't do, since [[spoiler:Metatron simply used him and they are not even remotely friends at this point]], but since the torturer won't believe that, Castiel pretends to agree and is temporarily released to do it. He quickly grabs the nearest angel blade and [[spoiler:steals his torturer's Grace before killing him, transforming back into an angel]] to heal his injuries and have the power to fight his way out of the compound. In a variation of the trope, [[spoiler:he was originally an angel to begin with,]] but he's not particularly happy about the brutality of what he had to do to survive, and the [[spoiler:stolen Grace]] in fact becomes an issue later, as it's not fully compatible with him and he suffers physically from the fall out.
** In another episode, a werewolf's sister is dying from a car accident, so the werewolf bites her, assuming (correctly) that becoming a werewolf would heal the injuries and save her sister's life. The werewolf in question is also a good person who subsists on animal hearts, so she teaches her sister to do the same. [[spoiler:This does not end well.]]
* ''Series/LukeCage2016'': The experiment that gave Luke his super-durable skin was the result of an attempt to save his life after Shades and Comanche beat him into the prison infirmary for planning to snitch on Rackham.

* The eponymous character in The Doctor's Wife by Music/ClockworkQuartet has parts of her body being shut down by some unnamed malady while the Doctor has to keep replacing them with mechanical bits.
* In ''[[Music/SoundHorizon Seisen no Iberia]]'', Layla (dying from an arrow through the chest) is given the choice by a sealed demon to either die as a human or live on forever as a demon - [[DealWithTheDevil provided she frees him, of course]]. She chooses the latter. [[spoiler:Strangely enough, freeing a murderous demon turns out to be a phenomenally good plan.]]

[[folder:Tabletop Games]]
* The ''TabletopGame/{{Shadowrun}}'' second edition {{sourcebook}} ''Cybertechnology'' has a framing story that involves a badly injured runner being transformed into a "cyberzombie" (i.e. being loaded up with enough cybernetics to kill him, with only incredibly powerful magics actually keeping his soul bound to his body). Game stats for the transformation, and for a ton of cybernetic gear, are given between paragraphs of his descriptions of the horrors of the transformation.
* Generally averted in the TabletopGame/{{Ravenloft}} setting, where becoming a vampire or lycanthrope is typically regarded as a fate worse than death. An ailing Anna refused Jander's attempt to transform her in the novel ''Vampire of the Mists''.
* In ''TabletopGame/{{Warhammer 40000}}'', in the rare event a [[SuperSoldier Space]] [[SpaceMarine Marine]] sustains injuries too grievous for his robust physiology to recover from but which aren't enough to kill him, he may be interred with an armored life-support sarcophagus, allowing him to pilot a walking tomb/tank called a [[MiniMecha Dreadnought]]. Such warriors are venerated as their chapter's greatest heroes and wisest leaders, allowed to slumber away the centuries when their skills aren't needed. Bjorn the Fell-Handed is the most famous example, a Space Wolf who fought alongside the Emperor during the Great Crusade ten thousand years ago.
** [[EvilCounterpart Chaos Space Marines]] also have Dreadnoughts, but consider confinement within one to be [[AndIMustScream the ultimate in torture]], an eternal punishment for their failure in battle. [[ForTheEvulz This is not to say that Chaos Marines don't end up in Dreadnoughts anyway]], but such unfortunates go quite mad, even by Chaos' standards. In combat they have a tendency to [[CriticalFailure fire upon their own side]] or go into [[TheBerserker berserker killing sprees]], while outside of battle their sarcophagus is removed from the Dreadnought, which is then chained to a separate wall, just to be safe.
** The [[SpaceElves Eldar]] have adopted this on a racial scale - every one of them wears a [[SoulJar Waystone]] at all times, which will capture their soul upon death and allow it to be placed within their Craftworld's Infinity Circuit for all eternity. It's not a true afterlife, much less a paradise, but the alternative is having their soul [[FateWorseThanDeath consumed by the Chaos God Slaanesh]]. In dire emergencies an Eldar's soul may be recovered from the Infinity Circuit and used to pilot a Wraithguard or Wraithlord construct in battle, but the Eldar view this practice as akin to necromancy, since it's irreversible and means that the pilot's soul is lost if its Wraith-construct is destroyed.
*** There's a variant for Phoenix Lords. They can be killed, but resurrect by subsuming the soul of an Exarch into themselves. The Exarch becomes the new incarnation of the Phoenix Lord, but their original personality is completely buried.
** Ork Painboyz are happy to perform emergency transformations. With or without consent. Or an emergency.
** While Angron's transformation into a Daemon Prince had plenty of other benefits, the main reason Lorgar helped him ascend was to save him from dying due to the Butcher's Nails slowly degrading his brain. However, the transformation also caused the Nails to be bonded even deeper into his body with flesh growing over them. While the Nails won't kill Angron anymore, they are now even more a part of him.
* ''TabletopGame/DungeonsAndDragons'':
** The {{Reincarnat|ion}}e spell is often the poor man's [[DeathIsCheap Raise Dead]]: cheaper, but the character comes back as a random humanoid species, or in older editions, any species at all. Whether it's a step down or CursedWithAwesome depends on the luck of the draw and the player's tastes.
** Besides the standard vampire transformation, there are many ways to become undead. For example, wizards can become liches well before getting their own healing magic, though the availability of {{healing|Hands}} and resurrection magic in most settings makes it a poor choice for most characters. For a wizard who [[ImmortalitySeeker doesn't want to die of old age]], however...
*** One spell automatically animates the target as an undead being when they die, at the cost of [[CastFromHitPoints weakening them in life]].
* In ''TabletopGame/{{Aberrant}}'', it's a well-established fact that an Eruption can be triggered by placing yourself in a deadly situation, and hopeful Nova-wannabes try to orchestrate specific situations to get just the right powers (jumping off a plane is popular because flying is awesome). The most commonly-mentioned downside is that you might get lame and/or stupid-looking powers instead. Strangely they don't much mention the fact that potential for Novahood is rare, and most people who try this tactic end up dead instead.
** The Paragons setting for ''TabletopGame/MutantsAndMasterminds'' has a situation similar to TabletopGame/{{Aberrant}}, though the "spark parties" and "origin chasers" tend to have [[ATragedyOfImpulsiveness unfortunate results]]. The page illustration is a girl looking at a newspaper article about the hero Blaze whilst soaked in petrol and what looks from the empty bottle nearby to be drain cleaner and holding a lit match.

* In the musical ''Theatre/{{Wicked}}'' Elphaba turns [[spoiler: Boq into a Tin Man after Nessa literally destroys his heart and Fiyero into a Scarecrow while the soldiers are torturing him]], saving their lives.

[[folder:Video Games]]
* Fatima, the VoiceWithAnInternetConnection in the PC game ''VideoGame/{{Anachronox}}'' was originally the main character's secretary until she died in a car wreck. The protagonist couldn't live without her, so he had her digitized. [[spoiler: It's later revealed that he felt he was to blame for the reckless actions that resulted in her death (and he kind of was), so he digitized her to save her life as best he could. It's implied that he feels terribly guilty about it, as she's essentially trapped in the [=LifeCursor=].]]
* Asellus, of ''VideoGame/SagaFrontier'' is run over by a carriage before the game starts and given a [[strike: Vampiric Blood Transfusion]] Mystical Blood Transfusion by Charm Lord, turning her into a half-mystic.
** In addition, Red is turned into a SuperHero after the first battle with Shuzer, as he would have died otherwise.
* In the [[MultipleEndings Bad Ending]] of ''VideoGame/{{Pikmin}}'', [[spoiler:Olimar does not repair his rocketship in time and his supply of whatever it is he breathes instead of oxygen runs out, so the Pikmin save him by transforming him into one of them.]]
** Especially interesting, since it is actually foreshadowed in the game!: [[spoiler: One of Olimar's journal entries states that he would actually ''want'' to become a Pikmin, since his boss is not exactly a nice guy. He however suddenly changes his mind, when he remembers having a family waiting for him.]]
* This might be the case for Yoshimitsu from ''[[VideoGame/SoulSeries Soul Calibur]]''.
* In ''VideoGame/StarCraft'', Protoss warriors who are mortally injured are transplanted into Dragoon exoskeletons, where they can continue to fight. However, they volunteer for this, and so tend to be pretty stoic about it. Their people praise them for their devotion.
** In the sequel game, dragoons are no longer used and protoss warriors are rebuilt as {{Cyborg}}/PoweredArmor warriors called [[NamesToRunAwayFromReallyFast immortals]]. [[http://bestgamewallpapers.com/files/starcraft-2/protoss-immortal.jpg And they look fucking badass.]]
* Happens to Samus in the intro of ''[[Franchise/{{Metroid}} Metroid Fusion]]''. After being attacked by an X-parasite, she's [[LegoGenetics transfused with Metroid DNA]] to stop the infection. [[TheyWastedAPerfectlyGoodPlot Unfortunately]], since ''Fusion'' is chronologically the last game in the franchise, the long-term effects of such an operation (both physically and mentally) have yet to be shown.
* {{Subverted|Trope}} in ''Videogame/ShinMegamiTenseiIIINocturne'': The blond child gives the Protagonist a Magatama that turns him into the Demi-Fiend during TheEndOfTheWorldAsWeKnowIt. It's a subversion because it was previously stated that the Protagonist would have survived with or without becoming a demon.
* A variant on this trope is a recurring theme in the ''VideoGame/{{Suikoden}}'' series: True Runes are almost always acquired by someone who needs to use its power to escape from a deadly situation, put up a decent fight against an overwhelming foe, or keep the Rune itself out of the hands of those who would misuse it. [[BlessedWithSuck They often learn to regret this decision]].
* Bonding with a dying human host by a usually injured [[EnergyBeings Kheldian]] is the canonical usual origin of the Peacebringers and Warshades in ''VideoGame/CityOfHeroes''.
* In ''VideoGame/BreathOfFireII'', the party needs to fly to a particular location, but the only way any of them know to do this is by having Nina permanently transform into a [[GlobalAirship giant, non-sentient bird]]. Just before she's about to do this, [[spoiler:[[HeroicSacrifice her little sister sacrifices herself by undergoing the transformation herself]]]]. Of course, this whole situation invokes a certain amount of {{Narm}} since what they're trying to fly to is merely an island whose cliffs [[InsurmountableWaistHeightFence lack a path the game will allow you to climb up]].
* In the Creator/LucasArts AdventureGame ''VideoGame/TheDig'', the team discover "life crystals," which have the ability to heal wounds and resurrect the dead at the cost of being literally maddeningly addictive, as evidenced by Brink's slow decent into insanity. Robbins makes Low promise that if anything should happen to her, he won't use the crystals to revive her.
** Unsurprisingly [[spoiler:she ends up dying in the process of saving the day. If you finish the game without her, she thanks you for keeping your promise when the aliens resurrect everyone (madness free). However, if you ignore her wishes and bring her back yourself, she's horrified and immediately throws herself off a cliff. When she's brought back to life at the end of the game, she's still pissed at you for that]].
* This is part of the plot for ''{{VideoGame/Bulletstorm}}''. Grayson saves Ishi using mechanical parts of questionable efficacy. While Ishi functions pretty well physically after his transformation, he runs into [[CyberneticsEatYourSoul some other]] new [[AIIsACrapshoot problems instead]].
* The titular character of the ''VideoGame/MegaManBattleNetwork'' series was born with a fatal heart defect and used as the guinea pig for his father's and grandfather's experiments in BrainUploading. Ten years later, he was given as an "AI" partner to his own twin brother. This plot point was [[strike:never brought up]] taken out completely in the anime.
* ''VideoGame/ResidentEvil2'': BigBad Dr. Birkin, after being fatally shot by Umbrella agents, injects himself with the [[PsychoSerum G-virus]], transforming him into his monstrous OneWingedAngel form.
* In ''VisualNovel/{{Ever17}}'' at the end of two/three routes [[spoiler:Tsugumi shares her blood with Takeshi, You, the Kid and eventually Coco. She's the hesitant one as while it's supposed to only be so they get her antibodies, it could give them the Cure Virus and make them [[CursedWithAwesome immortal, unaging, have a]] HealingFactor [[CursedWithAwesome and see in the dark]]. And also potentially have a bunch of people try to capture them for research... So at the end of the story about three fourths+ of the cast is immortal]].
* In ''VideoGame/SuperPaperMario'', [[spoiler:Tippi was originally a human, and was turned into a Pixl by Merlon in a desperate attempt to save her life]].
* ''VideoGame/{{Iji}}'' starts with this.
* Rachel has done this, possibly twice in ''VideoGame/BlazBlue''. [[spoiler:First to save a mortally wounded and time-displaced Jin by [[WeCanRebuildHim installing him in the Susanooh Unit]] to become Hakumen.]] It's also possible [[spoiler:that Ragna would have bled to death after losing his arm in the orphanage attack without Rachel biting him to transform him into a half-vampire.]]
* In ''VideoGame/QuestForGloryII'', Julanar is a woman who, while fleeing from brigands, is discovered by a djinn who [[{{Transflormation}} transforms her into a tree]] in order to save her from her pursuers.
* Given the themes of the series, this crops up in the histories for a number of characters in the ''Deus Ex'' franchise.
** In [[VideoGame/DeusEx the original game]], this trope was part of the back-story for how Agents Hermann and Navarre became mech-augs.
** At the end of the tutorial mission in ''VideoGame/DeusExHumanRevolution'', Adam gets the ''shit'' kicked out of him and then shot, brought to the very brink of death. To keep him alive, he's augmented - turned into a cyborg - by his boss and the company he works for. They replace his arms, legs and heart and stick machines into just about anything you can stick a machine in. When the gameplay kicks in again, he's very different.
*** Notably, only the arm and chest replacements were necessary for him to survive. The rest was his employer using his contract to gain power of attorney (darkly alluded to in the intro sequence when David Sarif is heard saying "He doesn't need that"). [[spoiler: Later in the game you find out that Jensen is the only individual whose body accepts augmentations without the need of drugs to stave off rejection, due to extensive genetic manipulation, so his employer (who was aware of this fact) was also having an experimental field day with Jensen as well.]]
* In ''VideoGame/WorldOfWarcraft: Cataclysm'', many of the [[spoiler:surviving humans in Lordaeron who remain loyal to the Alliance [[VoluntaryShapeshifting voluntarily]] take up the [[OurWerewolvesAreDifferent worgen curse]] to immunise themselves from being [[TheAssimilator raised into undeath]] by their arch-enemies, the Forsaken]].
** The whole naga race is the result of an Emergency Transformation .
* At the end of ''VideoGame/HalfLife2'', [[TheQuisling Doctor Breen]] is protesting being put into a "host body" as the only way to survive teleportation. Speculation is that he is one of the slug-like Advisors that attacks Gordon and Alyx throughout the Episode sequels.
** Although he probably dies when Gordon damages the teleporter.
* ''VideoGame/HeroesOfMightAndMagic'':
** Gauldoth Half-dead from the fourth game. During the Armageddon which destroyed the old world he attempted to save himself by undergoing a ritual of lichdom. Because he was only an apprentice necromancer, he emerged from the ritual with one half of his body as that of a living human, and the other half zombified.
** In the sixth game, Moander's backstory states that he was poisoned with manticore venom, but managed to acquire a vial of namtaru spider venom [[note]]Namtaru spiders are worshipped by necromancers, and their venom is used in the rituals to create liches and vampires[[/note]], and drank it thinking it would give him eternal life. It did... but the combination of the two venoms ravaged his body and seared most of his flesh, giving him the appearance of a living skeleton.
* In ''VideoGame/FrontMission'', [[spoiler:Driscoll is part of an experiment into using the brains of human soldiers to create advanced computers. After his death, he is resurrected and serves as a component in the HumongousMecha FinalBoss]].
* In one ending in YuriGenre VisualNovel ''VisualNovel/AkaiIto'', [[spoiler:Kei is turned into the "something not human" by Sakuya to save her life after she was [[ImpaledWithExtremePrejudice fatally wounded]] by Nushi. [[CursedWithAwesome It's better than it sounds]], because she now kick asses for eternity alongside Sakuya]]. The outcome of said ending was made into a mini-game in the sort-of sequel ''VisualNovel/AoiShiro''.
** On the same character route is [[spoiler:when Sakuya's power is not enough to transform Kei, so both of them become Ohashira, replacing Yumei. Quite close to being TogetherInDeath]]. Yumei does feel sorry for them.
* In ''VisualNovel/ElevenEyes -Resona Forma-'', we see that this is how the Black Knights were created. Liselotte thoroughly beat all of them except for George, who finished [[SealedEvilInACan sealing her before he died]], and Misao, who clothed her partners in armor made out of dark spirits, turning them and herself into Liselotte's guardians.
* ''Franchise/DragonAge'':
** ''VideoGame/DragonAgeOrigins'' has the Dalish Elf Origin. Basically, your character becomes tainted and has to undergo the Grey Warden Joining in order to have a chance of survival.
** In ''VideoGame/DragonAgeII'', if you take your sibling with you for the Deep Roads Expedition, [[spoiler: they will contract the Taint, and the only way to save their life is to have them undergo the Grey Warden Joining. Hope you brought Anders with you as well, as he's the only guy who can lead you to the Wardens.]]
* ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R. 2: Project Origin]]'' has a variant of this when [[spoiler: Beckett is surgically implanted to boost his psychic abilities and link him to Alma]]. However, while the transformation is an emergency, it is ''not'' intended to save the patient's life, but rather to [[spoiler: draw Alma's attention toward Beckett after she has escaped containment, in order to keep her distracted and ultimately lure her into another containment device to seal her away]].
* In one ending of ''VideoGame/DuelSaviorDestiny'' Taiga [[spoiler:becomes the Messiah]] and to avoid the terrible consequences this would cause [[spoiler:Rubinas]] stabs him in the heart and [[spoiler:turns him into a homunculus like herself]]. He seems okay with it, though it took him rather by surprise.
* ''VideoGame/DarkSouls'': The game implies that the Daughter of Chaos was made a Fire Keeper as a means of magical life-support. [[HeroicSacrifice Sucking the blight pus from her servants]] nearly killed her, and even in her current condition [[TheWoobie she's blind, immobile, in constant pain]] and [[BodyHorror endlessly giving birth to bloody, stillborn eggs]].
* In the Good Ending of ''VisualNovel/FateStayNight'''s ''Heaven's Feel'' route, this happens to Shirou in order to save his life. [[spoiler:Shirou is pretty much dead on his feet, with his entire body having been turned into swords from the inside out, so Ilya uses the Third Magic to transplant his soul into... something else (it's never really said what). In the epilogue, he's been put into a magically-created artificial human body, but it still needs further refinement, and Rin is seeking out [[LightNovel/KaraNoKyoukai Touko Aozaki]] for that purpose.]]
* In ''VideoGame/TheWorldEndsWithYou'', after [[spoiler:Rhyme is erased by a noise, Mr. H Quickly puts her soul in a pin, turning her into an adorable little squirrel noise thing. She gets back to normal eventually]].
* The Lords of Amber Plains of ''Videogame/EndlessLegend'' faced a stark choice when [[JustBeforeTheEnd Auriga's climate began to collapse]], freezing their crops; death by starvation, or survival by binding their [[AnimatedArmor souls to suits of armor]]. Now transformed into the Broken Lords, they have a significant amount of angst over the fact that they must [[LifeDrinker drain energy from living beings to sustain their bodies]], betraying their vows as [[KnightInShiningArmor honorable knights and builders]].
* Characters with the "Bionic Patient" profession in ''VideoGame/{{Cataclysm}}'' have this as their backstory, where they underwent Bionic augmentation in order to survive an otherwise terminal illness.
--> "When the diagnosis came back positive you signed up for a series of experimental bionic surgeries that saved your life. Now you're healthier than you ever were before, thanks to a suite of bionic systems powered by standard batteries. Make the most of your second chance at life."
* In ''Videogame/VampireTheMasqueradeBloodlines'', you can give some of your blood to Heather, a young girl dying from a traffic accident, in order to save her life. While this is physically beneficial (she survives and recovers quickly, as well as becomes stronger and healthier), it also makes her develop a psychological bond with you, essentially acting like she's drugged / in love with you and can't be without you (and your blood). She also does a few questionable things to appease you, ranging from giving you her money to luring home a guy and locking him up in the bathroom as a "meal" for you. [[spoiler:If she stays with you past a certain plot point, she'll get murdered by the Sabbat for the explicit purpose of punishing you. It can be avoided by ordering her to leave you, never come back, and try to forget everything. Either option is, according to many players, completely heartrending.]]
* Graham escapes from [[OurVampiresAreDifferent Caldaur]] in the FanRemake of ''VideoGame/KingsQuestII'', by warning him that his still-human wife is on the verge of death. Upon hearing this, Caldaur immediately leaves so he can turn her into a vampire and stop her from dying.
* Part of Torvald's backstory in ''VideoGame/{{Evolve}}''. Left torn basically into pieces in a wrecked spaceship floating through space with all other crew dead, he gave the ship's robots one final command: "Repair me." Now he's a head, one arm, and a chunk of a torso grafted onto a robotic body that includes features like a jetpack, mortar cannons, a target designation laser, and a personal forcefield, all powered by a fusion core that burns what he eats as fuel to keep him alive.
* In ''Videogame/{{Gungrave}}'', Bob Poundmax's BigEater habits eventually caught up with him. He would have died of a blood clot in his brain if he hadn't been transformed into a Superior(an Orgman capable of free will/sentient thought). Not only did this save his life, it granted him superhuman abilities and even allowed him to keep enjoying chicken drumsticks.

[[folder:Web Comics]]
* Both werewolves and vampires in ''Webcomic/{{Sorcery 101}}'' have extraordinary resilience compared to humans, making them candidates for this trope. So do humans magically linked to vampires, called "blood bonds". In the main protagonist's backstory, he was seriously injured fighting demons. His [[HeterosexualLifePartners best friend]] Brad knew a vampire named [[MagnificentBastard Seth]], and asked him to help, so Seth made Danny a blood bond. Danny seems to be OK with this in general (immortal, can't get sick or gain weight, can't bleed to death, stuff like that), but isn't happy about having to deal with Seth.
** A more recent example is that of [[OurWereWolvesAreDifferent Brad]] turning his new boss's daughter into a werewolf upon request, as she was bedridden and dying of some illness.
* One of the older patients of ''Webcomic/TheDragonDoctors'' from the webcomic of the same name turned herself to stone to avoid dying of thirst. Thing is, she couldn't willingly revert on her own. She had to wait for someone to find her to undo the transformation--locked away in an abandoned mine, behind a magical forcefield, in the middle of nowhere. Sanity was... something of a concern.
** In the same arc, when a crystalline girl is injured, Sarin changes her into a human because it's easier to heal; it's reversible, though.
** And still more recently, we discover that the person who bankrolls our heroes ended up with a condition that caused her to age quickly enough that even the easily available youthening magic of the setting couldn't keep up... so they turned her to stone (as per the above example) except that she had a psychic communicating with her whenever she needed it which not only kept her sane, but allowed her to run her parents' business. After the discovery of a sapient crystalline species, Sarin was able to turn her into such as a vastly superior alternative (since that species has no aging).
* In ''Webcomic/HannaIsNotABoysName'', Hanna saves Conrad this way by [[http://web.archive.org/web/20100315202321/http://hanna.aftertorque.com/?p=89 turning him into a vampire]]. (No one was really surprised by this but Conrad).
* One of these occurs in the first chapter of ''[[Webcomic/CogaSuro Coga Suro 2]]'', but a slight variation in that John is transformed into... whatever that is in order to save himself and a girl after they're both swallowed by a giant maw.
* Done to the character Dark Eyes to save her life in ''Webcomic/MagicalMisfits'', magically mixing in genes from many different other species in the process that rendered her sterile. [[spoiler:Temporarily]].
* In ''Webcomic/{{Drowtales}}'', [[spoiler:Kiel'ndia]] is fatally poisoned and would have died if Kharla'ggen hadn't ''insisted'' that Larvova heal her. Since it's a bad idea to tell Kharla'ggen that she can't have what she wants, Larvova is forced to take drastic measures. [[http://www.drowtales.com/mainarchive.php?sid=7375 This is the result.]] Kharla'ggen, being a somewhat odd individual, thinks that [[spoiler:Kiel'ndia]] is lucky [[spoiler:since she still has one of her original eyes. That's ''all'' she has left of her original body. Or not, since it was AllJustADream.]]
* In ''Webcomic/DeathAndTheMaiden'', [[spoiler:Death tries to heal Mercedes's tuberculosis (caused by a run-in with Pestilence) and in doing so, accidentally turns her immortal. Then he later realizes he didn't just make her immortal, he turned her into ''Death'']].
* In ''Webcomic/TheOrderOfTheStick'' prequel ''Start of Darkness'', [[spoiler:Xykon willingly undergoes the transformation into a lich after contact with a magical disease robs him of his magical abilities]].
* In ''Webcomic/CollegeRoomiesFromHell'', when Marsha is pushed off the roof by Chester, she escapes by... spontaneously growing bat wings, suggested to be a latent effect of a [[ILoveNuclearPower radioactive]] "batato" that had earlier bitten her. Since half the cast had long since undergone similar transformations (without the emergencies), she adapts fairly quickly.
* In ''Webcomic/CityOfReality'', Danny turns a fatally-wounded AV into an Atari-like device; they eventually turn her back, but not before his WellIntentionedExtremist mentor tries to destroy her.
* In ''Webcomic/MSFHigh'', it's generally understood that anyone who goes to Nurse Keiri's office will be leaving as a female of the species easiest to treat, and she'll be doing everything in her power to keep them that way. The backstories of many [[TheVirus Legion]] end similarly.
* This happens in ''Webcomic/ModestMedusa''. [[spoiler: The boy who lives with Gorgon starts turning into a monster, so she saves him by [[http://www.modestmedusa.com/?p=768 turning him into a horse.]]]]

[[folder: Web Original]]
* The origin story of Hive in the Literature/WhateleyUniverse. Sam Everheart is dying from injuries, and the nanotechnology he's been exposed to rebuilds him using the only untainted [=DNA=] nearby, from a lock of hair belonging to his deceased daughter.
* Roleplay/MSFHighForum: Too many examples to list. The Nurse's Office is the main cause of this. Often subverted, as the office has used it for non-dangerous transformations.
* At the end of ''WebVideo/TheCartoonMan'', [[spoiler:Karen is mortally wounded, and Roy saves her life by using black ink to transform her into a human cartoon]].
* In [[http://parahumans.wordpress.com/2013/08/24/extinction-27-5/ Chapter 27.5]] of ''Literature/{{Worm}}'', [[spoiler:Taylor]] uses [[spoiler:Lab Rat's device]] to undergo a temporary transformation into [[spoiler:a monstrous, insectoid form]] after suffering lethal injuries at [[spoiler:Scion]]'s hands.
* In an early WebOriginal/ShadowrunStorytime session, Geppetto gets a chestful of automatic gunfire. The closest the team has to an emergency trauma surgeon contact is a ghoul organlegger named John. If he does the work, Geppetto ''will'' contract HMHVV. Geppetto acknowledges the risk and accepts it. Dr. John has him infected with a different strain first so he turns into a banshee instead of a ghoul, something that can still pass for metahuman.

[[folder:Western Animation]]
* Insofar as a steam engine can actually ''need'' one of these, Henry gets one in season 1 of ''WesternAnimation/ThomasTheTankEngine'' after his crash with The Flying Kipper. Turned out for the best, since the locomotive works took the opportunity to perform some upgrades; he didn't need Welsh Coal anymore afterwards and was strong enough to pull express trains single-handed.
* Keldor from ''WesternAnimation/HeManAndTheMastersOfTheUniverse2002'' went through one soon after he was HoistByHisOwnPetard in the pilot. It turns out that the acid that hit his face was actually killing him; he pleaded with [[SealedEvilInACan Hordak]] to save him. [[DealWithTheDevil Hordak agreed, warning Keldor that there would be a price for this favor]], and transformed him into a lich-like abomination. Hordak then bestowed upon Keldor the name Skeletor. Upon seeing his hideous new appearance, Skeletor promptly burst into [[LaughingMad a fit of maniacal laughter]] (the first of many), signifying his transition from a smooth talking and charming EvilOverlord to an insane and superpowered monster.
* ''WesternAnimation/ExoSquad'' used this for the ''ultimate'' emergency, death. The brain-scans of deceased troopers were downloaded into customized human-looking but internally Neo Sapien bodies. Started as a Trojan Horse plot by Phaeton, but it worked so well that the humans soon saw the obvious benefits. The only downside is that there have to be recorded memories from an Exoframe [[UnusualUserInterface brain jack]] to transfer.
* ''WesternAnimation/SWATKats'': [[OutlawCouple Gangster couple]] Mac and Molly Mange drown while escaping from prison; their bodies are found by kindly scientist Professor Hackle, who [[BrainUploading uploads their minds]] into robotic bodies. They promptly steal Hackle's [[CoolCar armored hovercar]] and [[ForScience weapons stash]] and go back in business as the invulnerable Metallikats.
** And despite their clear, obvious, and constant treachery, Hackle keeps collecting their battered remains and rebuilding them.
* This is the backstory of ''WesternAnimation/EvilConCarne''. After his body was destroyed in an explosion, Major Dr. Ghastly attached his {{brain|InAJar}} and stomach to a bear.
* In the final season of ''WesternAnimation/DarkwingDuck'', Taurus Bulba is revived as a cyborg by FOWL. He's... not exactly happy about it. Of course, fitting the big guy, rather than angsting about it at all, he just gets [[UnstoppableRage pissed]].
-->'''Taurus Bulba''': So, you ''[[SarcasmMode allow]]'' [[SarcasmMode me to be part of your]] ''[[SarcasmMode great]]'' [[SarcasmMode experiment]], without bothering me with petty nuisances such as... ''getting '''my permission'''''.
-->''Collective OhCrap from every member of FOWL present, including '''Steelbeak'''''.
* This is heavily implied to be behind Zachary Foxx's bionics in ''WesternAnimation/AdventuresOfTheGalaxyRangers''; in the {{Pilot}}, "Phoenix," he was shot several times on his left side. CyberneticsEatYourSoul is ''completely'' averted in this case, as Zach's been SupernaturallyDeliciousAndNutritious for more than one magic-slinging foe.
* ''WesternAnimation/BionicSix'' starts off with the titular family being exposed to radiation, with only TheProfessor's conversion machine available to save them.
* Prior to God Ginrai's Emergency Transformation in ''Anime/TransformersVictory'', Spike Witwicky is a temporary example in the aptly titled "Autobot Spike" of the [[WesternAnimation/TheTransformers original cartoon]]. Sent into a coma after a Decepticon attack, Spike's mind is [[BrainUploading transferred]] to a robot frame his father was working on earlier, in order to let the human doctors operate on his body safely. Toss in references to the original Frankenstein, the fact that the body is a mishmash of parts, and a little bit of [[CyberneticsEatYourSoul Con trickery]]... He eventually recovered, though.
** However, Daniel underwent the Headmaster process and became Arcee's partner after being ''half-eaten'' by a beast Decepticon (You'd think nearly doing in TheScrappy would have [[CrowningMomentOfAwesome made him a household name]], but no.) and will presumably be stuck in that exosuit ''forever.'' [[AlasPoorScrappy Poor guy]].
** The MidSeasonUpgrade of Hot Shot, Red Alert, and Scattorshot from ''Anime/TransformersCybertron'' also counts. They were dying, grievously injured by Megatron's newly-unlocked Death Machine Gun. The source of this transformation? Divine intervention by a semi-conscious Primus.
** And while we're at it, technically this one covers [[DealWithTheDevil Megatron becoming Galvatron]] in ''WesternAnimation/TransformersTheMovie''.
** The MECH organization in ''WesternAnimation/TransformersPrime'' performs a rather ghoulish example of this, using a Decepticon corpse as life support for their critically-wounded leader.
* Tom from Creator/{{Toonami}} underwent a change when the Absolution was overrun with an alien blob and Tom 1.0 was swallowed up by it.
* This was Sir Charles Hedgehog's motivation for inventing the Roboticizer in ''WesternAnimation/SonicSatAM''. He abandoned the project when it turned out it would rob the subject of their free will. Unfortunately, the FallenHero war minister with plans for world domination stole the plans.
* In ''{{WesternAnimation/Robotix}},'' the Protectons and Terrakors intend to survive a solar flare's devastation by going into [[HumanPopsicle suspended animation]] deep underground. Afterward though, their central computer decides there is no way for them to survive on the devastated world after all, and transfers the minds of a few of them into [[HumongousMecha giant construction robots]] called [[TitleDrop "robotix."]] Upon awakening, [[BodyHorror they don't take it well]].
--> '''Argus''': What has happened? I have ''become'' a Robotix! ''[[BigNo NOOOOOOOOO!!!]]''
* In ''WesternAnimation/{{Centurions}}'', MadScientist Doc Terror transforms street thug Hacker into a {{cyborg}}, then tells him that there's no way to change him back. Hacker's reaction is a temper tantrum that leaves Terror with life-threatening injuries, so Terror has to become a cyborg himself to survive. It would be a case of HoistByHisOwnPetard, except that Terror ''likes'' his new form.
* The ''WesternAnimation/AdventureTime'' episode [[WhamEpisode "Betty"]] ends with [[spoiler: Betty defeating Bellanoche and restoring the Crown's magic, keeping Simon alive but turning him back into Ice King]].
