* In ''VideoGame/HollowKnight'', the "Embrace The Void" ending reached by defeating the Pantheon of Hallownest in Godhome [[FromNobodyToNightmare sees the humble Knight metamorphose into a]] [[AttackOfTheFiftyFootWhatever towering]], [[CombatTentacles tentacled]], [[HornsOfVillainy horned]], [[ExtraEyes multiple-eyed]] [[EldritchAbomination Void demon]] that [[CurbstompBattle crushes the Radiance like a bug]](no pun intended), then completely takes over Godhome and begins to reach into Hallownest itself via the Godseeker.

* The final cutscene of ''VideoGame/ChaosHeat'', after you destroy the last mutated monster, have you boarding an evac chopper and having a conversation with a {{redshirt}}. Cue a ReactionShot of the redshirt seeing something horrifying, before cutting back to your character - now a mutant monster yourself, having been infected during your escape. You could unlock an ending that averts this trope, by destroying 90% or more Chaos Cores spawned by slain enemies, but getting this result is HarderThanHard.

* ''Film/TheSearchers'': The final escene of the movie suggest, and WordOfGod confirms that the ultimate fate of [[TragicBigot Ethan Edwards]] is to [[BarredFromTheAfterlife wander "between the winds"]], like the Indians believe will happen to anybody whose corpse has no eyes, [[LaserGuidedKarma and the destiny Ethan has invoked over]] [[DesecratingTheDead a dead Comanche in the middle of the movie by shooting his eyes from his corpse]]

* In ''Film/TerminatorGenisys'' John Connor, leader of the human resistance against the Terminators, is turned into one himself as a last ditch effort by Skynet.

* Near the end of ''Film/UndeadOrAlive'', Elmer makes the mistake of punching an infectious zombie in the mouth, and almost immediately realizes that he is beginning to turn. While he uses the last few moments before the hunger overwhelms him to attempt to make a Heroic Sacrifice, he succumbs in the end, infecting one companion and convincing him to help devour another.

* ''Literature/AbrahamLincolnVampireHunter'' has the twist ending of... well, guess.

* Whenever a person dies beyond the Wall in ''Literature/ASongOfIceAndFire'' their body becomes a reanimated [[OurWightsAreDifferent wight]] which is forced to kill all living people at the behest of their masters, the [[CreepyBlueEyes Others]]. Up until the Winds of Winter, this has happened to several characters:

** At the end of ''VideoGame/{{Diablo}}'', the hero defeats the titular boss and jams its [[SealedEvilInACan soulstone]] in his/her own forehead to contain it. This results in the hero becoming the new BigBad in ''VideoGame/DiabloII''. This was later [[RetCon Ret-Conned]] in ''VideoGame/DiabloII'' by saying that said hero was more or less [[MindRape Mind-Raped]] into doing so.

* If you choose the "Survive!" or "Fight Back!" ending in Story Mode in ''Videogame/SurvivalistInvisibleStrain'', it's revealed that nearly everyone in Moose Valley has been infected by the [[AntagonistTitle titular Invisible Strain]] from eating the [[TheSecretOfLongPorkPies fake vension]], turning them against you. You then have to fight your way through your turned former friends and allies and escape.

** In ''VideoGame/StarCraft'', Kerrigan fights the Zerg during the Terran campaign but becomes one during the Zerg campaign. She gets better... and then she ''re-infests'' herself for the second time.

* In ''VideoGame/{{Castlevania 64}}'s'' DownerEnding, you get this on two levels; a side character, Vincent the vampire killer, becomes a vampire. Also, Carrie agrees to marry Malus (Dracula), to which he ominously notes that they have "a binding contract".

* Many of the characters in the live action adaption of ''Series/{{Goosebumps}}''. Most episodes follow the books to the letter. But a noticeable deviation is ''Vampire's Breath'': in the book, the whole adventure was played straight in which the protagonists spend the whole episode trying to avoid getting bitten and eventually succeed (though one of them takes a substance meant for werewolves). In the TV version, however, the two find out that their whole family are vampires (the one chasing them was actually a relative) and that the siblings have now come of age where their fangs have grown in.

* ''Film/ZombielandDoubleTap'' has Madison supposedly becoming zombified after fighting a bunch of zombies at an RV site and Columbus had no choice but to [[MercyKill put her down]]. Subverted when it turns out Madison's "zombification" was just an allergic reaction to almonds in her trail mix, plus Columbus never shot ''at'' her, just besides a tree in order to scare her away.
** Played straight with both Albuquerque and Flagstaff, Tallahassee and Columbus' counterparts who get turned into [[Film/Terminator2JudgmentDay T-800]] zombies while fighting an army of them. They are both defeated by Tallahassee [[OtherMeAnnoysMe (who hates Albuquerque)]] and Nevada.

* In the end of ''VideoGame/AloneInTheDark2008'', [[MortonsFork either Carnby or Sarah]] becomes a demon of Lucifer.

* ''VideoGame/ArteryGearFusion'': This happened in the past to Cream. She was attacked by a puppet and had nearly permanently transformed into a puppet herself. Only a last-minute transformation into an Artery Gear saved her life.

** Even before you become a Witch, there is still some opportunity for horror. The Soul Gems in question? [[SoulJar Their name is literal]]. Since your soul is outside your body, that essentially makes you a girly, sparkly [[OurLichesAreDifferent Lich]]. The girls find this out the hard way when Sayaka's soul gem is thrown too far away from her body, causing her to fall over dead until it is returned to her. She then considers herself inhuman and this accelerates her inevitable transformation into a Witch.]]

* Creator/DavidCronenberg's ''Film/{{Shivers}}''... and then Dr. Saint-Luke was Infected. Ironically, David Cronenberg considers this a ''happy'' ending, as he's said the Infected are happy and free of their inhibitions, and at the end they're about to share their newfound freedom [[UtopiaJustifiesTheMeans with the whole world]].

* ''VideoGame/EternalDarkness'': Anthony's chapter casts the hero as a Frankish messanger who intercepts a message intended to curse Charlemagne by exhausting the curse on himself first; his chapter is devoted to racing to defend Charlemagne while slowing succumbing to the corrosive curse though his efforts are futile. In Paul Luther's chapter later on, Anthony is encountered again, tragically having been turned into a zombie of Augustus Pious's dark god.

** ''VideoGame/BioShock2'' uses it for a few [[PlayerPunch nutshots on players]].[[spoiler: Remember Mark Meltzer? That badass protective father from the surface who comes to Rapture to find his daughter and manages to survive it? Yeah, he gets caught by Lamb and turned into a Big Daddy- one you'll have likely killed shortly before finding his last audio diary. And at the end of the game, you have to fight your VoiceWithAnInternetConnection, Augustus Sinclair, as a Big Daddy.]]

* In ''VideoGame/TheElderScrollsIVOblivion'''s "Shivering Isles" Expansion, you are summoned by Sheogorath, Daedric Prince of Insanity, to be his champion and defeat his other half. When you do, he rewards you by turning you into himself. Though it doesn't seem to affect the game much except at certain points you can go into Madgod Mode. Otherwise the game still plays out normally. Gone further in ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''; the Dovahkiin meets the new Sheogorath, who has at this point has fully transformed and seems to be a shell of his former self, though he isn't complaining. This is a first and only for Bethesda in which you actually meet the hero from a previous game.

** "[[Recap/DoctorWhoS31E4TheTimeOfAngels "The Time of Angels]]"/"[[Recap/DoctorWhoS31E5FleshAndStone Flesh and Stone]]": Cleric Bob is murdered by the Weeping Angel, who uses his nervous system to reanimate his consciousness to talk to the Doctor.

** [[Recap/DoctorWhoS26E4Survival "Survival"]] has this as the major plot point.
** [[Recap/DoctorWhoS31E4TheTimeOfAngels "The Time of Angels"]]/[[Recap/DoctorWhoS31E5FleshAndStone "Flesh and Stone"]]: Cleric Bob is murdered by the Weeping Angel, who uses his nervous system to reanimate his consciousness to talk to the Doctor.
** [[Recap/DoctorWhoS33E1AsylumOfTheDaleks "Asylum of the Daleks"]]: Oswin was a Dalek the whole time. She was only dreaming she was still human.
** [[Recap/DoctorWhoS39E4VillageOfTheAngels "Village of the Angels"]]: The episode's {{Cliffhanger}} involves ''the Doctor herself'' getting turned into a Weeping Angel.

* ''VideoGame/EternalEvil'' has an ending where Marcus decides to relinquish his humanity and become a vampire, after listening to the vampire lord's offers. Now that he's immortal, he gets to witness the purging and extinction of humanity in '''[[DistantFinale 2014]]'''.

* ''Film/NightOfTheAnimatedDead'': Like in [[Film/NightOfTheLivingDead the original movie]], when Helen goes down to the basement in the climax, she discovers that her daughter Karen has become a zombie, and is eating her father. [[spoiler:When Ben retreats into the basement, he kills Karen, and then looks over at Harry's body, which raises his head, and his hand, in Ben's direction.]]

* In the final scene of the movie ''Film/{{Deadgirl}}'', we find out that the main character has become a [[DoubleStandardRapeSciFi zombie]] rapist]] despite spending the entire movie trying to dissuade his friends from doing the exact same thing.

A popular variation of this is for protagonists to have this thrust on them as an EmergencyTransformation, and/or (attempt to) use HeroicWillpower to avoid the FaceHeelTurn frequently associated with this trope. If that works, the hero can use the powers [[CursedWithAwesome for the cause of good]]. Results of such attempts vary. It is also possible for this to happen to villainous characters. Depending on the villain and the type of transformation in question, results vary --even more than heroic characters-- but it can then result in a HeelFaceTurn. Or it could just be a (deconstructed) case of OneWingedAngel.

* This is the entire premise of the ''VideoGame/ResidentEvil'' fic ''[[https://www.fanfiction.net/s/10893368/1/Metamorphosis-and-Consequences Metamorphosis and Consequences]]'' - Leon and Helena and later Ada are infected and mutated into C-Virus B.O.W.s.

* In ''Fanfic/{{Respect}}'': This happens in a symbolic sense to [[Anime/SmilePrecure Yayoi]], who makes a [[DealWithTheDevil contract]] with [[Anime/PuellaMagiMadokaMagica Kyubey]] in order to stand up to the bullies that torment her. By the end, as Mami points out, she's become a villain, a "bully" herself, and being confronted with this sends her over the DespairEventHorizon. The trope then happens in a ''literal'' sense, as we see that Yayoi has transformed into Izabel, the Artist Witch from episode 10 of Madoka.]]
