* Same exact ending as above occurs in the 1970 film, ''Count Yorga, Vampire'', [[spoiler:where the leading female character turns into a vampire and lunges at the hero of the film just as he rescues her from the clutches of the vampire villain]].

This is related to HeWhoFightsMonsters, but it's more literal. It can very easily be a ShockingSwerve. Opposite of TomatoInTheMirror, in which case the main character ''was'' the monster all along. Contrast CantStayNormal. If this was a possible occurrence set up at the beginning of the story, it's then a DoomedProtagonist.

* The ending of ''30 Days of Night'' involves the hero, Eben Oleson, turning himself into a vampire to save his friends. This counts because the vampires invaded to feed, not to create new vampires and the humans (until that point) weren't interested in becoming vampires.

* In XMen, a few characters were anti-Mutant before the reveal that they were mutants themselves. IIRC, Elixir is one of these.
* It's been implied a few times that eventually, all the stress, strain and pressure of his life will cause {{Batman}} to snap eventually, and when he does, it's only a question of whether he starts killing heroes or villains. It's implied the line of Robins and Batfemales are there to help him cope.

* At the end of the ''30 Days Of Night'' movie, the protagonist [[spoiler: has to become a vampire in order to fight off the vampires that have been eating everyone. Long story short: the main character has very little time in which to fight and kill the vampire leader, before he himself becomes hungry for humans. he dies very shortly thereafter due to watching the sunrise with his girlfriend (so he'll die and not eat anyone).]]

* DavidCronenberg's ''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 [[spoiler: share their newfound freedom [[UtopiaJustifiesTheMeans with the whole world]]]].

* All the alternative endings of ''TheRuins'' show the FinalGirl succumbing to the evil [[spoiler: plant spores]] in some way, while it is suggested in the theatrical one.
* At the end of ''The Chronicles of {{Riddick}}'', Riddick [[spoiler: kills the Grand Marshall and becomes the new leader of the necromongers]], which was foreshadowed ''very'' strongly early on, [[spoiler: when Riddick is told that the Necromonger way was "You keep what you kill"]].

* At the end of {{Candyman}} the heroine becomes a Candywoman.
* At the end of Vampire Assassin, the protagonist becomes a vampire.
* ''[[FridayThe13th Friday the 13th]]: A New Beginning'' ends with the heavy implication that Tommy will become [[JackTheRipoff a copycat]] Jason Voorhees. [[AbortedArc He didn't]].
* Tough he wasn't really fighting aliens,the protagonist of ''{{District 9}}'' becomes one of them at the end.

* Blizzard seems to love the trope. At the end of ''{{Diablo}}'', the hero defeats the titular boss and jams its [[SealedEvilInACan soulstone]] in his/her own forehead to contain it. This results in [[spoiler:the hero becoming the new BigBad in ''Diablo 2'']].

* This happens in KnightsOfTheOldRepublic, after TheReveal; always for Bastila and optionally for the player.
* In the ''Possessed'' ending of ''SilentHill 3'' [[spoiler: Heather becomes demon-possessed, and kills Douglas]].
** In the [[MultipleEndings worst ending]] of ''Homecoming'', Alex becomes a Pyramid Head.
* ''{{Disgaea}} 2's'' HighOctaneNightmareFuel [[MultipleEndings worst ending]] features this. ''In spades''.
** To elaborate, if Adell has met the required conditions,[[spoiler: Rozalin, The ''real'' Overlord Zenon, will inform you that you too are her enemy. If you are victorious, Zenon's evil will consume Adell's soul. His first act as the new God Of All Overlords? To devour his younger brother and sister, bones and all]]. [[NightmareFuelUnleaded Cue crunching sounds]].
* The ''good'' ending of ''{{Eversion}}'' turns your character into [[spoiler:an EldritchAbomination just like the princess you're out to save]]. The bad ending has [[spoiler:you resisting this and getting eaten by the princess]].

**** Both endings of the game might be canon at the same time, as some of the NIS games, like {{Soul Nomad And The World Eaters}}, in which case it even is an esential part of the plot, show that the ''Disgaea-verse'' includes parallel timelines.

* The Bydo ''love'' pulling this on humanity's heroes in the ''{{R-Type}}'' series. It first happens in ''R-Type Delta'', if the player is piloting the R-13 Cerebrus--that particular fighter proves incapable of escaping the final level, and the Bydo exact revenge by converting the ship and its pilot into a tree-like Bydo. Then there's ''R-Type FINAL'' (where the converted R-13 also appears as a boss), in which one of the MultipleEndings leads to the player getting converted into a hybrid Bydo/human/R9-Series ... [[BiologicalMashup thing]] ... and is sent back to the ''first level of the game,'' fighting both the Bydo as well as its former comrades. (It's worth noting that at the start of the game, you can ''see'' your future Bydo self [[StableTimeLoop fly by at the very start of the level]]!) ''R-Type Command'' also pulls this ''on an entire human fleet'' at the end of the Human campaign--in fact, the player's character in the subsequent Bydo campaign is the former human commander. In both the case of ''FINAL'' and ''Command'', the player's characters ''have no idea that they're no longer human'' and can't understand why Earth's forces are out to get them.

** [[MyFriendsAndZoidberg And Sylvanas]].

* In Castlevania 64's Downer Ending, 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".
** In the [[{{Ptitle1btexpw9}} Chornicals of Sorrow]] games, Soma Cruz is trapped in the titular castle, trying to help prevent the resurrection of Dracula only to learn that he is the reincarnation of Dracula by the end of the first game.

* Not entirely sure if this counts, but in ''KingdomHearts'', Sora [[spoiler: [[HeroicSacrifice impales himself with Riku's Dark Keyblade in order to free Kairi's heart]], releasing her from her catatonic state. In the process, he becomes a Heartless ''and'' creates two Nobodies: Roxas (himself) and Naminé (Kairi). Of course, it doesn't stick, Kairi leads him back to the light, but in ''KingdomHeartsII'', you will occasionally turn into Anti-Sora when activating a Drive Form. Perhaps a nod to his stint on the DarkSide?]]
** This is actually confirmed that Sora has that form because he [[spoiler: became a Heartless for a time.]] It has also been described as [[spoiler: "The closest Sora has come to being a Heartless again."]] Note that when you turn into [[spoiler: AntiForm]] in Halloween/Christmas Town, you gain a [[spoiler: Heartless]] Mask.

* ''Dead Space: Extraction'':[[spoiler: In the fist chapter, you play as one of the soon-to-be necromorphs and unknowingly kill all your comrades.]]
* Surprised no one mentioned the twist in ''Legacy of Kain: Soul Reavel 2'' where it turns out that [[spoiler: the soul reaver is in fact Raziel's soul, which was absorbed into the original blood stealing "Reaver" and driven insane from being trapped for hunreds of years.]] And that he is doomed to fulfill this fate over and over again [[spoiler: at least until Kain creates paradox and saves him... until Defiance when Raziel willingly becomes the soul reaver, purified of any corrupting influence.]] Of course this can also be called a TomatoInTheMirror.
** In true mind-breaking LegacyOfKain style, it's both. There's a TomatoInTheMirror BECAUSE John became a zombie at the end.

* Finn and Jake of ''AdventureTime'' are both turned by the end of "Trouble in Lumpy Space". [[IGotBetter They got better]].

** In the [[Ptitle1btexpw9 Chornicals of Sorrow]] games, Soma Cruz is trapped in the titular castle, trying to help prevent the resurrection of Dracula only to learn that he is the reincarnation of Dracula by the end of the first game.

** In the ChornicalsOfSorrow games, Soma Cruz is trapped in the titular castle, trying to help prevent the resurrection of Dracula only to learn that he is the reincarnation of Dracula by the end of the first game.

* The WhamEpisode in RedVsBlue: Reconstruction. Up until that point in the series, pretty much every problem that befell upon either the Red or Blue teams was caused by the Freelancers and their many AI. So naturally, it was a very shocking twist to find out [[spoiler:that Leonard Church was the original Alpha AI that had been split into all the other AI that the cast had been fighting throughout the entire series. On top of that, the director of Project Freelancer is the ''real'' Leonard Church.]]

** [[{{Nostalgia Critic}} "OF COURSE!"]]

* In Castlevania 64's Downer Ending, 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". So Yeah.

* Surprised no one mentioned the twist in ''Legacy of Kain: Soul Reavel 2'' where it turns out that [[the soul reaver is in fact Raziel's soul, which was absorbed into the original blood stealing "Reaver" and driven insane from being trapped for hunreds of years.]] Of course this can also be called a TomatoInTheMirror.

* Finn and Jake of ''AdventureTime'' are both turned by the end of "Trouble in Lumpy Space". TheyGotBetter.

* One could argue that Brad Pitt's character in ''{{Se7en}}'' has this happen to him, though it's forced by the antagonist.

* How much does Joe of ''TheLostRoom'' love his daughter? Well, after spending all the series [[GottaCatchEmAll trying to find the Object]] to rescue her from a NegativeSpaceWedgie, he becomes an Object to save her. That's right, he gives up being a human and becomes a sapient, mobile, indestructible and unaging ''thing.'' This is presented as a good thing however, despite the former Object/person/Occupant pretty much hating his [[strike:life]] existence.

* In the 1986 [[Twilight Zone]] episode "Monsters!", the presence of a (kind-natured) vampire in their neighborhood causes every normal person in suburbia to temporarily mutate into a pack of gruesome monsters that kill the vampire - afterwards, they're horrified at the murder, never realizing that they were the monsters.

** In addition to being a beautiful movie over all, [[spoiler: that last, beautifully shot scene rung true and truly sad.]]
** [[YourMileageMayVary Or pure]] {{narm}}.
