->''"My very existence is a threat to all life to the universe! And I don't even know it!"''
-->-- '''Beth Tezuka''', from a ''WebAnimation/BravestWarriors'' production image

When TheHero is in charge of preventing TheEndOfTheWorldAsWeKnowIt, imagine his surprise when he finds out the threat comes not from some EvilOverlord, but from one of his [[TrueCompanions friends or family]] destined to bring about the end of the world. The reasons for this can vary.

Maybe they have [[InTheBlood inherited]] a form of EnemyWithin or SuperpoweredEvilSide capable of destroying worlds, or have been [[DemonicPossession possessed]] by an EldritchAbomination. Most heart wrenchingly, they are completely innocent yet their mere ''existence'' acts as a ButterflyOfDoom that can destroy the CosmicKeystone. Either way, they're going to somehow bring about the apocalypse in some form BecauseDestinySaysSo.

Needless to say, the [[PragmaticVillainy villains]] (and [[WellIntentionedExtremist certain heroes]]) who realize this want to nip this in the bud by killing them. Of course, seeing as that person is one of their TrueCompanions (usually a LoveInterest), the heroes say ScrewDestiny and try to protect the chosen one from others and potentially, [[DrivenToSuicide even themselves]]. Then again, [[DarkMessiah some villains]] ([[FallenHero and certain heroes]]) may well ''[[WoobieDestroyerOfWorlds want them]]'' to destroy the world, and kidnap them in order to {{brainwash|edAndCrazy}} or [[HumanSacrifice sacrifice]] them in a manner that kick starts the apocalypse. In which case the heroes have to find a way to stop the world ending and save their friend... and both [[ScyllaAndCharybdis may be mutually exclusive]].

Sadly, because YouCantFightFate these attempts to prevent the cataclysm may become [[SelfFulfillingProphecy self-fulfilling]] because PropheciesAreAlwaysRight (in such a case, it's a DownerEnding). Optimistically, their friend's efforts and ThePowerOfTrust may embolden them to become an AntiAntichrist and successfully rebel against their destiny... even if it requires [[HeroicSacrifice the ultimate sacrifice]].

PropheticFallacy may also be a cause for the villain's alarm, or maybe ThePowersThatBe were merciful.

This is more of a plot than a character (it could be either). Much like BarrierMaiden, this trope is open to both genders. See also/contrast BigBadFriend, SaveThisPersonSaveTheWorld and BarrierMaiden.[[note]]That trope is basically the inversion of this one. The Barrier Maiden's purpose is to ''sustain'' the world while the Apocalypse Maiden's purpose is to ''destroy'' it.[[/note]] May well become an AntiAntichrist.



[[folder: {{Anime}} and {{Manga}}]]
* Rei Ayanami from ''Anime/NeonGenesisEvangelion'', as part of an AssimilationPlot. She is unusual in that [[spoiler:she actually ''succeeds'' in obliterating all life on Earth]]. [[AssimilationPlot Sort of]]. [[MindScrew Maybe]]. [[GainaxEnding We think]].
** NGE also gives us a rare male example: Kaworu [[EnsembleDarkhorse Nagisa]]. Unlike Rei, [[spoiler:he chooses the HeroicSacrifice variant]]. And even then, Rei encourages Shinji not to go through with it, but he is adamant about wanting her to cause Instrumentality [[BreakTheCutie due to everything that happened to him up until then]].
*** Which ironically, implies that Shinji is the Anti-Christ. Makes a weird spin on the whole EverybodyIsJesusInPurgatory thing.
*** Well, his birthday is the sixth of June...
** In ''Anime/RebuildOfEvangelion'', [[spoiler:Shinji himself]] is this, complete with the remaining heroes debating whether to kill or not and the antagonists having him kidnapped to further their goals. [[{{Deconstruction}} This being Evangelion]], by the time that the third movie rolls around and most of the cast know... and have turned against him for reasons ranging between irrational hatred and pragmatic self-preservation (and in a few circles, Asuka and Misato were even slapped with Main/RonTheDeathEater treatment). It is to be noted that he [[UnwittingPawn never intended to destroy the world]] - both times that he brings on planetary-scale-devastation were set up by the [[GambitPileup scheming of the various antagonists.]] The first time, he was intending to save [[spoiler: Rei]], and accidentally set it off, the second time, he was told that the ArtifactOfDoom [[UnholyHolySword he was after]] [[TheCakeIsALie would undo the effects of the former event.]]
* In ''Manga/{{Naruto}}''; there are the two male versions of this; [[TheChosenOne Chosen Children]] [[MessianicArchetype Naruto]] and [[DarkMessiah Nagato]] who were destined to bring a new golden age to the world.....or bring it into complete and utter ruin; the latter took the second road at least until before he [[RedemptionEqualsDeath died]] while the former still remains the saviour...for now.
* In ''Anime/TengenToppaGurrenLagann'', [[spoiler:Nia turns out to be a virtual lifeform that acts as an agent for the [[BigBad Anti-Spirals]]]]. Played at its straightest when [[spoiler:she puts herself between the heroes in their GiantMecha and the keyhole that will allow them to take control of the moon and keep it from crashing into the Earth (said keyhole having a key that also happens to be a [[ThisIsADrill giant drill]])]].
** This is, not incidentally, the point where most first-time watchers start baying for the blood of the show's ultimate [[BigBad antagonists]]. Not because of TheEndOfTheWorldAsWeKnowIt - that's just what villains do, you can't ''really'' hate 'em for it - but for doing that to [[spoiler:the insanely {{Moe}} {{Woobie}} Nia]].
** [[spoiler:Cruelly played with in the ending where after [[StormTheCastle overcoming impossible odds and saving the entire galaxy]] from the Anti Spirals Nia fades away on her and Simon's wedding day - as a virtual lifeform created by the Anti Spirals, [[NoOntologicalInertia she can't exist without them]]. The poor girl survived until said wedding day ''[[PluckyGirl only out of sheer willpower]]''.]] Then again...
* Played with in ''Manga/TheLuciferAndBiscuitHammer''. The ApocalypseMaiden ''wants'' to cause the EndOfTheWorldAsWeKnowIt, and the [[AntiHero protagonist]] is helping her to accomplish that goal. [[spoiler:At least, that was his cover for almost the entire span of the series. Turn out he had been plotting to ''stop'' her since Day 1]].
* Hotaru Tomoe (Sailor Saturn) from ''Franchise/SailorMoon''. The Outer Senshi misunderstand her job thinking it is a bad thing (And confuse her with Mistress 9 who's possessing her and is TheAntiChrist) and try to prevent her from awakening. They fail and she explains her job is to serve as a reset button in the event that the bad guys win, allowing Moon to restore the world into its proper form. She doesn't get to destroy the world in the [[Anime/SailorMoon anime]] (she defeats the BigBad with Moon's help, then is reborn as a baby), but does in the [[Manga/SailorMoon manga]]; Sailor Moon restores it moments later.
* One of the main characters of ''Manga/BlueSeed'' gets this status near the end of the series...
* In ''Manga/MahouSenseiNegima'', [[spoiler:BigBad Fate Averruncus wants to erase Mundus Magicus and put its inhabitants into a LotusEaterMachine to keep them from disappearing when Mundus Magicus collapses on its own. And it turns out that he needs Asuna's AntiMagic abilities to do it]]. But in the end, [[spoiler:Fate and his group are defeated, and Asuna channels her powers through a WorldHealingWave instead.]]
* A major theme in ''Manga/MythicalDetectiveLokiRagnarok'', the reason most of the gods are trying to kill Loki is simply BecauseDestinySaysSo that he will destroy the world.
* In ''Anime/DigimonTamers'', [[spoiler:Juri Katou]] unwillingly becomes this for the BigBad after suffering from a ''massive'' BreakTheCutie moment.
* ''Anime/DigimonUniverseApplimonsters'' has a male example played at its straightest, Yuujin Oozora, or YJ-14, for being both [[TheHero The Hero's]] [[HoYay most treasured friend,]] and the [[BigBad Big Bad's]] creation that is made to serve his goal, resetting and controlling the world by turning all humanity into data. Not that he's willing to do those, of course. As a programmed android, he just can't resist his creator's wish that wants to gain control of him back, after long enough letting the main character has him as a friend. [[spoiler: While he does complete his job as ApocalypseMaiden, TheHero still wants to bring him back and restore the world. TheHero's determination interests the BigBad, and which then gives him a chance, by going through SadisticChoice.]]
* ''LightNovel/ScrappedPrincess'' is the obvious example - there, the main character, who is also the eponymous character, basically lives this trope. 99% of the world wants to kill her because she's destined to bring about TheEndOfTheWorldAsWeKnowIt, while the remaining percent wants to protect her because it's not HER fault. Resultantly, we've got both 'villains' who are really just scared people who are afraid to see their world collapse around their ears, or obeying orders from up on high... and REAL villains who are manipulating events for their own advantage, with complete disregard for the number of lives involved. Not to mention some of the 1% that help her are [[OmnicidalManiac pretty crazy]].
** Unlike the other series, the TheEndOfTheWorldAsWeKnowIt in this series is a GOOD thing.
* ''LightNovel/{{Slayers}}'', more specifically the second season (NEXT), may have fallen into this. When the team is facing the BigBad, Lina wonders if she should fight it because a) she doesn't think think she can possibly win and b) the only way she can win is with a DangerousForbiddenTechnique called Giga Slave that has a high chance of wiping out all existence. At this point, some of the members have to warn her that under certain circumstances, they may have to fight her. Turns out that the [[ManBehindTheMan true]] BigBad wants her to use the technique and tries to force her into it, because the ultimate goal of demons is to return the universe to empty blackness.
* ''Anime/SonicX'': [[spoiler:Cosmo]] turns out [[spoiler: to have been implanted with an audio and visual tracking device allowing the BigBad to see every single move she makes, thus leading them right to the good guys the whole time, basically dooming their every effort. [[TheWoobie Cosmo angsts about this considerably]], [[WellIntentionedExtremist Shadow]] just outright wants to kill her and even just removing the transmitter would blind and deafen her permanently, and everyone else rallies to her side deciding to [[TakeAThirdOption defeat the Big Bad]] even ''with'' the transmitter]]. [[spoiler: She still dies, in an HeroicSacrifice]]
* Hayate Yagami of ''Anime/MagicalGirlLyricalNanohaAs'', the latest friend of Nanoha's group during that season who also happened to be the latest master of the [[ArtifactOfDoom Book of Darkness]], a rather hazardous title considering how all previous masters died blowing up their worlds after the book possessed them and [[OmnicidalManiac went omnicidal]]. Much discussions about the cruelty of fate were had.
* Elie [[spoiler: alias Resha Valentine]] in ''Manga/RaveMaster''.
* Lucy from ''Manga/ElfenLied'' definitely fits this, [[EnemyWithin inner demon]] style. Eventually, [[spoiler: her Lucy/Kaede and Nyu personalities [[ICannotSelfTerminate beg Kouta to kill her]] now that her homicidal Diclonius instincts personality has finally taken over and started [[OneManArmy killing humans everywhere on the world at rates rivaling WMDs]] in an attempt to [[ApocalypseHow wipe out humanity]] to conquer the world for her species]].
* In the second season of ''Anime/DarkerThanBlack'', [[spoiler:Yin ("Izanami")]] ends up as one of these. Although the GainaxEnding and MindScrew make it hard to say for sure exactly what happened, it appears that [[spoiler:she was possessed by an EldritchAbomination but managed to suppress it for a while; when it woke up, she causes Contractors to commit suicide and attempts to reach [[EldritchLocation Hell's Gate]]. When she's met there by her counterpart "Izanagi" (Shion), she can cause the Gate to open, which, whatever it does, can't possibly be good given what we've seen of the place and some very apocalyptic-sounding prophecies from Amber. Hei spends most of the season trying to find her and [[ShootTheDog kill her]] to prevent this. He ends up basically exorcising her instead]].
* In a rather weird example, ''LightNovel/HaruhiSuzumiya'' can bring about the end of the world on a whim, and she does not know it. Everyone tries to keep her pretty happy and/or occupied, so her subconscious doesn't act on such things. Although Kyon tends to push this when he gets annoyed at her.
* In ''VideoGame/GateKeepers'', [[spoiler: Ruriko Ikusawa]] is briefly turned into this by the enemy when she becomes BrainwashedAndCrazy by the BigBad. [[spoiler: Shun Ukiya manages to talk her out of it, though]].
* Mayo Sakaki from the 3rd ''Manga/FushigiYuugi'' OVA. She very nearly destroys the entire Universe of the Four Gods just to get a fairy-tale ending with Tamahome. [[spoiler: Little does she know it's a sort of BatmanGambit deployed by Miaka to save the Universe of the Four Gods!]]
* In Creator/{{CLAMP}}'s ''Manga/{{X1999}}'', [[spoiler: Kamui and his best friend Fuuma]] are "twin stars" - one destined to save the earth, the other destined to destroy it. [[spoiler: Kamui]] chose to save the world, so [[spoiler: Fuuma]] got stuck with the role of destroying it, along with gaining a evil personality change to go with his FaceHeelTurn.
** To clarify, [[spoiler:Fuuma is destined to fill the empty seat left when Kamui picks his side. If Kamui were to join the Dragons of the Earth, Fuuma would go to the Dragons of the Heaven. But Kamui chooses to join the Heavens, so Fuuma goes to the Earth. Either way, destiny is skewed toward the Dragons of the Earth winning. Meaning that there will be a catastrophe that wipes out mankind, but other life goes on. The only version where this really means that Fuuma is a SlasherSmile maniac is the animated movie, though. Otherwise, he's still as GrayAndBlackMorality as everyone else in the series]].
* [[spoiler:The main character, Juliet Fiamatta Asto Capulet]] in ''Anime/RomeoXJuliet''.
* In ''Roleplay/RecordOfLodossWar'', it is revealed that [[spoiler:Little Neese, the girl that spends most of the first part of the show sleeping in the arms of several of the older characters, or as an [[ShrinkingViolet extremely shy]] [[MysticalWaif teenage priestess]] in the second]] is one of the three key objects for a ritual that will destroy the entire continent. As there's no place where she would be safe from being kidnapped by the evil sorcerer ''and'' she has known her condition as an ApocalypseMaiden ever since she was young, she rather takes her chance and tries [[StormingTheCastle to take him down before he finds her]].
* [[spoiler:Brief]] in ''Anime/PantyAndStockingWithGarterbelt'', [[spoiler:whose ''penis'' is the key to Hell!]]
* Played straight with Chise from ''Manga/{{Saikano}}''.
* ''Anime/{{Macross}}'':
** In ''Anime/MacrossZero'', Sara Nome is the priestess of Mayan Island; this means that [[spoiler:she has the power to control the Bird-Human, an ancient Protoculture biomecha designed to destroy humanity if their warlike tendencies are deemed to be uncontrollable]].
** ''Anime/MacrossFrontier'' has [[spoiler:Sheryl and then Ranka]] engineered to affect the Vajra with their singing and keep them off the BigBad until she can use [[spoiler:Ranka]] to pull off an AssimilationPlot for the entire galaxy. Also, Ranka's pet Ai-kun counts to some extent since the cute little critter is [[spoiler:eventually revealed to be a larval Vajra which takes Ranka back to the Vajra homeworld for use by the BigBad]].
* Miharu from ''Anime/{{Gasaraki}}'' seems to be one. [[spoiler: In the end, the ''real'' one is Yuushiro's little sister Misuzu]].
* ''Manga/OnePiece'': Luffy actually became this in the Fishman Island arc (or at least was believed to be one), where the fortune teller Madame Shirley foretells a boy with a Straw Hat who will spell doom for Fishman Island.
** And near the end of that arc, we have [[spoiler:Shirahoshi]], who is said to have a power able to destroy the whole ''world'' and is mostly unaware of it. Past uses of this power back up this claim pretty well.
** [[spoiler:Robin]] is also a potential ApocalypseMaiden, as she could allow the recreation of an ancient WeaponOfMassDestruction [[spoiler:because she's the only one who can read Poneglyphs it may be written on.]] It's part of the reason the World Government considers her very existence a crime. [[{{Hypocrite}} Even though they're trying to make that same weapon themselves.]]
* ''Manga/FairyTail'' gives us [[spoiler:Mavis Vermillion]], seemingly the series' BigGood, in a huge plot twist revealed in the final arc of the series. At first it seems she's [[spoiler:a CuteGhostGirl, being the deceased founder of Fairy Tail who was so powerful that she somehow transcended ''death itself''. It later turns out that as a result of an extremely dangerous spell she learned from the series' BigBad, Zeref, Mavis got slapped with the [[FateWorseThanDeath Curse of Contradictions]], which damns the condemned to an [[CompleteImmortality immortal]] life of loneliness via an InstantDeathRadius that kills anyone they ever come to care about. It wasn't until ''after'' she fell in love with Zeref, wanting to give EternalLove a shot to give them both a chance at happiness in their incredibly lonely and miserable existences that Mavis seemingly dies (except [[OnlyMostlyDead not really]]), and Fairy Tail's Second Master, Precht, discovers that deep inside of Mavis lies [[MacGuffin Fairy Heart]], a.k.a. Lumen Histoire, a potential source of infinite magic (and [[GoMadFromTheRevelation loses his mind]] as a result). Which Zeref then wishes to use to power a universal ResetButton to RetGone the current universe and stop himself (and by extension, Mavis as well) from ever getting cursed in the first place.]] Oops.
* ''Anime/PuellaMagiMadokaMagica'': ''[[spoiler: The title character]]''. [[spoiler:For the exact same reasons that she's the MacGuffinSuperPerson]]. [[GenreDeconstruction It's that kind of show]].
* [[spoiler:Mana/Inori]] in ''Anime/GuiltyCrown''.
* In the ''Manga/AhMyGoddess'' movie, we have [[spoiler: none other than ''Belldandy'' herself. With a good chunk of her memories gone, her heart in great turmoil due to believing that DarkMagicalGirl Morgan has won Keiichi over ''and'' TheVirus invading her body, the AntiVillain Celestine uses her to hack into Yggrasil's system and try resetting both Yggrasil and the Earth to wipe away all suffering...]]
* ''Manga/PandoraHearts'' has the Children of Misfortune, [[spoiler:who all turn out to be tragic subversions. The Jury, beings who have done their best to pre-plan every event in every world to create the best 'stories,' created the Baskervilles to act as their enforcers against [[YouCantFightFate any possible]] [[SpannerInTheWorks spanners in the works]]. Since the Children of Misfortune were abnormal and unpredictable beings born at the whim of [[SentientCosmicForce the Core]] and naturally ImmuneToFate, they were the main targets. Due to situations suspicious in hindsight, these Children were often born as close family members of the Baskervilles, but this did not save them from being [[HumanSacrifice ritualistically executed]] in [[SarcasmMode celebration]] every time a Baskerville heir came of age. To be fair, the Baskervilles had been raised on the belief that the Children of Misfortune were [[ApocalypseMaiden too dangerous to be allowed to live]] for ''centuries,'' and the Jury fed into the Baskervilles' own self-importance by glorifying their job as critical to the survival of the world. To be unfair, killing one of these Children caused a series of events that nearly ended the world for real.]]
* In ''Anime/ThisUglyYetBeautifulWorld'', Hikari is [[spoiler:the AnthropomorphicPersonification of Extinction turned into an amnesiac human girl.]]
* In ''Anime/YuGiOhArcV'', it turns out that [[spoiler: Yuya, Yugo and Yuto]] cross this trope with AntiAntichrist. These characters were ''supposed'' to become violent, dangerous duelists who wanted only destruction, but all turned out to be decent people. Thus, the person who set them up as [[AntiChrist Anti Christs]] in the first place has begun forcing them to carry out his apocalypse plan [[SuperpoweredEvilSide via possession.]] [[spoiler: The fourth counterpart, Yuri, is a straight AntiChrist, and if he manages to [[YourSoulIsMine absorb the other three]] [[AGodAmI he'll become a god]] [[ApocalypseHow and destroy the multiverse.]]]] As long as these characters exist, it's only a matter of time before the apocalypse gets kicked off.

[[folder:Comic Books]]
* The eponymous character of ''ComicBook/{{Hellboy}}'' is prophesied to bring about the end of the universe. But being the AntiAntichrist, he's not on board with all of that malarkey.
* ComicBook/{{Raven}} from ''ComicBook/TeenTitans'' is the daughter of the demon Trigon. She was conceived specifically to destroy the world.
* ''[[Comicbook/XMen Uncanny X-Men]] #137'', "The Fate of the Phoenix". The Phoenix Force, pretending to be ComicBook/JeanGrey, was so powerful she could no longer control it, and became the Dark Phoenix, risking the destruction of the universe. She eventually made a HeroicSacrifice to end the threat. It gets retconned back and forth all the time whether it was actually Jean or the Phoenix Force pretending to be Jean who did this, but it fits the trope either way.
** In at least one ''ComicBook/WhatIf'' issue, the HeroicSacrifice doesn't happen and Dark Phoenix ''does'' [[ApocalypseHow destroy the universe]].
* Also done with Colossus in Whedon's run on ''Astonishing X-Men: the [[MadOracle Augurs]]'' of a [[PlanetofHats Planet Of]] {{Blood Knight}}s called Breakworld predict he will destroy the planet, so they try to kill him in various ways, starting at developing a mutant "cure" and ending in blowing Earth to vapor. Fortunately, though an organization of WellIntentionedExtremist SpacePolice are not exactly on Colossus' side, the whole "kill Earth to kill mutants" thing has them pretty pissed off - they're not interested in killing Colossus, because if they can't make the bad guys quit trying to kill Earth, they can have Colossus kill them all. Pragmatism at its best/worst.
* Comicbook/{{Gambit}} of Earth616 was also fated to destroy the world by losing control of his Omega-level mutant powers and cannibalizing the energy of the whole planet, and in many universes he already had. In fact, everything that happened in his life before X-Men was the result of an alternate universe version of him manipulating him into going back in time and arraging things so that the events surrounding his prophecy would come about sooner. Everything from the Thieves Guild's allegiance to the immortal Candra, to Mr. Sinster's shapeshifting powers, to his own father adopting him were because another version of himself (powerful enough to single-handedly destroy the Phoenix) had already become a [[PlanetEater World Eater]] and was trying to stop it from happening in other universes.
* Alan Moore's ''ComicBook/{{Promethea}}'' is all ''over'' this.
* ComicBook/CaptainAtom in ''Captain Atom: Armageddon'' discovers that ''he'' is going to destroy the Wildstorm universe if he stays there, and that he also can't leave, ''and'' that if he dies, the destruction will happen instantly. [[spoiler:In the end, [[DeusExMachina Nikola cures him]] and sends him home. Then ''she'' destroys the universe. But then she remakes it]].
* Played with in ComicBook/LesLegendaires during the Anathos Cycle; the story starts with the protagonists learning that one of them is gonna serves as a host for the reincarnation of a OmnicidalManiac GodOfEvil known as Anathos. When they finally find out which one of them it is, it turns out to be Shimy, the group's elf. Team Leader Danael then pull out a BatmanGambit to prevent Anathos from reincarnating into her... only to end up OutGambitted by the God, who turns out to have planned this and reincarnate into ''him'' instead.
* In ''ComicBook/TheSandman'', [[spoiler: Rose Walker]] is a variation; she is a "vortex", whose existence causes the barriers between different people's dreams to break down, which drives them mad in the short term, and since dreams have the power to literally shape reality, she would ultimately destroy the world. The damage she could do is so serious that stopping a vortex is the only situation where Morpheus is allowed to actually kill a mortal. He states that the last time he didn't stop such a vortex, it brought about the end of an entire planet.
* The ComicBook/IncredibleHulk can turn into this as of Comicbook/WorldWarHulk, where it's revealed that if gets angry enough, his strength becomes too much for him to control and will cause devastation that can wipe entire countries simply through his footsteps and his voice destroys entire cities.
* This is essentially what happened to ComicBook/IllyanaRasputin in ''ComicBook/{{Magik}}''.

[[folder:Fan Works]]
* [[Manga/LuckyStar Kagami Hiiragi]] in ''FanFic/StarsAbove''. [[spoiler:Her body contains a [[Anime/PuellaMagiMadokaMagica Demon]] that can potentially destroy the Multiverse. She's also a BarrierMaiden... it's complicated.]]
* In the ''Fanfic/PonyPOVSeries'' we have [[spoiler:[[TomatoInTheMirror Twilight herself]] in Dark World. The true BigBad is Twilight's [[FutureMeScaresMe potential future self]] [[SuperpoweredEvilSide Nightmare Paradox]], who's trapped Discord in a GroundhogDayLoop for several hundred million years, with her goal being for Twilight to become her and then continue the loop, [[OmnicidalManiac destroying Dark World]] in the process. Twilight, quite naturally, rebels upon realizing this.]]
* In ''Fanfic/AnExtendedPerformance'', Princess Celestia fears that her younger sister Princess Luna may be this: if she isn't stopped, she will freeze the entire world with the TheNightThatNeverEnds. The problems are that Nightmare Moon is hideously ''powerful'', and Luna is the pony whom Celestia loves most of all in existence.
* [[spoiler: Shinji]] in ''Re-Take'' when revealed to be [[spoiler: an angel]]. Much like [[spoiler: Kaworu]] in the canon series, his existence leaves the possibility for the Third Impact to occur [[spoiler: in the alternate timeline he's in]] so he makes a HeroicSacrifice to prevent it.
* In the universe of ''Fanfic/TheBridge'', it turns out the Alicorns are this in a sense: [[spoiler: [[GodOfEvil Grogar]] was imprisoned by [[GodOfGood Harmony]] and while she naturally is not going to willingly release him, Alicorn Magic will work just as well to break his seal and other than Harmony seems to be the only thing that can. Given Grogar one of the [[PhysicalGod three most powerful beings]] in the entire story (matched only by Harmony and [[BigBad Bagan]]), this would be ''very'' bad. Especially if, as shown in Empress Flurry Heart's BadFuture, [[EvilVsEvil he and Bagan go to war with one another]] as Chrysalis predicts they will.]]
* [[spoiler:Elsa]] and [[spoiler:her alternate universe counterpart Iris]] from ''Fanfic/PerfectDiamondWorld'' are unknowingly half-god through their parents. They were destined from birth to bring the end of the world through [[spoiler:an ice age]], however their parents loved them too much to allow them to fulfil their destinies.

* In ''Film/{{Nightwatch}}'', the center of a coming apocalypse causing storm is a seemingly normal InnocentBystander. As the story goes on, we discover she is an Other (basically a witch) who is riddled with guilt over manipulating her mother into rejecting a life saving kidney transplant by revealing she was the donor. The spiraling guilt would have destroyed the world had Anton not talked her down (er, up?) from her depression. In the process, he gained a love interest for the next movie who was also [[spoiler:one of the two most powerful Others in existence. This is (somewhat) subverted in the novels. The apocalypse was actually a feint by The Dark Side to convert her, rather than being caused by her own actions]].
* ''Film/{{The Haunting of Molly Hartley}}''.
* This is the entire plot of the movie ''Film/{{End of Days}}.''
* ''Film/{{Ghostbusters 1984}}'': "Take me now, subcreature."
* The 1968 horror flick ''Film/RosemarysBaby'', based on a book by the same name. In fact, this is the entire point of the book/movie.
* In ''Film/TheSeventhSign'' Abby discovers that her child is destined to be born without a soul as the Guf (Hall of Souls) is empty. When she gives birth it will trigger the End Days, [[spoiler:but she ultimately averts this by sacrificing her own life to refill the Chamber]].

* [[{{Tykebomb}} Coin]], from Creator/TerryPratchett's ''Literature/{{Discworld}}'' novel ''Discworld/{{Sourcery}}''. Prophecy states that the existence of a [[PersonOfMassDestruction sourcerer]] will mean the end of the world, and it's stated that the prevention of such a birth was the original reason for the celibacy of wizards. Of course, someone always has to go and [[WoobieDestroyerOfWorlds do]] [[RoaringRampageOfRevenge something]] [[LoveMakesYouDumb stupid]]...
* Cyradis in ''Literature/TheMalloreon'' -- arguably, she wasn't going to destroy the world as such, but had she chosen [[spoiler: Geran over Eriond]] then the world would have been thrown into evil, via [[spoiler: Geran- Garion's son]].
* In ''Literature/PercyJacksonAndTheOlympians'', the Olympians discuss killing him -- to his face! -- because he ''might'' be a dangerous prophecied-of character.
* The ''Literature/ChroniclesOfNick'' is all about making sure Nick doesn't become the pure evil he was destined to be.
* In ''[[Literature/HisDarkMaterials The Amber Spyglass]]'' the priests send an assassin to whack smartass kid Lyra because it is prophesied that she will be [[spoiler:'''the new Eve''']] and bring about a new fall of Man. Just one of the many reasons why there'll never be any sequels of ''Literature/TheGoldenCompass''...
* In Nick Kyme's ''TabletopGame/{{Warhammer 40000}}'' novel ''[[Literature/{{Salamanders}} Firedrake]]'', it is established beyond a doubt that Dak'ir is the person prophesied to destroy the planet. [[spoiler: They imprison him while deciding whether to kill him, at the end]].
** To clarify, Dak'ir is prophesied to either destroy or save the Salamanders' homeworld, Nocturne. This gets resolved in the third novel of the Tome of Fire trilogy. [[spoiler: He saves the planet, though he also comes damn close to destroying it.]]
* A variant in ''Literature/{{Ravenor}}'', where [[spoiler:Carl is the prophesied host of the demon Slyte, who is set to bring about unimaginable destruction, but nobody realizes it until it's too late to save him]].
* Garth of ''The Lords of Dûs'' trilogy was destined to bring about the Age of Destruction by taking up the sword of Bheleu. By doing so, he also started the clock on the Age of Death, said to be the end of Time itself. Turns out [[spoiler:[[DeathOfTheOldGods it was only the God of Time dying; the world went on without him]].]]

[[folder:Live Action TV]]
* In ''Series/{{Smallville}}'', [[spoiler:Chloe Sullivan]] becomes this when she is possessed by ComicBook/{{Brainiac}}. She hacks every computer and hypnotizes half the world, intending to download all information before making Doomsday destroy what is left. The Legion arrives and prepares to kill her as they think it is the only way to get rid of Brainiac for good, but [[TheCape Clark]] convinces then to figure out a way [[ThouShaltNotKill without killing her]].
* ''Series/{{Supernatural}}'', with Gordon (and associates) trying to kill Sam before he can go bad and lead demon armies to conquer the world.
** Gordon isn't the only one who has it in for Sam. His own Dad was afraid killing Sam might be necessary some day.
** Even Sam thinks his own death might someday be necessary. He made Dean promise to kill him if he ever went bad, and in Season Five he even swore to [[spoiler: Lucifer]] that he'd kill himself before giving in. [[spoiler: [[BackFromTheDead Not that suicide would do any good]]]].
*** But then the angel [[spoiler: Anna]] says no problem, they'll just[[spoiler: kill Sam and prevent Lucifer from bringing him back to life by scattering Sam's molecules throughout the entire universe. [[ICannotSelfTerminate Apparently not even this will work]]]].
** And in an actual ''literal'' example, [[spoiler: Lilith]] is literally the final seal to release the apocalypse. Of course, Sam doesn't find this out until he realizes that maybe [[IdiotBall the tortured demonic soul of a former witch who got him hooked on demon blood might not be entirely invested in his best interests]].
*** In his defense, he thought it was okay to believe Ruby about Lilith since even the [[spoiler:[[LightIsNotGood ANGELS]]]] said that they agreed with her.
* Dawn in ''Series/BuffyTheVampireSlayer'' season 5. True to form, Buffy promises to protect her at all costs, even if it means the end of the world.
* In ''Series/{{Angel}}'', although no one realizes it until after it's already done, Connor and Cordelia are a matching pair of these; both are needed to bring forth [[WellIntentionedExtremist Jasmine]].
* This appeared to be Sofie's role in ''Series/{{Carnivale}}'', but the show ended before they could really explore it.
* ''Series/StargateSG1'' had this as well. When Hanka is wiped out by Nirrti, the team finds a sole survivor: a little girl by the name of Cassandra. Later it turns out that [[WhyAmITicking her body contains a globule of naquadah that has attracted all the potassium in her body]] and can cause cardiac arrest if someone attempts to remove it. Why is that a problem? Stargates contain over 29 tons of Naquadah. Naquadah reacts to potassium [[NukeEm violently]].
%%* ''Series/StarTrekTheOriginalSeries'': Edith Keeler. Damn it.
* ''Series/KamenRiderBlade'': Whichever [[MonsterOfTheWeek Undead]] is the last one standing at the end of the Battle Royale wins his or her species the right to rule over Earth as the dominant species. If the [[PlayingCardMotifs Joker Undead]] wins, however, the world ends. Specifically, [[spoiler:[[ZergRush an infinite horde]] of roach-like monsters appears and slaughters all life on the planet.]] [[spoiler:In the final arc, [[TheHero Kenzaki]] turns himself into a second Joker by over-using his SuperMode, putting the Battle Royale into a permanent stalemate.]]
** In ''Series/KamenRiderDecade'', the title character is referred to by several others as the Destroyer of Worlds. Late in the series you find out why: [[spoiler:His attempts to help repair parallel worlds [[NiceJobBreakingItHero unwittingly caused them to start merging and destroying each other]].]]
* In ''Series/PrettyGuardianSailorMoon'', [[spoiler: Usagi]] of all people, because of her [[spoiler:[[SuperpoweredEvilSide Superpowered]] LoveMakesYouEvil [[SuperpoweredEvilSide Side]], Princess Serenity]].
* ''Series/TheXFiles'' has this at least three times: the people in the snake church [[spoiler: rape and impregnate]] their leader's daughter with [[spoiler: some sort of anti-Christ]], both main wives and all past ones in "Terms of Endearment" [[spoiler: against the demons will - he was just trying to have a normal family]], and [[spoiler: Scully herself]] in a season 9 episode. The worst part of that last example is that [[spoiler: Scully is pregnant with William at the time, searching for a lost Mulder]], and just getting used to a newly-added Doggett.
* ''Series/PowerRangersSamurai'': This was the purpose for which Serrator turned Deker into a half-Nighlok, so that he could split the Earth open and completely drown it in the Sanzu river. The ''Series/SamuraiSentaiShinkenger'' version was a bit different, [[ShotForShotRemake unusual for that season]].
* Parodied in ''Series/BabylonFive'', Ambassador Mollari calls his three wives [[HorsemenOfTheApocalypse Pestilence, Famine, and Death]]. FridgeBrilliance when you consider that Mollari is [[spoiler: himself going to act as the fourth Horseman of the Apocalypse ''by starting a War''.]]
* In ''Series/{{Misfits}}'', [[spoiler: Nadine]] is this. She has the ability to bring The Four HorsemenOfTheApocalypse, and the only way that they are stopped is by killing her.
* Peter Bishop in ''Series/{{Fringe}}'' - the machine which could save or destroy both worlds is tied directly to him, not to mention that the hostilities between the two parallel Earths was started over him.
* On ''Series/PennyDreadful'', Vanessa Ives' supernatural abilities make her the target of various evil entities that believe her to be the reincarnation of the [[Myth/EgyptianMythology goddess Amunet]], the "Mother of Evil", whom they can use to start the apocalypse. Season 2 expands on this, revealing that when Lucifer was cast down to Hell, another FallenAngel was cast down to Earth, becoming [[MonsterProgenitor the first vampire]]; these two have [[EvilVersusEvil been in competition with each other]] ever since to find Amunet, as her power will allow the one who possesses her to break free of their imprisonment and seize control of Heaven from God, plunging the world into darkness.

* A major theme in Luca Turilli's album ''Prophet of the Last Eclipse'', particularly the song ''Demonheart''.
* Miriam Natias in the Music/KingDiamond {{concept album}} ''Music/{{Abigail}}''. Her soul is possessed by the titular [[FetusTerrible demon fetus]], and TheHero is told to kill her to prevent its resurrection.

[[folder: {{Mythology}} and {{Religion}}]]
* Shiva is said to dance the dance that creates, sustains, and destroys the universe all the time. However, it is specifically noted that he does this when his wife, Sati, sets herself on fire after being insulted (by her father) for marrying Shiva in the first place. It took Vishnu's discus cutting up Sati's body to stop Shiva from completely destroying the world. Similarly, Shiva acts as a BarrierMaiden when his wife in another form, Kali, goes on rampages.
* Oddly enough, ''UsefulNotes/{{Jesus}}'' according to Christian belief. His Second Coming in the Literature/BookOfRevelation foretells TheEndOfTheWorldAsWeKnowIt. [[SubvertedTrope However]], it's ultimately TheAntiChrist (who isn't in Revelation but is assumed by many to be a figure seen in that text, the Beast from the Sea) who brings about the End of Days.

[[folder:Tabletop RPG]]
* ''MagicTheGathering'' has Selenia and her correspondent (but not legendary) card, [[http://magiccards.info/ap/en/38.html Desolation Angel]].

[[folder:Video Games]]
* [[spoiler:Shana]] from ''VideoGame/TheLegendOfDragoon'', along with [[spoiler:all the moon children that Rose continued to kill every time one was born]]. The prophecy didn't come to pass because [[spoiler:BigBad Melbu Frahma [[NiceJobFixingItVillain made himself the next moon child]], effectively saving Shana from her role in destroying the world and giving the rest of the party [[DidYouJustPunchOutCthulhu a target they could beat down]] [[DebateAndSwitch without feeling bad about it]] ]].
* Princess Elise in ''VideoGame/SonicTheHedgehog2006''. [[spoiler:Iblis, the immortal fire monster, is sealed inside her and will be released to destroy the world if she cries]].
* Another example might be ''VideoGame/DevilMayCry 3''. It turns out that everyone involved (except [[ChessMaster Arkham]], who's orchestrating it all) is required to open the gates of hell, meaning that if any of them had died before then, hell can stay closed forever. Of course, it was prophesied that the Sons of Sparda would save the day, so it may be a subversion (odd in that the demons seem have it out for them)
* In ''VideoGame/{{Loom}}'', the Elders try to stop the player character from destroying the world. [[spoiler:They fail. NiceJobBreakingItHero]].
* In ''VideoGame/CastlevaniaDawnOfSorrow'', the main villain Celia Fortner seeks to revive Dracula.
** Oddly, this is a twisted example. Celia's cult, unlike Graham's from ''VideoGame/CastlevaniaAriaOfSorrow'', worships ''God'', and they fear for the Light [[BalanceOfGoodAndEvil if there is no Darkness]]. Hence, they wish for a new Dark Lord only to cover their own asses.
* ''VideoGame/TalesOfSymphonia'' plays with this. [[spoiler: To Sylvarant, Colette is the [[TheMessiah Messianic]] BarrierMaiden. But to Tethe'alla she is this trope.]] Finding that out is what makes the main party decide to ScrewDestiny and TakeAThirdOption. Helps that the BigBad is behind the whole corrupt system, giving them a target to beat up.
* In ''VideoGame/FairyFencerF'', anyone who is a descendant of the Vile God (in other words, either Tiara or Bernard) could be used as a sacrifice to revive him. Bernard insists that a woman's blood must be used to awaken him, but in the Goddess timeline he tries to usurp the Vile God's power; in response, it kills him and uses him as its sacrifice.
* The reason why Richter's after Marta in ''VideoGame/TalesOfSymphoniaDawnOfTheNewWorld''. [[spoiler:He should have been more concerned with Emil]].
* The [[BecauseDestinySaysSo Score]] in ''VideoGame/TalesOfTheAbyss'' has [[spoiler: Luke fon Fabre]] ultimately be this. The prophesied [[spoiler: destruction of Akzeriuth]] is supposed to kick off a series of events that results in TheEndOfTheWorldAsWeKnowIt. The plot kicked off because [[spoiler: Van]] decided to make the world end on ''his'' terms and thus [[spoiler: created the replica of the original Luke fon Fabre to take the original's place.]] This instead ends up kicking off events that result in ''preventing'' the end of the world and the choice to ScrewDestiny by the main party.
* [[spoiler: Estelle]] in ''VideoGame/TalesOfVesperia''. [[spoiler:As a Child of the Full Moon she naturally disrupts the [[{{Mana}} Aer flow]] of the planet, making her very existence a huge contributor to the decay of both the world and the seal on an ancient EldritchAbomination]].
* Shirley from ''VideoGame/TalesOfLegendia''. [[spoiler:[[NiceJobBreakingItHero Great job taking away all her reasons for ''NOT'' wanting to destroy humanity, Senel]]]].
* ''VideoGame/{{Lufia}}'' has [[spoiler: Erim, the Sinistral of Death. Her very existence enables her fellow [[JerkassGods Sinistrals]] to keep coming back no matter how often they're defeated; unfortunately, this isn't exactly a power she has any ''control'' over. Oh, and she usually shows up in each game as a mysterious girl... including Lufia herself in the original game]].
* ''VideoGame/Persona2: Eternal Punishment'' has four of them: [[spoiler:Tatsuya Suou, Lisa Silverman, Eikichi Mishina and Jun Kashihara.]] If any of these four remember the previous reality, then [[BigBad Nyarlathotep]] will be able to start making rumours come true again, which makes the definition of "reality" rather tenuous at best. Should all of them remember, reality will entirely reset to its previous state, in which planet Earth no longer exists. The game starts when the first of these four remembers, and he spends the rest of the game trying to stop the others from doing so. [[spoiler:Eventually, Tatsuya manages to let go of his memories, and reality is set back to normal.]]
* ''VideoGame/{{Persona 3}}'' plays with this. [[spoiler: Ryoji, a human-Shadow hybrid who acts as a beacon to summon [[EldritchAbomination Nyx, the Queen of the Shadows]], to bring about TheEndOfTheWorldAsWeKnowIt. [[SubvertedTrope Subverted]] in that killing Ryoji will not stop Nyx, just slow her down for an unspecified length of time and ensure that the protagonists can't fight back against her when she comes]].
* In ''VideoGame/SuperPaperMario'', it's [[spoiler:Luigi]]. No, really. The curious thing is, [[spoiler:Luigi]] is also one of the [[TheChosenOne Heroes of Light]]. This particular ApocalypseMaiden has the power to save the universe... but also to destroy it.
** ''VideoGame/PaperMarioTheThousandYearDoor'' has the far more likely [[spoiler:Princess Peach]] as the apocalypse maiden. This makes TheReveal in ''Super Paper Mario'' all the more shocking since [[spoiler:Peach]] is actually in the game, and even helps out the heroes.
* In ''VideoGame/DawnOfMana'', UnluckyChildhoodFriend Ritzia accidentally becomes this because she gets [[GrandTheftMe possessed]] by SealedEvilInACan.
* In ''VideoGame/SilentHill3'', the Apocalpse Maiden is [[spoiler: the protagonist, Heather, whose memories and RealityWarper powers as Alessa are awakening and threatening to destroy the world by giving birth to the cult's twisted version of "God"]]. The heroes consider the possibility that the only way to save the world might be to kill her; one of them simply can't bring himself to do it, while another mistakenly thinks he's found [[TakeAThirdOption a third option]] that'll solve the problem. In the end, [[spoiler: the villain saves them the trouble by gruesomely taking on the role herself, and then getting consumed by the creation an imperfect "God" that can be defeated]].
* In ''VideoGame/FinalFantasyXIII'', generally anyone who has been branded a "Pulse l'Cie" will be given a Focus to become an Apocalypse Maiden (Ragnarok). Once branded they either have the choice of carrying out their Focus (destroy the world) or becoming a mindless monster if they refuse.
* A few examples from ''VideoGame/FireEmblem'':
** Tiki from ''VideoGame/FireEmblemShadowDragonAndTheBladeOfLight'' is an immensely powerful Manakete put into an enchanted sleep, for fear that she'll destroy the world by mistake. For a time, she's BrainwashedAndCrazy to work for the Dark Dragon.
** In ''VideoGame/FireEmblemGenealogyOfTheHolyWar'' we have Deirdre in the first generation, Julia and Julius in the second. [[spoiler:They're Deirdre's children by Arvis]]. Deirdre had been forbidden to meet any men for fear it would cause a catastrophe. [[spoiler:This is because she carries the blood of the dark god Loptyr, and if any child with major Loptyr blood is born they could serve as a vessel for his return--which is exactly what happens to Julius. Good thing that Julia was born with the Holy Blood needed to ''counteract'' that too.]].
*** Happens again in ''VideoGame/FireEmblemAwakening''. [[spoiler:But '''not''' to Tiki, actually! Turns out your player-created Avatar, whether a boy or a girl, is in fact of pure enough Grima blood to serve as a vessel for his return. Worked in the BadFuture timeline, but averting it in the present one is one of the drives of the story. Not to mention you can recruit [[SheIsAllGrownUp a teenager/adult]] [[OlderAndWiser Tiki]] as one of the TrueCompanions willing to help you fight against Grima. (And if your avatar's a dude, ''[[DidYouJustRomanceCthulhu he can romance and marry her too]]''.)]].
** In ''VideoGame/FireEmblemTheSacredStones'', [[spoiler:Prince Lyon of Grado]] gets possessed by the Demon King after he [[SealedEvilInACan breaks a Sacred Stone]] to get at its immense magical power. The Demon King is about as nice as his title would suggest and starts trying to fully escape so he can wipe out the continent, using the unfortunate victim as a vessel.
* Most of the ''Franchise/ShinMegamiTensei'' games have at least one Apocalypse Maiden, usually referred to explicitly as "The Maiden". Yuko Takao of ''[[VideoGame/ShinMegamiTenseiIIINocturne Nocturne]]'' is the most obvious; without her, [[WorldOfSilence Hikawa]] would not have been able to [[EndOfTheWorldAsWeKnowIt create the Conception]] that kick-starts the plot.
** Played in a slightly different way in ''VideoGame/ShinMegamiTenseiStrangeJourney''. The apocalypse is already underway; [[spoiler:Zelenin's]] role is instead to [[spoiler:redirect it, so that instead of the world being overrun by demons, it's an angel-regulated WorldOfSilence]].
* In the ''Franchise/BaldursGate'' series, it first appears that [[spoiler: the PlayerCharacter him-/herself, along with all the other Bhaalspawn]], is prophesied and destined to bring about not quite the EndOfTheWorldAsWeKnowIt but hell of a lot of slaughter and chaos simply by existing. Eventually, it turns out that [[spoiler: the prophecy in question actually tells about what will happen if the protagonist should fail, making them TheChosenOne instead]].
** It's a little more complicated than that. [[spoiler: The Bhaalspawn exist to bring back Bhaal (he sired them in response to a prophecy of his own death, which has since come true), and the current prophecy deals with the doom involved in any of the Spawn resurrecting or replacing their father. The protagonist is trying to avert this end... [[YouCantFightFate ''which is also discussed in the prophecy'']],]] making them both the possible agent of the apocalypse and the potential means to avert it.
*** [[spoiler: A moot point in DnDNext. It takes a hundred years, but Baal is FINALLY back, albeit weakened.]]
* In ''VideoGame/LunarTheSilverStar'', [[spoiler:Luna, a.k.a. The Goddess Althena]] nearly destroys the world after being brainwashed by the Magic Emperor.
** In ''VideoGame/LunarEternalBlue'', this same role falls to [[spoiler: Lucia, a counterpart of Althena in some intentionally vague way]], whose job it is to destroy Lunar to prevent [[GodOfEvil Zophar]]'s rise to power. She chooses not to. However, this allows Zophar to capture [[spoiler: her and take her power, becoming more dangerous than ever]].
* Furiae in ''VideoGame/{{Drakengard}}''. Her body is one of the few seals that prevent the end of the world- Thus it's her brother Caim's job to protect her. [[spoiler: So when she [[FailureIsTheOnlyOption inevitably]] dies... Hoo boy]].
** Pops up again in the game's sequel and prequel. ''VideoGame/{{Drakengard 2}}'' has Manah, [[TheAtoner repentant]] BigBad of the first game by way of DemonicPossession...which unfortunately was never fully dealt with, meaning the Watchers are able to subconsciously manipulate her into becoming their vessel again. ''VideoGame/{{Drakengard 3}}'' has [[spoiler: Zero and all of her Intoner 'sisters', though of the latter, only One knows about this. The flower growing in Zero's eye is part of an EldritchAbomination, which granted the Intoners reality-breaking magic that will eventually drive them insane and turn them into monsters.]] Unsurprisingly, given [[BittersweetEnding the general tone]] of these games, there's no real way to avoid it - [[spoiler: Zero killing them only channels their powers back into her body. After that, it falls to her dragon buddy Mikahil to kill her and the Flower for good.]]
* Kachi is treated as one of these by the villains in ''[[VideoGame/SinAndPunishment Sin & Punishment: Star Successor]]''.
* In ''[[VideoGame/FirstEncounterAssaultRecon FEAR]]'', Armacham's researchers, particularly Harlan Wade, came to the conclusion that Alma [[spoiler: Wade]] was perfectly capable of destroying the world with her PsychicPowers. This was one of the reasons why they [[SealedEvilInACan sealed her away in the Vault]] at the age of eight. However, this only delayed the inevitable, and the efforts of Project Origin to make supersoldiers by [[spoiler: raising them in Alma's womb]] [[UnstoppableRage only]] [[MamaBear made]] [[RoaringRampageOfRevenge things worse]].
* The Dark Elf of the ''VideoGame/MegaManZero'' series. Originally created to become the cure to TheVirus that caused the war in the ''VideoGame/MegaManX'' series, she was later corrupted into servitude under a monster, who uses her as a way of committing genocide on the planet.
* [[EmotionlessGirl Nu]]-[[YouAreNumberSix 13]] in ''VideoGame/BlazBlue'' acts as a literal ApocalypseMaiden, with Hakumen's [[KnightTemplar "the ends justify the means"]] attempts to hunt her down and kill her acting as the "bud nipping" part of the description. The other half of the equation is the protagonist-as-hapless-pawn in the header: [[spoiler: Ragna is unwittingly playing into [[ForTheEvulz Terumi's]] hands, with Jin hunting ''him'' down in an instinctive attempt to stop the worst. Tragically, [[GroundhogDayLoop 99% of the time, Terumi wins]].]]
** [[spoiler: ''Ragna himself'' is apparently destined to be the "Destroyer of the World" who wields a power that even Terumi couldn't control if it was unleashed.]]
* [[spoiler:Elizabeth]] in ''VideoGame/BioshockInfinite'' was to be made into this by [[spoiler:Comstock]] through brutal emotional and physical torture. [[spoiler:Comstock planned to make Elizabeth his heir so that she may reenact his version of the Final Judgment and rain fire upon the "Sodom below". However, the Elizabeth who does accomplish this brings Booker to her timeline to give him a chance to stop all of that from happening.]]
** Booker [=DeWitt=] is a lesser version of this, after being revealed to be the "[[TheAntichrist False Shepard]]", prophesied by Comstock to lead [[spoiler: Elizabeth]] astray and [[HarbingerOfImpendingDoom bring destruction]] to Columbia. [[spoiler: This is because Comstock is actually the alternate reality [[AlternateUniverseReedRichardsIsAwesome version of Booker]] himself]].
* In ''VideoGame/SandsOfDestruction'', Kyrie can't control his powers; when that [[HearingVoices pesky voice starts talking]], his body acts of its own accord and obliterates everything around him. It's later revealed this is because he was born specifically to bring about the end of the world, as [[TheMaker the Creator]] feels it's too broken to allow to continue. [[AntiAntichrist He's not happy about this, and desperately searches for a way to]] ScrewDestiny. [[spoiler:When he decides he's too much of a danger to continue living, he asks Naja to kill him. Unfortunately, ''that'' doesn't work, either, as the Destruct has backup methods of resurrection.]]
* There's hints throughout ''VideoGame/YuGiOhBAM'' that ''you'' are this. You have amnesia, every villain wants to capture and recruit you, and your BAM skills quickly become the stuff of legends.
* In ''VideoGame/DiabloIII'' [[spoiler:Leah]] is unknowingly the final piece in [[spoiler:Diablo]]'s [[XanatosGambit grand plan]] to become the Prime Evil. Possessing her body, [[spoiler:Diablo]] was successfully resurrected and nearly destroyed the [[spoiler:High Heavens]].
* In ''VideoGame/{{Exmortis}}'', the AmnesiacHero of the first game turns out to be the Hand of Repose, empowered by HumanSacrifice to link the SpiritWorld to the Earth and unleash [[SealedArmyInACan the Army of Exmortis]]. AfterTheEnd, the protagonist of the sequel game journeys into the Spirit World to kill him, which severs the link -- though it's a bit late for humanity by that point.

[[folder:Visual Novels]]
* ''[[VisualNovel/ShallWeDateDestinyNinja2 Destiny Ninja 2]]'''s main character is cursed so that her homeland will be destroyed unless she is killed by her love interest before her coming-of-age. [[spoiler:In the good endings, the curse is broken]].
* In ''VisualNovel/{{Hanakisou}}'', Kuroto, who is quite sweet and innocent, must be killed or the world will end. [[spoiler:In the true ending, the world is saved without his sacrifice]].
* [[spoiler:Sakura Matou]] in the Heaven's Feel path of ''VisualNovel/FateStayNight''.
** [[spoiler: Ilya]] too, for related yet mutually distinct reasons. The holocaust at the end of the previous ''Heaven's Feel'' demonstrates just how much. [[spoiler:It would've been worse if Kiritsugu hadn't destroyed Ilya's mother and his [[HappilyMarried much loved]] wife, Irisviel]].
* In one of the endings in ''VisualNovel/SayaNoUta'', [[spoiler:Saya blooms and gives Fuminori her final gift: the world. She does so in the expense of transforming everyone on Earth into an EldritchAbomination much like herself]].

* Gwynn from ''Webcomic/SluggyFreelance'' during the period(s) when she was possessed by the demon K'Z'K.
* In ''Webcomic/{{Homestuck}}'', Aradia [[spoiler: brings about the end of her world through the game]]. Her username for a messaging service is even apocalypseArisen.
** Her last name is also Megido, a name derived from the mountain connected to the end of the world (Armegeddon is a shortened form of Har Megidon), and her title is Maid of Time.
*** Her ancestor's name is The Handmaid, [[spoiler: and is The Dragon to world destroying {{Big Bad}} Lord English.]]
** Snowman, former Black Queen and the 8-Ball of the Pool Billiard themed Felt.
--> Everyone always ceases gunplay when Snowman's around.
--> If you kill her you destroy the universe.
* In ''Webcomic/KnightsOfBuenaVista'', it turns out Adriana's PlayerCharacter is capable of this, due to excessive MinMaxing. Fortunately it would only happen when certain conditions are met, and the GameMaster avoids this by [[NoodleImplements banning gummi worms]] from the campaign.

[[folder:Web Original]]
* In the ''Roleplay/GlobalGuardiansPBEMUniverse'', Esmeree is a sorceress and a member of the evil Circle of Black Thorns. She became a black magician after her mother (an oracle) produced a prophecy that said that Esmeree would become great in the knowledge of the Black Arts, and would in the fullness of time overthrow heaven and destroy the world. It hasn't happened, yet...
* [[TheProtagonist Conor]] in the Podcast Novel [[http://podiobooks.com/title/shadowmagic Shadowmagic]]. [[spoiler: The prophecy ends up being true, it just refers to someone else]].
* A lot of people in the ''Literature/WhateleyUniverse'' believe Carmilla is going to be this. Right now, the protagonists are treating her as their best friend, to the point that Bladedancer is trying to find out who is trying to kill Carmilla. This could turn out really badly somewhere down the line.
** Tennyo is in some ways a better candidate for this, [[spoiler: as it was the Star Stalker's original purpose]], though only Sara and Gothmog knows this.
*** To clarify: Carmilla is supposed to be destined to create an army of {{Eldritch Abomination}}s from her womb, who will take over the world. Tennyo, meanwhile, just has DBZ level powers (though these are just a tiny fraction of the power of the being she's tapping into, [[spoiler: which was meant to destroy the multiverse if the Elder Gods could not be stopped]]). In a nice example, Tennyo is PERFECTLY okay with her friends having about 26 plans to kill her if necessary. As she trusts them to only use it IF necessary.
* In ''Roleplay/TheGamersAlliance'', [[spoiler:Leon Alcibiates]] becomes this when he almost manages to regain his Andain powers during the First Battle of Remonton. He realizes at that moment that as long as he exists as a revenant, his existence will eventually make magic disappear and cause the end of the world.
* The ''Wiki/SCPFoundation'''s [[http://scp-wiki.wikidot.com/scp-231 SCP 231-7]] is a pregnant young woman recovered along with six others and a document entitled "Seven Brides, Seven Seals" from a "satanic sex cult." The first gave birth shortly afterward; the resulting abomination killed an undisclosed number (the [[CensorBox censor box]] is at least three digits) of people before being put down by Foundation personnel. Attempts to remove the fetus, or the death of the mother, had similar results in the next five but with the scale of the event and number of casualties increasing exponentially. SCP 231-7 giving birth is expected to cause a [[TheEndOfTheWorldAsWeKnowIt class XK End-of-the-World scenario]]. The containment procedures which have prevented this so far are... [[NothingIsScarier best left unmentioned]]. Other than to say that they're worse than you think they are, and have caused numerous suicides among staff despite regular psychological examinations, short tours of duty, and [[LaserGuidedAmnesia class A amnestics]] available on request. [[spoiler:An EasterEgg message on the page reveals that the Foundation -- or people manipulating it -- doesn't want to find a better solution. They ''want'' the unborn Apocalypse right where it already is.]]
* [[spoiler: [[Anime/PantyAndStockingWithGarterbelt Panty]] and [[VideoGame/YumeNikki Madotsuki]]]] in ''WebAnimation/TheFrolloShow'' are targeted by [[spoiler:[[BigBad Wilford Brimley]]]] for his evil plan to become a world-scale menace. [[WebVideo/HitlerRants Hitler]] sums this up the best:
-->'''Hitler:''' He told me his plan back at the base. [[SarcasticConfession I thought it was a mere old man talk]]... [[spoiler: "Feed from [[BreakTheCutie the sorrow]] of the girl... breed with one of the angels... and spawn thousands of legions born with perfection."]]

* [[spoiler:Raven]] in ''WesternAnimation/TeenTitans''. A prophecy made at her birth pretty much guarantees that she will [[spoiler:act as a portal to bring her demon father Trigon to Earth so he can take over the dimension, starting by bringing about the end of the world on Earth. Raven, believing there is no hope, complies, but saves her friends, who work on defeating Trigon after the world ends, shockingly enough with the help of Slade. In the end, Raven decides her father has no power over her after all, and proceeds to beat the tar out of him]].
** Of course, it was a SelfFulfillingProphecy. [[spoiler:Raven acted as the portal to bring Trigon to Earth ''because'' she was so completely convinced she had no choice in the matter]].
** [[spoiler: That, and that her friends would die in their attempt to fight off Trigon's minions...]]
** However, it might be a ProphecyTwist: the prophecy states [[spoiler: that Raven ''will'' be his portal, and that "He comes to claim, he comes to sire the end of all things mortal." It doesn't say anything about him ''succeeding'' at the second part.]]
* [[spoiler:Flame Princess]] from ''WesternAnimation/AdventureTime.'' [[spoiler:Her heat increases gradually in any kind of romantic situation, and even a little thing like a kiss could do damage to the earth's crust, unleash molten lava, and instigate a [[AfterTheEnd second]] apocalypse.]]
* ''WesternAnimation/GravityFalls'': [[spoiler:In "Dipper and Mabel Vs. The Future," during a moment of emotional instability, Mabel Pines makes a [[BeCarefulWhatYouWishFor sympathetic but incredibly destructive and selfish wish]] and ends up turning the world into HellOnEarth.]]
