History WoobieDestroyerOfWorlds / FanWorks

* In ''Fanfic/ConstantTemptation'' Light is {{Ret Con}}ned into one again--he [[FreudianExcuse is given]] the BackStory that [[AdaptationalVillainy his father]] and [[BrokenPedestal role model growing up]] turned out to be a DirtyCop and [[PoliticallyIncorrectVillain raging homophobe]] who arranged the deaths of all Light's past {{Love Interest}}s. Light figured out that his father was behind the deaths and [[GuiltComplex blamed himself for it]] because he wasn't able to protect them. Light came to the conclusion that there was no [[ArcWords justice]] in this world but no one should suffer as he did, he wished there was ''some way'' he could protect everyone... [[StartOfDarkness and then Light found the Death Note]]...

* ''Fanfic/HarmonyTheory'': Charisma, a PsychoForHire and TheDragon to one of the stories two {{Big Bad}}s, is revealed to have been driven insane by her own special talent for ''killing'', which is constantly demanding that she kill everyone around her, and telling her the best ways to do so. Not only has this pretty much destroyed any chance she had at a healthy relationship, but it also [[spoiler: drove her into murdering her own brother and being disowned by her family, at ''ten years old''.]] Later, after Charisma has reached adulthood, she is so far gone she practically has an existential crisis when she ''doesn't'' want to kill her LoveInterest. [[spoiler: Chapter 33 reveals that she is so far gone, the only way she can see being at peace is to [[OmnicidalManiac kill ''everyone'']] and with a little help from the inverted Element of Loyalty, '''she can'''.]]

* Shockingly, the [[WoobieDestroyerOfWorlds WDOW]] in ''Cave Story vs. I.M. Meen'' is, in fact, literally none other than Website/DeviantArt itself, in the exact same fashion as [[spoiler: Ballos]]; as self-punishment for allowing extremely unhealthy and gratuitous amounts of Rule 34 to spread virally and plague the Internet like a disease, he has permanently locked himself inside the [[DoesThisRemindYouOfAnything Zeal Chamber]], deep down in the darkest depths of Internet fanfiction hell, with his inner pervertedness and fetishism growing by the minute to the point of becoming a Main/SuperpowerMeltdown when [[VideoGame/CaveStory Jack]] finally reaches his lair and attacks him.

[[AC: ''{{Crossover}}'']]

* In ''Fanfic/ConstantTemptation'' Light is {{Ret Con}}ned into one again--he [[FreudianExcuse is given]] the BackStory that [[RonTheDeathEater his father]] and [[BrokenPedestal role model growing up]] turned out to be a DirtyCop and [[PoliticallyIncorrectVillain raging homophobe]] who arranged the deaths of all Light's past {{Love Interest}}s. Light figured out that his father was behind the deaths and [[GuiltComplex blamed himself for it]] because he wasn't able to protect them. Light came to the conclusion that there was no [[ArcWords justice]] in this world but no one should suffer as he did, he wished there was ''some way'' he could protect everyone... [[StartOfDarkness and then Light found the Death Note]]...

* ''Fanfic/AbraxasHrodvitnon'': It's eventually revealed in [[Characters/AbraxasHrodvitnonTitansAndOtherCreatures Ghidorah]]'s {{backstory}} before it came to Earth that Ghidorah is this by origin. As described in Chapter 10 and further elaborated on by the author; Ichi, Ni and San were originally just three critters in an alien ecosystem fighting to survive, but they were captured by advanced alien AbusivePrecursors who [[TwoBeingsOneBody forcibly transformed the trio into the three-headed Ghidorah]] to be a BioweaponBeast, tortured them and hardwired TerribleTicking into their three brains which commanded them to "'''Kill Them All'''". Due to BeingTorturedMakesYouEvil, Ghidorah's middle head (Ichi, the "Eldest Brother") grew to hate any reminder of the now-dead Abusive Precursors with a white-hot passion, whilst the right head (Ni, the "Elder Brother") grew perpetually angry. Ghidorah TurnedAgainstTheirMasters and exterminated them almost as soon as they set it loose on its intended targets. When vengeance didn't satisfy the "'''Kill Them All'''" Ticking, Ghidorah tried inflicting destruction again and again to make the Terrible Ticking stop. After billions of years, the Ticking faded to a tolerable level, but by that time, Ghidorah had long since suffered SlowlySlippingIntoEvil which had made it the gleefully-{{sadist}}ic and psychopathic OmnicidalManiac it now is.

* Light is {{Ret Con}}ned into being one in the ''FanFic/TheArtOfDrowning''--he becomes Kira because he wants to avenge his long lost childhood friend [[spoiler: [[ForgottenFriendNewFoe Lawliet]]]].
* In ''FanFic/ConstantTemptation'' Light is {{Ret Con}}ned into one again--he [[FreudianExcuse is given]] the BackStory that [[RonTheDeathEater his father]] and [[BrokenPedestal role model growing up]] turned out to be a DirtyCop and [[PoliticallyIncorrectVillain raging homophobe]] who arranged the deaths of all Light's past {{Love Interest}}s. Light figured out that his father was behind the deaths and [[GuiltComplex blamed himself for it]] because he wasn't able to protect them. Light came to the conclusion that there was no [[ArcWords justice]] in this world but no one should suffer as he did, he wished there was ''some way'' he could protect everyone... [[StartOfDarkness and then Light found the Death Note]]...
* [[ReformedButRejected Light]]/[[ChronicVillainy Kira]] and [[RoaringRampageOfRevenge Mello]] in ''FanFic/ACureForLove''. L even [[WhatTheHellHero calls them on it]]:

* [[AlternateCharacterInterpretation Light as Kira is this]] in ''{{FanFic/Solitude}}'' -- acting as Kira [[InferioritySuperiorityComplex allowed him to take back control that was taken from him]] though [[spoiler: he gets better in the end.]]

* ''FanFic/FreedomDiesWithMe'' has War Lilac; the whole story is more or less how she got to that state. She gets continuously thrown head-first through the wringer and, upon snapping, embarks on a long four-year rampage that leaves Planet Avalice a wasteland. Somewhat deconstructed; by the end of the story, she has grown weary of the grief and has become a full-on DeathSeeker.

* [[ThatManIsDead Harry Potter / Tristan Winter]] in ''FanFic/TheJadedEyesSeries'' Since the only thing Muggles ever gave him was abuse and scars [[spoiler: he brings about a Class 3 ApocalypseHow against the Muggle world.]]

* In ''FanFic/MegaManDefenderOfTheHumanRace'', the female Robot Master in the beginning of episode 8 is activated by mistake, feels pain almost immediately upon waking, is unable to speak, overhears Wily talking about wiping her memory, and doesn't get a name before running off. She also has a mean shockwave that demolishes parts of Skull Fortress.

* ''FanFic/InnerDemons'': One could argue that following the awakening of her [[EnemyWithin Queen persona]] and her subsequent FaceHeelTurn, Twilight Sparkle qualifies, from her own perspective at least -- she's convinced that her beloved mentor deceived her (which actually is true), and that her friends and brother abandoned and betrayed her (which is actually sorta true), so she's lashing out in anger at the world around her. And even if she didn't qualify beforehand, she definitely does qualify after [[spoiler:[[TheDragon Trixie]] -- the only pony left she felt she could trust -- is accidentally killed by Apple Bloom]]; after that, [[AxCrazy what little sanity she had left]] goes [[VillainousBreakdown completely out the window]], her powers fully consume her and [[OneWingedAngel transform her into an Alicorn]], and she decides that [[spoiler:rather than being Equestria's [[EvilOverlord ruler]], she'll be its ''[[OmnicidalManiac destroyer]]''.]] Celestia actually lampshades the definition of this trope when telling Shining Armor that his sister can still be saved from herself:

* The ''FanFic/PonyPOVSeries'' has the second BigBad, Princess [[spoiler:Gaia/Nightmare Whisper]] who is actually [[spoiler:Fluttershy's SuperpoweredEvilSide brought on by her "daughter" Fluttercruel (whom she's SharingABody with) [[NiceJobBreakingItHero accidentally performing the]] BreakTheCutie her "father" (Discord) couldn't do in a well intentioned attempt to teach her about nature's cruel side. As a result, Fluttershy becomes Nightmare Whisper in the same way that Luna became Nightmare Moon and tries to take over the world in an attempt to make it a utopia. She's ultimately saved by the others, thankfully.]]
* ''FanFic/EquestriasFirstHuman'': [[BigBad Hellfire]] had once been a proud soldier in Celestia's army, until [[spoiler: a dragon burned his wife and child alive. Celestia dismissed his desire for vengeance. Hellfire faked his death and slaughtered the dragon. However, feeling dishonored by Celestia, he decided to murder her and use forbidden spells to take over Equestria, his actions quickly shredding all sympathy for him]].
* ''FanFic/HarmonyTheory'': Charisma, a PsychoForHire and TheDragon to one of the stories two {{Big Bad}}s, is revealed to have been driven insane by her own special talent for ''killing'', which is constantly demanding that she kill everyone around her, and telling her the best ways to do so. Not only has this pretty much destroyed any chance she had at a healthy relationship, but it also [[spoiler: drove her into murdering her own brother and being disowned by her family, at ''ten years old''.]] Later, after Charisma has reached adulthood, she is so far gone she practically has an existential crisis when she ''doesn't'' want to kill her LoveInterest. [[spoiler: Chapter 33 reveals that she is so far gone, the only way she can see being at peace is to [[OmnicidalManiac kill ''everyone'']] and with a little help from the inverted Element of Loyalty, '''she can'''.]]
* ''FanFic/HerInnerDemons'': Sci-Twilight had endured bullying and abuse throughout her time at Crystal Prep. But the moment she became this was when Cinch and the Shadowbolts began pressuring into unleashing the magic, or face the loss of Everton and more scorn from her classmates. The stress and fury of defeat and losing her dreams pushed Sci-Twilight over the edge [[spoiler: and turned her into Midnight Sparkle]].
* ''[[FanFic/HeiroftheNightmare Heir of The Nightmare]]'': Luna endured antipathy from ponies who feared her night. [[spoiler: She was pushed over the edge when the [[ReligionOfEvil Knights of Ra]], a group of Celestia-worshiping fanatics, kidnapped and tried to murder her daughter Twilight. Luna chose to become Nightmare Moon, and strike down Celestia, so that she would be so feared that nopony would dare touch Twilight]].

* In ''FanFic/{{Team 8}}'', The possibility of Naruto becoming one of these is discussed. Itachi is attempting to break Kurenai's mind with his Dojutsu by making her live and relive the killing of herself and her team by a mob. She breaks it by forcing the illusion to faithfully recreate Naruto's likely reaction if he were to see Hinata killed: releasing the Kyuubi of his own will and letting it destroy the village.
* [[spoiler:Kazama]] eventually becomes one in ''Fanfic/{{Echoes}}''.

* ''FanFic/RosarioVampireBrightestDarkness Act VI'' has one in Talon Ryashen, the "Fairy Tale killer." He was [[WasOnceAMan just an ordinary boy]] until Fairy Tale kidnapped him off the streets and used him as a SuperSoldier experiment, turning him into a HalfHumanHybrid by [[SuperhumanTransfusion injecting him with Alucard's blood]]. He escaped the facility when the experiments were completed, and was rejected by his family because of what he had become; as a result, he has embarked on a crusade to kill anyone and everyone who is or was part of Fairy Tale, including {{Unwitting Pawn}}s, receptionists, and those who turned on the organization, such as Dark, Akua, and Kahlua Shuzen. As he puts it, Fairy Tale took everything from him, and he has nothing left to live for but revenge on the organization.

* ''FanFic/ThroughHerEyes'': Ruby isn't one of these ''yet'', but with her powers she very could well become one, and everyone in her life is trying to prevent it: she's a young girl with an incredible power - the ability to summon Creatures of Grimm - that she has [[PowerIncontinence very little control over]], and is forced to hide for fear of the violence people would inflict on her if it ever went public. While everyone acknowledges that Ruby is a fundamentally good person, she could be a walking apocalypse if ever pushed too far, [[spoiler: something Roman and the White Fang witness first hand in the climax]]. Ozpin reflects that they're ''very'' fortunate she grew up in a relatively happy, loving, and financially stable household, rather than being forced to experience the kinds of cruelties some other children are exposed to and giving her a reason to be bitter.

* ''FanFic/TheEndOfEnds'' tries to pull Beast Boy off as that, after he falls for the power of [[TomeOfEldritchLore the Dark Prognosticus]] and tries to [[OmnicidalManiac destroy the universe]]. His motivation for doing so is because he can't take life anymore after Terra does not want to come back to the team, following the ending of the show. Subverted heavily by the fact that he comes more off like a whinny little child who thinks breaking up with a girl is worse than losing your parents (or to compare to the WholePlotReference, losing your love) and wants to see everyone suffer.

** ''FanFic/TouhouTonari'' has [[CuteGhostGirl Yuyuko Saigyouji]] not able to control her powers over death while she was alive, which caused her to [[DrivenToSuicide commit suicide]].
** ''FanFic/TouhouIbunshu'' has Remilia, Flandre, Mokou and [[spoiler:Yukari]] as varying flavours of "death to everyone" due to a ''long'' life (or unlife, in the case of the former two) of despair.
** Subverted in ''FanFic/ImperfectMetamorphosis'' with [[spoiler:Rin Satsuki]], who despite suffering so much pain and abuse from nearly ''everyone'' around her since childhood she ''still'' doesn't want to hurt anyone, and her first action in the story is simply to discover why she had to suffer. It's everyone ''else'' who thinks she's this trope.
