History WoobieDestroyerOfWorlds / AnimeAndManga

* Hiroki Sawada -- or [[BrainUploading Noah's Ark]] in the ''Manga/CaseClosed'' NonSerialMovie ''Anime/DetectiveConanFilm06ThePhantomOfBakerStreet''. A ChildProdigy who was [[IntelligenceEqualsIsolation already beyond what the Japanese elementary school can handle]], which sparked arguments among his parents, culminating in his mother [[TakingTheKids taking him to the US]]. When [[MissingMom she died]] soon after, he was adequately homeschooled and adopted by his father's employer, Joe Schneider, which quickly made him a LonelyRichKid, who also exploit his intelligence...Schneider's own fear of [[InTheBlood his ancestry's dark history]], though, [[DrivenToSuicide drove Hiroki to suicide]], [[BrainUploading leaving a digitalized form of himself]] behind, who caused a HolodeckMalfunction on Schneider's [[{{cyberspace}} VR game]] launch, taking 50 kids as hostages...

* Vincent from the ''Anime/CowboyBebop'' [[TheMovie movie]], having gone self-destructively homicidal from psychosis and the inability to separate his hallucinations from reality after becoming an unwilling participant in a SuperSoldier program that caused him to permanently hallucinate. His {{leitmotif}} "is it real?" just hammers it home.

* The Warriors aka the [[spoiler:Titan Shifter Trio of Annie, Bertolt and Reiner]] from ''Manga/AttackOnTitan'' fit the bill. Born in [[spoiler:The Kingdom of Marley]] they were [[TykeBomb trained at a young age]] to be Warriors and kill the humans living within the Walls [[spoiler:under the belief that they were "demons" who wanted to destroy the world]]. Only after destroying the Walls and letting in the Titans did they realise that the people they were send to kill were just that, people, which caused them emotional distress. Over the next five years they slowly integrated themselves to Wall life and, despite their best intentions, eventually came to care for several of the people that they were meant to kill. Once the deceptions are revealed they are shown to be wrecked with guilt [[ConflictingLoyalty torn between the bonds they created and the mission they need to complete]]. The stress of their deceptions eventually caused them to go insane and now all they desperately want is to complete their mission and go home.

* In ''Anime/PuellaMagiMadokaMagica'', [[spoiler:Kaname Madoka has been this for a few {{alternate|Timeline}} [[GroundhogDayLoop timelines]]. She's TheWoobie in all of them, because of nearly [[CrapsaccharineWorld every event in the course of the show]], but in any timeline where she survives Walpurgis Night as a MagicalGirl (i.e. all of them so far where she hasn't died during it), she's fated to become [[ApocalypseMaiden an extremely powerful witch]], and either has to be {{Mercy Kill}}ed by Homura or simply goes on to destroy the world whilst Homura goes back in time to try and fix things (again). In the final episode, she becomes this yet again but sacrifices herself in the process.]]

** To some extent, [[spoiler:Witches in general]] qualify. [[spoiler:A Witch is made when a magical girl lets TheCorruption take over her soul gem, transforming it into a grief seed. This usually happens when they cross the DespairEventHorizon. Now remember how many times characters are put into danger or outright killed because of Witches.]]

* Hao/Zeke Asakura in the ''Manga/ShamanKing'' manga. [[spoiler:Not so much in the anime, since he ramps his AxCrazy factor up during the finale, which, sadly, is a GeckoEnding.]]

* Crona of ''Manga/SoulEater'' has the 'destroy everything' part, by way of [[AmbiguousGender their]] reasoning that everything that they fears/threatens them should be destroyed (for much of the series, they understand no other way of 'dealing' with it). Given that [[AbusiveParents Medusa]] did and still does possibly intend to turn Crona into an EldritchAbomination in the style of madness incarnate [[BigBad Asura]], they could feasibly go all the way on this one. Until Our Heroes inevitably {{defeat|MeansFriendship}} them.
** In the manga, [[spoiler: Crona is the BigBad despite being a favorite character of the audience and cast.]] Crona ultimately takes all that potentially destructive power of [[spoiler: becoming a HumanoidAbomination like Asura, and consciously uses it to imprison Asura on the moon, even at the price of Crona's own freedom.]]

* [[spoiler:Kanto]] from ''Soil'' ''[[UncannyVillage New Town]]'' has had a rough life. [[spoiler:His dentist drugged and raped him as a child which caused him to feel so ashamed and, well, ''soiled'' that he cut himself; it got worse when the dentist reconnected with him in high school and, as proof of his twisted "pure" love, gave him the video of his assault. The shame intensified to the point where he couldn't stand to watch cats in heat and tried to burn down the resident homeless crazy cat lady's shelter (fortunately, he didn't succeed). Things seemed to get a little better when he met a nice girl, but just as he was about to have his first consensual sexual encounter, ''she disappeared from between his legs''.]] No wonder he wants to destroy the world by [[spoiler:enlisting the dentist's roughly ''three dozen unwitting current victims'' plus a victim by proxy (her rapists were also the dentist's victims) to cause enough anomalies to break reality]].

* In Anti-Magic Academy: The 35th Test Platoon Kiseki Kusanagi's powers drive her mad sending her on two omnicidal rampages.

* [[spoiler:Alma Jinnai]] from Anime/JewelpetTwinkle. Born as a twin from [[spoiler:Fealina]], one of Jewelland's greatest magic users who "[[DisneyDeath died]]" trying to reseal [[ArtifactOfDoom Battest]], she becomes the only one to possess magical power. In fact, her magical power is much higher than average, necessitating her to live separately in Jewelland away from her brother [[spoiler:Yuuma]], and turning her into lonesome girl always avoiding contact with others. Years of living in solitude with absolutely no friend other than her [[spoiler: self made]] Jewelpet, Diana, causes her to be rather shortsighted, her only aim being to revive [[spoiler:Fealina]] in any way necessary, even by utilizing dark magic and Battest, despite the fact that doing so will bring disaster to Jewelland.

* Anime/MobileSuitGundamSEEDDestiny:

** [[EvilCounterpart Gaara]], before his HeelFaceTurn. His father, [[AuthorityEqualsAsskicking the Kazekage]], made him [[SealedInsideAPersonShapedCan the jinchuuriki of the One-Tailed Beast Shukaku]] ''before Gaara was even born'', which resulted in his mother's death giving birth to him. During his childhood, everyone else in Suna was afraid of Gaara and no other children wanted to play with him because of his status as a jinchuuriki, and because of his tendency to lash out and hurt people unintentionally with his sand powers. After [[DespairEventHorizon his beloved uncle, the only person who ever seemingly cared about him, tried to kill him when he was six]], Gaara snapped and began allowing Shukaku to influence him, becoming an unpredictable, [[AxCrazy bloodthirsty]] OmnicidalManiac. He gets better after Naruto [[DefeatMeansFriendship knocks some sense into him]].

* ''LightNovel/HaruhiSuzumiya'': After going through nearly 15 and a half thousand of the same 2 weeks, Yuki gains emotions and becomes this. Except that she doesn't destroy the world. She steals Haruhi's powers and {{RetCon}}s reality for 1 year, according to the novels, and 3 years and 5 months, according to TheMovie. And she succeeds. And she's stopped by the protagonists.

Once the event is canceled, Nyarlahotep impersonates Azathoth's driver and takes him to the remains of the Soberania District, showing him what he's done to his once great city and family before killing him. Once this was discovered, Nyarlathotep is subjected to a farcical military trial by the Legitimacy Kingdom in order to avert a war that almost started between every faction.
