* ''[[Sandbox/WhereWasMyHero Where Was My Hero...?]]'' shows a truly ''chilling'' types 1 and [[WhereIWasBornAndRazed 4]] example with none other than [[spoiler:[[VideoGame/SonicTheHedgehog Tails]], set in an alternate universe where he never meets Sonic]], his life gets worse and worse until he becomes an AxCrazy WoobieDestroyerOfWorlds with OmnicidalManiac tendencies.

* ''Series/{{Angel}}''. In "Promises Kept", we discover Slade Wilson's BackStory before he became [[Characters/BatmanDeathstroke Deathstroke]]. After getting off the island of Lian Yu, he decided to get out of active service for ASIS, working as a trainer instead. However seeing the news report that Oliver Queen was alive triggered his [[PsychoSerum Mirakuru-madness]]. When he snaps out of it, he realises he's slaughtered his fellow ASIS operatives with a katana.

* [[VillainProtagonist Sni]][[SerialKiller vy]] from ''[[https://www.youtube.com/watch?v=3WRr-KQjDxA La Sangre de Mi Sangre]]'' is another one of those rare characters who manage to fulfill ''every condition for it''. To elaborate, she was an EmptyShell CreepyChild who one day found a lost Garchomp, so she keeps him company, as time passes the Garchomp falls in love with her, she pretends to go along until she ends up BecomingTheMask. When her sister finds out and [[KnightTemplarBigBrother she]] [[PedoHunt kills him]]. Snivy, having watched this in secret, decides to go the BestServedCold route, preparing a trap for her sister and after she was done killing her, went back home and killed all her remaining family and friends for [[ForTheEvulz no real reason, even admitting as such]].

* ''Fanfic/BoldoresandBoomsticks'': Ruby's account of Grendel's origin tells that it was once a normal Beowolf Alpha before losing its paw to a huntsman. It then organized the slaughter of everyone at a party except said huntsman, chased him to a village, and left only one survivor in the village to tell the story.

* ''Literature/{{Heimskringla}}'': [[FounderOfTheKingdom Harald Fairhair]] gives his favorite son Eirik command of 5 longships (which would amount to at least 150 men) at the [[RaisedByOrcs tender age of 12 to go on a]] [[RapePillageAndBurn viking expedition]]. When he come home, he quickly gets the moniker ''[[NamesToRunAwayFromRealFast Bloodaxe]]''.

When he come home, he quickly gets the moniker ''[[NamesToRunFromRealFast Bloodaxe]]''.

* He's actually the protagonist (one hesitates to say "hero") rather than the villain a lot of the time, but SelfDemonstrating/{{Lobo}}'s origin story involves him killing off his entire ''race'' except for himself, because he was dissatisfied with the grade he received on a school project. PlayedForLaughs, since Lobo was originally a DeconstructiveParody of the NinetiesAntiHero.

* ''WesternAnimation/DannyPhantom'': [[WesternAnimation/TheUltimateEnemy Dark Danny]]. In an alternate timeline, Danny's friends and family were killed in an accident that Danny was partially responsible for. In his grief, Danny had his ArchEnemy Vlad Masters remove his ghost half... which then did the same to Vlad, merged with Vlad's ghost half, murdered the human Danny and went on a rampage for ten years.

* Helen Narbon in ''Webcomic/{{Narbonic}}''... insofar as she can be considered a villain. Apparently all mad scientists try to cause as much carnage as possible when they [[WithGreatPowerComesGreatInsanity go mad and get full control over their mad science abilities]]. Some of them were already evil before they were mad.

* ''Literature/{{Heimskringla}}'': [[FounderOfTheKingdom Harald Fairhair]] gives his favorite son Eirik command of 5 longships (which would amount to at least 150 men) at the [[RaisedByOrcs tender age of 12 to go on a]] [[viking expedition. When he come home, he quickly gets the moniker ''[[NamesToRunFromRealFast Bloodaxe]]''.

* While the extent of her evil is ''[[NobleDemon very]]'' debatable, [[TheArchMage Evangeline]] [[UndeadChild McDowell]] from ''Manga/MahouSenseiNegima'' is convinced that she underwent this. Extra credit though for three out of four points getting hit. She had just turned 10 when it happened. It is implied but not outright stated that she killed her family, and she had no reason to do so. Though it is heavily implied she was either not in control of herself when it happened or she wasn't conscious of it and only realized it happened after it happened.

* In ''FanFic/TheJadedEyesSeries'' Harry snaps and murders the Dursleys when he's six years old.

* [[VillainProtagonist Sni]][[SerialKiller vy]] from ''[[https://www.youtube.com/watch?v=3WRr-KQjDxA La Sangre de Mi Sangre]]'' is another one of those rare characters who manage to fulfill ''every condition for it''. To elaborate, she was an EmptyShell CreepyChild who one day found an lost Garchomp, so she keeps him company, as time passes the Garchomp falls in love with her, she pretends to go along until she ends up BecomingTheMask. When her sister finds out and [[KnightTemplarBigBrother she]] [[PedoHunt kills him]]. Snivy, having watched this in secret, decides to go the BestServedCold route, preparing a trap for her sister and after she was done killing her, went back home and killed all her remaining family and friends for [[ForTheEvulz no real reason, even admitting as such]].

* TabletopGame/ForgottenRealms: Sammaster's fall started in somehow similar way - he blasted slavers with spells, but in process also caused the deaths of the very people he tried to rescue. Not that he was the shining example of mental stability before this.

* ''TabletopGame/{{Warhammer 40000}}'' has Angron Primarch of the World Eaters. He was once a gladiator slave who along his fellow gladiators fought their way out to freedom against their Nucerian slavers. The Emperor sought him to join his crusade, but Angron refused, choosing to stay and die along side his brethren who are about to be cornered by the Nucerian armies. The Emperor then teleported Angron alone into his ship, leaving his fellow warriors to be slaughtered by the Nucerians. Angron never forgave the Emperor for what he did, when he became Primarch of the World Eaters his legion became the most brutal of them all, when Horus turned to Chaos he was one of the first Primarchs to join him, and soon became a Daemon Prince of Khorne. Indeed, when Angron was found by the slave traders who eventually sold him to the gladiatorial arena, he was naked, drenched in gore, and surrounded by the corpses of the Eldar assassination squad he'd butchered in self-defense when they attempted to murder him to pre-empt his falling to Chaos. Did we mention he was just a little boy at the time?

* ''VideoGame/FatalFrame'': [[spoiler:Kirie and the Himuro Family Head, Sae and Reika. All save Himuro resulted directly from a botched sacrifice, and Himuro got the curse second-hand. They all suddenly engaged in mass-slaughter, their victims becoming enraged, vengeful ghosts themselves who continued to claim victims decades or even centuries after.]]

** In the [[Film/TheForceAwakens sequel]], Kylo Ren's backstory involves him and the Knights of Ren killing all of [[spoiler:his fellow padawans in his uncle Luke's New Jedi Order. [[InTheBlood Like grandfather]], [[DiscussedTrope like grandson]]...]].

* ''WesternAnimation/KungFuPanda'': Depending on [[BloodlessCarnage how much]] damage you think he did (it's ambiguous), Tai Lung when he learned he would not be the Dragon Warrior.

** In the prequel trilogy, Anakin Skywalker's StartOfDarkness (murdering a camp of Sand People) and later his attack on the Jedi Temple. The slaughter of the Tusken Raiders was because they tortured and killed his mother.

* ''Lkiterature/{{Mistborn}}'' has a rare AntiHero example in Kelsier, who Snapped (i.e. became able to use his superpowers) after seeing his wife beaten to death by her overseers when they were slaves. "Many men had died that night."

* The Death Knight from ''VideoGame/FireEmblemThreeHouses'', or as he's more commonly know [[spoiler: Jeritza Von Hrym,]] though he real name is [[spoiler: Emile Von Bartels.]] [[spoiler: His childhood as Emile wasn’t exactly nice, with his father using Mercedes mother as a BabyFactory to create children that bear her Crest. When Mercedes and her mother escaped, an 11 year old Emile chose to stay to protect them from their father’s wrath. Years later, when his father found where they were hiding, Emile was driven to murder his father and the entire House Bartels in a blind rage when his father learnt out Mercedes’s mother was too old to have children, choosing to use Emile’s sister Mercedes instead, who was still a teenager.]] While he feels no regret for these actions, the event was so traumatising that he began to become a full on BloodKnight that would even kill [[spoiler: his big sister.]]

* Joe Darke in ''Franchise/AceAttorney'', a businessman who panicked after accidentally running over a man with his car and started to kill the witnesses of the accident (and the witnesses of ''those'' murders too).

* He's actually the protagonist (one hesitates to say "hero") rather than the villain a lot of the time, but ComicBook/{{Lobo}}'s origin story involves him killing off his entire ''race'' except for himself, because he was dissatisfied with the grade he received on a school project. PlayedForLaughs, since Lobo was originally a DeconstructiveParody of the NinetiesAntiHero.

* ''Manga/MyHeroAcademia'': While [[spoiler:Tomura Shigaraki]] UsedToBeASweetKid, this came to an abrupt end when [[spoiler:his [[MakeThemRot Quirk]] activates for the first time [[TraumaticSuperpowerAwakening following a beating]] from his [[AbusiveParents abusive father]]. He [[AccidentalMurder accidentally kills]] most of his family, before becoming a SelfMadeOrphan by deliberately murdering his father. [[GreaterScopeVillain All For One]] finds him soon after this, which triggers his StartOfDarkness in earnest]].

* ''Manga/MyHeroAcademia'': It's eventually revealed that while [[spoiler:Tomura Shigaraki]] UsedToBeASweetKid, this came to an abrupt end when [[spoiler:his [[MakeThemRot Quirk]] activates [[TraumaticSuperpowerAwakening following a beating]] from his [[AbusiveParents abusive father]] and he [[AccidentalMurder accidentally kills]] most of his family, before becoming a SelfMadeOrphan by deliberately murdering his father. [[GreaterScopeVillain All For One]] finds him soon after this, which triggers his StartOfDarkness in earnest]].

* ''[[Sandbox/WhereWasMyHero Where Was My Hero...?]]'' shows a truly ''chilling'' types 1 and [[WhereIWasBornAndRazed 4]] example with none other than [[spoiler:[[Franchise/SonicTheHedgehog Tails]], set in an alternate universe where he never meets Sonic]], his life gets worse and worse until he becomes an AxCrazy WoobieDestroyerOfWorlds with OmnicidalManiac tendencies.
