* Yasha from ''AsurasWrath'' is a combination of this and Stoic Woobie, who is legimately the one of the only deities that turned on Asura that feels legitimate regret fro the way they treat humanity after betraying asura, by forcing them into a MartyrdomCulture.
* In ''VideoGame/BatmanArkhamAsylum'' and ''VideoGame/BatmanArkhamCity'', Poison Ivy can be classified as a Woobie, Destroyer of Worlds because she is an eco-terrorist essentially because society harms Nature, her "babies", and she wants humans to stop hurting the planet. In addition, in Arkham City she locks herself up and really just wants to be left alone when Catwoman comes in and she sees herself forced to kill her.
* Fou-Lu from ''VideoGame/BreathOfFireIV''. He's an [[GodEmperor immortal emperor]] who also happens to be a [[PhysicalGod dragon]]. He's been [[KingInTheMountain hibernating for the past six hundred years]], during which time some [[TheEmpire not-nice people]] usurped his throne and plotted to have him killed when he awakens. He manages to escape the assassination attempts, mostly through turning into a large [[BreathWeapon energy-breathing monster]] and schooling them all in the arts of pain and suffering, and then goes about trying to regain his throne. Along the way, he runs into (and is hidden by) a [[CountryMouse nice, friendly farm girl]] who wears a bell as jewelry, who promptly [[LoveAtFirstSight falls in love with him]]. He falls for her, too, though he's [[IUhYouToo too much the stoic and quiet type to admit it]]. The {{Big Bad}}s find out that she's been harboring the Dragon-Emperor, take her captive, and drag her off to one of the [[PoweredByAForsakenChild more horrible fates imaginable]]. See, they have a [[EvilWeapon superweapon]], called the [[FantasticNuke Carronade]], that uses [[LoveHurts people with]] ''[[LoveHurts very]]'' [[LoveHurts close bonds to their target]] as [[HumanResources ammunition]], converting their pure soul (after a good amount of ColdBloodedTorture) into a foul and unspeakable city-destroying curse. So, the Emperor's walking through a forest on his way to his rightful palace to retake it, when he senses the powerful world-rending curse heading his way, and defends himself against it as best as he can. The last thing he sees before the force of the curse renders him unconscious is the [[ItsAllMyFault farm girl's bell charm falling from the heavens to land in front of him]]. Cue [[LaughingMad insane cackling]] and his plans going from "regain throne" to "[[KillThemAll kill everybody]]".
** A decision that is ''firmly'' cemented when he finally meets up with [[TheEmperor Emperor Soniel]], who acts as if he is welcoming Fou-lu back--and then proceeds to run him through with a [[EvilWeapon soul-eating sword]] created by [[KarmaHoudini his head thaumaturgist Yuna]] from a previous botched summoning where only the head came through. This would normally kill even a lesser being; Fou-lu is merely pissed off enough to [[OffWithHisHead decapitate the back-stabber with the very same sword]]. As if he needed any further cementing of the idea that HumansAreBastards...
* Kyrie from ''VideoGame/SandsOfDestruction'' is a unique example of this trope in that he is more than capable of destroying the world [[spoiler:(it was what he was created by the world itself to do, after all)]], but he ''doesn't want to do this in the least!'' His power brings about many a TearJerker in the game.
* Fortune and Vamp from ''MetalGearSolid2'' (with a little more emphasis on the Woobie bit in the former case and the Destroyer bit in the latter). The former endured the deaths of everyone dear to her, and as such is a [[TheResenter Resenter]] and DeathSeeker who happens to cause a lot of carnage with her {{BFG}}. The latter was the victim of terrorism, having to resort to cannibalism in order to survive in the ruins and developing a [[WhoWantsToLiveForever troubling immortality]] in the process.
* Duminuss from ''VideoGame/SuperRobotWarsReversal'', an artificial being (not sure of what she actually is, as she is only seen as a trippy eye glyph with a feminine/shota voice... and several {{Humongous Mecha}}s) whose only wish is to know her purpose. Her creator shunned her, and then she killed it. [[spoiler:Actually, her creator, Dark Brain, didn't die. He just implanted that memory into her for the lulz and left her]]. She shifts dimensions and invades the EXCELLENCE team labs searching for a time machine, to ask her creator for her purpose. She constructs 3 children, who are loyal and fight for her. Then Duminuss is destroyed, and her children kill themselves to bring her back. Then the heroes kill her again. She explodes, crying over how she'll die without ever knowing what was her true purpose. Unfortunately, [[VideoGame/SuperRobotWarsOriginalGeneration Original Generation Gaiden]] threw this out of the window and made her an unrepentant JerkAss...
** It's hinted that this isn't the same Duminuss, and [[spoiler:Dark Brain]] created multiple ones to do his dirty work. If it wasn't messed up like R's was, it makes sense that it's not the same
* [[spoiler:Sirus, aka Dark Emperor Griffon]], from ''VideoGame/DarkCloud 2''. [[spoiler:Originally a member of the Moon Tribe (aka anthropomorphic bunny) who loved nothing more than the flowers in the palace gardens, he was accused of trespassing. Alexandra [[RescueRomance interceded for him]] and made him the Garden Keeper. But then invading armies searching for the [[CosmicKeystone Atlamillia]] utterly ''annihilated'' the kingdom, leaving it a blasted wasteland, and killed Alexandra]]. [[LoveMakesYouCrazy His grief was so great]] that he swore [[OmnicidalManiac vengeance on all of mankind]], and started systematically ''erasing it from existence'' via TimeTravel, acquiring the MacGuffin for himself so he could reduce the world to nothingness. Regardless, the player and the protagonists are made to feel sorry for him by means of flashback scenes scattered throughout [[TheVeryDefinitelyFinalDungeon Moonflower Palace.]]
* [[spoiler:Yomiel]] in ''VideoGame/GhostTrick''. [[spoiler:He was falsely accused of giving secrets to the enemy and scared into thinking that he had no hope of acquittal, so he stole a police officer's gun and broke out of the police station, taking a little girl hostage out of panic. A shard of the just-crashed Temsik meteorite penetrated his back, freezing his body at the moment of death and severing it from his soul. By the time he finally pulls himself together and returns home, his fiancée has killed herself because he's been officially reported as dead. Yomiel is forced to wander the world alone, unable to die but not truly alive, separated from the rest of humanity. The isolation nurtures a darkness in his heart, making him want revenge on those who put him in that position, but he still desires most to have some way to lead a human life. His only friend and companion over those ten long years was a cat... and while trying to manipulate Lynne into shooting his shell, Yomiel accidentally kills him.]] Even his victims feel sorry for him when they find out his story.
* ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.'s]]'' Alma is a dead straight example of this trope. [[spoiler:Having been driven insane by her own psychic powers as a child, experimented on and locked up since she was eight years old, medicated into a coma and locked away in a shield vault for most of her life, forcibly impregnated and then having both of her children taken away, then killed once the project was terminated, all by her ''own father'', and ''then'' repeatedly shot at by ''one of her own children'' while trying to embrace him]], it's no surprise that the second she gets loose, people ''die''. ''F.E.A.R. 2'' continues her rampage as she tries to get revenge on everyone who ruined her life, and kills anyone who happens to get in her way.
** Except for Becket, who she, um, [[spoiler:[[StalkerWithACrush "covets"]].]]
** In [[spoiler:The Point Man]]'s defense, being embraced by Alma tends to be ''a death sentence''.
* Practically every villain of the ''Franchise/FinalFantasy'' series from VII onward is either this or else PutThemAllOutOfMyMisery, and arguably the villains from many of the previous games and spin-off lines.
** ''VideoGame/FinalFantasyVII'': Sephiroth, thanks to the revelation that he is the product of a MadScientist's experiment, compounded by the effect of falling into the Lifestream and being exposed to the voices of all souls not currently alive, warping his mind even more. His crossing of the MoralEventHorizon keeps him from truly being a [[TheWoobie Woobie]], but then again, he is the premiere DracoInLeatherPants of the ''Franchise/FinalFantasy'' series.
*** He's built up much more into this in the prequel, ''CrisisCore'', where his two best friends turn out to be [[FlawedPrototype flawed prototypes]], abandon Shinra, and are hunted down like animals. One goes insane and the other commits SuicideByCop in fear of doing the same, and in a few months, Sephiroth loses the only people he could relate to and any pretense of trusting the organization that rules his life. So when Genesis and Hojo set him up for TheReveal [[IAmAMonster about himself]] and Jenova starts messing with his head, he cracks because he's got nothing worth holding on for. Also, CrisisCore shows that prior to the Nibelheim incident, Sephiroth was a [[PetTheDog fairly decent and caring person]].
*** A much more straight example of this trope is [[spoiler:Dyne.]]
** While [[VideoGame/FinalFantasyVIII Ultimecia]] may not be a [[EpilepticTrees future version of Rinoa]], her own backstory is just as tragic. Due to being [[BlessedWithSuck a Sorceress]], she was persecuted her entire life because of the terrible actions of evil sorceresses in the past. Not only that, but thanks to history, she knows she is destined to die at the hands of a bunch of teenage mercenaries and all her plans are based on a desperate desire to [[ScrewDestiny escape her fate]]. Sadly, her actions in the past to achieve this goal caused the start of the persecution of Sorceresses in her own time. The story itself screws her over because of the subtle method of storytelling in the game, her backstory has to be pieced together from hints and comments by characters and plot events, making her seem like a GiantSpaceFleaFromNowhere.
** Kuja in ''VideoGame/FinalFantasyIX'' and Seymour in ''VideoGame/FinalFantasyX'' are PutThemAllOutOfMyMisery types, and thus their examples fall under that page. Seymour was waaaay too far gone to TakeAThirdOption, however.
** Shuyin in the sequel fits, however. Given that he was subjected to ''a thousand years of '''non-stop''''' MindRape until the start of the game, it's [[TheWoobie kinda understandable]]...
** It's implied that this affects [[VideoGame/FinalFantasyVI Kefka Palazzo]] in ''VideoGame/DissidiaFinalFantasy'' during his surprisingly [[AlasPoorVillain touching]] final scene in which it is implied that the reason Kefka became an AxCrazy NietzscheWannabe was because he's so damn insane, he thinks there's nothing worth living for except destruction. Terra herself says that he was destroying to try and fill his "broken heart".
*** Speaking of [[VideoGame/DissidiaFinalFantasy Dissidia]], [[spoiler:Chaos becomes one of these at the end. After destroying Cosmos, he realizes that he has no equal anymore (and possibly ends up horrified to remember that Cosmos was actually his artificial mother), and that the cycle of conflict is coming to a close. So he decides to destroy everything first.]]
**** While you don't find out exactly why [[VideoGame/FinalFantasyI Garland]] betrayed Cornelia, his actions in Dissidia are said to be motivated by him pitying Chaos and Cid of the Lufaine. Also, One Man's Monologue depicts him lying paralyzed in the destroyed parallel world for several days and clearly shows that he felt bad about his time loop shenanigans in hindsight.
** [[FinalFantasyXIII2 Caius Ballad]]. He was tasked by Etro to forever guard over the [[FaintingSeer Seeress of Paddra]] (Yeul), and [[BlessedWithSuck 'blessed']] with Etro's own heart, making him [[WhoWantsToLiveForever immortal]]. Which means he's had literally ''millennia'' of the same cycle; Yeul dies young, is reborn, dies again... etc. By the time the game starts, his mind has become so warped by the pain of her thousands of deaths, that he believes Yeul's cruel existence must be put to an end, and that [[TimeCrash stopping time itself from existing]] (after all, how can a seeress have visions if there's ''nothing'' to see?) is the only way to truly save her.
* Zephiel from [[VideoGame/FireEmblemElibe Fire Emblem 6 and 7]] [[spoiler:was a talented youth who did his best to win approval from his father, the king of Bern. But the harder he strove, the more distant his talentless father grew, and the fact that he was born from [[ArrangedMarriage a loveless marriage]] didn't help either. The final straw came when the king poisoned his heir's drink, several years after a first assassination attempt failed. Zephiel's closest retainer, [[WorthyOpponent Murdoch]], came up with the idea of faking his death to get him out of there. However, the king opened the casket, causing Zephiel to finally snap and stab him. According to his half-sister, Guinevere, Zephiel never smiled again. Years later, he (now king of Bern) was stirring up quite a bit of trouble in neighbouring countries, trying to offer the land back to its rightful owners because HumansAreBastards. He had to be killed... with his crestfallen sister's help, no less]].
** Another example is the true BigBad of the [[VideoGame/FireEmblemTellius Tellius]] games, [[spoiler:Prime Minister Sephiran]]. He was once a great hero, [[spoiler:one of four champions of Ashera, Goddess of Order, in her war against Yune, Goddess of Chaos. He was a kind man, and a member of the most peaceful race on the continent, the heron laguz; indeed, once Yune was subdued, he defied Ashera's order to kill her and simply sealed her away. As Ashera thereafter proceeded to thereafter seal herself, he promised her that Tellius would see no war for the next thousand years, with the goddess adding ominously that if that promise were broken, she would destroy the world. Sephiran married a fellow hero and started a family, a family that would found the greatest country on the continent, which, given his [[TimeAbyss absurdly long lifespan]] as a heron, he would continue to serve in high positions all his life.]] Everything appeared to be going fantastic for him. Then, nineteen years before the main story [[spoiler:a SmugSnake subordinate of his assassinated the country's beloved empress and pinned the crime on the herons, all but four of whom were wiped out in the resulting genocidal war. Sephiran]] resolved that a world in which ''that'' could happen simply didn't deserve to live, and resolved that he would [[spoiler:create a war so devastating it would wake the goddess and bring doom to all life]].
* ''{{Crimsoness}}'' casts one of these as the PlayerCharacter.
* Durandal, an AI from the ''VideoGame/{{Marathon}}'' trilogy, was deliberately threatened by his creator in order to drive him to [[AIIsACrapshoot Rampancy]] (as part of an attempt to safely study the process), made to open and close doors for hundreds of years in order to stifle his creative development and slow his Rampancy, and was probably about to be experimented on more when he entered the "[[KillAllHumans anger]]" stage of rampancy, secretly contacted hostile aliens and drew them to Tau Ceti to enslave or kill every single human on the colony or in the ship. Though he becomes less of a {{woobie}} later, when he turns into a BadAss {{Chessmaster}}.
** Let's be fair to the bastard. He brought the Pfhor as a distraction so he could get loose. Once that was done, he started working on stopping them, freeing their slaves (admittedly, to work for him), and helping the Security Officer do that which he does so well. The extermination of those on Tau Ceti IV was not intentional.
* The King of Planet FM from ''VideoGame/MegaManStarForce''. [[spoiler:Everybody, including his family, wanted to kill him to overtake his throne. As a result, he stopped trusting people. He destroyed Planet AM and almost Earth, because he thought that the people there would want to kill him as well.]]
** Jack and Queentia from ''Star Force 3'' also fit this trope like a glove. [[spoiler:They were once the prince and princess of a small, but prosperous country, which was attacked by neighbor nations for their advanced EM technology. And it just went downhill from there...]]
** [[spoiler:You could probably also say this for Burai/Rogue, also in the 3rd game. After the first time you fight him on your way to fight Jack Corvus, he may have shared his backstory, saying something along the lines of "Go ahead and save him. Later on, he will betray you."]]
* Strega of ''{{Persona 3}}'' is a trio of this, all of them being artificially [[BlessedWithSuck implanted with the powers of Persona by the Kirijo Group and forced to take drugs that shorten their lifespan in order to control their powers]]. The leader, Takaya, later [[spoiler:embraces [[EldritchAbomination Nyx]] coming to destroy life, proclaiming that his fight against [=SEES=] is him fighting for his way of life.]]
* ''VideoGame/ShinMegamiTenseiIV'' introduces the White, who are quite literally the AnthropomorphicPersonification of Humanity's despair over being pawns in the OrderVersusChaos ForeverWar. They are quite tired of it all as they believe ''everything'' plays into God's hands; they only want everything to go back to eternal nonexistence. So they have this giant MagicalParticleAccelerator built and a group of heroes suitably traumatized in hopes one of them will just go off the deep end, and as a living creature, give the universe a final death by breaking their machine and unleashing a chain of black holes to end the Multiverse for good.
* Several characters from ''League of Legends'' fit this trope.
** [[BlackMage Veigar:]] A member of a [[OurGnomesAreWeirder notably short and cheerful race]], he was driven insane from isolation while imprisoned in [[WretchedHive Noxus]]. He then spent years learning dark magic, and vowed to end conflict by bringing all nations to their knees.
** [[ColdSniper Varus:]] The guardian of the [[ExactlyWhatItSaysOnTheTin pit of corruption]] whose village was burned and family was killed by invading Noxian forces. Overwhelmed by regret and fury he absorbed the power of the pit of corruption, failing the sole task he was given in the process, in an attempt to gain the power he needed to exact his revenge.
--> ''"Beware a man with nothing to lose"''
** While Noxus seems prone to create this sort of character, they aren't without their own woobie.[[CrutchCharacter Urgot]] was once a proud, fearsome soldier of Noxus who threw himself into the fray until the day his hands were too mangled to hold a weapon. He was awarded for his loyalty by having his hands replaced by blades and given the role of High Executioner. While following a group of soldiers on a mission, he was going to get the opportunity to kill Jarvan IV, the prince of rival nation Demacia but before he was given the chance he was chopped down by a Demacian soldier named Garen Crownguard. Robbed of the grandest moment of his life, Urgot's sheer anger and hatred was the only thing that made him survive being rebuilt as [[http://images.wikia.com/leagueoflegends/images/a/aa/Urgot_OriginalSkin.jpg the necromantic cyborg he is today.]]
--> ''"Existance is torment."''
* The ''ShadowHearts'' series has a few, but [[spoiler:Masaji Kato]] from Covenant takes the cake. Having the woman you love being executed for treason? Bad, really bad. Managing to clone her, doing your best to make her clone remember everything so that you can finally be happy together, only to have to kill her again, and this time permanently, just as she starts to love you too? OUCH. No wonder he snapped after this and tried to create a new world by destroying the current one... Even the protagonists feel sympathy for him as the final battle starts.
* ''SilentHill''
** Alessa Gillespie is another textbook example. She was [[spoiler:burned to the point of near death but kept alive in excruciating pain, force-fed experimental hallucinogenics, and forcibly impregnated with ''[[OurGodsAreGreater God]]''. This was all done by her mother.]]
** Claudia from ''SilentHill3'' falls under PutThemAllOutOfMyMisery, however, since they wanted to rid the world of pain and suffering in general.
** Walter Sullivan from ''SilentHill4'' may count. He's just a [[PsychopathicManChild little kid]] who wants his mom back. Plus he was raised by a cult of {{manipulative bastard}}s.
* The Ur-Quan of ''StarControl''. [[spoiler:After spending thousands of years psychically enslaved by evil toads who force them to exterminate whole species of their friends, and finally clearing their minds only long enough to revolt by putting themselves through unspeakable agony, anyone would be in a bad mood]]. The ''nice'' ones want to forcibly subjugate all sentient life in the galaxy. [[OmnicidalManiac The rest want to eliminate it altogether]].
* The main antagonist in ''VideoGame/SuperPaperMario'', Count Bleck, who wanted to use the Chaos Heart to undo and redo all reality because he was heartbroken by his one true love. [[spoiler:Except it actually turns out that the "redo" part is a lie. He's ''that'' messed up by the loss of his love.]]
* Depending on how charitable you feel, the darker Forsaken from ''VideoGame/WorldOfWarcraft'' fall into this trope: their penchant for obscenely lethal plagues, doomsday weapons, and tendency to respond to any threat violently are a direct result of having once been decent, devout humans and elves before having been infected by the Plague of Undeath, killed, resurrected into undeath, corrupted by the Lich King and forced to massacre friends and family, and finally breaking free of his control only to be rejected by their faith and persecuted and hunted down by any remaining friends, family, and acquaintances. No wonder so many of them snap ''with apocalyptic fury''.
** Sargeras, the creator of the [[LegionsOfHell Burning Legion]], was so traumatized by the evil of some of the demons he fought against as the pantheon's chosen warrior that he decided that any universe where such things were allowed to happen was flawed, its attempts at Order pointless, and should be remade.
** Despite the fact that he wants to destroy the world because he doesn't like how mortals are using magic, Malygos can count because, let's face it, [[TraumaCongaLine his life sucked before he ultimately snapped.]] He was betrayed by his best friend, Neltharion (aka Deathwing, who had been corrupted by the [[EldritchAbomination Old Gods]]), who then went on to wipe out almost all the other blue dragons, coming very, ''very'' close to making Malygos the LastOfHisKind. He later ''supposedly'' regained his sanity (after being exposed to some volatile magical energies from another planet).
*** Maly's prime consort Sindragosa could also qualify. One of the blue dragons murdered by Deathwing, she wasn't only enraged by his betrayal, but she assumed ALL Dragons (including her mate) had betrayed her when they wouldn't answer her cries for help returning to [[ElephantGraveyard Dragonblight]]. She died very emotionally damaged. Mix in some Scourge corruption when the Lich King resurrected her to be his, umm... [[TheDragon Dragon]] and she's angry enough to help extinguish all life on Azeroth.
* Nessiah of ''YggdraUnion'' [[spoiler:has spent the past thousand-odd years living in misery, unable to age or die, as a punishment for being a pacifist in Asgard's time of war. He has spent his life since then [[RageAgainstTheHeavens trying to get revenge]] or just free himself, and makes a nice mess of the mortal world he lives in, in doing so]].
* [[spoiler:King Valentine]] in ''VideoGame/OdinSphere'' throws a SuicidalCosmicTemperTantrum in the final book by [[spoiler:using the Cauldron to turn Leventhan into a really pissed-off Sheng Long, which ends up destroying him along with the rest of existence]]. Granted, he got broken pretty hard before and during the story, beginning with [[spoiler:being forced to kill his own daughter because she had an affair with the king of an enemy country]], then dying horribly, along with most of his kingdom, after being betrayed [[spoiler:by his own son]], enduring endless torture in the netherworld, and escaping it only to be spitefully denied the complete destruction he was so desperately seeking, [[spoiler:by the dude who started the whole thing by shagging his daughter, no less]].
* [[spoiler:Vayne]] in ''ManaKhemia'', after he [[IAmWho discovered the truth]] and [[GoMadFromTheRevelation failed to take it well]]. [[spoiler:Faced with the problem of honestly thinking that the best thing for the world would be if [[DrivenToSuicide he were to disappear]], while at the same time ''desperately'' not wanting to face the loneliness he lived with before coming to [[WizardingSchool Al Revis]], he decides to take the school and everybody in it with him.]]
* [[spoiler:Xion]] in ''VideoGame/KingdomHearts358DaysOver2'', since her whole existence is a TraumaCongaLine.
* In ''VideoGame/{{Xenogears}}'', we don't know for sure how many times [[spoiler:Fei and Elly reincarnated Themselves]], but for 10,000 years, the scenario has been mostly the same: [[spoiler:they find each other, fall in love, and when they seem to be about to have a little [[HappilyMarried marital bliss]], they die a horrible and painful death]]. If you had the painful experiment he was subject to in his childhood, [[spoiler:Fei end up with a multiple personality disorder, with TWO of his personalities wanting to destroy the world: one is able to exist independently and jump from body to body, and the other one is a PersonOfMassDestruction]]. And that's not all: [[spoiler:Krelian, a friend of Fei in a previous life, is another woobie ready to destroy the world if it allows him to be "reunited with God"]]. With that many {{Physical God}}s and {{Magnificent Bastard}}s on the same planet, you can guess that the ''Xenogears'' world is not [[WorldHalfEmpty the most pleasant place to be]].
* Elpizo from the ''VideoGame/MegaManZero'' series exhibits traits of this trope, being sentenced to death for discovering records about a past [[MassHypnosis catastrophe]] in the ruined library ''he was ordered to examine''. He escapes this fate, only to get lots of people killed while leading a failed assault on his former rulers; this drives him to obsession and megalomania, and he decides that he wants to [[KillAllHumans re-enact the aforementioned catastrophe]].
** In the sequel series ''VideoGame/MegamanZX'', [[spoiler: [[CoDragons Prometheus and Pandora]], [[{{Jerkass}} despite]] [[ObviouslyEvil appearances]]]], are very much this. They spent a long time fuming at the fact that they were [[spoiler: made to be slaves for [[BigBad Albert's]] Game of Destiny, the punishment for disobedience [[YourDaysAreNumbered being their lives]]. Prometheus's FamousLastwords, after he [[TheStarscream kills]] [[ActuallyADoombot Albert]] and before he and Pandora are [[UnwittingPawn royally owned by Model W]], were a long rant about how pointless Albert's goal was, and that he might as well destroy the whole world thanks to the pain of what he and his sister had to endure]]. [[NoOneCouldSurviveThat It's unclear what happened to them afterwards]].
* Sarah Kerrigan from ''StarCraft'' killed her mom (and a whole mess of other folks) by way of a psychic accident, watched a kitten die of cancer, was forced to choose between killing her mentally ill father or her sadistic headmaster ([[TakeAThirdOption she just broke his gun]]) and decapitate a rebel leader (and steal his head), was experimented on, and was betrayed by her father figure. Then she got [[BodyHorror infested]] by [[HordeOfAlienLocusts the Zerg]]. Is it any wonder that she's a little crazy?
** Ironically, the one who made her that way also qualifies. The Overmind was forcibly enslaved by the Dark Voice into trying to commit genocide against the Protoss with the full knowledge that he and his Zerg would be wiped out once they did their job. [[ThanatosGambit Kerrigan was meant to be the one hope they had of breaking the Dark Voice's hold]].
* The only reason ''SonicTheHedgehog'''s Emerl doesn't end up as one of these is because [[spoiler:Sonic {{shoot|TheDog}}s [[PlayerPunch the]] [[TearJerker dog]] before it can happen.]]
** Chaos Zero in ''VideoGame/SonicAdventure'' and Shadow in ''VideoGame/SonicAdventure2'' also count.
* Ratchet, of the ''[[VideoGame/RatchetAndClank Ratchet and Clank]]'' series - he's a walking [[ApocalypseHow class 1]] at the very least, though he manages to avoid wallowing in his existential angst and/or loneliness pretty well by [[ReluctantMadScientist keeping busy]].
** Alister Azimuth fits this even better, being effectively an older, more cynical, and more ruthless Ratchet. [[spoiler:To the point that he very nearly [[TimeCrash destroys time itself]] in a misguided attempt to correct his own mistakes.]]
* [[spoiler:Ballos]] from ''VideoGame/CaveStory'', who [[spoiler:destroyed the very kingdom whose people he loved and helped out after being subjected to ColdBloodedTorture by the king (and if the Wii version of his speech is of any indication, he may have brought the torture upon himself by recklessly allowing his power to grow), forcing Jenka to seal him within the floating island. In fact, when you reach him at the end of the BonusLevelOfHell, [[DeathSeeker he begs you to kill him]]... or [[IllKillYou he shall kill YOU!]]]]
* If there were any worthier candidate for the epitome of this trope, it would have to be ''VideoGame/BlazBlue'''s Ragna the Bloodedge. [[spoiler:Not only did he lose his home at the hands of Terumi, but he was also betrayed by his brother, Jin, who cut off his arm simply because [[DisproportionateRetribution Ragna didn't pay attention to him enough]]. In addition, his younger sister had been kidnapped, and he was left to die. ''Then'', Rachel saves him from death by turning him into a half-vampire, causing him immense trauma and making his hair [[LockedIntoStrangeness turn white]]. Then, later, we find out that his sister is the template for a series of robotic clones, two of which are playable characters in the game. One of them, Noel, is a grown-up Saya for the most part, while the other, Nu, is a {{Yandere}} who wants to fuse with Ragna to complete herself and form the Black Beast, which turned the world into a [[CrapsackWorld crapsack one]] already.]] He's already flat-out stated that he hates everything because of these events.
** Jin's desire to kill Ragna (and thus the cutting off of his arm) is due to being the World's Antibody and part of his function as the Power of Order. He is meant to be the opposite to Ragna, who is the Destroyer of the World (by being the Black Beast). However, Ragna could instead become the Protector of the Azure.
** [[spoiler:Noel Vermillion]] eventually becomes one. [[spoiler:She]] was [[spoiler:nothing more than a clone of Ragna and Jin's dead/missing little sister, Saya. Since she looks like Saya, whom Jin despises, he's cruel to her. Noel understandably doesn't know why. She's ridiculously sensitive about her small breasts, and gets upset whenever anyone mistakes her as a boy (which is stupid in and of itself, since she's still visibly got breasts, hooray sexism). Making matters worse is that her best friend, Tsubaki, has been ordered to kill her as of the end of Calamity Trigger. Oh, and then Terumi gets ahold of her, mind-rapes her, and turns her into an unholy implement of destruction. All the hate and rage she kept pent up has now been amplified and directed towards the world itself.]]
* [[spoiler:Labtech X]] is motivated to destroy GaiaOnline by [[spoiler:a bad case of the CloningBlues and [[WellDoneSonGuy lack of approval]] from his creator/parent/original, Johnny Gambino.]]
* [[spoiler:Dr. Lantis]] of ''Star Ocean: The Second Story''. He loses his daughter, his last surviving relative, and goes insane from grief and rage. Because of this, he wants everything gone.
* [[CreepyChild Flandre]] [[PersonOfMassDestruction Scarlet]] of ''VideoGame/{{Touhou}}''. She may be [[CuteAndPsycho completely bonkers]] with the power to [[EarthShatteringKaboom blow up the world,]] but she is still a [[BadassAdorable cute little girl]] who has [[MadwomanInTheAttic never seen the light of the sun]] and [[OurVampiresAreDifferent probably never will]]. Many fans [[CutenessProximity want to hug her]], even though they know it will inevitably end in a [[LudicrousGibs shower of blood and gore]].
** Also from ''Touhou'', Yuuka Kazami is this. She is also CuteAndPsycho, and she is one of the most powerful youkai in the series (second only to [[RealityWarper Yukari]]). However, her BackStory is what makes her into this. Before the events of Lotus Land Story take place, Yuuka was in a deep sleep... [[AndIMustScream and was harassed by a nightmare-inducing demon who refused to let her wake up. FOR SIXTY. YEARS. STRAIGHT.]] She did posess [[WaveMotionGun the Master Spark]], but that doesn't help in a nightmare. Especially not one that you are not in control of. [[ArsonMurderAndJaywalking Also, ZUN calls her]] "[[BilingualBonus youkai]] [[IncrediblyLamePun moe~]]".
* [[spoiler:Aribeth]] from ''VideoGame/NeverwinterNights''. [[spoiler:She starts as a heroic paladin and your main ally, beloved by all and considered a national hero. Then the people of the city you and her worked your asses off to save force the government to execute her innocent lover for being an ''unwilling'' pawn in [[TheMole Desther]]'s plans. And the government had no say in it, ''the townspeople formed a mob and forced Fenthick's execution.'' In the next chapter, Aribeth is so filled with despair that the BigBad is able to manipulate it into hatred and rage, turning her against the titular city (and the player). Aribeth is especially pitiful when you face her in the finale, as, with her lover dead and feeling of betrayed by Neverwinter, you can tell that she feels she has nothing left to lose.]]
** The King of Shadows himself, the BigBad of the Original Campaign. [[spoiler:He started out as the greatest hero of the ancient realm of Illefarn. Then he volunteered for a horrifically painful ritual that turned him into a construct of pure magic, the Guardian, to make an effective deterrent to [[TheEmpire Netheril]]. Then the Netherese wizard Karsus tried to usurp Mystryl's place as god of magic and all hell broke loose. The Weave was interrupted and the Guardian faced destruction. He chose to continue his vigil over Illefarn by drawing power from the [[BlackMagic Shadow Weave]]. That's when he became the King of Shadows. Illefarn tried to destroy him and only succeeded in binding him outside the Material Plane.]]
** In ''VideoGame/NeverwinterNights2: Mask of the Betrayer'':
*** [[spoiler:Akachi the Betrayer]], who, as [[ThePunishment punishment]] for defying the gods by [[spoiler:trying to rescue his beloved's soul from the [[AndIMustScream Wall of the Faithless]]]], is turned into [[spoiler:the Spirit-Eater curse, an EldritchAbomination driven only by hunger and the instinct to possess bodies and devour spirits, always eating but never satiated]].
*** The Founder, the definition of WoobieDestroyerOfWorlds. She inflicted the PlayerCharacter with a soul-eating curse and set into motion events that threaten the very fabric of the ForgottenRealms, all to save her lover from [[AndIMustScream the Wall of the Faithless]].
* Morinth of ''VideoGame/MassEffect2'' claims to be this, stating that she never wished to be born an Ardat-Yakshi (the Asari equivalent of a succubus). Possibly subverted if it was ultimately her choice to screw and kill the galaxy's population, in that order, as opposed to her being controlled by an addiction that she never asked for in the first place.
** [[DarkMagicalGirl J]][[AxCrazy a]][[SociopathicHero c]][[BrokenBird k]]. She's probably the most powerful human biotic in existence and certainly one of the most powerful biotics of any species in the galaxy. Her backstory includes [[spoiler:being stolen from her mother as an infant, brutally [[ColdBloodedTorture tortured]] and [[PlayingWithSyringes experimented]] on by ''[[EvenEvilHasStandards rogue]]'' [[NGOSuperpower Cerberus]] [[EvilutionaryBiologist scientists]], used, abused, [[HeroicSacrifice watched the only person she ever truly cared about die to protect her]], and who knows what else.]] [[CosmicPlaything Yeah. Her life sucks.]] Good thing Shepard [[VideogameCaringPotential can help her deal with it and provide some measure of comfort]].
** The ''Overlord'' DLC adds a new one. Simply naming who it is would be a spoiler, but anyone who's played it will know which character it is.
** The ending implies that [[spoiler: the Collector General]] is one. [[spoiler: He's probably been controlled by Harbinger and the Reapers his whole life and was forced to do terrible things, all to aid in the galactic extinction cycle that claimed his own race. When Harbinger releases him as the Collector Base is being destroyed he sadly lowers his head in what appears to be remorse and [[DrivenToSuicide doesn't even attempt to escape the explosion behind him]], even though he easily could.]]

* ''SuikodenII'': Luca Blight's behaviour is a lot more understandable when you've absorbed the fact that he became that way after observing his mother being murdered while his father stood by, cowering in fear.
** More specifically, his mother was raped but not murdered as he was forced to watch, by mercenaries hired by Muse, the city-state his country was at war with, all the while expecting his father to ride in and saved the day, only to learn later that his father spent the entire time sitting on his throne, dithering. As an added bonus, his sister, Jillia, was the product of that rape, whom he loves and yet serves as a constant reminder of that day.
* ''SuikodenIII'' had this with Luc. In the first 2 games, he's a moody jerk who doesn't seem to have much motivation in participating in wars as his ParentalSubstitute mre or less drops him off. 15 years later, he concocts a plan to [[spoiler:destroy his [[MacGuffin True Wind Rune]] in a major case of crossing the MoralEventHorizon]]. The reason? [[spoiler:Turns, out he was a [[ArtificialHuman defective clone]] of another rune bearer who wanted vessels to [[GottaCatchThemAll collect all 27 of them]]. Even worse is that his rune gives him visions of an apocalyptic wasteland. He thinks that if he destroys the rune, he'll effectively kill god and change fate.]] This has caused many fans to categorize him as a WellIntentionedExtremist.
* In the "worst" ending of ''VideoGame/{{BioShock 2}}'', [[spoiler:Eleanor Lamb]] turns into one of these. She [[spoiler:was almost laser-guided by her mother to become some kind of Utopia, although some fans thought that she would become an Eldritch Abomination or an otherwise unpleasant form of Life that would destroy Rapture and the Topside World. In the Bad Ending, Eleanor is influenced by Delta's murders, kills her mother in revenge, and, depending on how many of the [=NPCs=] and Little Sisters the player killed, will be allowed by Delta to absorb his mind and, we assume, his powers, or will do the same, only against Delta's will. Whether the case, she swears to punish the world, while watching a storm fall over the corpse-filled ocean.]]
-->"''There is no Name for what I am. But, with your help, they will never see me coming... (Fade to Black)''"
** Keep in mind that [[spoiler:Eleanor watches Delta through the Little Sisters, so if he chooses to murder them, she experiences her beloved father horribly murdering her while she begs for mercy. Over and over.]]
* In ''Videogame/BioshockInfinite'', [[spoiler:Elizabeth becomes this in a BadFuture where Booker fails to save her and Comstock successfully molds her into his heir. In the end, it wasn't the mental and physical conditioning that broke her. It was the complete loss of hope and the belief that Booker betrayed her that drove her into wishing to burn the world. However, her final act is to bring Booker into this world to pass on an important clue to her past self that would change things.]]
* The King of Sorrow from ''VideoGame/{{Klonoa}}'' fits this trope perfectly. [[spoiler:Long story short, he ends up being ignored by the entire world for representing an emotion that everyone hates. He goes mad and, as an act of vengeance, decides to unleash sorrow all across Lunatea, which, judging by the reactions, will cause quite a bit of destruction.]]
** [[spoiler:He outright says that he plans to destroy the world when you reach him in the Terminus of Tears and it's pretty clear that he's gone AxCrazy]].
* [[spoiler:Melissa Bergman/MB]] in ''MetroidOtherM.'' [[spoiler:Her]] only crime initially was occasionally disagreeing with the other scientists on the Bottle Ship, but for that, they decided that [[spoiler:she had to have her emotions removed from her. She]] saw this as betrayal by her beloved mother [[spoiler:figure]], and as a result, everyone got horribly mauled by monsters.
* The 501st legion from ''StarWarsBattlefront''. Even though they're the Emperor's elite troops, somehow, you can't help feeling sorry for the narrator (who's quite obviously a ShellShockedVeteran), even when you're gunning down Rebels on Yavin 4.
* ''Franchise/{{Castlevania}}''
** Soma Cruz from ''VideoGame/CastlevaniaDawnOfSorrow'' - kill Mina, and he is going to kill you in revenge and proceed to become this, requiring Julius Belmont, Yoko Belnades, and Alucard to stop him.
** Dracula can be considered as one too. ''VideoGame/CastlevaniaSymphonyOfTheNight'' reveals that he once fell in love with a human, and had a son with her, and he was happy. Then [[HumansAreBastards some idiots]] [[BurnTheWitch accused her of being a witch and burned her]]. Dracula [[RoaringRampageOfRevenge snapped]].
** This happened at least TWICE. One lead him to become Dracula in [[VideoGame/CastlevaniaLamentOfInnocence the first place]], he was a devout man until she got killed, and went hog wild with the help of Death and the stolen power of another Vampire. After a while of this, he mellowed out and met a woman who might have even redeemed him... who then got killed by a bunch of witch hunters, causing him to REALLY lose it (Aulcard came from the second pairing, and takes it on himself to help shut down Daddy when he awakens).
* The [[EvilSorcerer Masked Mage]], from ''VideoGame/SeikenDensetsu3''. [[spoiler:He was Belgar, the Oracle of Shadows. [[DarkIsNotEvil Contrary to what his title might imply]], Belgar was [[GoodShepherd a wise and righteous man]] who watched over [[SaintlyChurch the Holy City of Wendel]] in tandem with the Bishop of Light. The tragedy began when a sick girl showed up seeking his [[HealingHands healing prowess]]. Feeling helpless upon realising that it was an incurable disease, he turned to TheDarkArts in search of a way; however, the girl passed on before he could find one. Belgar continued his research and subsequently started dabbling in necromancy. The dark arts gradually began tainting his soul and the Priest of Light had to exile him from Wendel. By the time ''Seiken Densetsu 3'' begins, he had become the [[FallenAngel vengeful Masked Mage]], one of the potential {{big bad}}s. It's such a TearJerker when you play the prequel and see what a good man he actually was.]]
** Cecilia from ''VideoGame/HeroesOfMana'' is another example.
* Jin Kazama shows some signs of this in ''VideoGame/{{Tekken}} 6''.
* You know that [[ProfessorLaytonAndTheUnwoundFuture Future Luke?]] Turns out, [[spoiler:he's not Luke, but Clive. He lost his parents thanks to a time-travel incident gone wrong, which interestingly also killed [[{{Foil}} Professor Layton]]'s girlfriend, and the person responsible is now the ''Prime Minster''! Thanks to a nice old lady's fortune, he decides to build a HumongousMecha to level London and rebuild it. Interestingly, Latyon actually prevented him as a kid from going back into the burning building on the day of the incident and, while he doesn't know why, got the Professor involved knowing full well he'd ruin his plans.]] As if he wasn't a fangirl magnet already...
* Anders in ''VideoGame/DragonAgeII'' becomes this by the end of the game. After a time growing up in the Mages Circle--a life stuck in a tower, bound to do whatever [[PathOfInspiration the Chantry]] asked him to--he escaped from the [[KnightTemplar Templars]]... seven times. On the last time, he joined the [[VideoGame/DragonAgeOrigins Grey Wardens to escape more permanently.]] It's all downhill for him after that, unfortunately. The Grey Wardens consider him a wuss and mock him enough that he leaves, and then he lets a wayward Spirit of Justice--once a friend of his--into his body. All of this isn't too bad, but it starts getting nasty when [[spoiler:he goes to Kirkwall.]] The sheer dark magic of the place corrupts Justice into a Demon of Vengeance. By the time Dragon Age II begins, he's constantly fighting for control over the influence of Vengeance/Justice. After all of this, his brooding is pretty justified. (He gets added points for being the constantly-hunted leader of a Mages' Rights group.) In the final act, though, [[DemonicPossession he can't fight Justice off anymore,]] and essentially performs a [[JumpingOffTheSlipperySlope terrorist attack on the local branch of the Chantry.]] Talk about a TraumaCongaLine. Ultimately, his fate is left up to [[PlayerCharacter Hawke.]]
* [[spoiler:Oersted]] from ''LiveALive'', Knight Chapter. [[spoiler:His story begins when he wins a tournament to gain a princess' hand in marriage and, in doing so, earns the accolades of the people, only for her to be kidnapped by the Demon King the following night. What seems to be a standard Save The Princess plot is soon turned on its head as the hero, Hash, who last slew the Demon King, is killed when fighting against it with the rest of Oersted's party. Then, the Demon King seems to assault Oersted in the night, only for it to turn out to be the king, who had been made to look like it—a fact discovered only after Oersted kills him. Now treated as a demon by the townspeople, Oersted returns to the Demon King's castle to save the princess, the one person who might still believe in him, only to encounter his best friend, Straybow, who seemed to have died in battle with the Demon King along with Hash. Turns out, he had orchestrated everything to make Oersted an outcast out of jealousy of the latter's success. On top of that, after Oersted battles and kills his old friend, the princess appears, accuses Oersted for not trying to rescue her when he had been trying to do so all along, professes her love for Straybow, and kills herself. With no one in the world now who doesn't loathe him, Oersted snaps and declares that, if the people want to think of him as a demon, why, then that's exactly what he'll become... the Demon King Odio. He then proceeds to slaughter every last person in the kingdom and send several incarnations of himself across time to test the virtues of humanity, thus starting the game's events.]]
* ''EpicMickey'':
** The smaller Shadow Blot is revealed to be this. His motives are just like [[OswaldtheLuckyRabbit Oswald's]]: he wants to be famous and loved by the people in RealLife. If you use paint, after [[http://www.youtube.com/watch?v=iYbFNLV329E Mickey's climactic battle with it]], he gives {{Mickey|Mouse}} a big hug, leading [[DeadpanSnarker Gus]] to marvel: "''Huh''? He's actually kind of... ''sweet''."
** OswaldTheLuckyRabbit. Much of what he does (and well, mostly what he ''intends'' on doing) is the result of neglect, jealousy, and the loss of everything he cared about (especially Ortensia) and built in the Thinner Disaster.
* As of ''VideoGame/{{Portal 2}}'', [=GLaDOS=] becomes this. After all, she [[spoiler:was originally a human, Caroline, [[BrainUploading forcibly uploaded into a mechanical shell]]]], and, because she was (understandably) resistant to the orders of the people who did this, was also subjected to MindRape due to the cores they forced onto her, hearing voices all her life, and soon killed every living thing in the facility.
** [[spoiler:Wheatley]] becomes this. At first, he's your friend and guide, helping you escape Aperture, but when he connects to GLaDOS's body and becomes in control of the facility, he goes mad with power and [[FaceHeelTurn betrays you.]] But during the final battle with him, if you listen long enough, he begins ranting. He hysterically claims that you've been using him and that you plan on running off with GLaDOS once you could escape. He even accuses that you didn't catch him when he disconnected from his management rail [[note]]Which is unfortunately true...[[/note]], which he honestly believed would kill him! And worst of all... he's ''[[TearJerker crying...]]''
* The novels for ''VideoGame/KingdomHeartsBirthBySleep'' paint [[spoiler:Vanitas]] as such.
* The [[spoiler:[[AxCrazy real Overlord Zenon]]]] from ''VideoGame/Disgaea2CursedMemories'' definitely is this trope. [[spoiler:Overlord Zenon is the famous and well-known "God of All Overlords" for [[OneManArmy having slain about 1000 other Overlords, 99 on the day she fled to Veldime to reincarnate.]] She doesn't appear much, but when she does, she tries to kill everyone, because she's convinced that everyone is going to betray her. Understandable, since nearly all the demons in the Disgaea universe tend to be rather ambitious. "Everyone who has ever come close to me, has betrayed me..."]]
** In ''Disgaea 3'''s "Human World Ending", after each of his party members dies one by one, Mao finally loses it when [[spoiler: Super Hero Aurum kills Raspberyl.]]. Afterwhich, he effortless annihilates him and we are told he destroys the universe, and Mao is left all alone, floating in nothingness for all eternity.
* Jack Krauser is retroactively implied to be of this trope in ''VideoGame/ResidentEvil4'', as Darkside Chronicles explains that his reasons for turning to Wesker was because that was the only option left for him to do the thing he did well at, fighting, after his mission with Leon resulted in him being fired from SOCOM due to an arm injury that never recovered.
* Many of the ghosts from the ''VideoGame/FatalFrame'' series have really sad backstories, and the only real reason they're attacking people is because they've been driven violently insane by the Malice/Darkness/Curse/etc that came out of the story's resident HellGate.
* ''Franchise/{{{P{okemon}}:
** VideoGame/PokemonDiamondAndPearl: Cyrus, as revealed in ''Pokémon Platinum'', was motivated by a childhood full of emotional neglect (if not more) to [[EndOfTheWorldSpecial destroy the universe so it could be recreated]] without emotion entirely, to end the suffering it caused.
** Interestingly, you hear about this from his grandfather, who was well aware of the ParentalNeglect and regrets not helping him, implying that it's possible Cyrus could have turned out normal if his grandfather had stepped in.
** In ''VideoGame/PokemonMysteryDungeonGatesToInfinity'', the reason that [[spoiler:Munna and her gang]] are working to ensure that the world's foreseen destruction comes to pass is that all of them had suffered terribly at the hands of others (exactly how isn't elaborated on) and believe that a new world free of injustice and pain can be created after the end of the current one.
** In ''VideoGame/PokemonXAndY'', AZ had a uniquely-colored Floette that he loved with all his heart, then it lost its life fighting in a war with other Pokémon. He single-handedly built a machine to bring it BackFromTheDead, but even after doing so he couldn't bring himself to forgive humanity for costing his Floette its life in the first place, so he modified his machine into an instrument of destruction and ended the war by ending thousands of other lives. The Floette was apalled by his act and abandoned him, leaving him to grieve [[ReallySevenHundredYearsOld for the next 3,000 years]].
* Schala, from the [[VideoGame/ChronoTrigger Chrono]] [[VideoGame/ChronoCross games]]. In ''Trigger'', she was abused and neglected by her mother, Queen Zeal, who went mad after discovering the power of Lavos. Schala was later caught in the Ocean Palace as it collapsed and never seen again... [[spoiler:until ''Cross'', when it was revealed that, since she had such a miserable life, she wished for none of it to ever happen. This let Lavos take over her soul, and turn into the Time Devourer, which threatened to destroy everything that ever existed. She finally gets a happy ending at the end of ''Cross'', when Serge uses the Chrono Cross to free her from the Devourer and RetGone Lavos out of existence once and for all.]]
* The freaking MAN-AT-LEGS from ''VideoGame/{{Pikmin}}'', believe it or not! Yep, that creepy mechanical spider that ''blasts your Pikmin to oblivion with a gun''! How? According to its journal entry, the Man-at-Legs has no need for the gun since it has no natural enemies, leading to the rumor that ''the gun controls the creature''! Let's look at it from the Man-at-Legs' point of view... imagine if you had a gun attached to you that killed everything around you that moved, and you were targeted by a giant swarm of insects for reasons beyond your control.
* Pyrrha, the daughter of FallenHero Sophitia in ''[[VideoGame/SoulSeries Soul Calibur V]]'' starts out as an innocent, drifting Woobie with no home or family of her own; being kidnapped by [[MagnificentBastard Tira]] at a young age followed by the demise of her mother resulted in her spending the next seventeen years of her life searching aimlessly for somewhere to belong, regularly attacked and forced to kill or be killed due to Tira's manipulations to make her a suitable heir to [[ArtifactOfDoom Soul Edge]]. When she finally reunites with her long-lost brother Patroklos, however, things finally seem about to get better for her. [[spoiler:Then Patroklos finds out Pyrrha is [[TheCorruption Malfested]] when she taps into her SuperpoweredEvilSide to save him from the BigBad, Nightmare. The still gentle and mostly-innocent but now ''utterly terrifying'' Pyrrha turns to Patroklos in concern to make sure he's OK only for Patroklos to point his sword at her in the midst of a HeroicBSOD, finally running away from her in horror. Pyrrha, heartbroken, decides she can never trust anyone but Tira and willingly takes up Soul Edge to escape being alone. The resulting entity Pyrrha Omega, is extremely violent and deadly compared to the frightened and naive Pyrrha, but she screams as much in ''pain'' as in rage while she fights, and doesn't seem so much to be possessed by Soul Edge as she is madly lashing out at ''everything'', thinking the entire world is her enemy and desperately needing to do something, ''anything'' to escape her pain.]]
--> [[spoiler:'''Pyrrha''': [[SanitySlippage Stop hurting me... stop rejecting me... stop killing me!!!]]]]
** Siegfried Schtauffen in the original ''Soul Edge'' and ''Soul Calibur'', and partially in ''Soul Calibur II'' prior to his quest for redemption. A teenage bandit who accidentally beheaded his own father during a raid, Siegfried completely lost his mind and set off in search of his father's "true killer." On recovering the Soul Edge from the defeated Cervantes De Leon, the Evil Sword completely consumed the fragile mind of the boy, transforming him into Nightmare. Whilst most characters fall under the thrawl of the Soul Edge on possession of it, it is implied the sword influences them to do evil, corrupting them with its power. In Siegfried's case, his immature and unstable mind allowed the sword to transform him into an extension of the sword itself. Eventually as the sword is weakened by its defeat at the end of ''Soul Calibur, ''Siegfried's will begins to reassert itself until he is finally able to break free and begin his quest for redemption.
* ''VideoGame/{{Iji}}'' has Iosa the Invincible. A maniacal BloodKnight even by her species' high standards, her lust for carnage began when the Tasen [[ApocalypseHow Alpha Struck]] her home planet, killing ''every living thing'' on it [[{{Determinator}} except for her]]. Afterwards, she desired nothing more than the extermination every last Tasen in existence.
** Iji herself can become one of these, depending on the player's actions. Indeed, Iosa is portrayed as her EvilCounterpart because their histories (and possible subsequent actions) are almost identical.
* ''Franchise/TalesSeries'':
** [[spoiler:Mithos Yggdrasill]] of ''VideoGame/TalesOfSymphonia'' definitely qualifies. [[spoiler:All he wanted was to make a better world and try to get rid of the FantasticRacism that plagued it while he was at it. After his sister dies, he spends the next four thousand years trying to revive her as he uses humans as lab rats for his plan to commit genocide by turning everyone into the same inorganic beings.]]
** Arietta the Wild from ''VideoGame/TalesOfTheAbyss''. First, her family got killed during the Hod War, and she's left to be [[RaisedByWolves raised by the Ligers]]. Then she got handpicked as a Fon Master Guardian for Ion, but quickly lost her position to Anise, [[spoiler:not knowing that the Ion she loved is dead, and the current one is only a replica]]. Then, her mother got killed. [[spoiler:And later, just when it looked like she may pull a HeelFaceTurn, Anise lets Ion get killed, which revokes everything Arietta thought about changing sides.]] Then, she challenged Anise for a final duel and... [[spoiler:she's not even told about the truth about Ion, leaving her to die miserably and not realizing the reality.]]
** [[spoiler:Paraiba]] in ''VideoGame/TalesOfHearts'', though on a smaller scale. After she absorbs Kohak's [[SoulFragment sadness spirune]], she tries to flood a town.
** [[spoiler:Lambda]] in ''VideoGame/TalesOfGraces'', as well as [[spoiler:Richard, thanks to MoreThanMindControl.]]
* The BigBad of ''VideoGame/RadiantHistoria'' turns out to be [[spoiler:the previous Sacrifice, who was less than amused by the fact that his asshole of a brother got to be king (and do a terrible job of it) while he was expected to die to hold off the end of the world. His exploration of the various possible futures just led him to the conclusion that [[OmnicidalManiac the world sucked so much he might as well destroy it]], so he [[RefusalOfTheCall up and left]]. The fact that King Victor's reaction to this was to kill his brother's favorite nephew to get himself a new Sacrifice probably didn't help.]]
* In the ''VideoGame/{{Disciples}}'' series, GodOfEvil is [[DeconstructedTrope deconstructed]] since the "evil" gods only became evil because their "good" compatriots were jerks who treated them like garbage. This does not apply to their followers. Bethrezen's [[LegionsOfHell Legions of the Damned]] are by far the nastiest faction who gleefully corrupt and slaughter in Bethrezen's name and TheUndead Hordes are utterly ruthless while following Mortis' will.
* The Origami Killer, aka [[spoiler: Scott Shelby]] in ''HeavyRain'' is the way he is all because his own father was a complete bastard who regularly abused him and his brother both physically and verbally and ultimately convinced him he was worthless, and then to top it all off was forced to watch his own brother drown and said dad refused to help him. And his mom, the nice parent, apparently contracted Alzheimer's and all but lost her mind so she couldn't take care of him anymore. And now he drowns children and puts their fathers through sadistic tests all in the deluded hope that they can save them and that the kids can have fathers that are worthwhile and will always be there for them, something he never had.
* General Nathan Sheridan, the BigBad of VideoGame/{{Fracture}}. When you read his back story you find out he sacrificed his career in the Atlantic Alliance military, his reputation, his friends and family all for the sake of his daughters, who were diagnosed with a rare genetic disease which couldn't be cured by conventional means. Desperate, he moved to the Republic of Pacifica, where there is no ban on genetic research. There the best geneticists worked tirelessly in a race against time to save them, but their efforts were futile and his daughters died within weeks of each other. And just to twist the knife in a little deeper six weeks after their deaths a cure was found. His wife divorced him soon afterwards and the rest of his life collapsed around him. Determined to make sure what happened to his daughters never happened to anyone else, he starts building an army the likes of which the world has never seen before to remove the ban on genetic research by force.
* [[DarkMagicalGirl Yuriko Omega]] from ''VideoGame/CommandAndConquerRedAlert3''. Found to possess psychic powers from an early age, she was scorned by her schoolmates, and eventually taken away from her family by the Japanese government to be placed into a weapons development program, which put her through TrainingFromHell to develop her inherent psionic powers, [[BreakTheCutie at the cost of her sanity]]. When World War 3 broke out, she was forced to fight by the Japanese military, who viewed her as little more than a weapon. After the defeat of Japan, she was captured by the Allied Nations, only to break out, partly to get revenge on the head scientist of the project, and partly to meet her "sister" Izumi. This sets off her campaign in the ''Uprising'' expansion. [[spoiler:While she eventually manages to kill the scientist and get her revenge, it turns out Izumi was always planning to kill her, and Yuriko is forced to kill Izumi in self-defence. In the ending cutscene to her campaign, she is shown alone and depressed on a hillside, overlooking a city, pondering what to do]].
* All three factions from ''VideoGame/SinsOfASolarEmpire'' to an extent. [[SpaceNomads The Vasari]] literally [[PlanetEater destroy whole planets]] while running from an enemy that practically wiped out their race. [[CycleOfRevenge The TEC Rebels]] want to [[RoaringRampageOfRevenge wipe out the aliens and "deviants" who nearly wiped ''them'' out.]] [[ChurchMilitant The Advent]] were just a peaceful collectivist/religious/hive-minded society on a desert planet. And then along came the Trade Order, who [[BurnTheWitch banished them from their homes for a thousand years for "deviancy."]]
* The Hecatomb in ''VideoGame/{{Phantasmagoria 2}}'' is revealed to be [[spoiler:the original Curtis Craig, thrown into the alien world when he was young by PAW and forced to grow up in a hostile alien dimension. He wants to destroy alien Curtis and kill his friends out of revenge.]]
* All of the Camerata in {{Transistor}} turn out to be this to some degree. [[spoiler:Sybil Reisz was a BitchInSheepsClothing before the game, but after the Process run amok, she ends up [[YouWillBeAssimilated assimilated]] and driven completely insane. Grant Kendrall just wanted to stop everything in Cloudbank from changing so damn much, and his husband Asher was only supporting him. When he sees what he's wrought on the city, Grant opts to take the [[DrivenToSuicide coward's way out]]. Asher stays for a while longer to halfheartedly justify himself to Red before [[TogetherInDeath doing likewise]]. Royce Brackett is the least sympathetic out of all of them, though he does [[EnemyMine help you reign in the Process]] before turning on you out of necessity. Even then, he has a moment of genuine remorse [[VillainousBreakdown when his way home vanishes for good.]]]]
* Big Boss, of the MetalGear series, had a life that could best be described as a TraumaCongaLine of absolutely ''epic'' proportions. First off, in 1964, he is forced to kill the only woman he had ever loved, the woman who had served as his mentor and mother figure for more then ''fifteen years'', all because somebody in the U.S. government held a grudge and set her up. Ten years later, Big Boss comes up with the idea for an "Outer Heaven". A place where soldiers can live free from the manipulations of governments, and be given the honor and respect they deserve. Along the way, he decides that The Boss abandoned her soldiers virtues, and therefore him as well.[[spoiler: This Outer Heaven is promptly destroyed, and Big Boss watches hundreds of the men and women he loved as brothers and sisters die in front of him, and he is sent into a ten year long coma]] After returning to action, Big Boss strives to take revenge and build his Outer Heaven, gathering a formidable army, and also nuclear weapons, only to be foiled and [[spoiler: crippled]] by his very own ''son'' Solid Snake. [[spoiler: Big Boss is then held unconcious, a prisoner in his own mind for over ''ten years'']] And when he is finally able to return and come to peace with his son, he dies soon after. All things considered, its a wonder Big Boss didnt snap ''sooner'' then he did.
