History Yandere / VideoGames

*** In one timeline, Nu happens to activate while Ragna and Tsubaki are in her chamber... She immediately decides that Ragna is cheating on her with Tsubaki and flies into a hysterical rage. Never mind the fact that Tsubaki is currently clutching onto her own LoveInterest, Jin. Turns out that being a female, alive, and in the same room as Ragna are three qualities that together make up one of Nu's {{Berserk Button}}s.

** Male example in [[spoiler:Streibough from the [[WhamEpisode Middle Ages chapter]]. He thinks he's [[EntitledToHaveYou entitled to have Princess Alethea]] after being AlwaysSecondBest to Oersted, and decides to fake his own death and ruin Oersted's life (starting by tricking him into killing the king) upon figuring out where she is when they go to save her. It [[GoneHorriblyRight goes horribly right]] -- he gets Alethea's favor and she kills herself to join him after he dies... and at that point the mental toll of Streibough's yandere antics is [[DespairEventHorizon too much]] [[ThenLetMeBeEvil for Oersted]] [[GreaterScopeVillain to bear]].]]

--->[in his English love confession to a girl!Avatar]: "I'll love you with every ounce of my blood, till I die. Ooh... when do you think that'll be?"

* Eriko, from ''VideoGame/PrincessConnectReDive'' is aggressively in love with Yuuki and only Yuuki. In her first anime appearance, she smacks the men who swarm her and at with her giant battle axe, and when she gets her hands on Yuuki, she ties him to a chair and tries to force a cursed ring onto his finger so he will be hers forever, looking appropriately utterly bonkers the entire time. Karyl has to perform a non-fatal heroic sacrifice so the rest of the Gourmet Guild can get him out.

* The Boss from ''VideoGame/SaintsRowTheThird'' can be one to Pierce, if you choose the Eastern European Female voice set; on top of being the par-for-the-course [[AxeCrazy sociopath]] the game's protagonist is regardless of voice set, she frequently makes it clear she has a thing for him, ranging from wondering if she can get cameras installed in his room, considering sending him a sex machine from "a secret admirer," offering to be his dominatrix, and finally admitting to wanting to make love to him in front of a live studio audience. This being the same woman who drove a tank out of the back of a crashing plane, parachuted into a penthouse party and immediately proceeded to kill everyone in sight, and has a murder record on her that runs into the thousands, it would most likely not be a good idea to even kindly ask his...admirer to back off.

* ''Videogame/StarWarsTheOldRepublic'':

** [[spoiler:Mithos]] of ''VideoGame/TalesOfSymphonia'' probably counts - his love for his sister [[spoiler:Martel]] drove him to [[spoiler:attempt to eradicate the entirety of the human, elven, and half-elven races by turning them into sterile, immortal, and emotionless zombies because his sister was killed because of FantasticRacism. He ''snaps'' when Martel is briefly revived and tells him that this isn't what she wanted, and that her last wish is for him to stop it- he misinterprets it as she and he are TooGoodForThisSinfulEarth and both worlds should be flat-out destroyed]]. If anybody tries to tell him he's wrong, or says anything that could even be severely twisted around as being bad about his sister, he will kill you. ''Damn.''

* ''VideoGame/TwistedWonderland'': Platonic variant. [[spoiler:Malleus does not react well to the news that his foster father Lilia has decided to quit school and retire abroad, so he [[OneWingedAngel goes overblot]] and puts Lilia, the entire school and ''the entire island'' to sleep, putting them in happy dreams that he controls.]]

** From ''VideoGame/FireEmblemFates'', the Avatar's eldest sister on the Nohr side, Princess Camilla, is willing to kill anyone who tries to hurt or kill her siblings and ''specially'' the Avatar. Choosing the Hoshido path will cause her to [[DespairEventHorizon become so desperate and broken]] that she becomes murderous towards the Hoshidan family, since "if I kill them all, he/she will come back to me." Though compared to Tharja she's quite downplayed, as her support chains all but state that she [[BrokenBird became like this over time]] [[FreudianExcuse thanks to a horrific childhood]], as [[HeroicBastard an illegitimate daughter]] and part of Nohr's DecadentCourt. [[spoiler:And in the GoldenPath this is also downplayed since she's sent by Garon to kill the Avatar and his/her group, but once she's defeated and spared, she's easily recruited and becomes a valuable ally.]]

It [[GoneHorriblyRight goes horribly right]] -- he gets Alethea's favor and she kills herself to join him after he dies... and at that point the consequences of Streibough's yandere antics are [[FreakOut too much]] [[ThenLetMeBeEvil for Oersted]] [[BigBad to bear]].]]

-->'''Tharja''': I can't believe you made me love you! ...Course, if you back out, I'll murder you in your sleep.\\

* In ''VideoGame/{{Detention}}'', [[spoiler: Fang Ray Shin]] is a downplayed version. While she ''did'' [[MurderTheHypotenuse betray the hypotenuse to Taiwan's totalitarian government]], it's implied that she thought Ms. Yin would just be arrested, and the end result of her plan ([[spoiler: The forbidden book club, including Ray's friend Wei, arrested, Ms. Yin exiled, and Mr. Chang- [[AllForNothing the one Ray was in love with in the first place]]-executed, along with who knows how many others]]) horrified her and [[spoiler: [[DrivenToSuicide drove her to commit suicide]] out of guilt]]. To make matters worse, [[spoiler: Ms. Yin was never a romantic rival for Ray. The conversation Ray overheard which implied it was ''actually'' Ms. Yin warning Mr. Chang that it was dangerous for him to associate with Ray, since he was the supplier for her forbidden book club and Ray could get caught in the crossfire if they got caught.]]

** Subverted with [[spoiler: Queen Mikoto in the GoldenPath and the ''Heirs of Fate'' DLC stages]], as she shows up [[spoiler: wanting all of her children (or her potential grandchildren the Kanas, in the second case) killed so they can be TogetherInDeath]]... but ''only'' because [[spoiler: she both CameBackWrong and was BrainwashedAndCrazy by Anankos. The ''real'' Mikoto [[OoCIsSeriousBusiness would've never done that]], and once she's defeated, she returns to her normal self before dying again, apologizing to her children.]]

* ''VideoGame/KingdomHeartsChainOfMemories'': [[ArtificialHuman Riku Replica]] goes absolutely apeshit if he thinks you'll get between him and Namine. Also, [[TheStarscream Marluxia's]] plan was to brainwash [[TheHero Sora]] into one of these for Namine, hereby turning him into a pawn to take over the Organization. It almost works, and after Sora and Riku Replica learn they were brainwashed, this doesn't affect their feelings much. (Namine ended up having to wipe Sora's memories of her to get him to recover.)

* [[spoiler:Rachel, in the Sci-Fi Chapter]] of ''VideoGame/LiveALive''. She snaps after [[spoiler:Kirk, her boyfriend, dies]] and [[spoiler:she carries his body to her room and acts as if he is sleeping]]. It's easily one of the creepiest scenes in that chapter, let alone the game itself.

** Alfred, Aya's father, has this nature, especially in the real end. [[spoiler:He planned to turn his daughter into a doll when she reached the right age. However, in order to achieve this, he killed his wife who wanted to save her daughter from such a fate. Once Aya discovers the truth, she's rightfully terrified of him and spends the rest of the game running from her AxCrazy father]].

* ''VideoGame/{{Misao}}'' reveals that [[spoiler:Mr.Sohta/Kurata is one. He is a charming yet lonely man who seeks to be loved by any means. Should the object of his affections reject him, he will fly into a frenzy and kill her. In Misao's case, he chopped up her body after he killed her and declared her to be his. He also kept her severed hands in his desk drawer.]]

** [[spoiler:Mithos]] of ''VideoGame/TalesOfSymphonia'' probably counts- his love for his sister [[spoiler:Martel]] drove him to [[spoiler:attempt to eradicate the entirety of the human, elven, and half-elven races by turning them into sterile, immortal, and emotionless zombies because his sister was killed because of FantasticRacism.

* ''VideoGame/TwistedWonderland'': [[spoiler:Malleus does not react well to the news that his foster father Lilia has decided to quit school and retire abroad, so he [[OneWingedAngel goes overblot]] and puts Lilia, the entire school and ''the entire country'' to sleep, putting them in happy dreams that he controls.]]

* A.B.A from the ''[[VideoGame/GuiltyGear Guilty Gear]]'' series of fighting games, a humunculous who finds and declares her marriage to a demonic axe named Paracelsus. Her intense paranoia toward the possibility of others attempting to take him often leads her to manic violence. Throughout the majority of the her appearances it is left ambiguous as to whether or not Paracelcus reciprocates this love, though he expresses distress and occasional shame regarding his circumstances. In the arcade mode of ''Guilty Gear Strive'', the pair discover that Paracelcus' form is slowly breaking down into a black sludge because of A.B.A's intense emotional insecurities. She laments that their love is not genuine and apologises for forcing her feelings onto him. The latter objects to this, affirming that while they have both exploited each other in the past, he is content being with her and wishes to move forward meeting each other halfway, with full transparency, as her partner. To consolidate this, he magically changes his appearance to be clear blue, A.B.A's favourite colour.

** Derek C. Simmons, the BigBad of ''[[VideoGame/ResidentEvil6 RE6]]'', is obsessed with Ada Wong to a ludicrous extent. Not only does he turn his devoted colleague Carla Radames into a replica of Ada (after perfecting the process with other kidnapped women) but when Carla betrays Simmons, he goes even more nuts and can't tell the difference between the two women, attacking both of them and causing mass destruction across the world. It's escalates further when Simmons learns about Leon's [[DatingCatwoman relationship]] with Ada and spends the rest of the game trying his best [[MurderTheHypotenuse to murder Leon]] so nothing stands in the way of his "love".
** ''[[VideoGame/ResidentEvil7 RE7]]'' has multiple examples:

* Gil from ''VideoGame/HarvestMoonAnimalParade'' (Japanese version) seems like this when you get him to a certain heart level.
--> "I want to lock you up in my basement and keep you all to myself."

* Amy Rose from ''Franchise/SonicTheHedgehog'' was originally just a ClingyJealousGirl to Sonic, but began suffering {{Flanderization}} into this around the Adventure era, being willing to DropTheHammer if Sonic didn't reciprocate her advances. As of ''VideoGame/SonicLostWorld'', though, she is back to her original characterization.

Simmons the BigBad of ''[[VideoGame/ResidentEvil6 RE6]]'' is obsessed with Ada Wong to a ludicrous extent, not only does he turn his devoted colleague Carla Radames into a replica of Ada (after many trial and errors with other kidnapped women) but when Carla betrays Simmons, he goes even more nuts and can't tell the difference between the two women attacking both of them and causing mass destruction. It's escalates further when Simmons learns about Leon's [[DatingCatwoman relationship]] with Ada and spends the rest of the game trying his best [[MurderTheHypotenuse to murder Leon]] so nothing stands in the way of his "love".

*** Mia, Ethan's wife thanks to TheVirus she [[SuperpoweredEvilSide alternates]] [[SplitPersonality between]] loving him and sawing his hand off with a chainsaw. When Ethan shoots her in the head she says she loves him before collapsing. She gets better later, due to her HealingFactor.
*** Jack and Maguritte Baker (who are also infected) towards BigBad Eveline, they are completely devoted to her and see themselves as [[ParentalSubstitute her caretakers]]. So they both [[JealousParent become murderously jealous]] of Ethan and Mia, due to Eveline wanting them to be her father and mother while they’re demoted to honorary grandparents.
*** Eveline herself for the aforementioned Ethan and Mia. She torments both of them throughout the game and their rejection of her causes her VillainousBreakdown and she spends the finale screaming about all she wanted was a family while trying to kill Ethan.

* ''VideoGame/TwistedWonderland'': [[spoiler:Malleus does not react well to the news that his caretaker Lilia has decided to quit school and retire abroad as the latter's powers are weakening from [[ReallySevenHundredYearsOld age]], so he [[OneWingedAngel goes overblot]] and puts Lilia, the entire school and ''the entire country'' to sleep, putting them in a story of his own making so no one will leave him.]]

** Ereshkigal has a habit of taking the souls of people she likes to the Underworld and locking them in cages. It's only her current fusion with Rin Tohsaka that prevents her from acting on it.

*** Jack and Maguritte Baker (who are also infected) towards BigBad Eveline, they are completely devoted to her and see themselves as [[ParentalSubstitute her caretakers]]. So they both [[JealousParent become murderously jealous]] of Ethan and Mia, due to Eveline wanting them to be her father and mother while they demoted to honorary grandparents.

[[quoteright:350:[[VideoGame/BlazBlue https://static.tvtropes.org/pmwiki/pub/images/nuragnayandere_3.jpg]]]]

* ''VideoGame/{{BlazBlue}}'':

[[caption-width-right:350:"You're not allowed to have any other lovers, Ragna... I'm the only one who can have you..."[[note]]What makes this ''really'' creepy is, ''[[BrotherSisterIncest that's his sister]]''... [[CloningBlues Sorta]].[[/note]]]]

* ''[[VideoGame/Onmyoji2016 Onmyōji]]'' has [[AbhorrentAdmirer Kijo]] [[LiteralManeater Momiji]] who is so obsessed with Seimei she doesn't hesitate to hurl insults at [[AllLoveIsUnrequited Shuten-dōji]] and threaten to [[WouldHurtAChild devour Kagura]] for knowing Seimei personally, [[spoiler: even though the Seimei she developed a romance for in the past and the one she's fawning over in the present aren't even the same person.]] Adding to that Shuten-dōji himself whose animosity toward Seimei is because of Momiji, and Seimei has on hand a PsychoticLoveTriangle.

* Tira from ''VideoGame/SoulCalibur'', Nightmare's ''[[GenkiGirl very]]'' {{perky|FemaleMinion}} [[TheDragon Dragon]]. She is a PsychoSupporter [[UndyingLoyalty of his]] [[MadLove who explicitly wants]] [[CargoShip to become one with]] [[ArtifactOfDoom Soul]] [[TheCorruption Edge]], the EvilWeapon that the entire story revolves around. This gets [[LampshadeHanging a lampshade hung over it]] in the Gauntlet (a [[RuleOfFunny humorous]], [[CanonDiscontinuity non-canon]] story from ''Broken Destiny'', the PSP port of ''IV''), where she functions as Nightmare's unwanted StalkerWithACrush and wants him to [[DevourTheDragon eat her]] and destroy the world, saying that she'll kill anyone who gets in the way of her love.

* The ''VideoGame/StarCraft'' novel series The Dark Templar Saga suggests a similar relationship with the protoss being Yandere towards the xel'naga. After the xel'naga abandoned them, the tribes engaged in the biggest civil war the galaxy had ever known, killing each other because each held the others responsible for driving the xel'naga away. Many also hated the xel'naga for abandoning them... No surprise these became the ScaryDogmaticAliens of the setting.
** Sarah Kerrigan would also act similarly to Jim Raynor. While having no interest in being with him after being infested, she would taunt him with visions of them living together happily and would always refuse to kill him as she killed those around him. After she was deinfested, it's revealed that she still harbored feelings for Jim which caused her to torment him and brought him nothing but pain until she was rescued. No wonder he abandons her (temporarily) when she reinfests herself.
* [[spoiler:Dark!Jaesa]] in the Sith Warrior class story in ''Videogame/StarWarsTheOldRepublic'', if romanced, makes a hobby out of hunting down and murdering anyone the player character sleeps with.

* Amy Rose from ''VideoGame/SonicTheHedgehog'' was originally just a ClingyJealousGirl to Sonic, but began suffering {{Flanderization}} into this around the Adventure era, being willing to DropTheHammer if Sonic didn't reciprocate her advances. As of ''VideoGame/SonicLostWorld'', though, she is back to her original characterization.

* In ''VideoGame/FatalFrameII'' there's Sae Kurosawa, who's obsessed with her sister, and becoming one with her, to the point of IncestSubtext. She wanted to be one with Yae so bad [[spoiler: she ''deliberately fell'' to try to get her sister to stop and help her, getting them both captured by the villagers they were running away from. It didn't work]]. Her possessing Mayu seems to have rubbed off of Mayu, as she started showing more Yandere tendencies toward her own sister, Mio...[[spoiler: however, the "Frozen Butterfly" ending implies that Mayu was Yandere all along, and Sae just exacerbated it. Mayu decides if she couldn't become one with Mio by getting strangled, she'll become one with Mio by doing the strangling herself.]]

** Jin Kisaragi is another male example, verging on CuteAndPsycho. Any moment he's mentioned about his brother Ragna the Bloodedge, he drops all his cool exterior and goes HoYay to the max "Oh brother~" and expresses his "love" by trying to kill him. And when Jin and below mentioned Nu meet, and Nu loses, well...

** ''Franchise/CompilationOfFinalFantasyVII'' has some quite disturbing examples.
*** Sephiroth and the Remnants are this toward their "mother" Jenova. They are ready to kill in order to be reunited with her. Since Jenova is not human, and looks like a shattered corpse, that is very disturbing.
*** Sephiroth could be viewed as one toward Cloud, if you care for FoeRomanceSubtext. Further exacerbated by how, no matter what world he inhabits, even if it's not directly ''Final Fantasy'', Sephiroth can just never [[VideoGame/{{Ehrgeiz}} leave]] [[Franchise/KingdomHearts Cloud]] [[VideoGame/SuperSmashBrosUltimate alone]]. In ''VideoGame/FinalFantasyVIIRemake'', it's not even subtextual, with Sephiroth warmly describing the time Cloud killed him as "the crowning moment of [their] time together" and showing Cloud threatening visions of him killing Tifa and Barret, [[spoiler:even nearly physically killing Barret at one point,]] on top of asking Cloud [[WeCanRuleTogether to join him]] in destroying the planet. Much like Joker with Batman, Sephiroth wants his [[WorthyOpponent dear nemesis]] all to himself and sees Cloud's companions as obstacles to be removed. Additionally in Chapter 18, if you’re playing as Tifa (Cloud’s [[ChildhoodFriendRomance long standing]] LoveInterest), Sephiroth’s special dialogue to her during the battle consists of: “Begone” and “Leave” in a [[CrazyJealousGuy uniquely hostile]] tone.
*** Nero the sable may be one too, toward his brother Weiss, seeing how emotionally dependent he is toward him, and how worried he is for his safety. If it is in a brotherly or romantic way, that's all up to you.

* In ''VideoGame/Borderlands3'', Katagawa Jr. is described by Rhys and Zer0 as being obsessed with Rhys to a creepy degree, and is referred to as Rhys' "corporate stalker".

** After Katagawa accepts that Rhys is going to keep rejecting him, he [[spoiler:dresses up as Rhys' best friend Zer0 and tries to kill Rhys.]]
