The word "yandere", a term that blossomed in {{moe}} fandom, refers to a character who is [[LoveMakesYouCrazy crazy about someone else.]] [[AxeCrazy Literally]]. Despite the anime-inspired name, this type of character [[OlderThanDirt is much, much older than that]], as one of the earliest examples is Medea of Greek Myth.

The character almost always appears [[BewareTheNiceOnes cute and harmless]] on the surface... but underneath they are [[StalkerWithACrush obsessive, controlling, and sometimes just plain insane]]. Woe to anyone who happens to be the object of their "affection". Even more pity should be saved for anyone who [[GreenEyedMonster gets in the way]], as the psycho-obsessive is amazingly unwilling to [[MurderTheHypotenuse put up with any rivals]]. Some have long histories of mental instability and in some cases have always been [[DevilInPlainSight a little "off"]], perhaps the [[BewareTheNiceOnes product]] of BreakTheCutie. Often eventually goes off the deep end and becomes an AxCrazy GirlWithPsychoWeapon.

Interestingly, these types of characters can still be perceived as {{Moe}} if they can build up enough tragic audience sympathy, despite the argument that many originally become popular by being ''subversions'' of wishy-washy female characters until the fandom [[MisaimedFandom ended up loving them in the typical way]]. Sometimes this can actually play out in story, if the LoveInterest ever starts to rethink his relationship with this girl, she might threaten to harm ''herself'' if he ever leaves her. This threat might be explicit, but often is more subtle.

Such characters are almost [[AlwaysFemale always female]], [[PsychoLesbian regardless of]] the other character, if only because of the [[PinkBishoujoGhetto moe fandom sample bias]]. Male characters who display similar tendencies usually end up being mere [[JerkAss Jerk Asses]] rather than true psychopaths, but the occasional male yandere (specially if he's got CuteShotaroBoy or {{Bishonen}} looks) isn't unheard of.

See also ClingyJealousGirl, LoveMakesYouEvil, LoveMakesYouCrazy, StalkerWithACrush, and [[{{ptitlev7j92pykrb48}} If I Can't Have You]]. Compare StepfordSmiler and PsychoSupporter. Contrast with {{Tsundere}}, a female character who often ''acts'' cranky, but harbors a hidden sentimental side, and the BitchInSheepsClothing, in which a character is consciously using the illusion of purity and niceness to cover up a sadistic true nature (Though a BISC ''can'' become a {{Yandere}} if we add mental unstability to the mix).

Occasionally they are just {{Yangire}}, a subspecies where the psychosis is [[HatePlague an outside influence]] not related to love, which may or may not be removed.

{{Yandere}} may have emerged as a {{deconstruction}} of YamatoNadeshiko archetype: a perfect, obedient woman, who has no priorities of her own, except the ones of her family and her husband. A yandere is all that, only driven to logical extreme and then examined [[{{Realism}} realistically]]: a sentient individual put in such position would invariably experience enormous strain. No wonder that sooner or later [[BreakTheCutie she would snap]] at a slightest provocation. Ironically, it is this realistic take that makes a yandere so endearing to the audiences, often even more so than the traditional YamatoNadeshiko.

It should be noted that while many below listed examples are drama and horror ones, this trope is not exclusively PlayedForDrama. It might just as well be PlayedForLaugh through ComedicSociopathy as it is for drama or horror.

Almost all the examples listed below are '''spoilers''', so read at your own risk.

Part of the ''dere'' family along with {{Tsundere}} (angry outside, sweet inside) and {{Kuudere}} (cold outside, sweet inside).

----
!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* Gasai Yuno (seen smiling above) of ''MiraiNikki'' is the archetype of this trope. She will do ''anything'' to make Yukiteru stay with her, and is very good at everything short of not freaking him out. This is why her body count is higher than the rest of the cast combined. And she's one of the ''main characters''.
** Yuno was also [[spoiler: actually ''winning'' Yukiteru's affections... [[JumpingOffTheSlipperySlope until she went]] [[MoralEventHorizon massively overboard]] and Yukiteru fled]]. Of course, given that Yukiteru is probably the [[OnlySaneMan only sane diary holder]] (until she persuades him to get in touch with his inner psychopath, anyway) and all the others are, in fact, far worse [[spoiler:(even the ones originally on their side - though the Escape Diary holder seems to have pulled off a HeelFaceTurn)]] ''and'' that Yuno's affection is quite genuine (if [[{{Understatement}} warped]]), it's not like she had particularly strong competition until the later volumes.
** Also, Akise Aru [[HoYay really really likes Yukiteru]]. He's shown to be immensely interested in him, and follows him around, sticking his nose into Yukiteru's business. Not to mention the new development, which looks like a sort of form of MurderTheHypotenuse, where he tries to get Yuno away from Yukiteru by digging up dirt on Yuno and exposing her secret to Yukiteru.
* Suzu becomes obsessed with Tetsunosuke in the manga version of ''PeacemakerKurogane'', after [[spoiler: [[RapeAndSwitch being raped at the hands of an older male]]]]. He has [[StalkerWithACrush Tetsunosuke's every action monitored]], and becomes jealous and scared when Ryoma decides to take Tetsunosuke away with him, [[MurderTheHypotenuse taking drastic action to kill Ryoma]] and frame it on Tetsunosuke so Tetsunosuke won't be able to get away from him.
** You just ''know'' somethings wrong when his response to another characters question of why he hates/obsesses over Tetsunosuke so much is "this isn't hate--this is love".
* ''{{Saikano}}'': While Chise technically isn't one, her characterization certainly plays with this trope.
* ''{{Gantz}}'': Well, it certainly seems Reika's recent plan to score Kurono for herself wanders right into Yandere territory. It's just not going to be a good idea and, much like any attempt at scoring happiness, this troper predicts Very Bad Things.
** Surprisingly both of the Kurono's seem to have it remarkably under control considering. It's still going to end in tears mind you but that's a given for everything in this story.
* Momo from ''ToLoveRu'' shows a slight psychopathic side a couple of times, as a result of her extreme infatuation with Rito, and jealousy towards her sister Lala for gaining Rito's affections.
** Run is also willing to go to rather...extreme lengths to get Lala out of the way so she can have Rito for herself. It would be kind of creepy if it didn't always backfire horribly.
* ''{{Goshuushou-sama Ninomiya-kun}}'': Reika, hiding as a Tsundere-ish Ojou. To be fair, it's her alternate personality which is the ruthless one, the "real" Reika is just a incredible pervert who CanNotSpitItOut and ends up in lesbian situations a lot.
* In the ''SchoolDays'' anime, it's Sekai [[spoiler: who kills Makoto]], but Kotonoha who [[spoiler: kills Sekai]] her rival for Makoto's love.
** This was reversed in the manga, where Kotonoha [[spoiler:is the Hypotenuse that ends up killed]], and in some new bad endings of the PS 2 game. In one of these, Sekai [[spoiler:openly tries to push Kotonoha in the way of a train right after Makoto chooses Kotonoha over her, but ends up hit instead.]] Another strongly hints that Sekai [[spoiler:stabbed Kotonoha and left her to bleed to death in the streets... and Makoto knows that (and may have helped)]].
* Mizore, at least at first, in ''RosarioPlusVampire'' though Kokoa seems to have taken the spot ('course, not for Tsukune but for dear Moka onee-sama~!)
** Mizore's definitely yandere at her introduction, but since being admitted into the UnwantedHarem, she's more {{kuudere}} who finds it fun to continue "stalking" Tsukune.
** It sends shivers down the spine to even ''[[NightmareFuel imagine]]'' '''what''' manner of royally fucked-up brainwashing it took to produce a sociopath like Kahula.
* Nodame from ''NodameCantabile'' is a relatively mild case; in the Paris Chapter, when Chiaki wanted to break up with her, she beat the crap out of him (on a bridge overlooking the Seine!) until he changed his mind. At least she didn't bring out any sharp implements...
** During the fight, Nodame also makes a valid point—every time she thinks they're getting closer, Chiaki pulls away from her. Chiaki knows she's right, and it's implied that it helps cause him to relent just as much as him wanting the pain to stop does.
* Akira Kogami from ''{{Lucky Star}}''. When Minoru Shiraishi, says something that pisses her off, she often turns violent and insane, and then changes back into a kinder, lovable cutie.
** This is also an example of Minoru Shiraishi, for, in episode 21, [[spoiler: finally literally destroys the set in Lucky Channel after Akira Kogami sending him into the woods for water, but he ends up getting mauled by a bear, and being replaced for at least two episodes by Daisuke Ono]].
* ''NagasareteAirantou'': The women are determined to have Ikuto, the only male, to themselves, to an often violent degree.
* ''AskDrRin'': Tokiwa at first. [[spoiler: He was possessed by a demon though. It is apparent later on that he still has a crush on her]].
* Misa Amane from ''DeathNote''. Light killed the assassin of her parents. Misa becomes [[PoisonousFriend completely devoted to him]].
** There's also Kiyomi Takada, who was once Light's girlfriend. She ''really'' hates Misa for her involvement in Light's life and has suggested to Light numerous times that he should kill her.
* ''{{Naruto}}'': This is one possible interpretation of Karin's character. That is, her being a {{Yandere}} over Sasuke. She has a fluctuating personality, at times appearing stern and tough and other times appearing carefree and highly flirtatious. She's basically [[ClingyJealousGirl a pre-Time Skip Sakura]] except she's [[StalkerWithACrush even more extreme]]. Plus, there's the fact that she was planning on drugging Suigetsu and Juugo, so that she could "ravage" Sasuke's unconscious body. She also secretly kept one of Sasuke's sweat-drenched shirts for herself.
** Her actions towards Sasuke can get a bit {{Squick}}y at times.... For example, there's that peculiar conversation she had with Suigetsu which had him telling her that he knew "what she did to Sasuke" - she flips out about it, slaps him, and later we see Juugo questioning why, exactly, [[{{Squick}} Karin is rubbing herself all over Sasuke's discarded clothes]].
* ''PeachGirl'': Sae, in a way, towards whoever may be the current object of her "affection", most obvious in regards to Toji. Though she could be acting two-faced solely because of the fact that she is severely jealous of Momo and wants to ruin her life.
** Later on, Sae gives up on Toji and falls in love with Ryo. After finding out that he could care less about her and only loves Misao she becomes extremely hateful and rude towards Misao, and, at one point, tried to push her into the path of a oncoming bus. However, Kairi restrained her at the last second so she wasn't able to.
** Then there's Kairi's trio of ClingyJealousGirl's who are always quick to let Momo know how much they hate her for winning Kairi's affections. They harass/bully her regularly, accuse her of being a whore, and of not caring for Toji or Kairi's feelings. They threaten her with physical force and at one point, hold her down, and tell her that she has to sign a contract swearing that she'll stay away from Kairi or they'll burn all her hair off, and try to beat her up later on. (all while holding a lighter to her hair.) In addition, they take the threat even further with "We'll burn your face so badly that no guy will ever look at you again," and "Don't worry, we'll push you into the pool before your whole body catches fire."
* Leonard Testarossa from ''FullMetalPanic'' falls in love with Kaname and pursues her despite knowing that she doesn't like him, believing that she'll eventually come around. Personality wise he is an all-around nice guy, calm and gentlemanely. And when he kidnapped Kaname after besting Sousuke, he personally assured him that despite his attraction to her, he won't force anything, and will see to that nothing would happen to her. Later on, however, he becomes so enraged with Kaname not giving in to him, and "betraying" him by finally declaring to Sousuke that she loves him, that he slaps her hard enough to make her fall to the ground, speaks to her very rudely, and generally tortures her (more mentally than physically) in order to weaken her mind so that she won't be able to resist him.
*''SailorMoon'': Queen Beryl, and Ann after her, fixated on Mamoru in different violent ways. As well as [[EvenTheGuysWantHim the male alien Fiore]] in one of the movies. Emerald is also insanely jealous of Usagi because Prince Diamond is infatuated with her and she likes him herself. Also, ''both'' Ali and Prince Diamond are male Yanderes towards Usagi, and Ann, in addition to liking Mamoru, is rather possessive of Ali as well.
** Ironically, Ali, Ann, and Fiore all seem to be of the same species. Perhaps its an entire race of alien Yanderes?
* Rin Kokonoe from ''KodomoNoJikan'' towards her ''23-year old'' teacher Daisuke Aoki. She can get rather forceful at times, and considering how she's in ''3rd grade'' it's quite {{Squick}}y indeed.
** Reiji, near the end of the anime, seems to be extremely protective over Rin, going so far as to attack Aoki and keep her away from school.
** And Kuro has [[SchoolgirlLesbians a crush on her classmate Rin]], which causes her to frequently release her jealous rage against her teacher Aoki, since he in turn is Rin's (unwilling) object of affection. And believe it: Kuro can be [[CreepyChild downright scary]].
* Mimi from ''LovelyComplex''. Sweet and kind to Otani, malicious and hateful to Risa whenever Otani is not around. This includes threats, insults, saying that she doesn't deserve Otani, violent scuffles, and attempting to stab Risa through the hand with a pen.
--> '''Mimi''': (to Risa) If you get any closer to A-chan, I'll make whatever is left of your life ''extremely'' painful.
* [[http://tvtropes.org/pmwiki/pub/images/cit_shuffle_-_kaede_is_full_of_happy_feelings_-_THE_POT_IS_EMPTY.jpg Kaede Fuyou]] from ''[[{{Shuffle}} SHUFFLE!]]'' starts out as a [[YamatoNadeshiko gentle]] [[UnluckyChildhoodFriend childhood friend]], but [[BewareTheNiceOnes breaks down completely]] when the main lead finally starts pursuing another girl ([[spoiler:their sempai and local GenkiGirl, Asa Shigure]]), revealing an equally disturbing past with him that finally drives her over the edge. Her crazy side is known as "Boxcutter Kaede," after her... WeaponOfChoice.
* Shiho Munakata and [[spoiler:Shizuru Fujino]] in ''{{Mai-HiME}}''. Shiho's crush stemmed from a mad obsession with wanting to be with her [[UnluckyChildhoodFriend childhood friend]] Yuuichi Tate, [[spoiler:while Shizuru's innocent one-sided crush on her best friend Natsuki Kuga and [[MeaningfulName unfortunate mythological symbolism]] led her to take some rather...[[PsychoLesbian questionable measures]] for the sake of their happiness]]. Both characters got retooled in ''{{Mai-Otome}}'', with Shiho [[RescuedFromTheScrappyHeap becoming far less clingy]] and [[spoiler:Shizuru]] becoming a calmer and respected [[ActionGirl woman of action]].
* Nina Wang from ''{{Mai-Otome}}'' is a mild example; she's infatuated with [[spoiler:Sergey]], and when the latter dies, she [[BewareTheNiceOnes snaps so thoroughly]] she literally tries to [[spoiler:''destroy the world'']]. "Mild", because most of her actions were due to vile [[ManipulativeBastard manipulations]] by [[spoiler: Nagi and Sergey himself, who exploited Nina's affections to manipulate her into many evil deeds]].
** Don't forget Tomoe, who is a PsychoLesbian over Shizuru in ''Mai-Otome''.
* [[spoiler:Akito]] and Kagura Sohma from ''FruitsBasket''. The first has a pathological fear of being left alone ue to ParentalAbandonment ''and'' an EvilMatriarch mother's horrendous psychological abuse [[spoiler: which translates into horrible manipulations and wild mood swings]], the other is an odd mixture of both Yandere ''and'' {{Tsundere}} traits (she's a genuinely nice and quite cute girl unless Kyou is nearby, then she punches him and then goes to cuddle him in span of a few minutes).
* The {{Gundam}} series ''loves'' applying the trope to their characters:
** Sarah Zabiarov and Reccoa Londe in ZetaGundam.
** Another male example is Olba Frost from [[AfterWarGundamX Gundam X]], thanks to his huge Big Brother Complex towards his partner in crime and only relative he has left after the war, his beloved older brother Shagia. Action Girl Ennil El goes through trappings of this after she tries to let Garrod know he doesn't have to be alone and he shoots at her. She grows out of it with time, though, and gets together with Garrod's Lancer Roybea.
** FallenPrincess Flay Allster from ''GundamSEED'' is of the tragic subset. Her Yandere traits didn't appear until she saw her father killed, and she does [[IGotBetter get better]] by the end of the show, although [[FanDumb a lot of people]] [[DieForOurShip don't want to]] [[TheScrappy give her credit for it]]...
** {{Gundam 00}} has, Billy Katagiri, who literally become a [[ItsPersonal Mad]] [[MadScientist Scientist]] after he finds out [[spoiler: that his beloved Sumeragi just [[XanatosSucker used him]]]]. [[spoiler: Louise Halevy]], who [[spoiler: joined A-LAWS to avenge her family]], and Andrei Smirnov, who [[spoiler: [[SelfMadeOrphan killed his father Sergei]] [[OedipusRex to avenge his mother]] ''and'' [[MurderTheHypotenuse attempted to kill Saji Crossroad]], [[FreudianExcuse claiming it's for Louise' sake]].]]
* ''KeroroGunsou'' has Momoka, who uses her family's money for convoluted schemes to get closer to Fuyuki. She's mirrored with her associated alien Tamama, who is absolutely obsessed with getting the attention and praise of Sargeant Keroro and insanely jealous of anyone else, especially Angol Moa, who does so. Incidentally, Tama is ''male'', but seems to get this role because he is the youngest and most cutesy of the group.
* Several characters in ''[[RanmaOneHalf Ranma 1/2]]'' are accused of this by fans. See YandereDiscussion
** The entire point of Ranma's existance is fighting off Yandere characters, who are in love with one of his forms or see him as a rival for another character's love (usually Akane)
** Ranma himself/herself when under the influence of the Fishing Rod of Love becomes a truly terrifying Yandere towards Ryoga. Yes, it is hilarious. --"Now you've hurt my feelings."
** You know the poor bugger's dealing with some people with rather skewed minds when MurderTheHypotenuse is theoretically a viable tactic for killing (one gender) Ranma to win (other gender) Ranma. It applies, at the very least, to Tatewaki and Kodachi. Both are happily Yandere who are willing to kill Ranma if he happens to be wearing the wrong gender at the wrong time while they'd happily marry the blighter if he's wearing the gender they like.
*** You forgot Shampoo. Because Ranma beat her once in each form, he received a kiss each time. The kiss to his male form meant that, having beaten her, the culture in which she was raised dictates that he is her one true love (or something like that) and she intends to marry him. But first she has to sort out the kiss she gave to his female form, which, according to the same insane cultural rules, means she has to kill him (well, her). It's not quite MurderTheHypotenuse, but same principle.
*** Not really. Shampoo does try and kill Ranma outright when he finally tells her about being a GenderBender... but that's because he claims to really be a '''girl'''. After she returns from China, and it's been made clear that Ranma is truly a guy who turns into a girl, she never (deliberately) tries to kill him again, and Ranma is treated solely as being the guy she has to marry. This heavily implies that the KissOfDeath would have been called off straight away if Ranma had just revealed the truth back at her village... but then the AccidentalMarriage probably would have been put into effect much sooner, and Ranma wouldn't have that terrible first impression against Shampoo, and so it would have been much harder for Ranma/Akane to be the OfficialCouple... SoYeah. Or, in blunter terms, if Shampoo should be considered a Yandere, it shouldn't be from her initial "pursue girl-Ranma for death/boy-Ranma for love" behavior, as she was initially genuinely ignorant of the two being the same person and the motivation for chasing Girl-Ranma was wounded pride/dishonor, not romantic issues. That's DisproportionateRetribution, not being a Yandere.
* Shuichi Shindou from ''{{Gravitation}}'' qualifies when [[spoiler:the stress of Yuki being outed puts him into the hospital, and Shuichi, in the polar opposite of IWantMyBelovedToBeHappy, talks at length about how he would rather Yuki die than leave him.]]
** [[WhiteHairedPrettyBoy White-haired]] Tohma Seguchi is obsessed with Yuki too, to the point where he pushes Taki Aizawa in the path of a car (which [[SchrodingersCat runs him down in the manga]]) when he threatens to uncover Yuki's past and tells Shuichi that if he doesn't break up with Yuki, he'll fire his band from NG Studios -- all without losing his smile. Oh, and he's married to Yuki's older sister Mika. Take from ''that'' what you will.
*** Tohma is much further down this road than Shuichi in the manga, where he not only displays it far more often, but at one point also attacks Yoshiki dressed up as her brother ''with an axe'' for giving Yuki trauma.
* Ibuki Yagami from ''MaisonIkkoku'' flirts on the edge of this. Obviously a StalkerWithACrush to her [[HotForTeacher substitute teacher]] Godai, she is extremely manipulative and aggressive in getting what she wants. She often makes use of her girlishly innocent appearance to deceive people. In keeping with MaisonIkkoku being more realistic than Takahashi's other works, I think Ibuki fits as a slightly saner Yandere.
* Lucy in ''ElfenLied'', [[spoiler: who tries suppress her instinctive desire to kill all humans so she can live happily with Kouta, until she finds out he lied about the sex of the cousin he was going to a festival with, at which point she stops trying to be nice.]] As revealed in the manga, her true name, [[spoiler: like ol' 'Box-Cutter' above, is Kaede.]]
** She also isn't above acts of jealousy, once using her vectors to shove Yuka down when she saw her holding hands with Kohta. Also, after killing many people, plus Kohta's father and sister in a fit of psychotic rage when she was younger, she starts to go after Yuka, voicing her intent to kill her but only stops once Kohta tackles her and she sees his tear-streaked face. She ''still'' wants to kill Yuka, and hates her but refrains from doing so because she knows that Kohta would absolutely despise her if she did so.
** Nana is similar, in that she has a default cute personality but shows frequent signs of completely flipping out. She is also extremely devoted to her "papa".
** Yuuka gets close early on, but she backs off. What? He can't remember a promise due to his sister and father getting violently murdered in front of him about twenty minutes after making said promise in some rather guilt-inducing circumstances? That bastard. Guess I have to kick his ass now.
* Ran of ''UruseiYatsura'' is the poster child for (and likely the inspiration for all other) Yanderes. On the outside, she's a cute redheaded girl who likes frilly clothing, baking, and flirting with Ataru. In reality, she's an embittered childhood rival of Lum who is out for some very violent revenge on the girl for once dating her crush.
* In ''BattleAthletes Daiundokai'', [[spoiler: the shy Anna Respighi is revealed to have a repressed psycho streak. She severely injured her twin sister during a match in order to be qualified for the Cosmo Beauty competition. Unfortunately for her, the next time she tries such a thing is when she faces Myranda Arkar Walder, a girl with a much stronger and much more obvious psycho streak. Myranda easily defeats Anna, then proceeds to beat her up until she is stopped.]]
* Hiroko "Hiro-chan" Kaizuka from ''{{Narutaru}}'', as a side effect of BreakTheCutie. In her madness, apart from violently killing everyone who ever abused her, she also tries to eliminate ''any and all'' perceived obstacles to the friendship between herself and main character Shiina Tamai... [[spoiler:even if that means trying to kill ''Shiina's father'']].
** And in ''{{Bokurano}}'', Chizuru "Chizu" Honda picks up where Hiro-chan left off. She decides the best way to stop her predecesor's reluctance to [[spoiler: pilot a ship that would kill him]] would be to [[spoiler: slice his throat open.]] Then when she begins to pilot, Chizu [[spoiler: goes on a killing spree before even ''attempting'' to fight the monster, with the intent of murdering her teacher ([[HotForStudent who got her pregnant]]) and the people who he set up to gang rape her. Despite the fact that she would kill more bystanders in the process than all of the previous pilots ''combined''.]]
* Rirumu in ''Mirumo de Pon!'' Usually a very sweet and polite little fairy who ends all her sentences in "desu wa," when she uses her magic or her "fiance" Mirumo upsets her, her aggressive nature comes out.
* ''RomeoXJuliet'' has the polite, naïve Hermione, [[RomanticRunnerUp Romeo's fiancée through family arrangement]]. She looks [[YamatoNadeshiko cute, sweet and harmless]] even with the PrincessCurls hairstyle, right? Watch episode 16 and you'll see what a BreakTheCutie process and some anger management issues can do to her... Fortunately, she gets better.
* Slightly, Hikaru Hiyama from ''KimagureOrangeRoad''. Her normal self is a mix of {{Kawaiiko}} and ClingyJealousGirl, but the latter part gets more played out in TheMovie. [[spoiler: She gets better, though.]]
* The {{Omake}} spoof of ''ShakuganNoShana'', called "Shakugan No Shana-tan," plays with the idea of [[YamatoNadeshiko Yoshida Kazumi]] secretly harboring these tendencies.
* Aqua Crimson, ''MartianSuccessorNadesico'''s one and only VillainOfTheWeek (that is, one not directly related to the Jovians, the UEAF, or Nergal), was one. She's a charming, wealthy, beautiful YamatoNadeshiko who uses these traits to ensnare the first guy she sees, paralyze him with her (excellent, yet [[LethalChef poisoned]]) cooking, and get them both blown up so she can [[EmoTeen end her boring existence]] and become a "[[LoveMartyr tragic heroine]]". It's a good thing Akito's ''regular'' UnwantedHarem is so heavily armed, or he might not have survived.
* Hibari Ginza, the BadassBiker DarkActionGirl who pursues her old friend Saiga, from ''SpeedGrapher''.
* In ''{{Basilisk}}'', we have the [[FemmeFatale gorgeous]] and [[BrokenBird emotionally broken]] Kagerou. Madly in love with her [[KissingCousins cousin]] and leader [[WarriorPoet Gennosuke Koga]], but unable to be with him due to [[BlessedWithSuck her]] DeathBySex [[BlessedWithSuck powers]]. Now, let's throw little cute [[ShrinkingViolet Oboro Iga]] as Gennosuke's fiancée through ArrangedMarriage, [[PerfectlyArrangedMarriage have him fall for her genuinely]], and you'll have [[DespairEventHorizon an angry, despaired and hurt as Hell]] FemmeFatale ready to try killing poor Oboro countless times so she can have Gennosuke for herself.
** ''Long'' before we find out about Kagerou's little "crush", we are introduced to the Iga clan kunoichi Hotarubi, whose whole world revolves around her lover and fellow ninja Yashamaru. She gives out [[DeathGlare Death Glares]] to anyone who would even insinuate that he might be fooling around with over women. When Yashamaru goes missing at the series' start, Hotarubi tries to ask a near-death ninja who had fought him where he might be. When the poor bastard replies by spitting on her cheek, she stabs him ''repeatedly'' in the throat - even long after it's clear that he's DeaderThanDead - while screaming like a lunatic.
* ''CodeGeass'' loves to apply this trope to both genders.
** At first, Nina Einstein, the [[ShrinkingViolet shy and quiet]] [[{{Meganekko}} glasses wearing nerd]] from Lelouch's school, is only noticable for her exaggerated paranoia regarding Japanese people, perhaps because of a [[AllThereInTheManual traumatic incident]] where she was left behind in a ghetto. After RebelliousPrincess Euphemia blows her civilian cover to stop some Japanese terrorists from teaching Nina a "lesson" (aka, raping and killing her), she becomes [[PsychoLesbian fixated on her]], masturbating to a picture of her and [[spoiler:attempting to blow up herself and the school after the Euphinator Incident]]. She gets better. [[ForScience Not smarter]], but at least more sane... after going ''[[JumpingOffTheSlipperySlope even madder]]'' for more than a while, that is.
** The telepathic [[PsychopathicManchild Mao]] went insane from [[PowerIncontinence being unable to control]] [[BlessedWithSuck his powers,]] and unceasingly listens to recordings of C.C.'s voice to comfort him. He wants to fly to Australia with C.C. and live happily ever after together, but she's just too big to fit in the plane's cargo hold. That's why, in his own words, [[ChainsawGood he'll have to make her compact!!!]] =D
** Rolo Lamperouge, Lelouch's "[[TykeBomb brother]]" from the second season, is a shy, CuteShotaroBoy on the outside but in truth [[spoiler: a trained assassin, raised by the Geass Cult as a TykeBomb to kill others using his Geass]]. [[WhenAllYouHaveIsAHammer This tends to be his solution to a lot of things, actually]]. He becomes ''[[BodyguardCrush extremely ]]''[[BodyguardCrush devoted to his "older brother"]]; he [[spoiler:kills Shirley Fenette because she [[HeKnowsTooMuch knows that Nunnally is Lelouch's real sibling]] and wants to help them be together and plans on killing Nunnally]] so that they won't get in the way of his and Lelouch's brotherly love. Lelouch ''really'' [[WhatAnIdiot wasn't thinking]] when he [[spoiler:sent '''Rolo''' to rescue his sister]]... Still, in Rolo's defense, [[spoiler: he ''does'' save Lelouch after he's ditched by the Black Knights... [[RedemptionEqualsDeath at the cost of his own life]].]]
*** Quite similarly, [[spoiler:Rolo's boss, V.V, the ReallySevenHundredYearsOld CuteShotaroBoy]], became psychotically devoted to [[spoiler:his younger twin brother Charles after their mother's death]] and [[spoiler:killed his sister-in-law Marianne, Charles's favorite wife and [[LadyOfWar his Knight]], out of jealousy]] when they started getting too close.
* Momo Hinamori, from ''{{Bleach}}'', is sweet and awkward and friendly... unless she thinks someone is responsible for [[spoiler: her captain's death]]. Just ask Gin, Kira, or even her childhood best friend Hitsugaya. In Momo's defense, though, [[spoiler: said captain was a ManipulativeBastard who ''deliberately'' played up on her natural loyalty to use her in his plans, making her a sort-of {{Tykebomb}} ever since he handpicked her from the best graduates of the Academy.]]
** Loly and Menoly, two Arrancar's from Aizen's army, are both very infatuated with Aizen. When Orihime attracts the interest of Aizen due to her powers, Loly and Menoly are shown getting incredibly jealous. Thus, they harass her, brutally beat her up, and even attempt to kill her, all while ordering her to "stay away from Aizen-sama!", [[spoiler: even though [[TheMessiah she]] healed them after Grimmjow brutally mauled them.]]
*** And later, during Ichigo's fight with Ulquiorra, they show up ''again'', torture Orihime, and try to kill her ''again''. When Ichigo notices this he charges after them in anger, and Loly threatens to [[EyeScream tear out Orihime's eye]]. She didn't get the chance to, but clearly wanted to, given her irrational jealousy towards the girl.
** Some fans theorize that Nnoitra Jiruga is a male subversion of this. He keeps on fighting Nel because he apparently hates her. It's more obvious, though, that he secretly likes her.
** And what about Rukia's Younger Sister [[spoiler: Homura]] from the third movie? She ''does'' want to kill all the Shinigami to keep them from coming between her and Rukia, after all...
* A subversion appears in a second season episode of ''JigokuShoujo''. A sweet young girl is deeply in love with the boy next door, and the girls at school call her a stalker for following him so closely, even now that he has a girlfriend. She seeks out the power of Hell so that she can... be able to take revenge. She's fine with the boy next door dating the other girl and is totally supportive of [[IWantMyBelovedToBeHappy whatever makes him happiest]], but she's going to hang onto the ability to damn someone to Hell just in case the other girl isn't so good for him after all. [[spoiler:The ReplacementGoldfish ending may have pushed her a bit further this way, however.]]
* L.A. from ''ElCazadorDeLaBruja'' That is all. Rosenberg [[AlternateCharacterInterpretation might also fit the bill...]]
* [[spoiler: Miyori, Aya Mikage's cousin and fellow Tennyo]] from ''AyashiNoCeres''. When [[spoiler: Ceres accidentally killed Miyori's beloved mother in her initial RoaringRampageOfRevenge]], she snapped ''hard''.
** Also, [[spoiler: Shiso Mikage mixes this and WithGreatPowerComesGreatInsanity]]
* ''FushigiYuugi'' had Yanderes of ''both'' genders: Yui Hongo is the female, Suboshi is the male.
* Nanami Kiryuu from ''RevolutionaryGirlUtena'', who generally presents herself as TheLibby, but drops into this whenever somebody takes her Big Brother's attention away from her. The most notable displays of this is when she tries to outright ''kill'' Utena during a supposedly formulaic duel, and when she kills a ''kitten'' that her brother Touga had taken to liking a bit too much. She's also proven willing to beat her 'troops' back into line, should they fail to obey her Libby Powers... we're not talking about just a couple of bruised cheeks here, but more like a trip to the hospital and several yards of bandages.
** Shiori also fits this trope. She seems like a kind, demure girl... At first. She is rapidly revealed to be very dark, selfish, and violent; harming people both bodily and mentally to get her way. She's even worse in the film version.
*** [[spoiler: It's not made clear until the last few episodes, but Anthy works with this trope too.]]
* Kazuki Ibuse, self-proclaimed girlfriend of the male protagonist of ''BitterVirgin'' acts like a normal, [[AttentionWhore if flashy]], girl in front of her desired beau, Daisuke Suwa, but is downright psychotic towards anyone who appears to stand between them. Such as the female protagonist, Hinako Aikawa. [[spoiler:To her credit, she's willing to (at least temporarily) give up when she realizes just how strong the feelings between the two leads are.]]
* [[spoiler:Faina Shinozaki]] from ''InfiniteRyvius''. When her boyfriend breaks up with her, she tries to kill him. When her previous boyfriend broke up with her, she ''did'' kill him. She also killed an old friend just for mentioning his name.
* Ash's Chikorita from ''{{Pokemon}}''. Whether it's just a desire for attention or flat-out romantic feelings varies from person to person. She gets over it eventually.
** In the new movie "Giratina and the Sky Warrior", the male Zero was very Yandere..About the ''Reverse World'', a world parallel to the normal Pokemon world. In this world, no one lives in other Giratina. [[spoiler: Oddly, Zero was out to destroy Giratina, by removing its ability to enter and exit the RW so that he could enter and exit the Reverse World whenever he wanted.]].
* [[SayonaraZetsubouSensei Sayonara Zetsubou Sensei]]: A whole class in which every single girl has some kind of mental instability. For example, one girl (Chiri) is manically obssessive compulsive to a point where she goes completely [[AxCrazy ax crazy]] if things aren't proper, one (Meru) is a [[CuteMute mute]] who starts [[BlackSpeech speaking in tongues]] if [[BerserkButton she is taunted while her mobile's mail function is unavailable]], as well as one certain girl (Kafuka) who, if the [[NightmareFuelStationAttendant occasional hint]] is any indication of her [[StepfordSmiler true]] [[BewareTheNiceOnes self]], might be [[KillEmAll the most dangerous one of them all]]. What do all these girls (arguably) have in common? Why, they're [[UnwantedHarem in love with their teacher, of course! ... The poor bastard.]]
** Matoi Tsunetsuki is the most obvious example of this, being his devoted stalker. Abiru Kobushi is the student most persistently used in this way beyond Matoi, not-so-subtly indicating a latent crush on her teacher on at least two occasions. As of a recent episode of Zan Sayonara Zetsubou Sensei, she believes she actually has such a relationship with her teacher, because of what his body-double got up to in his absence.
** Maybe I'm just reading too much into it, but there seems to be a kind of implicit "tension" between Zetsubou-sensei and Nami this season. To further read into the matter, after Abiru's day out with not-Zetsubou-sensei, she seems passively-hostile to Nami in the next episode, notably when calling her ordinary.
*** Don't forget her apparently strangling his stalker with one of her bandages in the background while he was lecturing Chiri about the dessert made by the sushi restaurant. [[MurderTheHypotenuse Eliminating the competition, perhaps?]]
** What about Mayo "She really is as evil as she looks, but everyone else simply assumes that she's misunderstood" Mitama? Like [[EvenTheGuysWantHim almost all of the students]] in Nozomu's class she has also developed a crush on him, but can only express her love through harming him.
* Belldandy from ''AhMyGoddess'' displays some of these tendencies, although they are quite mild. And they ''have'' to be, since [[BewareTheNiceOnes her self-control is the reason why she's allowed access to her ENORMOUS powers...]]
* Manami Anzai from ''Life'', who first appears as a cute and childish click leader who snaps utterly when she suspects Ayumu is trying to steal away her boyfriend. [[spoiler: she goes so insane that she then dates a gang leader on the side to use him to get back at both Ayumu and her boyfriend, and then promptly screws her boyfriend and the gang leader both over. Not to mention her vow to kill Ayumu with her bare hands...]]
* Prince Julius, CuteShotaroBoy and adopted brother/stepbrother of prince Ludwig in Kaori Yuki's ''LudwigKakumei''. HilarityEnsues when he creeps out his servants by laughing maniacally while surrounded by all the creepy manga effects existing in this world and the next. However, [[spoiler: SURPRISE, FOLKS! "He" is a true yandere girl, Princess Julianna!]]. But YUKI-ESQUE SURPRISE AGAIN: [[spoiler: Julianna was biologically male all along and was born as Julius, which also explains her lack of breasts. The manga strongly implies she's a {{Transsexual}} girl, but the other characters mistake her for a Cute Shotaro CrossDresser who's gay for Ludwig]]. HilarityEnsues, I say...
** Also note that the trope is averted in the case of [[spoiler: Lui's mother]], as it's obvious from the start that she's a genocidal nutcase.
* Another male: [[spoiler: Tokigawa]] from the BoysLove series ''''OkaneGaNai''.
* Yet another male example is [[MoeAnthropomorphism Russia]] (Ivan Braginsky) from ''AxisPowersHetalia''; he shows his affection to his subordinate Lithuania (Toris Laurinatis) by physically and emotionally abusing him. He's just [[PsychopathicManchild childishly sadistic]] to everyone else. And Heaven HELP you if [[MadnessMantra he starts chanting]][[http://s107.photobucket.com/albums/m292/Equivalential/hetalia4/?action=view¤t=03_02.gif "kolkolkol"]]...
**The yandere side of him seems to have evolved from a vicious mental beating over the course of centuries of bloody Russian history that resulted in a {{yangire}} breakdown known as Bloody Sunday 1905. It seems he ''was'' rather sweet and friendly, [[CloudCuckooLander though still]] [[CreepyChild pretty off kilter]], [[DespairEventHorizon up to that point]].
** And his Yandere habits have rubbed on others. Specifically, his sister Belarus (Nathalia Arlovskaya, a GirlWithPsychoWeapon who doesn't hesitate to break poor Liet's fingers when they go on a date) and shy, traumatised, male ShrinkingViolet ''and'' Lithuania's younger brother, Latvia (Raivis Galante).
*** Belarus is quite the {{Yandere}} variation by herself - and with this, she's a Yandere for [[BrotherSisterIncest her older brother]]. The reason why she treats the Baltic brothers so badly is that Russia spends too much time with them [[TheUnfavorite and gives her little attention]], so she's hurt and jealous like Hell - specially of the aforementioned Lithuania, who happens to have a crush on her ''and'' be Russia's "favorite". As a little girl, Belarus even shows jealousy towards her and Russia's own older sister, Ukraine (Katyusha Braginskaya), in the scene where she gives Russia the ScarfOfAsskicking he still keeps (though this can be seen as mere childish sibling rivalry, before Bela was even ''aware'' of her upcoming crush on her brother).
**** There has been [[FanWank some arguing]] about Belarus's status as a {{Yandere}}, though. On one hand, it's very clear from the start that the girl's fucked up in the head ([[ComedicSociopathy if hilariously]]). On the other, her love of Russia [[LoveMakesYouCrazy is the]] ''[[LoveMakesYouCrazy specific]]'' [[LoveMakesYouCrazy reason why she's nuts]].
***** [[http://i199.photobucket.com/albums/aa10/Zoragirl/BelaruslovesRussia.png Crazy indeed]].
** There are lots of fanarts that give Denmark the Yandere treatment, specially in his relationship with Sweden and, to a lesser degree, Norway. He's less of a tyupical StalkerWithACrush and more like a testosterone-pumped BoisterousBruiser who wants to fight his love intrests so he can subdue and dominate them. [[InterplayOfSexAndViolence Holy aggressive courtship, Batman]].
** Among the Asians, ChineseGirl Taiwan is occasionally made into a Yandere or a {{Yangire}} by the fandom, mostly for comedic effects.
** Spain has started to get the {{Yandere}} treatment among the J-Fen, to reflect the change he might have gone through in the Conquistador times. Pixiv (the Japanese equivalent of Deviant Art) has a tag dedicated solely to Yandere!Spain arts.
* Pretty much the entire main cast of ''HigurashiNoNakuKoroNi'' go AxCrazy occasionally, but they're more likely to be {{Yangire}}s. However, there is at least one true {{Yandere}}: [[spoiler: Shion Sonozaki, whose StartOfDarkness involved her old crush, Satoshi, and her feelings of abandonment when he "transferred."]] The arcs where she snaps tend to be some of the most disturbing in a show that has a [[HighOctaneNightmareFuel/HigurashiNoNakuKoroNi High-Octane Nightmare Fuel page to itself]], and even in the last arc, where everyone's sane [[spoiler:she gets very, very... ''intense'' when she finds out where Satoshi is.]]
* Kaorin from ''AzumangaDaioh'' might qualify for this trope, as it's hinted that she was prepared to injure her best friend in order to be in a three-legged race with Sakaki.
** Also seems to be an InvokedTrope in Osaka's famous [[http://media.photobucket.com/image/osaka%20knife/StardustCross/osaka_knife.jpg "knife scene"]]- compare the picture with the page image. Osaka ''probably'' isn't one, but part of her {{Cloudcuckoolander}} personality is the ocassional [[NightmareFuelStationAttendant morbid fixation]], but that doesn't explain the scary story she tells which involves her killing everyone, nor the PsychoSmirk she makes after finishing it.
* Yukako Yamagashi from Part 4 of ''JoJosBizarreAdventure'' is in love with Koichi and is determined to make him love her back. She kidnaps him and tries to hold him hostage until he loves her back. Koichi develops a stand and she decides to let him free rather than fight it. [[IGotBetter She gets better]]...sort of. She decides to pursue a more consensual relationship, though she is no less aggressive in her attempts.
* Another male example: Harry [=MacDoogal=] of ''OutlawStar''. Seems fairly normal in his first appearance, but [[LoveMakesYouCrazy goes insane]] [[TheDulcineaEffect pretty much as soon as he meets Melfina]].
* Meet Magari Tamao from ''{{Nora}}''; [[TheDitz ditz]], {{bishoujo}}, loving mother, [[KnifeNut knife-wielding]] crazy woman.
* Creed Diskenth from ''BlackCat'' follows the MagnificentBastard BigBad archetype and seems like your average calm, scheming villain... until he hears something about Train or sees Train. Then all hell breaks loose. He seriously loses all his cool and rationale when there's anything to do with Train, letting his jealousy and [[StalkerWithACrush obsession]] make him go out of his way to kill [[MurderTheHypotenuse anyone getting in the way]] of him and Train... including [[IfICantHaveYou making a serious effort to kill Train himself]], by the end. Luckily for Train, he's a little [[BadAss better]] [[ImprobableAimingSkills equipped]] to deal with a psycho stalker than most.
* Mitsuki from ''{{Doubt}}'' is of the yangire variety (although, if you're into [[ParentalIncest that kind of stuff]], you could say she's yandere for her ''father'').
* ''MahouSenseiNegima'' gives us Tsukuyomi, who [[StalkerWithACrush really]] [[PsychoLesbian has]] [[AttemptedRape issues]] regarding Setsuna.
* Athena, Hayate's first girlfriend in ''HayateTheCombatButler''. Uses psychological torture to control Hayate. [[spoiler:Until it's revealed that she's more of a tsundere than anything. She even happens to be stronger on the dere than tsun, amazingly enough. Hey, she even saved his life and had a mutual crush with Hayate. Unfortunately, he trusted his parents (this incident fixed that) who then pawned the ring she had given him. And then she got possessed by some sort of monster and yeah, things kind of went downhill from there. And then ten years later it happened again, except worse.]]
* ''{{FLCL}}'': Mamimi. [[spoiler: She gets better by the end though, and channels her energies into [[HotScoop a succesful career in photography]]. Falling out of love with Naota when [[ComingOfAgeStory he started to mature]] was painful for him, but [[CharacterDevelopment it was good for both of them in the long run]].]]
* Griffith from ''{{Berserk}}'' acted a ''lot'' like a {{Yandere}} towards Guts in the past. Especially noticeable in their battle before Guts left the Band of the Hawk. Telling Guts, "you are mine," and thinking, "do you really want to leave? This badly... you want to get out of my hands?! No way... there's no way! I will not permit it -- I will not let you go!" He is even shown considering his possible actions of attacking Guts, which culminates in thoughts reminiscent of an IfICantHaveYou moment, where he decides he'd rather attack Guts lethally than let him get away.
** Given what ultimately drives him over the DespairEventHorizon, this may also have motivated the two acts that drove Griffith over the MoralEventHorizon, namely [[spoiler:his betrayal and sacrifice of the Hawks to the Godhand and his rape of Guts's girlfriend/his former lieutenant Casca once he became Femto during the Eclipse]]. Make no mistake, this guy has some ''serious'' problems.
** And then there's how it's heavily implied that he decided to go visit Princess Charlotte and have sex with her ''immediately'' after Guts left out of frustration and depression. It's pretty obvious that he mainly did it ''as a rebound''. Disturbing, much?
* Henrietta and Elsa from ''GunslingerGirl''. ''Kind of.''
*''{{Kuroshitsuji}}'''s version of [[spoiler: Queen Victoria, to the point where she merges her body with that of her dead husband.]]
** [[spoiler:The actual Queen, though, [[http://en.wikipedia.org/wiki/John_Brown_(servant) probably not so much]].]]
** Also: Grell. The anime plays it as (attempted) RapeAsComedy, though. But in the manga, Grell comes off as just plain demented for Madame Red and then Sebastian.
* Negishi/Krauser from ''Detroit Metal City''. Usually rather meek and virginal, he tends to exhibit insane, violent thoughts and/or behavior, often prompting a transition into his Krauser persona, when he feels that his one-sided love for Aikawa is being threatened, while shifting back into a more 'dere dere' version when things are going well between them.
* In as much as a draconic hermaphrodite Duel Monster can be a {{Yandere}}, Yubel from ''YuGiOhGX'' fits this trope to a tee. S/he tortures and "kills" all of Judai's friends, possesses the object of his HoYay-implied interests, tries to cause TheEndOfTheWorldAsWeKnowIt, and does his/her very best to make Judai suffer as much as possible. Why? Because in a past life, Judai pledged to love only him/her, s/he's jealous that he's forgotten him/her in favor of his other friends, and an unfortunate trip through space has severely screwed up his/her concept of love and pain, leaving him/her unable to distinguish the two and having him/her believe that only through suffering can you truly feel love.
* ''TokyoMewMew'' gives us Kisshu, who goes from being a [[MadLove nuisance]] to a major threat to Ichigo, as his behavior and his mentality grows increasingly unstable as he continues his pursuit of her. At various times throughout the series, he out and out threatens and attempts to kill Ichigo's boyfriend Masaya and even Ichigo herself should she fail to agree to his wish of "becoming his".
* Shinji Ikari seems to grow into a particularly violent male {{Yandere}} towards the ending of ''{{Neon Genesis Evangelion}}'', at one point attempting to strangle Asuka when she refused his confession of his feelings for her. In addition to that take into consideration how [[spoiler: Naoko and Ritsuko]] acted in regards to their ex-lover, Gendo (who would ''arguably'' count as a male one, [[spoiler: in regards to his dead wife, Yui]]. To a lesser extent there's how Asuka acts whenever Kaji or Shinji are involved, quite the extension of her {{Tsundere}} personality...
* {{Fist of the North Star}}'s Shin. In the movie, Shin's reaction to his second-in-command gently suggesting that he should not let the army stay disorganized so he can search for Yuria is to ''put his fist through the man's heart''. Dayamn.
* Nova from ''MagicKnightRayearth''. She ''[[EnemyWithout is]]'' Hikaru, ''[[PsychoLesbian loves]]'' Hikaru, wants to ''[[BetaBaddie be]]'' Hikaru, and hates everything Hikaru loves because it keeps Hikaru from loving her and only her. "Be your own person" doesn't even begin to apply here.
* Jessiebell from the {{Pokemon}} anime. She has a [[WhipItGood WHIP]], people!
* The titular character from ''{{Pucca}}'' is a toned-down version of this, but the [[RapeIsOkWhenItIsFemaleOnMale implications]] remain there.
* [[GirlWithPsychoWeapon Hitagi Senjougahara]] from ''{{Bakemonogatari}}'' nearly stabs [[OrdinaryHighSchoolStudent Koyomi Araragi]] in the eye with a mechanical pencil after he so much as talks about another female using her first name without an [[JapaneseHonorifics honorific]]. And only stops once he screams, "Stop it! There's nothing guilty about it! I didn't mean it like I knew her well! I'm only devoted to you, Senjougahara!" Afterwards, when he comments that she'll kill someone, she promises that he will be her first and only victim. [[TheOnlyOneAllowedToDefeatYou Unless someone else kills him]], in which case, she'll kill his killer. How romantic.
**Don't forget [[spoiler: [[StepfordSmiler Suruga Kanbaru]], first-name girl in question. She's so [[PsychoLesbian bitterly jealous]] of Koyomi she tries to beat him to death ''twice''. She may also be a {{yangire}}, considering she beat up her classmates for teasing her.]]
* Koboshi from ''{{Pita-ten}}'' is a mild version of a {{Yandere}} in regards to Kotarou.
* Played for laughs (at times, other times it's just creepy as hell) with Lisa Fukuyama and Kosame in ''GirlsBravo'' in regards to Yukinari and Kirie respectively.
* Kaori Aihara in ''MamotteShugogetten''. She's much more saner than most examples, however.
* From ''WelcomeToTheNHK'', Misaki in the manga. She's much more innocent in the anime.
* Fumio Kirisaki from SaitamaChainsawShoujo: After being dumped by her boyfriend she declares ''"Alright, I'll kill him... Then I'll die."''
* ...How in the hell is ''{{Bludgeoning Angel Dokuro-Chan}}'' not here yet? Adorable little Dokuro violently murders the boy she eventually falls in love with ''multiple'' times a day. With a ''huge spiky club''. [[IGotBetter She resurrects him, though.]]
* Gopher from ''{{Soul Eater}}''. He comes across as a twisted, faithful, albiet slightly calm servant to Noah-- but once he gets jealous... Jesus Christ.
* Miyamiya from ''BambooBlade'' is something of a poster child for this trope; when she's around her boyfriend, she's a sweet, doting YamatoNadeshiko. Around everyone ELSE, she's a sarcastic, rough-talking {{Delinquent}} with a rather sadistic streak. So much so that when Coach Kojirou was [[{{Toku}} giving everyone on the team colors]], we see her flash a BattleAura that resembles that of [[ShowWithinAShow Blade Braver]] main villain [[NamesToRunAwayFromReallyFast Death Armor]].
** Miyamiya doesn't hold a candle to the nuclear holocaust of a yandere that is Sakaki Ura. The word "obsession" doesn't even begin to describe her secret infatuation with an actor named Takigawa Junya, who just so happens to be completely oblivious to Ura's existence. Then Ura discovers the object of her affection is in a sexual scandal with an actress he works with, and the yandere mode kicks off like the Wrath of God in a way that only Bamboo Blade could do.
* ''PandoraHearts'': Lottie, Will of the Abyss definitely.
** Gil's devotion to Oz has a pretty dark edge. Hinted early in; outright shown in chapter 33, where Vincent goads him into saying/resolving to kill anyone who hurts or snatches his master away from him - no matter who it is.
* Seimei from ''{{Loveless}}'' towards his [[BrotherSisterIncest younger brother Ritsuka]].
--> '''Seimei:''' You see, I just want to be loved by Ritsuka. But I'm so insecure. That's why I have to test his love. Is this normal?
--> '''Nisei:''' It's normal for ''you''.
* Liang-Qi from ''{{Canaan}}'' '''really''' takes this to HighOctaneNightmareFuel levels towards her "nee-sama" Alphard. It's later revealed that they are not even sisters, since Liang is Chinese, while Alphard is a Middle-Easterner. She's also pretty much always attempting to kill Canaan because she believes that Canaan 'changed' her beloved "Nee-sama".
* Queen Joukaku, Youko's predecessor, from TheTwelveKingdoms. While seemingly normal at first, she falls madly in love with her ''kirin'', Keiki. Already unstable from [[IJustWantToBeNormal the stresses of an empress job]] she never wanted [[TheWomanWearingTheQueenlyMask and didn't feel qualified for]], her jealousy made her snap, prompting her to [[GodSaveUsFromTheQueen exile and execute all other women in Kei in order to remove "competition"]]. Then, Keiki got struck with shitsudou, a deadly disease that strikes ''kirin'' when their chosen emperors rule poorly. Ultimately, she decided to sacrifice herself to save Keiki ''and'' the kingdom. [[ItGotWorse And that's when the civil war started...]]
* Anemone from EurekaSeven feels [[WellDoneSonGuy this way]] towards [[BigBad Dewey]]. [[spoiler: Thanks to her reciprocating the affections of her LoveInterest, [[LoveRedeems she gets better]]]].
* LethalChef Bianchi from ''KatekyoHitmanReborn'' goes into a homicidal rage whenever she sees adult Lambo who looks exactly like her deceased ex-boyfriend Romeo...who apparently died of food poisoning...She also has an unrequited crush on Reborn and is perfectly willing to eliminate anybody who has a 'bad influence' on him.
** Earlier on, Haru also had a thing for the [[{{Shotacon}} younger]] [[DevilInPlainSight 'angel-like' version of Reborn]], to the point where she even tried to destroy Tsuna [[CompletelyMissingThePoint in order to free Reborn from his influence]]. She later gives up on her crush on Reborn and falls for Tsuna after [[RescueRomance he saves her from drowning]].
* Genkaku from ''DeadmanWonderland''. Though whether he's {{Yandere}} for Nagi's [[InLoveWithYourCarnage carnage]] or Nagi himself depends upon your interpretation. It starts off a bit more subtle, with Genkaku seeming a bit too intense and obsessed with getting Nagi to join the Undertakers (along with an interrogation scene between the two, where Genkaku is shown licking the blood from Nagi's arm, after his hand had been cut off, and saying that Nagi's hand has become very "cute"). Followed by how he is shown getting incredibly turned on by Nagi killing some poor sap, saying that Nagi is a "red flower that has bloomed." After that, he later pretty much gives Nagi a love confession telling him that the murderous side of him was beautiful and exquisite, and that he loved him. (He even tries to kill Nagi, once Nagi makes it clear that he absolutely refuses to join him.)
** And that's not even mentioning how annoyed and angry Genkaku gets whenever he sees the possibility of a girl getting close to Nagi (in regards to Shiro, he is shown being extremely agitated, wondering what relationship she has with Nagi, and saying that Nagi never learns, and that he'll just have to punish him again (which he tries by attempting to have Shiro and Karako raped). In regards to Karako, he stabs her when she hugs Nagi, telling her, "Don't touch my carnage, you shitty girl"). And later, Nagi does a double suicide with Genkaku, holding him down so Ganta can kill him. Genkaku appears extremely happy, and calls Nagi his "savior". It's especially interesting to note that he was also the one that killed Nagi's wife in the beginning.
* Ryoki Tachibana from the manga ''HotGimmick''. He's utterly obsessed with Hatsumi and while he at first just wants her to be his "slave" he eventually makes her his girlfriend. She's reluctant about getting involved with him because he always seemed "scary" and she was genuinely terrified of him for a bit, due to an incident when they were younger where she suspected that he pushed her down the stairs. She gradually develops feelings for him, but still has moments where she feels extremely put off and scared of his overly possessive and violent nature. His violent obsession over her develops to the extent where he firmly states that she's not allowed to even ''think'' of/love any other guy except him, even if it's her ''own brother''. He also demands that she should keep conversations with all men under one minute, answer the phone on the first ring when he calls, show up at least an hour early to all dates, and often overreacts when a male's name is mentioned in conversation, even if it's just her little brother. If he happens to see her with another guy he tends to go off on a jealous rage and hit her. The worst part is: She actually [[{{Wallbanger}} stays with him at the end of the manga and agrees to marry him.]]
** [[spoiler: That has been changed, though: Hatsumi actually grows a spine and, in the novel ''Hot Gimmick S'' novel, she finally leaves him for Shinogu.]] [[AuthorsSavingThrow Phew]].
* Gilbert from ''KazeToKiNoUta''. Make sure to befriend Auguste at your own risk.
* The Goth-Loli sisters from ''TheWallflower''. They are four, [[{{Gonk}} incredibly ugly]] girls, who dress up in ElegantGothicLolita wear, and are extremely obsessed with the four main male characters. Their first appearance in the manga had them getting revenge on Sunako and Noi for being so close to "their men". Their attempts to get closer to their respective crushes culminated in them attempting to harm Noi for her close relationship to Takanaga and the others.
* Karasu from ''YuYuHakusho''. He's infatuated with Kurama and wants to own him. Therefore, he considers killing him slowly and painfully to be the very best and most intimate way to do so.
* Sakurako from ''SakuraGari'' is frighteningly possessive [[BrotherSisterIncest of her brother Souma]] and hates Masataka (who's in love with her) because he is the object of Souma's affections.
* Eliade from ''DGrayMan''. So very much.
** Justified, as she is genuinely in love with Krory, but is being driven crazy by the conflict this presents with her Akuma programming.
** Also, Road Kamelot. She's a psychopathic loli with a constant SlasherSmile on her face who sings about killing people, acts like an excited child, and [[MindRape messes with your mind to turn you insane]]. [[BloodLust She likes the taste of blood]], and often cracks into hysterical laughter when maiming people. Also, as well as possessing a number of creepy dolls, she herself can transform into a creepy doll. And she has a crush on the main character, which she expresses by, within an hour of each other, a) glomping and kissing him and b) trying to force him to kill his friends. (She even professed her love to him not long after stabbing him through his left eye with a sharpened candle and licking off the blood). And if ALL THAT wasn't enough it gets even creepier due to the fact that she is immortal so she [[spoiler: has in fact looked twelve years old for the past thirty-five years, which means that she's biologically forty-seven years old]] and [[{{Shotacon}} Allen is fifteen-years old]].
*** She has also shown signs of extreme sadism and enjoys causing/watching the suffering of others, especially if it's Allen who's suffering, which includes [[MindRape Mind Raping]] Lavi, one of Allen's friends, in order to get him to momentarily turn on Allen, killing an Akuma subordinate for no other reason then to anger Allen, and nailing Miranda’s hands to a clock while writing profanity on the wall in her blood.
* Yuna from {{Maburaho}} is one of these, or rather she morphs into one of these as the series progresses. It gets to the point where she threatens physical violence against Kazuki for merely being in the presence of other girls, even when he's only in their presence because they've kidnapped him.
* Belldandy from {{Oh My Goddess}} is said to be this by Urd, and has told Keiichi that she has a '''very''' bad jealous streak. However this is mostly informed ability, as we rarely, if ever, see or read about the consequences of said jealousy.
* Male example: Cho Hakkai from ''{{Saiyuki}}''. His [[{{Twincest}} twin sister/lover]], Kanan, was [[BreakTheCutie kidnapped, gang-raped, forcibly impregnated]] ''[[BreakTheCutie and]]'' DrivenToSuicide by demons; he was so throughly broken that went on a massive killing spree--murdering 1,000 demons of the same clan ''and'', in the manga, the ''entire'' village that stood around and didn't stop the poor girl's kidnapping. ''But wait,'' there's more! When confronted by a survivor who wants revenge, Hakkai freaks him out by offering his eye as penance---by '''[[EyeScream plucking it out of the socket]].''' And he runs into this survivor while muttering about wishing he could have Kanan's corpse. The series proper, starting a few years after this incident, usually lets him off with being a TeamMom with shades of creepy StepfordSmiler, but is it any wonder the other characters are ''freaking terrified'' of Hakkai?
* CuteShotaroBoy Maki in ''DarkerThanBlack''. He'd be a little creepy even if he was just a [[LackOfEmpathy sociopath]] with the power to make [[StuffBlowingUp stuff blow up]], but he also has a massive, crazy stalker-crush on his boss, Amber. Such an insane crush, in fact, that he [[NotSoStoic completely abandons]] the usual Contractor "[[TinMan emotionless]]" act when he finds the guy Amber's in love with, and tries to kill him even though [[spoiler:if he'd succeeded, it would have ruined Amber's entire plan, resulting in a genocide]].
* In one chapter of ''NightmareInspector'', there's a male example with the stepfather of one client, who is originally portrayed as much more gentle and helping than the girl's abusive mother, a rather sympathetic character. Then it turns out that he's actually the cruel one, so obsessed with the client's mother that he locks the young girl up to keep her from stealing the mother's love. He then tries to brick Hiruko's client into a wall, and when her mother stops him, he bricks her up instead and leaves her [[ALoveToDismember rotting arm]] sticking out, which he talks to while claiming she is 'all his now'. And then he bricks Hiruko's client up anyway.

* Wannabe from ''Wildguard: Casting Call'', a secretly powerless heroine desperate as Hell to hit the superhero big time and more than willing to hurt anyone who gets in her way. She also wears her costume all the time, even after the competition is over and she isn't actually superheroing anymore.
* Mercy Mayrock from Howard Chaykin's ''The Shadow'' miniseries. A former beauty queen turned game show host whose violent on-air meltdown ruined her career... until she met quadroplegic billionaire Preston Mayrock, [[spoiler:the real Lamont Cranston]], and married him. She's also completely obsessed with the Shadow (eventually attempting to rape him at gunpoint and telling him to keep his costume on) and is sexually aroused by nuclear weaponry and explosions.
* In DC's ''IdentityCrisis'', [[spoiler: Jean Loring, Ray Palmer's (the Atom) longtime ex-wife, has a nervous breakdown and becomes one of these for her ex-husband. While maintaining a facade of being contently divorced, she planned to put superheroes' families in danger so that all heroes (including Ray) would run to their loved ones, ending in the deaths of three people.]]
* ''{{Batman}}'' villain [[VillainousHarlequin Harley Quinn]] may seem cute, but anybody who gets between her & "Mistah Jay" will regret it... if they live long enough.
** Not that it's ever a problem since she's the only one crazy enough to date a MonsterClown who abuses her whenever he can. Though, they're not together these days and she's exclusively with [[LesYay Ivy these days]] .
** Didn't stop her from forming a sometimes-relationship (which may or may not be romantic, [[DependingOnTheWriter depending on who's writing]]) with Poison Ivy.
* Rosy the Rascal, the [[MirrorUniverse Anti]]-Amy Rose from the ''[[SonicTheHedgehog Sonic]]'' ArchieComics. Amy's a YamatoNadeshiko compared to her!
* The Venom Symbiote is a total {{Yandere}} for ''SpiderMan''. Its thought process can be summed up as "That bastard! How dare he kick me out! Didn't he realize how awesome I was?! Well screw him! I hate him, I hate him, I want him to die! He deserves to suffer for hurting me! But then... I won't have him! I know, I'll kill off everything he loves and then force him to take me back! Then it will just be us together 'forever'...
** It's even been lampshaded, once in Marvel Age Spider-man and in TheSpectacularSpiderman, both times Peter pretends to apologise and asking if it wants him to be its host again which it does, and both times Peter mentions it's acting like a jealous ex-girlfriend.
** Also take a look at the ''What If?'' take on ''The Other'' storyline. Peter doesn't come back to life and the symbiote ''immediately'' abandons its current host to merge with Peter's body, becoming a new monstrosity called "Poison". It wants Peter so badly it doesn't even mind that Peter is ''[[{{Necromantic}} dead]]''.
**On the flip side, Brock is this to the symbiote itself.
* Played with in YokoTsuno's story ''The Pray And The Shadow''. The Yandere is actually an adult man in his late 40's, Mac Nab, who as a youngster was spurned by his crush Lady Mary and showed up at her wedding to curse her and her new husband, Brian, and predict that they'd never be happy. Brian died within the year, Mary [[TheOphelia almost fell into madness]] and some years later died in an accident, and everyone blamed Mac Nab, who was barely able to clear his name yet was ostracized by the community, living alone in a small house and keeping a mannequin that looks exactly like Mary and wears her wedding dress. [[spoiler: The truth? William, Brain's brother and Mary's second husband, was the one who set her up for death and made it look like an accident, then brewed a XanatosGambit to kill Mary and Brian's daughter Cecilia so he could inherit her wealth. Mac Nab was still a {{yandere}} for Mary, but was actually focused enough to join Yoko's plans to save Cecilia and use the mannequin as a SpannerInTheWorks.]]
* [[GreenLantern The Violet Lantern Corps aka the Star Sapphire Corps]] represent [[ThePowerOfLove love]] -- a dark, dark take on it. The Violet Power Battery was created from the parasitic Star Sapphire crystal that specifically empowers [[WomanScorned females who have been unlucky in love]]. As a result, every member of the Corps is some unholy combination of ClingyJealousGirl, StalkerWithACrush, and {{Yandere}}. Not surprisingly they may also indulge in IfICantHaveYou and MurderTheHypotenuse behavior. [[OhCrap And they all have superpowers]]. And the embodiment of love (a being that serves the same function as [[BigCreepyCrawlies Parallax]], [[SpaceWhale Ion]], and [[DarkMessiah Black Hand]] to the Sinestro Corp, Green Lantern Corp, and Black Lantern Corp respectively)? It's called [[NamesToRunAwayFromReallyFast the Predator]]. SoYeah.
** Oh yeah and their main recruitment is they take AxeCrazy women and brainwash them with love
** So far there is a grand total of ''one'' member that isn't like this, Miri Riam thanks to her husband getting killed right in fornt of her how ever she is a bit of a NaiveNewcomer.
* Veronica Pace in ''StrangersInParadise''. After the BigBad's "suicide", her former chauffeur Veronica takes over the remains of her organisation, gives herself an EvilMakeover and begins to show signs of [[AxCrazy Ax Craziness]]. Before her defeat, she [[JustBetweenYouAndMe reveals]] that she did it all because she was obsessed with Katchoo.
* During Chuck Austen's run on Uncanny X-Men, Polaris got [[{{Flanderization}} turned into this]] over Havok, going so far as to threaten [[{{RelationshipSue}} his nurse]] with magnetically controlled scalpels ''the day'' she arrived in the mansion. Then when it turned out they'd [[{{AliensMadeThemDoIt}} been having a psychic affair]] during Havok's time in a coma, and Polaris got dumped at the altar, she went the IfICantHaveYou route and tried to kill them both ''and the wedding party''. Austen later attempted to [[{{AuthorsSavingThrow}} justify]] [[{{AssPull}} this]] by claiming that Polaris had been driven insane by being forced to watch the genocide caused by Cassandra Nova's Sentinels, but pretty much nobody bought it, and once he was off the title, later writers made ''big'' efforts towards putting Polaris back together and ignoring the whole relationship fuckery as much as possible.

[[folder:Film]]
* Male example-[[RockyHorrorPictureShow Dr. Frank N Furter]]. Sure, he [[AnythingThatMoves flirts with nearly everyone in the film]]. But, if [[BerserkButton he sees Rocky with ANYONE else besides him]], he goes into a jealous rage. Janet Weiss (SLUT!) had to learn this the hard way.
* Angelique in ''He loves me, He loves me not''.
* Rose Mcgowan's character Debbie in the movie ''Devil In The Flesh''.
* Gloria in the 2005 film ''Film/WeddingCrashers'' has traces of this.
** As does Samantha James in the movie ''JustFriends''.
* Little Esther Coleman, the Russian ''Film/{{Orphan}}'', loves her new Daddy ''[[LoveMakesYouCrazy very]]'' '''[[HighOctaneNightmareFuel VERY]]''' [[AxCrazy much.]]
* Bobby (played by Fred Savage) in the [[LifetimeMovieOfTheWeek TV movie]] ''No One Would Tell''.
* Cal Hockley in the 1997 movie ''{{Titanic}}''. He became increasingly possessive and violent towards his fiance Rose, and jealous of Jack, when Jack and Rose started spending a lot of time together. He had Lovejoy, his right hand man, outright stalk Rose to keep an eye on her and make sure she was not with Jack. He even framed Jack with robbery and made it so that he would be locked up in the ship's lower deck, ''knowing full well that the ship was sinking'', and when that didn't work, tried to kill both Jack [[IfICantHaveYou and Rose]] out of anger. (Though a deleted scene showed that he had Lovejoy go after Jack, wanting to have him kill Jack in his place.) Despite all that, he tried to find Rose later on, when they were both on one of the rescue ships, hoping to apologize, still wanting to marry her. Rose earned a CrowningMomentOfAwesome when she spotted Cal looking for her on the ship and turned away rather coldly, keeping her face hidden from his view. In her words, "that was the last time I ever saw him".
** Still, he does deserve some credit for saving the little Steerage-class girl -- sure, he was only using her to get on a lifeboat, but even with [[spoiler: First Mate Murdoch]] dead, he could've probably still bribed another Officer.
* Eve Harrington from ''AllAboutEve'' pretends to be like this. She's the sweetest, humblest, most helpful young woman you'll ever meet, and above all else, wants to work entirely for and with Margo and model her life on Margo's, as closely as she can manage. Heaven help anyone who stands in the way of these things.
* Glenn Close as Alex Forrest in ''Film/FatalAttraction'', whose [[MoralEventHorizon most infamous act]] gave rise to the slang term "bunny-boiler" to refer to a similar character type. Glenn Close as the ''Yandere'' was the one of reasons ''Film/FatalAttraction'' was popular in Japan.
* Before ''Fatal Attraction'' stole its iconic status, ClintEastwood's ''Play Misty for Me'' was the reference movie for this trope. Eastwood's first directorial effort has him stalked by an obsessive fan. Who can frighten even DirtyHarry and The Man With No Name? Why, it's Jessica Walter, a veteran TV actress normally so square you would expect her to wear a shoulder strap purse and sensible skirt in the shower or on the moon. The psychotically jealous Evelyn Draper was the performance of a lifetime for her, leading a generation to get creeped out whenever they heard the classic Johnny Mathis tune named in the title.
* In the 2007 film adaptation of ''SweeneyTodd'', Mrs. Nellie Lovett spends the movie jumping between swooning over her beloved "Mr. T" and gladly butchering his victims to make pie. This is consistent with her behavior in the stage musical. The yandere-ness, on the other hand, comes in [[spoiler:with her treatment of Lucy Barker, a.k.a. the Beggar Woman, and the way that she led Sweeney to believe that she was dead so that she could have him for herself]].
* In ''{{Audition}}'', the male lead holds an audition for a girlfriend/wife under the guise of an audition for a movie, only to have the girl he picks be a very, very creepy yandere. [[spoiler: One scene involves the girl putting needles in the victim's eyes, all the while making an almost cutesy sound while gently (agonizingly) taping them in. In short, she tortures him for misleading her into believing he would love only her, not for the fake movie audition. Very, very creepy.]]
** [[{{HighOctaneNightmareFuel/Film}} Kiiiiri-kiri-kiri-kiri-kiri]]...
* Madison Bell of ''{{Swimfan}}'', a Fatal Attraction story [[SettingUpdate set in high school in the modern day]].
* Anakin Skywalker. Enough said.
* The aptly-titled film ''Obsessed'' centers around this trope.
* "Big Brother Ma" from the 2008 Chinese film ''ButterflyLovers.'' At first you think he's just going to be the UnluckyChildhoodFriend of the tale. [[ItGotWorse And then the plot ensues...]]
* [[spoiler: Debbie Jellinsky]] from ''[[TheAddamsFamily Addams Family Values]]'', who earned the nickname "Black Widow" for murdering husbands who were too busy to give her the love she needed (it doesn't help that she, being a [[GoldDigger materialistic woman]], likes to marry men who have a lot of money, who usually have to work around the clock).
-->'''[[spoiler: Debbie ]]''': Sorry, [[spoiler: Debbie]], no Mercedes this year. We have to set an example. Oh yeah? ''Set THIS''!
** She also murdered her family via burning her house down for ''getting her the wrong Barbie doll''. Of course the whole thing is played for laughs.
* The FlyingBrick title character of ''My Super Ex-Girlfriend'' vows to destroy the protagonist's life after he breaks up with her. One memorable scene had her throw a shark into the bedroom of his new girlfriend after spending the night with her.
* The Other Mother in the movie ''{{Coraline}}''.
* Harriet from ''So I Married an Axe Murderer'', who becomes a bit unhinged after winning over Charlie.
** In a subversion, this is because [[spoiler: ''all'' of her previous husbands abandoned her and she's developed a complex -- or so she thinks. Turns out Harriet's ''sister'' was an insane {{Yandere}} for ''Harriet''. She murdered Harriet's husbands and faked their deaths to keep Harriet to herself and nearly does the same to Charlie near the end]].
[[/folder]]

[[folder:Literature]]
* In AgathaChristie's novel ''Literature/AndThenThereWereNone'', Vera Claythorne looks like a sweet and pretty governess and teacher. In reality, [[spoiler: she killed her pupil Cyril by letting him drown in the sea, so his uncle Hugo who also was ''her'' lover could inherit the kid's estate. Said lover was the only one who found out, but the incident had already been filed under "accidental death", so he left her and became an alcoholic out of guilt]]. As the plot advances [[spoiler: and all the people around her [[KillEmAll fall like flies, dying in ways similar to those depicted by the "Ten Little Indians" nursery rhyme]],]] Vera becomes more and more psychotic and crazy, full of remorse and slapped by her memories of the deal, [[spoiler: specially those related to Hugo's rejection of her]], and in the end [[spoiler: not only she kills Philip Lombard by taking his gun and shooting him, but in the end, she finds a sort-of scenario involving someone having to hang him/herself (also according to the rhyme), settled by the Mastermind behind this... and does so]].
** Averted in the play. [[spoiler: The ''uncle'' killed Cyril instead. As she isn't a murderess, Vera is allowed to live.]] Also, in three of the English-speaking movie adaptations: [[spoiler: she is accused of murdering her sister's finacee, but reveals towards the end that it was her sister who killed him; the sister's fate differs in each adaptation, however: She either dies, or lives in a mental institution. Whether or not the sister was the Yandere is debatable, as it was never fully explained beyond who was innocent or guilty.]] And in one adaptation, [[spoiler: all that happened was a child dying in her care and there is no reference to her lover at all.]] Only the Russian version faithfully keeps her original crime and character.
*** Actually, Agatha Christie seemed to be pretty fond of this trope for many of her female characters, mostly under the "deconstructing the [[YamatoNadeshiko Yamato Nadeshiko]] and examining it realistically" category, which was ''especially'' appropriate for the time period she wrote her novels in, when women were expected to be devoted to ''only'' their loved ones and have no other life of their own. This is [[DeconstructedTrope deconstructed]] ''so'' very much. Vera would have to be her most prominent example because she not only deconstructs it; she ''stomps all over it and rips it completely to shreds.''
* In RoaldDahl's short story "Lamb to the Slaughter", Mary Maloney acts the perfect wife... until her husband announces that he's leaving her. She then lashes out with the frozen leg of lamb that was going to be that night's supper, killing him unintentionally. She is heartbroken, but as she is pregnant, she will not run the risk of being caught; she feeds the murder weapon to the police officers who come to investigate.
* Elena from ''The {{Chronicles Of Thomas Covenant}}'' takes this trope to the next level by having a disturbing romantic obsession over her ''biological father''. Thanks to her, I will never look at the word 'beloved' the same way again.
* The Other Mother in NeilGaiman's ''{{Coraline}}''.
* StephenieMeyer's ''{{Twilight}}'': Edward Cullen, of course. [[StalkingIsLove Not that Bella minds though]].
* Hester Shaw from Phillip Reeve's ''MortalEngines'' quartet. After she sees her boyfriend, Tom [[spoiler: kissing Freya Rasmussen]] she [[spoiler: betrays the city of Anchorage to Arkangel, just to get him back]]. She'd also do anything or kill anyone for him. Or to get him back.
* The Lover in ''Porphyria's Lover'' by Robert Browning...the poem can be interpreted in a number of different ways, but the main gist of it is that he kills her so that he can make the moment last forever, and the poem closes with him clutching her corpse. Eep.
* [[TheVampireChronicles The vampiress Claudia]] shows signs of being both this ''and'' a {{tsundere}} for Louis. Besides her own anger, she's even willing to [[spoiler:'kill' Lestat]] so that they can be together. Of course, for [[ReallySevenHundredYearsOld certain reasons]], she prefers to experience the [[IfYouKnowWhatIMean physical side of the relationship]] vicariously.
* Seriously, we've gone this far without a mention of ''{{Misery}}''? Although this might be somewhat of a subversion, because the target of Annie Wilkes' attraction is a fictional character. Doesn't stop her from going AxCrazy when the author has different plans, though...
* [[PsychoExGirlfriend Selene]] of the WheelOfTime. Also known as[[spoiler: Lanfear, Mierin Eronaile, Cyndane, or the Daughter of the Night.]] She wants [[spoiler: Rand al'Thor]] ''very'' badly, has [[ClingyJealousGirl no tolerance for any woman who so much as touches him]], and [[{{Understatement}} gets very put out]] [[IfIcantHaveYou if he refuses her]]. It doesn't help that she is an extraordinarily powerful channeler and quite often [[ShootTheMessenger kills underlings]] [[BadBoss in the midst of]] [[UnstoppableRage her murderous rages]].

[[folder:Live Action TV]]
* Myra from {{Family Matters}}.
* Lorena from ''TrueBlood''. Even after Bill tells her multiple times that he hates her guts and can't stand the sight of her, she still has the nerve to ask him "When will we see each other again?"
* Chris Keller in ''{{Oz}}'' over Beecher. He kills every guy that Beecher sleeps with, (including the guy who murdered Beecher's father) has Beecher murder Schillinger unknowingly, acts overly aggressive with Beecher at times, on two occasions has knocked him out with a blow to the head when Beecher goes against his wishes and later handcuffing him to a chair away from other people where he forces a kiss on him, and finally murdering the Aryans so that they don't pose a threat to him or Beecher anymore.
** As well as Ryan over Dr. Nathan.
*** Claire Howell too, the typical PsychoExGirlfriend who has no qualms about beating up men who refuse her predatory advances, even practically raping some inmates on the spot, or going off on a jealous rage against Tim McManus, who she had been dating for a while when she sees him comforting Diane who had lost her mother.
* Rhonda, the child bride of the cult leader, on ''BigLove''. She trades shamelessly on her status as an abuse victim, right up to the point when she flips completely and flaunts her status as bride of the Prophet. She's willing to blackmail and manipulate, but she takes pains to appear as a sweet innocent to anyone she's not specifically attacking.
** Later on, she escapes from the compound and is able to adopt fame as being an escapee from a fundamentalist compound. Sarah tries to tell Rhonda's community worker about Rhonda's dark side tendencies [[spoiler: and is shocked to discover that the worker is well aware of them. She justifies them on the grounds that Rhonda grew up on, well, a ''polygamist compound'' and adapted them as a survival mechanism. Sarah is visibly shaken when she is told that Rhonda's attitude is more deserving of pity than scorn]].
* Lila from ''{{Dexter}}''. She had Dexter [[spoiler: ambushed in a parking lot by a man who wanted to kill him because she thought it would bring them closer.]] When Dexter dumped her, she [[spoiler:obsessively tried to win him back with methods including arson and framing one of his friends for sexual assault]]. Basically, she makes Dexter, a [[HeroicSociopath sociopathic]] ''{{serial killer}}'', look [[strike:almost]] sane.
* Miss Piggy from ''TheMuppetShow'' is an obvious one. Rather animesque in that, though she often randomly attacks just about everyone over [[RantInducingSlight any minor thing]], the one who she is ''really'' most likely to [[MegatonPunch Falcon Punch]] across the room is her "Kermie".
* This happened several times in ''BuffyTheVampireSlayer'', usually magically induced.
** In one episode, Xander used a spell that turned every female in town (except the intended target) into someone who desperately wanted him, to the point where they would cut him to pieces. This included UnluckyChildhoodFriend Willow, who at that point was a sweet, somewhat doormat-y personality, but was at the forefront of the 'chop Xander into pieces' crowd.
** In another episode, we learn about a student who shot his teacher/lover years earlier when their ghosts re-enact their deaths, possessing various students.
** In a third, some random student inherits a magic jacket that turns all the women ''again'' into love-crazed psychos, including Buffy, Dawn, and Willow (whose plan was to [[NoBisexuals turn him into a girl]]).
** Hell, normal Willow has definite Yandere tendencies. When Oz leaves her because an encounter with another werewolf makes him realise what a danger he could be in the 4th season, she almost performs a spell that would have made both and the other woman miserable for the rest of their lives (she backs out at the last minute), and later is disappointed that she didn't bewitch him into staying with her. Later, when she and Tara have a fight, Willow ''wipes her memory'', and when [[spoiler:Tara is killed]] Willow: [[spoiler:flays a man alive, kills another man who had little to do with anything, is determined to kill two people who had little to do with what she wants them dead for, and is perfectly willing to kill all her friends for getting in the way.]]
**Spike, Spike, Spike--a thousand times ''Spike''.
* Wesley is one of the most thoughtful and likable characters on ''{{Angel}}'' -- except where Fred is concerned. His obsession with her in the final two seasons is downright scary. In the two-parter where Fred is mysteriously dying, Wes kills a man without hesitation, stabs one of his best friends, and gives us this mind-boggling yandere moment:
-->'''Employee:''' I mean, the whole company can't be working Miss Burkle's case.\\
'''Wesley:''' Of course.\\
(Wesley pulls a gun out of his desk and SHOOTS THE EMPLOYEE IN THE KNEE.)\\
'''Wesley''': (to secretary) Jennifer, please send anyone else who isn't working Miss Burkle's case to me.
** Another example from the same show is Connor, [[OedipusRex Oedipus complex]] poster boy, who does more and more horrible things in season four out of love for [[spoiler:what he thinks is]] Cordelia.
* Masato Kusaka in ''{{Kamen Rider Faiz}}'' is a rare male example of this. He replaces the "cute, delicate, and sweet" facade with one that is strong, [[TheAce supremely competent]] and [[{{Bishonen}} handsome]], but his inner obsession with Mari fits this exactly.
* Reese in the ''StargateSG1'' episode "Menace" seems like a sweet, friendly (if a little spoiled) RobotGirl, but when things don't go her way with Daniel, she [[spoiler:creates an army of Replicators which proceed to nearly wipe out the SGC.]]
* Caroline, one of Fez's girlfriends in ''That70sShow''.
** Then subverted when Donna finally just snaps and tells her Fez doesn't love her. A little heartbroken, she asks Fez, who nervously and hesitantly admits. It is, in fact, strongly implied that she had completely snapped from the event, and directly stated that she had spent most of the intervening time on psych drugs and intensive therapy.
* [[HotForStudent Leslie]] turns into this after Billy dumps her on ''{{Soap}}''.
* Male example in the ''{{NCIS}}'' episode "Love & War": the murder of the week turns out to have been arranged by the ex-fiancee of the victim's daughter. She had resumed their relationship after her mother died of cancer, so after she broke up with him a second time, he arranged her father's death in the hopes that the hurt/comfort scenario would repeat itself.
* Barney from ''HowIMetYourMother'' says you can tell a girl is {{Yandere}} by seeing if she has "crazy eyes." He says this of a girl Marshall is going out with when he introduces her to the group. The entire episode is of Marshall wondering what Barney says is true with evidence piling up, but in the end it's revealed that it was the work of Lily, Marshall's ex-fiance. Marshall finds it endearing and they gets back together. The episode ends with previous girl proving to be Yandere after all.
* ''DesperateHousewives'' had [[spoiler: Orson's ex-wife who was believed to be dead]] in season three. Her story arc first makes her out to be the victim of the situation [[spoiler: before it is revealed that she disappeared and re-appeared for the sole purpose of getting revenge on Orson for not returning her love...by drugging him up and raping him. Because she wants to have ''his'' baby.]]
** Don't forget George, a pharmacist, who lusted after Bree once she ended their affair together and became jealous of her husband Rex. So he [[spoiler:tampered with Rex's prescription drugs by replacing his heart medication with placebos.]] He also beats up and attempts to kill other people who look like they are trying to come in between him and Bree. He also drugged Bree at one point and was seriously considering taking advantage of her. He eventually proposed to Bree and pressured her into marrying him. After the marriage he became increasingly possessive of her, and increasingly violent.
*** Katherine seems to be treading a fine line between this and being a StalkerWithACrush. Time will only tell whether or not she jumps into this.
* ''SmartGuy'' did an interesting take on this trope: In order to win over another girl, Marcus, with the help of his brother TJ, hacks into the girl's on-line diary in order to find out what she sees in a guy so he can become her ideal boyfriend. It backfires when he later on reads her diary entries and learns that she has become obsessed over him to the point where she wants to quit school and start a family with him. When he tries to break it off and flirts with another girl, she attempts to ''run over'' said girl, culminating in pig masks, [[AxCrazy axes]], and a chase around the house. The twist? [[spoiler: She and her friends, including Marcus' sister, Yvette, found out his ruse and planted fake diary entries just to teach him a lesson. Though you have to wonder how much of an inversion it is for someone to think acting like an AxCrazy to "teach someone a lesson" is funny...]]
* In ''Sons of Anarchy'' ATF Agent Joshua Kohn follows Dr. Tara from Chicago to Charming and engages in increasingly disturbing StalkerWithACrush behavior culminating [[spoiler:in an attempted rape/abduction that ends with his death]].
* Gloria Trillo from ''TheSopranos''.
* Quite a few ''PushingDaisies'' killers fit this mold, such as [[spoiler: Hillary Hundin]] from "Bitches" and [[spoiler: Shane Trickle]] from "Kerplunk".
* Male Example: [[spoiler: Henry]] from ''Harper's Island''. I mean seriously, [[spoiler: marrying someone just to get your half-sister onto the island, conspiring with your real father (John Wakefield) to kill everyone apart from Abby, '''killing''' him so Abby can live, and making it seem as if she and you died so you can start over?]] That is what I call obsessed. And just because [[spoiler: when they were younger, Abby said that she wanted it just to be the two of them.]] And when I say [[spoiler: younger]], I mean [[spoiler: elementary-age.]] Nothing that he should be getting obsessed over.
* Rose stalks Charlie in ''{{Two-and-a-Half Men}}'' and is just unbalanced enough that she could very well boil a bunny.
** To say nothing of Mel from ''FlightOfTheConchords''. She could give Rose a run for her money.
* Crystal (SummerGlau) in ''TheUnit''.
* Alicia Baker from Smallville. Though she gets better sort of when she comes back only to be killed off.
* Rigmor from Riget. She's throughly obsessed with Dr. Helmer, but as soon as she thinks he's cheating on her, she tries to kill him.
* A somewhat unconventional example, but Old Gregg from ''TheMightyBoosh'' is yandere for Howard Moon, alternately courting and threatening him constantly and within minutes of meeting him for the first time.
-->'''Old Gregg:''' I'm gonna hurt you.\\
'''Howard Moon:''' What?\\
'''Old Gregg:''' I like you. What do you think of me?\\

* Ella Gaines from The Magnificent Seven tv series.
* Consuelo (played by actress Paola Volpato) from the Chilean night [[SoapOpera telenovela]] "¿Dónde está Elisa?" (translation: "Where is Elisa?") is this. To NightmareFuelUnleaded levels.
[[/folder]]

[[folder:Music]]
* The character codenamed "Soror," from SoundHorizon's song "Ark," who kills the boy she loved (who was also [[BrotherSisterIncest her brother]]) for some "betrayal" unspecified in the song.
** The girl from "Baroque," another track on the same album, is a PsychoLesbian yandere nun (going by her costume in the live version, anyway) who also kills the girl she loves for rejecting her.
** And in "Stardust", Stella, an actress who's implied to be a WhiteDwarfStarlet, shoots her lover after catching him with another girl. "The bouquet in my left hand can't stop the impulse [read: gun] in my right..."
* Male example - the {{Vocaloid}} song [[http://www.youtube.com/watch?v=tiKZgymNqnk "Kaito ga UNINSTALL"]] involves Kaito going yandere for his "Master" and killing all the other Vocaloids out of jealousy.
** Don't forget Kaito's [[http://www.youtube.com/watch?v=wozCmwq0LZA Story About a Poor Rabbit]].
** There are also the yandere-themed fan Vocaloids, such as Taito and Juon Kiku.
* 'Two Sisters' by Clannad is about this.
--->Sister I'll not take your hand
--->And I'll have Johnny and all his land
--->And I'll be true, unto my love!
--->If he'll be true to me
* 'Two Sisters' is a version of the English traditional song "The Miller and the King's Daughter", aka "Twa Sisters", aka "The Bonny Swan" and probably a dozen other names. The elder drowns the younger "all for the sake of a man". In some versions, the younger gets her revenge from beyond the grave with the help of a musician. In others, the elder sister gets away scot free with the boyfriend and an innocent man is hanged for murder. In some versions, the boyfriend is not mentioned to have any particular wealth and the girls come from a royal family, so greed can be eliminated as a motive, leaving nothing but jealousy.
* "[=RoboCop=]" by KanyeWest.
* "Every Breath You Take" by ThePolice.
* "Over And Over" by ThreeDaysGrace, of which there is even an [[http://www.youtube.com/watch?v=u4Q5au9zfwg=related excellent AMV]] sync'd to [[{{Shuffle}} the tale]] of the lovely redhead once pictured above.
* The "singer" in Carrie Underwood's "Before He Cheats" seems to think she's allowed to smash her boyfriend's car with a bat because she ''thinks'' he MAY be cheating on her "with a bubble-headed bitch"... DoubleStandard ahoy!
** The best line is "the next time that he cheats... Oh, you know it won't be on me!" [[SelfFulfillingProphecy You got that right]]!
* To some extent, They're Coming To Take Me Away by Napole0n XIV.
* Played with in Pink's [[http://www.youtube.com/watch?v=ddZPrJ8ROto Please Don't Leave Me]], which starts off with the singer portrayed as a standard issue TheWoobie trying to keep her boyfriend from dumping her. Until he slips on marbles at the top of the stairs. The robotic head tilt she does looking down on him pretty much seals it. Madness, violence, and cute little hats ensue.
* Depending on its interpretation A Little Piece of Heaven by Avenged Sevenfold [[spoiler: in which the male singer either kills his girlfriend because he is afraid she'll reject his marriage proposal or because she does reject him (video and song have some disparity), then proceeds to preserve her corpse so she'll always be with him. Warning: Necrophilia!]]
* [[http://www.youtube.com/watch?v=Uxs1OZKkJ1M This song.]] That is all.
* [[http://www.youtube.com/watch?v=1ZsfpQP7SPw&feature=channel_page Henry Lee]] by Nick Cave and P.J. Harvey
* "Porcelain" by Better Than Ezra
--->I wish I could kill you, savor the sight
--->Jump into my car, drive into the night

[[folder:Myth And Legend]]
* Princess Medea, from the Greek stories about Jason and the quest for the Golden Fleece, is one of the oldest and most famous examples of this type of character. To "punish" Jason for leaving her for another woman, she puts her own children by Jason to the sword and kills Jason's new wife and her father with a poisoned robe. Thus, this trope is a lot older than any Anime, and could easily be renamed "The Medea", but isn't for parallelism with the sister trope, {{Tsundere}}.
**Not to mention to go with him, she killed her brother and chopped his body into pieces; throwing the pieces into the water ensured that their pursuit had to stop and gather them, as greek customs demanded that the body parts be buried together. (Or else you'll forever be missing that part)
**What about Hera?
* There is a Japanese folktale concerning a woman named Kiyohime who, when rejected by the object of her affections, turns into a dragon and kills him. [[http://en.wikipedia.org/wiki/Kiyohime More information]] can be found on TheOtherWiki.

[[folder:Tabletop RPG]]
* Lilith from ''{{Exalted}}'' is a rare sympathetic example. She ''was'' normal and sane, but was [[MindRape mentally tortured]] by her [[CompleteMonster absolute horrifying monster of a "husband"]] [[VillainWithGoodPublicity Desus]] so ''badly'' that she [[BreakTheCutie shattered]] into a mental, slightly AxCrazy wreck who was basically a sad little puppet for Desus. By the period the game takes place in, she's recovered - [[TheOphelia somewhat]], and this is after going feral and living in pure chaos for the better part of ''two thousand years'' - although she tends to understandably explode into a frothing rage whenever she sees something related to Desus-which is unfortunate for Desus' reincarnation, [[AmnesiacDissonance Swan]], who, while not a ''hero'' exactly, is still a ''lot'' better person than Desus ever was.
* The Galateids from ''PrometheanTheCreated'' tend to have this as their [[UnstoppableRage Torment]]. Seeing as they embody [[FourTemperamentEnsemble the sanguine humor]], their periods of Torment tend to involve giving into murderous obsession over others; the book lists the example of abducting an unrequited lover's girlfriend, holding her at knifepoint, and demanding the lover choose between the two.
[[/folder]]

[[folder:Theater]]
* Abigail Williams from ''TheCrucible'' fits this trope like a glove. After her boss John Proctor ends their affair, Abigail jumps at the opportunity to have his wife Elizabeth arrested and executed for witchcraft. [[spoiler: It backfires ''big time''. Elizabeth's pregnancy keeps her from being executed; John takes the blame upon himself and chooses execution over admitting witchcraft and losing his land, which would leave his family homeless.]]
* ''ThePhantomOfTheOpera'': Erik, the titular Phantom over Christine.
* Jackie-O from The House of Yes. [[spoiler: She kills her twin brother, whom with she has been having an incestuous relationship for most of their lives, when he attempts to regain a life of normalcy with his utterly average fiancee.]]
* Canio from ''{{Pagliacci}}'' [[spoiler:learns that his wife Nedda is cheating on him, and loses it. At first, the audience thinks he's giving a very emotional performance, but soon realize this is for real. Canio kills Nedda and Silvano and givea a BondOneLiner.]]

* Alma from the ''FirstEncounterAssaultRecon'' games, toward Beckett.
**To the point that she repeatedly [[spoiler: attempts to rape Beckett]], and at the end of the game, [[spoiler: finally succeeds.]]
* Bloody Mary of Twisted Metal: Black. Whats interesting is she doesn't have a specific love, but desperately wants a husband. And by desperate, I mean she stabbed her friend in the stomach on her friends wedding day, then put on her wedding dress and kept it on for 2 years, bloodstains and all. She's in the contest to get her dream husband, but when he tells her he'll never love her (despite being lobotomized by Calypso), she goes literally axe crazy on him, then drives into the sunset, looking for her mr Right, "even if [she has] to go through every man, one by one"
* In many of the MultipleEndings of the {{H-game}} ''SchoolDays'', one or more of the girls goes completely over the edge when [[ClingyJealousGirl the lead picks someone else]]. This doesn't happen ''all'' the time, and there are even some [[TenchiSolution harem endings]], but the yandere endings are the most famous, especially one involving a [[GirlWithPsychoWeapon saw]].
** The ending to the anime, though, is a straight example: [[spoiler:the pregnant Sekai stabs the lead character Makoto to death, and her rival Kotonoha later kills Sekai ''and cuts a hole in her body'' to see if she was pregnant at all, then cuts Makoto's head off and leaves with it on a [[MemeticMutation NICE BOAT]].]].
* In the {{visual novel}} game ''{{Tsukihime}}'', there's a rather chilling example of a less romantically inclined (at first, that can change depending of your choices) Yandere coming completely outta left field the first time you notice it. Spoilered because it will ruin a lot of the Far Side of the Moon stories: [[spoiler: I'm talking of course of the seemingly cute and funny ''meido'' Kohaku, who underneath her cheery facade has managed to kill all her emotions (effectively becoming an EmotionlessGirl), experiments dangerous drugs on people without losing the smile, and is plotting the extermination of the family she's serving because of the abuse she had to go through as a kid]]. Of course, if you ''pick'' her and manage to get her to come to grips with herself, [[spoiler:your sister Akiha]] then goes insane. Apparently insanity can not be destroyed, merely transferred.
** And then there's [[spoiler: [[IsntItSad Satsuki "Sacchin" Yumizuka]]]]. After she [[spoiler:becomes a vampire]] in the Far Side routes, she [[spoiler:sucks the blood of the innocent... mostly to survive, but also]] so that she can understand Shiki's "scary side" and be with him forever. When he refuses, she attempts to [[spoiler:make him one of her brainless minions]]. Yikes.
** An odd example is [[spoiler: [[BigBad Roa]].]] Who'd spent so much time devoted to his research, he failed to recognise his own obsession with the White Princess, even as he tricks her into drinking his blood, bonding them forever, and at the same time sending her AxeCrazy, causing her to kill her handlers and giving her the freedom to choose her own life.
** Pretty much everyone except Shiki, Hisui and maybe Ciel. Arcueid? [[spoiler:She's damn scary in Ciel's route.]] Ciel? [[spoiler:She tries to set up a sort of double murder/suicide plot with Shiki, but ummm that's her own route so lets say she mostly copes. She gives up completely with only mild hints of how she feels/her backstory in Arcueid's route.]] Akiha? [[spoiler:Goes from ClingyJealousGirl throughout the game to as scary as Arcueid in Kohaku's route.]] Kohaku? [[spoiler:The final straw in her utter craziness is Shiki's failure to recognize her as the girl at the window who gave her the ribbon.]] Roa? [[spoiler:The last 800 years of his history and [[LoveMakesYouEvil Arcueid's backstory]] is actually because he [[LoveMakesYouCrazy loved]] her.]] Satsuki? [[spoiler:IsntItSad?]]
* [[HeroicSociopath Princess Sapphire Rhodonite]] from ''{{Disgaea}} 3'' quickly takes a liking towards Almaz, Mao's [[strike: bitch]] "test subject." Almaz doesn't mind much, seeing as he's always had a crush on her (and because [[ChewToy it's the only remotely good thing that happens to him]]), but let's just say she has [[PoisonousFriend very interesting ways]] of trying to help him out of his predicament. Fortunately, Almaz himself is usually safe from her violence-happy ideas. Usually.
-->'''Sapphire:''' Of course, I might've just gone back to slash you to pieces to vent my anger. You saved your own life. Heehee [[SayItWithHearts <3]]!

** Her interesting ways of helping Almaz are because she's closer to an AxCrazy MamaBear than a true Yandere (remember that MamaBear can apply to the boyfriend as well).
** There's also Anise the cat witch.
* Oichi from ''SengokuBasara'' ends up as a Yandere in her Story Mode, but not because her husband Nagamasa was cheating on someone. Because he was KILLED in cold blood. [[spoiler:Then, she slowly (and tragically) transforms from a meek woman into a dark monster (in other words: slowly possessed by her own dark powers), and ends up killing her husband's killer, her brother OdaNobunaga ([[CardCarryingVillain a certified SOB]]) as well as [[KillEmAll all his subordinates]]. Then, after all those tragic trips and [[MyGodWhatHaveIDone realizing the atrocities she has caused]], [[TearJerker she got killed as she cried in agony.]]]]
* Leviathan of the ''MegamanZero'' series takes a sexual thrill in fighting Zero. Talk about FoeYay.
* Occasionally, the fandom of ''{{Touhou}}'' portrays [[BadassBookworm Alice]] as this, going beyond the usual {{Tsundere}} portrayal into seriously [[NightmareFuel creepy territory]]. Highlights include attempting to put [[KleptomaniacHero Marisa's]] soul into a doll to keep her forver.
* Some sectors of the ''[[BaldursGate Baldur's Gate II]]'' fandom see Aerie like this. She has the tendency to go somewhat overboard (insulting Jaheira's dead husband? Classy.), but she never actually ''does'' anything. [[MurderTheHypotenuse Haer'Dalis, on the other hand...]]
** One might ask how it is a "tendency". In the above example, she was at the absolute height of her despair over not being able to adapt to life without wings, and Jaheira butted in with her umpty-umpth "stop trying to get sympathy with romantic overtones from the player character (because ''I'' want to do that, though I won't admit it no matter how glaringly obvious) and be a man, girl!" line. As a result, Aerie spoke the single most unkind line she ever does at any time. It's understandable this line would stand out because it's way out of line (though still understandable), but considering how unique and strain-induced it was, it's hardly the character-defining moment some make it out to be.
* In the first two storylines of ''FateStayNight'', Sakura is a sweet and gentle UnluckyChildhoodFriend without a violent bone in her body. But in the third, where she's pushed just that little bit too far...
**I'm not convinced she's really a Yandere. Whilst she is clearly in love with Shirou, and will do anything ''for'' him, she doesn't do anything in particular to try to get him. As her normal self, if anything she pushes him away, to protect him. The [[spoiler:dark version of her doesn't seem to care all that much about him at all]].
** Also Gilgamesh, though it's mentioned in passing that while he was always a possessive egomaniac, [[spoiler:the tainted grail blew away any sense of proportion or morality he really has.]] So, he has a rather... strange... way of showing his affections to Saber.
* In Yoshine's route in ''BrassRestoration'', [[spoiler:Koutarou]] verges on this.
* The UpdatedRerelease of ''YggdraUnion'' has #367, a ShrinkingViolet ExtremeDoormat [[spoiler:test subject]], who's a ''yangire'' rather than a ''yandere''. She's meek, submissive, shy, and uncertain... until [[spoiler:the High Servant jacks her synchronization with her synthetic Diviner]], putting her body and mind under intense stress. Instant AxCrazy. Truly, WithGreatPowerComesGreatInsanity.
* Really Ryez from ''TwinkleStarSprites'' is yandere for Arthur Schmitt. Her favorite word is ''[[JapanesePronouns onore]]''.
* Sakura of ''DaCapo'' is very, very dere towards Junichi but as the story continues, psycho personality traits emerge more and more frequently, starting with the implication she ''dropped a tree branch on someone's head'' because they mistook her for the lead's younger sister and treated her like a kid. She gets worse, both in [[BewareTheNiceOnes back]] and [[LaserGuidedAmnesia main]] [[MurderTheHypotenuse story.]] [[spoiler:To be fair, she can't really help it as stuff just ''happens'' when she thinks about it.]]
* [[TheOjou Mitsuru]] from ''{{Persona3}}'' has a particular StalkerWithACrush with overt {{Yandere}} tendencies. [[SchoolGirlLesbians This girl]] stands outside the assembly room for the Student Council (of which Mitsuru is president) ''all day'', is obsessed with everything Mitsuru does, threatens to kill you if you don't cough up [[{{Fanservice}} swimsuit pictures]] of her after the BeachEpisode, and innocently asks if members of the Student Council would be replaced if... ''something'' were to happen to one of them. Oh, and upon learning Mitsuru rides a motorcycle, she says she would be thrilled to be ''run over'' by those "burning wheels of LOVE!"
** In ''{{Persona4}}'', there's an NPC outside the library who has a crush on an upperclassman. When she suspects that he has a girlfriend, she snaps at him and drives him away. Towards the end of the game, she places all the blame on the other girl and even tries to kill her through indirect poisoning.
* [[spoiler:Mithos]] of ''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 [[UncannyValley 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 tells him 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.''
* ''DragonQuestVII'' has Kaya, a cheerful maid who's fallen in love with her rich employer's son, Iwan. Unfortunately, they're also caught up in a complex LoveDodecahedron... While Kaya initially comes off as the only one who isn't {{Wangst}}ing and/or being an unhelpful {{Jerkass}}, instead working towards a solution, towards the end, she cracks a joke about ''poisoning everyone in town''. While everyone is eating at a feast ''she'' prepared. Later on, you find out [[spoiler: she wasn't joking about poisoning people, though she's narrowed her focus to a single target: her husband.]]
* Jin Kisaragi is another male example, and dangerously skirt with {{Yangire}}. 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. Then there's the final boss Nu-13, who is usually robotic with everyone else, but if she meets Ragna, she also becomes a crazed lovestruck and tried to have him and when Ragna refused, she [[IfICantHaveYou attempts to kill him]]. [[spoiler:Then you realize that Nu is based on Ragna's sister. [[BigScrewedUpFamily God, it sucks to be Ragna!]]]]
** And when Nu and Jin meet, and Nu loses, well...
-->Jin: '''You're never going to touch my brother again, you bitch! HAHAHAHAHAHAHA!!!'''
* Happens in Mitadake High. Like one time where the Yandere turned out to be the killer. "If I can't have you no-one can" does not BEGIN to describe what happened.
* ProfessorLayton's [[spoiler:Klaus]] is sweet and polite in his mannerisms, and especially helpful to those in need. At least, until he has the eponymous character on his own. Double points for being voiced by Oguri Shun, who has also portrayed ''[[DetectiveConan Kudou Shin'ichi]]'', an AmateurSleuth who absolutely despises this kind of character, in a live-action drama.
* IrisuSyndrome
* Catalina of ''GrandTheftAutoSanAndreas'', particularly as she starts getting closer to C.J. As if she weren't already [[AxCrazy crazy enough]].
** Both her yan and dere sides could as easily have been manipulative acts, evidence by how quickly and easily she turned off to him and moved on to the next thing (Claude, who she soon used up and threw away as well.) Criminally insane, surely; yandere, not so much.
* Sasha of [=~inFamous~=], the leader of the Reapers and the first {{Supervillain}} you fight is obsessed with Cole, whispering maniacal pleads for his love into his mind when he comes into contact with the sludge she controls. It might have something to do with the fact that [[spoiler:she was [[BigBad Kessler's]] former lover and Cole is actually an AlternateUniverse version of Kessler.]]
* Nuwangi in {{Utawarerumono}}. Sure, he ''is'' also an arrogant {{jerkass}}, but most of what he does is out of either desire for Eruruw or wanting to destroy Hakuoro. It's hinted from time to time that if the situation weren't what it was he wouldn't be as much of an ass. He's definitely not happy about what happens to Tuskur.
*[[spoiler: Wendy]] from {{Rule of Rose}} going as far as [[spoiler:killing Jennifer's dog Brown because she wants Jennifer all to herself. If that isn't bad enough, she also gets a serial killer to come to the orphanage when the other orphans abandon her. It backfires of course.]]
* In the [[NancyDrew Nancy Drew]] game ''Stay Tuned For Danger'', [[spoiler: the culprit is the rare ''male'' variety in the form of Dwayne Powers, whose motive for sending death threats to, and trying to kill, Rick Arlen comes directly from Rick dating the actress Dwayne is secretly in love with.]]
[[/folder]]

[[folder:Webcomics]]
* April from ''CollegeRoomiesFromHell'' starts out as the conscience of the cast, but her sanity unravels as she is [[CannotSpitItOut unable to articulate a crush on a friend]]. The joke is ultimately on her: Her rival in love, Marsha, is twice as madly possessive as she is, and handy with a knife.
* Eri-chan in ''OkashinaOkashi''. Ironically, she ''pretends'' to be {{Tsundere}} (rather unconvincingly), in furtherance of a typical {{Yandere}} obsession.
* 95-tan of the OS-tans, a 2chan meme who are {{Moe Anthropomorphism}}s of operating systems. Normally quiet and shy, when she sees Mac-tan, she brandishes a katana and tries to kill her.
* Oasis from ''SluggyFreelance'' is generally "giddy as a schoolgirl", but will kill anyone or [[http://sluggy.com/daily.php?date=000425 anything]] that stands between herself and her love Torg.
** Also of note, during Chapter 18's The Love Potion, Gwynn accidentally whips up a Love Potion which is a little too strong. Dex, Crystal, Riff and Bunbun all become Yandere to a certain extent for the duration of the spell.
* ''TsunamiChannel'''s "Experimental Comic Kotone": A trio of females is a bit ''too'' convincing [[http://www.tsunamichannel.com/index.php?date=2006-11-20=ExCoKo at cosplaying as]] [[{{Shuffle}} Kaede Fuyo]], [[HigurashiNoNakukoroni Rena Ryugu]], and [[SchoolDays Kotonoha Katsura]], all of whom have already been mentioned on this page (and one of whom had her picture at the top for the longest time). Now ''that's'' a scary encounter...
* Both Becca and Zoe from ''FletcherApts'' fall under this trope. At one point they have a vicious CatFight over Bill and it has to get broken up by CoolBigSis Lori.
* Curio from ''TemplarArizona'', under her cute and bubbly exterior, turns crazy and weird not even over a love interest, but over ''friendship'' interests.
* Zimmy from ''GunnerkriggCourt'' does this to her only real friend Gamma, to the point she "translates" other people's words (Gamma doesn't speak English) to make Gamma think everyone else hates her.
* Fuschia in ''{{Sinfest}}'' is a borderline case played for sympathy and laughs. As Nique put it, "Criminy, you have a secret admirer slash [[StalkerWithACrush stalker]] from [[{{Succubus}} hell]]."
* [[http://www.misfile.com/?page=1383 It was recently revealed]] that this is Heather's motivation in ''{{Misfile}}''.
[[/folder]]

[[folder:Web Original]]
* Doki from ''ThereSheIs'' starts as a fairly minor example of this: She does chase Nabi around the city and can't take "No" for an answer, but otherwise doesn't seem to be all that crazy or violent. Her love craziness reaches its apex midway to Step 3, until she becomes saner, but only after Nabi agrees to become her boyfriend.
* The character of Rift from ''{{New Vindicators}}'' seems like your usual young teacher/superhero until her obsession with Michuru comes out. Then people start dying.
* ThatGuyWithTheGlasses is a male example. He's calm, friendly, even charming, as long as you just listen to the tone instead of the words.
* The Starfish from the third ''CharlieTheUnicorn'' video.
** "STARFISH REALLY LOVES YOU!"
** "LOVE ME, LOVE ME!"
*** "I WANT TO BE WITH YOU FOREVER!"

[[folder:Troper Works]]
* Tsugumu and Tsukiyo from [[{{TroperWorks/KIKEN}} KIKEN]] and [[EPICOretachi EPIC! Oretachi]]. The latter is a very CheerfulChild, while the former's cheerfulness almost borderlining on [[{{Keet}} Genki Guy]]. They cannot handle it if ever anyone is pursuing each other, especially due to a mutual BigBrotherComplex--yet the both of them are twins.
** Tsugumu, in [[{{TroperWorks/KIKEN}} KIKEN]] nearly kills someone because he drove Tsugumu'ss elder brother and twin sister to comatose states, yet reconciles with the murderer after the both of them wake up from their comas. Especially with hugging.

[[folder:Western Animation]]
* Missy from ''NedsDeclassifiedSchoolSurvivalGuide'' towards the titular Ned.
* Gaston in ''BeautyAndTheBeast'' becomes a male version of this towards Belle.
* Lizzie from ''[[KidsNextDoor Codename: Kids Next Door]]'' is Nigel's {{clingy jealous girl}}friend, who can go from [[{{Kawaiiko}} sweet and cutesy]] into an UnstoppableRage in seconds when things don't go her way. Oddly enough, ''she's'' the one who [[spoiler:breaks up with Nigel.]]
* Berry from ''FostersHomeForImaginaryFriends'' totally fits this trope, acting sweet and kind, but being homicidally jealous of anyone who she perceives as a threat to her relationship with Bloo, which is even more imaginary than she is.
* The titular character of ''{{Pucca}}''. She's smitten over Garu, but since he thinks GirlsHaveCooties, he's not having any of it. ''Ever.''
* Panini on ''{{Chowder}}'' is obsessed with the title character, to the point where it's scary at times.
* Wendy, Stan's love interest/girlfriend in early seasons of ''SouthPark''. She went so far as to have a substitute teacher arrested on false charges and locked inside a rocket launched directly at the sun, for the crime of having been the object of a brief crush from Stan.
* Quagmire marries one in ''FamilyGuy''. Peter convinces him to get a divorce using champagne and Lois's breasts, and when he tries to broach the subject she threatens to cut herself with a kitchen knife and then cut him.
** Meg is Yandere for Brian in "Barely Legal".
** Stewie has also shown to be quite the {{Yandere}} towards whoever he may express an attraction to or fall in love with, [[DepravedBisexual male or female]]. What with his "marriage" to Olivia in "Chick Cancer" during which he became possessive of her to the point of expressing jealousy at her friendship with a successful child actor named Victor. When he caught them hanging out without his knowledge in his and Olivia's cardboard house, he quickly ran outside, barricaded the door, and set the house on fire, with Olivia and Victor still trapped inside. He's also shown to be quite aggressive towards Brian, making blatant sexual advances, even brutally beating him up on two occasions for not paying him some bet money, despite being attracted to him. He even tried to deliberately come in between Brian and Jillian in one episode, with the intention to break them up.
** There was another instance when he became attached to Lois after she saved Rupert from a dog, and he got visibly angry when Brian told Lois he made some coffee for her. He threatened Brian, telling him that he didn't want him to talk to Lois anymore, that he was tired of him hitting on her, and that Lois was "his woman". He also resorted to rather extreme measures to get Lois's attention when she began to ignore him, like emptying a bottle of pills, spraying shaving cream around his mouth, and laying on the bathroom floor, trying to make it seem like he had gotten sick from "accidentally eating these pills that looked like candy", and shooting some bullets into his ceiling out of anger with a rifle when Lois refused to let him sleep next to her in her bed.
** Finally, one episode had him crushing on his babysitter Liddane. He became incredibly angry when he discovered that Liddane already had a boyfriend named Jeremy, which he expressed by insulting him in front of Liddane and declaring that Jeremy "must be destroyed". He later breaks into Jeremy's house before the latter gets home, leaves a drawing depicting him and Liddane happily holding hands in love while Jeremy is dead and departing to heaven. He then attacks Jeremy with a tire iron in a jealous rage, ties him up, and locks him him in the trunk of Brian's car. Also, after Liddane scolds him for touching her breasts, Stewie gets mad at her for rejecting him, drugs her, touches her breasts, and frames her by littering the house with beer bottles and trash, telling Lois that she held a wild party and everybody was taking drugs and "touching each other". His actions get Liddane fired though he later regrets this once she gives him a mix tape, mourning that Liddane was his "soul mate".
* During one episode of ''TeenTitans'', Starfire shows a few Yandere tendencies when [[BrattyTeenageDaughter Kitten]] blackmails Robin into going to her high school prom with her. At one point, she crushes the front end of a car with a single punch. However, this isn't brought up again later.
** Of course, Kitten is probably enough to induce this in anyone, given how bloody ''annoying'' she is.
* In one ''LooneyTunes'' cartoon, Daffy must exorcise a possessed heiress, though there's open room for interpretation that she was actually one of these.
* ''{{Avatar The Abridged Series}}'' makes one out of the one-off character Meng.
* Captain Hero from ''DrawnTogether''.
* "Cynthia", the RobotGirl from the ''BatmanBeyond'' episode "Terry's Friend Dates a Robot".

The original fanfic was supposed to have ended with him having her committed to an institute to save his own life.
* ''GoodOmens'' DarkFic ''[[{{Fanfic/TheSacredAndTheProfane}} The Sacred and The Profane]]'' when Caphriel confronts Zirah about a certain killing spree his response is along the lines of: ''[[PoisonousFriend What it was your idea!]] [[LoveMakesYouCrazy Don't you understand, I did it for you!]] [[PsychoSupporter Isn't this was what you wanted?]]''
