History Main / PsychoLesbian

* SerialKiller Catherine in ''Black Widow'' (1987). Though she seduces, marries and murders wealthy men (ostensibly for their money, but long past the point where she would already be rich) there's a definite lesbian subtext with the female Justice agent pursuing her.

* Jennifer from ''Film/JennifersBody'' (2009) can be interpreted as being romantically attracted to her best friend [[HollywoodHomely Needy]]. When she becomes possessed by a demon and starts eating people, she specifically targets boys who Needy likes or loves.

* In ''Film/{{Matilda}}'', the Big Bad is a sadistically evil, authoritarian, and athletic monster of a headmistress named Trunchbull. In one scene, schoolchildren in a spelling lesson chant letters with the word "Mrs." added to set the rhythm: "Mrs. D, Mrs. I, Mrs. FFI..." the Trunchbull bursts out, with an annoyed expression, "Why are all these women married?!" The "bull" in the name Trunchbull probably implies "bull dyke," a common derogatory term for lesbians.

** She's butch and unmarried so she must be a lesbian?
* Nina Sayers from ''BlackSwan'' seems to be a paranoid schizophrenic, and is as such psycho''tic'', but definitely not psycho''pathic''. She is clearly sexually attracted to Lily, although whether they actually ever have sex, or whether that was Nina's delusion, is difficult to know, as is whether she is violent toward anyone but herself, since the story is told from her perspective, making it impossible for the audience to know what is real and what are Nina's delusions. She is arguably, then, a notable deconstruction of this trope.

* The video for Amanda Palmer's "What's the Use in Won'drin?" seems to be setting up a story of a battered wife who's secretly in love with a female friend until the last thirty seconds or so, when it makes a [[http://www.youtube.com/watch?v=Lzek4sHZp-c&feature=channel distinct turn for the darker]].

->''"[[GirlsBravo Oh! You can pile-drive me next Miss Kirie!"]]''

For years, an unfortunate cocktail of censorship and bigotry rendered all lesbian characters on screen exclusively psychotic and villainous. HaysCode-era requirements that villainous and controversial characters be suitably punished meant that such characters [[BuryYourGays would almost inevitably be toast]] before the credits rolled - and this convention has persisted long after the demise of the Code itself.

* In ''IslandInTheSeaOfTime'' (1998) and its sequels ''Against the Tide of Years'' and ''On the Oceans of Eternity'' by S. M. Stirling, the chief henchwoman of the Big Bad, William Walker, is Alice Hong, a psychotically dangerous, sadistic, and bisexual nurse, nicknamed the Lady of Pain.

* Mona in the TV show ''Series/PrettyLittleLiars'' appears to be this, as she tries and fails to get rid of the other three liars so she can keep Hanna all to herself.

* This is the subtext to Ursula Imada's obsession with Sundra Peale in ''Nexus''. By the time of Ursula's [[spoiler:death]], it was only just barely subtext.

* DarkActionGirl [[VisualNovel/PhantomOfInferno Drei]] [[spoiler: rapes Mio]] with a gun.
** [[spoiler: Except Drei is not a lesbian; in fact, she treated Mio that way precisely because of Mio's relationship with Zwei, whom she is both in love and resents. This makes her more of a variation of a {{clingy jealous girl}}.]]

* In ''[[LightNovel/HaruhiSuzumiya Suzumiya Haruhi]]'' , fourth book, [[spoiler: the Asakura Ryoko of the AlternateUniverse]] ''seems'' to have somewhat Psycho Lesbian tendencies towards [[spoiler: Yuki. Given to that she's a normal human, yet ''still'' ends up stabbing Kyon to protect Yuki.]]

** And in the anime she seems even worse, sprinkling [[spoiler: Yuki]] with blood from her knife as she dances around in front of her...

* Miharu from ''[[LightNovel/BakaAndTestSummonTheBeasts Baka to Test to Shoukanjuu]]'' is crazily in love with Minami. Her solution to anyone who happens to get between her and Minami is to try to MurderTheHypotenuse.

* The first book in ''Literature/TheBeeboBrinkerChronicles'', ''Odd Girl Out'' (1957), stars Laura, who transitions from a self-loathing neurotic mess into a full-blown StalkerWithACrush who manipulates the pseudo-butch Beth into continuing a borderline [[TheMasochismTango Masochism Tango]] romance.

* Yuki, from "Webcomic/MenageA3". Not only does she have a brain disorder where she sees all male sex organs as "Naughty Tentacles", but she has repeatedly attacked said "Naughty Tentacles" ''with the intent of utterly destroying them''. She constantly turns the protagonist Gary's life into a living hell, forcing him to make out with his gay roommate and blackmailing him into helping her illustrate a manga. Yuki seems to be inching toward bi in recent strips, though, and has become ''somewhat'' friendlier.

* An episode of ''Series/LawAndOrderSVU'' had an "aggressive" (it's a subculture) lesbian accused of killing her girlfriend [[spoiler: it wasn't her, although she does have major anger problems.]]

* Semmerling from ''RidingBean''. Add to that the fact that she's a shameless pedophile and a ManipulativeBastard (maybe even a MagnificentBastard; she also displays elements of TheChessmaster and may be a sociopathic example of TheTrickster), and she's well on her way to fitting every negative stereotype of the screen lesbian.
* Shirai Kuroko from ''Anime/ToAruMajutsuNoIndex'' and ''Manga/ToAruKagakuNoRailgun''. However unlike most examples, Kuroko is a ''heroic'' use of this character type, who spends half her time stalking/fondling/trying to seduce her Mikoto-{{oneesama}} and the other half being a ReasonableAuthorityFigure [=/=] LittleMissBadass.

* Played for laughs with Anna from ''HeIsMyMaster''.
* DarkActionGirl Rimelda Jorg from ''{{Madlax}}''. Again, contrast with Madlax's other potential love interest, Vanessa.
* The results of ''{{Mai-HiME}}'''s WhamEpisode altered many characterizations, including the [[TheOjou kind and serene]] Shizuru who went a bit nuts near the end.
** ''{{Mai-Otome}}'' itself had one in Tomoe. While most of the Coral Otomes loved Shizuru and looked up to her as a heroic figure, Tomoe was actually ''[[StalkerWithACrush in love]]'' with her, and at one point attempted to kidnap and seduce her (in a decidedly [[{{Squick}} creepy fashion]]). This, coupled with her [[{{Yandere}} mean-spirited attitude]] toward some of the other characters had [[TheScrappy turned fan support against her]], though an attempt at a comedic makeover of her character in ''Zwei'' (similar to the one Shiho received in her transition from ''{{Mai-HiME}}'') tried to soften the blow somewhat.
* Ryofu Housen from ''{{Ikkitousen}}'' skirts this trope, though she can also be seen as a female DepravedBisexual. Slightly subverted, as her ''girlfriend'' Chinkyuu is the one who brings up her PetTheDog moments.

* Mylanda Arker Walder from ''BattleAthletes''.
* From ''GaoGaiGar'' FINAL we have one of the 11 Soul Masters, Pillnus. She takes a special...interest in [[ActionGirl Renais/Renee]], loving beating her in combat and putting her into...compromising positions. It's even implied she ''raped'' her.
* Ran Asuka from ''DevilmanLady'', who discovers and largely manipulates the lead character Jun Fudou, seems to be attracted to her, or at least her superpowers.
* Goldie Musou from ''GunsmithCats''.

* Mika from ''KyoshiroToTowaNoSora''.
* [[TheOphelia Ophelia]] from ''{{Claymore}}'' shows heavy signs of this thanks to her CombatSadomasochist tendencies. Roxanne even more so, with her habit of crushing on more powerful Claymores, [[IJustWantToBeYou copying their appearances]] and [[PowerCopying special techniques]], and then sadistically arranging their deaths.
* Nina Einstein of ''Anime/CodeGeass'', the cast's resident {{meganekko}} and [[TheScrappy racist]] who instantly falls head over heels in love with Eupehemia [[RescueRomance after her life is saved by the princess]], so much so that she [[CargoShip masturbates to pictures of Euphie using the edge of a table]]. After [[spoiler: Euphemia's death]], the girl '''[[{{Yandere}} really]]''' [[{{Yandere}} becomes unhinged]], enough to [[spoiler:try to destroy Tokyo with a [[FantasticNuke Sakuradite-bomb]] to kill Euphemias' killer, Zero and]] let [[EvilMentor Prince Schneizel]] [[MoreThanMindControl recruit and manipulate her]] into becoming a part of a research project that creates a nuclear weapon to wipe the Japanese race from existence. [[spoiler: She [[CharacterDevelopment gets over]] her madness ''and'' her racism, though. Not that the UnpleasableFanbase (or at least a part of it) acknowledges it. And not before having ''another'' FreakOut as she saw [[SphereOfDestruction what her bomb]] [[http://www.youtube.com/watch?v=7kOUZLaxzjE can do]]...]] Part of the reason is she makes some of the most disturbing [[http://i45.tinypic.com/21jng3s.jpg facial expressions ever...of all time]]
* B-Ko Daitokuji from ''ProjectAKo'' is a textbook example. While she is never explicitly called a lesbian, her affection for C-Ko clearly goes way beyond "pure affection," and sends her into increasingly over-the-top jealous rages against A-Ko, eventually involving military-grade weaponry and an invading alien armada (even though A-Ko and C-Ko's friendship is clearly only platonic, a point which is utterly lost on B-Ko.) For their part, A-Ko and C-Ko's relentless failure to acknowledge or even notice B-Ko's crush is probably a contributing factor in B-Ko's rage spiral. By the last two movies in the original setting, though, she could be called a "Psycho Bisexual", as she immediately "falls in love" with the same handsome biker that A-ko has her heart set on. That could just be her taking rivalry to the extreme, and/or reflect her intense envy of A-ko. Ironically, her dimensional counterpart in the "Vs." [=OAVs=] is nothing like her, and is even on fairly good terms with her dimension's version of A-ko.
* ''MagicKnightRayearth II'' has the delightfully bipolar (dementedly schizo might be a better descriptor) and certifiably psychotic Nova, whose switch every few moments from sweet and childish declarations of affection to a raving engine of powerful magical destruction can be a bit jarring. Although the circumstances of her consuming longing for Hikaru and the origin of both her and her madness are rather unique and in her own case most likely constitute use of this trope as a justified one.
* Asami Hoshino from ''MyselfYourself'', who was so in love with Shuri that she ended up causing the very object of her affection to leave. Though not before defending her from an AxCrazy old lady.

* Chikane Himemiya in the ''KannazukiNoMiko'' manga. [[spoiler: It later gets subverted when it's [[BatmanGambit revealed to be an act to fool the Orochi]] so she can destroy his support from within and manipulate Himeko to kill her, so they can activate the sacificial ritual to save the world [[RetGone without removing her beloved Himeko from existence]].]] Though it can be argued that [[spoiler: such a human being who is capable of performing such actions at all could not possibly be viewed as 100% "mentally healthy".....]] There's UnfortunateImplications about how she's so EasilyForgiven and ''idolized'' by fandom for such actions... likely just because she's a woman and GirlOnGirlIsHot.
* Subverted to a point in ''CynthiaTheMission''. BigBad Cybele is a cruel, evil sociopath who will has a tendency for cutesyness and being generally cheery and nice when she's not killing. She's also a lesbian, but there's nothing psycho about it.

* In ''SuzumiyaHaruhi'' , fourth book, [[spoiler: the Asakura Ryoko of the AlternateUniverse]] ''seems'' to have somewhat PsychoLesbian tendencies towards [[spoiler: Yuki. Given to that she's a normal human, yet ''still'' ends up stabbing Kyon to protect Yuki.]]

* [[spoiler: Yui]] from ''FushigiYuugi'' is speculated to be one of these for [[spoiler: Miaka]]. "I couldn't find a place between you and [[spoiler: Tamahome!]]", indeed!

* DarkActionGirl [[PhantomOfInferno Drei]] [[spoiler: rapes Mio]] with a gun.
* Liang Qi in ''{{Canaan}}'' is psychotically devoted to her adoptive "nee-sama" Alphard, and those who try to get in the way of the two of them being together tend to meet with her full AxCrazy wrath.

** There is also Hijiri the kids teacher who turns out to be working for the series BigBad and after fighting Kirie develops a similar attitude towards her. Before that it's mentioned that Hijiri had been obsessed with Miharu since childhood.

* Sousou from ''KoihimeMusou'' is a borderline case. Sure, she gets presented [[JerkassFacade relatively sympathetically]] as the series progresses, but not before [[BlackComedyRape forcing one of her subordinates into sex with her]] and trying to do the same with Kannu.
** Never mind that her subordinate is more than happy to comply with the "forcing...", though Kan'u only accepts a Sousou's proposal under duress.
* The second season of ''DarkerThanBlack'' has Mina Hazuki, [[FanNickname a.k.a.]] "Japanese Lesbian Catwoman". She's a Contractor who DoesNotLikeMen and [[NoSenseOfPersonalSpace shows absolutely no respect]] for the personal space of her female teammates, who she constantly hits on. The "psycho" comes from a combination of the usual Contractor LackOfEmpathy and a StalkerWithACrush attitude towards Kirihara.

* In ''LightNovel/{{Kampfer}}'', the BigBad, [[spoiler:Kaede, is a PsychoLesbian with the hots for the main character's [[AttractiveBentGender female form]].]]

* ''{{Mnemosyne}}'' has Sayara and Laura.
* Miharu from ''LightNovel/BakaToTestToShoukanjuu'' is crazily in love with Minami. Her solution to anyone who happens to get between her and Minami is to try to MurderTheHypotenuse.
* Kokoa from ''RosarioToVampire'' is utterly obsessed with the vampire side of her half-sister Moka.

* [[spoiler:Urushira]] from ''BondageFairies Extreme''. There's [[SplitPersonality more]] [[UnluckyChildhoodFriend to her]] than that, though.
* ''ZombieLoan'': The school nurse from the first two episodes, also Koyomi's "other" personality Yomi has a definite fondness for groping Michiru's breasts and attempting to molest her. Though the AssPull-ed its way out of this one by saying that [[spoiler:Yomi's spirit is actually that of a boy.]]
* ''PrettyFace'': Nozomi would go to great lengths to get Rando (as Yuna) into her bed.
* ''VenusVersusVirus'': Sumire, in Berserker mode! It's a little bit subtle as she is violent with the Viruses and more sexual (in a rape sort of way) with Lucia, as at one point she says they should "become one."

* [[spoiler: Bernkastel and Lambdadelta]] from ''VisualNovel/UminekoNoNakuKoroNi''. An odd example because they're a couple.
* ''WJuliet'': Nomura Tsugumi, Ito's senpai by one year, doesn't make it a secret that she wants "Ito-kun" for herself and can sometimes behave as a PsychoLesbian for comedy relief.
* Mao Nonosaka from ''MiraiNikki''. [[spoiler: She helps Hinata in her scheme to kill Akise, despite the fact that Hinata was only doing it to gain her father's approval. After Hinata apologizes for taking advantage of Mao's feelings, she actually tries to kill Yukiteru. Hinata herself doesn't really snap until Yuno stabs Mao.]]
* ''NagasareteAirantou'': Mikoto.
* Uruka from ''SteelAngelKurumi2'' for Nako. Uruka sees Kurumi as an obstacle to Nako and will try anything to remove Kurumi, even if it means asking her father to call upon the family's private army to take her down.

* Reimi from ''BambooBlade'' has [[StalkerWithACrush stalked]] Miyako from the shadows ever since the latter had [[CuteAndPsycho brutally]] rebuffed the advances of the former's crush in middle school (though the two attend different high schools). It soon emerges that, rather than wanting revenge on the boy's behalf, Reimi had become enamoured with how cool Miyako looked; she even has {{nosebleed}}s when she recalls the incident. However, she's not exactly the most subtle of stalkers; during a kendo sparring session between the two schools, Reimi walks right into the dojo, claiming to be in the photography club, and spends the whole time taking pictures of the weary Miyako.
* Rin "Clone" Yatagai towards Nao in episode 11 of OniiChanNoKotoNankaZenzenSukiJanainDakaraNe!! She ends up [[AccidentalKiss accidently]] [[ForcefulKiss kissing Iroha]] and falls in love with her instead much to Iroha's horror.
* ''KaguyaHime'': Although a bondage-wearer perv, Maggey is nice enough to be mostly harmless (beyond groping of strangers), and Chun-Lan is funny more than anything... but Mayu can get seriously scary.
* ''{{Hellsing}}'': In the first anime, a LesbianVampire character named Boobanshee/Bubbancy (actually a corruption of a Baobhan sith, pronounced roughly the same way in Japanese) tricks the entire Hellsing organization, save Seras and Alucard, into thinking that she is Integra's sister, Laura (a reference to ''Literature/{{Carmilla}}''). Later, she attempts to drink Integra's blood, and bites and licks her chest after partially undressing her, after which Integra realizes that she has no sister; shortly after Bubbancy is dispatched and Integra refers to her as Countess Karnstein (another ''Carmilla'' reference). She also licks Integra's blood from her hand after stabbing her.
* ''Manga/{{Saki}}'': Touka has a [[PsychoLesbian rather unhealthy obssession]] on [[strike:Nodoka]] Nodocchi. "I'm going to lick you all over and savor this delectable favor" anyone?
* ''{{Tactics}}'': The yuki-onna in the first episode (When she's possessed by an aradama, anyway.)
* ''LightNovel/ZeroNoTsukaima'': A LovePotion in season 3 episode 6 turns most of the girls into one of these. Also, Janette based on subtext. In the opening for the fourth season there's a part where Janette hugs a struggling Louise close and [[LecherousLicking licks her face]]. And in episode 2 of the fourth season Janette licks Louise on the face again and practically flirts with her calling her "cute and innocent" after slashing her with a poisoned knife.
* Chiffon Fairchild from {{Freezing}}, especially in the SpinOff Manga ''Freezing: First Chronicle''. To Wit, in the first half of the manga: she strips her roommate Ticy and [[SkinshipGrope playfully gropes her breasts]]. It's implied a little later that they went further. In the second half: [[spoiler: She [[CurbStompBattle slaughters]] 50 of her classmates ([[GoodThingYouCanHeal no actual ''deaths'']] but arms and legs fly left and right, nonetheless). The whole time she was muttering about wanting to 'destroy everything' and she is just a muscle reaction away from ''[[KilledOffForReal killing]]'' the 2nd ranked Pandora of her year before Ticy stops her with an [[IKnowYoureInThereSomewhereFight I Know You're In There Speech]]. All this with a [[PsychoticSmirk smile]] on her face.]] Oh and her nickname is [[NamesToRunAwayFromReallyFast The Monster of West Genetics]].
* 'Cockroach' Oki of Manga/{{Arachnid}} is an interesting case - her psychotic crush on the main character, Alice, actually makes her ''less'' dangerous, and soon results in a HeelFaceTurn. Subsequently, she's still a PsychoLesbian, but also one of Alice's only friends and most useful allies, thanks to her total lack of ulterior motives beyond getting into our heroine's pants.

* Roxy Richter from the ''ScottPilgrim books''. May well still be in love with Ramona and wants to cut Scott's head off. Although she's not noticeably more psycho than any of Ramona's other six evil exes, all of whom are men.

* The Daughters of the Amazon in ''YTheLastMan'' are frequently branded psycho lesbians by other women (they're certainly psycho, and have [[StrawFeminist little use for men]]). Subverted in that a) we never see any lesbian behavior among the Amazons and b) discreet lesbianism (especially with male impersonators) quickly becomes the norm in a world deprived of men. One of the few openly lesbian characters simply describes the Amazons as "nutters who cut off their norks".

* Subverted with [[VillainousHarlequin Harley Quinn]] and [[PlantPerson Poison Ivy]] in {{DC Comics}}. Their relationship with each other is probably the sanest either of them has.

* Eve Harrington from ''AllAboutEve'' (1950). Not outright stated, but quite explicit for the era, including a one-scene SpearCarrier whose presence is all but impossible to explain any other way.

* In the Spanish horror film ''TheBloodSpatteredBride'' (1972), a young bride, uneasy about sex with her husband, encounters LesbianVampire Literature/{{Carmilla}} and is seduced, and together they unleash murderous enmity toward men.

* ''TheMaids'' (1975) is all about this. Well, it has just three main characters: two are psycho lesbian sisters (the titular maids), and the third is their mistress who doesn't look very straight or very sane.

* SerialKiller Catherine in ''BlackWidow'' (1987). Though she seduces, marries and murders wealthy men (ostensibly for their money, but long past the point where she would already be rich) there's a definite lesbian subtext with the female Justice agent pursuing her.

* Hedy Carlson from ''SingleWhiteFemale'' (1992).
* Rebecca (played by Leighton Meester) from ''TheRoommate'', which is essentially a remake of ''Single White Female''.

* [[spoiler:Diane]] from ''MulhollandDrive'' (2001) is a lesbian, and definitely doesn't have both oars in the water. Interestingly, [[spoiler:she's the main character.]] [[MindScrew Assuming that part of the movie actually happened]].

* [[spoiler: Marie]] from ''HighTension'' (2003).

* Mary Whitaker from the ''Literature/LordPeterWimsey'' mystery ''Unnatural Death'' (1927); though Sayers also presents a lesbian couple in an earlier generation, Agatha Dawson and Clare Whitaker, as not psycho and as having a successful relationship.
* In Junichiro Tanizaki's novel ''{{Quicksand}}'' (1928), Sonoko Kakiuchi, a bored, wealthy housewife, is seduced by Mitsuko Tokumitsu, who proceeds to insinuate herself into Sonoko's life and utterly wreck it.

* In ''ThatHideousStrength'' (1945) by C. S. Lewis, the Big Bad is an organization that employs, among other baddies, a sadistically fascistic head of security named Miss Hardcastle, who is strongly implied to be lesbian.

* In ''Daemon in Lithuania'' (1973), some characters put on a play that contains half of all the old-fashioned clichés ever invented. Kinga is found to be pregnant, and: "Enter the Lady-in-Black. She nourished a tragic passion for Kinga, and heaped the most terrible reproaches on her head, striding up and down the stage and drawing on her long cigarette holder. Finally, she tossed it on to the ground, stamped on it, and flung herself on to her frivolous friend's couch, intending to strangle her..."

* One of the more uncomfortable subplots of Creator/TomClancy's ''[[Literature/JackRyan The Cardinal of the Kremlin]]'' (1988) features a American female rocket scientist who essentially hands her male co-worker over to [[MoscowCentre the KGB]] in order to (clumsily) attempt to [[ComfortingTheWidow seduce the guy's wife]].

* Lisbeth Salander is portrayed as this by the Conspiracy attempting to discredit her in ''[[TheMillenniumTrilogy The Girl Who Played With Fire]]'' (2006).

* An episode of ''LawAndOrderSVU'' had an "aggressive" (it's a subculture) lesbian accused of killing her girlfriend [[spoiler: it wasn't her, although she does have major anger problems.]]
* An episode of ''{{Torchwood}}'' had a [[NinjaPirateZombieRobot psycho lesbian from]] [[RecycledINSPACE space]].

* "[[ButchLesbian Daddy]]" from ''PrisonBreak: The Final Break''.
* Mickie James from Wrestling/{{WWE}} started out as Trish Stratus' psychotic lesbian stalker.

* Several in the first two seasons of ''{{NCIS}}''. Since the second season ended, their problem with Psycho Lesbians seems to have disappeared:

* ''LegendOfTheSeeker'' has one in [[spoiler: Dahlia, Cara's ex-girlfriend who betrays her, kidnaps her and tortures her into becoming one of the screwed up family again. When she kisses Cara (who is chained up, bruised and bleeding) and Cara head butts her, she does not respond to the rejection well, though fortunately all we get is her statement/threat that her previous torturer was 'being too gentle.']]

* Mona in the TV show PrettyLittleLiars appears to be this, as she tries and fails to get rid of the other three liars so she can keep Hanna all to herself.
* Several characters of ''Cutie Honey The Live''. The title character, Honey, is lusted after by another female main character, Yuki. Yuki gets extremely jealous and posessive although they never develop a romance, her insanity builds up to the point where she becomes the main villain. Additionally, another main character, Miki, initially appears to be somewhat insane (introduced in a prison, then slaughters a bunch of men attacking the prisoners; proceding to become a hero until her death, only to be brought back to life, only to be merged (in the midst of a lot of lesbian subtext) with Honey to help her defeat the Psycho Lesbian villain Yuki. That's not all, however; Mayumi, a sadist teacher who likes to perform an ambiguous lesbian sex act involving raw eggs on her students, develops a passionate attraction towards Miki, whilst fighting the heroes throughout the series. In the end, in Miki's last moments, she finally shares a kiss with her.
* ''{{Smallville}}'': Tina Greer, Lana's only lesbian StalkerWithACrush of the Week.

* The murderer in one of the season 5 ''{{Psych}}'' episodes, who is also an aversion of NobodyOver50IsGay.
* The ITV ''MissMarple'' adaptation of ''The Body in the Library'' actually ''changed the identity of the killer'' from Christie's original plot in order to cater to this trope.

* On ''{{iCarly}}'', Missy is believed to be this and some people also view Sam as one as well, and their episode together made it look like two PsychoLesbian's fighting for the love of Carly.

* One possible interpretation of {{PJ Harvey}}'s "Catherine", where a woman is singing about her envy and anger towards the titular character, and [[MurderTheHypotenuse plans to murder her current lover.]]
* The unnamed narrator in SoundHorizon's "Baroque" seems to have been a fairly nice girl (if shy and socially awkward) [[LoveMakesYouEvil until she fell in love with another girl]] and proceeded to [[{{Yandere}} push said girl down a flight of stairs for rejecting her]].

* The antagonist [[spoiler: Wendy]] from ''RuleOfRose''. It turns out that she was the [[{{Chessmaster}} mastermind]] behind all the tormenting and torture of Jennifer, including the execution of [[spoiler: Brown, the loyal and loveable dog that Jennifer loved]]. All of this was apparently [[spoiler: "punishment" for Jennifer "falling in love with Brown".]] Unfortunately, the last one was [[BreakTheCutie what brought Jennifer over the edge]]. However, it's hard to call foul when [[DysfunctionJunction everyone in that orphanage was nuts]].
* Amongst the AxCrazy bosses of ''DeadRising'', Jo Slade stands out. A sadistic police officer who brutalizes young women, she was one of the creepiest enemies in the game.
* [[GiantSpider Hirasaka]] Hatsune from ''VisualNovel/AtlachNacha'' absorbs energy by having sexual intercourse with people or eating them. She prefers females for sex and males for eating. If you piss her off, she ''will'' tear you apart before devouring you... all with a smile, too.
* Claudia Wolf of ''SilentHill3'', [[EpilepticTrees possibly]]. She seems to be obsessed with Heather, or rather with Alessa, in more ways than one.

* Inverted in ''ADanceWithRogues'', in which the lesbian characters tend to be nicer.

* You can play as this in ''VampireTheMasqueradeBloodlines'', if you play as a [[LesbianVampire female character]] with low [[KarmaMeter humanity]]. Incidentally, if you play as a female Malkavian, you can be a ''psychotic'' lesbian: all Malkavians are incurably insane; psychotic is not the same thing as psychopathic, of course, and it's entirely possibly to play as a very humane and decent Malkavian. You'll still be psychotic, though. Jeanette Voerman is also a Malkavian, and is as such psychotic, and would appear to be bi-, or perhaps [[AnythingThatMoves omni-sexual]].

* ''UminekoNoNakuKoroNi'' offers a rare ''mutual'' example with Lambdadelta and Bernkastel. At first it seems like it's Lamda's one-sided MadLove that makes her want to keep Bern all for herself. In Episode 5 though, it turns out they have a genuine love for each other. Very violent and twisted, but genuine nontheless.

* Yukari and Yuyuko from ''VideoGame/{{Touhou}}'' are like this in the 18+ version of the ''{{IOSYS}}'' fan video ''Border Of Extacy''. For general safe for work principles and sanity, a link shall not be provided. (A search on Website/YouTube will not reveal this video but will reveal the other version of the video)

* In Chloe's web comic ''GoGetARoomie'', "Roomie" of the title appears to manifest this trope: technically homeless, but playing on her charm and good looks to obtain rent-free stays with a string of lovers, taking them for granted for everything until she gets bored and moves on, generally wearing stolen clothes and with whatever money she can scoop up on the way out. It is only way into the series that it is revealed she does have feelings for others and a conscience, but the Roomie of the early strips is a heartbreaking conscienceless psychopath.

* In ''YuMeDream'' Sadako is a pretty perfect example. That being said, [[CastFullOfGay other characters]] provide more positive depictions of homosexuality and bisexuality.

* One of [[ManicPixieDreamGirl Vanessa's]] exes in ''SomethingPositive'', whom she left for casting aspersions on her bisexuality once too often, apparently still calls her, begging to get back together while calling her "whore."
* Yuki, from "MenageA3". Not only does she have a brain disorder where she sees all male sex organs as "Naughty Tentacles", but she has repeatedly attacked said "Naughty Tentacles" ''with the intent of utterly destroying them''. She constantly turns the protagonist Gary's life into a living hell, forcing him to make out with his gay roommate and blackmailing him into helping her illustrate a manga. Yuki seems to be inching toward bi in recent strips, though, and has become ''somewhat'' friendlier.
* Chi, Aku's daughter in ''GrimTalesFromDownBelow'', [[StakerWithACrush specifically towards Mimi]].

* DiamandaHagan. PlayedForLaughs.
* Lyn "Laeil" Burbank of ''SurvivalOfTheFittest'''s third version. After confessing her love to a female friend, she gets bullied by her classmates for being a "dyke". Once she gets on the island, she kills her cousin (who was one of her major bullies) by [[GroinAttack stabbing him in the groin repeatedly]]. Afterwards, she decides that she was going to die anyways, and that she was going to [[RoaringRampageOfRevenge get revenge on everyone who ever bullied her]].
** Reiko Ishida in version 4 likely qualifies as well, rather quickly abandoning any pretense of possessing a conscience. Her sexuality and sociopathy seem largely unrelated, however. In fact, in a way it's subverted; she seems to genuinely care for her girlfriend Sarah Xu, and after a bit of CharacterDevelopment starts to be concerned about what she thinks of her actions.

* Liang Qi in ''{{Canaan}}'' is psychotically devoted to her "sister" Alphard, and those who try to get in the way of the two of them being together tend to meet with her full AxCrazy wrath.

* Liang Qi in ''{{Canaan}}''.

* On ''iCarly'', Missy is believed to be this and some people also view Sam as one as well.
