->''"I never liked that people took her for bisexual because she's an evil character. There are so few gay characters on TV, and we really don't need an evil one."''
-->-- '''Nana Visitor''' (on her character Kira's {{mirror universe}} counterpart), ''Series/StarTrekDeepSpaceNine''

For years, an unfortunate cocktail of censorship and bigotry rendered all lesbian characters on screen exclusively psychotic and villainous. UsefulNotes/TheHaysCode-era requirements that "deviant" characters (and that included all gay characters of either gender) must not be made sympathetic or rewarded meant that such characters [[BuryYourGays would almost inevitably be toast]] before the final credits rolled - and this convention has persisted long after the demise of the Code itself.

This trope carries uncomfortable subtext: go straight or go crazy. Or ''at least'' [[BrokenAesop have the decency of being bisexual]] so you can be [[GirlOnGirlIsHot of proper use for men.]] Add to that the way that real-life lesbians are often seen as irrational or man-hating by straight people of both genders as well as gay men, and it begins to look like a DiscreditedTrope.

The Psycho Lesbian will often be a villainess for a HideYourLesbians couple; two women who care for each other but don't actually say it out loud.

See DepravedHomosexual for the male equivalent. See HeteronormativeCrusader for when another character considers a lesbian to be psycho simply for being lesbian. See also LoveMakesYouEvil, LoveMakesYouCrazy, and {{Yandere}} for more general tropes that are closely related. See StrawFeminist if she's simply a lesbian who ''[[DoesNotLikeMen hates]]'' men.



[[folder:Anime & Manga]]
* Nami in ''Aki Sora''. She starts out with a MatchmakerCrush involving her best friend Kana and her brother Sora, but after the date she set them up on went far beyond her expectations, she [[spoiler:confronts Sora that evening, shoves him down, stops just shy of cutting off his penis with some scissors ("Hey... can I have this?"), rapes him while fantasizing that she has a penis and is having sex with Kana, and threatens afterward to cut his penis off for real if he ever tells anyone]].
* '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 Psycho Lesbian, 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.
* Miharu from ''LightNovel/BakaAndTestSummonTheBeasts'' is crazily in love with Minami. Her solution to anyone who happens to get between her and Minami is to try to MurderTheHypotenuse.
* Double subverted with Suruga from ''LightNovel/{{Bakemonogatari}}'' who is dangerously in love with Hitagi. She is actually a perfectly pleasant person, even to Koyomi, her crush's boyfriend. But she unconsciously wishes that Koyomi would disappear, and when the sun goes down her demonic hand takes control over her and tries to grant her wish, which means trying to beat Koyomi to death twice. There's also the fact that she starts stalking Koyomi after he hooks up with Hitagi.
* Reimi from ''Manga/BambooBlade'' has {{stalk|erWithACrush}}ed 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.
* Kagari from ''Anime/BlackRockShooter''. [[spoiler:A pure example for the first two episodes of the series, with her possessive crush on Yomi Takanashi.]]
* Played for laughs with Chizuru Honshou of ''Manga/{{Bleach}}''. Two words: [[Funny/{{Bleach}} "Karakura Raizer!"]] She is very disturbed in many ways which is best depicted when she asks what a little girl's cup size is.
* [[spoiler:Urushira]] from ''Bondage Fairies Extreme''. There's [[SplitPersonality more]] [[UnluckyChildhoodFriend to her]] than that, though.
* Liang Qi in ''Anime/{{Canaan}}'' is [[{{Yandere}} 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.
* Shirai Kuroko from ''LightNovel/ACertainMagicalIndex'' and ''Manga/ACertainScientificRailgun''. 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.
* [[TheOphelia Ophelia]] from ''Manga/{{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 Euphemia's 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]]
* ''Anime/CrossAnge'': Zola literally had her own harem and she approaches Ange very forcibly, despite Ange making it perfectly clear that she doesn't want it.
* Subverted to a point in ''Manga/CynthiaTheMission''. BigBad Cybele is a cruel, evil sociopath who 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.
** Also a subversion from the same manga, Takaya Kanae is a sweet, kind, gentle schoolgirl who has kissed more then a few girls in her day. Not psycho at all by any means... until you get to her alternate personality, Shii, who is a psychotic, evil man who will do anything to protect the innocent Takaya, while leaving her mostly unaware of his protection.
* The second season of ''Anime/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.
** Actually, even though she's extremely forward at first, she takes being rejected by Kirihara [[TheStoic fairly]] [[EmotionlessGirl well]], all things considered. [[spoiler: It's after Youko is brutally murdered, seemingly by Hei, that [[TranquilFury things]] [[ItsPersonal get]] [[LetsGetDangerous dangerous]].]]
* Ran Asuka from ''Manga/DevilmanLady'', who discovers and largely manipulates the lead character Jun Fudou, seems to be attracted to her, or at least her superpowers.
* Fatora and Alielle of the original OAV version of ''Anime/ElHazardTheMagnificentWorld'' are extremely promiscuous lesbians who are constantly attempting to seduce, or outright molest, other women they find attractive, and will not take no for an answer, even if the objects of their "affection" protest about being heterosexual. Fatora is particularly psychotic about it, especially in the sequel series ''El Hazard 2'', where she outright tries to trick Shayla-Shayla into having sex with her by playing on the fact that [[DudeLooksLikeALady Makoto, the boy Shayla-Shayla likes, resembles her so strongly]].
* ''LightNovel/TheFamiliarOfZero'': 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 ''Manga/{{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 Somewhere" Speech]]. All this with a [[PsychoticSmirk smile]] on her face.]] Oh and her nickname is [[NamesToRunAwayFromReallyFast The Monster of West Genetics]].
* [[spoiler:Yui]] from ''Manga/FushigiYuugi'' is speculated to be one of these for [[spoiler: Miaka]]. "I couldn't find a place between you and [[spoiler: Tamahome!]]", indeed!
* Mao Nonosaka from ''Manga/FutureDiary''. [[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.]]
* ''Anime/GaikingLegendOfDaikuMaryu'' has [[spoiler: Proist, the BigBad, and the only character in the show who could probably be called more evil than simply self-serving or misguided]]. She's only shown to have affection for her father and for Vestaanu. She is also completely unpredictable, casually [[AMillionIsAStatistic executing thousands who don't live up to her standards]], and can and will [[HairTriggerTemper fly into a rage at the slightest provocation]].
* Rio in ''Gamerz Heaven'' ...she doesn't seem to have any sanity whatsoever when it comes to Kyouko.
* From ''Anime/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.
* ''Manga/GirlsBravo'':
** Kosame's lust for Kirie is played up [[GirlOnGirlIsHot for fanservice]] and [[BlackComedyRape as comedy]]. Particularly during the [[CatFight "Girls Fight!"]] [[TournamentArc competition]] and a later episode where she chases Kiriei around the house, while calling her [[BigSisterAttraction "big sister".]]
** 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.
* Goldie Musou from ''Manga/GunsmithCats''. She's a drug-dealing Mafia boss whose AmazonChaser fetishes leads her attempting to abduct and brainwash Rally Vincent, and then succeeding in doing so to Misty, with heavy hints that she raped Misty after brainwashing her into loving her. [[spoiler: What irritates many fans is that Goldie ends up as a KarmaHoudini; not only does VetinariJobSecurity ensure she remains the local Mafia boss, but she also gets to ''keep'' an arguably still-brainwashed Misty as her lover in her own "happily ever after".]]
* ''LightNovel/HaiyoreNyarkoSan'' has Cuko, who has an unrequited crush on Nyarko and has repeatedly expressed her desire to get married and [[HomosexualReproduction have kids]] -- not to mention beginning the series wanting to [[MurderTheHypotenuse kill Nyarko's love interest Mahiro]] ([[BiTheWay at least until she warms up to him]]). Of course, the "Psycho" part comes almost entirely from her being Cthuguha the Living Flame, who was depicted in the Franchise/CthulhuMythos as being legitimately insane.
* In ''The Disappearance of LightNovel/HaruhiSuzumiya'', [[spoiler: the Ryoko Asakura of the AlternateUniverse]] ''seems'' to have somewhat Psycho Lesbian tendencies towards [[spoiler: Yuki Nagato. Given to that she's a normal human, yet ''still'' ends up stabbing Kyon to protect Yuki.]]
** She even waits for her at the school at 4:00 AM!
** And in the movie she seems even worse, sprinkling [[spoiler: Yuki]] with blood from her knife as she dances around in front of her...
* The Season 2 premiere episode of ''Anime/HellGirl'' has a cute high school girl being harassed by a unknown person. [[spoiler: By the end of the episode, it's revealed that the seemingly nice school nurse, is sadistic bully with a perverted obsession with the high school girl. She threatens to pour acid of her face if she doesn't give into her. The girl is able to sent the nurse to hell.]]
* ''Manga/{{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/IkkiTousen'':
** Ryofu Housen 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.
** Kan'u Unchou ''almost'' ended up as one of these, what with [[BodyguardCrush her devotion to Ryuubi]] being [[{{Flanderization}} taken to extremes]] in the third series. She did not, fortunately, as it only happened because she was kind of BrainwashedAndCrazy due to an amulet that goes to extract her deepest desire [[CannotSpitItOut that thus far she managed to hide]]. After the hijinx, her relationship returned normal [[spoiler: and got [[RelationshipUpgrade upgraded]] at the end of the series]].
* ''Manga/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.
* In ''LightNovel/{{Kampfer}}'', the BigBad, [[spoiler:Kaede, is a Psycho Lesbian with the hots for the main character's [[AttractiveBentGender female form]].]]
** [[spoiler: For bonus points]], while the rest of the female cast [[GirlOnGirlIsHot show some bisexual tendencies]] [[DepravedBisexual and have their crazy sides]], [[spoiler:Kaede]] herself - the only 100% gay character - is portrayed as the worst.]]
* Chikane Himemiya in the ''Manga/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]].]]
* Nui Harime from ''Anime/KillLaKill'' shows interest in both Satsuki and Ryuko. [[spoiler: Justified as the main authority figure/surrogate mother Ragyo liked to do... [[ParentalIncest things to her]] so she may have gotten both the psycho and the lesbian parts from her]]
* Kasumi Kisaragi, the vice-president in the 2006 version of ''Kujibiki Unbalance'', especially in the manga adaptation, where she tries to kill Chihiro when a love potion causes her to be attracted to him.
* In ''LightNovel/LoveChunibyoAndOtherDelusions'' episode 8 of second season ''Ren'', a girl pretended to be Mori Summer so that she can molest Dekomori.
* [[DarkActionGirl Rimelda Jorg]] from ''Anime/{{Madlax}}''. Again, contrast with Madlax's other potential love interest, Vanessa.
* ''Manga/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.
* From ''Manga/MahouSenseiNegima'', we have secondary villain Tsukuyomi. She starts as a mere PunchClockVillain with shades of PsychopathicWomanchild and a crush on her [[SempaiKohai ex-sempai]] Setsuna Sakurazaki, but as time passes, she becomes [[StalkerWithACrush really, *really*, creepily obsessed with Setsuna]]. And also seems to derive sexual pleasure from murder. And it gets more explicit. She's also probably the only villain in the series who's evil with no AntiVillain tendencies or FreudianExcuse for her actions, which just makes her even creepier than most other bad guys.
* ''Franchise/MaiHime'':
** The results of ''Anime/MaiHime'''s WhamEpisode altered many characterizations, including the [[TheOjou kind and serene]] Shizuru who went a bit nuts near the end.
** ''Anime/MaiOtome'' 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 ''Anime/MaiHime'') tried to soften the blow somewhat.
* In ''Anime/MawaruPenguindrum'' it's implied that Tsubasa stabbed Tabuki out of jealousy once Yuri broke off their affair.
%%* ''Anime/{{Mnemosyne}}'' has Sayara and Laura.
* Kuroko Koumori, the main character of ''Manga/{{Murcielago}}''. Interestingly, her being psycho is the main focus, while her being a lesbian is treated as a side note.
* Asami Hoshino from ''Anime/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.
%%* ''Manga/NagasareteAirantou'': Mikoto.
* Chloe of ''Anime/{{Noir}}'' fits this, but only in her final appearance. She met the lesbian criteria the entire time, but she doesn't turn psycho until after Kirika rejects (or more accurately, fails to even notice) her advances, and then acts to protect Mireille from her, causing her to snap.
* Rin "Clone" Yatagai towards Nao in episode 11 of ''Manga/OniichanNoKotoNankaZenzenSukiJaNaiNDakaraNe'' She ends up [[AccidentalKiss accidently]] [[ForcefulKiss kissing Iroha]] and falls in love with her instead much to Iroha's horror.
* ''Manga/PrettyFace'': Nozomi would go to great lengths to get Rando (as Yuna) into her bed.
* [[spoiler:Homura Akemi]] became this at the end of ''Anime/PuellaMagiMadokaMagicaTheMovieRebellion''. [[AntiVillain Maybe]]. It depends on which side of the BrokenBase you are.
* Echidna from ''Anime/QueensBlade'' uses this as part of her mercenary gig, though she is less of the former and more of the later.
** The same series also gives us the sociopathically self-centered Elina Vance, who in the first episode goes off on a rant about how she'll torture the man who ends up marrying the woman she loves. Oh, and did we mention the woman she loves is [[BrotherSisterIncest her elder sister]]?
** Zigzagged with Menace. Yeah, she's a lesbian and a huge pervert, so much so that she [[BadBoss basically caused the downfall of her country because she couldn't be bothered to drag herself away from her huge harem of female slaves]]. And yes, she's at least a nominal villain who is working for the series' BigBad so she can rebuild her kingdom. But, she's also quite rational and controlled, if obsessive, and certainly not as outright crazy as is normal for this trope.
* A one shot yuri manga by the name of ''Rapunzel'' turns it UpToEleven with not one, but two of them. [[spoiler:One cuts off the hair of the other in a fit of [[{{Yandere}} jealous rage]], and then the one who had her hair cut [[{{Squick}} cuts out]] [[EyeScream the eyes]] of the other [[SerialEscalation as revenge]]. To top it off, the girl who did the cutting of the hair ''let her eyes be cut out'' '''while smiling'''. At the very end, they're both shown smiling and holding each others hands in the conclusion. LoveMakesYouCrazy indeed.]]
* Semmerling from ''Anime/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.
* ''Manga/RosarioToVampire'':
** Kokoa is utterly obsessed with the vampire side of her half-sister Moka.
** Akuha of manga season II is revealed to be one of these for [[EvenTheGirlsWantHer Moka]].
* ''Manga/{{Saki}}'': Touka has a rather unhealthy obssession on [[strike:Nodoka]] Nodocchi. "I'm going to lick you all over and savor this delectable favor" anyone?
* Uruka from ''Anime/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.
* ''Manga/{{Tactics}}'': The yuki-onna in the first episode (When she's possessed by an aradama, anyway.)
* ''Manga/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."
** In the anime version, Lucia appears to be this when she [[spoiler:''stakes'' Sumire's boyfriend in front of her.]] Of course, she thought he was dangerous but it's still a bit out there.
* Shiori in ''Anime/{{Witchblade}}'', although her PhlebotinumBreakdown may have helped. Then again, she was a bit messed up to begin with.
* ''Manga/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 Psycho Lesbian for comedy relief.
* ''Anime/YuriKumaArashi'':
** Mitsuko turns out to be a lot more predatory than she first appeared.
** Yurika ate Reia out of possessiveness, jealousy, misplaced anger and heartbreak. Kureha being the focus and recipients of Reia's love since her birth, combined with her StrongFamilyResemblance to Reia, also drove Yurika half-mad with lust when she attempted to eat her.
* ''Manga/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.]]

[[folder:Comic Books]]
* The [[GenderFlip Lady Lemongrabs]], from the ''WesternAnimation/AdventureTime'' Fionna and Cake comic book series. The "lesbian" part seems to be incidental, as they're the genderswapped versions of characters who were VERY AmbiguouslyGay and happened to also be clinically insane.
* The version of Wonder Woman that appears in Creator/FrankMiller's ''ComicBook/AllStarBatmanAndRobinTheBoyWonder'' is at least hinted to be this. Although, considering the version of [[JerkAss Batman]] that does the hinting, it could just be him being his usual [[BlatantLies charming]] self.
* Inverted in the case of Victoria Hand in ''ComicBook/DarkReign''. She is a lesbian (or perhaps bisexual) and easily the most sane of all of Norman Osborn's [[LegionOfDoom subordinates]] (Osborn himself included), but that might not be saying too much when everyone else is a PsychoForHire at best and EldritchAbomination at worse.
* Inverted with [[VillainousHarlequin Harley Quinn]] and [[PlantPerson Poison Ivy]] in [[Franchise/TheDCU DC Comics]]. Their relationship with each other is probably the sanest either of them has.
* Not the point of the alt comic ''Hothead Paisan: Homicidal Lesbian Terrorist''; although it may have addressed this trope at times, it's more a spoof of StrawFeminist fears.
* Nearly every major lesbian/bisexual female character in Creator/MarvelComics continuity has been assigned some degree of mental instability. The bisexual [[ComicBook/SpiderWoman Skein]], for instance, married an older man and then killed him for his money; [[ComicBook/{{Thunderbolts}} Man-Killer/Amazon]] used to be a man-hating militant feminist; [[ComicBook/TheOrder Mulholland Black]] went so crazy [[spoiler:that her own teammates put her down]], [[ComicBook/ThePunisher Molly von Richthofen]] turned out to violently assault ''anyone'' who even looked at her openly bisexual partner, etc. Even the ones without criminal pasts have been portrayed as less than fully sane; The ''[[ComicBook/TheLoners Loners]]'' miniseries portrayed bisexual [[ComicBook/PowerPack Lightspeed]] as being the superhero equivalent of a FormerChildStar, with all the attendant mental baggage, while the lesbian [[ComicBook/{{Runaways}} Karolina Dean]] is bipolar, according to the Marvel Handbooks.
* 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. Averted with Jil, who is a lesbian but not at all psycho, and Sundra, who is clearly bi and also not at all psycho.
* ComicBook/{{Purgatori}}, the [[LesbianVampire lesbian vampire demon]] originally created by Brian Pulido as an antagonist for his main {{stripperiffic}} heroine, ComicBook/LadyDeath. She may actually be a DepravedBisexual, having once been Satan's concubine, but all of the (semi-)consensual relationships we've seen have had her with women.
* The Daughters of the Amazon in ''ComicBook/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".
** They're likely "political lesbians" - heterosexual radical feminists who "became lesbians" for ideological reasons. Many real lesbians don't like them because their stance reinforces the fallacy pushed by homophobes that homosexuality is a choice. Another complaint from quite a few real lesbians who have been in relationships with political lesbians are that political lesbians are often [[LieBackAndThinkOfEngland unenthusiastic about gay sex]], which the comic is probably pointing out.

[[folder:Fan Works]]
* Commander Sullamander from ''FanFic/ABriefHistoryOfEquestria''; the lover of the previous commander (supposedly since she was a foal), Sullamander ruled the Celestine Junta with an iron hoof, executing anyone that spoke out against her and once attempting to ban or severely limit heterosexual unions. At the end of her life, she had gone full crazy and demanded that her soldiers worship her as a god, even as her enemies were already breaking through her forces and on their way to kill her. [[SuspiciouslySpecificDenial Of course, her lesbian tendencies were played up in sources by propaganda or less-learned scholars whose minds were too far in the gutter.]]
* Pretty much all of the [[StrawFeminist feminists]] in the ''Fanfic/MRATrilogy'', with special notes going to [[Disney/{{Frozen}} Elsa]] (who is in an [[VillainousIncest incestuous]] relationship with her sister Anna, and is reffered to as "queen of feminists and lesbo dykes") and [[Franchise/MassEffect Benezia]], the whole purpose of the fanfic in which she debuts being the [[MarySue protagonist]] trying to seduce her in order to distract her. Ironically, the protagonist is arguably also this, since she has sex with other women (albeit "for the benefit of men") and has severe VillainProtagonist tendencies.
* ''Fanfic/OutOfTheCornerOfTheEye'' has Asenath Waite, a homicidal sociopath in service of the [[Literature/CthulhuMythos Outer Gods]], who just so happens to also be a lesbian on top of all that.

[[folder:Films -- Live-Action]]
* The titular [[LesbianVampire lesbian vampires]] from ''Film/LesbianVampireKillers''. The pschotic-ness seems to be due to the vampire part of being [[LesbianVampire lesbian vampires]], [[spoiler: since the women who are saved at the end of the movie seem to be quite agreeable lesbians]].
* Eve Harrington from ''Film/AllAboutEve'' is often imagined to be one by {{Fanon}} - due to her obsession with becoming like Margo Channing. Regardless she does try to seduce two men in the movie.
* Roxy, Catherine Trammell's girlfriend in ''Film/BasicInstinct''. Paired with ClingyJealousGirl, as she tries to kill Nick, Catherine's other lover, when he refuses to leave Catherine alone as Roxy has ordered him to, and is briefly viewed as one of the suspects in killing the man murdered in the film's opening.
* Nina Sayers from ''Film/BlackSwan'' (2010) 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 [[UnreliableNarrator 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.
* In the Spanish horror film ''The Blood Spattered Bride'' (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.
* Eunice from ''Butterfly Kiss'' (1996) is very much this trope; the only twist is that the girl she's obsessed with reciprocates her feelings, and they turn into an OutlawCouple that wreak havoc in their wake.
* Harris from ''Camp Blood'' (2000) went insane and became a serial killer after catching her girlfriend cheating on her with a man.
* Amy, Heather Graham's character in ''Film/{{Compulsion}}'', is implied to be this throughout most of the film, as it obvious as the story is told through flashbacks that she was obsessed with her neighbor Saffron (Carrie-Anne Moss) and is clearly lying to Det. Reynolds (Joe Mantegna) about how well she knew Saffron. In the end, it is revealed that [[spoiler:that Amy and Saffron did have sex, after which [[ImAHumanitarian Amy killed, butchered, cooked, and ate]] Saffron, but that it was all consensual.]] That may mean that they were both examples of this trope.
* Miss G from ''Film/{{Cracks}}'' (2009) definitely fits this trope. From the start of the film is clear somethings not quite right with her and over the the course of the film she shows many signs of having some sort of mental disorder. Later in the film she becomes obsessed with a female student to the point of actually raping her.
* Parodied in ''Film/{{DEBS}}'' (2003). The villainess Lucy Diamond is more than willing to sink the entire continent of Australia in frustration over not being able to form an emotionally satisfying lesbian relationship. Fortunately she is redeemed by the love of an incredibly hot secret agent in a [[SchoolgirlLesbians plaid skirt]]. Then there was Lucy's blind date Ninotchka, who was clearly not all there and completely lost it when Lucy tried to back out of their date.
* There's a downright aggressive and vicious woman at the stereotypical [[WhereEverybodyKnowsYourFlame lesbian bar]] in ''Film/FoxyBrown'' (1974).
* [[spoiler: Marie]] from ''Film/HighTension'' (2003).
* The animal liberation group/diamond thieves from ''Film/JayAndSilentBobStrikeBack'' (2001), according to a deleted scene and Kevin Smith.
* 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. More to the point, [[AuthorAppeal she and Needy do kiss at one point]].
* In ''Franchise/JurassicPark'', the raptors are all females (and also "homeothermic", which is possibly innuendo). The Big One is an indiscriminate killer, but she still sacrifices her life to avenge the death of her mate.
* ''Kate's Addiction'' (1999) follows Kate's obsessive pursuit of former friend Sara up to and including killing anyone who gets in her way.
* Sister George from ''The Killing of Sister George'' (1968) is pretty unstable, and very possessive of her lover. There's also her predatory boss Mercy Croft.
* In ''Lost and Delirious'' (2001), the main character learns that her boarding school roommates are in love. One girl's family pitches a fit, and she goes to sleep with the first guy she sees, and the other girl goes completely insane, chasing eagles in the woods and [[spoiler: she commits suicide at the end. It's even worse because the older teacher tries to save her by sharing her own forbidden love.]]\\\
Paulie's much less palatable in the book: She not only [[spoiler:dresses up as a guy, but deceives the entire school population into thinking she has a brother]], but she worships King Kong and she strings (the much ''less'' naive) Mouse along much further. Her own sexuality is never mentioned, although there's a brief scene with Tori, who professes a crush on "Lewis". The older teacher is still in a forbidden romance (here explicitly stated when Paulie and Mouse find letters from the teachers), but this is better justified by deliberate ValuesDissonance (the book's set in the 50's).
* ''Film/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.
* ''Make a Wish'' (2002), an alternate title for which is even ''Lesbian Psycho''. A group of lesbians go camping in the woods. Is the killer one of the male red herrings? [[spoiler: Nope]]
* Syl and Madie from ''Film/{{Maskhead}}'' (2009) are a sick lesbian couple who make fetish porn that always ends with the participants being slaughtered by their pet killer, the eponymous Maskhead.
* [[spoiler:Diane]] from ''Film/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]].
** It's worth noting though that she comes off as more of the genuinely unbalanced sort, than the more AxeCrazy psychos that can be found on this page.
* Ruby from ''Film/TheNeonDemon'' (2016) fits this to a T, obsessing over the female lead, leading to an AttemptedRape, as well as having an ILoveTheDead moment with a female cadaver at her job in the morgue.
* Barbara Covett of ''Film/NotesOnAScandal''. Although the relationships we hear of and see her in (Jennifer and Sheba, respectively) are platonic, it's obvious she wants more. She is also a ClingyJealousGirl, having sent Jennifer's fiance a funeral wreath, and refusing to understand why Sheba's family takes priority over her.
* The evil Queen Gedren from ''Film/RedSonja'' (1985) seemed visibly attracted to the titular character, before said character disfigured her.
* The sadistic Nazi Ingrid in Roberto Rossellini's seminal classic ''Rome, Open City'' (1945). Ingrid plies her targets with luxuries like narcotics and fine clothes in order to gather information on the Italian resistance in Rome; eventually disposing of them when they outlive their usefulness. The young woman she seduces doesn't come off too well either, but she's desperate, bitter, and impoverished in war-torn Rome and is somewhat easier to sympathize with.
* Rebecca (played by Leighton Meester) from ''Film/TheRoommate'', which is essentially a remake of ''Single White Female''.
%%* Hedy Carlson from ''Film/SingleWhiteFemale'' (1992).
* In ''Film/WhatsTheMatterWithHelen'' the titular Helen is meant to be a repressed lesbian going slowly madder over the course of the film. A scene was filmed where Helen kisses Adelle on the lips after [[spoiler: they've covered up a murder]] but the censors ordered it removed. Nonetheless the subtext is definitely there.
%%* Andrea Glassen from ''Windows'' (1980).
* As the HalfwayPlotSwitch reveals in ''Film/LakeBodom'', all the deaths in the movie are caused by [[spoiler:Nora's unrequited crush on Ida-Maria]]. Realizing that Ida-Maria liked Elias, [[spoiler:Nora]] started a rumor that someone had taken pictures of Ida-Maria naked after she passed out during a party and showed them to the entire school, causing her to be ostracized and [[SlutShaming slut-shamed]] by everyone until Nora became her only friend. She then told Ida-Maria that Elias and his friend Atte had taken the pictures and thus deserved to die, starting the events of the movie. Her plan to MurderTheHypotenuse would have made her the BigBad of the story if they didn't [[CollidingCriminalConspiracies just happen to encounter]] a genuine {{slasher}} killer.

* [[NunTooHoly Madamede Chelles]], the third mother superior in Denis Diderot's "The Nun" (1796), tries to seduce the protagonist, Suzanne, and goes insane after Suzanne starts shunning her, following the advice of her confessor.
* An example from 1895 is Mary Wilkins Freeman's story "The Long Arm" (probably inspired by the sensationalistic media coverage of the Mitchell/Ward murder case in 1892). Here, Phoebe Dole, a terrifying, powerful, manipulative woman, has been maintaining another woman in subjection for years, and when this woman finally takes steps to leave her for a man, Phoebe bloodily [[MurderTheHypotenuse murders the hypotenuse]], pinning the crime with diabolical cleverness on an innocent party. She attempts to justify her crime (in a VillainousBreakdown) by saying that she's defending her domestic happiness, but this "happiness" is presented as perverted. She's described as physically monstrous as well as morally — she's the one with the abnormally "long arm" of the title — as one critic put it, "a desperate figure of lesbian evil, a hypocritical, sick, self-absorbed carnivorous flower."
* 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.
* Subtext in Nella Larsen's ''Literature/{{Passing}}'' (1929). The egotistical, needy, manipulative Clare, a practiced seducer, uses her beauty and charm to fascinate Irene before setting out to take over Irene's life and husband. [[spoiler:Irene eventually murders Clare while still attracted to her.]]
* Mrs. Danvers from Daphne du Maurier's ''Literature/{{Rebecca}}'' (1938).
* In ''Literature/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.
* Creator/JosephineTey's ''Miss Pym Disposes'' (1948) is set in a women's college of physical culture, where Miss Pym, an amateur psychologist, is paying a visit. At the start of the book, she has a conversation with Desterro, another outsider, a sophisticated woman with many male lovers, who tells her that the college's stressed students are sexually undeveloped or misdeveloped, since they have crushes on their female teachers and intense friendships with one another. The naive Miss Pym thinks that she's never seen anything so normal and healthy as these students in her life.
-->'''Pym:''' Do you suggest that Miss Nash is not normal?\\
'''Desterro:''' Oh, Beau. She is a strong-minded creature, and so has suffered less, perhaps. But would you call her friendship for Innes quite normal? ''Nice,'' of course (''she added hastily''), quite irreproachable. But normal, no. That David and Jonathan relationship. It is a very happy one, no doubt, but it (''she waved her arm to summon an appropriate word'') -- it ''excludes'' so much.
::Sure enough, by the end of the book, not only is it clear that there is a lot of psychological mess at the college, but it turns out that Miss Nash has committed murder for Miss Innes's sake.
* Kathryn Hulme's ''The Nun's Story'' (1956) strongly implies that the Archangel Gabriel (an inmate in an insane asylum) is one of these, not least because [[spoiler: her assault on Sister Luke appears to be attempted rape.]]
* One of these features as a villainess in the Literature/JudgeDee novel ''The Chinese Maze Murders'' (1957).
* 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.
** The third book has Beebo [[spoiler:kill a dog in order to keep Laura. It doesn't work. She wakes up to herself in the fourth book, by which time Laura has married Jack--although both of them remain gay--and had a daughter. Fortunately, Beth is there for Beebo]].
* Creator/AgathaChristie had one of these as the murderer in ''Nemesis'' (1971). The lady couldn't accept her 'protege' leaving her for a man.
* In ''Daemon in Lithuania'' (1973), some characters put on a play that contains [[TropeOverdosed 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 Freudian long cigarette holder. Finally, she tossed it on to the ground, [[GroinAttack stamped on it]], and flung herself on to her frivolous friend's couch, intending to strangle her..."
* Andrea from ''The Zone'' series (1980 - 2007) of WorldWarIII novels by James Rouch, is certainly ([[SociopathicSoldier psychopathic if not psychotic]]) and is widely assumed to be a lesbian by the other soldiers because of her contempt for men. Eventually however she forms a sexual relationship with Major Revell.
* Creator/RobertWestall's ''Literature/FuturetrackFive'' (1983) has a mild parody; Dronfield Biological Warfare Research Centre is staffed entirely by female Techs. All of the male Techs believe them to be Psycho Lesbians.
* Lizzie Borden has inspired many writers to speculate about why she killed her parents, and psycho lesbian motivations are among the lot. Evan Hunter's novel ''Lizzie'' (1984) portrays her as driven to murder after, having been seduced by an aristocratic lesbian in Europe, returning home in a state of sexual frustration and being surprised in a tryst with the maid by her parents. Another novelization, ''Lizzie Borden'' (1990) by Elizabeth Engstrom, has the title character in an incestuous relation with her father and sharing a bisexual lover with him.
* One of the more uncomfortable subplots of Creator/TomClancy's ''[[Literature/JackRyan The Cardinal of the Kremlin]]'' (1988) features an American female rocket scientist who essentially hands her male co-worker over to [[UsefulNotes/MoscowCentre the KGB]] in order to (clumsily) attempt to [[ComfortingTheWidow seduce the guy's wife]].
* ''Literature/TheWheelOfTime'' has Galina Casban (introduced in 1994), leader of the Aes Sedai's [[DoesNotLikeMen markedly male-averse]] Red Ajah [[spoiler:and secretly a high-ranking servant of the Dark One]]. She had a reputation for using her authority to pressure other Aes Sedai into relationships, has some highly questionable dealings with Accepted students under her authority, and takes a break from brutally torturing [[spoiler:Rand]] to ogle a woman nearby. [[spoiler:She later gets some [[BreakTheHaughty vicious]] SexualKarma from Therava, another Psycho Lesbian who enslaves and utterly dominates her.]]
* [[spoiler: Ruth Vigers]] in ''Affinity'' (1999) by Sarah Waters. [[spoiler: An Evil Mastermind con artist who gets her jollies preying on young girls while dressed as a male spirit. It's implied she's something of a control freak with her girlfriend, femme moll Selina.]] Perhaps an attempt at [[DeconstructedTrope deconstructing]] this trope, by putting it in a social context. The protagonist of the book, whose lesbian impulses are tightly repressed, is mentally disturbed in other ways.
** It's also worth remembering that [[spoiler: Selina was an accomplished confidence trickster long before she met Vigers, and only started working with Vigers in the first place because she convinced Vigers' mistress, Mrs. Brink, that she was Mrs. Brink's dead mother reincarnate]]. She only ''seems'' less culpable because [[spoiler: her actions are viewed through her own eyes or Margaret]]'s, and neither is exactly an unbiased observer.
* [[spoiler:Ktarka Zamlon Torin]] in ''Beyond Varallan'' (2000), the 2nd book in S.L. Viehl's ''Literature/{{Stardoc}}'' series, is first person in her planet's known history to have homosexual tendencies ''at all''. [[spoiler: The first lesbian in Jorenian history turns out to be a drug-fueled rapist and murderer with oddly vague reasoning for her infatuations...]]
* [[spoiler:DI Jan Shields]] in Val [=McDermid=]'s ''The Torment of Others'' (2006) is a particularly nasty example who [[spoiler:uses MoreThanMindControl on a succession of mentally-challenged young men to force them to kidnap and torture prostitutes for her viewing pleasure.]]
* Lisbeth Salander is portrayed as this by the Conspiracy attempting to discredit her in ''[[Literature/TheMillenniumTrilogy The Girl Who Played with Fire]]'' (2006).
* Esme and Liza, [[spoiler: the so-called Beard Killers]], in Alex Grecian's ''The Yard'' (2012). They were DrivenToMadness after Esme was brutally assaulted by UsefulNotes/JackTheRipper.

[[folder:Live-Action TV]]
%%* ''Series/BuffyTheVampireSlayer'': Dark Willow, natch.
* An episode of ''Series/LawAndOrderSpecialVictimsUnit'' 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.]] Also featured is a lesbian SoapboxSadie who, while not quite psychotic, is very loud and [[DoesNotLikeMen rude to every man she meets]]--[[spoiler:which turns out to be a cover for the fact that she's secretly bisexual]].
* An episode of ''Series/{{Torchwood}}'' had a [[NinjaPirateZombieRobot psycho lesbian from]] [[RecycledINSPACE space]].
* Subverted in ''Series/{{Heroes}}'' [[spoiler:The audience is led to believe that Gretchen Berg is perpetrating acts of violence against anyone who tries to get close to Claire, including her roommate Annie and members of a sorority. She also Facebook-stalks her. However, though she did have a crush on Claire, it is revealed that the acts of violence were in fact perpetrated by someone working for the main villain, Samuel.]]
* "[[ButchLesbian Daddy]]" from ''Series/PrisonBreak: The Final Break''.
* Mickie James from Wrestling/{{WWE}} started out as Trish Stratus's psychotic lesbian stalker.
** Unlike many of the other examples, Mickie James was embraced by the fans. It helped that along with being a genuinely talented woman, she was funny in the role and likable.
* The Pink and Yellow Psycho Rangers come off as this in an episode of ''Series/PowerRangersInSpace''.
* In the episode "Good Night, Dear Heart" of ''Series/QuantumLeap'', Sam tries to determine the cause of death of a young woman who was apparently drowned. [[spoiler: It turns out that the young woman was murdered by her lesbian lover because she fell in love with a man.]]
* Several in the first two seasons of ''Series/{{NCIS}}''. Since the second season ended, their problem with Psycho Lesbians seems to have disappeared:
** In "Conspiracy Theory", the killers turned out to be two women who had been committed to a mental hospital, where they now have sex with each other.
** In "Lt. Jane Doe", a lesbian petty officer killed and raped her lover and then implanted semen from an old cold case into her so they would think the rapist had struck again. It probably would have worked if they hadn’t figured out the original rapist's identity. (In a bit of a ContrivedCoincidence he had just gotten out of a Canadian prison a month before and moved back to Virginia). It turns out he had died a few weeks before the murder.
* ''Series/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.']]
* Lydia Hart on ''Series/{{Hollyoaks}}''. After being dumped by Sarah, she sent dead flowers to herself pretending they were from her ex-girlfriend Charlotte, making Sarah get back together with her out of pity. Not long after that she tried to murder her love rival Zoe during a skydiving holiday by sabotaging her parachute, but the parachutes were handed out in a random order and Sarah was killed instead.
* Several characters of ''Series/CuteyHoneyTheLive''. The title character, Honey, is lusted after by another female main character, Yuki. Yuki gets extremely jealous and possessive 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; proceeding 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. For added '''wrong''', a good deal of Mayumi's fights with Miki consist of one groping the other.
* ''Series/{{Smallville}}'': Tina Greer, Lana's only lesbian StalkerWithACrush of the Week.
* "Somebody's Watching," an early episode of ''Series/CriminalMinds'', had [[spoiler: Maggie Low as the unsub, a college friend and longtime stalker of Lila Archer.]] She confronts Lila and Spencer at gunpoint in the end, furious because Lila and Spencer are attracted to each other.
* The murderer in one of the season 5 ''Series/{{Psych}}'' episodes, who is also an aversion of NobodyOver50IsGay.
* The ITV ''Series/{{Marple}}'' adaptation of ''Literature/TheBodyInTheLibrary'' actually changed the identity of the killer from Christie's original plot in order to cater to this trope.
* Carmen on ''Series/SouthOfNowhere'' is supposed to be portrayed as this but the worst thing she does is push Spencer into a wall by accident when fighting over the fact Spencer still has feelings for Ashley; and she immediately apologizes for it. She is popular in the fandom; instead of shipping her with Spencer, many people prefer her with Ashley's sister Kyla.
* In the "Living Witness" episode of ''Series/StarTrekVoyager'', where the Kyrians misremember Our Heroes as brutal and sadistic mercenaries, Janeway's evil alter ego is depicted as unfeminine and domineering. This is emphasized by black leather gloves and a short butchy hairdo (in contrast to the character's usual flowing locks).
* An example from before the 1990s - in ''Series/TheStreetsOfSanFrancisco'''s "Once A Con," a convict on a day release programme is under suspicion of having murdered a student on campus. [[spoiler: She was killed by the roommate of her friend - she thought the victim was planning to take her friend (who she loved) away from her. It was an [[AccidentalMurder accidental killing]], with the goal being to "just" scar her.]]
* [[spoiler: Teased but ultimately averted]] in the ''Series/MurdochMysteries'' episode "Double Life". [[spoiler: It is first suggested that Dr Grace's girlfriend Lillian Moss killed her ex, Gladys, and Gladys's husband, then - once it turns out Gladys is FakingTheDead - that Gladys killed her husband and later shot Lillian for rejecting her. It eventually transpires that the only psycho in the case is Gladys's husband, who Gladys ''thought'' she'd killed to protect Lillian, and who later returned, killed Lillian, and tried to reclaim Gladys at gunpoint]].
* Discussed in ''Series/{{Longmire}}'' by Tamar Smith, who gets very peeved at the (false) insinuation that she kidnapped [[spoiler:Donna]] because she was infatuated with her.
* Suzanne "Crazy Eyes" Warren from the Netflix original series ''Series/OrangeIsTheNewBlack'' is gay, and also definitely has mental problems, as her nickname might suggest. She is also a deconstruction, in that she is not a bad person, per se, nor is she even a full-blown psychotic, although the prison does periodically have to confine her in the psychiatric ward.
** Suzanne gets intimate with one in a later season who is NotGoodWithRejection and engages Suzanne in a fight because of it and from a guards manipulations. She also causes the guard (Humps) to have a stroke by blowing into his IV tube for his sadism towards them in the previous season and his homophobia towards them.
** Mazall in season 2 is friendly towards Piper, but in a very intense manner. Upon Piper's arrival, Mazall immediately asks her the details of her birth, as she is heavily into astrology. After Piper, following a signal from Hill, refuses to tell Mazall the time she was born, Mazall climbs into Piper's bunk during the night and licks her face until Piper gives away the information. The next morning, Mazall admits she has "manic rage" issues and once bit off her ex-girlfriend's tongue and swallowed it.
* In the ''Series/FatherBrown'' episode "Lair of the Libertines", [[spoiler:Madame Chania]] turns out to be a [[ForTheEvulz thrill-seeking]] StrawNihilist who enjoys HuntingTheMostDangerousGame and who abuses her ExtremeDoormat girlfriend to the point of [[spoiler:using her as a FallGuy]].

* The video for Music/AmandaPalmer'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]].
* The unnamed narrator in Music/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]].
* One possible interpretation of Music/{{PJ Harvey}}'s "Catherine" from ''Music/IsThisDesire'', where a woman is singing about her envy and anger towards the titular character, and [[MurderTheHypotenuse plans to murder her current lover.]]
* Music/{{Vocaloid}}:
** In the song ''Escape the Princess'', Gumi tries to run away from Miku, who plays one of these. [[DownerEnding It doesn't]] [[RapeAsDrama work out]].
** The song ''Marie-Luise'', sung by Lily, is about a girl in love with her childhood friend, who's married to someone else. [[IfICantHaveYou Things get worse from there...]]

* The 1920 surrealist play ''Les Détraquées'' ("the deranged women") features lots of depravity in a girls' school, including two lesbians, the director and the dance teacher, who torture and murder a student.
* ''Theatre/TheMiracleWorker'' alludes to Psycho Lesbians existing in the asylum [[spoiler:which Annie Sullivan grew up in]]: "The asylum? [...] There were [...] some of the kind that keep after other girls, especially the young ones."
* Inez in ''Theatre/NoExit'' is a lesbian, and she's open about living for the pain of others, but her orientation seems fairly incidental to her character. She is a very well-made example since the other hetero characters are no less cruel than her and she is psycho because she takes the lesbian part along with the selfishness to their logical extremes. This means that she pathologically hates men and sees them as competition, so much so that she is willing to ''kill''.

[[folder:Video Games]]
* The InteractiveFiction game ''VideoGame/TheBlindHouse'' has heavy subtextual hints at an attraction between its two main characters, Helena and Marissa, and both of them are clearly pretty unstable in different ways -- but especially Helena, who has just killed a woman who is implied to have been her lover. What really takes it into this trope's territory, though, is TheReveal that [[spoiler:Helena has been stalking Marissa and trying to trap her in her own house]], and the fact that in [[MultipleEndings one possible ending]], [[spoiler:Helena kills Marissa too. While lying on top of her on her bed. And then cuddles with the corpse]].
* Selena in ''VideoGame/{{Damnation}}'' definitely fits this trope.
* Inverted in ''VideoGame/ADanceWithRogues'', in which the lesbian characters tend to be nicer.
* Amongst the AxCrazy bosses of ''VideoGame/DeadRising'', Jo Slade stands out. A sadistic police officer who brutalizes young women, she was one of the creepiest enemies in the game.
* [[spoiler:Paragon Branka]] of ''VideoGame/DragonAgeOrigins'' seems to qualify as this trope. On the other hand, [[spoiler:she was married to Oghren]], so it is possible that she is a DepravedBisexual.
* Played for {{squick}} in ''VideoGame/HauntingGround'', the (technically) [[{{Asexuality}} asexual]] [[ArtificialHuman Homunculus]] [[spoiler: Daniella]] could qualify. Insanely jealous of Fiona's [[spoiler: [[LifeEnergy Azoth]] and her ability to bear children]], she gropes her in her sleep before ''breaking a window with her own forehead'' to get a piece of glass sharp enough to dismember the girl.
* The antagonist [[spoiler: Wendy]] from ''VideoGame/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]].
* Claudia Wolf of ''VideoGame/SilentHill3'', [[EpilepticTrees possibly]]. She seems to be obsessed with Heather, or rather with Alessa, in more ways than one.
* [[ButchLesbian Lenni]], the leader of [[TheCracker Prime]]_[[{{Troll}} Eight]], in ''VideoGame/WatchDogs2''. A PsychopathicWomanchild who goes after [=DedSec=] for being [[SillyRabbitIdealismIsForKids hacktivists]] and has a furious rant about how they're no different from her, she goes on a swearing rampage every time her plans are foiled (which sounds incredibly childish), and her favorite haunt happens to be a gay bar in [[{{Gayborhood}} the Castro]] (The game ''is'' set in San Francisco).
* ''VideoGame/WindChildBlack'' has Azura, an immortal witch obsessed with healing her wounded wife. Her initial reaction to meeting the protagonist is to throttle the girl. It's implied that she was relatively sane before she became immortal. Her wife, on the other hand, is a subversion, being much more rational and pleasant to be around.
* If [[LoveInterest Sempai]] is a girl, this perfectly describes {{Yandere}}-Chan from ''VideoGame/YandereSimulator'', but what did you expect from a game named Yandere Simulator? Yui Rio, TokenEvilTeammate of the Rainbow 6, is also implied to be a lesbian, as some promo art shows her sexually harassing Yuna Hina by trying to grab her rear.

[[folder:Visual Novels]]
* [[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.
* Sousou from ''VisualNovel/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.
* Downplayed in ''VisualNovel/LiarLiar 2''. Miho and Yukari are a couple however them being violent is unrelated to it. Yukari is [[BiTheWay bisexual]], however Miho's sexuality has never been hinted about besides her liking Yukari. They're both serial killer [[TeensAreMonsters teenagers]], but then again almost every character in the game kills someone in the {{Bad End}}s. Miho [[StartOfDarkness started]] killing due to her StalkerWithACrush while Yukari has apparently been cruel her entire life ([[spoiler:she's even killed everyone she's been with since elementary]]) but her boyfriend leaving her for [[SiblingTriangle her sister]] caused him to kill him in jealousy ([[spoiler:and to [[BigBrotherInstinct protect her sister]]).
* ''VisualNovel/UminekoWhenTheyCry'' [[spoiler:offers a rare ''[[UnholyMatrimony mutual]]'' example with [[BigBadDuumvirate 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 nonetheless.]]

[[folder:Web Animation]]
* Yukari and Yuyuko from ''VideoGame/{{Touhou}}'' are like this in the 18+ version of the ''Music/{{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)

[[folder:Web Comics]]
* In ''[[http://adayoflucy.thecomicseries.com A Day of Lucy]]'', It is likely from this [[http://adayoflucy.thecomicseries.com/comics/10/ strip]] that Natalie is one.
* Lemon and Lime from ''[[http://evilplan.thewebcomic.com Evil Plan]]''. The inseparable supervillainesses refer to each other as their "wives," and while they seem to be happy and perky, the right conditions are all that needed to let the unsettling mania show...
* In Chloe's web comic ''Webcomic/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.
** Whether or not Roomie uses her hosts is debatable — "taking them for granted for everything until she gets bored and moves on" is an extreme, even far-fetched interpretation of her behavior even in the early chapters — but she never steals from them. The one time she's shown walking out in someone else's clothes, she couldn't get at her own, and she returned them at the end of the chapter. Likewise, the money she took from the table was specifically intended for food for Lillian, which Roomie bought, prepared, and laid out for her. Even her conscience — at least, her remorse that someone got hurt from misinterpreting her usual flirtatiousness — is demonstrated by the end of the first chapter.
* Chi, Aku's daughter in ''Webcomic/GrimTalesFromDownBelow'', [[StalkerWithACrush specifically towards Mimi]].
* Yuki, from ''Webcomic/MenageA3'', plays with the trope. She not only has a [[HollywoodPsych psychological disorder]] which means that she sees all male sex organs as "Naughty Tentacles", she tends to go into berserk fugue states in which she [[GroinAttack attacks]] said "Tentacles" ''with the intent of utterly destroying them''. She played StalkerWithACrush to her bisexual ex-girlfriend Zii, and for a while turned protagonist Gary's life into a living hell, forcing him to make out with his gay roommate (thanks to a typical deranged misunderstanding on her part) and blackmailing him into illustrating her manga script. However, the situation was more complicated than this sounds. Aside from the facts that Yuki is clearly far more crazy than evil, and that Gary rather masochistically fell for her, Zii declared from the first that she was actually bisexual under the insanity, the Cast Page confirmed this, and in due course Yuki discovered feelings for Gary, and made rater intermittent attempts to find a cure for her psychosis. The path of that possibly-true love turned out to be far from smooth, but Yuki has evolved away from the pure form of the trope.
** She also has a sexual relationship with her female band partner even though both of them tell the other that they hate them at every opportunity -- even during sex.
* One of [[ManicPixieDreamGirl Vanessa's]] exes in ''Webcomic/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."
* Gail Swanson, the VillainProtagonist of ''[[http://whenshewasbad.smackjeeves.com/ When She was Bad]]''.
* In ''Webcomic/YuMeDream'' Sadako is a pretty perfect example. That being said, [[CastFullOfGay other characters]] provide more positive depictions of homosexuality and bisexuality.

* Fire Burial from ''WebOriginal/Brennus''. She'll burn off the genitals of any male who propositions her.
* WebVideo/DiamandaHagan. PlayedForLaughs.
* Pinkie Pie from ''WebVideo/MyLittlePonyTheMentallyAdvancedSeries'' is easily the most cruel and violent of the Mane 6. She has, among other atrocities: almost sprayed fluttershy with Aqua Regia (known for its ability to dissolve gold), has enjoyed the suffering of Rarity, and asked Twilight to make Fluttershy cry for a vial of holy water. She has also hit on most of the main cast (all female), and has outright stated "Pinkie is lesbian".
* Lyn "Laeil" Burbank of ''Roleplay/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]]. [[spoiler: The last thing she sees before she dies is a hallucination of forementioned female friend forgiving her.]] Reiko Ishida of version 4 is an inversion: while she is a prominent player, one of her more sympathetic qualities is her relationship with Sarah Xu, and after CharacterDevelopment she starts to be concerned about what Sarah thinks of her actions.
* ''WebVideo/TheVeronicaExclusive'' gives us Jane. SerialKiller. AxCrazy. {{Yandere}} extraordinaire. Hopelessly in love with Veronica. Incidentally, Veronica is [[BiTheWay bisexual]] and ([[SanitySlippage usually]]) sane.
* Missy from ''WebOriginal/TheWarComms''. At first she was just a lesbian who happened to be a psycho, then a psycho who happened to be a lesbian. Then she started making some suggestive comments about Esmeralda and Trisha, [[FoeYay whom she claims to despise]] and, well.
* Website/{{Pixiv}} has the [[https://www.pixiv.net/search.php?word=クレイジーサイコレズ "Crazy Psycho Lesbian" tag]] for works including this sort of character.
