->''"Never let the crazy outweigh the hot."''
-->-- Regarding Mathilda, of ''VideoGame/MadWorld'' and ''VideoGame/AnarchyReigns''

This is someone TheHero used to be with, but broke it off. Said Ex is NotGoodWithRejection.

You can expect the Ex to become a StalkerWithACrush. Many times, the Ex will [[FaceHeelTurn become a villain]] because LoveMakesYouEvil. Despite the obvious gender differentiation in the title, it is not AlwaysFemale.

Oh and [[GodHelpUsAll God help]] anyone our hero dated after this loon. [[SecondLove They]] ''[[CrazyJealousGuy will]]'' [[ClingyJealousGirl suffer]]. Sometimes the hero [[IfICantHaveYou will be targeted as well]].

There are, at times, sympathetic Psycho Exes. Such as, if the break-up occurred because of the hero being a two-timing jerk at the time, or if she called him ''once'' to ask for her stuff back, and [[WoundedGazelleGambit he went around telling everyone she "won't stop calling him," or told everyone that she cheated on him.]]

This is about the person who went nuts '''because of the break up'''. We also have tropes for: someone the hero [[DatingCatwoman knew was evil]] when they started dating, someone who [[BastardBoyfriend turned out]] to be a psycho within the relationship, and someone who was turned into a psycho out of the blue [[DieForOurShip in order to]] [[DerailingLoveInterests kill off the relationship]].

[[folder:Anime and Manga]]
* Subverted in ''Manga/HayateTheCombatButler'', where [[spoiler: Athena]] ''seems'' to be one of these... [[spoiler: It turns out DemonicPossession and being a LonelyRichKid really messes with one's mental stability. She seems to be better now that she's free.]]
* Aizawa from ''LightNovel/{{Sukisho}}''. More to the point, he's a psycho ex-boyfriend.
* Yuri Kim in ''Manhwa/FaeriesLanding'' is just about the personification of this trope, and even physically scarred the hero just to see him squirm.
* Dante of [[Anime/FullmetalAlchemist the 2003 anime version]] of ''Manga/FullmetalAlchemist'' is the sociopathic, mass-murdering ex-lover of Hohenheim.
* [[AlternativeCharacterInterpretation A possible interpretation]] of [[TheDeterminator Kyouko]] from ''Manga/SkipBeat''.
* ''Anime/GhostInTheShellStandAloneComplex'' has an interesting example where an ex of Pazu[[note]]The same person that said he never sleeps with the same woman twice.[[/note]] dons a perfect prosthetic duplicate body of his and frames him for two murders. It goes further in that she claimed to still love him, but believed that by being inside an exact copy of his body she had his "ghost" inside of her. [[YouHaveOutlivedYourUsefulness Then she tries to kill the real Pazu.]] It's not made explicitly clear whether the real Pazu won the fight.
* While not in total control of her faculties, Queen Mirage of ''Anime/HappinessChargePrettyCure'' is certainly this. [[spoiler:Turns out she was a ShrineMaiden who fell in love with Blue 300 years ago. While he returned the feelings, he felt that, as a God, he shouldn't be attached to any one person and rejected her. She didn't take it too well, especially since it seems that Dark Mirror took control of her because of it.]]

[[folder:Comic Books]]
* Ray Palmer and his ex-''wife'', Jean Loring, in ''ComicBook/IdentityCrisis''. She gets committed to Arkham Asylum at the end. (Despite, er, not even living in the same state. Apparently there are no other asylums in the DCU.)
* [[ComicBook/TheFlash Wally West's]] ex-girlfriend Frances Kane, who returns as the psychotic villain Magenta. However, her violent insanity is actually an [[ComesGreatInsanity unfortunate side effect of her powers]].
* Gender-flipped (and foisted on her boyfriend) in Canadian [[{{Animesque}} mangaesque]] series ''ComicBook/ScottPilgrim'', where the main antagonists are [[MilkmanConspiracy the League of Ramona's Evil Ex-Boyfriends]] (oh, and one [[PsychoLesbian Ex-Girlfriend]]), whom Scott must defeat in various bizarre fight scenes in order to continue dating his LoveInterest.
** Played straight with eventual fights involving Scott's ex-girlfriends Envy and [[spoiler:Knives]]. For fairness's sake, apparently, Ramona handles these fights.
* [[IronMan Tony Stark]] broke up with Kathleen Dare because she was being too clingy. So, she shot and crippled him.
** When Tony is later assumed to have died from an illness she [[spoiler: shoots herself so she can join him in the afterlife.]]
* Red She-Hulk [[spoiler:a.k.a. Betty Ross Banner]]. One of Hulk's wives finally doesn't stay dead, and this happens.
* Kimura, ComicBook/{{X 23}}'s AxCrazy former handler, strongly comes across as a crazy stalker ex after Laura escapes her and the Facility. She's obsessed with getting Laura back, making several notable attempts to recapture her. When she finally ''does'' manage to retake her during Laura's stint on X-Force, she's actually ''licking her lips'' as she takes a ''chainsaw'' to Laura's arm for "being a bad girl."
* ''ComicBook/{{Transmetropolitan}}'' Spider's ex-wife had her head cryonically frozen with instructions not to thaw until presented with incontrovertible proof of his death. And attempted to engineer his murder so she wouldn't have long to wait.

[[folder: Fan Works]]
* "[[http://www.fanfiction.net/s/9060802/1/Days-of-Futures-Past-What-Does-That-Mean-It-Kinda-Sounds-Sexy Days of Futures Past What Does That Mean It Kinda Sounds Sexy]]" Naruto mentions to Superboy that his ex girlfriend would threaten to skin the flesh from his bones whenever he forgot to do the dishes
* [[ComicStrip/StarFox Fara Phoenix]] of ''VideoGame/StarFox'' fame is prone to becoming this whenever FanFiction has [[ArcWelding merged]] the series' [[VideoGame/StarFox1 two]] [[VideoGame/StarFox64 continuities]], attacking either Fox or Krystal - or both.
* ''Fanfic/ExtendedStay'' gives us Mistress's ex-boyfriend William Queen in Chapter 7. He jumps up on stage during her date with the Warden, loudly accosts her and even threatens her boyfriend ''at knife-point!'' It doesn't really help that he was an inmate at the latter's prison.

* The obvious example must be Glenn Close's character in ''Film/FatalAttraction''. The film that gave the world the term ''bunny-boiler''.
* ''Film/MySuperExGirlfriend'' was made on this trope. It would have done a lot better, if they put some actual effort into the plot.
* Done for humor in ''Film/TheBluesBrothers'' with Jake's ex-girlfriend (Carrie Fisher), whose revenge for being left at the altar involves plenty of StuffBlowingUp and [[{{BFG}} BFGs]].
* [[Film/WaynesWorld Wayne's]] ex-girlfriend Stacy is a psycho hose-beast. Played for laughs, as SlapstickKnowsNoGender.
* ''Film/ScottPilgrimVsTheWorld'' - see Comic Books above.
* Theodora in ''Film/OzTheGreatAndPowerful'', with the help of her sister's deceit.

* [[TheHero Tanis]] and [[TheDragon Kitiara]] have this kind of relationship in Literature/{{Dragonlance}}, and feelings definitely linger on both sides (though in Kitiara's case, those feelings aren't much deeper than "lust and amusement"). From a technical stance, Kit's less "psycho" than "amoral and ambitious", but she still fits the trope.
** Given how Kitiara becomes [[GreenEyedMonster insanely jealous]] after hearing that Tanis is traveling with his ex-girlfriend [[RebelliousPrincess Laurana]] (especially after hearing how [[HelloNurse incredibly beautiful]] Laurana is) and how this jealousy causes Kit to become obsessed with Laurana to the point of relentlessly stalking the elfmaid and trying to give her a FateWorseThanDeath, Kitiara definitely fits as a "psycho."
* Lanfear from ''Literature/TheWheelOfTime'' series. A somewhat unusual example since TheChosenOne she used to date has been dead for several millenia, so her stalking's a ReincarnationRomance.
* Senna of ''Literature/{{Everworld}}'' is a ManipulativeBastard witch who is Christopher's ex-girlfriend, and is David's current girlfriend for most of the series, and his ex-girlfriend at the very end.
** Not really an example: while she ''is'' a [[TheSociopath sociopath]] and also an ex-girlfriend, the only reason she dated either of them was because she's TheVamp and they seemed useful to her plans.
* Literature/{{Raffles}} - Jacques Saillard in "An Old Flame".
* Nately's whore in ''Literature/CatchTwentyTwo'' becomes insanely homicidal after [[spoiler:she's told that Nately has been killed]].
* Used masterfully in ''Literature/DeathOnTheNile'', where [[WomanScorned Jacqueline de Bellefort]] chooses a very unusual and effective method of revenge. Invoking this trope, everyone ''expects'' her to act [[LoveMakesYouEvil crazy and homicidal]], which is a major plot point.
* ''Literature/HeartOfSteel'' has Jim a male example, whose reaction to the idea that Julia might be breaking up with him is murderous rage, which only gets worse after he gets turned into a cyborg.

[[folder:Live Action TV]]
* ''Series/TheXFiles'': Fox Mulder had ''two'' of these -- the first one was mostly just annoying and appeared as NewOldFlame to dump him again, but the second one turned out to be working for the GovernmentConspiracy and having ''some'' kind of weirdly ambiguous relationship with the Smoking Man.
* For a few episodes Blair Waldorf on ''Series/GossipGirl'' becomes this to Chuck. Most people thought it was fair enough, since he was giving his new girlfriend incredibly expensive watches, crediting her with making him a better man and treating her like a queen, when he'd [[spoiler: whored Blair out to his uncle and then slept with her greatest enemy.]]
* ''Series/{{Torchwood}}'':
** John Hart, Jack's ex-"partner" who shows up in the second season premiere. He reappears in the finale, holding [[spoiler: Grey, Jack's long-lost brother,]] hostage and tearing [[AliensInCardiff Cardiff]] apart for no apparent reason but to get Jack's attention. [[spoiler: It turns out to be a subversion, as Grey is the one in charge and has a bomb fused to John's wrist, forcing him to obey when he'd rather be anywhere else]].
** ''Series/TorchwoodMiracleDay'': His boyfriend Angelo's Catholic {{gayngst}} leads him to do terrible, terrible things.
* And then, of course, there's the Master, the Doctor's EvilCounterpart in the original ''Series/DoctorWho''. The original seventies and eighties stories depicted him as the Doctor's EvilFormerFriend, but even then there was heavy [[HomoeroticSubtext Homoerotic]] FoeRomanceSubtext, and the twenty-first-century stories with Creator/JohnSimm and Creator/MichelleGomez dropped the "sub" and made it blatantly obvious that they, in their youth, had a '''very''' close relationship.
* ''Series/HowIMetYourMother'':
** Parodied in "The Platinum Rule": at the end, Barney assumes Wendy the Waitress is this. She is actually taking their break-up really well, but he interprets her total maturity about the matter as a facade hiding a desire to murder him--for at least two years.
** Being as the show focuses heavily on dating, a number of straight examples show up, as do a number of women who never quite become girlfriends.
** A fun variation comes up when Lily starts following the girl Marshall's interested in, making Lily, by all rights, the crazy ex. At the end, Marshall concludes that Lily is one of the craziest people he's known. It's the episode they get back together.
** Special mention should also go to Jeanette Peterson, the last girl Ted is dating before meeting the Mother. After the break up, she trashes Ted's apartment and throws a major part of the stuff in there out of the window - on fire! (Including [[spoiler:the red cowboy boots and Barney's Playbook.]]) And Ted can't even get help from the cops, because Jeanette is a cop herself, and [[DirtyCop not above abusing this to her advantage]]...
* ''Series/ICarly'': Lewbert's ex-girlfriend Marta Trundel in ''iFind Lewbert's Lost Love''.
* ''Series/{{Oz}}''. Unit Manager Tim [=McManus=] forms a brief liaison with prison guard Claire Howell. When he tries to break off the relationship she assaults him in his office (to the delight of watching inmates), then charges him with sexual harassment when he tries to fire her. Howell's later actions definitely cast her in the role of a villain -- she assaults (and in one case murders) inmates, as well as using them for her own sexual gratification whether they want it or not.
* ''Series/TwentyFour''. Two characters, [[spoiler:Jack and Tony]], dating the same person, [[spoiler:Nina]].
* Davina from Series/MaterialGirlTvSeries [[spoiler: its revealed at the end of the series that most of her attempts to hurt Ali were in fact directed at Marco, Ali just got in the way.]]
* Virginia from Series/SunsetBeach. She even tried to have her ex's current girlfriend impregnated by another guy using a ''turkey-baster''! in a [[CrowningMomentOfFunny memorable scene]].
%%* Havoc and Sakura in ''Series/{{Renegade}}''.
* ''Series/TheVampireDiaries'' has Katherine Pierce, who was a former love interest of both Stefan and Damon Salvatore during their human lives. Katherine enjoys torturing and playing with both Stefan and Damon and has threatened Elena numerous times. Katherine appears to be obsessed with Stefan in particular and seems to be both jealous of Elena and in competition with Elena for Stefan's affections.
* Mandy from ''Series/SecretGirlfriend'', to an extreme degree.
* Rose from ''Series/TwoAndAHalfMen'' both fits and subverts this. Although becoming friends with Charlie, she does manage to drive away his love interests and refuses to give up. Plus, every main character has called her crazy at some point. She's also pretty civil in her stalking, despite it being creepy. In the ninth season premiere it's revealed she murdered Charlie for cheating on her.
* After Dexter finally cut it off with Lila in ''Series/{{Dexter}}'', she [[spoiler: nearly killed him and his girlfriend's children]].
* ''Series/{{Frasier}}'':
** Niles's ex-wife [[TheGhost Maris]] probably qualifies, although more subtly: when she begs for him to come back to her, and he rejects her on the grounds that she has treated him like dirt all his life, she goes into a TranquilFury and proceeds to utterly screw Niles out of every cent he has with a team of {{Amoral Attorney}}s, just for the sake of revenge (she was filthy rich already).
** Also Niles' ''second'' ex-wife Mel, who after feeling justifiably humiliated when Niles abandoned her to run off with Daphne Moon, exacted her pound of flesh by insisting he go through the motions of marriage with her until such time as ''she'' felt they should seperate and divorce. Well, everyone said she was an expy of Maris...
* In ''Series/{{Zoey 101}}'', we have Chase's short-lived girlfriend, Rebecca. Admittedly, she was psycho while she and Chase were still dating; she demanded Zoey no longer have any contact with Chase, and that Chase stop being friends with Zoey. It was the reason they broke up. Rebecca, of course, took this to mean ''Zoey'' was the reason they broke up, and in a later episode ends up blackmailing her into doing all sorts of embarrassing things.
* In one episode of ''Series/BoyMeetsWorld'', Shawn becomes the target of ''three'' of these who band together to sabotage his latest relationship because they think he is leading her on like he led them on.
* Gabe of ''Series/TheOfficeUS'' is a psycho ex boyfriend. He becomes one after Erin breaks up with him. He follows Andy, (whom Erin really likes) to the men's room and threatens him and follows Erin into the ladies room and pleads for her to take him back.
* Vera Bates of ''Series/DowntonAbbey'' to the extreme. She refuses to let Mr. Bates divorce her, blackmails him for everything he owns and then pulls an ILied and tries to ruin his reputation and those of his girlfriend Anna and the family that employs them anyway, and finally [[spoiler: commits suicide in order to frame him for her murder.]] All this to a man who ''[[TakingTheHeat went to prison in her place]]'' for theft beforehand.
* Kirsty in ''Series/CoronationStreet'', when suffering boyfriend Tyrone leaves her for Fizz.
* On ''Series/MyNameIsEarl'', Earl had a girlfriend of three weeks named Jessie, as of the night he had his AccidentalMarriage to Joy. Jessie worked as a secretary at the bail bondsman's office Earl frequented. When Joy had an arrest warrant for failing to appear in traffic court 6 years later, Jessie puts herself through TrainingFromHell so she can get revenge on Joy for a) stealing Earl from her and b) knocking out her two front teeth. [[spoiler: It doesn't work, and she gets her veneers knocked out too.]]
* Lauren to Mitchell in ''Series/{{Being Human|UK}}''. [[JustifiedTrope Justified]] since Mitchell turned her into a vampire and then dumped her to deal with her new undead status herself.
* You would think that the CW show ''Series/CrazyExGirlfriend'' would be about this, but Rebecca Bunch, the main character, is actually a {{deconstruction}} of this trope: she has ''legitimate'' mental problems, including anxiety and depression and so when she ran into her ex-boyfriend Josh Chan, he reminded her of a time when she was truly happy. So she quit her job and moved across the country. However, for the first half of the season, she lied to herself, saying that she did this not because of Josh, but because she "needed a change." The theme song tells it like it is:
-->'''She's the crazy ex-girlfriend!'''\\
''What? No, I'm not.''\\
'''She's the crazy ex-girlfriend!'''\\
''That's a sexist term.''\\
'''She's the crazy ex-girlfriend!'''\\
''Can you guys stop singing for just one second?''\\
'''She's so broken inside!'''\\
''The situation is lot more nuanced than that!''
* ''Series/{{Spooks}}''. Quinn makes the mistake of confessing he's an MI5 agent to a woman he's seeing, who causes all kinds of problems when he tries to back out of the relationship (like printing his name and address on gay prostitute advertisement cards). Fortunately Quinn has attracted the attention of a BlondeRepublicanSexKitten from the CIA, who doesn't hesitate to abuse her power to scare off a rival.
* ''Series/{{NTSFSDSUV}}'': After Sam breaks up with his girlfriend, she threatens to blow up San Diego so she can force Sam to perform several tasks and marry her. He fails miserably, but decides to get in touch with her in prison.
* Jokingly played with in one ''Series/ThatMitchellAndWebbLook'' sketch -- Mitchell, recently an ex-boyfriend, doesn't seem particularly inclined towards this behaviour on his own, but everyone ''else'' suggests he handles the break-up in ways along this trope, ranging from writing bitch with weedkiller on her lawn, over killing her pet "in a weird way" to ''planting crack in her office desk'' (apparently a standard suggestion, as one of the others asks if the crack has already been mentioned when he joins the group).

* The music video for [[Music/JustinTimberlake Justin Timberlake's]] "Cry Me A River" paints the singer as this. [[https://youtu.be/mafXmZ150qw This]] video goes into more detail.
* "Crazy Ex-Girlfriend" by Music/MirandaLambert, of course.
* The title character of the Music/DixieChicks' "Goodbye Earl," who puts poor Wanda into intensive care after she gets fed up with his abuse and files for divorce. The girls themselves might also qualify given [[DeathByWomanScorned what they do to him in revenge for this]]. I wouldn't want to be those girls' next boyfriend.
* "Psycho Ex" by [[Music/WallOfVoodoo Andy Prieboy.]]
* Pretty much Music/AvrilLavigne's musical persona.
* Pink's "PleaseDontLeaveMe".
* Music/{{Paramore}}'s "(One Of Those) Crazy Girls".
* Music/{{Adele}}'s "Hello" features a woman who won't stop calling her ex and leaving messages on his answering machine or voicemail, even though the breakup was ''years'' ago, and he has learned not to answer when she calls. [[FridgeLogic (Apparently, he has never heard of Call Blocking, or considered changing his phone number.)]]
* In Music/TaylorSwift's "Blank Space", the narrator admits that her exes view her as a crazy ex-girlfriend :
-->''Got a long list of ex-lovers,\\
Theyíll tell you Iím insane,\\
But Iíve got a blank space, baby\\
And Iíll write your name.''
* "Before He Cheats" by Carrie Underwood is written from the perspective of a psycho soon-to-be-ex-girlfriend. It's about a woman believing her man is in the process of trying to score with another woman which drives her to vandalize his car and destroy his property.


[[folder: Tabletop Games]]
* ''TabletopGame/{{Pathfinder}}'' has Calistria. If she notices you, ''hope'' she loses interest before you do something to offend her - praying won't help because she's a ''god''. The deity of lust, trickery, and revenge, revered by elves for her changeable nature, fond of wasps due to their ability to sting people without harming themselves, and noted to be not simply vengeful but outright vindictive, [[GodOfEvil Mephisto]] considers her too unreliable to ally with.

* Theatre/{{Medea}} from Greek theatre. Yeah, it's OlderThanFeudalism.

[[folder:Video Games]]
* Jolene to Linebeck in ''VideoGame/TheLegendOfZeldaPhantomHourglass''.
* Catalina is one of these to Claude, the protagonist of ''VideoGame/GrandTheftAutoIII''.
** And also to [[VideoGame/GrandTheftAutoSanAndreas Carl Johnson]], although he never actually ''wanted'' to be her boyfriend.
* Adele from ''VideoGame/ArcRiseFantasia'' has a definite air of this about her. She was only ever a girlfriend in her own mind (and hopes), but evidently that was enough to trigger a violent murderous storm of {{Yandere}}.
* Kiki from ''VideoGame/GrandTheftAutoIV''.

[[folder:Web Animation]]
* ''WebVideo/SailorMoonAbridged'' makes the villain of TheMovie into a male version of this. [[HoYay Tuxedo Mask's ex boyfriend]] [[CrossesTheLineTwice from when they were ten]], to be precise.
* Adam Taurus in ''WebAnimation/{{RWBY}}'' is a male example. The episode "Heroes and Monsters" makes it quite clear that he didn't take it well when Blake left the [[WesternTerrorists White Fang]], and his [[TermsOfEndangerment referring to her as "my darling" and "my love"]] implies that they had some sort of romantic history together, [[WordOfGod which is outright confirmed on the directors' commentary]]. [[spoiler:He's now dedicated to destroying everything Blake holds dear and starts by lopping off one of Yang's arms.]]

[[folder:Web Comics]]
* Possibly ''Webcomic/MegaTokyo'''s Miho, depending on what side of the [[AlternateCharacterInterpretation emotionally crippled goth-girl or undead fiend debate]] you are on.
* Cassiel ([[{{Satan}} Lucifer's]] niece) is Rumisiel's in ''Webcomic/{{Misfile}}'', or at least she would be if she wasn't even more incompetent than [[TerribleTrio Team Rocket]].
--->"Haha! Sub-par snacks! FEEL MY WRATH!"
** Missi is an even milder version for Ash. Missi used to talk about ignoring Ash's wishes about not dating, but has settled into making sure that she's available if Ash's decision changes.
* Gwynn from ''Webcomic/SluggyFreelance'' almost [[TheEndOfTheWorldAsWeKnowIt destroyed the world]] trying to get revenge on ex-boyfriend Riff.
** Don't forget Oasis going after any female seen speaking to Torg. [[http://sluggy.com/daily.php?date=000425 Inanimate objects]] are not safe from her wrath if she sees them as rivals for Torg's love, either.
** Monica has gone far beyond Gwynn; refusing to understand that Riff broke up with her and using every MindScrew trick to keep him too intimidated and confused to get away. Subverted in that she has a method to her madness, double-subverted in that her ulterior motive is also crazy.
* Roxanne in ''ComicStrip/{{Candorville}}'' began as a ClingyJealousGirl, and some of the fandom thinks she still is and we're seeing things ThroughTheEyesOfMadness. If not, she's [[spoiler:a [[OurVampiresAreDifferent vampire]] prophesied to rule the world]], and the closest thing the strip has to a BigBad.
* In ''Webcomic/JetDream'', Raven Red reacts to the [[GenderBender sex change]] of her DatingCatwoman love interest Jack Thunder... poorly. While the newly-christened Harmony Thunder seems [[LipstickLesbian open to alternative possibilities]], Raven isn't, and takes an IfICantHaveYou position towards Harmony.
* ''Webcomic/TheInexplicableAdventuresOfBob:'' it turns out the reason Jean fell for NiceGuy Bob so quickly is that her previous relationship had been with BastardBoyfriend Slick Simmons, and she viewed Bob as his complete opposite. Slick has since returned as an obsessed, stark raving loon -- which, since he's also a brilliant scientist, is [[MadScientist problematic.]]
* Mona Montrois in ''Webcomic/CestLaVie'', over Louis and Tiffany. Her behaviour towards tiffany gets more and more unhinged until she ends up sectioned in a psychiatric hospital, and is afterwards released to intensive therapy, nearly driving her shrink insane.
* Damara Megido of ''Webcomic/{{Homestuck}}'' is an arguable example; learning that her (then) boyfriend, Rufioh, was secretly dating Horuss on the side drove her past the DespairEventHorizon, and Meenah's needling over the matter made her snap and go completely mad. In addition to killing Meenah and rendering Rufioh quadriplegic, it's heavily implied that she killed Horuss as well. It's implied that she still has lingering feelings for Rufioh, even though [[CaptainObvious he doesn't really want to date her anymore]].
* Discussed in ''Webcomic/QuestionableContent'' where Penelope expressed her dislike of the term, feeling it a cheap way of dismissing whatever actual problems the couple may have had.
** A downplayed example would be Angus's ex-girlfriend who we never actually meet but sounds like an unhinged Faye. Angus's flatmates threw a 'The witch is dead' party when they split up.
* Melissa in ''Webcomic/ElGoonishShive'', is an annoying example... except that it's been revealed that her motives are a bit more complex than that. Not to mention that she is fully aware that her attempts to win over Justin are pointless and do nothing but make her come off as annoying and quite possibly psychotic, but can't seem to stop herself.
** {{Defied}} with Ashley, she is fully aware that if she talked to Susan about staying away from Tom she would come across as a [[http://www.egscomics.com/index.php?id=1784 biased "crazy ex"]].


[[folder:Web Original]]
* Annabelle Wynters in [[http://underthevangogh.blissful-madness.com Under the Van Gogh]]. And that's putting it nicely.
* Shannon in ''WebVideo/EchoChamber'''s Trope Of The Week series has an entire episode dedicated to her psycho ex nature. She stalks him, threatens other girls he's seen with (Dana in particular), and seems to believe they are still dating. But the kicker? [[spoiler: She forced him to propose to her.]] Oh, and she regularly [[spoiler: cheats on him. Hooray for the DoubleStandard.]]
** One could take the above spoiler as [[spoiler: Tom proposes to her, but then gets cold feet and runs off. He takes Shannon back and now they have sex every so often.]]
* ''Literature/TheQuestportChronicles'': The Lord of Angels and Demons is a male example. He erases one woman's memory after she dumps him, and then [[DisproportionateRetribution destroys the only book that tells how to restore her memories]].
* [[http://www.cracked.com/video_18386_if-breakup-ballads-were-more-realistic-and-way-crazier.html This NSFW music video]] about a young woman [[spoiler: who feels compelled to post pictures of her ex's dick on the internet -- and elsewhere]].
* [[http://www.youtube.com/watch?v=ko_Mao6d1Mg&feature=g-u-u This video]] in a genderflipped example. It gets to the point where he's more or less breaking the laws of physics to get her back... and then he says that HE'S feeling smothered.
* Website/{{Cracked}}'s ''[[https://www.youtube.com/watch?v=cGIM8EPsaaI&lc=z22qvvtzbrrjgz5kvacdp430mq04aqy35uu24antqnpw03c010c America's Best Girlfriend: America's Worst Reality Show]]'' revolves around a woman who, having not taken her break-up incredibly well, goes to the trouble of (poorly) staging an entire fake reality TV show to try and humiliate her exe's new girlfriend. It fails disastrously on multiple levels.

[[folder:Western Animation]]
* Several times for Robert Freeman (Granddad) in ''WesternAnimation/TheBoondocks'', but thankfully not for repeating characters.
* Terra for Beast Boy in the AnimatedAdaptation of ''WesternAnimation/TeenTitans''.
** Hell, Terra ''period.'' She was much worse in [[ComicBook/TeenTitans the comics]]! When she had the Titans (aside from Nightwing) captured, Gar [[IKnowYoureInThereSomewhereFight pleaded with her]], only to have her not only laugh in his face but sneer that kissing him "made her want to puke." Even better is that she was actively boinking Deathstroke (who was actually ''afraid of her''). Poor Gar still can't fully acknowledge she was a traitor all along.
*** Comics Terra doesn't really apply to this trope since she was psycho before Changeling met her and any romance between the two of them was all an act on her part. Animated Terra however fits the trope to a [[IncrediblyLamePun T.]] She was pretty much on the neutral side of things, agreeing to sell the Titans out (well four of the five) as a favor to Slade for helping her control her powers, but not exactly on the evil side until Beast Boy told her she had no friends which turned her over the dark side completely [[spoiler: until her HeelFaceTurn three episodes later.]]
* Goliath and Demona of ''WesternAnimation/{{Gargoyles}}'', with emphasis on the "psycho"
** This is a case where feelings ''do'' still linger on both sides, but both characters recognize that they're now too different to ever be an item again (trying to kill each other almost every time you meet will do that to you). [[MisaimedFandom Doesn't stop the shippers]].
* Prof. Farnsworth and Mom in ''WesternAnimation/{{Futurama}}''.
** Notably, her insanity was there when they were dating. He just had a change of heart and couldn't stay with a megalomaniac.
* Trixie Tang from ''WesternAnimation/TheFairlyOddparents'' briefly became this to Timmy after he wished they were the only two people on earth in "Just the Two of Us!".
** While we're at it, Princess [[MeaningfulName Mandie]] is considered this to Mark Chang.
* Blackarachnia from ''WesternAnimation/TransformersAnimated'' is actually this to Optimus Prime, after [[spoiler: he and [[JerkAss Sentinel]] accidentally leave her behind on a spider-infested planet.]] Sort of, anyway: [[spoiler: she was actually Sentinel's girlfriend, but it's pretty obvious Optimus has a thing for her, which she returns after being mutated; she refuses to trust him, though.]]
* ''WesternAnimation/{{Sixteen}}'''s Lydia was Jonsey's ex; somehow she became a StalkerWithACrush to Wyatt.
** She thinks Wyatt and Jude are identical twins. That should tell you she's a little cracked. [[spoiler:When she meets Wayne, she thinks they're identical ''triplets''.]]
* WesternAnimation/DaveTheBarbarian's Ex, the [[CardCarryingVillain Evil Princess]] Irmoplotz.
--> '''Irmoplotz:''' Dating rule nº 1....NEVER BREAK UP WITH AN EVIL PRINCESS! [[EvilLaugh MHWAHAHAHAHAHAHA!!!]].
* Lola on ''WesternAnimation/TheLooneyTunesShow''. Bugs meets her on a tennis court and after the first date, decides that she's not right for him afterwards at least partially due to her being a StalkerWithACrush on him, and Lola [[MoodSwinger goes from being distraught about it]] [[StalkerWithACrush to believing that she's still involved with Bugs]] [[AndNowYouMustMarryMe to the point where she has Bugs (unwillingly) at the altar with her.]] Bugs is thankfully saved from the AndNowYouMustMarryMe situation she has put him in by her invocation of SpeakNowOrForeverHoldYourPeace on the grounds that she has decided that she loves Pepe le Pew.
** Then when Lola returned the relationship was SheIsNotMyGirlfriend for a few episodes before Bugs admits she's his girlfriend making Lola a psycho girlfriend.
* In ''WesternAnimation/StarVsTheForcesOfEvil'', Star has a ''demonic'' ex-boyfriend, Tom. When [[ShipTease she and Marco]] ended up doing a DanceOfRomance in "Blood Moon Ball", Tom starts BurningWithAnger and tries to incinerate the Earthling. A storyboard for that episode showed him threatening to destroy the Earth if Star didn't go out with him. A second episode had him try to manipulate Star [[spoiler: by getting a counselor to play on her fears]] but a callout from Marco made him realize he'd gone too far. [[spoiler: He decides to stop pursuing her after that.]]
