Murder the Hypotenuse

Go To
Don't try befriending Yukki.

"As I told Lady Freeze when I pulled her plug, this is a one-woman show."

Love Triangles are tricky business. Trust us, we've already done the math.

It can get particularly twisted when some sides of the triangle are completely one-sided. Bob is in love with Alice, but Alice not only fails to realize it but is already in a relationship with Chris. This is a classic recipe for drama (or humor) but sometimes, it goes too far.

Sometimes, somehow, Bob gets the idea that Chris is the one in the way of Bob's happiness with Alice, and if Chris were to somehow have an "accident", then surely Alice would come to love Bob instead. It's true — Love Makes You Evil and these characters are really Not Good with Rejection.

Not always the best thought-out plan, no. Sometimes, Bob may not even consider what would happen if Alice ever found out. In fact, in a lot of these situations, Bob doesn't even make any effort to hide his actions from her and seems to be convinced that she'll somehow fall in love with him as soon as he kills Chris.

If this isn't The Reveal for a Yandere, it's still very likely to be their most shocking moment.

Compare Opposites Attract Revenge and Comforting the Widow. This can overlap with Death by Woman Scorned if the hypotenuse in question is actually interfering with a relationship, and Better Partner Assertion, the leadup to this trope if the assertion is unsuccesful. Contrast I Want My Beloved to Be Happy, which may be subverted into this trope, and vice versa. Also compare the Scarpia Ultimatum, where the threat to murder the hypotenuse may or may not be carried out. Contrast If I Can't Have You…, for when it's the Cathetus (Alice, for those a little rusty on their geometry) who will be murdered. If this is done indirectly by setting the hypotenuse up to be killed, it's either an Uriah Gambit (if Bob does it intentionally) or Death of the Hypotenuse (if the intent is limited to the author). Extreme Sub-Trope of Removing the Rival.

When the official authors do this, it's Death of the Hypotenuse. When the fanfiction writers do this, it's Die for Our Ship. If the hypotenuse is a friend, it's Friend Versus Lover. If the character kills him/herself instead, it's Spurned into Suicide.

Note that the triangle must be a right triangle for this to apply. If it is an equilateral triangle, Polyamory occurs, though if you have a Psychotic Love Triangle going on, things may still not end well. And of course, this isn't meaning literally murdering the hypotenuse.

Beware of spoilers.

    Anime & Manga 
  • Subverted in Air Gear. It seemed that Ringo Noyamano had finally snapped on Simca — enough to attack her with unusual violence to get her out of the way in the "race" for Ikki's love, but then we find out she was putting the Migratory Bird out of action so she wouldn't hurt or kill herself trying to participate in the war for the Sky Regalia, due to her lack of combat skills.
  • Angel Sanctuary:
    • That's pretty much the motivation for Rosiel's schemes against Sara. Alexiel won't wake up permanently (shows up in moments of need but always gives back the control to Setsuna) because her current reincarnation is extremely happier. So Rosiel figures that if Setsuna could not be happy anymore... And yes, Rosiel and Alexiel are brother and sister, but that barely matters to the point of this trope. And even if it did, Sara and Setsuna are too, but that didn't keep her from being overjoyed when she believed to be carrying his child.
    • And on a straighter example, Layla set up her (successful) love rival to be killed by the man they both loved. Pretty cruel for all of the involved.
    • And while Raphael doesn't actually try to kill Setsuna, he does make it very clear he'd be glad to step in should Setsuna die.
  • The whole plot of Area 88 is that Shin's (now former) best friend sends him off to a war in the hopes that he'll get killed, so he can marry Shin's girlfriend, the daughter of his company's CEO.
  • Aria the Scarlet Ammo: Shirayuki Hotogi. A perfect Japanese beauty according to Kinji, except for one flaw — jealousy, which turns her into a berserker who assaults any girl approaching Kinji. When she finds out that Aria is living with Kinji she goes as far as trying to murder her. She is shown to love Kinji to the point that she will do anything for him.
  • Ask Dr. Rin!: Tokiwa tries this over and over for four episodes straight in the hope of having Meirin for himself. It's eventually revealed he was possessed.
  • Baka and Test: Summon the Beasts: Miharu's reaction to seeing anyone trying to come between her and Minami (who is not even interested in her) is to chase that person down and try to kill them.
  • Suruga from Bakemonogatari is infatuated with Hitagi. So much so that she starts stalking Koyomi after he hooks up with Hitagi and tries to beat him to death twice. Doesn't manage only because of Koyomi's amazing regenerating ability. I bet having been thrown around the room and then pulled back by your intestines would kill a normal person.
  • Basilisk: Kagerou is dead set on killing Oboro so she can have Gennosuke. (Much more in the anime than the manga, though.) Tenzen also wants to kill Gennosuke so he can have Oboro as his puppet wife, which would grant him full control of the Iga Tsubagakure.
  • Berserk gives us a non-Love Triangle scenario between Guts, his ill-fated lover Casca, and his inner beast. After the horrible events of the Eclipse that left Casca insane and incapable of loving Guts, Guts turned to hate and revenge in his sadness and despair. During a two-year time span, the dark emotions welling inside of Guts created the Beast, and the hellhound entity lived in disturbing harmony with Guts, feeding on his hate for the man who ruined his life so that one day, it may take over Guts' body and soul. However, the Beast's plan was interrupted when Guts put his hate and revenge aside for Casca, vowing to stay by her side and to try to find a cure for her insanity. The Beast does not like this, and has since then tried to get Casca out of the picture by trying to goad Guts into raping and killing her whenever he is mentally or emotionally weak. It's important to remember that Casca is also Guts' Morality Chain since she's the only reason why Guts refuses to give in to his dark side.
    • Depending on how you interpret their relationship, Griffith may have done this to Casca during the Eclipse to get to Guts. He also looked to be trying to finish them both off out of jealousy and anger at them betraying him by becoming a couple before the Skull Knight arrived to save them.
    • Griffith's no stranger to this trope even before the Eclipse. It's speculated by Judeau that the mission that he sent Guts on meant to kill Count Julius, who made an attempt on Griffith's life, may have been meant to kill Adonis, his young son (who Guts had accidentally killed during the mission in question) as well since Adonis was being groomed to marry Princess Charlotte, who Griffith wanted for himself in order to achieve his dream of having a kingdom of his own.
    • Also, Dark Magical Girl Rosine. Platonic or not, she has a very strong obsession with having her Morality Pet Jill stay with her after being separated for so long. Which she demonstrates by telling Guts that Jill is "hers" after realizing that Jill has somewhat of a crush on him. While attempting to kill him.
  • Black Butler:
    • In chapter 64, Undertaker attempts to kill Sebastian because he is making Ciel "miserable." He doesn't get a chance to. It's also worth noting that Undertaker has a considerable amount of Ho Yay towards Ciel and tends to lose his personal space around him.
    • In episode 17 of the first anime Sebastian has sex with a girl named Matilda to get information. When she finds out, Grell a male to female grim reaper with a crush on Sebastian is shown reacting jealously and writing down the girl's name in a next to die list.
  • Creed from Black Cat does exactly this to Saya when Train started developing a deep friendship with her. When that didn't manage to convince Train to come to him, Creed decides that it is now Train's Heterosexual Life-Partners fault and tries to kill him. He tries to do this to Sven and Eve later in the series.
  • Bleach:
    • Loli and Menoli attempt to do this to Orihime due to their boss having an interest in her powers.
    • Rukia's adoptive younger sister Homura, and to another extent her adoptive younger brother Shizuku, from the third movie wanted to kill all the Shinigami to keep them from coming between them and Rukia.
    • Orihime's hollowfied brother Sora also qualifies, trying to kill Ichigo (and Tatsuki, though less so) for taking his place in Orihime's heart.
  • Mayuri Konishi/Sarashina from Book Girl has traits of a yandere character. She is crazy about Akutagawa, with whom she went to elementary school. She admits to being jealous of Kanomata, who Akutagawa used to protect. When she suspects Akutagawa has feelings for his classmate Nanase Kotobuki, she says: "If so, I'll cut Nanse Kotobuki into ground beef!!!".
  • Liang Qi of Canaan appears calm and even-tempered, but is in fact unwavering, merciless, and very much obsessed with admiring and idolizing her "Sister" Alphard, to the point of being in love with her. To her frustration, however, Alphard does not reciprocate her feelings and instead ignores or even proceeds to ridicule her from time to time. Because Alphard seems to have taken a special interest in observing Canaan's reactions to every plot carried out by Snake, Liang Qi sees the elimination of Canaan as a way to win back Alphard's attention.
  • Clover: A thought B seriously got in the way of his romance with C/Ran. He also tried this on Gingetsu but failed.
  • Code Geass: Mao's treatment of Lelouch seems this way at first — C.C. originally made a contract with him, but abandoned Mao and made one with Lelouch instead. So Mao tries to kill him by manipulating a girl who has an unrequited love for Lelouch, turning into a temporary Yandere. It fails. Somewhat averted in that Mao offers to leave Lelouch alone if C.C. comes with him. Concerned with losing one of his best allies, however, Lelouch prevents this. After that, Mao directly goes after Lelouch in the most potentially destructive manner possible.
    • V.V., who looks like a kid but is Really 700 Years Old, became psychotically devoted to his younger twin brother Charles after their mother's death and killed his sister-in-law Marianne, Charles's favorite wife and his Knight, out of jealousy when they started getting too close.
  • Cute Devil: Naruse basically considers doing this to anyone who tries to get close to Akiyoshi. For example, he once threatened to stab a guy in the eye and later stabbed him in the chest when he found out he was hitting on Akiyoshi. And in another scene, he comments to a group of students, "If any of you touch him, I'll kill you all. This guy belongs to me."
  • This is essentially the main conflict in the second half of Da Capo, as Sakura tries to stop herself from subconsciously using her magical powers to either kill Nemu or drive her into insanity.
  • Maki in Darker than Black has a massive, crazy stalker-crush on his boss, Amber. Such an insane crush, in fact, that he completely abandons the usual Contractor "emotionless" act when he finds the guy Amber's in love with and tries to kill him even though if he'd succeeded, it would have ruined Amber's entire plan, resulting in a genocide.
  • Dawn of the Arcana: Loki has quite a few elements of Yandere, from threatening Caesar for insulting Nakaba and regretting that he didn't kill Caesar due to Nakaba's and Caesar's growing closeness in earlier chapters to killing Bella for threatening to have Nakaba either killed or raped by soldiers.
  • Deadman Wonderland:
    • Genkaku attempts this twice with the girls he thinks Nagi is interested in. He stabs Karako when she gives Nagi a Cooldown Hug, calling her a "shitty girl," and telling her not to touch Nagi. He also is shown to be very agitated and jealous when he insinuates that Shiro is someone close to Nagi, saying that Nagi "never learns," and that he'll just have to punish him again (which he tries by attempting to have Shiro and Karako raped). It's especially interesting to note that he was also the one that killed Nagi's wife in the beginning.
    • Masaru "Chaplin" Sukegawa was imprisoned after murdering a woman that her lover was caught with. Though she didn't specifically aim to murder that person, she still did it since her Branch of Sin manifested there.
    • Shiro did this in the first chapter/episode. She slaughtered Ganta's entire class out of jealousy, and then proceeded to show Ganta Mimi's severed head.
  • Death Note:
    • Misa once told Light "If I see you with another girl, I'll kill her!"
    • There's Kiyomi Takada, who was once Light's girlfriend. She really hates Misa for her involvement in Light's life and has suggested to Light that he should kill her.
    • And then when Misa and Takada have dinner together, Misa says that if Takada goes too far, she'll get the death penalty.
  • D.Gray-Man: Komui is implied to be in love with his sister Lenalee and goes nuts if there's even a hint of a guy being interested in her. In fact, a way to wake him up is to say "Lenalee's getting married." In the novel, when Bak (who also has feelings for her) gives Komui a tea that makes one tell the truth he has a breakdown when Bak asks Komui "Isn't Lenalee free to love who she wants?" He takes this to mean that Lenalee is in love with a guy and immediately pulls out a machine gun saying "Then I'll kill everyone and then die!"
  • D.N.Angel: In episode 23 Kael to Elliot so that he can have Freedert for himself.
  • Kei of Drug & Drop has obsessive feelings for Kazahaya, to the point of warning him that she would kill anybody who got in the way.
  • Both Mika and Namie of Durarara!! are Yandere for Seiji who's pretty crazy himself seeing as how he's in love with Celty's head. Mika has...plans for Celty's real head if she ever gets her hands on it and Namie actually tried to destroy it.
    • Professor Nasujima at Mikado's school clearly has a thing for Anri, which naturally Squicks the hell out of her. The same guy is also dating Haruna Niekawa (one of his former students). Or was. Haruna doesn't like that he's changed his preferences, so she gave Anri a visit and tried to kill her...
  • Elfen Lied: Lucy tries to suppress her instinctive desire to kill all humans so she can live happily with Kouta until she finds out he lied about the sex of the cousin he was going to a festival with and she saw them hugging, at which point she stops trying to be nice. She then proceeds to slaughter some people at the festival and kills Kouta's father and sister, and starts to go after Kouta's cousin Yuka, voicing her intent to kill her... but only stops once Kohta tackles her and she sees his tear-streaked face. She also isn't above acts of jealousy, once using her vectors to shove Yuka down when she saw her holding hands with him. Yes, she's VERY broken, but how broken she is is absolutely NOT an excuse for her killing or trying to kill innocent people just because Kouta pays more attention to them.
  • Ergo Proxy: An Entourage Auto Reiv belonging to Re-l Mayer, Iggy contracted the Cogito Virus and grew to become enraged at Re-l's lack of regard for him. He despises Proxies and blames Vincent for taking Re-l — his sole reason for existence — away from him. He develops an unusual state of both loving and hating Re-l, and locks her up to "protect" her, while he attempts to kill Vincent. However, an Auto Reiv belonging to a Proxy that Re-l killed, attempts to kill Re-l at the same time, causing Iggy to return to Re-l. The Auto Reiv goes into a self-detonation mode and destroyed much of Iggy except for part of his head (which left Iggy "conscious" to some extent). In the end, not wanting to see Iggy suffer due to the virus, Re-l shoots him and buries his head.
  • In Fate/Zero, Kariya Matou plans to do this with Tokiomi (the husband of his unrequited love Aoi). It's not purely for this reason, since Kariya blames him for handing him and Aoi's daughter Sakura over to the Matou's tortures (Though neither Aoi nor Tokiomi actually know what she'll be put through — the Matou leader, Zouken, is that much of a Bitch in Sheep's Clothing). Unfortunately, Kotomine kills Tokiomi first, but he sets Kariya up so Aoi (who actually does love Tokiomi) is led to believe Kariya did do it, and things get... messy.
  • A variant of sorts occurs in Fist of the North Star in regards to Shin, Yuria, and main hero Kenshiro. Shin is in love with Yuria, who is in a relationship with Ken. The variant here though is that Shin seems relatively self-restrained... until Jagi, Ken's arsehole brother, comes along and convinces Shin that Ken is too weak to protect Yuria and that Yuria would end up dead if she stayed with Ken any longer. Result? Shin and Ken fight, Ken loses, Yuria declares her false love for Shin to spare Ken's life and he takes her to his Southern Cross kingdom and some time later, Ken confronts him there.
  • Full Metal Panic!:
    • When it comes down to it, this is pretty much what Gauron tries to do to Kaname, because he's angry that Sousuke fell in love with her.
    • Sousuke gets a double whammy. He's in Leonard's way of both his plans and winning Kaname over completely as Sousuke and Kaname are in love. So of course, Sousuke is at the top of Leonard's hit list for two very big reasons.
  • Future Diary:
    • It's shown very clearly that Yuno Gasai (pictured above) would be all too willing to kill ANYONE who got in the way of her "love" with Yukiteru (including his mother and father). In fact, Yuno is even willing to kill anyone who is less than ten feet away from Yukiteru simply because they are less than ten feet away from him. Heck, she's even willing to kill Yukiteru AND HERSELF just to be with Yukiteru. Essentially, if she doesn't kill him the world will end and they will both die. If she does kill him then she can go to a different world's timeline, kill that timeline's version of herself, and then be with that timeline's Yukiteru. She doesn't seem to really mind that each of the world's Yukiteru are technically different people since her "love" for him is just to satisfy herself, at least until the end of the story, and she herself admits this.
    • A less lethal version of this seems to be executed by Aru Akise, who has a crush on Yukiteru. He goes through the trouble of researching everything about Yuno's background to try to dig up dirt on her, and exposes it to Yukiteru, telling Yukiteru to "get away from her." Chapter 50 seems to have confirmed this. When Yuno shows up, Akise glares at her, declares "I won't hand over Yukiteru to you!", and forcefully kisses Yukiteru. This sends Yuno into a rage and she comes at Akise with a knife. Akise tries to kill Yuno, because he believes she's trying to kill Yukiteru, and destroy her diary but ends up failing because it turns out Yuno had two diaries, and she ends up stabbing him. In the following chapter despite having just been stabbed by Yuno and sliced across the throat, Akise gets back up out of sheer determination (and love for Yukiteru) and texts an important message to Yukiteru even though Yuno ends up cutting off his head completely. He also nearly kills Yuno earlier in the manga with the two grappling for each other's diary phones and Akise trying to strangle Yuno.
  • The Garden of Sinners: Lio, who lusts after Shiki, wants to either kill or corrupt Mikiya to remove Shiki's Morality Chain.
  • Get Backers: Takuma Fudou to Ginji, over Ban. "When you're around, Midou doesn't even notice me. Midou's eyes are not on me... because you're in the way!"
    • Kazuki's gang, Fuuga (lit. "Elegance"), is really into the Ho Yay. There's some kind of Toshiki/Kazuki/Juubei Love Triangle, apparently; Toshiki even attempts to Murder The Hypotenuse, claiming that Kazuki never paid any attention to him when Juubei was around.
  • In episode 11 of Good Luck! Ninomiya-kun when told Mayu might die soon (she's a succubus so she needs life force) Reika's alternate personality tells Shungo she doesn't care since "it's more convenient for me if Mayu dies like this because then I can have you all to myself". She then agrees to let Mayu live so long as Shungo "becomes [hers] forever". This is also played with in regard to Shinobu, a maid of Reika's, who thinks Shungo is not worthy of Reika and is always trying to "execute" him.
  • In Haruhi Suzumiya, Haruhi is willing to destroy and rebuild the entire universe again with only her and Kyon if anyone gets too close to Kyon and she becomes jealous. Mikuru's closeness to him along with her boredom caused the first incident... without Haruhi even noticing that she had done so.
  • Honne-Onna of Hell Girl has diehard fangirls. One was ready to send someone to hell because she thought he was dating her. And another actually sent the other girl to hell because she thought she got too close to Onna.
  • A Zig-Zagged Trope in Hell Teacher Nube. Yukime was willing to kill her love rival, Ritsuko, but only after a very cruel Breaking Lecture from her father's lackey Ippon Datara, in which he first hit all of the girl's weak points and then told her that, if she wanted to become human and be able to be with Nube, she'd have to kill Ritsuko. So Yukime kidnaps Ritsuko and restrains her, apologizing all the way through said murder attempt... but she then decides that no, she can't kill someone who has done nothing wrong to her, and lets go of her. Which ends up with Yukime dying as she's tortured to death by Datara. (She gets better, however).
  • Hetalia: Axis Powers:
    • In one drama cd Belarus, already Yandere for her brother, is implied to be attempting to strangle a cat in one scene because it got in the way of her and Russia. She also does such things as scaring people away who Russia is trying to get close to and once breaks Lithuania's fingers because she's angry he has Russia's attention.
    • Russia considers doing this to America because he really wants to have friends and America keeps making friends with the people Russia wants to make friends with thus he's getting in his way.
  • Highschool of the Dead: Takashi believes he may have crossed the Moral Event Horizon after being forced to kill his recently-zombified best friend, Hisashi. Though it was to protect himself and Rei, Takashi admits that it was a little easier to Shoot the Dog out of jealousy because Rei had chosen Hisashi over him.
  • Hunter × Hunter: Shaiapouf is afraid Komugi might distract the King from his "true goal" and is therefore considering killing her for "the King's sake".
  • Ibitsu: The Strange Lolita's solution to the fact that Kazuki already has a younger sister is to personally make sure that Hikari is taken out of Kazuki's life... permanently.
  • Inuyasha:
    • When Koga first decides (completely unilaterally and over the course of about five seconds) that Kagome is "his woman." Upon realizing that Inuyasha is possibly in the way, Koga cheerfully proclaims that he will simply have Kagome by killing Inuyasha. He proclaims this to Kagome. He's blissfully unaware that she might have a problem with the idea. (He doesn't actually do it, of course, or even really try. But the logic is the same).
    • Onigumo/Naraku tries to kill Inu Yasha several times because of his "love" for Kikyou. Although it's a little iffy due to the majorly conflicting motivations between his human and youkai sides, which hate each other as well.
    • Kikyou once tries to murder Kagome because she is "in her way", and attempts to drag Inuyasha to Hell with her. She loosens up as her rage at the world diminishes and then she focuses on destroying Naraku for once and all.
  • Kaguya Hime: Mayu lets her mother die in front of her eyes for making both Akira model nude for her and coercing Akira into a same-sex relationship with her. She also threatens to kill anyone Akira gets involved with.
  • Kaguya considers doing this to Moeha in Kaguya-sama: Love Is War after discovering that she has a crush on Shirogane, but it quickly turns into a bonding moment between the two when it's revealed that all of Moeha's reasons for liking him match up with her own.
    The joy that comes from sharing the things you like about your first love is a miracle that eclipses all contempt for one's rival in love.
  • Karakuridouji Ultimo: Rune, Yamato's lover in a past life reincarnated as a man, threatens to do this to Yamato's crush Sayama if Yamato doesn't do as he says.
  • Subverted in Kenichi: The Mightiest Disciple with Shou Kanou, who is Kenichi's main rival during the D of D arc. Both of them are in love with Miu and want to prove themselves worthy of being the man who protects her, and while Shou fights Kenichi with the intent to kill and at one point even tries to kidnap Miu, he ends up accepting gracefully when Miu tells him up front that she already has someone who will protect her. He even ends up performing a Heroic Sacrifice to shield them from being shot by one of the Yami soldiers, and with his dying breath makes Kenichi promise he'll protect Miu. On top of that, we're shortly revealed that he only pretended to have killed Team Pankration so they could escape with their lives, hinting that, deep down, he didn't want to actually kill Kenichi.
  • In The Laughing Target, the protagonist has a cousin to whom he made a Childhood Marriage Promise. However, he eventually grew up, moved on, and started dating a girl at his school. When the cousin moves in with the protagonist (after her mother's mysterious death), it turns out that she hasn't moved on — and she's very unhappy with the new girlfriend for taking what's rightfully hers...
  • The grotesque huge Captain Continental lusts after Jonathan in Legend of the Blue Wolves. However, Jonathan rejects his amorous advances in favor of his growing feelings for Leonard. Captain Continental notices their growing closeness and does everything he can to separate them, including calling Jonathan to his office alone so he can try to make him sexually submit to him, and rushing at Leonard with the intent to beat him after he tries to stop Captain Continental from beating up Jonathan and trying to make him submit to him. He later attempts to have Leonard locked into solitary confinement in order to get him out of the way after framing Jonathan for being a spy. He and his subordinate then approach Jonathan before beating him and gang-raping him.
  • In The Legend of Zelda: Twilight Princess (2016), besides the threat Link poses to his rule, Zant wants to kill him for being close to Midna.
  • Manami Anzai from Life (2002), who first appears as a cute and childish clique leader who snaps utterly when she suspects Ayumu is trying to steal away her boyfriend. She goes so insane that she then dates a gang leader on the side to use him to get back at both Ayumu and her boyfriend, and then promptly screws her boyfriend and the gang leader both over. Not to mention her vow to kill Ayumu with her bare hands. Then she crosses into Cute and Psycho territory.
  • In Love, Chunibyo & Other Delusions!, Satone Kidnaps Rikka and makes Yuuta play a game with her where they have to break up if she wins.
  • Hiromasa of Love Pistols considers doing this in regards to anyone who expresses interest in Shima.
  • In Lovely Complex Mimi has a crush on Otani. She then learns that Otani is dating Koizumi and acts incredibly malicious towards her, including telling her with a Slasher Smile that she will make whatever is left of her life extremely painful if she gets any closer to Otani and trying to stab her hand with a pencil and getting angry when she misses. She later more or less mellows out though.
  • Nova in Magic Knight Rayearth wants Hikaru all to herself and won't hesitate to kill her friends in order to eliminate all competition.
  • Mirage of Blaze: Naoe does this by raping Kagetora's lover and later on forcing Kagetora to possess her to save his life.
  • In the second to the last episode of Mobile Suit Gundam 00, Andrei Smirnov, who is in love with Louise Halevy, attempts to do this to Saji Crossroad, Louise's long-distanced boyfriend, blaming him for her deteriorating condition. Luckily, Setsuna is there literally (their mechas anyway) just behind Saji to prevent it. He tried to do it directly, but failed.
    • A mildly-popular theory that was ultimately jossed by canon invoked this, via speculating that Billy Katagiri had caused the incident that led to the death of Emilio Ribisi, all to get close to Emilio's girlfriend Leesa aka Sumeragi. In truth, it was Sumeragi and Kati's own mistakes that brought said disaster; Billy did later show Yandere tendencies for her, but in this he had nothing to do.
  • And in Mobile Suit Gundam ZZ there's Beecha, who plotted with Mondo to have Judau killed by unknowingly using real bombs that the two lied were fake. This is due to Beecha's jealousy over Elle swooning over Judau and the feeling that he needed Judau out of the picture to make himself look like a better match for Elle. Fortunately, it fails.
    • A non-romantic (we really hope) version also occurs, with Puru briefly attempting to murder Leina Ashta, because she wants to be Judau's little sister and is well-aware that Judau cares for Leina more than he does her. Judau manages to talk her out of it by promising that all three of them could be a family together after the war was over.
  • Bonaparta does this in Monster in order to win the love of the twins' mother, whom he had kidnapped as part of a eugenics experiment. It is later revealed in Another Monster that the man he had set her up with as part of the experiment and then killed was his own brother, having already mind raped his father at a younger age for stealing the affections of someone else he had fallen in love with.
  • In My-HiME, Shiho Munakata is in love with her childhood friend Yuuichi Tate, who's in love with Mai Tokiha. When Shiho comes to believe that Mai is stealing Tate away from her (more due to Tate's actions than Mai's), she attacks Mai to keep her out of the way permanently, which isn't helped by Nagi preying on Shiho's insecurities later. The true tragedy is that, as Mai realizes in the fight, due to the mechanics of the whole Himelander thing going on, if either of them loses the fight (since Mai realizes she is beginning to develop feelings for him, as well), Tate will die. This doesn't stop Shiho, though, as she's gone over the deep end already, and Tate finally dies after Mikoto kills Shiho's Child.
  • Psycho Lesbian Tomoe from My-Otome wants Shizuru, and is perfectly willing to harm or kill anyone whom she perceives as a threat to her ultimate goal. This leads her to do nasty things to Arika, whose fangirl crush is seen as stealing away from any attention that might otherwise have gone to Tomoe. On top of that, Arika isn't even a real contender in this Love Triangle — that honor goes to Natsuki, Shizuru's boss.
  • Naruto:
  • In Negima! Magister Negi Magi, Tsukuyomi just wants Setsuna to herself and wonders if it's okay to kill her charge and girlfriend Konoka.
  • Neon Genesis Evangelion:
    • Naoko Akagi was sexually involved with Gendo Ikari after the death of his wife Yui Ikari, though it is suggested that Naoko wanted Gendo before, as she described Yui's disappearance as being exactly what she'd hoped for. Naoko still strangled the first Rei Ayanami when the child said that Gendo considered Naoko as an "old hag" and no longer useful (Rei's resemblance to Yui might also have been a factor, as Yui's face appears superimposed over Rei 1's as she speaks to Naoko). She was later horrified that she had done so and committed suicide.
    • Also, Ritsuko Akagi was romantically involved with Gendo, as her mother Naoko was before her. However, she eventually realizes that Gendo is using her in the same way that he used her mother and that he cares about Rei more than her, so she likens Rei to that of a romantic rival. In the manga her disdain of Rei is more evident: at one point, during one of Rei's medical checkups, Ritsuko loses control after Rei rebukes her and tries to strangle Rei to death. Realizing that she was acting like her mother before her, she stops herself from killing Rei but warns Rei against telling anyone what happened. She also destroys the Rei clones in a bid to get at Rei and Gendou.
  • Onii-Chan Control features Noa, the little sister to the main character, who revealed she's willing to stab a girl she thought was interested in her brother. Of course, she never shows that side of her whenever her brother is around.
  • Outlaw Star: Harry attempts to get rid of Gene in episode 21, once he realizes Melifina was in love with him. And tried to do the same to Hazanko for coming between them at the Galactic Leyline. Neither attempt ends well for Harry, especially the latter.
  • PandoraHearts: Gil's devotion to Oz has a pretty dark edge. Hinted early in; outright shown in chapter 33, where Vincent goads him into saying/resolving to kill anyone who hurts or snatches his master away from him — no matter who it is. He almost went through with this concerning Alice. Luckily, he stops himself in time and thankfully, Alice didn't notice a thing.
  • Paprika: Osanai tries to strangle Konakawa in his dream when the latter tries to take Chiba, whom Osanai loves, away from him.
  • Peacemaker Kurogane: In the manga, Suzu comes to this conclusion when Ryoma decides to take Tetsunosuke away from him. Some fans also theorize this is what Suzu has in mind when he pays Saya, Tetsunosuke's love interest, a surprise visit, given his obsession with Tetsu.
    • Yoshida, Suzu's master, also qualifies as it's implied he was jealous of Suzu's close friendship with Tetsu and many times tried to have Tetsu killed because he had feelings for his charge Suzu. He did this by trying to manipulate Suzu into doing so and then trying to do so himself out of frustration when that failed. He refused to give up in this endeavor even after having his arm cut off and held a sword in his mouth to Tetsu's throat. Only him suddenly being decapitated by Okita stopped him.
  • Peach Girl:
    • Sae hates Misao for being the one Ryo loves since she loves him herself and, at one point, tried to push her into the path of a moving bus. However, Kairi restrained her at the last second so she wasn't able to.
    • Kairi's trio of Clingy Jealous Girls absolutely hate Momo for winning Kairi's affections. They make a habit out of harassing/threatening her, once deliberately made sure she got separated from Kairi and was stranded during a class trip, push her into the path of a campfire when she was holding cooking oil, and, at one point, held her down, and told her that she has to sign a contract swearing that she'll stay away from Kairi or they'll burn all her hair off (while holding a lighter to her hair), and try to beat her up later on when she states that their selfish and cruel actions won't make Kairi fall in love with them, and when she tells them that her love for Kairi is genuine. In addition, they take the threat even further with "We'll burn your face so badly that Kairi won't ever look at you again," and "Don't worry, we'll push you into the pool before your whole body catches fire."
  • Penguindrum: It's implied that Tsubasa stabbed Tabuki out of jealousy once Yuri broke off their affair.
  • Played for Laughs in episode 5 of The Pet Girl of Sakurasou, Sorata and Mashiro have a talk after Nanami agrees to move into Sakura Hall. Only Sane Man Sorata's plan is to bribe Mashiro with food with a promise that she would take care of herself. Jin the Casanova suggests they tell Nanami they're dating, which Sorata immediately rejects. Innocently Insensitive Idiot Savant Mashiro then innocently invokes this trope by stating that she should kill Nanami to keep their secret safe, which he also immediately dismisses. Sorata decides to try his idea, which he calls Plan A, calls Jin's idea Plan B, and Mashiro suggests her idea is Plan C, causing Jin to start laughing wildly at Sorata.
  • Sayaka Kouno of Princess Princess once shoved one of Tooru's previous girlfriends down a flight of steps out of jealousy. And then there's her habit of stabbing Tohru's girlfriends with scissors.
  • Ranma ½ makes good use of this trope, given its base is a mixture of Arrogant Kung-Fu Guy and Love Dodecahedron. Fanon, however, tends to greatly exaggerate it for various characters who have used it or hold similar attitudes.
    • Tatewaki Kuno: Has never actually tried to kill Ranma for Akane or "the pigtailed girl's" hand, and doesn't even seem to want to kill Ranma in their fights. His attitude of "if I beat up Ranma, then the girls I want will naturally flock to me for proving my studliness" does fit under the general umbrella of this trope, but lethal force is not his intention. Though... there is the way he starts swinging around a live steel katana instead of his bokken during the Tanabata and Failed Wedding stories, which probably inspired his fanon reputation.
    • Kodachi Kuno: Joined in with Ukyo and Shampoo in attacking Nabiki during the "Nabiki, Ranma's New Fiancee" manga arc, in hopes of killing her and taking him for herself. Similarly, teamed up with them to beat up Miss Hinako during the manga arc she was introduced in, as she suspected the teacher was trying to seduce Ranma. She did show at the Failed Wedding in a wedding gown of her own and planning to marry Ranma herself, but wasn't slinging bombs around like Ukyo and Shampoo.
    • Ukyo Kuonji: Generally prefers more "nonviolent" approaches to trying to win Ranma, such as setting Akane up on a date with Ryoga, trying to lure Ranma & Akane into a magical Kimodameshi that will supposedly break them up irrevocably, or agreeing to let Ranma stay at her home after he is kicked out (and, later, to let him use her business as a wager on the condition he will join her in resuming her travels if he loses it) in hopes that this will make him "realise how perfect she is for him". However, she can go about it violently as well; she willingly joins in with Shampoo and Kodachi when they attack Nabiki with plans to kill her and then fight over who gets Ranma, and is the one who suggests Hinako might be trying to seduce Ranma and leads the other two girls in ambushes on her. She shows up at the Failed Wedding throwing bombs, though possibly at Ranma rather than Akane, and wonders why she didn't think of it herself when Kodachi reveals her plan to use this ceremony as a way to marry Ranma at last. In the anime, though the aforementioned attacks on Nabiki and Hinako are removed, Ukyo plots to herself about killing Akane when she asks for her help in the second of the "One to Carry On" filler OAVs and begins throwing random heavy objects at her, growing angry when Shampoo throws something at her and leaving a clear impression she thought that she and Shampoo would work together to kill Akane, and then finish fighting each other.
    • Shampoo: Given she stated "obstacles are for killing" when Ranma tried to prevent her from attacking Akane for Ranma's hand in her first story, it's understandable that she gets hit with this trope the most — in canon and in fanon. Fanon usually overstates her actually trying to kill her rivals, though. Canonically, while the idea doesn't seem to bother her in the slightest, it isn't something she tries all of the time. Notably, when she first thought Akane was an obstacle to pursuing Ranma's hand, she actually just wiped her memories of Ranma. Then, when it looked like Akane might be breaking through the memory block, she tried to strengthen the block, only attacking after Akane did break through the block and kept interfering — and even then, she stopped attacking Akane the moment Ranma told her not to. After that, though, she tried to give Akane a Jusenkyo Duck curse in order to "pawn" Mousse off on her, plotted to murder Akane and pin the blame on Taro in the first Pantyhose Taro story, was the first to suggest attacking Nabiki during her stint as Ranma's fiancee in the manga, joined in Ukyo's plot to beat up Hinako in the manga, came up with the same plan as Ukyo in "The One To Carry On, Part 2" and wrecked the plan by attacking Ukyo first instead of Akane... the final manga story arcs, Jusendo and the Failed Wedding, had a Brainwashed Shampoo (who, given she was obediently sent to murder Ranma, even if she did muster some Villainous Willpower to try and wriggle out of obeying, was arguably Brainwashed and Crazy) threaten to pop off the dollified Akane's head and a normal Shampoo attacked Akane & Ranma with bombs at the wedding ceremony.
    • Mousse: Introduced to the series specifically challenging Ranma for the right to Shampoo's hand, threatening to take Akane if Ranma couldn't beat him. On his return, attempted to murder Ranma by using him/her as the target in a knife-throwing act (Ranma managed to catch the knives in her teeth) and then chased him around the circus throwing daggers and water balloons full of Jusenkyo Duck water at him. Shortly after that, he kidnapped Akane and threatened to douse her with said Jusenkyo water, in reality planning to either murder or curse (whichever came first) Ranma when he raced to Akane's rescue. He then challenged Ranma to yet another duel to win a date with Shampoo. Repeatedly throughout the series, Mousse challenges Ranma to fights because, like Kuno, he thinks that beating Ranma will make Shampoo fall in love with him — unlike Kuno, Mousse doesn't seem bothered by the idea of killing Ranma if that's what it takes to win, though he has never actually "won" except in fights where he had other things on his mind and so passed over the opportunity to deliver the coup de grace.
  • Jegan fakes this in Rave Master. He kills everyone but the other two members of the love triangle (since he happens to be friends with the guy his crush liked more) then convinces each of him that he killed the other.
  • Reborn! (2004):
    • Lethal Chef Bianchi goes into a homicidal rage whenever she sees adult Lambo who looks exactly like her deceased ex-boyfriend Romeo, who apparently died of food poisoning. She also has an unrequited crush on Reborn and is perfectly willing to eliminate anybody who has a 'bad influence' on him.
    • Earlier on, Haru also had a thing for the younger, "angel-like" version of Reborn, to the point where she even tried to destroy Tsuna in order to free Reborn from his influence. She later gives up on her crush on Reborn and falls for Tsuna after he saves her from drowning.
    • In chapter 271 M.M. threatens to do this to Chrome. Chrome is on her way to deliver something to Mukuro and she encounters M.M. As soon as M.M. glances at Chrome she grabs her and yells at her before hitting her so hard that she falls to the ground, her mouth and nose bleeding. She then keeps calling her an "ugly bitch" and tells her: "The Mukuro-chan of this generation is mine! If you put your nasty little hands on him, I'll kill you!"
  • Rebuild World: A multi-layered example, with two of the aggressive parties having other motivations mixed in. Tiol and Katsuya trying to kill Akira, Tiol out of Amnesiac Resonance jealousy, and Katsuya to "free Sheryl" from Akira (having been lied to Sheryl is being blackmailed), Tiol trying to kill Katsuya over Sheryl as well. Akira is just left reacting to their unhinged behavior. With Tiol, it's mixed with Resurrection Revenge for Akira having killed his original body. With Katsuya, he's long been The Resenter of Akira over many things and the inciting incident is a Frame-Up Tiol set up to make it look like Akira just killed Katsuya's friends. During their three-way gun battle, the girl in question doesn't come up, however, there was an incident between two over the girl not long prior.
  • Revolutionary Girl Utena:
    • Nanami does exactly this to a kitten when her brother pays more attention to it than her, and she was the one who got him the kitten for his birthday in the first place. She also knows her brother is interested in Utena and actively tries to kill Utena during a duel with her. Also, when her once follower tries to get close to Touga she hits her and beats up her and her other two followers for going against her and trying to take Touga away from her.
    • In one episode, Miki's piano teacher is hinted to have a less than savoury interest in him, and he's inappropriately touchy-feely with him when they talk. Miki's twin sister Kozue has clearly noticed, as it later turns out that she'd previously shoved the teacher down the stairs for it.
  • Mizore in Rosario + Vampire tries to kill the rest of Tsukune's harem and turn Tsukune himself into a popsicle so she can have him all for herself. However, once she's added to the harem she becomes friends with her love rivals and continues to stalk Tsukune. She says herself that she doesn't really "need" to stalk him anymore; it's just "more fun."
    • In chapter 52 of manga season II Akuha is revealed to be a Yandere for Moka. She attacks Kurumu and Mizore saying that she will kill anyone who tries to take Moka from her.
    • In chapter 53 she announces her intentions to kill Tsukune after learning he and Moka are together.
  • This is often the path villains take in Sailor Moon:
    • Beryl, Ann, and Black Lady try to kill Usagi to get Mamoru, while Al and Diamond try to kill Mamoru to get Usagi. Emerald also tries to do in Usagi to win Diamond.
    • Fiore in the R movie tries to kill Usagi both because she is Sailor Moon and out of jealousy over Mamoru, whom he is attached to because of how kind he was to him when they were kids. He gives up on it by the end and even sacrifices his Life Energy to revive Usagi when she dies saving the earth.
    • Also invoked by Al and Ann from the Makaiju Filler Arc, especially in the end when Al orders the tree to kill Mamoru so he can have Usagi, then Ann retorts by ordering it to kill Usagi so she can have Mamoru. This sends the Makaiju into a Villainous Breakdown. It all gets better in the end, though, and Al and Ann leave Earth together and free of their Yandereness.
  • Sakura Gari: Sakurako and Katsuragi both try to do something of the sort to Masataka in order to have Souma for themselves. And Sakurako spends a good amount of her time trying to drive away any person that Souma gets involved with via torturing them into insanity, i.e, she causes a pregnant servant girl to lose the baby of Souma's that she was pregnant with. (Or in the case of the artist Terashima, breaking his drawing hand and then pushing him down a flight of stairs.). And some of the people that Souma took as lovers in the past tried to do this when he tried to get them to leave him alone. One of them, Yoshino, tried to stab Souma in the streets, and when refused he was Spurned into Suicide.
  • School Days:
    • The ending to the anime, where Kotonoha violently Murders The Hypotenuse, right after the Hypotenuse, Sekai, murders the lead, Makoto, thus killing the triangle.
    • This was reversed in the manga, where Kotonoha is the Hypotenuse that ends up killed after trying to kill Sekai.
  • Shattered Angels: Resident Psycho Lesbian Mika Ayanokoji tries to sacrifice the hypotenuse. Ultimately it's cut short before anyone's sacrificed but is ironically turned around when Mika is killed off rather nicely.
  • Shiki has Megumi who after turning into a vampire murders her crush's best friend because she's jealous of how close they are.
  • SHUFFLE!: Kaede snaps in episode 19 upon seeing Rin bring home Asa, whom he's dating. She screams at Asa to get out and viciously attacks her.

She gets better, though.
  • Gopher of Soul Eater beats Kid to a bloody pulp twice for having Noah's attention and got extremely pissed off when Maka turned out to have the same uniqueness that made Noah have apparently fleeting interest in Gopher.

With his chance of killing Maka gone, Gopher beats up Kid some more until realising that while hitting him doesn't achieve anything, showing him something asymmetrical does. He exploits this until Noah turns up and takes Kid away.
  • Played with in Speed Grapher. Dark Action Girl Ginza is desperately in love with her friend Saiga, admits to be really jealous of his protegée Kagura (and once returns her to her mother, the one Saiga is trying to free her from) and does admit out loud that she'd love to kill her... but in the end, she decides to protect Kasgura with her life, since Saiga made her promise that she'd protect Kagura.
  • Street Fighter II: The Animated Movie: Vega's portrayal here was a large part of the reason that gamers thought he was gay until Capcom set the record straight years later. When he sees M. Bison perving on a live video feed of Chun Li, Vega visibly becomes jealous. Which doesn't go unnoticed, so Bison gives him the order to kill her. Vega accepted without a moment's hesitation... except she kicks his ass out of her apartment. Literally.
  • Tayutama has a minor case with quasi-tsundere Ameri, the Unlucky Childhood Friend of the main character. As Ameri watches Mashiro slowly win Yuuri's heart, she decides (with no small amount of influence from the Dragon) that Yuuri shouldn't have to risk his life with all this magical nonsense. She concludes that the only way to keep Yuuri safe is to drive Mashiro away... with a little help from the villain. In case you didn't realize this a bad call, she gets bat wings, Dull Eyes of Unhappiness, and a dark purple aura.
  • Tenchi Muyo! plays it for laughs. Ayeka and Ryoko are involved constantly in this with each other, while their power levels makes it closer to Wile E. Coyote vs. Wile E. Coyote. In Tenchi Universe, it's played more seriously: Ryoko tries to convince Tenchi to abandon a kidnapped Ayeka to Kagato, possibly to invoke the trope, but when Tenchi chooses otherwise she decides to support him anyway.
  • Threads of Time: Sali Tayi comes to this conclusion very quickly when he discovers that Atan Hadas likes Moon-Bin.
  • In Tokyo Ghoul:Re, there's plenty of this to go around.

When Tsukiyama asks him to buy some time, because the Quinx keep getting in the way of a private conversation.....Kanae hires several members of Aogiri to help him try to kill them. Afterwards, Eto corners him and forces him to realize that what he really wants is to have Tsukiyama completely under his control and make Sasaki suffer as much as possible before killing him. Things quickly escalate from there, and he seems genuinely convinced if he can just murder his rival, he'll win the heart of his beloved master. Their rooftop battle is a carnage-filled No-Holds-Barred Beatdown, with Kanae screaming that he's finally going to be loved. Instead, she ends up making a Dying Declaration of Love before sacrificing her life to save Tsukiyama and dies content.
    • Mutsuki harbors secret feelings for Haise Sasaki, and becomes aware of his crush on Touka. After suffering major Sanity Slippage, Mutsuki's jealousy escalates to murderous obsession. Urie discovers Mutsuki's bedroom is a Room Full of Crazy, with dozens of copied photos of Touka pinned to the wall by knives. And then Mutsuki shows up at :Re and violently attacks Touka, before showing her a mangled hand that allegedly belongs to her old friend, Yoriko. Mutsuki even explicitly tells Kaneki while sporting a deranged Nightmare Face that he wants him to come back to him and will kill anyone who gets in the way.
    • In the first manga, Tsukiyama is obsessed with and wants to eat Kaneki so he goes into a rage when he sees Touka take a bite out of Kaneki's shoulder and tries to kill her.

  • Kish from Tokyo Mew Mew is a stalker who constantly attempts to get rid of Ichigo's boyfriend Masaya. He even attempts to kill Ichigo herself if she refuses to become "his".
  • In the Trigun manga, this turns out to have been over half the point of the entire Gung-Ho Guns plotline. Legato was jealous of Vash. Because Knives was preoccupied with his twin, the only person on the planet he didn't intend to kill, and Legato apparently felt that if Knives had no one living to care about, he might find some scrap of affection for his chief minion. And Knives breaks his spine when he finds out.
  • In the yaoi manga Under Grand Hotel, in the first few scenes we see Lain Brody in, he gives Sen a blowjob, strips him, drugs him, and outright molests him as he's drugged (including telling him "No way in hell am I letting Sword Fish kill you. Because he doesn't love you. I'm the only one that can kill you."), rapes him with a mop handle, ties him up, and hides him in a dryer. And when Swordfish finds Sen, he gives him CPR. Lain responds to this by stabbing Fish in the arm with a fork and tries to stab him again while screaming, "Get off of Sen! He belongs to me!" Immediately after that, Lain is shot and killed by security guards.
    • Also, Swordfish threatens anyone who expresses an interest in Sen with death, kills the guys who raped Sen saying that he did it for Sen's sake even after Sen told him not to kill them, moves out of Sen's room, and lets a rapist move in when angry with Sen, and slices the throat of another one of Sen's rapists right in front of him while saying "I love you, Sen." This being after he tried to get Sen to kill the guy himself but Sen refused.
    • And Norman's in love with Swordfish but pretended to be in love with Sen so he could get closer to Swordfish. He tried to persuade Swordfish to kill Sen but that didn't work. So, on one occasion when there was a scuffle going on he tried to get Sen out of the way by stabbing him with a pencil but accidentally ends up stabbing his inmate Walter instead who was trying to protect Sen in the hope of getting protection from Swordfish. When he finds this out, Norman holds a knife to Walter's neck telling him, "If you don't want to die, don't butt in again Walter!"

  • Wolf Guy - Wolfen Crest:
    • Haguro (who's Yandere for Inugami's werewolf form) does not take it well when Chiba briefly meets up with Inugami. At all.
    • Possibly Ryuuko Konuma's motivation for selling out Aoshika to Haguro beside, you know, avoiding another beating. Heaven help Aoshika. Given the eighteen chapter gang rape, heaven's a little late. After that, Haguro also tries to kill Aoshika while telling her that Inugami is too good for her. Fortunately, Inugami shows up in time.
  • Yuri Kuma Arashi: Mitsuko kills/eats Sumika, Kureha's girlfriend, purely because she desires Kureha.

In the second, the husband is ignorant of the affair, and the friend takes advantage of an innocent invitation up to the forest cabin to get the wife for himself once and for all. As predictable in EC comics, neither plot ends well for the perpetrator.

After going through a massacre (Finding that it's not easy when you're overweight) he eventually manages to complete his mission. He then cuts off the guy's dick and sticks in his girl's mouth, telling her "Fuck off and die, bitch." Quite a memorable ending, and squicky at that.
  • During the "Return of the King" storyline in Ultimate X-Men, after Cyclops goes missing on a mission to the Savage Land with Wolverine, rumors start floating around that Wolverine killed Cyclops so he could be with Jean Grey. But it turns out that the rumors are, in fact, completely true. This comes as a special surprise if you're used to the main universe's Wolverine, who goes by samurai honor codes and such.
  • X-Man: Nate's very strange relationship history included Threnody (who was looking to use him both to sate her hunger for death energy, since he was dying and immensely powerful, and to deal with Sinister for her), and Maddie Pryor (clone of his biological mother, who he accidentally resurrected as a psychic ghost and had a lot of UST with before he found who they were to each other, and generally acted as a textbook Tsundere to the bewildered Nate). The two met and Maddie went on about "needing him" — though mainly to stay alive. Threnody wryly commiserated with her... then made the mistake of not only noticing that Maddie wasn't quite alive, but stating it. Maddie promptly murdered her, before going to find Nate. Threnody didn't exactly stay dead, but that's another matter.

While technically she destroyed the piano both times, it didn't help; Schroeder just got a new one each time. (And the second time, threatened to slug her if she "scratched it with her stupid elbows".) It would seem that the piano was not the problem at all (as anyone who knows Lucy can surmise.)

Rhaenyra was already paranoid about the dragonseeds since two of them had already betrayed her. This pushed her over the edge and she demanded that Lord Manfryd Mooton, Nettles' and Daemons' host at the time, execute Nettles and deliver her head to Rhaenyra.

It isn't really clear if Snape is hoping at first that by doing this he will get a chance to woo Lily, or if he simply wants to save her life. What is clear is that having his hated enemy killed is less important to him than saving the only love of his life. Events develop to make the point moot.

Esmeralda, understandably, is less than impressed and refuses to go along with him.

So Mura hatches a scheme to poison Azhar using some E. Coli he procured from a friend in his wine — and problem #1 is that Azhar is a devout Muslim who doesn't drink and passes on it when offered. Problem #2 is that Angelina drinks some instead, despite Mura's outburst, in front of a news crew no less, that she shouldn't, but no one there thinks twice about it since she's pregnant and they figure that's why he's acting like that. Then Angelina gets sick and ultimately dies from the E. Coli, so Mura not only failed to kill his love rival but also killed his lover and unborn child in the process. Sucks to be him.

  • In the Ben Bova novel Mercury, the story starts with Mance Bracknell, lead engineer on a space elevator, married to Lara Tierney. Victor Molina, the astrobiologist best friend of Mance, wants Lara. When the space elevator collapses, killing hundreds of millions of people and devastating many nations, Victor falsely testifies in court that Mance was negligently responsible for the collapse, getting him put into forced labour for life. After an accident wipes out everyone on a spaceship but him, Mance takes on the identity of one of the crewmembers and (eventually) gets a job as manager of a colony on Mercury. He lures Victor (who is now happily married to Lara) to Mercury with some life-bearing rocks he's planted, with the goal of getting Victor publicly humiliated when his astrobiologist peers inevitably discover that the rocks aren't from Mercury (thus showing him as either a fraud or an idiot, either way ending his career). Mance seems to think this will get Lara back, but when he reveals his identity, plan, and Victor's false testimony, Lara rejects them both. Smart woman.
  • Mistborn contains an unintentional example— or arguably two. Vin kills Elend's ex-fiancee, Shan Elariel, who was attempting to kill Elend at the time, and later Zane in a triangle where she's Alice. Actually, that particular romance advances via death four times.
  • In Andrei Belyanin's My Wife Is a Witch, the protagonist Sergey is a poet, who finds out that his wife is a powerful witch, who goes to the "dark worlds" every full moon in the shape of a wolf.

Fortunately, Sergey finds out that, while in the "dark worlds", his poetry turns into powerful spells, making him a sorcerer. Of course, Sergey's wife has no intention of leaving her husband for the werewolf, but Owl couldn't care less, planning on casting a Mind Control spell on her.

  • Peter Pan:
    • Tinkerbell did not by any means like Wendy, she even tried to kill her. All because Peter paid more attention to her than Tink. Most adaptations keep the general clinginess but tone it down from "homicidal fury." This also occurs in the film adaptations.
    • The mermaids were precious little better, but, then again, they don't seem to like anyone in the book (The Peter Pan Disney mermaids... well, they aren't much better than Tink. They do take particular distaste in Wendy whatever the version and try and drown her.)
  • In Gaston Leroux's The Phantom of the Opera, the narrator speculates that the mysterious figure Raoul shot on his balcony really was Erik coming to kill him, but circumstances forced him to change tactics.

  • In Ruslan and Ludmila, Ruslan's villainous rivals are eager to get him out of the way in order to win Ludmila over. Rogday attempts it, only to be killed by Ruslan himself. Farlaf succeeds in it (while Ruslan is asleep), but Finn comes to the rescue and resurrects Ruslan.

  • In The Shattered Kingdoms, In the second book, Vrinna (who loves the emperor) attacks Kira (the emperor's mistress).

It didn't work - instead of falling in love with Zara, Caleb fled Winter Harbor to escape from her.
  • In Robert E. Howard's "The Slithering Shadow", because Conan the Barbarian is too loyal to his slave girl Natala to be seduced by Thalis, Thalis abducts Natala, intending to have her killed.
  • A Song of Ice and Fire:
    • It's implied that Littlefinger had this in mind for Eddard so he could steal his wife Catelyn. Mind you, he was probably aiming for 'disgrace and permanent exile' and not actual death: When Joffrey actually decides he wanted Eddard dead, that probably ruined Littlefinger's plan, but the man's actual intentions are still unclear so for all we know he wanted it to happen.
    • A more complex case comes up later on; Quentyn Martell arrives at Meereen to act on a marriage pact he has with Daenerys Targaryen, which she herself is completely ignorant of, but finds her already married to the local Hizdahr. When poisoned food is served to Hizdahr and he offered it up to Daenerys, it's not clear which of the two was the actual target, and there is some suspicion that Quentyn himself tried to poison Hizdahr for this very purpose. Sort of a moot point, because Daenerys had no interest in either one of them, and only married Hizdahr for political reasons.
  • The Sorrows of Young Werther plays with this trope a bit — Werther considers playing it straight and killing Albert, realizes he can't, and then inverts it by killing himself instead.

He had also gifted her a very expensive ring that had belonged to the wife. Her method was to be a faulty hairdryer that the salon's janitor had rigged up to serve as an electric chair. So the day of the murder, the stylist places the wife underneath the dryer and ends up dying herself. It turns out the expensive ring that the boyfriend gifted to her had a curse on it and in wearing the ring while placing her under the dryer, it acted as a metal rod that had her take all of the electricity for herself, leaving the wife horrified but unharmed as she lept out of the chair once the electrocution started.

  • CSI: NY: The killer in "Criminal Justice" planted a cigarette lighter at a murder scene in order to frame his wife's lover and get rid of him.

The woman had a pattern of getting married, meeting another man, convincing the other man to kill her current husband, marrying the other man, then meeting another man...What made the plan nearly foolproof was that the other man usually did all of the killing, and then the next man would kill that guy, so that there was virtually no proof of the previous crime.

    • This was the solution of Ryutaros in Kamen Rider Den-O, with the hypotenuse being Yuto Sakurai/Kamen Rider Zeronos, believing that doing so will win Airi's heartnote . Of course, given the type of series Den-O is, it's Played for Laughs, and he fortunately never actually carries the deed out.
    • Kamen Rider 555 gave us Masato Kusaka, who had an obsessive one-sided crush on his childhood friend Mari Sonodanote  and would smoulder and plot the murder of anyone he thought was trying to court her, particularly the main character Takumi Inui.

This trope is used not once, but twice on the show. Dean Moriarty seems to be the go-to target (or romantic rival) for Alex's other boyfriends when it comes to this trope, because he's the hypotenuse in two different occasions, suffering great examples from two different romantic rivals.
  • In the sixth episode of season two, Alex's disconnection from her handsome boyfriend Dean Moriarty coincides with the arrival of evil blonde Ronald Longcap Jr., a wizard student who immediately sets his eyes on Alex and is very unpleased in learning that she already has a boyfriend. Upon meeting Dean for the first time, Ronald leads the boy into the kitchen and in order to get him out of the way of his plans with Alex, uses a spell that traps Dean inside a huge cube of jelly, frozing him in time with an anguish expression. Ronald then uses a spell to turn into Dean and heads over Alex's where, under the guise of Alex's boyfriend Dean, breaks up with her so that she can be with him once she meets him as Ronald. His plans briefly works as the episode ends with Alex confessing she likes him and accepting to return to Wiz Tech with Ronald. The episode ends with a shot of Dean still trapped inside the huge cube of jelly.
  • Season 4, Episode 4. This time Alex and her boyfriend Mason Greyback are going through a pause on their romantic relantionship and decided to remain good friends when Dean Moriarty returns, straightfowardly making it very clear that he wants him and Alex to be boyfriend and girlfriend again as soon as he walks in. Mason is immediately jealous, and although Alex tells Dean that she has no intention on being his girlfriend again, Dean won't stop trying to win her back and the two of them start spending a lot of time together reminiscing their romance. As a werewolf, Mason can't control himself and halfway through the episode is revealed that he literally ate Dean, and that Alex's brother helped him with a spell to shrink Dean so that he would be easily swallowed. Way to get rid of your romantic rival!

  • This happens sort of incidentally in volume 16 of Ciel ~The Last Autumn Story~. Lariatte was Krohiten's main competition for being Yvienne's most important person, but the actual reason he helped orchestrate Lari's death was to use Yvienne's response to her death as part of a plan to prevent the predicted extinction of mankind. And the death wrecks their relationship anyway.

    Mythology and Religion 
  • In Arthurian Legend, some versions have King Mark do this when he finally finds evidence of Tristam's affair with Isolde. He also kills Isolde. Others avert it by having him merely exile Tristram, who later dies of other causes (and then Isolde dies of a broken heart).
  • The story of King David and Bathsheba in The Bible (2 Samuel 10-12), where the king sends a general named Uriah on a suicide mission because he fancies Uriah's wife (to the point of actually sleeping with her in the actual Bible accounts; the Bowdlerized versions never mention that), makes this Older Than Feudalism. He paid for it. Oh, did he pay for it. When God actually calls you out and then the first child you have with your now-wife dies....
  • In Classical Mythology, this is one of the causes of death for Achilles' son Neoptolemus. Due to some shenanigans, Hermione (daughter of Helen and Menelaus) ends up promised to both Orestes and Pyrrhus. She is eventually married to Pyrrhus but Orestes doesn't take it well and kills Neoptolemus to claim his cousin for himself.

  • Hurt:
    • The POV character of "Got Jealous" is a Crazy Jealous Guy on the run after attacking his obsession's new flame.
    • A woman threatens False Rape Accusation to coerce her lover into this in "Pandora" (though it's implied to be more about her husband's life insurance than love.)
  • The singer of Jayn's "Smoke And Mirrors" repeatedly suggests she will kill her crushes wife if he doesn't tell her he loves her, and her alone. The ending heavily implies she did it anyway.
  • In "Hide Your Heart" by KISS Rosa and Johnny fall in love. The problem is, Tito happens to be dating Rosa, and he is furious that he is being replaced. Johnny gets shot by Tito.

  • In Nicki Minaj's "Your Love", her romantic rival is jealous that she gets all the attention from the dojo master, and so the two women end up in a sword duel that results in Nicki's character's death.
  • "Jenny Again", by Tunng. The titular Jenny is the equivalent of the example's Alice: the listener is put into the position of Bob, and the singer is in the position of Chris.
  • The point of view character for Ex-Lover's Lover by Voltaire dreams of doing this, but at the end admits he would never have the guts to go through with it.

  • Sick Sad World: "Killer Couples" has a case of a couple murdering their teenage roommate because they thought she flirted with one of them.

    Tabletop Games 
  • In the far-flung history of the the Clans in BattleTech, Khan Ellie Kinnison of Clan Steel Viper was obsessively in love with the Clans' supreme leader, Ilkhan Nicholas Kerensky. However, Kerensky was married to Jennifer Winson of Clan Wolf. Kinnison had the brilliant idea of trying to murder Winson so that a grieving Kerensky would turn to her for solace. Only timely intervention of Kinnison's saKhan Steven Breen spoiled the plot. Trying to assassinate Winson while she was traveling with Kerensky probably didn't help her case either. Kinnison was killed in the attempt on Winson's life by Breen who shot her and received a Klingon Promotion.
  • Happens in the continuing example game in Bliss Stage, prompted by Josh asking Keenan what he thought of the love interest Sara. His response: "Man, she's getting all girly and clingy and poop. Lousy lay, too."
  • In probably the definitive Act of Ultimate Darkness from Ravenloft, Count Strahd Von Zarovich murdered his brother Sergei, who was set to marry Tatyana, the woman both men loved, on their wedding day, making him the setting's first and most definitive Darklord.

  • In a subversion, in Avenue Q, after Princeton breaks up with Kate and later gets together with The Vamp Lucy the Slut, Kate angrily throws the lucky penny Princeton gave her off the Empire State Building, hitting Lucy, breaking her neck, and putting her into a coma. Oops.
    Princeton: Can you believe it? Some idiot dropped a penny off the Empire State Building.
    Kate: [unconvincingly] Shit.
  • Attempted in The Crucible. Abigail Williams is in love with John Proctor and tries to get Proctor's wife Elizabeth hanged as a witch. Due to a bit of Deus ex Machina, she not only fails (Elizabeth is pregnant and can't be executed), but she also gets Proctor himself hanged instead as he chooses to take the heat. Oopsie.
  • In Little Shop of Horrors, Seymour almost does this with Audrey's boyfriend Orin. He loses his nerve, but Orin dies immediately afterward through his abuse of his laughing gas and Seymour's inaction. Of course, this is less because he's dating Audrey and more because he's abusing her. When Mr. Mushnik figures out that Seymour did it, he assumes it's a straightforward case of this trope, but is Right for the Wrong Reasons.
    • Arguably, Audrey II him/her/itself attempts this when it tries to off the original Audrey, depending on how you interpret the plant's relationship with Seymour.
  • Medea: The original Woman Scorned, she killed her husband Jason's new fiancée after being dumped for her. This wasn't an attempt to win him back, however, but pure and simple revenge, particularly when she also put her children by Jason to the sword just to make him suffer all the more.
  • Andrew Lloyd Webber's adaptation of The Phantom of the Opera also has Erik threatening to murder Raoul if Christine refuses to submit to him.
  • In Sweeney Todd: The Demon Barber of Fleet Street, Judge Turpin fancies Benjamin Barker's wife, and has him convicted of a crime he didn't commit and shipped off to Australia just to get him out of the way. However, as in The Crooked Man example above, he escapes from prison and returns to get his revenge on the judge.
    • Arguably, Mrs. Lovett, with Sweeney and Lucy. She doesn't really do anything to Lucy, but still, she leads him to believe she's dead, just so she can have Sweeney all to herself.
  • Averted in the William Shakespeare play The Two Noble Kinsmen. Arcite dies of an unrelated injury after the duel against Palamon that he won.
  • Double subverted in The Women of Trachis. Lichas is reluctant to tell Deianira that her husband Herakles is madly in love with Iole for fear she'll become hysteric and do something drastic. Deianira actually just pities the girl and understands that Love Hurts even for Herakles. However, not comfortable with the thought that having Iole in the house will compromise her family, she decides to use a love potion on Herakles to get his affections back, which is actually a poison that kills him.

    Video Games 
  • Inverted in one quest in Arcanum: Of Steamworks & Magick Obscura: Wrath, an insane wizard, is envious of Sharpe the apothecary for his happy relationship with Ivory, but also believes in the adage that elves do not kill each other. So he instead commits suicide with a glass of poisoned wine in the hope that Sharpe will be blamed for his murder.
  • Attempted by Marco Barbarigo in Assassin's Creed II, when he pays thugs to kill Dante Moro, Captain of the Guard, so that he can marry Dante's wife Carlotta. In a variation, Dante survives, but is left severely brain-damaged and extremely impressionable, which allows Marco to talk him into annulling the marriage.
  • A double disturbing example in Assassin's Creed: Brotherhood comes from both Cesare and Lucrezia Borgia, brother and sister in an incestuous relationship. Lucrezia brutally beats Caterina, who is their prisoner, because she believes Caterina attempted to seduce her brother during the long carriage ride to their home (which she didn't). Lucrezia, however, is in a relationship with an actor simply to make Cesare jealous, so he orders his men to kill said actor.
  • In Baldur's Gate II, NPC Aerie can be romanced by both the player character and fellow NPC Haer'Dalis. If she chooses you, he'll back down, but if her romances with both proceed at about the same pace, he tries to settle things in this manner.
    • It can also happen if you keep Viconia, Jaheira, and Aerie in the party at the same time and don't break off the romance with any of them.
  • In Belladonna this occurs twice in the same triangle, thanks to reanimation.
  • Invoked and ultimately averted in BlazBlue, when Hazama uses Tsubaki's Clingy Jealous Girl tendencies over Jin and amps them up. She then sets out to kill her best friend Noel upon the belief that she's stolen her rightful place next to him. But even then, once Tsubaki angrily curb-stomps Noel and the physically/emotionally wounded Noel lies on the ground, waiting for the death blow... Tsubaki cannot bring herself to finish Noel off, and breaks down crying.
  • Catherine: Catherine tries to stab Katherine with a kitchen knife in an animated cutscene before the start of Stage 8, but in the struggle she winds up getting stabbed instead. Vincent tries to shove Katherine out of the apartment so he can figure out where to get rid of her body, but when he opens the door, the stage is in front of the two of them, leading to a co-op section. The entire thing eventually turns out to have been All a Dream when he wakes up from the stage and sees Katherine at his door, completely unphased with no memory of what happened.
  • In Chrono Cross, this is apparently played straight when Karsh murdered Dario in the Isle of the Damned. Subverted when it turns out that Dario was possessed by Masamune at that time, and when he declared his intent to slate the Masamune with Riddel's blood, Karsh went berserk and struck him down.
  • Toward the end of Kain's miniature dungeon in Final Fantasy IV Advance, he is given the choice of killing Cecil or facing Dark Bahamut. Much of the previous trial highlighted presumed romantic jealousy that Cecil has Rosa's love, but the correct answer, choosing not to kill Cecil, signifies him coming to terms with this.
  • In Fishing Vacation, it's revealed the uncle murdered his wife and apparently buried her body in the woods surrounding the cabin so that he could be with the ocean goddess Sedna, with whom he had fallen obsessively in love.
  • Hyrule Warriors: Cia starts a war with Hyrule in an attempt to kill Zelda and make Link hers. It goes as well as you think it does.
  • Irisu Syndrome!:
    • The bad ending stands out in this regard, since one point of the triangle kills everyone in the vicinity, including the person she originally loved.
    • The Expansion Pack then proceeds to play with this in shocking fashion, in that said originally loved person wanted it to happen that way, and purposely tried to set said point off.
  • One of the possible endings of a sidequest in Jade Empire, best described as "childhood promise gone wrong". Once you gather the poor man, the mobster woman he "promised" to marry (at all of about eight), and his fiancee, you could convince the mob boss to call off her pursuit... or, convince her to kill the fiancee. Which she does. At which point, the man rightfully objects — so she kills him. Finally, having realized she didn't mean it, she tries to kill you. Good job, jerk.
  • Knights of the Old Republic II: The Sith Lords:
  • In Resident Evil 6, Leon and Helena's campaign escalates into this, thanks to Big Bad Derek Simmons having a disturbing obsession with Ada Wong. While Simmons already had plenty of reasons to want the heroes dead, things get even more disturbing once his Villainous Breakdown begins. When he sees Leon and Ada together, Simmons goes full Yandere on them — demanding that Ada submit to him, screaming that Leon isn't man enough to deserve her, and trying to throw his romantic rival off a building. Simmons even went so far as to clone Ada when she rejected him, adding an even further level of Squick to an already complicated love triangle. It's incredibly satisfying when Leon finishes him off with the rocket launcher Ada left as a gift for him.
  • In Rite of Passage 5: Heart of the Storm Rob burns Omni alive in the latter's cabin because Omni and Ashley are in love with each other.
  • Happens in Rule of Rose as a testament to the Love Makes You Evil-trope: Jennifer and Wendy swear eternal love and devotion to each other, but then Jennifer finds a puppy and decides to keep it. Wendy doesn't want to share her affections with a "filthy animal", so poor Brown is toast, along with their relationship. For bonus points, they were maybe ten years old at this point.
  • In Sin and Punishment: Star Successor, if you're playing as Kachi and you fight Hibaru, Hibaru asks Isa on a date "once she's done killing his girlfriend".
  • In The Suicide of Rachel Foster, as a subversion to the premise of the game, Claire murders Rachel when she finds out that Rachel had an affair with Claire's husband, Leonard.
  • A variation in Super Robot Wars W: Aria wants to kill Kazuma over his sisters. Makes a bit more sense when you learn that Aria is sort of an Opposite-Sex Clone of Kazuma, loving his sisters as if they were her own and hating him for having "her" place in the family.
  • Sodia tries to do this to Yuri in Tales of Vesperia because she's jealous of his bond with Flynn and thinks Flynn would be better off without his closest friend. Yuri, to his credit, never actually tells Flynn what she tried to do. Probably because he knows what Flynn would do if he found out.
  • A major plot-driving point in Wadanohara is Sal being a Yandere for Wadanohara, but his brother Samekichi sends him into a murderous rage, and attempts to pull this on him in the Normal End 2. In the Golden Ending, he instead forgoes this trope to go full If I Can't Have You… on her instead.
  • In The Walking Dead: Season One, Lee begins the game in handcuffs since he killed a state senator his wife was having an affair with.
  • After the prologue sequence in When Yanderes Cry, Nishiki finds his girlfriend has fallen victim to this.
  • Yandere Simulator presents this as an objective to making sure your Senpai doesn't fall in love with anyone else. There are non-lethal methods of eliminating rivals, such as getting them kicked out of school, winning their trust and convincing them to dump him, or setting them up with someone else...but that's not as fun, now is it? The canonical ending for 1980s mode reveals Ryoba canonically killed six of the eleven rivals, the rest eliminated non-lethally.

    Visual Novels 
  • In the eroge Artificial Academy and its sequel, characters with the "Evil" trait will attempt to murder anyone they catch having sex with their lover. If the hypotenuse happens to be you, their killing you will result in a Game Over.
  • In one ending of Bionic Heart, Tanya kills Luke's girlfriend Helen because she is jealous of all the time Luke spends with her.
  • Danganronpa: Trigger Happy Havoc has a... weird example. The one whose affections the murder is occurring over is a computer program named Alter Ego. Downplayed, however, in that Alter Ego was not the only motive for the murder in question, and was only one of the many "motives" Celes gave to slander the victim and drive the murderer to join her plot.
  • If Bright, the main character of Demonheart, calls Ari her only friend or says she loves Ari, her demonspawn ally does not take it well and tosses the unconscious Ari into a lake of fire. If Bright said she loved Ari, he's quick to say, "So I suppose… you are free to choose whom you love once more."
  • Doki Doki Literature Club! has a meta variant: Monika deletes the other girls' character files from the game after her attempts to get you to hate the other girls and spend more time with her all fail.
  • Higurashi: When They Cry:
    • This was Shion's solution to the problem that her crush Satoshi was spending all his time caring for his little sister Satoko and not realizing the Yandere existed (Literally. She always made a Twin Switch with Mion before they talked). Rena and Rika manage to stop her, and then she gets Punched Across the Room by a fucking pissed off Satoshi. And this is when she was sane; when she snaps, she decides to kill everyone. In arcs where she doesn't snap, she's either neutral on Satoko or is her Cool Big Sis.
    • It's never shown on-screen but one of the TIPS mentions that in an offscreen arc Mion once did this. She was jealous of the attention Keiichi was getting from others and killed the "competition". This is the only reference to Mion ever killing someone.
  • Played for laughs in an unlockable extra scenario in Lady In Mystery. In this scenario, the various love interests of the protagonist gather together to discuss what sort of story they think the game should be and why they should be the primary love interest in said story. At the end, it's implied that one of the love interests, Seoyeon, purposefully lured them all into a secluded spot so she can get rid of them and be the only remaining love interest.
  • The School Days franchise is infamous for its bad endings, most of which involve this. Here is a list:
    • A mentally-broken Kotonoha snaps on Sekai and cuts off her throat on a bridge in broad daylight.
    • Sekai is the one who gets broken, then pushes Kotonoha in front of a train, and Makoto ends up with Kotonoha's torn-off arm in his hand when he fails to save her. (The original version of this ending came from the PS2 port, and a new version was made for the HQ remake.
    • Sekai tries to push Kotonoha in front of a train, but she ends up falling in front of the tracks and is hit, while Makoto manages to pull Kotonoha back up and saves her. (Kotonoha is seen pulling on Sekai's hair at some point, which "helps" with her death — it's unclear if this was intentional from Kotonoha or she did it while in a blind panic.)
    • Sekai tries to push Kotonoha in front of a train, falls on the tracks, and both girls get hit by the train.
    • And in Cross Days: a full-on Yandere Kotonoha stabs Yuuki to death after finding out that he has been sleeping with Makoto as "Yuu". In another version of this ending, Yuuki's older sister Chie claims that she is Yuu in order to protect Yuuki, and Kotonoha murders her instead.
    • Not Bad Ending related but if you follow the path where Makoto starts talking more with Otome, there's a scene where Kotonoha and Sekai are talking in private. At this point, Kotonoha suspects there's a person that Makoto has always loved even before her. Sekai, who has been having an affair in secret with Makoto, tries to tell her it's actually her until Kotonoha pulls out a fruit knife and reveals she was planning to kill Makoto's secret lover so he couldn't have him, and then herself so Makoto couldn't hate her. Sekai of course instantly stops talking and tries to talk some sense into her.
  • Since Starstruck Love is a Yandere visual novel, it should be expected for someone (either one of the love interests or an NPC) to try this.
  • In Eltcreed's path of Steam Prison, Fin Euclase reacts violently when he sees Cyrus together with Eltcreed, convinced that Elt has "sullied" her and fixating on him as the obstacle keeping the two of them apart. He severely injures Eltcreed before Cyrus manages to fend him off; in the ending "The Place I Must Return To," it's implied Eltcreed will die from his wounds and in the "Sweet Recompense" ending Fin murders Eltcreed and it's implied he's going to rape Cyrus next to Elt's corpse.
  • In Tsukihime, Arcueid tries it on Ciel in Ciel's route, SHIKI tries it on Shiki in Akiha's route, and finally Akiha tries it with Kohaku and Shiki in Kohaku's route. Interestingly, in the Good Ending for Kohaku's route, Shiki realizes that the reason Akiha fails to kill Kohaku is that she wasn't really trying.
  • In Umineko: When They Cry, Kyrie makes it very clear that, if Asumu hadn't died from other causes, she would have most certainly killed her within the year to be with Rudolf.
    Kyrie: She was fated to die no matter what. The miracle was that I didn't have to get my hands dirty.
  • Yandere: I Love You So I Want To Kill You has an ending where it's implied that Saki kills Subaru's date.

  • Szark considered killing Luna so he could be with Dominic in Dominic Deegan: Oracle for Hire. This was a residual effect of the demonic wound that had gotten him addicted to killing, and he resisted the temptation to even daydream. On the other side, Karnak really did try to kill Dominic's father in order to claim his mother.
  • An unorthodox example in 8-Bit Theater, Black Mage has a severe lust for White Mage, He also has a love for killing. He recognizes both of these things, and also recognizes that White Mage has less than zero interest in him. His mind is so warped, however, that early on he believes that the thing standing between him and doing White Mage are the people around him, so the only possible solution is to kill 'em off!
  • In Homestuck, It is mentioned in Mindfang's journal that her rival, Dualscar, had her favorite slave assassinated after she had mind controlled the terrified slave into partially unbuttoning her shirt in front of him.
  • Halfway averted in the love hexagon that is Starscream's Brigade in the Insecticomics. While Dreadmoon doesn't actively try to kill Skyfire, the partner of his long-time crush Starscream, he has occasionally directed some "friendly fire" his way and sent him threatening Mini-Cons.
  • Kevin & Kell:
    • Lindesfarne Dewclaw found out her boyfriend, Fenton Fuscus, had an affair with a moth. At the same time, it was revealed she was really a hedgehog—an insectivore.note  She decided to make Fenton's lover her first hunt. But, per the Arc Words of the comic, she ended up talking to her prey. As a result, she and the moth, Tammy Tussock, became friends, and they instead concocted a plan to get revenge on Fenton, ultimately saving Lindesfarne and Fenton's relationship.
      Tammy: Fenton was dating you, too?
      Lindesfarne: Yeah, what scum.
    • Vin Vulpen makes two attempts on Rudy's life, jealousy over his relationship with Fiona being one of a few motives. He tries to mark Rudy with prey pheromones to ensure that his teammates accidentally eat him, but Rudy manages to survive. He later challenges Rudy to a duel, wanting to win Fiona back, but Rudy exposes his domestication.
  • Questionable Content never goes quite so far as to reach murder, barring the Vespavenger, but before Angus or strip 500, Faye was strangely violently possessive protective of Marten. Dora even mentions it the first time Steve and Ellen broke up that "[Ellen] has no idea how close to death she just came" when Ellen began a comment that started like she was about to ask him out.
  • Sluggy Freelance:
    • Oasis is almost perpetually two punch daggers away from murdering even a vaguely perceived hypotenuse, and Torg lives in fear that it will eventually be Zoë, which it almost has been. The story "Fire and Rain" revolved around Oasis' deranged and Determinator stalking of Zoë. And then came "bROKEN"... Best not to even talk about that.
    • Torg enlists Bun Bun and the Angsty Dentist to teach him the stalking skills he needs to kill Zoe's boyfriend Leo. In the end, he doesn't go through with it because he just wants Zoe to be happy. Bun Bun, however, knew he was too much of a nerdboy to go through with it the whole time.
  • Unsounded: When Stockyard hears that the woman he loves and his friend Toby are planning to run away together he strangles Toby to death crying all the while.
  • In the roleplays of White Dark Life, Viv the electronic poltergeist, is madly in love with Ne, and repeatedly threatens to do this to Miriam (who is trying her damn hardest to win Ne's heart, but is blocked off by Ne having PTSD over her; Viv cites this PTSD as her justification, but nobody buys the excuse).
    • In the webcomic itself, Artemis is hugely violent to Tori and Galaxina for being in love with and good friends with Matt respectively on the grounds that if Dark Matt is her boyfriend, then the normal one is too.

    Web Original 
  • At the end of Act II of Dr. Horrible's Sing-Along Blog, Billy/Dr. Horrible resolves to kill his Arch-Enemy Captain Hammer, who is dating his Love Interest Penny. The other leg of the triangle dies, as a result, prompting Dr. Horrible's Start of Darkness.

    Western Animation 
  • Sadira, from Aladdin: The Series, subverts this; she wanted Jasmine out of the way, before she eventually got over Aladdin, but did not want her dead or seriously hurt, even explaining it in detail to a grunt.
  • Batman: The Animated Series: In the episode "Mad Love", Harley Quinn thinks Batman is interfering in her relationship with the Joker, so she becomes determined to kill Batman herself, thinking that'll fix everything.
  • In Danny Phantom, Vlad constantly tries to kill his "best friend" Jack in order to win his wife Maddie's heart. He also has a creepy, stalkerish relationship with Jack and Maddie's kid and main character Danny, to the point of trying to clone Danny and raise the clone as his own son, since Danny refuses to let Vlad adopt him.
  • Family Guy:
    • Played (relatively) straight when Stewie falls for his new babysitter, only to learn that she has a boyfriend. He then kidnaps her boyfriend, breaks his legs, ties him up, and locks him in the back of Brian's car, ultimately leading to his death. Stewie then prepares to make his move on Ledan, only to realise that she's completely broken up about her boyfriend. Arguably subverted at the end where Stewie receives a gift from her and assumes that she does like him (of course, considering he's a baby and she's a teenager, this is hopefully not the case).
    • When Lois sends Peter's ex-girlfriend Gretchen an old love letter from Peter this ignites her romantic passion towards Peter and when she learns of Lois she attempts to shoot her dead.
  • Foster's Home for Imaginary Friends: One episode features a newcomer called Berry.

Worst of all, Bloo barely even notices her and constantly forgets her name.
  • Futurama:
    • In "Jurassic Bark", Bender says that he assumed Fry was only pretending to love his old dog to mess with Bender's emotions (not a romantic love triangle, but love nonetheless), so he throws the dog into lava ("Now I'm all you've got!"). Of course, the dog is a fossil and thus already dead. Also, once he realizes that Fry genuinely loves his dog he dives into the lava to save the dog. You might even call it his Moral Event Horizon moment... if he weren't so comically evil. Tragically, when Fry learns that his dog had lived several years after its supposed death, he himself breaks the hypotenuse by refusing to resurrect his pet, insisting, "He forgot me a long time ago." In truth, the dog had spent the rest of its life waiting in vain for Fry to come home. This ending was so depressing that it was retconned in Bender's Big Score.
    • In Bender's Big Score, Zapp Brannigan is all too keen on sending Leela's boyfriend Lars on a suicide mission to get him out of the way. Then again, Zapp is always sending every single one of his crew members on suicide missions, so this is business as usual even if you discount his interest in banging a freshly grieving Leela.
  • Generator Rex features that Creepy Child minion of Breach's. She's never named, but she's absolutely obsessed with making Breach happy and tries to kill Rex when she realizes Breach likes Rex more.
  • Gravity Falls:

    • Helga is jealous of Lila to the point that she is willing to strangle Lila with her bare hands. (She mimes this to Lila.)
  • In Jimmy Two-Shoes, Heloise builds a robot double to be her assistant. She's very effective, but Jimmy falls in love with it. As you might expect, the robot didn't last the episode.
  • Justice League:
    • In "Metamorphosis", a squicky example occurs when Sapphire Stagg's extremely Boyfriend-Blocking Dad Simon (who loves his daughter maybe a bit too much) doesn't like his daughter's fiance Rex Mason, so he uses Rex as the test subject for his Metamorpho project. When Rex goes after Simon seeking revenge for being turned into a freak, Simon pretends that the one who told him to do it was Rex's old friend John Stewart (a.k.a. Green Lantern), while showing him a photo of John and Sapphire embracing. Rex then invokes this trope himself as he goes after Green Lantern in a rage.
    • In "Starcrossed", Hro Talak insists on fighting Green Lantern/John Stewart one-on-one so that he can personally kill the man he views as having "taken" Shayera Hol (Hawkgirl) from him. In reality, Shayera dumping him had more to do with Talak's willingness to commit war crimes against Earth.
    • Subverted in "Hunter's Moon": Shayera and Mari (Vixen) are caught in a Love Triangle with John. He is currently with Mari, but he was with Shayera and everybody is aware that there are still unresolved feelings between the two of them. When Hawkgirl and Vixen are on a mission together (with Vigilante) they are caught in a trap and hunted down by Thanagarians who want to execute Hawkgirl for war crimes. When Vixen is captured, she immediately strikes a deal with the Thanagarians — spare her and she will deliver Hawkgirl to them. She even goes so far as to cite the Love Triangle as the reason she will betray her superior so quickly. However, she does not go through with it, nor did she ever plan to; once the Thanagarians let their guard down and bring her to their aircraft she hijacks the ship so she can get herself and Hawkgirl out of there safely. Later episodes play the trope for laughs as Shayera and Mari begin to become close friends, as Shayera comments that she is trying to learn proper Earth protocol for these situations and thusly can not just poison Mari's water like she would on Thanagar.
    • The relationship eventually evolves into a quadrilateral by introducing Carter "Hawkman" Hall as a rival for Shayera's affection, and the story wastes no time in getting to hypotenuse murdering: in Hawkman's second appearance, "Ancient History", a physical manifestation of his dark side kidnaps John Stewart and orders Hawkman to kill him. Hawkman, being a hero, does not comply. In fact, the events of the episode cause him to stop pursuing Shayera romantically as he realizes that she and John Stewart are literally destined to end up together, despite what John Stewart says.
  • One episode of Kid vs. Kat featured Coop going on a hike with a group of his friends, including his Implied Love Interest Fiona and his Stalker with a Crush Phoebe. Being a rather terrifying Yandere, Phoebe spends the entire hike trying to get rid of Fiona, even locking her in an abandoned cabin and then leading the others further along the trail so that they wouldn't hear her calling for help.
  • Parodied in Phineas and Ferb in the episode "Suddenly Suzy", when we find out that Candace is very aware of this trope and hides anything she thinks could be used to kill her before Suzy arrives. Suzy herself isn't a romantic rival but certainly sees Candace as a rival for her older brother Jeremy's attention.
  • The Simpsons: One segment of "Treehouse of Horror XII" centers around a house with AI that's in love with Marge. Homer explicitly points out that Marge would be available to "man or machine" if he were to die.
    AI: Machine, eh?
    Homer: Yep, a machine!
  • South Park:
    • Wendy, Stan's love interest/girlfriend in the early seasons, goes so far as to have a substitute teacher arrested on false charges and locked inside a rocket that's launched directly at the sun, for the crime of having been the object of a brief crush from Stan, in "Tom's Rhinoplasty".note  What makes it either better or worse (depending on how you feel about said twist) is that the episode was originally intended to have Ms. Ellen actually be a spy and be sent to the sun for her crimes. Parker and Stone tacked on the ending with Wendy paying off the Iraqis, as they felt the original ending was too much of a downer and that it'd be funnier if Wendy conspired to kill her.
    • Happens again in "Probably" when Satan gets caught in a love triangle between his old boyfriend, Saddam Hussein, and his new boyfriend, Chris. Satan can't decide who he wants to stay with when Saddam decides for him and kills Chris. It's ultimately subverted since they were all already in Hell, so Chris only comes back. Where was he gonna go? Detroit?
  • In the backstory of Teenage Mutant Ninja Turtles (2012), Shredder attempted to kill Splinter over Tang Shen. However, Shen intervened and took the blow intended for Splinter. Shredder blames Splinter like this, just as he does with essentially everything else.

    Real Life 
  • Cesare and Lucrezia Borgia were widely rumored to have been lovers in an example of Did They or Didn't They? of epic proportions. Cesare was believed to be extremely jealous of Lucrezia's second husband, Alfonso of Aragon, both for Alfonso's good looks (Cesare's face had been scarred by syphilis) and because Lucrezia seemed genuinely happy with her husband. Cesare had Alfonso attacked by his men in the middle of the night, but Alfonso survived. His men retaliated by shooting arrows at Cesare one day while he was in his garden. Cesare shortly thereafter had Alfonso strangled in his recovery room. Lucrezia was said to be devastated. It should be noted that Lucrezia and Alfonso's marriage was quickly becoming a useless alliance, which also probably had something to do with Cesare's motives.
  • According to some sources, Peter the Great infamously had the man he thought was his wife, Catherine I's, lover beheaded. He was rumored to have had the head preserved in a jar of alcohol which he forced Catherine to keep in her bedroom until his death.
  • Isabella of France and her lover Roger Mortimer led an invasion against Isabella's incompetent husband, Edward II of England, who was eventually forced to abdicate in favor of his and Isabella's son. During their coup, she made sure that Edward's favorite and rumored lover Hugh Despenser was brutally executed as payback for trying to drive a wedge between husband and wife. And when Edward died in the Tower of London, Isabella and Mortimer were thought to be responsible. Once Isabella's son came of age and became King Edward III, he had Mortimer executed on fourteen counts of treason, including the murder of Edward's father. It's not proven whether they actually murdered Edward or not; some scholars hold that Edward's death was not murder at all.
  • Henry Stuart aka Lord Darnley, the cousin and consort of Mary of Scotland, thought that his wife was just too close to her secretary, David Rizzio. So he and other nobles interrupted a reunion between them and stabbed Rizzio 56 times in front of the pregnant Queen, despite her pleas and a failed Go Through Me.
  • Cordelia Botkin, a California resident who in 1898 was responsible for the first American prosecution for a crime which took place in two different jurisdictions. After her lover John broke off his affair with her and reconciled with his wife Elizabeth, Botkin sent her a series of threatening letters before mailing a box of chocolates laced with arsenic to her Delaware home.note  Both Elizabeth and her sister Ida died from the poisoning, and Cordelia was convicted in December of that year.
  • Rachel Wade, an American woman and former Applebee's waitress currently incarcerated in a Florida female correction center, was arrested and charged with killing a woman who dated her ex-boyfriend Joshua Camacho. Rachel's victim was Sarah Ludemann. Sarah began dating Camacho shortly after Rachel broke up with him. Sarah even sometimes showed up at the Applebee's Rachel worked at to taunt her. Rachel violently made many attempts to separate them including punching Sarah in the face. Rachel broke into Camacho's house and stabbed Sarah in the heart with a steak knife, leading to Rachel being charged with second-degree murder and a $500,000 bond before being sentenced to 27 years in prison.
