Fan Fiction in general
- Any Die for Our Ship fanfic often turns one half of the canon couple into this in order to better enable the author's personally preferred couple.
- There are fanfics where the reader may insert himself/herself in the story with a yandere character. They may be normal characters turned into yanderes, they may be characters who boarder on or could be yanderes. Heck, the reader could be the yandere. Have fun sleeping after reading one of those!
- In Somebody That I Used To Know Matt Engarde becomes this for Juan Corrida, towards whom he becomes increasingly obsessed with and possessive towards (in a very abusive way); it is heavily implied that he is responsible for Celeste Inpax's apparent suicide, after he fails to scare Juan into breaking up with her; the fact that her death happened not long after she and Juan had announced their engagement, and all of Matt's attempts to get Juan to call it off had failed, is rather telling.
- Many countries that are seen to be more... jerky in Real Life and historically are often characterised this way. It's even led to many different Alternative Character Interpretations, to the point where Hetalia has a page of its own there.
- You literally just have to search 'yandere' on FanFiction.Net to get around 100 results for Hetalia that have the word just in their title or summary. Sure, they aren't really of the best quality, but it's telling of how many people write such things.
- Suzaku isn't one in My Mirror, Sword and Shield. But history believes him to be one note . What the historians know that he had a relationship with Emperor Lelouch who awarded him with the highest knighthoods and that Suzaku was so loyal that he betrayed his people, killed the innocent Princess Euphemia when she gets in Lelouch's waynote and won Lelouch the War of Ascension by killing everyone in his way.
- The Harry Potter and Black Butler crossover Harry To Akuma interprets Dudley Dursley as one. Dudders really likes his cousin Harry but since his parents have forbidden him from being friends with "the Freak" (and encourage him to beat him) he decides that if he's not allowed to be Harry's friend than no one else should either and it's out of jealousy that he runs off the many people who want to be Harry's friends.
- The Magical Girl mega-Crossover Shattered Skies has Tomoyo, of all people, go yandere for "her" Sakura-chan...
- Ottabio from Sky Rose hated so much to see Rosabella corrupted by Xanxus he betrayed his own Boss to the Vongola. Then he tries to force a Guardian bond on Rosa, because she belongs to him and it's for her own good. For extra creepiness, Rosa is a ten years old girl.
- In A Cure for Love Light begins a relationship with L during his Memory Gambit but when Light becomes Kira again he becomes very possessive and obsessive of L. He begins making up excuses to himself why he isn't going to kill him now like "it's not a good time," or "I want to break him first" (suggesting he really does love him underneath the psychosis. Light becomes very angry and upset when someone else tries to kill L.) Light arranges things so that Misa kills Watari, and then he kills her because he felt threatened that Watari was going to make L break-up with him and that Misa, a Yandere herself, would try and kill L so that she and Light could be together. Light keeps L drugged up for weeks afterwards and spends so much time with him that his infatuation becomes rather obvious to everyone at which point Light even considers killing his own father because he's against their relationship. Later when L in effect breaks up with him, Light goes completely off the Morality Chain. He uses the deaths of his father and a former teammate to essentially takes over the world in an afternoon.
- In Death Note: The Abridged Series (kpts4tv) Light towards L:
Light (with red, Glowing Eyes of Doom): I loved you L and you smashed my heart into a million pieces. I will never love again.Ryuk: Light, uh... you're scaring me.Light: Oh Ryuk, I haven't even begun to scare you yet! (Evil Laugh)
- In Light and Dark The Adventures of Dark Yagami there's the "girl from the bus", who kills Dark after she's left out of the group hug.
- In Monster Light is this for L while Misa is this for Light:
Light (coming at L with a knife) L, I'm not losing you again.
- Light is portrayed as one again in this L/Light AMV: "Never Wanted to Dance" (spoilers).
- Lampshaded in Office Politics which again has Raito towards L:
Granted, Raito is a terrifying, jealous, power-hungry, arrogant sociopath serial killer, but these are all things that L knew the first time he and Raito played six hours of mind games that led to strip poker and somehow anal sex. It was really rather unfair of him to simply abandon the game mid-session; it wasn't as if he wasn't allowed to change the rules. Perhaps, he'd been hasty.
- In Ragnarok Takada towards Light. When Light began dating her in college they agreed it would be nothing serious since they both wanted to focus on their careers. But when Light broke up with her Takada did not take it well and has held a grudge for four years and seems to be out to ruin Light's career.
- In Fade, L has a history of being one:
- L, for Light. He became more infatuated and obsessed with Light ever since L read their fates in the Death Note. He becomes very obsessive and possessive with Light, forcing Light to be with him at all times and getting angry and violent when Light thinks of leaving him of spending time with others. L even has Light's family and friends killed so Light would be dependent only on him.
- Light isn't the first person to invoke these feelings within L. L acted similarly with A, which was a problem because A was sociable and kind. The only other person L could tolerate spending meaningful time with A besides himself was Beyond, and even that tolerance eventually ran out. His jealousy over A's many friendships eventually led to A's death and Beyond and L's estrangement.
- Yandere Sumia, unsurprisingly enough, has Sumia. Enraged at being rejected by Chrom, she kills everyone else he could end up with- Maribelle, Sully, Olivia, Female Avatar and the Maiden- then kills him when he rejects her for being a "waifu killer."
- In Adorable Violence Hermione deals violently with anyone who gets between her and 'her Harry' or her books. The two of them have a contract in place to set limits on her violent tendencies.
- In Do Not Meddle In The Affairs Of Wizards Ginny is a Yandere who stalks Harry to the point where even Yuno Gasai would have been going '... a bit much, surely?', deliberately impregnates herself with stolen sperm and then tries to use the test-tube-child to trap Harry into marriage, and nearly kills Luna for the high crime of talking to Harry (although in fairness the part where Luna almost died was an accident — Ginny didn't know that Luna was seriously allergic to bee stings).
- In Dumbledore's Army and the Year of Darkness, Hannah Abbot (Neville's future wife) tries to set him on fire and then throws several potted plants at him (one of which suffocates him to unconsciousness, while she does nothing to stop it). All this because of a bad case of Poor Communication Kills leading her to believe he was making out with Ginny—even though Hannah and Neville aren't even dating. Either this is supposed to be justified by the "fact" that girls are just crazy like that or a bit of comic SlapStick horribly clashing with the deadly seriousness that violence is portrayed in the rest of the fic. It is possible that this is a continuity nod of sorts to the scene where Hermione sets a flock of conjured birds on Ron, albeit a ridiculously over the top one.
- Fate's Favourite has an odd (allegedly) platonic example where a teenaged Tom Riddle from 1942 becomes very possessive and obsessive of Harry. At first because Harry is interesting and later because he counts Harry as the first real friend he's ever had (on account of Tom being a clinical sociopath who generally just uses people and doesn't feel anything for anyone but himself but he feels something for Harry.) This is Lampshaded by other characters who take to referring to Tom as Harry's "jealous boyfriend." Tom mentions in passing that he's more than willing to watch the whole world burn if it means he can spend more time with Harry and he will eliminate any perceived threats that may come between them.
- In Heir Ginny is Harry's creepy, pathetic, and budding Yandere stalker who keeps throwing herself at him when it's clear he's not interested.
- In If Them's the Rules, another Time Travel Harry Potter fic, there's Arcturus Black who is totally obsessed with Harry to the point that he regularly uses polyjuice on a prostitute to make him look like Harry and he murdered his own wife because she was "getting in the way." But Arcturus isn't alone in disturbing behavior—apparently it's called the "Black Family Madness" because the entire family tends to get unhealthy, destructive obsessions. Also the young Tom Riddle is already quite overly-attached to Harry-he absolutely forbids Harry from getting married or spending any time with that creep Black.
- In Somno Veritas Harry finds that the only thing more frightening than Voldemort trying to kill him is Voldemort's infatuation and getting crazy possessive over him especially since Voldemort never learned to handle emotions before he hacked up his soul so he's very volatile going from displays of kindness to violently psychotic at a drop of a hat.
- In The Jaded Eyes Series Harry/Tristan and Tom/Voldemort for each other. Also Harry's little brother Clark towards both Harry and Harry's adopted sister Suzie, because 1) Suzie rejected Clark and 2) Suzie had Harry/Tristan as her big brother growing up and Harry Potter should've been his brother. So Clark decides Suzie must be a wicked girl that's corrupting Harry and once he kills her surely this "Tristan" will somehow magically revert into the brother Clark always imagined him to be.
- In Marble Serpent Ginny is obsessed with the idea of the Boy-Who-Lived and intends to make Harry hers, regardless of Harry's desires.
- In Un Coeur Gris Ginny is again portrayed as Harry's Yandere Stalker with a Crush.
- Adam of Dalton.
- Savannah Carlyle from If You Only Knew. She begins a relationship with Puck and starts to show symptoms not long after her introduction but it is all culminates with her killing Shelby, Puck's ex. She even sings the Yandere song "This Little Girl" by Cady Groves as her confession.
- Dani in Changing Directions is obsessed with Faith and threatens to rape her, but in this case, her obsession is treated as a disease and she is Put on a Bus to deal with it.
- In the Dark Fic The Sacred And The Profane when Caphriel confronts Zirah about a certain killing spree his response is along the lines of: What it was your idea! Don't you understand, I did it for you! Isn't this was what you wanted?
- The Condesce is often portrayed as having romantic feelings for the Psiioniic. In canon, she wired him permanently into her spaceship's engine so his psychic abilities could be used as a power source; as the fanworks would have it, it was also so he can't leave her. Referenced in Hivefled, in which the Grand Highblood is also distinctly yandereish towards the Handmaid; he killed her, kept her skull, and painted a portrait of her in her blood.
- One of the most common portrayals in the Happy Tree Friends' fanon anime version depicts Flippy - who is an Ax-Crazy, psychotic murderer in Canon- as an Yandere for Flaky. The canon episode Without A Hitch plays with it a bit, because Flippy constantly follows Flaky around, trying to be nice to her, while she is so terrified of him, that she tries to get rid of him at all costs.
- Ultimate Re-Imaginings gives us Natasha Romanov. She tried to kill Joey and blatantly implied she's the one who got Clint's family murdered. And when her attempt to kill Joey backfired the first time she framed Clint before ultimately trying to kill him too because he was spending too much time with Joey.
- And this is to say nothing of how Andrea Rourke is turning out from her previously innocent protrayal as Joey's Shrinking Violet Tsundere Type B friend. And as of 'Over The Edge,' she's officially proven just how fatal her love is. Even more disturbing is that when Joey returns from being kidnapped again he's going to be in for a nasty surprise.
- At first, Ronald Hilliard turned himself into an electricity-spitting monstrosity and began murdering Spider-Woman's critics as a way of displaying his affection for her. When, Ronald, now calling himself Supercharger, professes his "love" for Spider-Woman, she disgustedly points out that she can do without the "love" of a sick freak like him. The resulting Freak Out! leaves Supercharger torn between his obsession with making Spider-Woman his girlfriend and his obsession with torturing and killing her for "rejecting" him.
- Admiral Daro'Xen, the Big Bad of Project Gethinator, is crazy in love (or is that lust?) for Commander Shepard. She's gone into quite in-depth study of Shepard's history and psychology and has determined that he is quite susceptible to the charms of female quarians, and nothing will dissuade her from the notion that she and Shepard were meant to be together. Everyone else working with her (particularly her second-in-command, Hvenna'Tor) considers this aspect of her to be utterly disgusting. It definitely doesn't help that she's written a collection of Self Insert Real Person Fics about herself and Shepard, with a reputation for depravity second only to that of Fornax's Forbidden Issue. When she and Shepard finally face off in the final chapter, when Shepard turns Xen down (because Xen is completely out of her mind and because Shepard is in love with Tali), Xen has an If I Can't Have You... Villainous Breakdown of star-system-shattering proportions — she turns the same mineral scanner that Tali's idiot crewman Prazza (who was responsible for the Forbidden Issue being labeled such) accidentally blew up a star with in the very first chapter of Inglorious Bosh'tets on Eta Carinae, causing it to go hyper-nova in a furious bid to destroy Shepard, Tali and the entire Normandy crew.
- Adrien Agreste in Le Papillon Rising is a Young Conqueror Villain Protagonist who believe Stalking Is Love and has a very unhealthy relationship with Marinette Dupain-Cheng, the secret identity of the superheroine who is trying to fight of Le Papillon, Adrien's secret identity. In his attempts to keep Marinette as his girlfriend, he goes into Manipulative Bastard territory, creating akumas designed specifically to destroy any threats to their relationship. The Evillistartor becomes this as well, attempting to kill Papillon because Marinette thinks Papillon has pretty eyes and is very physically attracted to him, although she knows him to be a villain.
- Randall's ex-girlfriend Sylvia Schneider from Angela's Pet Monster is completely Ax-Crazy and will murder anyone who she sees Randall show any sort of affection to.
- Poor Fluttershy tends to get this treatment in fan works because of her infamous "YOU'RE GOING TO LOVE ME!!!" flip-out in the original series. Some of it's enough to make you feel really bad for Big Macintosh, or Rainbow Dash, or whoever else she's going Yandere on at the time. The rest is flat out Nightmare Fuel.
- A famous example is this audio drama. Fluttershy chases the viewer into his house after he apparently saw her murder one of her friends.
- Played for laughs in the rather bizarre story, ''Stealing the Deed'' when it seems that Trixie has become a very strange and desperately in-denial version of this. Just about everything she says in this story is either filled with unadulterated Insane Troll Logic, or both confirming and attempting to deny her yandere-ness.
Trixie: TRIXIE HATES YOU SO, SO MUCH! SO MUCH SO THAT SOMETIMES TRIXIE LIES AWAKE AT NIGHT AND SNIFFS THE LOCK OF YOUR MANE SHE TOOK FROM YOU WHILE YOU WERE SLEEPING AND DREAMS ABOUT HOW NICE IT WOULD BE TO BURY HER MUZZLE IN YOUR MANE AND FALL ASLEEP LIKE THAT!Twilight Sparkle: Wow... uh... I had no idea you erm... hated me so much? I mean... I guess I'm flattered that (Beat) Wait! You came into the library while I was sleeping and stole some of my hair?!Trixie: Uh... Trixie has a very good explanation for that!Twilight Sparkle: I'm listening.Trixie: Trixie, in fact, does not have a very good explanation for that...
- The Benefits Of Friendship Come With Consequences has Twilight slowly transform into a yandere. It's played completely straight, to the point where Rainbow Dash (her love interest) flat out states that she's close to losing her trust and the local goddess of love has to step in to rebalance Twilight's psyche.
- Played for laughs in The Unexpected Love Life of Dusk Shine. While espousing her love for Dusk, Rarity gets distracted by jealousy:
How dare that little worm steal your first kiss? I don’t care if she was Celestia’s long-lost sister, I don’t care if it was her party, and I don’t even care if she was alone on her precious moon for thousand years, NOPONY TOUCHES MY-
- Twilight in Friendship is Witchcraft is this way towards her adopted brother Francis. Her first words to his fiancee Cadance are literally a song that goes "Hi there! I will destroy you and steal your fiance!". Everypony loves Parody Sue Cadance except for Twilight, who is very much the Villain Protagonist of the series in other episodes and this is only most obvious in Foaly Matripony'. She spends the episode hating Cadance and produces Blatant Lies like her kicking babies in the face and having devil horns. The episode ends with Twilight chasing Cadance off during her own wedding and marrying Francis herself. It's shown that Twilight possibly tortured Cadance before leaving her to die in a cave.
- Rei in Advice and Trust is an unusual case since she's yandere towards her Love Interests and their relationship. She loves both Shinji and Asuka but she refuses to pursue them romantically since she won't risk disrupting their relationship. However, no one else is allowed to romance either of them... or she'll get angry. And she's scary when she gets angry.
Rei stared at her right hand. She never made her body move so fast before. There hadn’t been even a second of thought, just the sudden urge to slap him until he stopped saying such rage-inducing things. ‘Those are MY loves, you invader! MINE! AWAY! HISSSSSSSS~!’
- The Child of Love: Subverted. Rei is pretty jealous of Asuka but she is not mad with her and does not want to hate her. On the other hand Asuka is jealous of AND mad with Rei, thinking she wants to steal Shinji away. At the beginning she treats Rei hostilely… until she calms down and realizes she is just being irrational.
- Evangelion 303: Saburo broke up with Kaworu and regretted it later. However Kaworu does not want him back so Saburo resorts to lash out against his perceived rival- Rei- and stalk Kaworu. He shows up in Kaworu’s house uninvited, he gets angry and jealous when Kaworu spends time with Rei… He knows that it is wrong and he should step out of the way, but he does not know how to.
- HERZ: Kurumi is dangerously obsessed with Shinji. She took advantage of him when he got drunk, and when she met him seven years later she still chased after him obsessively even though he was a married man and a father (bonus points by stalking him in the men’s locker rooms and then chasing him down their workplace despite of being naked).
- Hilariously, Shinji Ikari for Kaworu Nagisa in Playing With Fire, who tries to force Kaworu to complete Instrumentality so they would be together forever instead of killing Kaworu. Shinji admits that he would rather let the world die than separate from Kaworu, refusing to harm the one person unconditionally kind to him. Which causes Gendo to realize that Shinji is truly is his son as Gendo's one to Yui.
- Thousand Shinji: Deconstructed with, of all people, Rei. After Shinji and Asuka got together she realized her feelings towards Shinji. At the beginning she just tried to be happy for Shinji, but she got increasingly obsessed with Shinji and she yearned for getting Asuka out of the way. It got so bad that she often dreamt of killing Asuka. Still Rei restrained herself, thinking that if she killed Asuka, Shinji would hate her forever and kill her or, worse still, he would kill himself.
- Pokemon: The Shadow Of Nemesis: Melody Avery Hemlock from this Pokemon Play-by-Post Game is one of these. A lonely girl who starts on her Pokemon journey in the hopes of finding a friend, she quickly attaches herself to another girl named Abigail, who she declares is her "Best Friend Forever". Anyone who threatens Abigail from that point onwards is soon faced with the brunt of Melody's homicidal urges.
- Serena from the Pokémon anime often gets portrayed as this, even by fans, towards Ash. Considering she's the first female companion to have a canonical childhood crush on him, it's not hard to see why.
- Insane Insight: In this fanfic, Sayaka goes full-on yandere for Kyosuke to the point of killing Hitomi. But then she's not the only one who goes yandere.
- You're Mine: In this fanfic, Homura's obsession and possessiveness toward Madoka are cranked Up to Eleven to the point of killing Sayaka, Mami, Kyoko and also kidnapping Madoka.
- Chapter Two of Magical Challenges features Yandere Mami who committed many atrocious murders that would make Shion Sonozaki proud. Completed with her Sanity Slippage: "If Madoka has turned into a Witch... Then the whole world has no choice but to die!"
- The fic Pyrrha(c) victory turns Pyrrha into one, in a show of OOCness that is both canon-butchering and extremely hilarious.
Pyrrha shook the thought out of her head. She wasn't going to resort to sexual harassment yet.
- Weiss Reacts: Velvet is given this characterisation due to the fic having been written in Volume 1. Exceedingly Played for Laughs, as Velvet is also an Ineffectual Sympathetic Villain and an Anti-Villain- she refuses to hurt her friends and wants to find an 'honorable' way of having Weiss all for herself. She also lampshades this as apparently there is No Fourth Wall for her.
- This trope is surprisingly a Cult Classic among the fanbase. Each female cast member will be portrayed as this one way or another, even Cinder, Glynda, and Winter.
- Just an example, just read this fanfic about Yang acting as one.
- The Simpsons fan-created character Mara Morrigan, originally from unfinished fanfic "Bart Simpson's Obsession" but since then appearing in other works by various fans, is the sweet-seeming but secretly Ax-Crazy cutie with an unrequited love for Bart. The original fanfic was supposed to have ended with him having her committed to an institute to save his own life.
- Bart Simpson Attorney At Law: Jessica Lovejoy evolves into this by leaving threatening phone calls for Alex, and later kidnapping Bart and drugging him into saying a marriage vow.
- Played for laughs on the Uh Oh, Splatfest Alert! tumblr, where Marina acts like this towards Pearl. Specifically, in the vein of "If I Can't Have You...", so she spends her trying to seduce Pearl, trying to kill her or both at the same time.
- A common interpretation of Starscream/Megatron.
- Vicki in The Jill Gilbert Saga is very violent towards Jill, even more so when she becomes a vampire. Jill has hints of one herself and fully becomes one when Klaus tells her turn off her feelings that don't involve him.
- Yukari was a maternal one in Mine towards Reimu, who is, at the time, about one and a half years old (ergo, an infant), and was more than willing to take Reimu to the grave with her, literally. Her reason for this was because she was Reimu's wet nurse and, in breastfeeding her, grew attached and didn't want to give her back to her birth-mother (the then shrine maiden), as she's cared for her since birth and sees herself as being Reimu's mother, ergo she is more than willing to kill herself and Reimu, too, just to keep 'her baby' from being taken from her, making her Type 1: Possessive. However, she is a mild one as she would have only killed herself and Reimu too as a last ditch effort but her willingness to do it at all shows her attachment and exactly how unwilling she was to let Reimu go. Of course, she only said she would but, if she fled and Ran still continued to chase her down further, it would be likely she would have gone through with it or fled to the Outside World, though the former is more than likely than the latter.
- Definately played to a minor maternal sort in Touhou MAMA, a crossover of the Touhou Project and the film Mama where Yukari, playing the role of Mama/Edith Brennan actually does take Reimu to the afterlife with her just to keep from losing her, with Reimu, playing the role of Lily, happily going with her "Mama". As a matter of fact, when Reimu is taken to be with her family, Yukari decides she wants none of it and is not going to allow anyone to take her 'child' away from her without raising hell first, thus it escalates to her spriting people away and causing Gensokyo to descend into a panic over the events.
- In The Phoenix Diaries, the titular Phoenix Force note gets very possessive of Cyclops:
Entry 725: Oh, Scott. Now that we're together you're thinking about how your exes weren't that bad? This... this won't do. At all. Just so you know, the only reason I'm allowing a genocidal lunatic and a race traitor to beat you within an inch of your life is because I love you.
- Rin, Tei, and Mayu all count as this in the Vocaloid fanfic Rotting Camellias, Rin has an unhealthy and literal attachment to her brother, Len, stating that she's glad that the two of them have been stitched together, because that means they can be together forever and acting generally annoyed whenever he gives attention to Tei. Tei, meanwhile, threatens Miku with a knife for even thinking of interrupting her time with Len. But it isn't until the very climax of the story that we see Mayu take her rightful place as yandere queen when she kills Cul when she realizes that Meiko loves her more.
- New Dawn has three of these:
- Claudia Bartlett is one you would never expect. At first seeming like an inhumanly stoic character with Mrs. Robinson vibes, her affection for Matthew seemed purely superficial and based on his physical attributes. She does not really care that she is his teacher, only that her husband - an insurance manager - is never around to "take care of her needs". It turns out Claudia is madly in love with Matthew...because he looks like Dad, who she's had sex with previously. She tries to drug him with Rohypnol in the victory party over Nebiros, and comes very close to molesting the poor guy. She then becomes convinced she needs to kill her husband for him to love her.
- Much more maniacal is Joshua-Antonio, who has a Psycho Supporter thing going for Nebiros. He "does not want anybody but Matthew to challenge Nebiros", viewing his service as basically an act of love, and serves Nebiros not for a vendetta against society or against certain sub-cultures, but because he genuinely loves his boss. Nebiros being a deformed Monster Clown has not impacted this in the slightest. He actually becomes very, very angry when Wayne Reverie speaks badly to Nebiros.
- And the last is Katherine Daille. Consider that she is actually mentally ill, mostly caused by positively hideous abuse by her father and brother. Matthew was the only "steady thing" / "safe thing" in her life, and he defended her many times from bullying from school boys all the way into high school. As a result, she became hell bent on trying to secure her position as his girlfriend so she can get out of her house and get into his. She rapidly mentally declines as more women enter Matthew's life "threatening her love" or so she thought. She is a very sympathetic Yandere, but also the most unstable one in the book. It probably doesn't help that her Spell Core power involves summoning horrifying demons that exist to kill people...
- Evelyn Adams-Nickelsen from Maim de Maim is a maternal variant, as one of the reasons she killed her husband was to keep him from getting custody of her son (the other reason because she felt like it, apparently)
- Euro Spy has the evil Greek villain Nikolai, who is a yandere for Boroka Szabo.
