History Yandere / LiveActionTV

* ''Series/MidsomerMurders'': In "[[Recap/MidsomerMurdersS3E1 Death of a Stranger]]", Grahame Tranter ends up disturbingly close to this, though he ultimately can't go through with it and ends up DrivenToSuicide instead.

** Masato Kusaka in ''Series/KamenRiderFaiz'' is a rare male example of this. He replaces the "cute, delicate, and sweet" facade with one that is strong, [[TheAce supremely competent]] and [[{{Bishonen}} handsome]], but his inner obsession with Mari fits this exactly. Taken to the extreme in the non-canon novel where [[spoiler:he goes as far as to ''rape'' her]].

** In ''Series/KamenRiderFourze'', Makise/Pyxis Zodiarts tried to use his powers to force girls to be with him, eventually trying to send several girls plummeting off a cliff to their deaths because they rejected him.
** Jiro in ''Series/KamenRiderKiva'' is obsessed with Yuri, whom he sees as his only hope of reviving the Wolfen race. He tries to kill Otoya as a rival for Yuri; then tries to [[IfICantHaveYou kill Yuri too]] because she refuses to marry him.

* ''Series/TheWalkingDead'' has Shane. [[spoiler:When Rick does find his family, Shane slowly goes insane, and convinces himself that Rick isn't fit for being a good enough husband or father to them, and that he's just 'getting in the way'. He even goes so AxCrazy to the point of [[MurderTheHypotenuse trying to murder him]]]].

* ''Series/{{You}}'':

* ''Series/InterviewWithTheVampire2022'': As a romantic partner, Lestat de Lioncourt is a toxic cocktail of StalkerWithACrush, CrazyJealousGuy, GreenEyedMonster, DomesticAbuser and MurderTheHypotenuse. As Creator/SamReid elucidates in [[https://www.youtube.com/watch?v=Fa0c43yIVpw this interview:]]

%%* Annika in the third season of ''Series/BronBroen''. Extra creepy because she works as an {{undertaker}}.

* ''Franchise/PowerRangers'':
** Divatox is one towards Malagor as she tried to sacrifice Kimberly, the original Pink Ranger, and Jason, the original red/gold Zeo Ranger. [[spoiler:After Malagor was destroyed, she swore revenge on the Power Rangers.]]

* In ''Series/SonsOfAnarchy'' ATF Agent Joshua Kohn follows Dr. Tara from Chicago to Charming and engages in increasingly disturbing StalkerWithACrush behavior culminating [[spoiler:in an attempted rape/abduction that ends with his death]].

* ''Series/StargateSG1''
** Reese in the episode "Menace" seems like a sweet, friendly (if a little spoiled) RobotGirl, but when things don't go her way with Daniel, she [[spoiler:creates an army of Replicators which proceed to nearly wipe out the SGC]].

* ''Series/LawAndOrderSVU'':

* More than one of these [[ADeathInTheLimelight meets their end]] in ''Series/OneThousandWaysToDie''. The most obvious example is Ashley from "Smoke-stalked", who tried to break into the home that the dude she stalked shared with his wife... only to end up spending a week stuck in the chimney since they weren't even there. [[AndIMustScream She slowly died of a mix of starvation, dehydration, and suffocation]]; the other two only found out when they tried to unclog their chimney.
* In ''Series/TheOuterLimits1995'', there's RobotGirl Valerie in the season 1 episode "Valerie 23". Made to care for the disabled, she begins a relationship with one of her patients. When said patient starts falling in love with a human woman, she goes all out psycho trying to MurderTheHypotenuse. Suffice it to say these are NOT ThreeLawsCompliant.

* ''Series/PersonOfInterest:'' Root, who is obsessed with ''The Machine'' as well as to its creator Harold Finch. When she gets into a quasi-relationship with Shaw, she also shows this tendency as well, casually threatening the life of the man Shaw is on a not quite date with.

* ''Series/{{Revenge}}'':

** In "The Conscience of the King", the yandere is the daughter of a semi-repentant war criminal on the lam; she travels through the universe with him, acting with him in Shakespeare plays while killing witnesses to her father's wrongdoing. [[BreadEggsMilkSquick She's cute. She's sweet. She's 17. She's killed almost a dozen]].
** In, "Whom Gods Destroy", an Orion Female mental hospital patient named Marta claims that her reason for attempting to kill Captain Kirk was that she loved him.

* [[Recap/TalesFromTheCryptS1E5LoverComeHackToMe An episode]] of ''Series/TalesFromTheCrypt'' had a couple getting married and sharing a perfect night of passion. Immediately afterward, the woman murders the man to make sure time doesn't spoil their love.

* ''Series/InterviewWithTheVampire2022'': The fifth episode demonstrates a violent version when Lestat's volatile mind ''snaps'' after Claudia declares that she came back home to bring Louis on her trip to Europe. [[DomesticAbuse Lestat then brutalizes Louis]] and drains part of his blood to weaken his lover even further so that Louis can't physically go anywhere.

** "Conned" features a female PsychoPsychologist who fell in love with a teenage client and sexually took advantage of him. When she eventually became pregnant she tried to manipulate him into staying with her by using his abandonment issues against him. When he finally tried to leave her for a girl his own age she called her parents saying he was a rapist, then intentionally misdiagnosed him with schizophrenia so she could keep him drugged up in an institution. When he escaped, she pretended to work with detectives to "rescue" him so she could get him back.

* The episode "Bedtime" from ''Series/LawAndOrderSVU'' featured a female police officer who fell in love with a mattress salesman. When he didn't leave his wife quickly enough, [[MurderTheHypotenuse she killed her]], convinced him that he was going down for the murder, then faked his death and kept him trapped in her apartment for 35 years.

When he escaped, she pretended to work with detectives to "rescue" him so she could get him back.

* ''Series/MurderSheWrote'' has this every now and then.
** In "The Sins of Castle Cove," [[spoiler:Elis the bookkeeper was obsessed with Miriam, the murder victim. He believed that she had feelings for him even though she was married and was clearly not interested in him at all. When he read the titular book and found the section that revealed her true feelings for him, he confronted her, hoping that he was mistaken. Unable to cope with the bitter reality, he [[IfICantHaveYou struck her down]] out of anger. When he's revealed as the murderer, he even says, "She should have loved me! I loved her so much!"]]

* Chris Keller in ''Series/{{Oz}}'' over Beecher. He kills every guy that Beecher sleeps with and the guy who murdered Beecher's father, has Beecher murder Schillinger unknowingly, acts overly aggressive with him at times, on two occasions has knocked him out with a blow to the head when Beecher goes against his wishes and later handcuffs him to a chair away from other people where he forces a kiss on him, and finally murders the Aryans so that they don't pose a threat to him or Beecher anymore.
** As well as Ryan over Dr. Nathan. After she helped him through cancer, he immediately divorces his wife. Later, he [[ForcefulKiss forced a kiss on her]], paid a fellow inmate to steal her stethoscope, and when she started ignoring him, had his brother Cyril [[MurderTheHypotenuse kill her husband]]. After she was raped, he very quickly murdered the man that did it. It was even said outright that his love for her was more of an unhealthy obsession. However, Dr. Nathan actually falls for him in the end.

** Miss McMartin, the social worker in charge of Walden's adoption of Louis, seems like a nice, reasonable woman at first. Then Alan breaks up with her and she becomes a raging, vindictive lunatic who threatens to take Louis away. Walden ends up sleeping with her to prevent this, and she more or less calms down, though she mentions she stole and froze his sperm. This aspect of her character pretty much vanishes afterwards.

* WWE has done this on more than one occasion, including one storyline when Mickie James was introduced as Trish Stratus' biggest fan. Her [[LoonyFan obsession increased]] until Trish couldn't take it any more. This resulted in Mickie turning on her beloved.
** [[Wrestling/ChickBusters AJ Lee]] is the most high-profile recent example of this trope in action in WWE since, as the targets of her... "interest" are the WWE Champion (her most recent crush) and his challenger (her ex).

* In season 2 of ''Series/{{Hannibal}}'', [[StalkerWithACrush Hannibal Lecter]] serves as this to Will Graham. [[spoiler:After framing Will for his murders, Hannibal continues to visit Will at the psychiatric institution and involve himself in Will's trial]]. He's clearly obsessed with Will, talking about him endlessly with Jack, Bedelia, and Chilton. "Hassun" implies that his killings and machinations are depraved attempts to express love for Will. His love for Will only deepens in season 3, which worsens his more spiteful, possessive tendencies. He leaves a "valentine from a broken man" for Will in the form of a corpse wrapped into a heart, takes Will captive in Italy and attempts to cut open his skull to eat his brain, and saves him from Mason's wrath (carrying him in almost the exact way another Hannibal Lecter did his love interest). Hannibal then proceeds to give himself up to the FBI, potentially being put away for life, ''[[CrazyJealousGuy just so that he can get back at Will for rejecting him]]''. He also attempts having Will's wife and step-son killed by another killer, just to get Will's attention.

* Miss Piggy from ''Series/TheMuppetShow'' is an obvious one. Rather animesque in that, though she often randomly attacks everyone over [[RantInducingSlight any minor thing]], the one who she is ''really'' most likely to [[MegatonPunch Falcon Punch]] across the room is her "Kermie".

* Rose [[StalkerWithACrush stalks Charlie]] in ''Series/TwoAndAHalfMen'' and is just unbalanced enough that she could very well boil a bunny. She later implied that she ''[[IfICantHaveYou purposely shoved Charlie in front of an oncoming train]]'' [[IfICantHaveYou not long after she caught him cheating on her with another woman]].

** Protagonist Joe pretends to be a charming NiceGuy towards his target, but is in fact a murderous stalker who wants to "save" his love from anyone who stands in their way. Usually by killing them. As shown in the season one finale, [[spoiler:he is even willing to kill his object of affection once they reject him, [[HereWeGoAgain only to quickly moves into someone else]].]]

* An episode of ''Series/TalesFromTheCrypt'' had a couple getting married and sharing a perfect night of passion. Immediately afterward, the woman murders the man to make sure time doesn't spoil their love.
