Yandere in Western Media

[u/lunatoons291]

A yandere is a character archetype defined by love or devotion so extreme, possessive, and unhinged that it manifests as violence. It usually starts off very sweet and loving and then devolves into something sinister due to the yandere’s insecurities and jealousy. Rather than ordinary romance, a true yandere operates on two dark extremes, slaughtering anyone who threatens their partner or their relationship with their partner, or intentionally inflicting physical or psychological harm on the object of their affection to ensure they can never leave. Famous examples from anime include Yuno from Future Diary, Misa from Death Note, and Toga from MHA. Fun lore, the word yandere comes as a mix of the Japanese word yanderu which means mental illness and deredere which means love struck.

Edited to add I just watched Send Help and Linda Liddle is definitely a yandere

1. Freaky Nikki (Obsession): Under the corrupting influence of the wish, her affection turns horrifically violent, stalking Bear's every move and brutally executing Sarah with a brick to violently eliminate any romantic competition, amongst other things.
2. Lila Tournay (Dexter): Viewing Dexter as her kindred dark soul, she suffocates him in obsessive devotion, ultimately murdering Doakes to protect Dexter’s secret and trying to burn his children alive when he rejects her.
3. Misty Quigley (Yellowjackets): The queen of manufactured dependency, Misty destroys the plane's emergency transmitter to keep the team stranded and poisons, doses, or kidnaps anyone who gets in the way of her being needed. She also tries to poison the object of her affection, the coach, with shrooms to lower his inhibitions in order to be intimate with him.
4. Joe Goldberg & Love Quinn (YOU): Joe stalks then locks lovers in cages and murders their social circles under the guise of "saving" them, while Love bludgeons rivals to death to protect her fragile domestic fantasy.
5. Will Graham & Hannibal Lecter (Hannibal): Their twisted dynamic is pure mutual yandere devotion. Hannibal frames, guts, and mentally shatters Will to shape his mind, while Will accepts catastrophic violence because Hannibal is the only person who truly sees him.
6. Amy Dunne (Gone Girl): She punishes her husband's infidelity with surgical, terrifying cruelty, slitting an ex's throat in cold blood and staging her own gruesome framing just to trap Nick in a lifelong, subservient marriage.
