- This is becoming something of a staple for Abridged Series.
- Dragon Ball Z Abridged: depicts Chichi this way, though to be fair she was sort of like this in the actual series as well (though it was Played for Laughs there).
- Final Fantasy VII: Machinabridged depicts Aerith as being extremely passive-aggressive towards any female - regardless of age, romantic interest, or species - who acknowledges Cloud's existence, or whom Cloud takes note of. This starts going into Yandere territory in episode 14, when she 'accidentally' destroys the Shiva Materianote , just because Cloud remarked on how beautiful the summoned goddess is.
- Avatar: The Abridged Series makes one out of the one-off character Meng.
- Sword Art Online Abridged amplifies Asuna's canonical clingy moments to the point where, after Lisbeth has an episode of Unresolved Sexual Tension with Kirito, Asuna gives the other girl a fake hug and softly, calmly explains that "If I see you try something like that again, I WILL come for you." Then at the end of episode, after Lisbeth has run off crying and Kirito finds and comforts her, the blacksmith returns to her shop to find it a charred ruin, with "YOU WERE WARNED" scrawled on the sign. Liz spends the rest of the series terrified of Asuna, to the point of diving out of windows to get away from her.
- Cracked noted in this article that the behavior of a woman who might follow Cosmo's suggestions on intimate relationships could very well end up acting like this. The suggestions are downright possessive, obsessive, and overall psychotic. Everything from feeding a boyfriend laxative to crushing his testicles... all over perceived and potentially groundless possibilities of infidelity. At no point did any of the suggestions involve leaving the boyfriend; it was all about punishing them.
- Shannon in the TV Tropes webseries Echo Chamber obsesses over Tom, stalks him, and threatens girls he is seen with. She scares Tom enough that he agreed to propose to her, because he was worried she would severely hurt him if he didn't.
- Ashley and Vanessa in The Fabulous Life of Bratz. Doesn't help that they're going after the same guy either.
- Its Just Some Random Guy: Random Gal, his girlfriend and production designer.. Just... watch.
- BriTANicK shows us how it's done with "The Kiss."
- A gay example in Miller from the third volume of Yotam Perel's Nameless series, who falls for Chocolate Man."I will murder him with my knives for you."
- The character of Rift from New Vindicators seems like your usual young teacher/superhero until her obsession with Michuru comes out. Then people start dying.
- Split-minded Vasto Lorde En from a certain RP game is this way towards the protagonist. "hOW dO YOu do iT? stay so RIGHT wiTh So mAnY. so BeAutiFul."
- Shadow Unit: Betty Johnson, the gamma of "Always Crashing in the Same Car." The crazy seems to have started because while she was pregnant, she walked in on her husband raping and killing a woman and subsequently miscarried. The first manifestation of her gamma powers was mind-controlling her husband into killing himself; every year since, she finds a man with the same name and mind-controls him into believing he's her husband. Then she commands him to kill himself on the anniversary of her first husband's death. Most of the episode is from her perspective, through letters she wrote to Reyes; she not only seems to believe that all the Tom Johnsons she married were actually the same man, but she insists to the end, even after being arrested and sent to Idlewood, that "our love is forever".
- The Creepypasta Cloak and Dagger, in which a girl (probably) steps out in front of her crush's girlfriend's car, killing her when she swerves out of the road.
- Survival of the Fittest:
- Zachariah Johnston from TV1. He started out as an Adorkable kid with autism who happened to have a crush on Mae St. Clair. However, he becomes jealous of Shawn Morrison (the other part of the Love Triangle), and has flat out attacked other characters who he thinks will hurt her or steal her away, most notably Harold Smythe.
- Robin Pounds from Program v2 becomes incensed when Shawn Bowe-Crooke abandons her, and tracks him down specifically to destroy him and everything he loves.
- After being friendly with her for most of their crossover review, The Nostalgia Chick tries to stab Obscurus Lupa after she finds out she's the one who Todd in the Shadows has a crush on.
- SCP-962 is a giant steel tower that wants to help the "great ones" (humans) by mutilating, enslaving, and/or killing every non-human organism in the area around it. It also sends us "high quality" poetry.
- With just a few simple tips, you too can have a boyfriend! Remember to be persistent!
- Doki from There she is!! starts as a fairly minor example of this: She does chase Nabi around the city and can't take "No" for an answer, but otherwise doesn't seem to be all that crazy or violent. Her love craziness reaches its apex midway to Step 3, until she becomes saner, but only after Nabi agrees to become her boyfriend.
- While it could be seen this way, keep in mind, "There She Is" is all about showing Nabi and Doki's relationship in a condensed form. It can also be interpreted that Doki's trying to chain away Nabi's social qualms with their relationship, as can be seen in the later steps.
- "I'm sorry to god for what i have done. I love my family so I kill all my family. It's the only thing I can do to stay together with them F O R E V E R!"
- Annabelle Wynters from Under the Van Gogh, though perhaps as a direct cause of Love Makes You Evil, Love Makes You Crazy, and some Manipulative Bastardry.
- Kaorin from Yukari Is Free, because Sakaki's with Kagura and not her.
