- Eboli for Don Carlo.
- In Avenue Q Christmas Eve is usually a Tsundere but in "The more you ruv someone" there are lines which depict her as a possessive type 3.
- Don José, for Carmen - it starts with him going to jail for her - and keeping the flower she game him the whole time. He comes back and joins her group, but he can't deal with how she flirts with other guys. He picks a knife fight with her new lover - a bullfighter - over her, and when she's sent him away for good, he meets her outside of the arena and kills her.
- Abigail Williams from The Crucible fits this trope like a glove. After her boss John Proctor ends their affair, Abigail jumps at the opportunity to have his wife Elizabeth arrested and executed for witchcraft. It backfires big time. Elizabeth's pregnancy keeps her from being executed; John takes the blame upon himself and chooses execution over admitting witchcraft and losing his land, which would leave his family homeless.
- Donna Elvira for Don Giovanni. She gets better.
- Brünhilde for Siegfried, in Goetterdaemmerung.
- Hamilton casts King George III of England this way. You'll Be Back could be a yandere anthem:
I will kill your friends and family to remind you of my love.
- Heathers has J.D. to Veronica. They actually managed to ramp it up from the movie. Check out these lyrics from the song "Meant to Be Yours:"
You chucked me out like I was trash,for that you should be dead.But, but, but!Then it hit me like a flash;What if high school went away instead?Those assholes are the key,they're keeping you away from me.They made you blind,messed up your mind,but I can set you free!
- Jackie-O from The House of Yes. She kills her twin brother, whom with she has been having an incestuous relationship for most of their lives, when he attempts to regain a life of normalcy with his utterly average fiancee.
- Nessarose from Wicked is this only for the musical. She developed feelings for Boq when he decided to talk to her during the dance. He certainly didn't help his situation by telling her that she was beautiful in an attempt to make it less obvious that he's there because he felt bad for her. That and he was doing it because Galinda asked him. Over the years, Nessa ruled over the Munchkins and had restricted their rights because of Boq. Once her sister granted her the ability to walk, he thinks that she no longer needs him and decides to try leaving her for Galinda. Her response is to use Elphaba's magic book to try making him hers. Unfortunately, she shrinks his heart and Elphaba is forced to give him a tin form so that he doesn't die.
- The titular character of Miss Julie. She has a destructive crush on her driver, and uses her power to push him about, teasing him, playing with him, until circumstances get out of control.
- Bluebeard, for Judith and all the other women he kills and keeps forever.

- Canio from Pagliacci learns that his wife Nedda is cheating on him, and loses it. At first, the audience thinks he's giving a very emotional performance, but soon realize this is for real. Canio kills Nedda and Silvano and gives a Bond One-Liner.
- The Phantom of the Opera: Erik, the eponymous Phantom, towards Christine. Erik captures Christine's lover and gives her the choice of being with Erik forever or watching her lover die. Ultimately subverted as, when Christine does choose Erik, he realizes that he can't force her to love him and lets her go.
- In the theatrical sequel Love Never Dies, Meg Giry has become one: she has fallen in love with the Phantom, now her employer at a pierside show in Coney Island, New York. When she sees how much he still loves Christine, Meg goes insane and kidnaps Christine's son, leading to a rather ... explosive finale.
- Lucy from 13 is a milder version of this trope. She looks like your Average Self-Concious Teengage Girl, but just mention Brett and she becomes Clingy Manipulative and Bitchy. She may not be willing to murder, but she is willing to ruin a few social lives.
- Depending on the interpretation, The Governess from The Turn of the Screw. This only works in the interpretation where The Governess is insane, the ghosts are not real, and she has the hots for Miles, killing him to protect him from corruption.
- Andrea, in one of the skits of Voices From the High School.
"Yeah, I know. the jerk's waiting. So go. I haven't got a gun. Yet."
- The title character of Wozzeck, for Marie.
- Salome, the Princess of Judea at the time of Jesus, is this toward Jokanaan (John the Baptist) in both Oscar Wilde's play Salome and Richard Strauss's opera adaptation. Whenever she's around Jokanaan she can't stop saying "I want to kiss your lips!" When he, predictably, wants nothing to do with her so long as she remains uninterested in Christianity, she uses a seductive dance to trick her stepfather, Herod, into giving her "anything she wants," which ends up being Jokanaan's severed head on a plate.
