Arcane (Season 2): Jinx

She was an Zaunite orphan after her parents (Felica and Connol) were killed in the war between Piltover and Zaun during her childhood along with her big sister, Vi. She was taken in by the Lanes' protector, Vander, but even after that, she was being taken in Silco which led her to her corruption as she gotten older turning her into a nihilistic anarchist, completely rejecting her nicer, shy, former identity and past in favor of her new moniker and wild side. This is from Episode 8 where Vi confronts Caitlyn about Jinx's arrest for her missile attack at the Piltover council; leading to the death of 3 councilors: Cassandra Kiramman, Irius Bolbok and Torman Hoskel. During her time in her jail cell, she started to hallucinate Silco, who urges her to escape the cycle of violence. When Vi visits her cell, Jinx locked her in, determined to "break the cycle of violence."
