jean grey appears in "marvel anime: x-men", voiced by yurika hino in japanese and again by jennifer hale in the english dub. at the beginning of the series, she is consumed by the phoenix force and nearly destroys the world with her tremendous strength and power. the x-men engage in a brief battle with her, until she ultimately sacrifices herself to save the world. although she apparently dies, she assists the x-men with conflicts through a strong telepathic link in later episodes, such as saving professor x from hallucinations, and appears as the white phoenix of the crown, encouraging the x-men to keep on fighting to save the world. she was in a strong and close romantic relationship with cyclops, and had a necklace with a ruby stone with gold in the shape of a phoenix, which was a gift from cyclops. the necklace was then given to hisako as a sign that cyclops can finally let jean go, as he recognizes her sacrifice as a symbol of love for her friends and the world. her dark phoenix persona is taken from "x-men: the last stand" where her face is full of dark veins and her eyes become entirely black.
