In Yu-Gi-Oh! GX, Dark Magician Girl appears as a Duel Spirit during the Duel Festival. On the one day Duel Spirits can take physical form, the Dark Magician Girl surfaces during a school-wide festival to duel with Jaden Yuki after finding out that Syrus Truesdale had planned a Costume Duel for that day. After Jaden laments that he has no one to duel once Alexis Rhodes chases off her brother for taking a picture of her in costume and trying to send it to their family, the Dark Magician Girl shows up and tells Jaden that he can have a duel with her. With the exceptions of Jaden, Syrus, and Chazz Princeton, nobody thought that she was the real Dark Magician Girl because everyone was in Duel Monsters costumes. Syrus harbors feelings for her, and Jaden considers her a formidable opponent. Bastion Misawa pointed that Dark Magician Girl should have been in Yugi Muto's Deck. The crowd cheered actively for her, and even though she lost, she didn't care because she had so much fun. Before the day ended, she used the last of her energy to give Syrus a kiss on the cheek and then she went back into her card.
