first appears in a flashback, with Stewart digitally de-aged, when he and Magneto pick up a young Jean Grey as their first student. He is given a more youthful appearance using visual effects. In the present, Xavier expresses worry over Cyclops' grief over Jean's death and tells Storm that should anything happen to him, she would replace him as the head of the school. When Jean is discovered alive, Xavier sedates her and tells Wolverine that he had kept her powers in check with mental barriers since she was a child, resulting in her developing a second personality known as "The Phoenix."

On the DVD Commentary, it is revealed that the body on Muir Island is someone
