In the Ultimate Marvel continuity, Professor Charles Xavier is the world's most powerful telepath, the founder and patron of the X-Men and a world-famous lecturer for pacifism and mutant emancipation. In contrast to his mainstream version, he is publicly open about his mutant status from the beginning and also has limited telekinetic abilities. He leaves his wife Moira MacTaggert, whom he collaborated with to create new therapies and surgical techniques for their mutant patients, and their sick son David to pursue Magneto's dream of a mutant society, but Magneto turns on him, crippling him with a shard of metal through his spine.
