Throughout much of the character's history in comics, Xavier is a paraplegic using either a wheelchair or a modified version of one. One of the world's most powerful mutant telepaths, Xavier is a scientific genius and a leading authority in genetics. Furthermore, he has shown noteworthy talents in devising equipment to greatly enhance psionic powers. Xavier is perhaps best-known in this regard for the creation of a device called Cerebro, a technology that serves to detect and track those individuals possessing the mutant gene, at the same time greatly expanding the gifts of those with existing psionic abilities.
