The character's origin story relates that he was once a brilliant but egotistical surgeon. After a car accident severely damages his hands and hinders his ability to perform surgery, he searches the globe for a way to repair them and encounters the Ancient One. After becoming one of the old Sorcerer Supreme's students, he becomes a practitioner of both the mystical arts as well as martial arts. Along with knowing many powerful spells, he has a costume with two mystical objects—the Cloak of Levitation and Eye of Agamotto—which give him added powers. Strange is aided along the way by his friend and valet, Wong, and a large assortment of mystical objects. He takes up residence in a mansion called the Sanctum Sanctorum, located in New York City. Later, Strange takes the title of Sorcerer Supreme.
