Fictional character biography:
Stephen Strange was a brilliant but egotistical neurosurgeon who only cared about wealth. However, a car accident damages his hands, shattering the bones. The damage effectively ends his ability to conduct surgery, since his hands then trembled uncontrollably. Too proud to take on a teaching job, Strange desperately began to search for a way to restore his hands, consulting various doctors, homeopathic treatments and traveling around the world to remote regions for exotic cures, all to no avail.
After he exhausts his funds, he becomes homeless, forcing him to perform "back alley" medical procedures for cash. Depressed and still searching, Strange locates a hermit called the Ancient One (who is actually the Earth's Sorcerer Supreme) in the Himalayas. The Ancient One refuses to help Strange because of his selfishness, but senses a good side that he attempts to bring to the surface. He fails, but Strange's goodness appears when he discovers the Ancient One's disciple, Baron Mordo, attempting to kill the old man. After a confrontation with Mordo leads to him being shackled with restraining preventing him from either attacking Mordo or warning the Ancient One, Strange desperately and selflessly accepts the Ancient One's offer to become his apprentice to have some hope of helping the old man. The Ancient One, pleased at Strange's profound change of heart, accepts the westerner and promptly frees him from the restraining spells while explaining he was aware of Mordo's treachery all along. Strange soon Mordo's most enduring enemy, as the Ancient One teaches the doctor the mystic arts.[44] After completing his training, Strange returns to New York and takes up residence within the Sanctum Sanctorum, a townhouse located in Greenwich Village which is guarded by Strange's personal servant Wong.
As the Ancient One's disciple, Strange encounters the entity Nightmare, and other mystical foes before meeting Dormammu, a warlord from an alternate dimension called the "Dark Dimension". Strange is aided by a nameless girl, later called Clea, who is eventually revealed to be Dormammu's niece. When Strange helps a weakened Dormammu drive off the rampaging Mindless Ones and return them to their prison, he is allowed to leave unchallenged.
