Stephen Strange was a brilliant neurosurgeon, but his arrogant, selfish and greedy persona made him unpopular. When he suffered a car accident that damaged the nerves of his hands preventing him from work as a medical surgeon, he exhausted his fortune in trying to heal himself. With his last resources, he went to the East in search of an old wizard called ”The Ancient One” and ended up becoming his apprentice in the mystical arts. Strange became the Sorcerer Supreme on Earth, establishing his base in the Sanctum Sanctorum in Greenwich Village, New York where he fights supernatural forces next to his friend Wong.
After being turned to dust by Thanos in Avengers:Infinity War, Doctor Strange was snapped back by the Hulk and brought everyone back to battle with his power.
