Doctor Stephen Vincent Strange, better known as Doctor Strange is one of the many heroes of Marvel Comics and the feature hero of his own series Dr. Strange as well as a regular part of The Defenders. He was created by the late Stan Lee and the late Steve Ditko, and first appeared in Strange Tales #110 in July of 1963.
