Doctor Strange is a practicing magician who draws his powers from mystical entities such as Agamotto, Cyttorak, Ikonn, Oshtur, Raggadorr, and Watoomb, who lend their energies for spells. Strange also wields mystical artifacts including the Cloak of Levitation which enables him to fly; the Eye of Agamotto, an amulet whose light is used to negate evil magic; the Book of the Vishanti, a grimoire which contains knowledge of white magic; and the Orb of Agamotto, a crystal ball which is used for clairvoyance.
In addition to his magical abilities, Strange is trained in several martial arts disciplines, and has shown proficiency with numerous magically conjured weapons including swords and axes. Strange was a skilled neurosurgeon before nerve damage impaired his hands.
Doctor Strange is described as “the mightiest magician in the cosmos” and “more powerful by far than any of your fellow humanoids” by Eternity, the sentience of the Marvel Universe. He holds the title of Sorcerer Supreme from 1973 (with the death of the Ancient One) to the present, except during an interruption from 1992 to 1995. He relinquishes the title once again in 2009, but reclaims it in 2012 when he proves himself willing to protect the world even without the title.
