Doctor Strange

Stephen Vincent Strange, simply known as Stephen Strange and Doctor Strange, is one of the major characters from the Marvel comics.

Strange was once a gifted but egotistical surgeon who sought out the Ancient One to heal his hands after they were wounded in a car accident. Instead, the Ancient One trained him to become Master of the Mystic Arts and the Sorcerer Supreme of Earth.

Personality
Morality is explicitly not a factor when a new Sorcerer Supreme is chosen. Nonetheless, Doctor Strange is determined to prevent the station and its associated power from falling into the wrong hands.

Strange stands out as eccentric and decidedly 'other' in the superhero community, from his wardrobe to his house and all its artifacts. People even get nervous when he decides to show up via Astral Projection. In some depictions he seems to enjoy this and find it amusing; in others, it cuts him off from his fellow humans and makes him feel lonely and isolated.

Strange will never give up on a set goal, no matter how much trouble he gets or how deep he falls.

Master Sorcerer
Master of the Mystic Arts, Doctor Strange is one of the most powerful sorcerers in the world. Dr. Strange uses mystical energy invoked upon by spells/incantations or by the power of divine beings to manipulate forces of the universe including projection of mystic energy as bolts, slashes, binds, shields, or a scattered array of energy appearing like electricity, manipulating matter and various energies (physical or spiritual) even transmutation of matter, controlling the elements, opening or sealing mystical portals to other realms, teleportation or dimensional travel, reality warping and control over dimension, seeing through or casting illusions, invisibility and intangibility through astral projection, vast mental powers such as telepathy and telekinesis, communication with the dead and spiritual entities, seeing the future or past, manipulating dreams, removing spirits or placing them back into bodies, summoning supernatural beings, or using the powers of supernatural items.

Many of Doctor Strange’s powers are a function of his ability to manipulate the ambient mystical energy of the Marvel Universe. With this ability Dr. Strange can perform many functions. Commonly this is seen as energy attacks that range from low power to planet destroying, transmutation, telekinesis, teleportation, protective shields, etc. He uses this mystical energy to cast spells of a near infinite variety.

Dr. Strange can also channel the virtually unlimited energy of nigh-omnipotent mystical and non-mystical beings--known as Principalities--to empower his spells. This can take the form of stating what he wants to occur. This ability to be a conduit to multi-versal power sources has given rise to the phrase "Dr. Strange is as powerful as the god he invokes". He is quite capable of utilizing power that is considered "black magic", though he tends to do so only under extreme exigency. Though he rarely has, he can absorb the power of even a cosmic or semi-deity entity. Doctor Strange has a pact with Eternity possibly allowing him to live as long as the Ancient One and others before him have.

In addition to Cyttorak and Oshtur, among the beings of power called upon by Strange are all-seeing Agamotto and hoary Hoggoth, who along with Oshtur form the triad known as the eternal Vishanti; the Seraphim; Cthon (who created the Darkhold tome); Gaia; Ikonn; Dormammu (rarely) and the hell-lord Satannish. Sometimes it appears the substance of mystical realms is invoked rather than the beings who rule over them, as when Strange summons the Flames of the Faltine (the birthplace dimension of Dormammu, but also particular energy beings who rule there). This may explain why Strange is able to call upon such evil entities as Cthon and Satannish to power certain spells, yet not be in their service.

Certain beings are typically invoked for particular effects, such as Ikonn for illusions, the Seraphim for protective effects like shields and the like, Cyttorak for bindings, Agamotto for dispelling negativity and revealing the truth, etc. Other magical constructs commonly employed through such agencies are the Vapors of Valtoor, the Chains of Krakkan, and the Seven Suns of Cinnibus. Doctor Strange seems to be more so than anyone else under the favored patronage of the powerful Vishanti.

Magical Artifacts
The Sorcerer Supreme possesses a formidable arsenal of magical artifacts, two of which are particularly recognizable-- the Eye of Agamotto and the Cloak of Levitation. The Eye of Agamotto is an artifact with many uses, such as vastly extending Dr. Strange's psychic abilities, inter dimensional travel, emitting a light that pierces all deception and is anathema to evil beings, serving as a protective talisman, and other feats. It can be used as an almost irresistible offensive weapon, though Strange rarely does so. Similar to Mjolnir, the Eye can only be used by those it deems as morally worthy. The Cloak of Levitation has been a third set of hands for Dr. Strange, responding to his thoughts to entangle opponents, and allowing him to fly and levitate. It is virtually indestructible and has shielded him from attacks as well.

Strange also possesses the Orb of Agamotto, a sort of hyper-powerful crystal ball that allows clairvoyant perception of anywhere in any dimension or realm. Other powerful artifacts in his possession include the Book of the Vishanti, the Darkhold tome, and the Wand of Watoomb. His abode in Greenwich Village known as the Sanctum Sanctorum, both defies normal spatial law and is of such magical potency in its protections that it may be considered an artifact itself. Doctor Strange has recently also come into the possession of the Soul Gem.

Trivia

 * In some depictions he was prone to alcohol abuse as a surgeon, either during or just after the car accident that ruined his hands.
 * Was visually based on Vincent Price. It's been pointed out by several characters, and eventually it's revealed that his middle name is "Vincent".
 * At his most powerful, Strange is, by ridiculously far,  the  most powerful of all mainstream heroes in the Marvel Universe, such that even the likes of The Mighty Thor or the Silver Surfer would be no match whatsoever for him in a straight fight. He needs to be, since his enemies are often far more powerful than even that.
