The Eye of Agamotto is one of three mystical artifacts made and left behind by the first Sorcerer Supreme Agamotto. Both the Eye of Agamotto and the Orb of Agamotto are passed from the current Sorcerer Supreme to its successor.
The Eye of Agamotto appears to be a sentient object, which confers all it sees upon it's wearer. The most commonly known holder of the eye has been Doctor Strange, who lost the mantle of Sorcerer Supreme when the Eye abandoned him. The suspension was lifted when the Eye of Agamotto bestowed it's power on Brother Voodoo (who was therefore renamed Doctor Voodoo).
Recently Doctor Strange and Hellstorm have been possessed by a being(s) from a different realm who were trying to get the eye as one of the magical artifacts needed to take control of our plane. Doctor Voodoo confronted them but unable to keep the eye secure transported it to Luke Cage in the Avengers Mansion by magical means.
The Eye is used to find and show 'truth.'
- It can emit an 'all-revealing light.'
- It can play back recent events.
- It has other abilities which are similar to telepathy but are magical rather than psionic, greatest of which is the ability to give its user certain mystical perceptions into another's soul.
- It accompanies the wearer's astral form and is one of the few items usable in either state (albeit at a less powerful state).
A 'third eye' often appears on the forehead of the wearer when it is used.
The Eye is used for order or "white" magic only. It does not respond to an evil user's commands, and can only be utilized by a magician of a pure heart and clean soul. However, there has been certain, unclear exceptions, such as when Baron Mordo, when disguised as Strange in a former masked costume he had donned, was capable of wearing both the Eye of Agamotto and the Cloak of Levitation. Strange also worked desperately during the brief conflict to cover the Eye’s gaze, seeming to believe that his impostor could somehow bend his will to the amulet. Mordo uses the Eye to detect the "ethereal vibrations" of the Ancient One in the chamber, even willing it to implant itself upon his forehead. The malevolent Asgardian deity Loki has also worn and used the Eye of Agamotto and the Cloak of Levitation when Thor established his rule over Earth. In the What If? Age of Apocalypse, Nate Summers uses the stolen Eye of Agamotto to create a portal through time to stop Legion, but apparently not even through the magic of the Eye does not automatically bend the rule of diverging timelines, as is shown when, like a cancer, other realities in the Multiverse also become an Age of Apocalypse. The Silver Dagger also was able to steal the Eye of Agamotto after killing Strange.
The Eye can radiate a powerful mystical light that allows Strange to see through all disguises and illusions, even those of Skrulls (before the genetic engineering experiments that shielded them even from the magics of a Sorcerer Supreme), see past events, and track both ethereal and corporeal beings by their psychic or magical emissions. The light given off by the Eye also weakens a variety of evil mystical beings, such as demons, devils, undead beings, dark extra dimensional entities, and even sufficiently corrupt human practitioners of the Dark Arts, as well as used by Strange in the past to achieve nothing more than nothing but mere yet wide and convenient illumination. Strange can use it to probe the minds of others, project a powerful mystical barrier, and create portals to other dimensions. It is also dimensionally linked to the Orb of Agamotto,Clea having used the latter to send Daimon Hellstrom and Power Man through it to Strange's Eye. It has also been used to place beings into Suspended Animation, and Strange has used its light to levitate objects as heavy as the Hulk and Professor Xavier plus his wheelchair together, or the Thing, with minimal effort while simultaneously magically controlling the Cloak of Levitation to fly himself, carrying a total of at least fifteen hundred pounds, during the early years of the Defenders. The Eye of Agamotto can be used to transport a group of dozens of beings of all kinds and power levels into another point within a universe, as Strange did to combat the threat of Thanos. The Eye was used by the Ancient One to banish the demons worshipped by the Devil-Slayer's cult, and appears to be capable of being stolen by them without the Sorcerer Supreme's consent, to be used to unseal a dimensional doorway to the Earth dimension from the demonic dimension; Vera Gemini was able to use the power of the Eye of achieve Xenogenesis in one day whereas the demon overlords achieved it after many eons. The Eye was also used to pierce the veil of the Dark Dimension by opening a portal. The Eye of Agamotto automatically displays to Strange and the New Avengers through its arcane powers in the Quinjet at least thirty-five images of "those who would replace" Strange, suspended in floating and shimmering blue bubbles of light, before the Eye itself vanishes from Strange to the new Sorcerer Supreme. Strange also used the Eye to at least in one instance to project a bolt of pure mystic force (when Strange was confronted by both the Panther and Mantis over the Evil Eye fragment), even when T’Challa had prevented him from uttering invocations or performing gestures, proving that the Eye can be activated by will alone. Strange also joins portions of the combined life essences of himself, Valkyrie, the Hulk and Namor to weave a complex spell through the Eye, which channeled the life energies into a healing glow it bathed upon the dying Nighthawk, healing him. The Eye, on Strange’s command, has been shown to implant itself on the foreheads of other, non-mystical beings and affect them as well, conjuring a psychic illusion making the Hulk and Namor see the other as he is not. The Eye of Agamotto has also been utilized on at least one instance to "reverse the flow of time," causing a broken statue to be reassembled perfectly, though time was only twisted around the statue. Strange uses the Eye of Agamotto to show Nebulon an insight into mankind, mentally displaying to him man’s history, passions and achievements, ultimately dissuading him from further opposing Earth.
