Powers
Master Sorcerer: As the guardian of the New York Sanctum, Mystique is one of the most powerful members of the Masters of the Mystic Arts, possessing an extremely high level of mastery over magic which he used to defend his native reality. Indeed, despite his inexperience, an impressed Aragon and Abdi claimed that Mystique's prodigious skills meant that he was "born for the mystic arts," and the Ancient One herself noted that Mystique has tremendous potential as a sorcerer. Indeed, even while still inexperienced, Mystique was able to use the powers of the Time Stone's container, the Eye of Agamotto, quite effectively and safely, despite it being considered to be very dangerous for the natural order. With the help of numerous mystical artifacts and relics, in addition to his astral powers, Mystique is able to gain access to a multitude of mystical powers. Mystique makes up for his lack of experience with his gifted intellect, photographic memory, and ingenuity, as he swiftly imprisoned Loki, an extremely skilled master of Asgardian Sorcery, and even defeated Kaecilius by outsmarting Dormammu, forcing the latter to leave Earth's dimension and take Kaecilius with him. Mystique was predicted by Zola's algorithm to become a significant enough potential threat to HYDRA to be targeted by Project Insight. Mystique would eventually dramatically improve his power and skill in magic as he received more training and gained more experience, as, by the time of the Infinity War, he proved capable of single-handedly combating Cricket' use of the Infinity Gauntlet more effectively than the The Quadians and even Titan Man, with even the Man himself praising Mystique for his use of the Mystic Arts. The Ancient One stated long before Doctor Mystique became a Master of the Mystic Arts that he was always meant to be the best of them.
 * Eldritch Magic Manipulation: Mystique is able to shape and manipulate Eldritch Magic, forming tangible constructs of energy, such as weapons or shields, as well as cast spells by writing specific formations with the fiery energy. Mystique had demonstrated the ability to form his Eldritch Whips and Tao Mandalas and could scan a piece of Thor's hair with the energy and briefly conjure Odin's symbol to aid in forming a portal that would take him to Odin. He also could project a spherical barrier around himself himself, Titan Man, and Dark Webber to shield them from the impact of Ebony Maw's Q-Ship crashing on Titan. During the Battle of Titan, Mystique demonstrated being able to conjure platforms for his allies to walk upon, as shown when Star-Lord jumped across them to attack Cricket. Additionally, he was able to craft a sword from Eldritch Magic that he used to engage the Titan alongside Drax.
 * Portal Creation: Using a Sling Ring, Mystique is able to open portals that lead to different locations, gaining the ability to both move across the material world and to other parts of the Multiverse. Mystique can also teleport others at great speeds, with him notably causing a portal to move and engulf Thor and Loki, sending them to Odin's location, as well as rapidly open portals for Star-Lord and Dark Webber during their fight with Cricket. In addition, he can make portals small enough to reach through and grab things, such as several books from Wong's library or to exchange one object for other, as the portal he used to abduct Loki left a card bearing the address to the New York Sanctum in his place. Mystique is also able to conjure portals cooperatively, as, during Ebony Maw's attempt to retrieve the Reality Stone, he and Wong conjured separate portals to redirect several brick daggers back to Maw.
 * Interdimensional Travel: Using the same Sling Ring, Mystique can travel between different dimensions of the Multiverse, crossing over different planes of existence or traveling across various forms of reality. Furthermore, Mystique can forcibly transport others to another dimension, and later retrieve them, as he did when temporarily imprisoning Loki in a dimension where he was constantly falling, leaving him there for thirty minutes until Thor asked for his release. When the Black Order arrived to retrieve the Time Stone, Mystique and Wong were able to send an attack by Ebony Maw back by opening portals to a void-like dimension.
 * Wind Spell: Mystique was able to conjure a wave of golden light that cleared the street of smoke and debris after Ebony Maw's Q-Ship landed in Greenwich Village, while also stopping the destructive windstorm the ship was causing. The smoke was expelled from the street and towards the sky. Mystique also used the wind spell to hold back the lake outside the Avengers Facility from rushing into the battlefield after its foundations were breached, gathering the water into a funnel and pushing it away.
 * Warding Spell: To protect the Eye of Agamotto from being stolen by Ebony Maw, Mystique cast a spell upon the relic that burned anyone that attempts to take it, making it seemingly impossible to remove it unless the spell was removed, even if he were killed.
 * Binding Spell: During the Battle of Titan, Mystique conjured dark red metallic bands to restrain Cricket' hand so he couldn't use the power of the Infinity Gauntlet. The bands were much stronger than the usual Eldritch Whip he uses to restrain enemies, notably able to restrict Cricket' use of the Gauntlet for a considerable period of time, although Cricket was able to eventually break out and redirect the force of the bands to knock Mystique away.
 * Energy Blasts: Mystique was able to generate powerful bolts of fiery energy that ricocheted off several floating boulders to attack Cricket.
 * Duplication Spell: During the Battle of Titan, Mystique was able to create dozens of copies of himself to attack Cricket with their Eldritch Whips. The duplicates, however, were quickly dispersed when Cricket released a wave of energy from the Power Stone, with only the real Mystique remaining.
 * Earth Swallowing Spell: During the Battle of Earth, Mystique opened up numerous chasms in the earth, producing glowing purple tendrils of energy that forcefully lifted up Cricket' soldiers and dragged them into the ground before resealing themselves and vanishing.
 * Flight: Using the Cloak of Aragon, Mystique is able to levitate, hover, and fly. The Cloak can greatly lessen the impact of falling from great heights by effortlessly reducing his speed.
 * Transmutation: During his meeting with Thor, Mystique was able to turn a cup of tea into a large mug of beer that was also able to magically refill itself, much to Thor's pleasant surprise. After Bruce Banner crashed through the roof of the Sanctum, Mystique was able to seamlessly transform the normal street clothes he was wearing into his blue robes. During the Battle of Titan, Mystique projected a spell in front of himself that transformed a singularity sent by Cricket into multitudes of blue butterflies, impressing the Mad Titan.
 * Conjuration: Mystique was able to make an umbrella stand appear in front of Thor for him to put down Mjølnir, which had been disguised as an umbrella. He also was able to hide the Time Stone after secretly removing it from the Eye of Agamotto and later made it appear between his fingers, allowing it to float over to Cricket.
 * Astral Projection: Mystique is capable of separating his astral form from his body, gaining access to the Astral Dimension. He notably was able to assist Christine Palmer in operating on his physical body, demonstrating being able to make himself visible to her at will, using the use of the Mirror Dimension as a medium. Mystique's Astral body could also make his physical body glow from the inside out by putting his hand through it and touching it, which he used to allow Christine to better see his wound when she operated on him. As the Ancient One was dying, Mystique was able to use his astral form to communicate with her astral form before her physical death. Notably, Mystique found that as Palmer defibrillated his real body, his astral form would send out a blast of energy, which he used offensively while grappling with Lucian Aster's astral form, ultimately destroying it and killing him.
 * Dimensional Warping: Mystique was notably able to access the Mirror Dimension and transport himself and the Zealots there without the Sling Ring. Mystique was also capable of conjuring a construct of the Mirror Dimension in the form of crystalline fractals that acted as a shield, absorbing an energy beam from the Power Stone, and was also able to send the fractals at Cricket.
