Powers & Abilities

 * Infinity Gauntlet - By using all the Stones, he can destroy a whole city using it and using the infinity stones' abilities, it was shown by Ultron.
 * Space Stone - The Tesseract is named for its cube-like appearance and is capable of controlling the space, providing the user instant access to any location throughout the universe if used correctly. The unique element that composes the Tesseract has also been used to create advanced weaponry by races like the Humans.
 * Mind Stone - The Scepter was a weapon that utilized the yellow Mind Stone housed inside a blue computer module, which also masked the stone's presence. Stark originally saw the Stone as a power source, whereas once J.A.R.V.I.S. had the opportunity to study the stone he stated it was more akin to a very powerful computer. The stone within had already been in the possession of Thanos when he gave it to Loki to aide him in his invasion of Earth, but it is now owned by Vision.
 * Reality Stone - The Aether appears as a dark, red, viscous liquid. It acts like a symbiotic force, capable of being absorbed into the body of a living host, giving the user the ability to warp reality at will, granting that person immense strength, power, and seemingly unlimited capabilities.
 * Power Stone - The Orb is the protective housing of the purple Power Stone. The stone is an incredible power source, it increase the user's physical abilities and allows it to manipulate energy, which, when used at full potential, has enough power to obliterate an entire planet.
