The Infinity Stones are six immensely powerful objects tied to different aspects of the universe, created by the Cosmic Entities. Each of the stones possess unique capabilities that have been enhanced and altered by various alien civilizations for millennia.
The Power Stone Can Wipe Out Planets
Just as its name suggests the Power Stone is one of the most powerful of the whole set. As first seen in Guardians of the Galaxy, the Power Stone (that was contained within the orb) has incredible capabilities that can destroy entire planets if harnessed the right way.
The Space Stone Can Open Gateways
The Space Stone has the ability to manipulate space by teleporting people and things, increasing the speed of the user, allowing someone to appear in two places at once, and just generally messing with the laws of physics.
The Mind Stone Can Control People
The stone strengthens and enhances mental and psychic powers, including telepathy and telekinesis, and can access other people’s thoughts. When used in conjunction with the Power Stone to enhance its own properties, the Mind Stone can connect the user to all other minds in the universe simultaneously.
The Reality Stone Can Bend Physics
Also as the name suggests, the Reality Stone has the ability to wrap reality.
It can create endless alternate realities, it can grant any wish you make, and can even break the laws of science and logic. It can resurrect the dead ; it pretty much hast the ability to do anything that would normally be impossible. Because of this, it is considered one of the most powerful stones in the collection. When used with the Power Stone, the reality-bending can be pushed out to a universal scale.
The Time Stone Can Control Time Itself
As the Infinity Stone that represents and governs over the flow of time, the Time Stone is among the most powerful artifacts in all existence. Due to its power, it cannot be held and used by anyone not powerful enough to withstand it, thus forcing Agamotto to create the Eye of Agamotto as a container to allow other sufficiently advanced sorcerers to wield it.
The Soul Stone Harvests Souls
The Soul Stone ranks as one of the most powerful artifacts in all creation. However, as it represents and has absolute control over the fabric of the Soul, resulting in its more esoteric and enigmatic powers compared to the other Stones, said to have power over the cycle of life and death, the Soul Stone is often considered the most dangerous by some, and holds a special standing even among the other Stones.
