The Infinity Gems (originally referred to as Soul Gems and later as Infinity Stones) are six fictional gems appearing in American comic books published by Marvel Comics, named after and embodying various aspects of existence. The gems can grant whoever wields them various powers in accordance to the aspect of existence they represent, and have the potential of turning the wielder into a god-like being when the main six (Mind, Power, Reality, Soul, Space, and Time) are held together. Thus, they are among the most powerful and sought-after items in the Marvel Universe; playing important roles in several storylines, in which they were wielded by characters such as Thanos and Adam Warlock. Some of these stories depict additional Infinity Gems or similar objects. Although the Infinity Gems altogether give their user omnipotence, the Gems only function in the universe they belong to and not in alternate realities.
The Gems have appeared in several media adaptations outside of comics, including the Marvel Cinematic Universe film franchise, where they are called Infinity Stones and have their colors altered. These changes were later adapted into the comics.
