One of the six Infinity Stones created by the Cosmic Entities, the Mind Stone enables whoever uses it to access the minds of others to control them or unlock untapped abilities. The Mind Stone was installed in the Chitauri scepter that Thanos gives to Loki to aid in the Chitauri invasion of Earth. After the Battle of New York, the scepter was confiscated by S.H.I.E.L.D. but was later stolen by Wolfgang von Strucker's HYDRA cell who used it in their research for enhancing human subjects with superhuman abilities which left only the twins Wanda and Pietro Maximoff as the sole survivors. After the Avengers recovered the scepter, Tony Stark's research on the object resulted in the creation of Ultron who later stole the scepter in an attempt to create an organic Vibranium body to further his own evolution and inadvertently led to the birth of Vision, who lost it to Thanos, who used it to create the Infinity Gauntlet.
