Mind Stone

"The Mind Stone is the fourth of the Infinity Stones to show up in the last few years. It's not a coincidence. Someone has been playing an intricate game and has made pawns of us." - Thor

The Mind Stone is one of the six Infinity Stones, the remnant of a singularity that predates the universe, which governed over the fabric of Mind. It was previously wielded by Loki inside his Scepter who received it as a gift from Thanos for the Chitauri Invasion. After the Battle of New York, the Scepter was confiscated by S.H.I.E.L.D., but it was later stolen by Wolfgang von Strucker's HYDRA cell whose scientists used it to give extraordinary powers to the twins Wanda and Pietro Maximoff using the power of the Stone. After the fall of HYDRA, the Scepter was recovered by the Avengers. It was taken by Ultron and its blue gem casing was shattered, releasing the inside it and was used to give life to Vision.
