Mind Stone

Mind Infinity Stone
The Mind stone first appeared in The Avengers (2012), inside the sceptor, when loki arrived on Earth. Black widow used it to close the portal and then it got into the hands of the Strucker. He experimented with it on two twins named Wanda and Pietro Maximoff in Captain America - The Winter Soldier (2014), who became the Scarlett Witch and Quicksilver. Then the Avengers attacked Strucker and took it in Avengers - Age of Ultron (2015). Tony Stark and Dr. Bruce Banner used it to create Ultron's mind and then Ultron, with his vibranium body and robots, stole the sceptor. He, with hypnotysed Dr. Helen, was creating a more powerful body (Vision's body) when he broke the sceptor, took the Mind stone and put it in Vision's head. The Avengers created the vision and they defeated Ulton and destroyed Sokovia. Then Vision also agreed to sign the Sokovia Accords and fought team Cap in Captain America Civil War (2016), but falls in love with Wanda and both go to Scotland for spending time with each other. At last Thanos picked the Mind Stone from his head and put it inside the Infinity Gauntlet.
