The Mind Stone is arguably one of the most important Infinity Stones in the Marvel Cinematic Universe. Wanda Maximoff, Vision and Pietro Maximoff all received powers from the Mind Stone. Wanda Maximoff and Vision are two very powerful characters within the MCU, without Wanda the final battle in Endgame would have turned out very differently. Not only did the Mind Stone give the MCU powerful heroes, it also gave the universe two interesting villains; Loki and Ultron. The mind stone was imbued in Loki’s scepter and without that stone the first Avengers movie would be far less interesting. In terms of Ultron, the Mind Stone gave him life and yet also made the Avengers better understand themselves as a team.

The Mind Stone was the last Infinity Stone to be taken by Thanos in Avengers: Infinity War whereas the Space Stone was one of the first. The Mind Stone held on as long as it could, and may have never been taken if the other stones weren’t given away or stolen first. Vision and Ultron were able to take down Thanos with just the Mind Stone when Thanos went against them with the power of the other five stones in the MCU show ‘What If?’.
