Vision
Tony Stark and Bruce Banner work together to upload the artificial intelligence J.A.R.V.I.S. into a robotic body. Thor gives it the Mind Stone, and Vision is born. With red skin and the Mind Stone on his forehead, there is nothing that this android cannot do!
Paul Bettany, who plays Vision in the MCU, was originally hired as the voice of J.A.R.V.I.S. However, director Joss Whedon decided to cast him as Vision in Avengers: Age of Ultron. Bettany had to wear a full-body prosthetic suit and contact lenses for this role.
