Vision is an android who possessed a synthetic vibranium body created by Ultron and Helen Cho, along with the powerful gem known as the Mind Stone.
Real Name: Vision
Date of Birth: May 2015
Portrayed by: Paul Bettany
1. Avengers: Age of Ultron
Originally conceived as the perfect form for Ultron, the body was stolen by the Avengers, after which it was repurposed by Tony Stark and Bruce Banner, who uploaded the remnants of Stark's personal A.I. J.A.R.V.I.S. into it.
Upon his birth, Vision declared he was a mixture of Ultron and J.A.R.V.I.S., one that would fight to protect humanity at all costs. Vision then joined the Avengers in the Battle of Sokovia, using his powers to prevent Ultron from transferring his consciousness into the internet and allowing the Avengers to successfully put an end to him.
2. Captain America: Civil War
Following the aftermath of the Ultron Offensive, Vision became an official member of the Avengers under the leadership of Captain America. The new Avengers team did not last long as Vision sided with Tony Stark in supporting the Sokovia Accords, which put him into conflict with Captain America and his faction.
As a result, Vision became involved in the Avengers Civil War, where his own newfound feelings for Scarlet Witch caused him to accidentally injure War Machine during the battle, or if the Mind Stone was acting on its own.
3. Avengers: Infinity War
Vision and War Machine, along with Iron Man became the remaining members of the Avengers, staying at the New Avengers Facility while also double living with Wanda Maximoff in Europe.
While living a quiet life, Vision was ambushed by the Black Order, in pursuit of the Mind Stone. As a result, Vision's endangered life was brought to Wakanda, where Vision was protected from the oncoming assault of Outriders.
In an attempt to stop Thanos from gaining the Mind Stone, Maximoff reluctantly destroyed the Stone, and Vision along with it. However, Thanos, using the Time Stone, undid the Mind Stone's destruction and then ripped it out from Vision's head, effectively shutting him down.
