I filmen
Vision’s body is created by Ultron as a final stage of his evolution; a final body for him. The body is created as a combination of genetic material and Vibranium. However, before Ultron can fully upload his mind into the body, it is stolen by the Avengers, and Stark and Banner load it with a modified version of JARVIS as a consciousness.
