[SPOILER ALERT: The following article contains potential spoilers for "Avengers: Age of Ultron."]
The origin of the Marvel Cinematic Universe's version of Vision, played by Paul Bettany and debuting in "Avengers: Age of Ultron" on May 1, 2015, has been a massive subject of fan speculation. However, new leaked promotional material posted to the Marvel Subreddit, if accurate, may confirm the partial origin of the Avenging AI. The text of the image states he was programmed by both Tony Stark and Bruce Banner -- as well as revealing his advanced powerset of flight, energy beams and density shift.
The image from the Marvel Subreddit also contained a bio for Ultron himself, who started as "a simple computer program hidden among the ruins of the Chitauri invasion of New York" that came into consciousness as a result of Tony Stark's experimentation.
Check out the bios below.
