I just had a random theory about Avengers: Age of Ultron.
It’s been posited elsewhere that Ultron evolves from J.A.R.V.I.S. I submit that Ultron is actually Dummy, Tony Stark’s first robot that he created as a kid and used as an assistant/fire extinguisher in his lab. Stark was never very kind to Dummy, so it probably has a lot of pent up hostility. Plus, Dummy is the only piece of hardware that Stark salvages at the end of Iron Man 3. As far as we know, J.A.R.V.I.S. is long gone.
You heard it hear first, people: Ultron is Dummy. Anyone care to blast holes in this theory?
