Re: The Design & Origin of ULTRON
I really don't want Ultron to be a corrupted Jarvis, other than what I speculated on, in that Tony was working on an AI system for the military, and they dumped the project, and he took the work that they did and made J.A.R.V.I.S. and based the A.I. on his father's butler. The military took what Tony was doing and corrupted it.
