Re: The Avengers 2! The Official News and Speculation Thread - Part 4
what if Ultron has been created by Pym but in the background of the phase II movies.. ultrons creation was probably a secret joint project between shield (run by redford)/world security council and AIM to protect the planet
maybe some of the details of Jarvis' AI was stolen when tony's mansion was destroyed, and passed on to Pym (who not knowing the source) used it along with his brain mapping interface to create the ultron
i think they reference something like that in the A:EMH cartoon as well...
ultron become sentient and gather information on humans and potential threats to its existence
