Re: The Design & Origin of ULTRON
Here's what I think may happen re: Ultron in A2:
Robert Redford's SHIELD character decided to start making machines that can replace Avengers in the future, called Project Ultron. He tapped the brillant scientist Dr. Pym to develop the machines, and he created the program and personality of Ultron. However, he failed to create the right robotic body for Ultron so Redford's character turned to Stark for help, and lied to him about the whole project. Stark is no longer Iron Man so he lent his help, and created the body (but not face) of Ultron. Pym added the face later. Ultron went rogue and Stark felt guilty, so he designed a new armor and become Iron Man once again, to help Avengers to take down Ultron. Pym's story will continue in Ant Man.
