Re: The Design & Origin of ULTRON
Random thought: do we know that the Clean Slate protocol really destroyed all the armors... "I'm sorry, Sir, I'm afraid I can't do that."
Alternately, I once suggested that if AIM is still around, well, they had access to the War Machine/Iron Patriot armor.
But more importantly, the question we should be asking is what kinds of personal links would Ultron have to Avengers other than Tony? If it involved Asgardian destroyer tech, that would get Thor involved. With Winter Soldier's cybernetic arm, maybe there could be some kind of link to Cap there? Though WS is said to have a big set up for A:AoU at the end, so I guess we'll have to see what that is. Widow and Hawkeye are SHIELD agents, so not hard to get them involved... But what about Banner?
