Fan Casting Iron Man 3

After the confrontation with Doctor Doom, Tony became scared for the first time. Upgrading his suit, he dives into the past of Black Widow, to find that they look alike more then he thinks. He and Hank decide to work together on a secret project. Project Vision, so they have a robot who could fight for them. Always willing to and protecting the city. The prototype isn't going that well, so after they had thrown that away, the second one seems to work perfectly. Only what they don't know is that the first type has his own thoughts about the situation too.
