The Avengers: Age of Ultron

So, I know that everyone thought that Thanos would be the villain in the second Avengers movie, but apparently it's Ultron. This android was created by Hank Pym (aka Ant Man) and Tony Stark (aka Iron Man). The android was meant to help the Avengers, or store information, or fight the bad guys, or something, but it turned evil for some reason and turned on the Avengers. They told everyone about the Avengers sequel at Comic Con.
