While there was no line-up of all the Avengers as there was in 2011, director Joss Whedon made waves as he took the stage and announced the official title, and with it, the villain of the upcoming film. Ultron is a new name to many mainstream Marvel fans so the recent ten issue run also titled "Age of Ultron" is more than likely serve as an introduction to the baddie. If that run of comics is any indicator, Iron Man (Robert Downey Jr.) and co. will have much more to worry about than a partially destroyed New York City, especially with Whedon's penchant for killing off characters.
Avengers: Age of Ultron is scheduled to hit theatres in May 1, 2015.
