There was an idea, Stark knows this, called the AVENGERS INITIATIVE.
The idea was to bring a group of remarkable people to see if they could become something more; to see if they could work together when we needed them to; to fight the battles that we never could - Nick Fury (Marvel's The Avengers).
Its an adrenaline rush to see our remarkable superheroes gearing up and fight the battles, even stop an alien invasion. But the techs are more advanced; the rush is infinite; the stakes are huge and the world is at peril.
Lets have a head count here with our favorite avengers in the new "Age Of Ultron".
