Breaking down the possibilities presented by Marvel's classic android
Expanding the Avengers Roster
With the first installment of "The Avengers," moviegoers got to know the roster of Earth's Mightiest Heroes as the six individuals that assembled in the film (seven counting Nick Fury), but longtime fans know that the roster of the Avengers is actually one composed of dozens of heroes. "Age of Ultron" is already gearing up to expand its list of characters by a significant amount, and it seems inevitable that at least a few will become full-fledged Avengers.
While the most obvious first new recruit to the team is "Captain America: The Winter Soldier" co-star the Falcon (Anthony Mackie), there has yet to be an announcement guaranteeing the high-flying hero is joining the Avengers sequel. If Cap's new partner doesn't make the leap to the team, the Vision could be the first recruit, along with Scarlet Witch and possibly Quicksilver. That would take the team from six heroes to nine, opening the doors to the legendary and varied roster fans of the comics have grown to love.
