Gamora

As many comic book fans suspected, Guardians of the Galaxy’s MacGuffin is another of the Infinity Stones. Now in the possession of the Nova Corps, how exactly Thanos is going to get his hands on all of these remains to be seen. The Tesseract (from Captain America: The First Avenger and Avengers Assemble) is in Asgard, Loki’s staff – given to him by Thanos – is in the hands of Hydra, and the Aether is still seemingly part of The Collector’s collection. Thanos will need six of them before he’s able to wield the Infinity Gauntlet, so where the other two are remains to be seen. Either way, now that we’ve been introduced to Josh Brolin’s take on the villain, expect his hunt for the Infinity Stone to take a step to the next level as we build towards The Avengers 3 and beyond…
