Speaking to CraveOnline about the mid-credit scene in Thor: The Dark World, Marvel Studios boss Kevin Feige confirmed that the Aether and the Tesseract from Captain America: The First Avenger are the first of the Infinity Gems.
In the comics, the Infinity Gems are sought by the Mad Titan Thanos for his Infinity Gauntlet, giving him near-limitless power. One of the key questions for fans, though, was just which stones are which, as neither the colours and abilities of the Tesseract and the Aether match their comic-book counterparts.
“I don’t know when we’ll actually divulge that necessarily, but it’s the Space stone,” said Feige of the Tesseract, which opened a rift in space in Avengers Assemble, while the Aether is the Power stone, which grants superhuman abilities.
This leaves Soul, Time, Mind and Reality.
“One down, five to go,” as the Collector said – and in the comics it’s the Collector that trades one of the gems to Thanos. Asked if the Infinity Gems would be a big part of Guardians Of The Galaxy or Marvel’s Phase 3 movies, Feige replied:
“Well the answer to the first question is both. It is both. And then, you know? Who knows? If they allow us to keep making movies, it will go a little bit further.”
