Since the release of Iron Man in 2008, Marvel's movies have been building to a cosmic conflict between Earth's Mightiest Heroes and the death-worshiping overlord Thanos. At the center of the oncoming conflict are the six Infinity Stones, each with different powers, that have manifested themselves in the various films, and which, when gathered, will form the Infinity Gauntlet, and box-office gold. Our panel will identify and discuss the infinity stones, their names, powers, and appearances in Marvel comics and Marvel's films, and their ongoing significance in determining the fate of Marvel's cinematic universe.
