Only the most eagle-eyed fan would have seen the Infinity Gauntlet sitting in Odin’s Trophy Room in Thor. For those unaware, the Infinity Gauntlet is a giant metal glove with five all-powerful Infinity Gems affixed to each knuckle, and one last one attached at the top of the hand. It was forged by the Mad Titan, Thanos, and was the subject of one of Marvel’s most popular miniseries, The Infinity Gauntlet. In Thor, when the Ice Giants attempt to steal the The Cask of Ancient Winters, the Gauntlet can be seen ever-so-briefly in the background.
