The Infinity Stones are going to come together in the Marvel Cinematic Universe for the first time during the Avengers: Infinity War movies. Thanos will likely be the one who wields all six - being one of the few beings in existence powerful enough to handle them - and he will be able to perform all manner of tricks with them. However, should anybody else get their hands on them - someone without the experience of controlling such power - anything could happen. In the future, a character without the experience required to handle the power of the Infinity Gauntlet could get a hold of it and make a real mess of things - perhaps accidentally turning the bulk of the world's population in to zombies! This would be a cool nod to the Infinity Gauntlet comic book arc, when Thanos transformed Nebula into a horrific, rotting, living corpse, while also delivering a unique cinematic twist on the Marvel Zombies concept.
