Avengers: Infinity War
As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment - the fate of Earth and existence itself has never been more uncertain.
Thor: Ragnarok
The end of Asgard and its people, Ragnarok, begins at the prompting of Hela, the Asgardian goddess of death and the underworld. Thor loses his hammer Mjolnir, the powerful weapon forged in a dying star's core that he relies on in battle. He's then imprisoned on a planet named Sakaar where he's forced into slavery and gladiator-style combat. In the fighting arena, Thor learns that Bruce Banner's alter-ego the Hulk, his fellow Avenger and friend, is Sakaar's greatest gladiator. His only hope is to convince Banner and the Hulk to help him escape and save his homeworld.
