The heroes have gathered five of the Infinity Stones, but the villains track them down and steal the Stones. Thanos brutally beats the villains, kills most of them, and takes the Infinity Stones to put in the Infinity Gauntlet, becoming the most powerful being in the entire universe. What Kang the Conqueror predicted is coming to fruition. This is the heroes' greatest challenge in their entire lives. They must assemble, combine their powers, and fight as one to stop Thanos & hit him with everything they've got with help from some surprisingly new allies in this final showdown the universe has never seen. (Based on the "Infinity Gauntlet" comics, Avengers: Infinity War, Avengers: Endgame, & Marvel Ultimate Alliance 3: The Black Order)
