When reality begins to fracture across timelines, Earth’s mightiest heroes face a threat beyond imagination. Robert Downey Jr. returns in a shocking new role—no longer the man they trusted, but a mind twisted by cosmic power. Opposite him, Chris Hemsworth brings thunder as Thor, leading a desperate resistance against an unstoppable force.

With the return of familiar faces and new warriors rising, alliances shatter and loyalties are tested. From collapsing cities to interdimensional warzones, every battle pushes the Avengers closer to extinction. A mysterious figure emerges from the multiverse, holding the key to survival… or total annihilation.

As hope fades, one final mission could rewrite destiny—but at a cost no hero is ready to pay.
