Thor: Ragnarok

Odin dies, Hela destroys Mjolnir, Asgard is destroyed and Thor becomes king. The mid-credits scene leads directly into Infinity War.

Thor is imprisoned on the other side of the universe and finds himself in a race against time to get back to Asgard to stop Ragnarok, the destruction of his home-world and the end of Asgardian civilization, at the hands of a powerful new threat, the ruthless Hela.
