The God of Thunder finds himself on a journey unlike anything he’s ever faced—one of self-discovery. But his efforts are interrupted by a galactic killer known as Gorr the God Butcher, who seeks the extinction of the gods. To combat the threat, Thor enlists the help of King Valkyrie, Korg and ex-girlfriend Jane Foster, who—to Thor’s surprise—inexplicably wields his magical hammer, Mjolnir, as the Mighty Thor.
