This epic adventure spans the Marvel universe from present-day Earth to the cosmic realm of Asgard. At the center of the story is The Mighty Thor, a powerful but arrogant warrior whose reckless actions reignite an ancient war. As a result, Thor's father Odin banishes his son to Earth where he is forced to live among humans. From Earth, Thor must make preparations to stop his evil brother Loki from dethroning Odin, seizing power and imposing his villainous rule on all of Asgard. When the darkest forces are sent to invade Earth, Thor learns what it takes to be a true hero.
Thor fights to restore order across the cosmos...but an ancient race led by the vengeful Malekith returns to plunge the universe back into darkness. To defeat an enemy that even Odin and Asgard cannot withstand, Thor sets out on his most dangerous and personal journey yet, forced into an alliance with the treacherous Loki to save not only his people and those he loves...but our universe itself.
The Mighty Thor is imprisoned on the other side of the universe...without his mighty hammer. He's in a race against time to get back to Asgard to stop Ragnarok, the cataclysmic destruction of his home world and the end of Asgardian civilization at the hands of an all-powerful new threat, the ruthless Hela. But first he must survive a deadly gladiatorial contest that pits him against his former ally and fellow Avenger - the Incredible Hulk.
The mercurial villain Loki resumes his role as the God of Mischief.
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. Together, they embark upon a harrowing cosmic adventure to uncover the mystery of the God Butcher's vengeance and stop him before it's too late.
