Thor almost defeats the Hulk, before the Grandmaster fixes the fight to ensure the Hulk's victory. Thor is forced to compete in the Grandmaster's Contest of Champions, facing his old friend the Hulk. Thor recognizes 142 as one of the Valkyrie, a legendary force of female fighters who were killed defending Asgard from Hela long ago. He is captured by a bounty hunter named Scrapper 142, and taken to serve as a gladiator for the planet's ruler, the Grandmaster, whom Loki has already become ingratiated with. Thor crash-lands on the planet Sakaar, a garbage planet surrounded by wormholes. She plans to use the Bifröst to expand Asgard's empire, but Heimdall steals the sword that controls the Bridge, and hides away with the rest of Asgard's citizens. Hela arrives in Asgard, destroys its army along with the Warriors Three, resurrects the ancient dead and the Fenris Wolf who once fought with her, and appoints the downtrodden Asgardian Skurge as her executioner. She destroys Thor's hammer Mjolnir, and when Thor and Loki attempt to flee through the Bifröst Bridge, she pursues them and forces them out into space to die. Hela had been the leader of Asgard's armies, and had conquered the Nine Realms with Odin, but had been imprisoned and written out of history after her ambitions became too great.

Odin explains that he is dying, and that his passing will allow his firstborn daughter Hela to escape from a prison she was sealed in long ago. Thor forces Loki to help him find their father, and with directions from Stephen Strange on Earth they locate Odin in Norway. Thor returns to Asgard to find his adopted brother Loki posing as Odin.

Thor defeats Surtur and claims his crown, believing he has prevented Ragnarök. Surtur reveals that Thor's father Odin is no longer on Asgard, and that the realm will soon be destroyed in the prophesied Ragnarök, once Surtur unites his crown with the Eternal Flame that burns beneath the city. Two years after the Battle of Sokovia, Thor has been unsuccessfully searching for the Infinity Stones, and is now imprisoned by the fire demon Surtur.
