Against his father Odin's will, The Mighty Thor - a powerful but arrogant warrior god - recklessly reignites an ancient war. Thor is cast down to Earth and forced to live among humans as punishment. Once here, Thor learns what it takes to be a true hero when the most dangerous villain of his world sends the darkest forces of Asgard to invade Earth.

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.

Hungry for adventure, Thor secretly embarks on the journey of a lifetime, joined by his loyal brother Loki, whose budding sorcery equips him with just enough magic to conjure up trouble, along with the Warriors Three - a band of boastful travelers reluctant to set sail on any adventure that might actually be dangerous. But what starts out as a harmless treasure hunt quickly turns deadly, and Thor must now prove himself worthy of the destiny he covets by saving Asgard itself.

For ages, Odin has protected his kingdom of Asgard. But every winter, the All-Father must rest and regain his strength for one week. During this time, all of Asgard's foes (including trolls, giants, dark elves, and demons) try to claim the realm for their own, but they are always stopped by Odin's son, the mighty Thor, albeit with the loss of many brave Asgardian warriors. Loki, god of mischief, has kidnapped Dr. Bruce Banner and brought him to Asgard with the help of Amora, once Thor's lover, now the supervillain known as the Enchantress. Loki makes Banner angry and he changes into the Hulk. The Enchantress then casts a spell over the Hulk which separates Banner from his monstrous alter-ego and grants Loki control over the Hulk's body.

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. Faced with an enemy that even Odin and Asgard cannot withstand, Thor must embark on his most perilous and personal journey yet, one that will reunite him with Jane Foster and force him to sacrifice everything to save us all.

After his retirement is interrupted by Gorr the God Butcher, a galactic killer who seeks the extinction of the gods, Thor Odinson enlists the help of King Valkyrie, Korg, and ex-girlfriend Jane Foster, who now wields 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.
