The Mighty Thor

Film 41 of the official Underworld Productions Marvel Cinematic Universe

Lightning splits the cosmos as Thor is torn from Earth by Heimdall’s final warning—Ragnarok approaches. In Asgard, King Baldur the Brave gathers Thor, Lady Sif, Beta Ray Bill, the Warriors Three, and Valkyrie. Their only hope: find Eternity across the Nine Realms. Their quest becomes a psychedelic warpath through shattered worlds, demon suns, and living storms as Ulik and Kurse clash with them in explosive set pieces that bend reality itself. A shadow follows—Gorr the God Butcher, wielding the All-Black blade. He ambushes Olympus in a brutal massacre, killing Zeus while Hercules is forced to watch. Gorr declares Thor his final trophy. Unseen, Loki—escaped after Odin’s murder—tracks everything, recording their path to Eternity. He plans to claim its power and rule all realms. Thor’s team reaches the cosmic gate, but Gorr intercepts. In a battle, Bill and Sif hold the line while Thor duels Gorr across collapsing space. Sif evacuates Asgard as Surtur rises. Thor makes the choice: abandon Asgard to save Olympus from extinction. He kills Gorr—but arrives too late. Ragnarok begins. At Eternity’s edge, Loki witnesses Thor’s last stand and, shaken, chooses sacrifice over power. He begs Eternity to restore Asgard. Green light floods creation. Thor sees a serpent-shaped aurora and understands. Eternity grants Loki passage. He goes to Doom, rejects the Cabal—only for Doom to murder him and steal his power. Thor returns home. Baldur asks him to stay. Thor smiles. He’s going back to Jane.
