That night, Gorr uses the Necrosword to swarm New Asgard with shadow monsters. As Thor has unknowingly enchanted it to protect Foster while they were together, Mjølnir becomes drawn to her presence, fusing itself back together and imbuing her with the powers of the Mighty Thor. Efforts to research for a cure prove futile and she beings to lose hope, but Foster becomes inspired to travel to New Asgard in hopes that their magic can help eliminate the cancer. Jane Foster undergoes treatment for stage IV cancer. They find a defeated Sif with her arm severed, who warns them that Gorr will attack New Asgard next. Thor and Korg respond to Sif's call, parting ways with the Guardians who leave to respond to the others. An influx of distress calls regarding Gorr emerge, one of them being from Sif, who had hunted him down.

However, Thor remains discontent with where he is in life, and intends to retire. Thor continues his adventures with the Guardians of the Galaxy, responding to distress calls across the universe while working to get back in shape. Feeling betrayed, Gorr claims the Necrosword and beheads him, and vows for the elimination of all gods. Rapu makes fun of Gorr for his helplessness and refuses to provide any assistance. Just as he begins to hear a voice calling out to him in the distance, Gorr discovers an oasis where he finds Rapu, who had killed the latest wielder of an ancient weapon known as All-Black the Necrosword. He prays to his god Rapu for help, but his daughter soon dies of starvation. Gorr, the last of his people, spends his days striving to survive on a barren desert with his daughter. 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. 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, Mjølnir, as the Mighty Thor. But his retirement is interrupted by a galactic killer known as Gorr the God Butcher, who seeks the extinction of the gods. The film finds Thor on a journey unlike anything he’s ever faced - a quest for inner peace.
