Gorr was an inhabitant born on an unnamed planet where resources were extremely scarce. Many of the inhabitants were devotees of the god Rapu and believed they would receive an "eternal reward" for their devotion to him. However, much time passed and many of the inhabitants eventually died of starvation, leaving Gorr and his daughter, Love, as the last living beings at that time.
Although Gorr prayed to Rapu for help, his daughter ultimately died of starvation, leaving him devastated. After burying his daughter, Gorr resolved to wait for his own death only to hear whispers, following them to a lush oasis. Grateful for food and water, Gorr was interrupted by Rapu standing near the corpse of a dark god wielding a black sword. Recognizing him, Gorr immediately bowed to his god before introducing himself as the last of his disciples, believing that the oasis was a reward for his unwavering faith.
Rapu mocked Gorr and made it clear that all this feast was to celebrate the death of the Necrosword's wielder, who had attacked him and threatened to destroy his empire. When Gorr pointed out that there was no empire left, Rapu responded that there would always be more followers to replace him. Gorr, enraged, repudiated his god and Rapu grabbed him by the throat, proclaiming that Gorr now had a purpose: to die by his hand. Resonating with Gorr's hatred, the Necrosword moved through the shadows and levitated into Gorr's hand, whispering to him that he must find Eternity using a Bifrost Bridge. Gorr stabbed Rapu in the throat, the god warning Gorr that the Necrosword had chosen him and that he was now cursed. Uncaring, Gorr swore that all the gods would die by his hand, beheading Rapu and starting a slaughter to find Eternity.
Claiming the Shadow Realm - a dark dimension tied to the Necrosword - as his base of operations, Gorr mastered the use of its dark powers, learning how to teleport using shadows and summon monsters made of living darkness. Learning of Thor Odinson, Gorr attacked New Asgard with a horde of Shadow Monsters and abducted several children, intending to blackmail Thor into surrendering Stormbreaker so that he could use its Bifrost to reach Eternity.
