Origin story
In the comics, young Gorr questioned his faith in the Gods when both of his parents died. Years later, he loses all faith following the death of his partner and their kids.
Power
Once, Gorr witnessed two Gods in a desert—one dead and the other injured. It's here that the dead God's weapon binds itself to Gorr giving him the power to stab the surviving God.
Necrosword
The weapon that binds itself to Gorr is the Necrosword. All symbiotes of Marvel Comics (like Venom) descend from this weapon. It allows for immortality and other superhuman abilities.
