Gorr is an alien whose race was slaughtered by Hela. He blames the Asgardians and, after years of searching, retrieved the Necrosword to wipe them out. Thor is having intergalactic adventures with the Guardians of the Galaxy when Gorr attacks and wounds him, then announces that he will kill the remaining Asgardians on Earth. Thor goes there to protect them with Rocket and Groot.
All leads to major battle between Thor and Jane against Gorr across time and space, while Valkyrie and Brand lead the Asgardians and S.W.O.R.D. in battle against the Shadow Berserkers to defend humanity.
