So with MCU Thor getting his new weapon stormbreaker, I think it's only fair DCEU Superman should be given a weapon. Of course his weapon of choice the Superman sword hasn't been introduced into the movies so he's going to have to pick another, so he borrows WW's sword for the encounter.
Both are blood lusted, to the death to win, Superman has witnessed Thor killing Lois Lane and Thor has witnessed Superman killing Loki. They start on an open field 100 meters apart.
So is Superman too fast and can just speed blitz Thor and slice his head clean off or will Thor manage to counter the blow and overcome Superman and kill him with his new toy?
