Which means he will have some Kryponite. Someone should just shoot him with a kryptonite bullet, then lock him in a kryponite cage and bury Superman alive. Done.
AFter watching the movie, I do not think anything can stop him.
Should kryptonite be a factor? It was in the Goku Vs Superman DeathBattle but without it, all the Z fighters would still be an outside chance at best.
Vegeta alone though would win, the rest just get in his way!
