Finally, someone has the good sense of showing us how a fight between Superman and Batman would end up. T’was about time.
They showed us years ago how the fight would go in Frank Millers, the dark knight returns. Superman got his ass kicked.
Actuly superman would be defeated ina s ense in the comic books he gave batman kryptonite just incase he went evil and that it would kill him. He keeps it in his utlitie belt for that just in case thing.
It takes time for Kryptonite to work on Superman. He’d still be vastly stronger than any human for much longer than it’d take to snap his neck.
