I don't care if Batman shoves kryptonite up his ass and glows green for a year, all it takes is for superman to land one punch, or laser his ass from orbit. I mean Superman has literally bathed in the Sun, and towed planets to other galaxies to save them. If the writers of this movie load Batman down with such a massive amount of plot armor that he wins, then so be it, but just comparing the movie personas of Batman and Superman, there is no amount of kyrptonite that Batman could get his hands on that would stop Superman. For God sake Superman threw a fucking island of kyrponite into space after being prison shanked and then the blade being snapped off in his ass.
And something else, why does every Tom, Dick, and Harry have kyrponite. if we are talking about finite resources here, that shit should be gone. I mean Krypton is anywhere between 30-50 Light Years away from Earth depending on what source you go on, I don't even think that kyrponite would have made it to Earth yet honestly. But int he end Batman fans can have a good wank over the thought of Batman whooping Superman's ass, enjoy it, because this si for sure a fantasy story, within a fantasy story!
