Okay, this one should really remain in the maybe pile until official proof to the contrary arrives, but it seems pretty unlikely that Superman will make it through two movies in a row without facing the threat of his Achilles heel. Man Of Steel was actually somewhat refreshing in as far as Kal-El didnt have to deal with kryptonite for a change. Still, with little prospect of any other Kryptonians entering the fray its a good bet that he wont be so lucky this time. After all, many casual observers have already pointed out that Batman V Superman is hardly a fair fight, regardless of whatever shiny new gadgets Bats has hidden in his utility belt. Were someone to provide him with a little kryptonite, on the other hand One of the problems with Superman on the big screen is just how difficult it is to create a suitable threat against a character whos practically indestructible, which is why Lex Luthor tends to have a little chunk of Kal-Els homeland hidden away somewhere. Its nothing more than speculation at this point, but that could change very quickly when the first trailer drops.
