Batman is all technology, some serious damage dealing stuff, but without a kryptonite weapon Superman ftw hands down
Let's face it. Superman would reck batman from hunderd miles away, not because of intelligence cause batman is clearly more intelligent, but bat just doesn't got the range/powers to comprehend with superman. Batman only won in the comics because superman held back, got help from greenarrow and most important because he is more popular.
It always comes down to kryptonite. Batman's metal armor/ironman look is ok and all, but we all know batman has never been able to bring superman down without green rocks. Lex is going to be prominent as well in this one, so we can expect luthorcorp to be where Batman learns of kryptonite (or he may just steal it from Lex)
If Batman can beat superman when he's like 50+(Comics) I'm pretty sure he can beat superman during his prime lol
Dont think anyone will win they will end the fight with a mutual agreement watch and batman will use his piece of kryptocrack to get a leverage over superkid
