Death Battle did this on YouTube. The answer is clearly Spiderman
He'd keep Batman distracted with his off the chart humor and stick webs to his hands and face.
i voted spider man.
Simply having the money that Batman has, he would easily win against a face off against spiderman.
Batman is a billionaire.
Batman is more experienced in fighting then Spiderman. I know that for a fact 'cause my sister is obsessed with DC comics.
Quite simply, BECAUSE HE'S BATMAN!!!
