Batman Vs Spider-Man
It does depend on which version of the characters, but 98% of the time, Spiderman is a teenager who gets called on to help the avengers every other week while still maintaining his advanced classes and designing/improving web fluid and other stuff and he can punch buildings down. He can beat Batman easily!
Ok, but Spiderman is really good at sneak attacks because genius spider, so if he just pops up behind Batman and swings, he wins. I mean, if anything the only reason Spiderman might lose is because he wouldn't want to play dirty like that, but morals aside Spidey wins
Who would win in a fight between batman and spider man?
