O.E.: Take this from a DC fan; Spider-man would wreck Batman. Batman's biggest asset would be prep time, but if you give Batman prep time, you give Spider-man prep time, and seeing as Otto Octavius is still in command of Spider-man's body, his prep advantage would find a way to cancel out any prep Batman could create. Spider-man's "Spidey Sense" would allow him to dodge and counter ANYTHING Batman can do; hell, it allows him to dodge automatic gunfire at point-blank range. His strength, speed, and durability are greater than anyone Batman has faced without prep time (Bane on venom is still the strongest Batman foe physically and he's a 7 tonner at best, Spider-man is a 25 tonner.) I'm sorry Batman fans, but Spider-man has him outclassed, and before anyone tries to counter with "Batman has beaten Superman, of course he can beat Spider-man", Batman has never won against Superman in DC canon, so any feat involving him "beating" Superman is automatically invalid.
