Batman is one of the toughest non-powered heroes within the DC Universe as well as one of the smartest. There is no debate he is the greatest detective but there is some debate as to whether or not he has the ability to defeat the likes of Superman and other high powered heroes. Batman may not be able to defeat them, but he does have a contingency plan in case any heroes decide to go rogue. A prime example of this is within the pages of JLA: Tower of Babel. Within this story arc, we find Batman's has been keeping records concerning the strengths and weaknesses of his allies in the JLA, including plans to neutralise his allies in a fight. Another case of Batman's intelligence is he keeps a kryptonite ring in his utility belt in case he has to face Kryptonians or even the man of steel himself.
But can he defeat them with these contingencies in place? And what if Batman somehow makes it into the Marvel Universe? More than likely, Batman would get a feel for his surroundings and learn to adapt as he always does. The following fights will be left to the fans as to who is the better fighter. Assume Batman has been in the Marvel Universe for a month and has been in hiding, while gathering data on his coming opponents. If he were to face some of these characters, would he actually win, or would he fall? It's time for you to decide...is Batman tough enough?

"Sometimes, I admit, I think of Bruce as a man in a costume. Then, with some gadget from his utility belt, he reminds me that he has an extraordinarily inventive mind. And how lucky I am to be able to call on him." --Superman

This round seemed a little more favored to the dark knight. Personally, there are some of these heroes that should've taken Batman, but the voters have spoken.
