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?

Batman
"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

Mystique tries to use the power of seduction, but very few women have been able to succeed in that department. Raven then tries to shape-shift into Batman to imitate and throw the dark knight off but he is unphased. After a pointless attempt, Mystique goes down guns blazing but nevertheless, goes down...

Despite being a seasoned veteran, Nick Fury almost has no chance from the start. The battle ensues and within a matter of minutes, is laid out by the dark knight. Batman respects the war veteran but also wonders why this man is the head of S.H.E.I.L.D.

Paladin comes to the fight guns blazing but after nothing but misses, Batman gets close and lays him out with one combo...end of fight.

Both fighters are evenly matched and respect each other's fighting style but Psylocke is too quick for the dark knight and when she gets close enough, lands a hit with her pyschic knife. The blow leaves Batman on the ground, drooling and in a temporary state of vegetation.

If there's one thing Batman hates the most is a psychopath vigilante with guns. The dark knight takes this one a little personally and beats Punisher to a pulp. Castle doesn't stand a chance, but laughs as he's getting his face kicked in and teeth knocked out.

The southern belle doesn't have to do much in this fight. Batman tries to get the drop on Rogue but isn't quick enough. As soon as he attempts to land a blow, Rogue gets a hold of him and plants a kiss on the dark knight. He loses all his strength and is out cold.

Batman attempts to land a punch on Kitty but she continuously phases, goes solid and lands punch after punch on the dark knight. While she phases in and out, she is continuously shorting out Batman's gadgets so he can't use them. She eventually does enough damage to where she lands a final blow on Bruce.
