Ok so he might not be a ninja, but he is an expert in all forms of martial arts and he has a high knowledge of pressure points.

Wolverine is a ninja too.... even better than Batman because he is way more experienced.

As much as I hate Superman, because he is so over powered, I would have to say he would win, but he would only win if he were to go against his own morals and actually kill someone.

I like both superheros, but i would have to choose Wolverine as the ultimate superhero. Wolverine has one power and it is his mutant healing factor. It would take so much to kill him compared to both Captain America and Batman. Wolverine feels all of the pain that is inflicted upon him, whether it be from himself or anyone else, and he still continues to put himself in places that will no doubt cause him physical harm. I mean every time he uses his claws he has to eject them through his skin, how many superheros hurt themselves before a fight. I know some of you might argue that Wolverine's adamantium and claws are powers, but they are not. His claws are part of his bone structure and the adamantium was put into him. As for characteristics, Captain America and Batman are both really great people that have really great character and thats where they probably beat Wolverine because he can be a pretty mean guy sometimes, but i mean if you were over 120 years old you wouldn't be that nice of a guy either. Look at some of the elderly people, they can be quite grumpy. Also, a lot of people choose Batman as the best because he has no powers. Well Iron Man has no powers and Captain America has no powers either, he is just altered by a serum.
