Batman would win because in Batman Arkham Origins, Batman defeated Deathstroke.

Batman of course
Batman, because he isn't lame.
Mario dies when a turtle touches him. Batman can fight the Joker, and still walk away fine. Batman would win.
There is no hard data on who would win a fight between Batman and Cat woman, but she is quick and a cat and fights dirty. but men are stronger so it could be a fair fight.
Batman.
Samus would win a fight in beating Batman because she has all those powers in her Power Suit.
Batman without a doubt. Batman knows how to do everything.
