Batman would win because in Batman Arkham Origins, Batman defeated Deathstroke.
Even Batman has trouble when he fights Deathstroke. It's impossible for Kim Possible to defeat Deathstroke.
Captain America, obviously. He would beat Deathstroke up.

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.
