Batman would win because in Batman Arkham Origins, Batman defeated Deathstroke.
Heatherblaze's Opinion: I would say, Ezio. Because Ezio, has a gun, which, you can aim, fire, and hit. Altair falls over, dead. Ezio is more advanced from more bloodlines of assassins, so there is another advantage. Well, I just proved my point. It can be assumed that Ezio would be able to beat Altair. Altair was raised to be an Assassin from birth, but Ezio has better equipment like the hidden gun and uses a fresher, faster fighting style. Ezio would most likely win.
Batman would find a way to win.
Batman! :)
