Let's assume that none of them get the plot armor that normally shields them in their own movies. (Sorry Aragorn, Alice, Xena, and Achilles.) Honestly, with that group, I see Rambo winning it. He's mean, tough, trained, and crazy. Nope, not Batman. Look at which Batman it is. Bale-Batman is, quite frankly, kind of an idiot. I don't see him able to take Rambo in a Hunger Games situation, unless he got a lot of sponsorship.
