So, by the end of Batman Returns
End of Batman Forever
End of Batman & Robin
End of The Dark Knight Rises,
All four movie Batmen - bar Affleck, because it'd be too soon, or West, as it seems unfair to him - fight one another.
With ALL gadgets, full physical peak, and best armour/costume they got, filmwise, or final.
Who lives/wins/dies?
And, as a BONUS MATCH, the winner/survivor fights Bane, of Batman & Robin - best physical from the series I can think of - and then Ras' Al Ghul, of Batman Begins.
Who wins that?
