Bane especially.

After years of crime fighting, Batman catches that crucial ass-whooping by a fucked up body builder on roids.

Yeah, and let's get Henry Rollins for that one. Box office hit.

No way. Get the Penguin, Cat Woman, Riddler even Mr. Freeze. Anybody but Bane.

And Azriel, there's no need. The first two Batman movies were already about the line between fighting crime and being a criminal. Introducing Azriel would just be redundant. IMO.

Personally I think Catwoman would be the best choice.
