How was batman able to beat bane the 2nd time wheb he didn't phase him in the 1st fight?
I would refer to their first fight where Bane says "Oh, you think the darkness is your friend? You merely adopted. I was born into it. Molded by it." Not that this makes logical sense, but Bruce spent time in the "darkness" like Bane, and came out tuff and junk. Plus he hit Bane in the mask. That helped.
