Superman Batman (2010-) #24

The fate of the universe hangs in the balance unless the World's Finest Team—The Dark Damsel Detective and The Woman of Steel, that is—can stop it! There's nothing more incredible than the debut of Batwoman and Superwoman! Guest-starring Superlad! Well, maybe the Supergirls Squad!! Or the reveal of the villain behind it all and the death of a hero!!!!
