Supergirl (2005-) #41
The dramatic conclusion of 'Who is Superwoman?' Superwoman stands revealed, leading to a knock-down drag-out fight the likes of which Metropolis will be talking about for years to come! Supergirl will wish she'd never found out who was under the hood as Superwoman and Reactron join forces to make sure the Girl of Steel can never use that information again! How can Supergirl possibly survive?!?
