Injustice 2, Vol. 4

Batman looks for allies in an unexpected place—the Phantom Zone—and what he finds may change the course of his war with Ra’s al Ghul! The Dark Knight leads his team—including Harley Quinn, Catwoman, Plastic Man, Green Arrow and Black Canary—to Superman’s abandoned Fortress of Solitude in hopes of freeing the Teen Titans from their years-long exile in the Phantom Zone. But the Fortress isn’t abandoned, and more than just the Titans are about to escape the Phantom Zone! It’s a rescue with unexpected casualties, and success will require the return of one hero near death and another one long vanished! Collects INJUSTICE 2 #18-24.
