Wonder Woman! Swamp Thing! Zatanna! Man-Bat! Um...Detective Chimp! The JL Dark team may not be strong or deep enough to stop the omnipotent Upside-Down Man from taking over our entire plane of existence. UDM takes the JLD apart one by one, but Wonder Woman might have enough mojo to keep everyone alive. Turns out Diana had a power not even she knew about that bursts to the surface, but will it be enough to turn the Upside-Down Man on his head, or is it just a lot of mystical mumbo jumbo?
