Fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day saviour, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
As for this ‘new threat’, whether it will be coming from the skies or from mankind (or maybe just Lex Luthor) is still anyones guess. Although there has been much rumour about Doomsday. But not sure that even director Zack Synder would lean on bringing out the heavy artillery this early on in the DCU.
