Convergence

"Once there were infinite Earths. Untold timelines. Innumerable Elseworlds. Then there came a Crisis... a Zero Hour... a Flashpoint. Worlds lived. Worlds died. Now, they all must fight for their future! The evil alien intelligence known as Brainiac has stolen 50 doomed cities from throughout time and space and brought them to a place beyond the Multiverse--a sentient planet of his own design, a world with the power of a god. As heroes and villains from dozens of worlds battle each other for their very existence, it's up to a ragtag band of warriors from a slain Earth to put an end to this threat that bends the Multiverse to its will. Reality itself hangs in the balance... This is it! The entire DC Universe from the dawn of time through the New 52 stars in Convergence--an unprecedented event that brings together your favorite characters from every era and series. Whether familiar or forgotten, none of them will ever be the same!" -- Page 4 of cover.
