Plot
APOKOLIPS IS ON THE HORIZON...AND NO ONE IS SAFE! In the wake of the We Are Yesterday crossover epic, a mysterious Quantum Quorum has emerged...stalked by a lethal enemy that takes no prisoners. The League deputizes a rag tag group of time displaced heroes like Batman Beyond, Gold Beetle, and Helena Wayne to fill the void left behind by the Time Masters and save the quorum from the mysterious threat that's picking off time-travelers one by one. These Legends of Tomorrow are the only ones standing in the way of this cascading chronal Armageddon with the past, present, and future teetering on the brink in this oversized special leading to the next big DC All In event!
