This crossover will consist of 5 episodes (AKA all Arrowverse shows) over 2 parts with Black Lightning characters set to crossover as well Kevin Conroy from Batman: The Animated Series set to play future Bruce Wayne. With the stakes being so high I can’t help but hope that some old favorites: Firestorm, King Shark, Jessie Quick etc. make some appearances (different universes and all that). I was really hoping they would end on Arrow because of the clear fate of Oliver Queen but I guess we will have to wait and see.
