DC on the CW: Crisis On Infinite Earths poster released

Teased long before all the heroes managed to come to where they are in the Arrowverse, The CW has officially released the poster (via Superherohype) to their newest crossover event in "Crisis On Infinite Earths" - which features The Green Arrow, The Flash, Supergirl, Legends of Tomorrow, Batwoman, and the debuting Black Lightning as he officially joins the Arrowverse line-up for the first time. As the heroes race to save the multiverse from a coming threat, heroes will have to make sacrifices as all life hangs in the balance.

Crisis On Infinite Earths is a five episode event beginning in December and ends in January, running through the five DC on the CW shows.
