By the end of it, the Arrowverse will not be the same - what a crisis! "Crisis on Infinite Earths" is the sixth annual Arrowverse crossover event, featuring episodes of Supergirl, Batwoman, The Flash, Arrow, and Legends of Tomorrow on The CW. With the first three episodes airing in December 2019 and the last two concluding the crossover in January 2020, this DC television crossover went bigger than ever before. That Film Stew's Luke and Nathan take on this multi-episode superhero epic which continues plotlines established in the previous crossover, "Elseworlds". In "Crisis", the Monitor gathers Green Arrow, the Flash, Supergirl, Batwoman, Sara Lance, Ray Palmer, and several "Paragons" from throughout the multiverse to stop the Anti-Monitor from destroying all of reality.
