Since Legends missed the last crossover I'm glad it's part of this one. It sounds big. I hope they pull it off.
The Legends of Tomorrow might not return with Season 5 until the year 2020, but they will be a part of the Arrowverse’s next crossover.
The CW president Mark Pedowitz announced on Thursday at the network’s Upfront presentation that the “Crisis on Infinite Earths” team-up event will be told in five parts over two quarters — meaning, it will start in December and then conclude early in the new year, following the midseason break.
TVLine has since confirmed with sources that the five shows taking part in the crossover will be Arrow, The Flash, Supergirl, Batwoman (which premieres this fall) and Legends. Three of the five parts will air in December, and the other two — including an episode of Legends, which this year premieres at midseason — will follow in early 2020. (It is unclear at this time what the second show airing its crossover episode in the new year will be.)
