The CW has confirmed the five-hour Crisis On Infinite Earths crossover will consist of Arrow, The Flash, Supergirl, Legends of Tomorrow, and Batwoman.
The network also revealed the Crisis On Infinite Earths crossover will air over two quarters, meaning the event will likely consist of midseason finales and midseason premieres for the Arrowverse shows. The Crisis On Infinite Earths episode of Arrow may also serve as it’s series finale considering the show is set to return for a 10-episode final season in fall.
The Crisis on Infinite Earths event has been teased since the pilot episode of The Flash, where a newspaper headline from the year 2024 revealed the Scarlet Speedster is fated to disappear during a “crisis.” However, the fifth season finale of The Flash set up the early arrival of the crisis when the original newspaper from the future suddenly changed the date of the event from 2024 to 2019.
