DC & Warner Bros' three-part Justice League: Crisis on Infinite Earths animated series starts airing from early 2024, following the events of 2020's Apokolips War, and John Constantine in the House of Mystery 2022. The show depicts a Multiverse reality in which hundreds of Earths exist in parallel; each Earth has superheroes with the same name, same abilities, but somewhat of different personalities and fates. Upon learning about the existence of the Multiverse, the heroes seek to connect with each other; but that is also the time when they face the truth that the infinite Earths would inevitably perish.
