Four dramas linked together in "Crisis on Infinite Earths" and the crisis seems to be very serious

The CW's latest crossover series "Crisis on Infinite Earths" has released a new trailer, and we can feel the despair of this world. In this universe, Supergirl is sad about her failure, heroes from other universes warn of the coming disaster, and the Earths of other parallel universes are being destroyed one by one. In short, it seems that the Earth is doomed again. Oh, and Kevin Conroy shows up.

Among all the promotional materials released for Crisis on Infinite Earths, this trailer is the most intriguing. Even Batman, who has been silent for many years, has made a grand appearance.

Can our hero save the world this time? I guess so, but at what price? What kind of process will it take? "Crisis on Infinite Earths" is about to be aired, so fans should stay tuned.
