As DCTV fans have long been aware, a Crisis is coming, and it’s going to take the combined forces of all the world’s greatest superheroes to save us.

And we do mean all of them.

The CW released the first photos from their upcoming “Crisis on Infinite Earths” crossover event, and fans quickly noticed that there are a few familiar faces standing alongside Barry Allen, Oliver Queen, Kara Danvers, Kate Kane and the other heroes of the Arrowverse. People like Batman: The Animated Series’ Kevin Conroy and Smallville’s Tom Welling. Plus, Tyler Hoechlin and Elizabeth Tulloch as Superman and Lois Lane (with a superbaby!), Audrey Marie Anderson looking far more cosmic than she usually does as Harbinger, and Brandon Routh as a much older, Kingdom Come-like Man of Steel.

These photos are from the first two parts of the five-part “Crisis on Infinite Earths,” so expect more pics in the future. But for now, take a look at these intriguing images, and let us know what you think on Twitter, Facebook and Instagram.

The five-part "Crisis on Infinite Earths" crossover event kicks off on Sunday, Dec. 8 at 8/7c on Supergirl before continuing on Monday, Dec. 9 at 8/7c on Batwoman and Tuesday, Dec. 10 at 8/7c on The Flash. The final two parts will air in January on Arrow and DC's Legends of Tomorrow.
