The CW has released the official poster for the upcoming Arrowverse crossover "Crisis on Infinite Earths."

The image is a true who's who of The CW's shared superhero universe, as it features The Monitor assembling John Constantine, Lois Lane (Elizabeth Tulloch), Superman (Tyler Hoechlin), Harbinger, Kingdom Come Superman, Lex Luthor, J'onn J'onzz, Iris West-Allen, The Flash (John Wesley Shipp), Vibe, Black Lightning, Batwoman, Green Arrow, Heat Wave, White Canary, The Flash (Barry Allen) and Supergirl.

Of course, this is hardly all the characters that will appear in the crossover. Those not included in the poster include Ryan Choi/Atom, Clark Kent (Tom Welling), Lois Lane (Erica Durance) Kingdom Come Superman, Huntress (Ashley Scott), The Spectre and even Batman '66's Burt Ward in an undisclosed role. That said, it stands to reason that, while those featured in the image will play significant roles in the crossover, the ones excluded will likely only make cameo appearances.

"Crisis on Infinite Earths" begins Sunday, Dec. 8 on Supergirl, then continues in Batwoman on Monday, Dec. 9, and then picks up in The Flash on Tuesday, Dec. 10. After a winter hiatus, the crossover concludes on Tuesday, Jan. 14 on both Arrow and DC's Legends of Tomorrow.
