There’s a lot we still don’t know about this year’s Arrow, Supergirl, The Flash DCTV crossover event, “Elseworlds,” one thing readers are pretty clear on is what that title is a reference to. “Elseworlds” is the name of a popular line of comics from DC’s past that completely reimagined the worlds of DC’s greatest heroes. It’s a part of the company’s legacy, something that’s nodded to in a unique new image that’s promoting the three-night event.

Drawn by comic book artist Amy Reeder and designed to look like the cover of one of DC’s monthly comics, this illustration also includes the classic, all-lowercase “Elseworlds” logo. With LaMonica Garrett’s Monitor seen looming in the background, Reeder’s illustration portrays the heroes of the crossover—Green Arrow, the Flash, Supergirl, Superman and Batwoman—seemingly battling each other. Beneath them, Jeremy Davies’ maniacal-looking Dr. John Deegan can be seen looking up at them in delight, suggesting he might be the cause of the mayhem. Fans will also notice that the Flash in the image is actually Stephen Amell, while Green Arrow is Grant Gustin—something already teased through photos.

Reeder has drawn several highly regarded comics for DC, including the bestselling New 52 Batwoman series, which helped to define the Kate Kane version of the character.

Look for the “Elseworlds” crossover event to kick off on Sunday, December 9 at 8 p.m. (7 p.m. CST), then continue at the same time on December 10 and December 11 on The CW.
