WB has finally revealed details about this year’s big four-way superhero crossover.

The FlashArrowSupergirl, and DC’s Legends of Tomorrow will join forces in a crossover event called “Crisis on Earth X,” which begins production today. In this year’s crossover, all of the superheroes come to town for Barry (Grant Gustin) and Iris’ (Candice Patton) wedding (sounds like couples therapy ended up working); however, villains for Earth-X crash the festivities with a deadly agenda.

“We conceived this year’s crossover to be evocative of the annual Justice League/Justice Society crossovers we grew up with and looked forward to as kids,” said executive producers Marc Guggenheim and Andrew Kreisberg in a statement. 

To celebrate this two-night event, they commissioned legendary Wonder Woman artist Phil Jimenez to create a custom cover for the event, which is filled to the brim with spoilers.

Based on the poster, we can also infer that the Flash, Green Arrow (Stephen Amell), and Supergirl will be facing off against evil versions of themselves. Moreover, it’s pretty likely that Gustin, Amell, and Benoist will also play their doppelgängers, too, given the fact that Benoist was tapped to voice Overgirl, Supergirl’s evil Earth-X counterpart, on CW Seed’s animated series Freedom Fighters: The Ray. However, that’s not the only connection to Freedom Fighters. The poster also reveals that “Crisis” will introduce the Ray (Russell Tovey, who also voices the character) into the live-action Arrowverse. Captain Cold can be seen in the bottom left corner, which means Wentworth Miller will likely return for the big event, and Zari (Tala Ashe), Legends of Tomorrow‘s new hacktivist from the future, is wearing a mysterious amulet on the cover, too.

“Phil was the perfect choice to bring the comic book cover iteration of this idea to life. You can count on one hand the number of artists who could compellingly represent so many characters in a single image. Phil is one of them. And his design invokes the cover of Justice League #207, which was the 20th Annual JLA/JSA crossover. Our 10-year-old selves are in heaven,” the producers said.

“Some of the first DC Comics I ever read were those insane crossovers with a dozen characters from alternate earths and dimensions — the kind of stuff I later became known for!” added Jimenez. “So when CW asked me to do an homage cover inspired by those amazing team-up covers, I couldn’t resist the chance to draw all of The CW’s DC superheroes in one crazy action sequence.”

The four-way crossover will air across two nights Monday, Nov. 27 and Tuesday, Nov. 28 on The CW. For this crossover event, Arrow will air on a special night Monday at 9 p.m. ET following Supergirl, while the other DC shows will remain in their regularly scheduled time periods.
