Over the past few years, The CW have loved to intertwine all of their DC shows both with appearances from certain heroes in other heroes’ series, or by having all of the shows come together in one huge crossover event. And now, we’ve finally been given some information on what to expect for this November’s crossover extravaganza.

If you remember, last year saw Arrow, The Flash, DC’s Legends of Tomorrow and Supergirl smash together to give audiences a brilliant four-part adventure that saw the alien threat of the Dominators causing chaos for our heroes. This year, starting from November 27th, we’ll see another four-parter that has been titled Crisis on Earth-X.

The CW and Warner Bros. Television have revealed the news, with some Phil Jimenez-drawn artwork also released to showcase the event.

On this reveal, executive producers Marc Guggenheim and Andrew Kreisberg said, “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. 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 ten-year-old selves are in heaven.”

The early synopsis for this crossover reads:

With all of the heroes in town to celebrate Barry and Iris’ wedding, villains from Earth-X crash the festivities with a deadly agenda.

While we’ve yet to find out just which villains will be crashing said wedding, we do know of one new addition for the crossover. As per TVLine, Quantico’s Russell Tovey has been cast as Raymond Terrill, aka The Ray. As well as being a part of the crossover, Tovey will also headline the upcoming CW Seed animated series, Freedom Fights: The Ray.

The official description for The Ray reads, “Raymond ‘Ray’ Terrill was a reporter who discovered a group of government scientists working on a secret project to turn light into a weapon of mass destruction. But before he could report on his findings, the project head exposed Ray to a ‘genetic light bomb.’ The bomb failed to kill him and instead gifted Ray with light-based powers. With these abilities, Ray realised he could go beyond reporting on injustice – he could take action to help stop it. Calling himself The Ray, he was recruited by Uncle Sam and the Freedom Fighters to fight violence and oppression wherever it exists.”

In the comic book realm, Raymond Terrill was the second person to take on the moniker of The Ray, debuting in 1992’s The Ray #1. As well as being a huge part of the Freedom Fighters team, Terrill has also been a member of several other heroic teams, most notably the Justice League of America and Young Justice.

As mentioned, the Crisis on Earth-X crossover will begin during the November 27th Supergirl episode, and will then continue later that night with Arrow before wrapping up on November 28th with The Flash and DC’s Legends of Tomorrow.
