'Crisis on Earth-X': A Guide to The CW's Four-Way Crossover
This season's DC TV crossover is bigger than ever.
The tradition of uniting The CW superhero dramas Supergirl, The Flash, Arrow and Legends of Tomorrow has grown exponentially, as showrunners of all four shows opted to make the crossover a proper four-hour event, introducing new world filled with new superheroes, all while celebrating the wedding of Barry (Grant Gustin) and Iris (Candice Patton).
Of course, there can't have a TV wedding without something going wrong, and in this case, Nazis attack just as the superfriends gather for the nuptials. The Nazis come from an alternate universe, a 53rd Earth called Earth-X, where Germany won World War II.
With so many new and familiar faces taking on different roles as evil doppelgangers run amuck, The Hollywood Reporter has compiled a primer for the crossover. Here's the complete guide to this year's four-show crossover, "Crisis on Earth-X."
When will it air?
The crossover begins Monday at 8 p.m. with Supergirl and continues at 9 p.m. with Arrow. The action picks up again Tuesday at 8 p.m. with The Flash, before concluding at 9 p.m. with Legends of Tomorrow. Since Arrow is moving from its usual Thursday at 9 p.m. slot for the crossover, there will not be a second episode of the Stephen Amell starrer this week.
Who is that in the gold helmet?

Last year's Arrow-verse crossover "Invasion!" was technically a four-show, three-episode crossover. This year is actually a five-show, four-episode crossover as CW Seed's upcoming animated series Freedom Fighters: The Ray star Russell Tovey will bring his animated Raymond "Ray" Terrill character into live action for the big event. Ray is an openly gay superhero fighting with the Freedom Fighters, a superhero team from an alternate world where the Axis won World War II.
Before gaining superpowers, Ray was a reporter who discovered a group of government scientists working on a secret project to turn light into a weapon of mass destruction. Before he could report on his findings, the project head exposed Ray to a "genetic light bomb." While the bomb failed to kill him, it gifted Ray with light-based powers. Calling himself The Ray, he was recruited by Uncle Sam and the Freedom Fighters to fight violence and oppression wherever it exists. Tovey (Quantico, Looking), will voice Ray for the CW Seed series after his live-action debut.
Why is Supergirl evil?
Get ready to see double during the crossover when doppelgangers of some of the fan-favorite Arrow-verse characters arrive. Some are aligned with the Axis, while others will team to fight with the heroes. In the extended crossover trailer, viewers meet Overgirl (Melissa Benoist), an evil version of Supergirl, along with Earth-X's Dark Arrow (Amell), Thawne aka Dark Flash (Tom Cavanagh) and Citizen Cold aka Leo-X (Wentworth Miller). While most of the doppelgangers are all evil versions, Citizen Cold is actually the heroic counterpart of Captain Cold and will join with Oliver, Barry, Kara, Sara (Caity Lotz) and the rest of the Earth-1 heroes to fight the Nazis. An Earth-X version of Prometheus will also show up, but it won't be Adrian Chase (Josh Segarra) underneath the hood. It hasn't been revealed who will be playing the new version of that villain.
Supergirl's Jeremy Jordan will also get in on the doppelganger fun, playing a dark version of Winn Schott on Earth-X. While Killer Frost (Danielle Panabaker) can be seen in the trailer, that is actually Earth-1's version of Caitlin Snow, who is learning how to control and use her powers without going full villain.
Who wasn't invited?
While some heroes like Ray Palmer didn't score an invite to the big wedding, most of the Arrow-verse heroes will join in the crossover fun throughout the four episodes. However, some had to sit this year out. The Flash's Ralph Dibny (Hartley Sawyer) and Supergirl's J'onn J'onnz (David Harewood) and Lena Luthor (Katie McGrath) will not be in this year's crossover, so don't expect them to pop up in the later episodes.
