As if the real world weren’t increasingly rife with Nazis, the Arrow-verse has a whole planet full of them. See the forces of “Earth-X” invade Barry and Iris’ wedding with a full trailer for the four-way crossover event between Supergirl, Flash, Arrow and Legends of Tomorrow.

Following the giant photo-bomb from all four episodes, The CW released a full three-minute trailer for the November 27-28 event, which follows a “Crisis on Earth-X” emerging on all four series by way of Barry and Iris’ wedding. There’s Nazi Supergirl, Nazi Green Arrow and more (guys, maybe this wasn’t a great idea), while the footage also curiously notes that Earth-X is a fifty-third earth not previously known to the multiverse.

Beginning with Monday’s Supergirl and Arrow, and concluding with Tuesday’s Flash and Legends, here’s the full synopsis for all four nights:

Barry (Grant Gustin) and Iris’s (Candice Patton) wedding brings the gang together, but things go awry when villains from Earth-X attack the ceremony. All of the superheroes band together with help from their super friends like Citizen Cold (guest star Wentworth Miller), The Ray (guest star Russell Tovey), Felicity Smoak (Emily Bett Rickards), Iris West and Alex Danvers (Chyler Leigh) to take on their most formidable villains yet. Earth’s mightiest heroes — Green Arrow (Stephen Amell), Supergirl (Melissa Benoist), The Flash (Grant Gustin) and White Canary (Caity Lotz) — lead their teams into battle to save the world.

The event will also feature Russell Tovey’s Raymond “The Ray” Terrill, an alternate-Earth Prometheus and one of Wentworth Miller’s final appearances in the franchise. Stay tuned for more as we begin the countdown to “Crisis on Earth-X.”
