We’ve known for a little while now that this year’s annual Arrowverse crossover event was set to see a trip to an alternate Earth for our heroes, but now we’ve finally been given the official synopsis for said crossover.
As per The CW, the official blurb on the event – titled Crisis on Earth-X – reads:
Barry and Iris’ 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, The Ray, Felicity Smoak, Iris West and Alex Danvers to take on their most formidable villains yet. Earth’s mightiest heroes – Green Arrow, Supergirl, The Flash and White Canary – lead their teams into battle to save the world.
Over in the US, the crossover is set to launch on November 27th with Supergirl. From there, the tale will continue to play out on Arrow, The Flash and finally DC’s Legends of Tomorrow. Given how we’re a week behind US viewers here in the UK, expect the crossover to commence from December 4th over here on Sky1.
