In uniting the Flash, Green Arrow, Superman and more for the 2018 Arrowverse crossover, The CW may soon have their own version of DC's flagship superhero team: the Justice League. The combination of characters who will be present in the crossover strongly resembles the lineup for the Justice League in the comic books.
This year's annual crossover event (which will exclude Legends of Tomorrow) will take place in Gotham City and introduce Ruby Rose as Batwoman. Tyler Hoechlin's Superman, who previously guest-starred in season 2 of Supergirl, will return for an appearance in all three hours of the crossover, along with Lois Lane, who has yet to receive her Arrowverse debut.
The crossover event will include several iconic Justice League members, such as Superman, Flash, Green Arrow, and Supergirl. It should be noted that if all three shows bring along their supporting casts, the heroes will be joined by Supergirl's Martian Manhunter, Arrow's Black Canary, and The Flash's Elongated Man, who are all members of the comic book version of the Justice League. Batwoman was never in the JLA, but could serve as a replacement for Batman, who may not even be mentioned in the crossover.
The Flash star Grant Gustin has already confirmed that his character will share "epic" scenes in-costume with Superman. If we do see all—or even just most—of these characters, the assembled heroes will bear a striking resemblance to the JLA, and may be the closest the Arrowverse will ever get to adapting the comic book team. It should be noted that this year's assembly of heroes is even closer to the JLA than last year's, which included more characters but was missing the Man of Steel.
Having all of these classic Justice League heroes together on the screen at the same time will be a memorable moment for the Arrowverse, whether the "Justice League" name is specifically mentioned or not. Though this may be a one-time-only team-up, the crossover has the potential to lead to something more.
While the formation of an official team would be hard to manage with the characters being spread out across three shows, the crossover could leave the door open for a reunion. The Arrowverse's Justice League can function in a way that's not too different from what Marvel did with The Avengers. Nick Fury brought the Avengers together, but they all went their separate ways at the end of the film. Nick Fury's idea was that the Avengers would return when the world needed them. A similar purpose could be what drives the Arrowverse's heroes to reunite as the Justice League for the annual crossover events in the years that follow.
The Arrowverse crossover will kick off with The Flash on Sunday, December 9, followed by Arrow on Monday, December 10, and concluding with Supergirl on Tuesday, December 11 - all at 8/9c on The CW.
