The CW is giving Arrowverse viewers a treat later this year:
A five-part crossover titled Crisis On Infinite Earths is coming to the small screen, and yes, it's based on Marv Wolfman/George Pérez comic book series of the same name.
With this event bringing together the worlds of several of the network's DC slate of shows, there's been a wealth of information.
As such, we've rounded up everything you need to know about the crossover event of the year.
What is Crisis On Infinite Earths About?
Here's the logline for the comic book iteration of the story.
This is the story that changed the DC Universe forever. A mysterious being known as the Anti-Monitor has begun a crusade across time to bring about the end of all existence.
As alternate earths are systematically destroyed, the Monitor quickly assembles a team of super-heroes from across time and space to battle his counterpart and stop the destruction.
DC's greatest heroes including Superman, Batman, Wonder Woman, Green Lantern, and Aquaman, assemble to stop the menace, but as they watch both the Flash and Supergirl die in battle, they begin to wonder if even all of the heroes in the world can stop this destructive force.
Last year's Elseworlds crossover set up the storyline with Batwoman (Ruby Rose) contacting Oliver Queen (Stephen Amell) to let him know that Dr. John Deegan got a new friend while in Arkham Asylum.
The new friend was none other than Roger Hayden aka Psycho-Pirate from the world of the DC comics.
“Everything is as it should be, the stage is set…,” Hayden, said while wearing the iconic Psycho-Pirate’s golden mask said to Arkham Asylum's newest inmate. “The universe will never be the same.”
During the same crossover event, LaMonica Garrett debuted as The Monitor, and the most significant thing the character did was strike a deal with Oliver to save The Flash and Supergirl who were earmarked for death.
The Monitor popped up to close off the Arrowverse shows to set up Crisis on Infinite Earths during their season finales.
Batwoman Will Have a Pivotal Role
As the new Arrowverse show on the block, Batwoman, starring Ruby Rose as Gotham City's hero will play a big part in the latest crossover.
It's unclear which other Batwoman characters are appearing in the crossover, but given that much of the action will probably be taking place in Gotham City, it would be surprising not to have the regular cast included.
Which Shows Are Part of the Crossover?
Supergirl, Batwoman, The Flash, Arrow, and Legends of Tomorrow will form the five-part event.
Here is the rollout plan:
Supergirl: Sunday, Dec. 8 at 8/7c (special time)
Batwoman: Monday, Dec. 9 at 8 pm (special day)
The Flash: Tuesday, Dec. 10 at 8 pm
Arrow: Tuesday, Jan. 14 at 8 pm (special time)
DC’s Legends of Tomorrow: Tuesday, Jan. 14 at 9 pm (special episode)
Yes, there's a break between the third episode and the fourth, keeping viewers waiting for the answers throughout the holiday period.
From a marketing point, it makes sense. Many shows lose ground in the ratings from their fall finale to their winter premiere, so this will likely help keep ratings strong.
How Does Arrow's Final Season Fit In?
It's sad, but it's true. Arrow is coming to a close after Season 8, which will span just ten episodes.
Given that Oliver seemingly died in the future storyline on Arrow Season 7, it's fair to assume that he gave up his life to restore the balance that the Monitor was talking about during the Elseworlds crossover.
The Monitor did say during Arrow Season 7 Episode 22 that Oliver dies during the crisis. Was that the cost of saving Barry and Kara?
The CW has released the official synopsis for Arrow Season 8.
It says that Oliver “in the wake of discovering what his future holds, will find himself pit against his most challenging battle yet, one that will leave the multiverse hanging in the balance."
"In Arrow’s final season, Oliver Queen is forced to confront the reality of what it means to be a hero.”
Black Lightning Will Enter the Arrowverse During Crisis On Infinite Earths
Since its premiere in January 2018, Black Lightning has stayed well away from the Arrowverse.
In a surprising turn of events, The CW changed course and announced that Black Lightning would cross paths with some of the other DC heroes during the network's day at the Television Critics Association summer press tour in August 2019.
It has yet to be revealed which characters from the series will be crossing over, but it's possible that Black Lightning (Cress Williams) will be the only one stepping away from Freeland for a short time.
Beyond that, it's unclear whether Black Lightning will be part of the Arrowverse permanently following the conclusion of Crisis On Infinite Earths.
There Will Be Two Versions of Superman
Tyler Hoechlin is reprising the role of Clark Kent/Superman during the crossover event. Hoechlin has already appeared in the Arrowverse on multiple occasions as the character.
But there will be more than one Superman as part of the narrative. Brandon Routh, who plays Ray Palmer on Legends of Tomorrow, is suiting back up as the Man of Steel.
Routh previously played the superhero in the 2006 movie, Superman Returns. It has yet to be revealed why two will be part of the crossover, but it's likely they will be from different versions of Earth.
Elizabeth Tulloch will also be returning as Lois Lane, the role she first played during the Elseworlds crossover in 2018.
Bruce Wayne Will Appear
It's confirmed that Bruce Wayne will play a part in the crossover. What's more, Kevin Conroy, the legendary voice behind Batman: The Animated Series will be taking on the role.
The iteration of Bruce Wayne will be from the future, so it's not yet clear how his arrival will shake out for Batwoman.
Burt Ward Will Appear
Ward appeared as Robin during the 1960s Batman TV series, and he will be taking on that role again during the crossover.
