Comic book fans are excited and terrified to see The CW tackle this seminal piece of DC history considering how it rewrote history and who died to save the multiverse.
As the "Elseworlds" crossover event wrapped up Tuesday night on "Supergirl," it set the stage for something far worse to come in 2019: "Crisis on Infinite Earths."
Longtime DC Comics fans know that this is the name of the groundbreaking 1985 comic book series that literally rewrote the history of the DC Universe, notably destroying every single parallel world to leave only one universe remaining.

8 Highlights as 'Elseworlds' Crossover Invades 'Arrow': Batwoman, Green Lantern, Batman and More
View StoryConsidering how many universes the "Arrowverse" has come to inhabit, that would be a major status quo change to the DC family of shows on The CW. At the same time, it would be a convenient way for the network to finally have "Supergirl" exist in the same universe as "Arrow" and "The Flash."
Hell, if they were feeling really frisky, they could pull "Black Lightning" in as well for its third season and throw that family for a hell of a loop with the introduction of all these new heroes. As for "DC's Legends of Tomorrow"? Well, that could stick with its time-travel theme, and in so doing could start to uncover this new altered and combined reality.
But is the "Arrowverse" brave enough to go down that path? Many fans were left disappointed with the "Flashpoint" event on the television series, as it was far tamer than the reality-altering comic book event on which it was based. But considering their willingness to alter reality for "Elseworlds," maybe they're bolder than we give them credit for.
But there is another problem when it comes to the biggest "Crisis" of them all. Considering the following a major spoiler alert for the comic book series -- and it was enough to convince some fans they don't want to see The CW even coming close to this story.
Nope. Nope. Don't want this. Nope. Carry that someplace else. Nope. Go away with that. Don't care. Just, nope! Not again. #CrisisOnInfiniteEarths pic.twitter.com/HM9zUyzrvH

The original "Crisis" was so reality-shattering that there were heavy casualties, including both Flash and Supergirl. The Flash was replaced by Wally West in the DC comic book universe, while Kara Danvers simply never existed in the rewritten DCU continuity.
Of course, we could argue that by almost having the pair of them die in tonight's "Elseworlds" finale, the Arrowverse has already paid tribute to their sacrifices in the original "Crisis" and we're good now. Honestly, we don't see The CW stripping their reality of both of these characters, no matter what happens.

6 Highlights from Part 1 of CW 'Elseworlds' Crossover Event as Green Arrow and The Flash Swap Bodies
View StoryAt the same time, Oliver clearly made a deal with the Monitor to save both Barry and Kara from their destined deaths in this episode. The Monitor said their must be balance, so what did Oliver offer? Some fans think he offered himself up as a sacrifice. He's already told the Monitor that he wasn't who he was looking for; he has too much darkness in him.
On top of that, "Arrow" is in its seventh season, so it's possible that either he or The CW are planning his exit from the DCW Universe, maybe to make room for "Batwoman"? Or we're all just totally overthinking this. Even so, he did clearly offer the Monitor something that convinced him to save Barry and Kara. If not himself, what was it?
The wild ending to this year's crossover and big reveal of next year's event had fans both pumped and terrified, keeping #CrisisOnInfiniteEarths trending on Twitter deep into the night. Check out some of their reactions below:

#Elseworlds was one of if not the greatest DC events to ever occur. The fact that this topped #CrisisOnEarthX is ridiculous. I love this universe so much. But after next year, things will never....ever be the same. #CrisisOnInfiniteEarths pic.twitter.com/O7TSSR1nql

Wait, The Flash & Supergirl almost died this crossover but they die in #CrisisOnInfiniteEarths . What deal did Oliver cut ? #Elseworlds
@OneTakeBigDog
Now that it's confirmed, this really is going to be like the Infinity War of the Arrowverse. #CrisisOnInfiniteEarths
@u_faridy
Wait. If Oliver dies in next year's crossover, his absence in the flash forward scenes of Arrow this season make sense. #Elseworlds #CrisisOnInfiniteEarths pic.twitter.com/LKU7yJxsRN

They've been setting this thing up from the beginning. #CrisisOnInfiniteEarths pic.twitter.com/nyDqPgNYzJ

For #CrisisOnInfiniteEarths, I want every DC show to crossover. Flash, Arrow, Supergirl, Black Lightning, Legends, Batwoman. Heck, bring in Titans and Gotham. Add Doom Patrol and Swamp Thing. Have Ezra Miller show up. Bring back @JohnWesleyShipp. Make sure Green Lantern shows up!

So I guess this means that Supergirl's earth will being merging with Earth-1 next season. #CrisisOnInfiniteEarths

@DamnItNora
I am curious though about what will be the end result of next year's #CrisisOnInfiniteEarths event in the Arrowverse. Will Black Lightning be a part of it? Will Kara and Barry have similar fates as their comic counterparts? How many versions will we see? Will the Multiverse fold? pic.twitter.com/pmTHSjHbOD
@nemalki
Okay, so if The CW were to do #CrisisOnInfiniteEarths, I expect fake crossovers like the comics had, where the only crossover element was red skies. Supernatural. Riverdale. Even Dynasty. They all must tie in.
@KSiteTV
Is #CrisisOnInfiniteEarths THE REASON WE HAVENT SEEN OLIVER IS THE FFS? And Dinah said they got the tattoos before “everything happened” AND THAT'S WHY STAR CITY IS LIKE IT IS IN THE FFS?! BC WTF EVERYTHING IS COMING TOGETHER AND STARTING TO MAKE SO MUCH SENSE #Arrow #Elseworlds
