The Flash: Here's the Final Updated Map of the Arrowverse Multiverse
Earth-Prime
Earth-Prime is still the "main" Earth in the Arrowverse continuity The home of the Flash, Green Arrow, Supergirl, Batwoman, Black Lightning and the Legends of Tomorrow. This is the Earth where, presumably, the final stories for The CW's Arrowverse will take place and is the Earth we know the most about.
prevnextEarth-2
Revealed in the montage at the end of Crisis on Infinite Earths, Earth-2 in the new multiverse is the home of Stargirl. This is the world where Courtney Whitmore and her friends, the new Justice Society of America, are making the world a better place. While DC's Stargirl as a series has ended its run after three seasons, we do at least know a bit about the future of Earth-2, thanks that series' flash forward revealing a future where the JSA are major heroes continuing to protect the world from evil.
prevnextEarth-9
Also revealed during the montage at the end of Crisis on Infinite Earths, Earth-9 is the home of the Titans. That series — which interestingly enough just had its own multiverse crossover of sorts — is currently in its fourth and final season on HBO Max.
prevnextEarth-19
Another end of Crisis reveal, it was previously shown that Swamp Thing exists on Earth-19. Considering that Swamp Thing was cancelled after its first episode had aired and thus only one season exists, we don't really know much about that world — but we hope Swampy is thriving.
prevnextEarth-21
Earth-21 is the home of Doom Patrol. Another end of Crisis reveal, DC's most unlikely heroes are continuing to deal with all matter of weird in over on Earth-21 and currently, they are dealing with the possibility of the end of the world. Like Titans, Doom Patrol is ending this season though the remaining episodes of that series do not yet have a release date.
prevnextEarth-12
Remember the live-action Green Lantern movie? Crisis revealed that Earth is designated as Earth-12.
prevnextEarth-96
One of the more interesting and heartwarming reveals at the end of Crisis was that Earth-96 is the home of Kingdom Come/Superman Returns —the earth where Brandon Routh's Superman lives.
prevnextSuperman & Lois
Fans of The CW got a bit of a surprise at the end of Superman & Lois' second season when it was definitively confirmed that the series takes place on a different Earth form Earth-Prime. This Earth appears to be one where Superman is the only hero (meaning that Flash, Green Arrow, and others don't really exist or are unknown at this time.) Also interesting is that we've already seen alternate worlds within Superman & Lois. John Henry Irons and his daughter come from a different Earth and we've also seen the Inverse Earth, aka the home of Bizarro.
prevnextEarth-4125
The only new Earth we get a specific designation for in "It's My Party And I'll Die If I Want To", Oliver reveals to Barry that Red Death didn't come from another timeline — she was from another Earth in the reborn multiverse and Earth=4125 is its designation. We don't know a lot about that Earth other than its one where there isn't a Batman and the heroes had to come together to stop a rogue Red Death but given that Red Death is currently in ARGUS custody, it's probably safe to say that Earth-4125 is currently a better place than it was.
prevnextSomewhere in the multiverse…
And, since we're coming to the end of our new map — and considering that Crisis did establish that Titans is part of the multiverse, we'd be remiss to not include whatever Earth in the great and wide Multiverse it is that legendary creator Grant Morrison exists in. Morrison made a surprise cameo appearance in a recent episode of Titans when Beast Boy was travelling through the multiverse trying to find his way home. It was a clever nod to the comics and it's kind of fun to think that Morrison is out there in the multiverse somewhere, keeping tabs on it all.
