Since the second season of The Flash, the Arrowverse has played around with the Multiverse concept which is a huge component in the DC mythology. Throughout the last couple of seasons, we have seen the Arrowverse either adapt or name-drop several of the Earths that exists in the larger Multiverse. Some of the Earths that have either been mentioned or briefly seen have sometimes been modified to match the Arrowverse’s Multiverse concept.

One of the bigger examples is that on The CW, Earth-2, and Earth-3 have basically swapped concepts with one another. In the comics, Earth-3 depicts the heroes as the villains while the baddies are now the good guys while on Earth-2, it’s all about the Golden Age of heroes. With the Arrowverse’s upcoming Crisis on Infinite Earths crossover, this would be the perfect opportunity to explore new Earths that have yet to be seen on screen.

The likeliest scenario, if new Earths are shown, is that it would be shown through quick glimpses similarly to when Barry Allen (Grant Gustin) traveled to Earth-2 for the first time. But with that said, here are 10 Earths that we need to see in the crossover.

Earth-42

What is cuter than some of the Funko POP! versions of some of our beloved Arrowverse characters? Chibis or more precisely the Lil’ Leaguers! Since you would probably only be able to pull it off by animating them for this crossover, this would be more like a quick cameo rather than an actual visit to that Earth. But regardless, how cute would it be to see Green Arrow, The Flash, Batwoman, Supergirl, and White Canary in Chibi forms?

Earth-12

While already referenced in The Flash Season 4, viewers never got a clear picture of what Earth-12 is like. In the comics, this is the world where Terry McGinnis a.k.a. Batman Beyond comes from as well as the home of Justice League Beyond. The chances of the Arrowverse doing a straight adaptation of Justice League Beyond are slim, to say the least.

What if in this version we see the children of the Arrowverse having come together in the future as the next generation of heroes? This would be a way to incorporate some of the children we have seen on Arrow and The Flash, but actually working together on this parallel Earth.

Earth-31

Since the Legends of Tomorrow got to have a fun pirate episode in Season 3, why not take it to the next level? Earth-31 is the pirate version of the DC Universe that was led by Leatherwing (Batman) and his crew on the Flying Fox. Imagine the fun of seeing pirate interpretations of the Arrowverse characters, even for just a cameo.

Earth-16

Other than being a side plot in The Chronicles of Cisco, Earth-16 has never been properly explored in the Arrowverse. In the comics, Earth-16 is the world where superheroes are now being worshipped as celebrities. This follows the children of the Justice League whose world is crimeless which boosts the ego of their offsprings.

Since we have seen the Arrowverse introduce some of our heroes’ future children, this would be a hilarious Earth to visit.  How hilarious would it be for our Oliver and Barry to see diva versions of their respective daughters while trying to figure out how things turned out this way on Earth-16?

Earth-33

Earth-1 has had its fair share of magic users such as John Constantine, but that is simply not enough. With the hopes of Constantine participating in the crossover, it would be neat to go to a magical version of the DC Universe. In this case, it would be Earth-33. Imagine if we had magical doppelgangers of the Arrowverse heroes? What would a Green Arrow with magic look like? How would Flash’s speed work? Instead of being a Kryptonian, what would Supergirl be like as a sorcerer?

Earth-29

Even though Crisis on Infinite Earths is going majorly going to be one of the most serious crossovers, we should still have some fun with it. This would be, similarly to Earth-42, something that would act more like a cameo rather than a proper visit. In the DC lore, Earth-29 is better known as Bizarro World. If you thought Bizarro-Superman and Bizarro-Girl were weird, try picture dumb versions of our Arrowverse heroes like Bizarro-Arrow, Bizarro-Flash, Bizarro-Canary.

Earth-23

One of the many Earths that exist is Earth-23 where we have black versions of heroes such as Superman, Wonder Woman, Zatanna and many more. This is, without doubt, one of the most diverse Earths in the DC Multiverse and something that should be explored more in media. Not only that, but this would be a way to incorporate more black heroes into the Arrowverse. For example, since we don’t have a Wonder Woman on Earth-1, what if after the crossover Nubia (Earth-23’s Wonder Woman) becomes a regular character in the new Arrowverse?

Earth-52

For anyone who has watched the Arrowverse shows from the get-go will be aware of the constant usage of 52. From to door signs to street numbers, 52 is a favorite number in the Arrowverse as an homage to its meaning in the DC Universe. So why not reward viewers with a visit to Earth-52 as a way to introduce one of its biggest characters? After a quick name-drop in Season 5, the speedster villain Red Death was referenced as existing in the Scarlet Speedster’s future.

An introduction of Earth-52 in the crossover could introduce the villain as a future threat for Barry post-crossover. Whether it would still be an evil Bruce Wayne underneath that mask remains to be seen.

Earth-22

While we do know that Brandon Routh’s Superman will be Kingdom Come inspired, it has yet to be confirmed if we’ll actually take a trip to that world. In the comics, Earth-22 is where the Kingdom Come storyline takes place. On The Flash, viewers got to see a cyborg version of Harrison Wells whose world is said to be in an endless apocalypse. Even though the number has been used, the Kingdom Come universe is an Earth we absolutely have to see.

Who wouldn’t also want to see retired versions of some our Arrowverse favorites? This could also be where we see Kevin Conroy’s “future Bruce Wayne” show up as it was never specified which Bruce we’ll actually meet.

Earth-11

Imagine a world where Batman and Superman are Batwoman and Superwoman while Wonder Woman is Wonder Man. That is the reality of Earth-11 where its heroes and villains are gender-bent. Given that we’ll have five-hours of this year’s crossover; couldn’t we spend a few minutes on Earth-11?

How fun would it be to see female versions of heroes like Barry, Oliver Queen, Cisco Ramon and many more as well as maybe male versions of Iris West-Allen, Caitlin Snow, Laurel Lance, etc? Since the crossover is most likely going to be very dark for most of the event, having a few minutes of some light wouldn’t hurt.
