How Supergirl's Earth-1 Counterpart Could Appear On The Flash

Now that Greg Berlanti and the rest of the DC TV creative team have looped Supergirl into the mix, the sky is the limit for what could happen in the future, and that’s not limited to just Earth-1’s sky, either. Even before The Flash’s trip to National City happened, fans were talking about whether or not Supergirl could head to The Flash’s universe in the future. But what about an Earth-1 doppelgänger for Kara Danvers? Here’s what executive producer Andrew Kreisberg says.

Any Kara that exists on Earth-1 would also have to have been an alien. It can’t just be Kara Danvers from Poughkeepsie.

I’m sure Poughkeepsie residents aren’t too pleased to hear that they couldn’t be the home of Earth-1 Kara Danvers, but perhaps they’re okay with not being the first place in the world where an actual alien has been proven to exist. All those tourists!

Back to Central City. Of all the weirdness that The Flash has given us – and that includes your basic metahumans, your giant animal metahumans, your multiple dimensions, your ghoulish time wraiths and more – the show still hasn’t really looked into space for its science fiction angles. And while a visit to Earth-1 from an extraterrestrial wouldn’t necessarily have to show anything from space, I kind of wish there were some galactic elements to this show in the future.

A doppelgänger of Kara showing up on Earth-1 would be headline news to the rest of the world, but I’m betting it would happen in such a way that only the S.T.A.R. Labs team would find out about it. I can just see Cisco’s face now as he humbly but excitedly asks Kara to do experiments on her with whatever alien-examining device he invented just minutes before she showed up.

When asked by EW, Kreisberg interestingly teases that another world’s version of Kara could also have some superpowers.

Sure, different costume, but sure.

Yes, it’s likely that another version of Kara wouldn’t have the same Kryptonian history, meaning the ”S” on her costume wouldn’t have the same familial symbolism. Plus, what if capes are not as in vogue on other versions of Earth? I’m pretty sure Cisco would also have a device for that, too, although maybe Caitlin would be better suited for something that’s both well-designed and fashionable.

Kevin Smith, who is directing an upcoming episode of The Flash, recently talked about what fans can expect from Supergirl over its final episodes, but he also mentioned that the producers were talking about that Flash crossover being the first of many for the Girl of Steel. I assume these shows’ brainstorming sessions are out of this world, literally, and that Berlanti & Co. will eventually figure out a perfect way to get both Supergirl proper and Earth-1 Kara into the narrative before another season has passed.

In the meantime, Flash fans can get ready for a wacky crossover in the coming weeks that ties into Arrow’s latest shocker. Find the Scarlet Speedster on Tuesday nights on The CW, while Supergirl airs Monday nights on CBS.
