‘Supergirl’ Season 2 Spoilers: Does Kara Have An Earth-1 Doppelgänger?

Fans of CW’s DC TV universe may meet an Earth-1 version of Kara Zor-El (Melissa Benoist) in the future.

Although it’s unclear whether or not Earth-38 Kara has an Earth-1 doppelgänger, executive producer Andrew Kreisberg recently said that he and his fellow executive producers haven’t ruled out the possibility of introducing Power Girl to the universe they have created. “We hadn’t discussed [introducing Power Girl] formally, but I think that certainly after these three [‘Invasion!’] episodes, there’s literally no limit to the things that we can do,” Kreisberg said (via Entertainment Weekly).

In DC Lore, Power Girl, a.k.a. Kara Zor-EL, is Superman’s cousin from an alternate universe. As comic book fans know, Power Girl is slightly older and sassier than Supergirl. Although their superpowers are basically the same, Power Girl has a more revealing costume than the Girl of Steel. In fact, Power Girl is infamous for her costume’s “boob window,” which she uses to distract her enemies in combat.

Power Girl is a member of the Justice League, the Justice Society, Infinity, Inc., Birds of Prey, the Suicide Squad and the Sovereign Seven. The character was created by Gerry Conway, Ric Estrada and Wally Wood and made her debut in “All-Star Comics” #58.

While it seems that fans won’t be seeing an Earth-1 version of Kara anytime soon, viewers can still expect Benoist to appear in future episodes of “Arrow,” “The Flash” and “Legends of Tomorrow,” since her character has an interdimensional extrapolator that allows her to travel between Earth-38 and Earth-1 with ease.

“They’ve gotten to the point we wanted to make [future crossovers] a little bit easier,” Kreisberg said (via IGN) of why Kara’s inter-dimensional extrapolator is an important storytelling device. “The next time we do it, it means it doesn't necessarily have to be because Oliver (Stephen Amell) and Barry (Grant Gustin) need Kara; it could be because Kara needs them. … [The portable breach-opener] just gives us another way to come at a story.”
