15 Mind-Blowing Facts About Supergirl You Need To Know

6. Power Girl Is Actually Supergirl

Even if you're not familiar with this character's history, you'll no doubt still recognise Power Girl. Famous for wearing a ridiculously revealing outfit with a "boob window", she's a fan-favourite superhero, but what you may not know is that she used to be Supergirl! This version of Kara hails from an alternate universe - Earth-2 - and took on the Power Girl moniker after arriving on Earth-1 and seeing that the world already had a Supergirl. That's the origin story of the latest version anyway, but all of the Power Girls we've seen over the years have had the fact that they used to be Supergirl in common. Despite essentially being the same person, Supergirl and Power Girl do look pretty different, with Earth-2's Kara a little older and, well, a lot bustier! Formerly a member of the Justice Society of America, she has all the same powers as her mainstream counterpart, but those are somewhat lowered from being on an alternate Earth. Taking on the secret identity of Karen Starr, she's made a new life for herself in the DC Universe as the owner of her own tech company, and is set to star in a team-up series with Harley Quinn after recently sharing a title with Huntress (the daughter of Batman and Catwoman from the same alternate Earth).
