Character descriptions for CBS’ upcoming Supergirl TV series have been released, revealing quite a few intriguing details for the upcoming small-screen comic-book adaptation. Not only that, but they show that there will be some major changes from the comics.

Casting has now begun for Supergirl — and the good casting folks are the same ones who awesomely cast The CW’s Arrow and The Flash — and TVLine have gotten their hands on who the upcoming drama series is looking for to fill its two lead roles.

Here’s the description for Kara Zor-El, aka Kara Danvers, aka Supergirl:

For Kara Zor-El aka Kara Danvers, the show is eyeing Caucasian females, age 22 to 26, to play 24. As the series’ mythology goes, Kara at age 12 was sent from her dying home planet of Krypton to Earth, where she was taken in by the Danvers, a foster family who taught her to be careful with her extraordinary powers. After repressing said skills for more than a decade, Kara is forced to bust out her super moves in public during an unexpected disaster. Energized by her heroism for the first time in her life, she begins embracing her abilities in the name of helping the people of her city, earning herself a super moniker along the way.

The other lead character currently being cast is a major departure from the original comic-book source material. The role is that of Kara’s sister. Yep, you read that right. But she’s not her sister sister. She’s a foster sister. Here’s the description for the character:

The other lead role currently being cast is that of 26-year-old Alexandra “Alex” Danvers, Kara’s gorgeous, brilliant, science-minded foster sister. Growing up, Alex was partly jealous of her sibling yet also fascinated by her abilities, prompting Alex to learn as much as she could about alien anthropology, sociology and culture. Today, Alex works for a secret government organization and, alongside her heroic sis, will face many challenges, both mundane and super.

It’s going to be interesting to see this new take on the Supergirl mythos — with a flying Supergirl, thank you very much! The pilot was penned by Ali Adler (No Ordinary Family) and Greg Berlanti (Arrow). Both Adler and Berlanti will executive-produce the superhero TV show alongside Sarah Schechter (of Berlanti Productions) and Warner Bros. TV.
