Nickelodeon grad Brec Bassinger will take on the title role in the drama inspired by Johns' late sister.

DC Universe and Geoff Johns have found their Stargirl.

Brec Bassinger, best known for starring in Nickelodeon's Bella and the Bulldogs, has been tapped to play the title role in the streaming service's straight-to-series drama Stargirl.

Stargirl follows high school sophomore Courtney Whitmore (Bassinger) as she inspires an unlikely group of young heroes to stop the villains of the past. The series reimagines Stargirl and the very first superhero team, the Justice Society of America. The character was the first created by Johns in 1999 and launched his career as a comic book writer. He named the character after his sister, Courtney, who died in the 1996 explosion of TWA Flight 800. The character made her first appearance in July 1999's Stars and S.T.R.I.P.E. #1.

"There is no other character in comic books more special to me than Stargirl, and after searching far and wide I can say there is no other actor on the planet that embodies her more than Brec Bassinger. Brec's warmth, strength, humor and positive energy are core to who Courtney Whitmore is. I'm so grateful she's signed on for the role," Johns said.

The character is described as smart, athletic and kind. This high school teenager's seemingly perfect life hits a major speed bump when her mother gets married and her new family moves from Los Angeles to Blue Valley, Nebraska. Struggling to adapt to her school, make friends and deal with a stepfamily, Courtney discovers her stepfather has a secret: He used to be the sidekick to a superhero. "Borrowing" the long-lost hero's cosmic staff, Courtney becomes the unlikely inspiration for an entirely new generation of superheroes.

Johns exec produces the Warner Bros. TV-produced series alongside Greg Berlanti and Sarah Schechter. Johns will pen the pilot.

For her part, Bassinger spent two seasons (39 episodes) starring as Bella in the live-action Nickelodeon comedy Bella and the Bulldogs. Her credits include Hulu's All Night and recurring roles in The Haunted Hathaways, School of Rock, The Goldbergs and Code Black. She filmed multiple pilots and a feature (Liar Liar Vampire) for Nickelodeon. She's repped by CESD, Work Management and Industry Entertainment.
