Courtney Whitmore

Courtney Elizabeth Whitmore is a superhero appearing in American comic books published by DC Comics. Debuting in Stars and S.T.R.I.P.E. #0 (1999), the character was created by Geoff Johns and Lee Moder. The character's name, appearance, and personality were patterned after Johns' sister Courtney, who died in the explosion of TWA Flight 800 in 1996.

A ordinary teenager who grew up in Los Angeles but moved to Blue Valley after her mother marries her new husband, Patrick "Pat" Dugan, she is surprised to find her seemingly unimpressive step-father was a former sidekick. Soon, she adopted the mantle of Pat's former partner, as the second Star-Spangeled Kid and the pair become a famous superhero duo in the American Midwest, with Courtney known for her youthful optimism. She is later given the codename Stargirl, becoming a successor to Starman and is gifted his cosmic staff. The character prominently serves as a member of the Justice Society of America alongside other teams such as the Justice League and its other iterations.

Stargirl has appeared in Justice League Unlimited, Batman: The Brave and the Bold, Justice League Action, and Young Justice. She has also appeared in live-action shows Smallville played by Britt Irvin, Legends of Tomorrow played by Sarah Grey, and in her own television series played by Brec Bassinger. Bassinger reprised the role for an cameo appearance in the fourth season of the HBO Max series Titans.
