Courtney Whitmore is the main character in The CW and DC Universe series, Stargirl.

Courtney is a sophomore in high school whose life in Blue Valley, Nebraska takes an unexpected turn when she discovers a powerful staff. She soon rallies together an unlikely group of young heroes to continue the legacy of the Justice Society of America.

Courtney is the superheroine known as Stargirl and the current wielder of the Cosmic Staff.


Courtney's smooth-going high school experience is derailed when her mother marries and moves the household from Los Angeles to bucolic Blue Valley in distant Nebraska. Struggling to adapt, Courtney discovers her stepfather has a secret past as a superhero sidekick. She also discovers an artifact of immense power, a long-lost hero’s cosmic staff, and Courtney becomes the unlikely inspiration for an entirely new generation of superheroes.


Courtney is a complicated young girl whose disposition and nature was greatly affected by her mother's marriage to Pat Dugan and their subsequent move to Blue Valley, causing her to lash out her negative feelings. She detested her new stepfather and initially dismissed him as lame, refusing to acknowledge him as her new father figure as she secretly held out hope her biological father may soon return one day. Following the move, she struggles to assimilate into small-town life and the typical teenage problems of socially navigating high school as a friendless new student. Her first encounter with Brainwave revealed her subsequent feelings of being alone and isolated. She also harbors many unresolved issues from her father abandoning her.

Despite this, her short temper and the fire within her leads Courtney to defend those who are being bullied. She isn't afraid to stand up for herself. Instead of being frightened of the impossible sight of the Cosmic Staff, Courtney demonstrated a curious, brave side of her which was a factor of her succession as the new handler. She was chosen by the staff for her remarkable heart and enthusiasm to fight for justice. Even when things seem lost, Courtney manages to find her way back to the ideology of justice and heroism. She can be overly enthusiastic and didn't understand the full depths of being a superhero until the death of a fellow student finally taught her the consequences the life can have. Even when faced with grief, Courtney was able to convince Pat that it was because a kid died that they had to continue their mission.


The night the Justice Society of America fell Christmas Eve ten years ago, Courtney Whitmore was just a five-year-old girl staring out her apartment window, waiting for her father to arrive to give him her gift. Barbara, needing to go to work, enlisted her friend Miss Kramer and her daughter Mary in charge of Courtney. She cried to her mom that she wanted to see her daddy. Barbara attempted to steer Courtney's mind to see the positive before heading out. She watched her mother leave outside.

In the present day, a now teenaged Courtney is packing up her bedroom for the big move, finding that same gift for her father on a shelf. She puts it in a box as Mary approaches, telling her she'll miss her. The two friends embrace sadly until their attention is turned to Pat arriving outside. Mary notes her new stepfather, but Courtney coldly states he is not her father and blames him as the reason she's being uprooted from her life. Subsequently, she ignores his offer to help carry boxes, which is observed by Barbara, who tells her Blue Valley is where she grew up and the couple made the choice to move together. Courtney and her blended family later arrive at their new house, with her viewing the sight with contempt. She stares at a box labeled auto parts as they head into town to eat.

Courtney's weirded out by the kind gestures of the residents as they stumble upon the diner where Pat and Barbara met two years ago. Courtney asks why Pat was in Nebraska, where Pat ominously replies he was looking for something.

The next morning, Pat drives Courtney to her first day of school at Blue Valley High School, whose texting with Mary. He tries to break in the car by telling a personal story on the value of friends but Courtney is unmoved. They arrive, at Pat bids his stepdaughter a great day to her annoyance. She cautiously walks down the crowded school hallway to the school's office and is later angered that the school gymnastics team has been recalled due to budget cuts, but is informed that cheerleading is an option.

Courtney disgustingly looks at her new school ID before meeting Cindy Burman and her friend Jenny. Quick to get to know the new girl, Cindy announces they should all hang out. Courtney becomes enlightened, and begins to tell her phone number but Cindy says she already has it. She says she should try out for cheer leading, but Courtney rejects her offer. Cindy quickly and asks if she didn't want to meet up. Courtney clarifies it wasn't what she meant, and Cindy replies that she'll text her or not.

In the crowded cafeteria, Courtney looks around for a seat when Paula Brooks confronts her. She asks if she needs a seat, and directs her to a mostly empty table. Courtney thanks her and introduces herself to the three, with a girl named Beth being the only one to warmly respond back. Trying to break the awkward silence, she's informed by Beth that they're not all friends and she's basically at the loser table. Two jocks come on either side of the remaining girl, with the redhead taunting her if she has any new pictures of herself. Courtney tells him to leave her alone. The redhead jock takes her phone, asking if she has any. Courtney pushes him on reflex, causing him to knock into a cafeteria lady and spilling much food on the floor. The principal tells Courtney to come with her, as Cindy slyly calls her a bitch and that was her boyfriend.

Courtney lands in detention with the boy from the table, which causes her to miss her bus after school ends. She is forced to walk home, but the sight of a father and his young daughter distracts her along the way.
