Are you ready to meet DC’s next live-action star? In 1999, Geoff Johns created Courtney Whitmore as a tribute to his late sister, and Stargirl has since gone on to become one of the DC Universe’s most endearing characters. To know her is to love her. So, let's get to know her!

Her Series Has an All-Star Cast

There are plenty of reasons to be excited for the Stargirl series, especially after you get a look at its all-star (no pun intended) cast! Luke Wilson will be portraying Courtney’s stepfather Pat Dugan; and yes, he will be piloting S.T.R.I.P.E. Amy Smart will play Courtney's mom Barbara. Lou Ferrigno Jr, son of the legendary Hulk actor, will be bringing Hourman to life. Henry Thomas, best remembered for his role as Elliot in E.T., will be playing Doctor Mid-Nite. Need more? How about Joel McHale as Starman? If you’re a Justice Society fan, you’ll be seeing lots of familiar heroes and villains.

She Wasn’t Always Called Stargirl

You remember what it’s like to be a teenager. Sometimes you try out different personas to see what fits. When Courtney Whitmore first suited up in Stars and S.T.R.I.P.E. #1 she decided to call herself the Star-Spangled Kid. Initially Courtney had worn the outfit to annoy her stepdad (who was once the superhero Stripesy), but when her school dance was invaded by criminals, she leapt into action and a new hero was born.

To everyone’s surprise, Courtney excelled at superheroics. She even caught the attention of Jack Knight, who passed on his Cosmic Staff to Courtney when he retired the Starman identity. By 2003’s JSA: All Stars #4, Courtney decided that she had outgrown her old codename and chose to honor the legacy of the heroes who inspired her by taking on the name Stargirl! Some teenagers change their profile pictures or usernames on a weekly basis, but Courtney knows a good name when she sees it. Stargirl has remained her moniker to this day.

She’s Been a Part of Some Powerhouse Teams

Courtney Whitmore can be described many ways, and shy isn’t one of them. She’s a social butterfly, making friends wherever she goes, and that includes the superhero community. Initially, she fought crime alongside her stepfather Pat Dugan, who piloted a giant battlesuit called S.T.R.I.P.E. Having your stepdad follow you around on patrol can cramp your style, but it actually helped the two of them bond.

Later, Jack Knight vouched for Courtney and encouraged the Justice Society to let her join the group in 1999’s JSA #4. Stargirl quickly bonded with the group and found herself a mentor in Power Girl. She also made the cut for the Justice League in 2013’s Justice League of America #2. Most teen heroes would be lucky to get an internship with the Legionnaires or the Teen Titans, but Stargirl has an all-access pass to some of the biggest teams in the DC Universe!

She Has a Good Dental Plan

Being a superhero is hard enough, but don’t forget Courtney is also a teenager, which comes with its own set of problems. Courtney deals with many of the trials and tribulations of adolescence, including braces. How many superheroes can you think of that have a mouth full of braces? Courtney was mortified to receive hers in Stars and S.T.R.I.P.E. #2 and tried to hide her new smile from her Blue Valley High classmates. It’s so embarrassing, it just makes you want to die!

Most of Courtney’s friends and superhero allies thought her smile was still beautiful, but she wasn’t having it. She looked forward to the day she could get her braces off, and the entire Justice Society wanted to be there to support her. Naturally, Stargirl was mortified when they all accompanied her to the orthodontist appointment in 2009’s Justice Society of America #26. Even worse, Courtney was told that her braces would have to remain for another year. Bummer! Don’t worry, Stargirl, Halo was also embarrassed by her braces too.

She’s Been in Another DC Universe Series

If you’re a DC Universe subscriber, there’s another place you can find Courtney Whitmore. The camera-ready character can be seen throughout the season in Young Justice: Outsiders, where she is played by DC Daily host Whitney Moore. The Young Justice version of Courtney is a bit older, and hosts her own entertainment show, appropriately titled “Stargirl.” Although she isn’t a superheroine yet, there’s no telling what fate future seasons hold for her.

If you’re hungry for more animated takes on Stargirl, check out the Justice League Unlimited episode “Patriot Act” and the Batman: The Brave and the Bold episode “Cry Freedom Fighters.”

Keep your eyes on both and for more Stargirl news and features. In the meantime, if you want more Courtney, be sure to grab the new Stargirl by Geoff Johns collection that’s in stores tomorrow. It features some of her best adventures by the person who created her (and is overseeing her TV series). Once you’re done reading that, you’ll know Courtney so well, you’ll practically be besties!

Stargirl debuts today on DC Universe and tomorrow at 8 p.m. (7 p.m. CST) on The CW. Visit our official Stargirl page for more news, videos and features on DC's newest small screen hero.
