Courtney is a former member of the Justice Society of America who operated under the name Stargirl. After being sent back in time to protect a fragment of the Spear of Destiny, she adopted the identity of Merlin in Camelot.


The Justice Society of America meet the Legends

Stargirl and her team confronting the Legends.

After the Legends forced Albert Einstein to reveal Mileva Maric as a ghost collaborator, Stargirl and the Justice Society of America intercepted them, wanting to bring them in for questioning.[1]

The Legends insisted that they knew Rex Tyler though Stargirl said that he never mentioned them. When the JSA insisted that the Legends come with them, things escalated until a fight broke out. Obsidian darkened the skies, as she and Commander Steel was thrown in seeing Martin Stein and Jefferson Jackson merge and take off into the sky. Stargirl finally brought down Firestorm with a burst of energy from her staff, leading to the JSA winning the fight. Holding them in a cell, once they realized that the Legends meant no harm, they allowed them to leave, so long as they never returned. Soon after, when a fight in a Parisian nightclub broke out, the JSA arrived, settling it. The Legends revealed that they had access to a timeship, suggesting that they work together. They headed to the Fontainebleau Forest, intercepting some Nazis and taking on their target, Krieger, just closely escaping, albeit Ray and Amaya getting kidnapped in the process. Eventually taking down Krieger, the Legends handed over the Askaran Amulet to the JSA, who went on their way.[2]

Years later, in 1956, the Justice Society travelled to Leipzig, aided by Rip Hunter, on a mission to recover the Spear of Destiny. However, it was thought to be too powerful for any one person to have so it was decided to break it into four pieces to be split amongst them to protect and scattered throughout time.


Courtney as Merlin.

Courtney took her piece to the year 507, where she created the kingdom of Camelot, assisting its occupants to live a life according to the later Arthurian Ages (rather than the Dark Ages time period they were supposed to have been living in). She hid her shard of her spear in a sword set in stone, becoming the closest advisor of King Arthur known as Merlin. Sometime following, the Legends came to Camelot, much to Courtney's surprise. They took her aboard the Waverider, where she explained how she had arrived in 507 AD. They returned to the court of Camelot, taking part in a feast. Amaya asked for the location of the spear's fragment, but she refused to tell her, promising it was safe. They were promptly ambushed by Damien Darhk, Rip Hunter and a mind-controlled Arthur. Arthur held a dagger to Courtney's neck, before Sara began a fight, causing Arthur to let her go, stopping them all after killing Sir Galahad. After they left, Amaya explained to Courtney that Damien had been working with a speedster, Rex Tyler's killer. That night, Courtney interrupted Amaya and Sara Lance, who had found the fragment of the spear. Although initially refusing to let them go, she let them keep the fragment, asking them to keep it safe. The following day, Courtney took part in the battle, taking on mind-controlled Knights of the Round Table. They eventually gained the upper hand, winning the battle as Damien retreated. Later, the Legends bid farewell, Courtney wishing to stay in Camelot.[3]

According to John Constantine, a mage known as Merlin has created a protection spell in Brythonic language for the use of King Arthur and his knights, allowing him to heal even the worst wounds, a spell he'd later use on Chas Chandler.[4]

DC's Legends of Tomorrow

Season 2


  • While Courtney did share her team's initial view of the Legends being inferior to them since they lacked the same qualifications for crime-fighting, she admitted that she was amazed by their ship.[3]
  • She the sole survivor of her team that protected The Spear of Destiny.
  • Merlin was first mentioned in the shared multiverse by John Constantine, who described an ancient protective spell. It is unclear whether that Merlin was Stargirl, or some pre-existing mage that Stargirl has assumed identity of, as her own vision of Camelot was built from fictional books she had read on the subject.[4]

Behind the scenes

  • In the DC comics, Courtney Whitmore was Stargirl, a member of the Justice Society of America and wielder of the Cosmic Staff, her name a tribute to its original owner, Starman.
