Courtney is a former member of the Justice Society of America, known as Stargirl.

Biography
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. Obsidian darkened the skies, leading to a fight between the two teams. Stargirl brought down a flying Firestorm, 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, intecepting some Nazis and taking on their target, Krieger, just closely escaping, albeit with Ray and Amaya kidnapped. Eventually taking down Krieger, the Legends handed over the Askaran Amulet to the JSA, who went on their way.

Years later, in 1956, the Justice Society travelled to Leipzig, aided by Rip Hunter, to recover the Spear of Destiny. Breaking it into four pieces, Courtney took a piece to the year 507, where she created the kingdom of Camelot, as well as its occupants. 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 to be 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, Amay 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 turned 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.
