Perdita is a young girl with delicate features. She has green eyes and chin-length blonde hair that is swept back behind her ears. She has dark, arched eyebrows.
Perdita was taken ill and hospitalized at Seattle Medical Center. She required a heart transplant from a donor at Boston General Hospital. Her uncle, Count Vertigo, arranged for five flying ice fortresses to blanket the whole of North America in snow. Kid Flash was given the task of carrying the heart across the country. Vertigo hoped that Perdita would die and he would be made King of Vlatava.
Vertigo's henchman, Henchy, tricked Kid Flash into giving him the heart, but when Kid Flash learned the truth he managed to get the heart back and took it to Dr. Pieter Cross for the operation. It was subsequently announced on the news that Perdita had died on the operating table.
Count Vertigo, now believing himself to be King of Vlatava, spoke with Kid Flash as the young hero was recovering from his exertions. Kid Flash tricked Vertigo into incriminating himself in the attempted murder of Perdita, at which point Kid Flash revealed that Perdita was still alive. Perdita, who had been listening to and recording the conversation, charged Vertigo with high treason and stripped him of his diplomatic immunity. Kid Flash offered her Vertigo's sword cane, but she in turn offered it to Kid Flash as a reward or souvenir.

- The character of Perdita was created by Greg Weisman for DC Showcase: Green Arrow, where she was also voiced by Ariel Winter. The Perdita in Young Justice is a blonde rather than a brunette; she also speaks with a more Eastern European-based accent, akin to her uncle, than she did in the short.
