Donna Troy (Conor Leslie)

Donna Troy is a photographer and the childhood best friend of Dick Grayson, as well as Wonder Woman's former protégé Wonder Girl. She is played by Conor Leslie.

At a very young age, Donna had a traumatizing experience involving a fire. She was found by Diana Prince, also known as Wonder Woman, and taken to the Themyscira, where she was trained in the ways of the Amazons. Sometimes, Diana would attend Justice League business at Wayne Manor and would bring Donna to accompany her. At some point, Donna met Dick Grayson and the two formed a sibling-like bond. She would often offer him advice whenever things seemed too complicated or stressful for him.

Over the years, Donna eventually stopped training under Diana and followed her own path as a photographer, and to fight crime her own way.
