Troia is an olive skinned woman with straight black hair that goes past her shoulders and grey-blue eyes. She has a muscular physique with a full figure. She wears white top with crossed straps over her chest and visible seams. Around her wrist are golden bracelets.
During a meta-human summit in the General Assembly, Troia sided with Atlantean ambassador Garth, who expressed his anger at the increased limitations placed on the Justice League. She argued that heroes would do the right thing, regulations or no. This was met with criticism from Rhelasia's Kaizen Gamorra, who accused her of supporting vigilantes.
- In the comics, Donna Troy was the second Wonder Girl (as Diana used the name as a child), younger sister of Diana, and a founding member of the Teen Titans. She later went by the name Troia, which is her only identity in the show. Her exact backstory has varied in the comics, ranging from an adopted orphan to a magical duplicate of Diana.
- Very early in development, Donna was considered as a leading candidate for the Team in season one, but was quickly removed from consideration for legal reasons. She was later made available, but too late for use in the first season.
- She was planned to appear at Raquel Ervin's bridal shower in "Satisfaction" and the gathering of heroes in "Endgame", but there was not sufficient time to design the character.
- This is Donna Troy's 7th animated appearance. She first appeared in the Teen Titans shorts part of the Superman/Aquaman Hour of Adventure, the Teen Titans TV series, the animated movie Justice League: The New Frontier, the Super Best Friends Forever shorts, the DC Super Friends web series and in the animated movie Teen Titans: The Judas Contract.
