Wonder Girl

Donna joined other young heroes—Robin, Aqualad (Garth), Speedy (Roy Harper), Kid Flash (Wally West), and Robin (Dick Grayson) as the Teen Titans. Though the team dissolved, Donna joined the second incarnation, which added Raven, Cyborg, Starfire, and Beast Boy. They battled the Titans of Myth when one of them, Hyperion, mind-controlled Donna to fall in love with him and tried to take her for a bride while the Titans tried to overthrow Olympus. Later, Robin helped Donna find answers about her past, and she was reunited with her adoptive mother, Fay Stacey, who had remarried and had a family. Fay and her family welcomed Donna as one of them. Donna fell in love with Terry Long, a history professor, and they eventually married.

Donna again encountered the Titans of Myth when she battled one of the Titan Seeds, mortals the Titans had empowered. One of them, Sparta, was killing others in order to get all their powers before destroying the Titans. After defeating Sparta, Donna was given new powers by the Titans of Myth as thanks. To reflect this, she took the code name Troia. Later, Donna became pregnant with a son, but heroes from the future called Team Titans reported he would be born with godlike powers and become a mad conqueror. To prevent this, Donna gave up her powers. She joined the intergalactic police force called the Darkstars, acquiring an exo-suit that allowed space travel. Following attacks by several enemies, Donna and Terry divorced when Terry felt Donna's presence was too dangerous for their son.

Donna dated the new Green Lantern Kyle Rayner for a time, but when her ex-husband Terry and son Robert were supposedly tragically killed in a car accident, she ended that relationship. Later, Donna faced the Dark Angel, an old enemy of Hippolyta, who revealed that many years ago, she had cursed Donna to periodically have her life reset so she could never know true happiness. With the help of Wally West and Wonder Woman, Dark Angel was defeated, the curse broken, and Donna's powers restored. Hippolyta formally named Donna a princess of Themyscira, and Donna became more involved in the island's affairs. She became a moderator between longtime Themyscirans and the more recently arrived Bana-Mighdall tribe. Donna played a key role in the Infinite Crisis, becoming a guardian of the history of the Multiverse.

When Wonder Woman decided to take some time off, Donna stepped into the role for a year. A group of Wonder Woman's enemies captured Donna to lure Diana into a trap. Diana, several Teen Titans, and other allies rescued Donna and defeated the villains, who were led by Circe. Donna asked Diana to resume the role of Wonder Woman, which she had never felt comfortable in. She decided she preferred to just be called Donna Troy. Donna later joined the Justice League, along with several other former Teen Titans, including Cyborg and Starfire. That incarnation of the League later disbanded, and Donna and the other former Titans opened Titans Academy, where they would train the young heroes of tomorrow.

Donna's confusing origins became even more so when she learned she was originally made from clay by a sorcerous enemy of the Amazons to kill Wonder Woman. However, the Amazons discovered the plan and instead gave Donna different memories (the ones of being rescued from a fire by Wonder Woman), adopting her as one of them to give her a chance at a different life. But Donna later discovered that wasn't true and that her original memories were the accurate ones. After so many twists and turns in her life and her past, Donna has come to value her present. She doesn't worry as much about who she was; rather, she is at peace with who she is. She values her loved ones, cherishes every moment with them, and will face any odds for them. That, she knows, will never change. That's who Donna Troy is.
