An unidentified American cosplayer appeared at the 2011 Super Megafest convention, bringing with her all the spandex that comes with Donna Troy, Wonder Girl! (From the Teen Titans in case you were wondering…)
Wonder Girl and the other Teen Titans were next featured in Showcase #59 (December 1965) before being spun off into their own series with Teen Titans (vol. 1) #1 (February 1966). With the character called only Wonder Girl, or “Wonder Chick” by her teammates, her status as either the younger Wonder Woman displaced in the timeline or another character altogether is not explained until Teen Titans (vol. 1) #22 (August 1969).
In a story by Marv Wolfman and Gil Kane it is established that Wonder Girl is a non-Amazon orphan, rescued by Wonder Woman from an apartment building fire. Unable to find any parents or family, Wonder Woman brings the child to Paradise Island, where she is eventually given Amazon powers by the Purple Ray. The story ends with Wonder Girl wearing a new costume and hairstyle, adopting the secret identity Donna Troy.
Or at least, that’s how the original story goes.
Donna’s superhuman powers have changed several times over the years, but in all of her various incarnations, they have always consisted of considerable superhuman strength, endurance, speed, and the power of flight. In her pre-Crisis origin, Donna was granted those powers by the Amazon’s Purple Ray, and these powers increased as she grew older. She also wielded a lasso of her own, but it apparently had no magical properties like Diana’s Lasso of Truth.
