Dark Angels Dopplegangers

Dark Angel was an agent of the German Nazi regime who was enlisted to initiate attacks on the American government. This led to her confrontation with Spy Smasher. After this initial encounter in why she was defeated, she declared she would seek revenge against her adversary although if she reappeared she used a different alias. 

Dark Angel filled in a niche that was occupied by Nazi mastermind maidens Paula Von Gunther and Von Gunta, who had opposed the Wonder Women of other Earths. In fact, the alter ego of Dark Angel was Donna Troy, who was connected with the Amazing Amazons.

On Earth-One, Donna Troy was adopted by Queen Hypolyta of Paradise Island, raising the young orphans after the Queen's daughter Princess Diana aka Wonder Woman, who had saved the girl from a raging fire that had decimated the building her parents had resided within. This Donna would become Wonder Girl, a member of the Teen Titans.

On Earth-Two, that version of Donna Troy was rescued from a similar raging inferno by firefighters, and as an older teenage enrolled as a student in Holliday College. She would become a friend and ally of Wonder Woman and her sidekick Etta Candy, as one of the Holliday Girls that shared adventure with them. On one occasion, this Donna adopted a costumed alter ego of Wonder Womam in the fourth dimension.

However, the core Donna Troy of Earth-Seven adopted the alias of Dark Angel, who like her Earth-S was a villain through and through. She would be the basis for a multiverse myriad of malicious maidens. The ultimate fate of the Earth-S Donna aka Dark Angel was to die in a fire, similar to what her counterparts had faced as infants, but instead as an adult.
