Amoral Aviators Agressively Attack Adversaries

Stacy Macklin had been an astronaut trainee as N.A.S.A. at the same time as Diana Prince, the Wonder Woman of Earth-One. On one occasion, while alongside fellow astronaut Brice Rogers, she had been exposed to radiation that years earlier had affected Brice when his space craft passed by a Kryptonite asteroid while in orbit around the moon. 

This had caused Rogers to become the villainous Moonman each time he had been exposed to moonlight as a catalyst. Moonman gained electromagnetic powers, which he used for criminal endeavors. After battling Superman and Batman, Rogers' powers faded and he was cured of his amoral attitudes. He then resumed his military career. 

A similar event occurred on Earth-Two, according to the Essential Batman Encyclopedia, where that world's Brice Rogers as the Moonman had a similar battle with the Superman and Batman of that universe, which resulted in the same outcome.

As for Stacy Maclin’s Earth-Two counterpart, this was the Holliday College student named Gell Osey. When she and her fellow Holliday Girls fraternity were auditioning to be participants in Professor Astronimo’s experimental rocket ship, she failed the aptitude test. Nevertheless, Osey snuck onboard the vessel as it launched into space, seeking glory for herself as a female astronaut. Only through the timely intervention of Wonder Woman was she saved, and repented of her jealous demeanor.

Back on Earth-One, Macklin found herself transformed into the evil Lady Lunar, which empowered her with gravitational abilities allowing her to fly and attract as well as repel objects. She also manifested the ability to alter the perceptions of others, causing those around her to become temporarily insane. Superman and Batman were able to likewise defeat her, she then reverted to normal. However, Lady Lunar reappeared during the Crisis on Infinite Earths 

Returning to Earth-Two, a now reformed Gell Osey joined Etta Candy and her fellow Holliday Girls as they boarded Astronimo’s Super Stratosphere Plane, joining Wonder Woman in protecting their world from an alien invasion. This invasion was launched by Queen Flamina and her maiden minions using devastating superactinic rays on Earth-Two, which Gell and her friends along with Wonder Woman were able to repel. Gell finally earned the honored named of a Holliday Girl!
