Moondragon, aka Heather Douglas, was created by Bill Everett, Mike Friedrich, and George Tuska. She made her first appearance in Iron Man #54. While driving through the desert with her mother and father (who later became Drax the Destroyer), they came across Thanos, who blew up the car, killing both parents, but miraculously, Heather survived. She was discovered by Thanos’ father, Mentor, who cared for her on his home world, Titan.
While on Titan, she was trained by monks to be proficient in several martial arts. She was also able to tap into her psionic abilities. Through rigorous training, she was able to surpass the monks who trained her. She then accidentally made contact with a being known as the Dragon of the Moon with her new mentat abilities. The Dragon attempted to corrupt her, however she was able to defeat it and took the name Moondragon. Unbeknownst to her, the Dragon still maintained a subconscious influence on her.
Over the years, she has reluctantly found herself a member of the Infinity Watch, the Defenders, and the Avengers before becoming a Guardian of the Galaxy. Moondragon is openly bisexual and has found herself attracted to Daredevil, Quasar, Phyla-vell, but most popularly, Thor, who she mentally enslaved to be her lover.
Along with her extreme proficiency in hand-to-hand combat, Moondragon’s powers include telepathy and minor telekinesis.
