Moondragon is a smug, arrogant, self-centered person who will gladly step on anyone in the pursuit of her goals. Cold and calculating, there is, nonetheless, a side to her that very much admires superheroes and wants to be like them. Moondragon’s internal conflict, between her contempt for and admiration of others, often has explosive results.

Alone on the desert, the child was rescued by Mentor, Thanos’s father and the benevolent ruler of the Eternals of Titan who had been monitoring his evil son’s activities. Taken to the settlement of Eternals on Titan, Heather Douglas was placed in the Shao-Lom monastery to be schooled in the arts and disciplines of the ascetic monks of Titan. The Shao-Lom taught her complete control of her body and mind as well as total mastery of her latent psionic potential. She also became an accomplished athlete, martial artist, and geneticist.

Eventually she sensed a malevolent spiritual presence and made psychic contact with it. The presence was that of the Dragon of the Moon, a cosmic entity that claims to have existed before the creation of planets in the cosmos, and to have destroyed entire civilizations. The Dragon existed on Titan before Mentor settled there and claimed responsibility for destroying the Eternals of Uranus who had previously lived there. The Dragon began to take over Douglas’s mind, but aided by the psionic barriers protecting Titan, she drove the Dragon from her mind.

When her studies were finished, she chose “Moondragon” as her name within the order of priests in commemoration of her victory. Her decision shocked the priests. She came to regard Mentor and the entire population of Titan as, in her words, “fools and idiots.” Moondragon was unaware that the Dragon was continuing to influence her subconsciously, and that its goals were becoming hers.

Thanos launched an attack against Titan that destroyed much of its civilization. Fleeing Titan in her own space vessel, Moondragon came to Earth where, under the name Madame MacEvil, she began testing some of Earth’s superhuman champions for possible use in the war against Thanos. She also experimented with the genetic make-up of a number of human beings, using Titanian technology to turn three Earthmen into Angar the Screamer, Ramrod, and the Dark Messiah.

Soon after Thanos was vanquished, Moondragon became involved with the Avengers, but she began to make her feelings of superiority to commonplace humanity (as well as to the majority of the Avengers) known, eventually denying her humanity and claiming to be a goddess. Offered membership in the Avengers, she refused, but she continued to associate with them periodically.

A turning point in Moondragon’s thinking came when she helped the Avengers battle the power-siphoning being from the future Korvac. Scanning Korvac’s mind, she learned of his plan to remake the universe, eliminating all chaos, including free will. When the would-be god committed suicide, she mourned his passing, believing his goals to be correct. She then began devoting her efforts to righting what she perceived to be wrongs by imposing her will upon those individuals and groups who did not conform to her sense of propriety.

She later traveled to the planet Ba-Banis, and used her mental powers to stop their civil war. However, the Avengers traveled to Ba-Banis to stop her. In the process, she took the life of her father, Drax the Destroyer. The Asgardian god Thor turned Moondragon over to his father Odin for punishment.

Odin forced Moondragon to wear a headband that greatly reduced her mental powers. Odin entrusted Moondragon to the custody of Brunnhilda the Valkyrie, a member of the team of superhuman champions known as the Defenders, which Moondragon reluctantly joined. She was again consciously being tempted by the Dragon of the Moon, but she continued to resist it. Despite her initial contempt for the Defenders, she increasingly sought to be accepted by them as a good person. Finally, she and the other Defenders were captured by Asgardian trolls. One of the trolls offered to remove the headband if she would aid him with her psionic powers. The Dragon tempted her with offers of power if she did so. Rejecting the Dragon and her own potential for evil, Moondragon refused to allow the headband to be removed and made it possible for the Defenders to escape. The headband fell from her brow.

Moondragon learned that she was dying. The Dragon of the Moon offered to save her life. As pain over came her, Moondragon became desperate and gave in to the Dragon. Now thoroughly corrupted by the Dragon and endowed with much more power, Moondragon battled the Defenders. The Valkyrie forced her to retreat, but she returned weeks later to destroy the Defenders. The Dragon, persuaded her to turn to the alien Beyonder for the power she needed. The Beyonder increased Moondragon’s power, and she once again attacked the Defenders. She cast the Gargoyle’s human soul from his body, which fell under the Dragon’s control. Interloper, the Valkyrie, and others jointly hurled the power of their life forces against Moondragon, the Dragon, and the possessed Gargoyle. They were all seemingly transformed into statues of ashes and dust, and the Dragon of the Moon apparently disappeared, presumably unable to remain in this dimension without Moondragon. The statue of Moondragon crumbled before the survivors’ eyes. Moondragon survived, now free of the Dragon’s influence.

She was invited to join the Infinity Watch after the Infinity Gauntlet crisis, and given the mind gem by Adam War lock. Whether vast powers will lead to vast corruption, as has happened before with Moondragon, remains to be seen.
