Created by Bill Everett, Mike Friedrich, and George Tuska,[1] the character first appeared in Iron Man #54 (January 1973).

[2] She has achieved her extraordinary talents strictly through extreme degrees of personal regimen,[3] unlike most Marvel characters who have gained their paranormal abilities through birth or accident.

Moondragon debuted in Iron Man #54 (January 1973), created by Bill Everett, Mike Friedrich, and George Tuska.

When Heather was still a girl, her father was driving her and her mother through the desert when they accidentally happened to see the spaceship of Thanos land; the space villain did not want any witnesses, so he destroyed their car.

[24][25] When the Avengers confront Korvac, Moondragon’s powers allow her to see into his mind, and she decides that his goal of saving the universe by ruling it is noble.

[26] Moondragon leaves Earth with Drax and finds a planet immersed in war, so she decides to take mental control of all its inhabitants to force them to live in peace, setting herself up as their "peace goddess.” Drax summons the Avengers to intervene and in the resultant confrontation, Moondragon is forced to kill her father with her mental powers.

Now totally corrupted, Moondragon battles the Defenders until Andromeda, Interloper, Manslaughter, and Valkyrie sacrifice themselves to kill both her and the Dragon.

[31] Heather's soul manages to survive, and, now free from the Dragon again, contacts her cousin Pamela; through her, she is able to obtain a new body for herself, a clone created on Titan.

[volume & issue needed] Moondragon later becomes an associate of Genis-Vell (the third Captain Marvel), determined to help him control his cosmic awareness.

Also, when she is infected with the Annihilation Wave parasites, she is forced to reveal Annihilus' plan to destroy all life in the universe, which he would then rule.

[volume & issue needed] In Quasar: Annihilation: Conquest, the love of Phyla and Moondragon is explored in depth.

[38] After her resurrection, Moondragon joins Phyla back at Knowhere and is accepted as an unofficial member of the Guardians of the Galaxy.

[volume & issue needed] With Phyla's death at the hands of Adam Magus, Moondragon takes it upon herself to become a field agent for the Guardians of the Galaxy.

However, she becomes host to an alien parasite originating in a parallel universe across the Fault, a time-space tear created by Black Bolt's Terrigen Bomb.

To make things worse, members of the Church of Universal Truth kidnap Moondragon and Cynosure, seeing the parasite as a god, whom they intend to birth.

[40] Heather Douglas is a human who has accessed her full psionic potential through extreme training under the Titanian monks of Shao-Lom.

Moondragon primarily possesses tremendous telepathic abilities,[41] which have enabled her to control the population of an entire planet to stop an ongoing war, while enslaving the thunder god Thor as her personal lover.

She is also a low-level telekinetic, an ability that lets her move and manipulate most physical matter by using only her thoughts, levitate herself and others, create shields of psychic force, and fire concussive psychokinetic energy blasts with sufficient strength to affect steel.

She has demonstrated the ability to assume the form of her namesake, a fire-breathing dragon capable of surviving in outer space, traversing interstellar distances.

[37] Moondragon has undergone extreme levels of training in the Titanian martial arts, as well as mental disciplines allowing her near-complete control over her body, including autonomic functions such as heartbeat, bleeding, and breathing, as well as awareness of pain.

[47] She possesses a genius intellect and is extremely knowledgeable in various areas of advanced Titanian scientific disciplines, such as genetics and bionics, and has been able to upgrade the cyborgs Ramrod and Angar the Screamer.

[18] George Chrysostomou of Den of Geek called Moondragon one of Marvel's "fan favorites," writing, "Heather Douglas is a fascinating figure and it’s an absolute crime that she is yet to be introduced to the MCU.

[51] Mey Rude of Autostraddle stated Moondragon would be a "perfect addition" to the Guardians of the Galaxy film series.

[53][54] Moondragon / Heather Douglas appears as a parody character in the Mad episode "Captain America's Got Talent,"[55] voiced by Rachel Ramras.

This version never accessed her full psionic potential and became a member of Quentin Quire's Overmind, a group of low level telepaths tasked with creating a "psychic pyramid scheme" and increasing Quire's limited skills,[57] before the Overmind's members are killed by the Shadow King.

[59] This version, also known as "Heather Moon", is a contract killer who sports a dragon tattoo, possesses considerable martial arts prowess, and was primarily active twenty years prior.

Before she died, she was hired by the Enclave, who created an army of clones from her DNA to help them stop Gah Lak Tus.

[volume & issue needed] An alternate universe variant of Moondragon appears in Marvel Adventures: Fantastic Four #43.

[62] Heather Douglas / Moondragon makes a non-speaking appearance in the X-Men: The Animated Series episode "Beyond Good and Evil (Part 3)".
