The character, created by Stan Lee and Joe Maneely, is based on the Morgan le Fay of Arthurian legend.

In this version of the character, Morgan le Fay belongs to the species of humanoid magical beings called fairies, who are born with supernatural powers, and is the half-faerie half-sister of the mythic King Arthur.

Morgan le Fay first appeared in Black Knight #1 (May 1955) from Atlas Comics, written by Stan Lee and illustrated by Joe Maneely.

Le Fay agreed on the condition that Doom become the general of her army, undead warriors of those slain by the sword Excalibur against her half-brother King Arthur.

[12] Morgan Le Fay first projected her astral form from her physical body in the Sixth Century A.D. to the present day.

There, she kidnapped the Scarlet Witch and used her reality-warping powers to 'bridge the gap' between her elven magic and an Asgardian doomsday device known as the Twilight Sword.

[22] Doctor Doom is revealed to be in a sexual/romantic relationship with Le Fay, traveling back to the past in order to carry on liaisons with her.

[35] Morgan le Fay possesses a natural affinity for magical forces which is a result of her half-faerie genetic structure.

She possesses a gifted intellect, and as a former pupil of Merlin with centuries of study, she is considered one of the greatest sorceresses in Earth's history.

[45][46] In The New Avengers #53, the Eye of Agamotto appeared to Morgan, as it considered her a possible replacement for Doctor Strange as Sorcerer Supreme.

Doctor Strange cannot simply overpower Morgan Le Fay, but must understand her often-obscured goals in order to do the right thing.

"[5] Gab Hernandez of Screen Rant called Morgan le Fay one of the "smartest magic users", writing, "Morgan Le Fay is one of the oldest magic casters in the Marvel Universe and shown to be one of the most successful at fulfilling her plans time and time again.

She can create physical manifestations of astral clones, manipulate the Earth, shapeshift, and can absorb mystic energy from magical artifacts.

In addition to her Celtic heritage magic, Morgan has studied with the Ancient One and can even use Doctor Strange's signature Crimson Bands of Cyttorak.

"[36] George Marston of Newsarama named Morgan le Fay one of the characters who has the "power, the experience, and/or the pure determination to inherit the Cloak of Levitation and the Eye of Agamotto and take up residence at the Sanctum Sanctorum as Earth's latest and greatest Sorcerer Supreme," saying, "Nearly all of the possible candidates for Sorcerer Supreme - even dastardly Doctor Doom - would ultimately possess the same dedication to the job of protecting Earth from magical threats as Doctor Strange, if not the same methods and morals.

But Morgan le Fay, an evil sorcerer who has been a magical menace to the Marvel Universe since the days of King Arthur, would undoubtedly shirk the job in favor of her own selfish ends.

"[8] Dais Johnston of Inverse called Morgan le Fay "perfect for an Avengers face-off", asserting, "Marvel has explored all sorts of different genres in its 23-movie history, but we haven't visited the story of King Arthur and the Knights of the Roundtable — yet.

A half-fairy with the ability to manipulate mystic energy and a seemingly infinite life span, this super villain been alive since the sixth century and has often found herself depicted as a major opponent for the entire Avengers roster.

"[48] Marc Buxton of Den of Geek wrote, "Let's get all Arthurian with the world's original femme fatale, the wicked Morgan Le Fay.

Le Fay has fought Iron Man many times in her bid to conquer Camelot in the past and present and she has also run afoul of Stephen Strange and is a deadly enemy to all life.

Morgan in the Marvel Universe is, in fact, the same antagonist who troubled King Arthur and Merlin back in the times of the Roundtable, so she has some years under her belt.

Her powers are also staggering as she has the ability to warp reality, travel through time, and use a plethora of magical spells at her disposal.

"[50] An alternate universe variant of Morgan le Fay who conquered half the world following a war between Asgard and Latveria appears in the Age of Ultron storyline.

[55] An alternate universe variant of Morgan le Fay from Earth-13238 appears in "Secret Wars" as the ruler of Weirdworld.

[74] Morgan le Fay appears in Lego Marvel Super Heroes 2, voiced by Kate O'Sullivan.
