Spector has dissociative identity disorder (DID)–which he developed as a result of child abuse at the hands of his mother Wendy, and survivor's guilt following his younger brother Randall's death–with Grant operating as a gift shop employee in London.

Driving a limousine and speaking Spanish, Lockley works with Khonshu in executing Harrow (along with Ammit) after the god removes Spector and Grant from his service.

Mortally wounded, Marc dragged himself to a nearby temple erected in honor of the Egyptian God Khonshu and prepared to commit suicide.

Khonshu himself would intervene, granting Spector a second chance at life in exchange for becoming his avatar on Earth and carrying out his wish to exact vengeance on criminals.

Spector agreed, with Khonshu resuscitating him and bestowing an armored suit and various powers in return, turning him into the vigilante Moon Knight.

[1] Spector survived the cataclysmic events of the Blip incurred by the alien warlord Thanos in early 2018,[2] and had issued a new passport that December.

Out of grief and trauma, Spector allowed Grant to assume general dominance over his body, who continued to remain unaware of his status as an alter to his host.

One night, Grant attempts to keep himself awake, only to accidentally fall into deep slumber and wake up at a village near the Austrian Alps, now possessing an ancient scarab.

He is promptly pursued by enemy forces, retreating deeper into the town where he meets religious zealot Arthur Harrow, who demands the scarab from Grant.

Grant escapes in a cupcake truck while being pursued by Harrow's enforcers; he is unexpectedly saved by a mysterious, disembodied voice communicating to him.

He then heads to a storage facility and uses the key that he found in his flat where he discovers Spector's belongings, including the scarab he escaped with hidden inside a duffel bag.

The two of them go to Grant's flat where he is apprehended for stealing the scarab by Police Constables Billy and Bobbi, who are secretly followers of Ammit serving as Harrow's disciples.

The jackal successfully overpowers Grant, tiring him physically, and causing him to reluctantly converse with and relinquish control to Spector, who dons the Moon Knight armor and kills the beast.

After losing one of Ammit's worshippers to suicide, Khonshu causes a solar eclipse, intended to call for a council hearing of the Ennead and their respective avatars.

[1] In the first reality, Grant identifies the woman as goddess Taweret, who explains they are dead and the "psychiatric hospital" is a boat sailing through the Duat, the Egyptian afterlife.

Grant discovers Randall's death and Wendy's abusive actions, while Spector shows him a memory of how he became Moon Knight and Khonshu's avatar on a mission with Bushman.

The scales fail to balance, causing hostile spirits to attack the boat and push Grant overboard, freezing him into sand.

As Harrow, Ammit, and their followers begin judging everyone in Cairo, Spector, Grant, Layla as Scarlet Scarab, and Khonshu arrive to engage them in battle.

The pair find themselves in "Dr. Harrow"'s office, where they reject the vision and choose to continue their new life together and wake up in Grant's apartment in London.

During the battle of New York, he fought alongside Shang-Chi, Monica Rambeau, Bucky Barnes, Nakia, and the Red Guardian using the Mighty Avenger Protocol.

Editors Marv Wolfman and Len Wein liked the character and decided to give him a solo story in Marvel Spotlight #28–29 (June/August 1976),[9] again written by Doug Moench with art by Don Perlin.

[10] Moon Knight acted as a hero again in Marvel Two-in-One #52, written by Steven Grant with art by Jim Craig.

Magazine issues #13–15, 17–18, and #20, creating a new look for the character heavily influenced by the art of Neal Adams, who at that time was most popular for his work on Batman and Green Lantern/Green Arrow for DC Comics.

[13][14] The Hollywood Reporter commentator Richard Newby spoke on Isaac's potential in the role, remarking that Isaac's recent major acting roles could draw audiences unfamiliar with the character to the series, and that his Latino ethnicity could allow an examination of faith from different perspectives, rather than having the character be depicted as a "Caucasian Jewish man" like in the comics.

[16] Moon Knight's costume consists of armor and Ancient Egyptian bandages, with hieroglyphic-like symbols on his cape,[20][21][19]: 12  which feature Khonshu's oath and are in a repeating pattern on the underlining in a foil-like fabric.

[17] The moon crest on his chest, from which he spawns his crescent darts, also contains the oath of Khonshu, while additional hieroglyphs on his pants that state "Rise and live again as my fist of vengeance.

[17] As a child, Marc Spector developed dissociative identity disorder as a result of his mother's physical abuse when his brother accidentally drowned.

[28] Steven Grant is introduced as a shy person, letting people push him around, working in a museum gift shop, and having good Egyptian mythology knowledge.

He is shown to have the most violent tendencies out of any of Marc's alters, as seen when he escorts the rehabilitated Arthur Harrow to his limousine, before proceeding to gleefully execute him, pleasing Khonshu.

[30] Speaking on the decision to fully introduce Lockley at the end of the season, head writer Jeremy Slater remarked he was aware that people familiar with the Moon Knight canon were dedicated to finding the various allusions made to his presence throughout the prior episodes, instead focusing on "everyone else who's totally unfamiliar with the character and the dynamic", while ensuring that the final reveal of the character would work as "satisfying for the newcomers to the Moon Knight story".
