Moon Knight is a superhero appearing in American comic books published by Marvel Comics. Created by writer Doug Moench and artist Don Perlin, the character first appeared in Werewolf by Night #32 (August 1975).
The son of a rabbi, Marc Spector served as a Force Recon Marine and briefly as a CIA operative before becoming a mercenary alongside his friend Jean-Paul "Frenchie" DuChamp. He is killed by Raoul Bushman, but the god Khonshu resurrects him as his avatar. After returning to the United States, Spector becomes the crimefighter Moon Knight, aided by Frenchie and Marlene Alraune, who becomes his lover. Along with his costumed alter ego, he uses three other identities to gain information: billionaire businessman Steven Grant, taxicab driver Jake Lockley, and suited detective and police consultant Mr. Knight. It is later revealed Moon Knight has dissociative identity disorder and that the Grant and Lockley alters emerged during his childhood.
In most depictions, Moon Knight has no abilities beyond his athleticism and detective skills. For a time, he had superhuman strength and durability derived from the phases of the moon, but this ability later vanished.
The character has made appearances in various media outside of comics, including animated series and video games. Oscar Isaac portrays the character in the Marvel Cinematic Universe series Moon Knight.
