Moon Knight (real name Marc Spector, also known as Steven Grant/Mr. Knight and Jake Lockley) is a fictional character appearing in comic books published by Marvel Comics.
Moon Knight is empowered by Khonshu, the Egyptian god of the Moon. This gives him superhuman strength. Besides that, he is an expert at boxing and martial arts and a great combat strategist.
Moon Knight was created by Doug Moench and Don Perlin.
Moon Knight appears as the protagonist in the Disney+ series. He is a vigilante, who suffers from dissociative identity disorder where he learns the secrets of his past. He is under the name of Steven Grant with his real name Marc Spector being hidden. He also has a third personality named Jake Lockley, who is more brutal.
In "The Goldfish Problem", we are introduced to Steven Grant a museum worker who occasionally suffers from blackouts and memories of another life. After going to sleep one night, he wakes up in another country and witnesses a cult meeting led by Arthur Harrow, who demands a scarab Grant unknowingly had in his possession. He escapes and is nearly killed, but is unknowingly saved by a mysterious voice in his head. After waking up in his home and noticing several oddities, Grant realizes that two days have passed since he went to sleep. Upon returning home from a mis-scheduled date, Grant finds a hidden phone and keycard in his apartment. He gets a call from a mysterious woman called Layla, who calls him Marc. The next day at work, Grant is confronted by Harrow, who reveals that he is a servant of the goddess Ammit. Later that night, Harrow summons a jackal monster that attacks Grant at the museum. Just as Grant is cornered by the monster, his reflection in the mirror tells Grant to let him take control. Grant agrees and he transforms into a cloaked warrior who then kills the monster.
Moon Knight was referenced in Doctor Strange, where one of the relics in the New York Sanctum is a white mask with an ankh next to it.
Moon Knight's second personality, Steven Grant, shares the same first name with the original Captain America.
There were reports that Marvel was looking for an authentic Jewish actor for the part with Shia LaBeouf apparently being considered. Oliver Jackson-Cohen was considered and he, along with Ross Marquand, both expressed interest in the part. A leaker claimed that Marvel was looking at Daveed Diggs and Nick Kroll as potential casting choices. Embarrassingly for the leaker, Oscar Isaac was already announced in the part an hour before their post.
