It’s unclear whether or not Marvel Studios' Moon Knight was well-received or not. The show had some issues, and they were noticeable. However, Oscar Isaac (Marc Spector and all his personalities), Ethan Hawke (Arthur Harrow), F. Murray Abraham (Khonshu), and May Calamawy's (Layla El-Faouly) amazing performances can’t be denied. The initial response was positive, but fans have since pointed out issues with it in the years since its debut on Disney Plus.
However, it sounds like there some ideas planned for the show that never came to fruition in the finished product - that includes a certain Moon Knight villain who was pitched, but sadly didn't make the cut thanks to their similarity to Black Panther's Erik Killmonger. And, if this writer is being honest, it could have changed the trajectory of the show and its characters.
During a conversation with ComicBook.com, the creator of Marvel Studios’ Moon Knight, Jeremy Slater, was asked if there was a specific story he wanted to tell in the series. In a shocking revelation, he said “... we really tried to make Bushman work as the principal antagonist for the first couple of drafts," adding:
“The goal was if Marc Spector was the Avatar of Khonshu, we were going to take Bushman and make him the avatar of a different Egyptian god and let them duke it out.”
Slater described how skilled Bushman is with weapons and how formidable he would be due to his tactile military-training, but pointed out that all of this also describes Erik Killmonger.
Before Raoul Bushman became Moon Knight’s deadliest enemy in Marvel Comics, he was Marc Spector’s right-hand man. That changed when Bushman murdered someone close to him, Dr. Peter Alraune, attempted to kill a woman he loved (Marlene), and beat Marc close to death. As the Moon Knight lore goes, this event leads to Marc finding the tomb of Khonshu and then becoming the Moon God’s avatar. After that, the two ended up in multiple blood-filled battles. In the end, Moon Knight was too much for Raoul Bushman.
During the first of their final encounters, Marc carves Bushman’s face off with one of his crescent moon projectiles (Moon Knight: The Bottom, written by Charlie Huston with art by David Finch). Bushman is later resurrected by The Hood and driven crazy during Vengeance of the Moon Knight: Shock and Awe (written by Gregg Hurwitz with art by Jerome Opena and Leinil Francis Yu).
The one problem with bringing in Raoul Bushman into the MCU show is how it would have fit within the story. Arthur Harrow worked as the Disney Plus show's villain because that explained who the Egyptian Gods were and how Marc received his powers. Adding Bushman to this series may have taken away from Arthur's storyline. And, if Bushman was used as just a henchman, that takes away from him being one of Marc’s most dangerous enemies. The character needs a backstory and to be more than just another goon.
Slater says he hasn’t spoken to anyone from Marvel in years and is unsure about whether the show will get a second season - and that, if it does return, he likely won't be involved in it, That being said, the series could continue with a new showrunner at the helm, and Bushman could be used. Marvel Studios' Head of Streaming, Television, and Animation Brad Winderbaum recently implied that Moon Knight season 2 likely won't happen for the foreseeable as the franchise has other plans for the character, with speculation already beginning that the long-awaited Midnight Sons movie could be back on the horizon.
