Warning! Spoilers ahead for Moon Knight Annual #1While Moon Knight knows the sway that gods and prophecies can hold over people in the Marvel Universe, he also understands these things have less power than people think. Marvel's world is one where gods and magic, heavens and hells, are not just ancient myth and superstition but very real, tangible things. One of the founding Avengers, Thor, is himself a literal god hailing from the heavens of Old Norse myth. No mortal knows these truths better than Moon Knight aka Marc Spector, whose entire superhero career and identity he owes to his connection to the Egyptian god of the moon, Khonshu.
Marc Spector was once a mercenary, left for dead in the sands of Egypt as payment for his crisis of conscious. Bleeding out under a statue of Khonshu and illuminated by the moon that the god represents, Spector agreed to serve Khonshu in exchange for his life. It was a willing transaction, and Marc Spector has served as Khonshu's avatar and fist in the god's eternal mission ever since. Khonshu's grasp over Spector, however, is only a thing of compulsion: Moon Knight's will remains his own.
The nature of this relationship and the gods of Marvel's world is put on full display in 2022's Moon Knight Annual #1 by Jed MacKay and Federic Sabbatini. Moon Knight's daughter Diatrice has been kidnaped by Werewolf by Night Jack Russell. Russell has discovered a prophecy upon reading from the eldritch tome the Darkhold and maintaining his sanity. Under a planetary alignment, the "King of Wolves" can turn the child of Khonshu's Fist (aka Moon Knight) into one of his own and create a weapon capable of killing the moon god. Diatrice, by all means, shouldn't exist: serving as Khonshu's avatar brings with it sterility, making the young girl the first and only one of her kind. Jack Russell is, by his own decree, the King of the Wolves, a title he earned by defeating the leaders of all other werewolf packs and waging war against Wendigos. Khonshu himself recognizes the threat Russell poses, and is looking to avert his own demise by any means necessary. This includes ordering his other fist, Hunter's Moon, to kill Diatrice so that Russell can't fulfill the prophecy.
Moon Knight Proves Prophecies Can Simply Be Ignored
This isn't Jack Russell's first brush with gods and prophecy. In 2011's X-Factor #224 by Peter David and Emanuela Lupacchino, he becomes the adoptive father of Tier Sinclair, a lycanthropic child born of both mutant and god. Tier is foretold to play an important role in a war to come that will bring about the apocalypse. Tier is hunted relentlessly by those who fear the prophecy, and his young life is taken before Mephisto and the other lords of Hell can start the prophesied war.
Neither prophecy comes to pass. Tier is struck down in the battle to force his role in the apocalypse while Jack Russell, Moon Knight, and Hunter's Moon all choose to ignore the prophecy and let its singular opportunity fade. These events aren't set in stone, only predictions of what could be should someone choose to act. While Diatrice's existence is aberrant, Russell's efforts to see himself crowned "King of the Wolves" is a conscious decision on his part. Khonshu's efforts to have Diatrice killed to prevent the prophecy fall equally flat: both of his fists, Moon Knight and Hunter's Moon, simply ignore his orders. Khonshu may be a god and Marc Spector his avatar, but he's unable to command Spector as he can the moon. During the brief Age of Khonshu, Spector eventually turns on his patron, having only served him while he agreed with the god's mission. Gods like Khonshu may wield incredible power, but their machinations often rely on mortals to be willing to obey their commands.
Had Khonshu, Diatrice, or Moon Knight died it would have been by someone's deliberate hand: not inescapable destiny. In a world where gods literally walk among mortals, free will remains a more ironclad force than prognostications in ancient texts. Moon Knight proves that the only power gods and prophecies have over others is the power people choose to give them.
