WARNING: The following contains major spoilers for Moon Knight #6, available now from Marvel.
Ever since he returned to the streets under the auspices of his new Midnight Mission, Marc Spector has been set upon by all manner of night-bound foes. This has included a couple who hit a lot closer to home than he is used to. The enigmatic Zodiac has made the Moon Knight's life a living hell so far, but it is the other Fist of Khonshu that Marc's life has been most upset by. Thankfully, the Hunter's Moon isn't just a dark reflection of Marc's return, nor is he the villain that his initial appearance would imply. In fact, Marc Spector's latest rival isn't that great of a threat at all, despite loathing everything the Midnight Mission stands for.
Apart from all of the good work he had been doing through the Midnight Mission, Marc Spector hadn't been able to shake the unrelenting villains who had plagued him, especially the maniacal Zodiac. As the Midnight Mission burned to the ground, Moon Knight could only watch as Zodiac prepared to continue his killing spree. During this, Reese ran to the Hunter's Moon for help putting an end to the fight. Not only did he save Marc's life, but he had also made it clear just where the two of them stand, and it's closer than anyone could have possibly guessed.
As Doctor Badr aka The Hunter's Moon revealed in the pages of Moon Knight #6 (by Jed MacKay, Alessandro Cappuccio, Rachelle Rosenberg, and VC's Cory Petit), any hate or lack of respect he might feel for the titular hero is vastly overshadowed by their respective places at the hands of Khonshu. This, at least in Badr's mind, made them brothers of sorts, and it was that relationship that caused the Hunter's Moon to question everything he has come to believe. As he was tending to Marc's wounds, Badr explained that his upbringing in a well-to-do and strictly religious family left him determined in his aspirations yet disillusioned in his faith. It was only after being left for dead by a roving pack of vampires that Badr was called upon to serve his patron god and given the gift of life as the Hunter's Moon. That experience was what gave him such a zealous dedication to Khonshu, which in turn led him to hold such great disdain for Marc Spector. Although from what he had seen recently that may all be turning around sooner than later.
Badr's upbringing and origin couldn't be farther from Marc Spector's own. Even if they both had similarly religious families and violent introductions to Khonshu, they had also gone through vastly different journeys to arrive at the same place. Along the way, Marc Spector had found good reasons to take up the Midnight Mission and provide a bright, moonlit path for those who travel at night to take without worry. Badr, on the other hand, had staunchly opposed that same sort of mercy in favor of a more traditional brand of service. Seeing that Moon Knight had embraced a vampire as a confidant and partner had seemed like a slap to the face of Khonshu's teachings. But, the fact that Reese risked her own life to call on the Hunter's Moon to save Marc's life had cast a doubtful shadow on everything he thought he knew.
While Badr's actions as the Hunter's Moon are understandable considering the life he lived and lost before meeting Khonshu, they are also a series of reactionary choices based on little more than his own preconceived notions. From the looks of things now, Badr could very well be on his way towards a new outlook, although there is no telling what the fallout of that would be. Khonshu has never taken kindly to his champions going their own way, and the ancient deity certainly isn't done with either of them yet. Of course, if one Fist of Khonshu alone was powerful enough to walk away from the god's influence, both of them would likely have no problem carrying out whatever mission they decide on for themselves.
