WARNING: The following contains major spoilers for Devil's Reign: Moon Knight #1, available now from Marvel.
Wilson Fisk's crusade against the heroes of New York City has seen some of Marvel's finest locked up behind bars alongside its more minor villains. Among those caught in Fisk's clutches is none other than Marc Spector. Despite being surrounded by both former and current allies, Marc has largely had to suffer his stint in prison alone. As it turns out, he isn't particularly welcome in the presence of his superpowered colleagues until some greater threat forces them to work together. It may seem cruel, but even Moon Knight knows there is good reason for his allies to keep their distance unless they absolutely need him.
Things inside the Myrmidon haven't been going particularly well for Marc Spector. After ending up inside this supermax prison for superpowered criminals, Marc has found himself ostracized by seemingly everyone except for D-list villain Jeff Hagees, aka 8-Ball. As seen in the pages of Devil's Reign: Moon Knight #1 (by Jed MacKay, Federico Sabbatini, Lee Loughridge, and VC's Cory Petit), not even Moon Knight's fellow incarcerated heroes seem to want to have anything to do with him. This isn't to say that they respect him any less than their other occasional teammates, but rather that they understand the danger Marc poses simply by being. At the same time, that hasn't stopped Marc's allies from keeping him as close as is safe for everyone involved, especially when he means so much to them even at his worst.
While Moon Knight has been one of the more brutal heroes in the Marvel Universe ever since his first introduction back in 1975's Werewolf by Night #32 by Doug Moench and Don Perlin, that same fervor has also made him one of the most effective in his line of work. That trait hasn't helped much when it comes to his personal relationships with other vigilantes, leaving him with few genuine superhero friendships. Still, he has made efforts to meet others halfway. This is best exemplified by Marc's willingness to open up to an Avengers mandated therapist following him singlehandedly saving the world from Khonshu's rule.
Defying his patron god was a powerful indicator of the profound personal changes that Marc has been making, and his Midnight Mission is just another sign that he has become truly determined to make a better life for himself and those around him. No matter how noble that might be, it isn't the reason why Moon Knight believes other heroes continue to tolerate his presence. As far as he can tell, it is his raw power and willingness to unleash torrents of pain upon his enemies that makes him more of an asset than a liability in the eyes of teams such as The Avengers. Earth's Mightiest Heroes have seen firsthand on multiple occasions the impossible extent to which Marc can push himself. That may be terrifying on the surface, but up against a force like the one Wilson Fisk has built, it is also the best shot the world has at being saved.
There isn't any doubt that Moon Knight and the other heroes imprisoned in the Myrmidon will be making their escape sooner than later, nor that they will be able to turn the tide of battle against Fisk and his Thunderbolts. At this point, the biggest concern is how much damage will be done in the process. Hopefully, whatever measures Moon Knight takes in dismantling Fisk's reign won't be more than he can personally recover from. If so, he may not be on the same side of the fight by the time the dust has settled.
