1) Moon Knight
Considering the fact that Moon Knight is one of their most interesting and psychologically complex characters, it’s honestly surprising that Marvel didn’t decide to make him part of The Defenders when they first struck that deal with Netflix.
After being resurrected by an ancient Egyptian God, Marc Spector embarked on a career as a superhero, but suffers from a split personality disorder and some serious delusions. That makes him pretty dangerous, something which was evident a few years back when he ended up carving off the face of one of his greatest foes.
Exploring that side of him and just the fact that this is a great character should make Moon Knight a priority for Neflix, and like Daredevil, he’s someone who would benefit from a run of episodes over a single movie.
