Moon Knight
The MCU has introduced all of the core Avengers at this point, but there are still plenty of ancillary members that could be introduced in future phases.
By far one of the most interesting Avengers not currently in the MCU is Moon Knight, a character who’s been a member of the Avengers, Secret Avengers, West Coast Avengers, Defenders, and more.
Moon Knight, or Marc Spector as his alter ego is known, was first introduced in the 70s as a villain for Werewolf By Night. The character showed popularity and was later reintroduced as a hero, over the years becoming a staple member of the aforementioned superhero teams.
Moon Knight has the chance to be an incredibly unique movie in the MCU, a kind of detective-thriller mixed with plenty of trademark superhero action. Moon Knight is an ace detective, oftentimes using his skills of deduction to help the Defenders figure out mysterious of villainous schemes.
On top of that, he’s an expert martial artist, and the character gains increased strength and abilities based on the cycle of the moon, hence the name.
If Marvel is looking to introduce any new Avengers in Phase 4, Moon Knight should be on the top of that list. In fact, one of the Avengers: Endgame screenwriters, Christopher Markus, recently said that Moon Knight is one character he’d be interested in bringing to the big screen.
