4) Moon Knight

Speaking of, despite only appearing in a Disney+ series, Moon Knight is one of Marvel’s most popular second-tier superheroes, which is surely one of the reasons Oscar Isaac was brought in to portray Marc Spector/Steven Grant on the show. Besides, not only has there been discussion that the TV series might eventually get a second season, but Moon Knight has also been a member of multiple Avengers teams in the comics. That would seem like the character’s future is locked up… but if there’s no season two, movie appearances seem even less likely to happen. Plus, the super-popular actor’s work schedule is packed with future projects, including the Metal Gear Solid movie. Would Marvel let Moon Knight languish? And what about Layla El-Faouly (May Calamawy), aka the Scarlet Scarab, while we’re at it?
