But now that Disney officially has access to Marvel's mutants, one has to wonder if/when they could eventually join the Marvel Cinematic Universe. It feels like a great time to get a new cast of characters, as many of the OG heroes are coming to the end of their contracts with Avengers: Endgame. As such, Marvel Studios is presumably going to need to put more stock in newer characters like Black Panther, Spider-Man, and Doctor Strange. And adding in the X-Men might be a great way to keep the MCU filled out, and ripe for more epic crossover events.
