Marvel Studios is ramping up the lead-in to its big, all-in, Multiversal throwdown movie Avengers: Secret Wars with The Fantastic Four: First Steps opening the door this summer, and Avengers: Doomsday setting the stage in 2026 before Secret Wars finally arrives in 2027.
But even with Doomsday already sporting a massive cast that spans different worlds, there are still important characters from both the 1985 and 2015 comic book versions of Secret Wars, which will both be hugely influential to the Secret Wars movie, who still haven't made their MCU debut.
