31Honorable Mention: Skrulls
Ever since fans heard the rumor that Skrulls would appear in Captain Marvel, the alien species loomed over the future of the Marvel Cinematic Universe. They will make their MCU debut in Captain Marvel’s movie, but we don’t know how close
they will be to their comic book counterparts.
The Skrulls were part of one of the biggest Marvel events: Secret Invasion. As a race of shapeshifters, they had the technology to replace a Skrull’s memories and abilities with those of the person they became. Many heroes were captured and replaced by the Skrulls over years in the comics. We’ll see if the same turns out to be true for the movies.
