SPOILER WARNING: The following article major contains spoilers for Captain Marvel, now in theaters nationwide.
The Skrulls that appear in Captain Marvel were somewhat surprising. Instead of being the traditional threat they are in the comics, the ones introduced in the Marvel Cinematic Universe are desperate refugees trying to find a new home for their families. It's a more sympathetic portrayal of the alien race than usual, but Marvel Studios President Kevin Feige is hinting that the shape-shifting species may not always be allies to humanity.
During an interview with /Film, Feige teased the possibility of an eventual adaptation of the Secret Invasion event. When asked if their general friendliness meant the Skrulls wouldn't target Earth in the future, Feige explained, “I don’t think it means that at all. I think it means that the Skrulls are as diverse and a multilayered as any other intelligent life form. Certainly like humanity itself. And we happen to see good ones. I think there are probably better ones out there as well, like there are with any fully realized characters."
While it's not a full-blown confirmation, it does hint that we could see an eventual darker side of the species, which could easily set up an adaptation of Secret Invasion, the 2008 Marvel Comics event that revealed that the Skrulls had successfully infiltrated the Earth in preparation for a major invasion of the planet. Even replicating members of the superhero community, the event forced the then-splintered Avengers back together to unite against the Skrulls. The event ended with the Earth saved, but the world lost confidence in the heroes, which set up the events of Dark Reign.
