The series, which is a semi-sequel to Captain Marvel, features the return of Samuel L. Jackson as Nick Fury and Ben Mendelsohn as Talos, leader of the alien Skrulls. In the comic book story of the same name, the shapeshifting Skrulls conduct a clandestine invasion of Earth which is stopped by the Avengers. However, the Skrulls in the Marvel Cinematic Universe are more sympathetic and presented as potential allies of the human race. It's more likely that the MCU version of the story will feature either civil war within the Skrulls (as some wish to take over Earth and others work alongside humans) or possibly a struggle between Skrulls and their traditional enemies, the Kree.
