The Skrulls are a fictional race of extraterrestrial shapeshifters that appear in American comic books published by Marvel Comics. They first appeared in Fantastic Four #2 and were created by Stan Lee and Jack Kirby. The Skrulls originated from the planet Skrullos, and their empire is located in the Andromeda Galaxy. Their bodies are permeated with unstable molecules, granting them shape-changing abilities, and they can take any succession of forms and resume their true shapes via mental concentration. Most Skrulls are unable to take shapes more than 1.5 times their original volume or less than 75% of it, but a handful have mastered their potential sufficiently to change to near-microscopic or gigantic sizes. The Skrulls have made numerous appearances in animated television and video games before making their live-action cinematic debut in the Marvel Cinematic Universe film Captain Marvel (2019) . They have also appeared in Spider-Man: Far From Home (2019) and the Disney+ series WandaVision, What If...? (both 2021), and Secret Invasion (2023) .
