The Skrulls, a race of extraterrestrial shapeshifters from Marvel Comics and the MCU, have become a staple in meme culture due to their ability to impersonate anyone. The Skrull meme typically highlights feelings of paranoia or betrayal, often used when a friend, celebrity, or public figure acts significantly out of character. Since the release of the Captain Marvel film and the Secret Invasion series, the template has evolved to feature the iconic green-skinned aliens or dramatic 'reveal' moments. It serves as a humorous way to suggest that someone is an imposter or a plant, tapping into the classic 'Trust No One' trope that has dominated internet humor for years.
