Goose the Cat first appeared in the 2019 film Captain Marvel as the loyal companion of Carol Danvers and Nick Fury. While appearing to be an ordinary ginger tabby, Goose is actually a Flerken—a dangerous alien species with pocket dimensions inside its body and giant tentacles that emerge from its mouth. The meme gained popularity among Marvel fans who loved the contrast between the cat's adorable appearance and its chaotic, terrifying power. It is frequently used to represent things that look harmless but are actually dangerous, or to joke about how Nick Fury lost his eye in the MCU.
