WARNING: The following article contains major spoilers for Nope.The alien villain Jean Jacket in Nope‘s ending morphed into a jellyfish-like creature after taking on the appearance of a classic UFO design for most of the film. While this made for an impressive visual spectacle, it left many wondering what the alien in Nope actually was. The Nope alien’s physiology was unique and defied many people’s expectations of what sci-fi horror extraterrestrials look like (although this was to be expected from Jordan Peele, a director known for subverting tropes). Jean Jacket was an enigma, especially when it changed forms. Nope left many mysteries unanswered, but hints dropped throughout the movie may explain the creature’s behavior — although the less-than-definitive answer still leaves much mystique around the Nope alien.
