The UFO, also known as Jean Jacket, (Scientific name: Occulonimbus edoequus) is the main antagonist of the 2022 science fiction western horror film Nope. Unlike traditional depictions of a spacecraft piloted by extraterrestrial beings, it is a massive airborne creature adorned with tough, scale-like plating.
In its natural form, the alien resembles a large jellyfish with a square-shaped singular eye that is safeguarded by hundreds of protective green ribbon-like eyelashes. These lashes sway and undulate in a pattern that lures in unsuspecting wildlife and humans to gaze at Jean Jacket. Instead of employing conventional predatory methods like biting, the UFO's mouth extends to engulf its ensnared prey whole, then employs its arms to transform into a conventional UFO.
