The Nostromo Drone, or also simply known as "The Alien", is the titular main antagonist of the 1979 sci-fi horror film Alien, and the overarching antagonist in its 2024 sequel Alien: Romulus. The creature comes to be after Kane, a member of the Nostromo space station crew, is infected by an alien facehugger and impregnated by it. This leads to the horrifying birth of the alien Drone, which begins to hunt the remaining members of the crew attempting to turn the Nostromo into its own Xenomorph nest. Eventually, the creature is pitted against the last remaining crew member and Alien series protagonist Ellen Ripley in a fateful game of cat and mouse. It is a deceased sibling of the Sevastopol Drone.
