Description: A perfect organism designed to kill, the Xenomorph emerged from the chest cavity of a host and sought cover in the shadows of the Nostromo. Using the air ducts, it killed its prey one by one, until only the human Ripley remained. Desperate for survival, Ripley destroyed the Nostromo and sought refuge in an escape vessel. As the Xenomorph went in for the kill, the airlock opened and it was ejected into the cold vacuum of space. All seemed lost, until in an instant, it disappeared in a cloud of black fog.
