The Empress is a larger version of the Xenomorph Queen, also capable of laying eggs which produce Queen Facehuggers, which in turn birth Xenomorph Queens. It is supposed to be the original queen of a particular area, and mother to all the Xenomorphs on the planet. The Empress is the 2nd smartest of the xenomorphs, coming after the Queen Mother. The Empress is also incredibly large, standing at 20 feet (approximate guess). Like the Queen Mother, the Empress also has incredible telepathic powers, though not as strong. Should the Empress come under attack and die, the Queen Mother will send another Empress to aid the Xenomorphs still on the planet.
