Xenomorph (Latin, Internecivus raptus, meaning "Murderous Thief") are endoparasitoid extraterrestrial species with multiple life cycle from the planet Proteus or also called Xenomorph Prime. One of the most deadly of all known alien species, these creatures need a host organism in order to reproduce and will kill any non-xenomorph life form on sight regardless of age or species. The appearance of the xenomorph varies depending on its parent host. The human phenotype is generally around 7-8 feet, and roughly 136.0 to 181.4 kg with a long muscular tail and large oblong head. The Queen of the species is generally twice as large, weighing ten times as much, having much greater speed, strength, and intelligence. The term Xenomorph is derived from the greek words xeno ("stranger", "alien", and "foreigner") and morphe ("form", "shape").
