The Xenomorph XX121, better known just as Xenomorph (which literally translates to “strange form” from Greek ξενος, xenos=strange and morphe=form) or the “Alien”, is an extraterrestrial endoparasitoid species with multiple life cycles, possibly originating from the planet Proteus (also known as Xenomorph Prime). One of the deadliest of all known alien species, these creatures require a host organism in order to reproduce.
