Xenomorph (Earth-9471)

The "xenomorphs", designated as LF.Xx.3273 by the forerunners (Latin Linguafoeda acheronsis meaning "foul tongue from Acheron"), are a highly aggressive sapient endoparasitoid species that can quickly reproduce and grow through the infection or impregnation of other species with sufficient cognitive capabilities. With origins shrouded in mystery and uncertainty, xenomorphs reproduce by spreading its infection towards other organisms, hijacking their bodies and impregnating them with a Chestburster, which in turns is converted into one of the species' many specialized forms. By impregnating other species, xenomorphs become increasingly more intelligent, and because of their frighteningly rapid growth rate, they are effectively unstoppable.

All xenomorphs share one single consciousness, which increases with each host it impregnates, eventually forming the ultimate xenomorph shared mind known as a Queen: a self-aware and incredibly intelligent entity which commands all other xenomorphs during outbreaks. Because of their group-like consciousness, the xenomorphs are better described as a single, trans-sapient macro-organism instead of individuals. When a Queen is not present, xenomorphs are only basically coordinated through the Feral Stage, where they seek to build more and more biomass through hives, leading to the creation of Proto-Queen and Queens in the Coordinated Stage. Xenomorph collective consciousness can only be described by humans as likening to a socialistic utopia, with each component of the species working to ensure their survival.
