Genestealers

A Genestealer (Corporaptor hominis) is a bioform of the multispecies Tyranid race that was genetically designed by the Hive Mind for the infiltration of other intelligent species’ settled worlds. The Tyranids are a nomadic xenos species governed by a gestalt collective consciousness known as the Hive Mind. The species comprises many different genetically-engineered bioforms, of which the Genestealer is but one. Genestealers are capable of using their unique, parasitic reproductive cycle and psychic abilities to establish so-called “Genestealer Cults” on Imperial worlds. These cults are used to support hive fleet assaults by infiltrating the Human world’s society and military defences from within.
