Genestealer

Genestealers are a sub-species of Tyranid tasked with infiltrating the communities of other species and preparing them for Tyranid invasion. To achieve this goal, Genestealers will seek out and infect victims with Tyranid genetic material, bending their will to the hive mind and compelling them to reproduce. Succesful procreation of these infected victims will invariably result in the birth of a hybrid of Tyranid and the species of the infected host.
