Maître d'Essaim Genestealer

Genestealers are terrifying close combat horrors with the individual strength and speed to tear apart even an armoured Space Marine if they can get close enough to land a telling blow. They stand almost six feet in height, even hunched over as they are on hind legs, their four arms ending in claws, talons or other bio-weapons capable of cutting through ceramite and plasteel with equal ease. Cunning and independent, Genestealers are also one of the few Tyranid creatures which can exist away from the nurturing and controlling influence of the Hive Mind, using their own innate intelligence and brood telepathy to form tight-knit groups. These groups can survive for decades or even centuries on worlds, hiding their presence and infecting more and more of the population until the time to strike arrives, usually coinciding with the arrival of the hive fleet and the wholesale invasion and consumption of the world itself. Few Tyranid creatures have earned such a terrible reputation or caused as much damage to the Imperium as the Genestealer. Detected long before the first tendrils of the hive fleets reached the galaxy, they were thought to be little more than another unusual and deadly alien xeno-form. It was only after the horrors of Behemoth and Leviathan that the Imperium came to realise their true purpose as advanced scouts for the Hive Mind and infiltrators of the most insidious kind. Hiding away on void ships and in the depths of space hulks, the Genestealer menace has travelled across the length and breadth of the Imperium of Man, seeding themselves onto worlds and subverting their populations. This perhaps is the greatest horror the Genestealers bring, as they can infect almost any life form with a “kiss,” implanting some of their own genetic material into the host and taking complete control of it. When the host gives birth to offspring, these carry with them the Genestealer’s genes and over a few generations a new Genestealer is born, albeit with some genetic traits taken from its host—such as the human-like hands many Genestealers encountered in the Imperium possess. Purestrain Genestealers are Genestealers which have been spawned not through the process of infecting hosts but rather by the hive ships themselves in great bio-factories and birthing vats. Not polluted or altered by “inferior” genetic material, they are markedly stronger and faster than a normal Genestealer and possess a wider variety of adaptive biomorphs. This is intentional, as Purestrain Genestealers are the creatures from which all other Genestealers are born, and even a single Purestrain Genestealer can create a vast brood from a local population given time and enough raw material.
