By the time a Genestealer Cult launches its insurrection, its Neophyte Hybrids make up a horde of thousands. Weathered and toughened by a life of hard labour, each cultist features the inhuman reactions and strength their alien genes gift them. These third and fourth generation hybrids can pass as human – sinisterly, some can even infiltrate the Astra Militarum, such are their blessings. When the cult signals their attack, Neophytes swarm from sewers, catacombs and shadowy barracks, overwhelming their enemies and seizing control of entire planets within hours.
