Dawn of War Codex

FunkyMonkey wrote:The black and white chart showing the different generations suggests it goes from pure genestealer to less genestealer to magos

First generation: The first generation Hybrids are born to human (or otherwise) parents, one of which has been infected. Of all the generations they resemble Genestealers most closely. They have either three or four arms.

Second generation: Second generation hybrids always possess three arms, one of which ends in the genestealer claw.

Third Generation: These hybrids possess bodies somewhere between the crouched bodies of genestealers and the humanoid shapes of humans. They appear perpetually crouched, possess two or three arms one of which might end in a genestealer claw. Some lack the ovipositor of preceding generations; these are called drones or neuters, although they can still infect other races through their blood.

Fourth Generation: This generation is virtually indistinguishable from members of the host species. They retain the hypnotic gaze of genestealers, making them rather charismatic. A "mutant" which can appear among this generation is the Magus, which takes the highest position in a Genestealer Cult, besides the Genestealer Patriarch. The first offspring of fourth generation hybrids are invariably purestrain genestealers, allowing the cycle to continue.
