Genestealers are a species of the tyranids that specialize in infiltration and are the ultimate shock trooper for their hivemind's disposal. These species of aliens are known to inhabit human settlements and dark places.
The genestealers landed on our planet and created a cult so as to help make things easier for their hive fleet to come and invade our world by infiltrating governments and military positions during the time of the previous demon lord. Unfortunately when the new demon lord arose the demonic energy turned both the genestealers and the hive fleet's bioforms into sexy monster girls with an insatiable hunger for men's spirit energy.
Just like all the other tyranid bioforms genestealers desire a human male as a husband but will go after one that fancies them. They would rationally and calmly try to get him to become her husband through any means. Although while having sex all rational thoughts are thrown out of the window and replaced with their bestial instincts during intimate moments with their husband.
Genestealers are capable of forming genestealer cults on different planets. These cults are led by a genestealer patriarch, which is a genestealer twice the size of a normal one and being both physically stronger and having psychic powers on their side. The genestealer cult in our world is known to all of the mamanos and are actually accepting of both monster girls and humans who want to join their group. The patriarch of this cult broadcasts information to the hive fleet on any events happening in our world such as the fall of Lescatie.
Genestealers have sharp claws that can tear through even the toughest materials like butter. They possess rather cunning and intelligence able to think on their own outside of the hive mind and even when cut off. They are also able to survive wounds that would normally kill off any normal human and can easily overpower one in combat.
Genestealers have four arms with the upper ones having three sharp claws and the lower ones being regular arms. Their physical looks resemble that of their original forms pre-exposed but have features of human females such as their bosom and skin. The genestealers' skin, chitin, and hair depend entirely on what hive fleet they are affiliated to but their eye color is yellow. Since the genestealers of our world are affiliated with Hive Fleet Leviathan they have dark purple chitin, white skin, and purple hair.
A/n: I am definitely going to be killed by that lady from If The Emperor had a text to speech device who hates genestealers. And the one who ruined Kairos' face. I hope you enjoy a 40k entry into this list because there's going to be more coming.
