The Dominatrix (plural: Dominatrices, species name: Tyranicus praepotens [Needs Citation]) is a Tyranid species which exerts a controlling psychic aura to bring lesser Tyranid creatures under its will, allowing the swarm under its command to operate with uncanny efficiency and tactical ability. However, a Dominatrix is extremely rare and only seen in the most advanced Tyranid swarms.
A Dominatrix possess a large array of Bio-weaponry and packs a colossal mass, dwarfing that of an Imperial Super Heavy Tank. It has an intelligence akin to that of a mighty Hive Tyrant, and the link it has to the Tyranid Hive Mind surpasses even the Hive Tyrant's.
A Dominatrix is a gargantuan composite creature of nightmarish proportions, equipped with ripping claws and fangs, and a stunning profusion of symbiotic weaponry. Dominatrices are the brood queens of the Tyranid hordes, their children spawning into all the different Tyranid classes. Inside her are all the gene sequences of the galaxy's most lethal creatures, ready to be spliced and twisted by the Hive Mind.[Needs Citation]
Because of the importance of a Dominatrix, which is also the most powerful link to the Hive Mind a horde has, they are strategic targets of the highest priority. Destroying a Dominatrix can decide whether a planet falls to the Great Devourer, or is saved.[Needs Citation]
