Overview
The hydralisk is a Evolution of the slothien in the cosmos, combined with seven or eight distinct and diverse organism strains. While slothiens were peaceful herbivores, the hydralisk is noted as being one of the most fierce and sadistic of the Great Swarm strains, though not as the Genestealer or the Tyranid Warrior. Hydralisks are a versatile combat strain, and form the backbone of the Great Swarm, acting as shock troops. To Gaiaterrans, hydralisks symbolize the Swarm's power more than any other strain.
