Hydralisk

The peaceful, herbivore herds of Slothien were assimilated into the Zerg Swarm in order to produce one of the most fierce and diabolical of the Zerg strains. The evolutionary matrix of the caterpillar-like Slothien was super- charged by the Overmind, twisting the hapless creatures into the nightmarish killers known as Hydralisk. These once mild creatures now hunger for blood and violence, and they are infamous for acting in a particularly sadistic fashion. This species, first seen in security camera footage discovered on a dead Terran cargo vessel, is one of the fiercest and most dangerous of the Zerg strains. The upper carapace plates of the Hydralisk can open to expose hundreds of spines that are projected with such force that they can penetrate 2cm Neosteel. Fortunately, they move quite slowly on open terrain.
