Primal hydralisk

Primal hydralisks are Primal zerg creatures that are based off the Zerg Swarm's own Hydralisk strain. According to Abathur, the primals stole the hydralisk's essence from the Swarm, and used it to produce their own hydralisks.

Primal hydralisks are very similar in appearance to normal hydralisks, though they are slightly larger and have greenish-grey carapaces.

Primal hydralisks appear as enemies on Zerus. They also appear as part of Dehaka's pack during the attack on Korhal.

Kerrigan, in her Primal Queen of Blades form, can summon sacs containing a group of primal zerg consisting of primal zerglings, primal hydralisks, and primal roaches.
