Primal mutalisks are the primal strain of the mutalisk.
They possess four wings and they resemble wasps, unlike the Swarm mutalisks, which have a different tail and have only two leathery wings. 
Game Unit Edit
Heart of the Swarm Edit
In combat, primal mutalisks are identical to their normal counterparts in the Swarm, but do not benefit from the mutalisk's upgrades in the
evolution pit. They also cannot evolve into brood lords or vipers.
Primal mutalisks appear as part of
Brakk's pack, and later Yagdra's pack on Zerus.  Later, they appear as part of  Dehaka's pack on Korhal.
Co-op Missions Edit
Primal mutalisks can be constructed by
Dehaka in Co-op Missions. They are evolved from primal hydralisks. They can evolve the following traits:
Primal mutalisks deal 50% increased damage against air units.
Primal mutalisks take 50% less damage while moving.
Primal mutalisks revive on death after a short time. Cannot occur more than once every 60 seconds.
