Primal ultralisk

Primal ultralisks are primal zerg lifeforms similar to ultralisks.

Appearance

They look drastically different from their Zerg Swarm counterparts, being significantly smaller, possessing lower health, and lacking the large shield-like carapace above a normal ultralisk's head. They also attack differently, as their kaiser blades, instead of being mounted to their backs, are attached to their front legs in the form of large, retractable claws. They also look more similar to ravasaurs, Brakk and Tyrannozor.

History

The primal ultralisks first appeared during the first engagement on Zerus, as part of Brakk's pack.^[1] Later they appeared as part of Dehaka, Yagdra, Slivan and Zurvan's packs.^[2]^[3]

During Kerrigan's invasion of Korhal, several primal ultralisks assisted Dehaka in disabling Mengsk's Psi Destroyer. ^[4] Primal ultralisks also participated in the final assault on Augustgrad.^[5]

Burrow

Many zerg ground units may burrow, becoming invisible and revealed primarily by detectors, and may not move or attack while burrowed.

Exceptions include:

Roach, which may move while burrowed
Lurker, which may attack while burrowed
Infestor, which may move while burrowed
Baneling, which can detonate while burrowed.

Some units can unburrow via autocast, causing them to emerge and attack when an enemy moves into range.

The ability is not smartcast.

Development

The primal ultralisk originally had a "Devour" ability, where it swallowed a non-massive enemy unit. The enemy unit would not be destroyed, but would be removed from battle and take damage over time as long as it remained swallowed. Destroying the primal ultralisk frees the swallowed unit.^[6]
