Brakk

Brakk was a primal zerg pack leader on Zerus.

He is a huge primal ultralisk with great physical strength. He also was quite intelligent as he was quick to work out that destroying the quilgor packs and subsequently there meat would be an efficient way to stop the plan of Sarah Kerrigan to awaken the Ancient One Zurvan (likely because Brakk feared Zurvan). He had one Achilles heel however, his anger and short temper. As Sarah Kerrigan proved to be efficient both in gathering the quilgor meat and at the same time fending of his raiding parties Brakk's anger continued to grow with each piece of Quilgor meat that Kerrigan successfully fed to the ancient one. After Sarah Kerrigan fed the ancient one the last piece of quilgor meat he (being overcome with anger that the broken and corrupt zerg could defeat his pack) personally led a final attack on Sarah Kerrigan's hive cluster. The attack failed and he was killed by Kerrigan.

During the Second Great War, Sarah Kerrigan intruded on its territory while awakening Zurvan. Kerrigan killed it when it obstructed her.

The remnants of Brakk's pack were destroyed shortly afterwards by Yagdra's pack.
