Dehaka's pack is highly evolved, having taken many traits and essence from the Zerg Swarm after Sarah Kerrigan's arrival on Zerus. Dehaka's pack has had its breeding and evolution guided, and Dehaka has made it a goal to create creatures in his pack similar to banelings. The pack has evolved beyond the need for primal overlords.
The Second Great WarEdit
The pack consisted of the first primals that sided with Sarah Kerrigan when the Zerg Swarm visited Zerus during the Second Great War. After Kerrigan's transformation into the primal Queen of Blades, Dehaka recognized her strength and offered to serve her in exchange for new essence. As part of this agreement, he sent his pack to assist her in killing the other primal leaders on Zerus. After the death of their respective leaders, the other primal packs joined the Swarm as well.  When Kerrigan and the Swarm returned to the Koprulu sector, Dehaka and his pack went with her, seeking new essence to consume.
During Kerrigan's invasion of Korhal, the Terran Dominion used its Psi Destroyer to attack the Swarm. Because Dehaka and his pack had no psi link, they were immune to the Destroyer's effects. Kerrigan sent Dehaka and the other primals to infiltrate the Dominion's lines and disable the Psi Destroyer's power generators. Dehaka's pack surprised the terran forces guarding the Destroyer and destroyed the three generators powering the device. Kerrigan's forces then moved in and destroyed the device itself.
