Dehaka

Dehaka is a primal zerg pack leader from Zerus. He was among the last of the primal zerg pack leaders.

Dehaka is bipedal, with a very small right arm.

Biography
After Sarah Kerrigan acquired the power of Zerus and was reborn into the Zerg Swarm, Dehaka perceived her as the strongest of zerg and joined her, bringing his pack with him.

For the pack leader, the journey to the Koprulu Sector was a chance to absorb additional genetic material and "essence". He saw terrans as weak, genetically unremarkable, and disdained their use of technology and artificial weaponry. Dehaka claimed to be able to direct his own evolution, growing talons and armor plating to counter his enemies.

As with all primal zerg, Dehaka lacked any connection to a hive mind. This trait proved invaluable during Kerrigan's invasion of Korhal. Arcturus Mengsk deployed a Psi Destroyer, killing any zerg within its radius connected to Kerrigan. Immune to its effects, Dehaka neutralized the Psi Destroyer, allowing Kerrigan's Swarm a foothold on Korhal.

Trivia
Dehaka might be named for Azi Dahaka, an evil figure in Persian mythology.

It's possible catch a glimpse of Dehaka in Waking the Ancient. He will leap from a cliff and burrow underground.

The player can find his large bleeding right arm in the mission Supreme.
