"A disgusting primal zerg leader that endlessly births swarms of minions. Emotionless, distant and quiet. Very disturbing and unsettling undertones to everything she says."

- Character description(src)

Slivan, the Eternal Mother was one of the primal zerg pack leaders of Zerus. She was described as "hollow and destructive" by Zurvan.


" your demise."

- Slivan confronting the Queen of Blades(src)

After Sarah Kerrigan's rebirth on Zerus as the primal Queen of Blades, the primal pack leaders sent most of their forces against her Swarm, leaving themselves vulnerable. While Zagara defended Kerrigan's leviathan against the primal forces, Kerrigan, aided by Dehaka's pack, set out to challenge the pack leaders personally. After killing Yagdra and Kraith, Kerrigan came for Slivan. She fought her way through Slivan's pack, before battling and killing Slivan herself. Kerrigan then absorbed Slivan's essence.[2]

Game Unit[]

Heart of the Swarm[]

"More! There must be more!"

- Slivan's combat strategy(src)

Slivan is a larger version of the swarm host and spawns virtually endless waves of creepers, which are the primary obstacle on fighting her; the player must keep moving about to avoid being overwhelmed by the exploding creepers.

On her own, Slivan moves slowly and has the lowest HP of the three pack leaders. She has no innate attack, but an Acid Vomit ability that functions as her main attack. Acid Vomit creates a lasting slime puddle that slows all units that walk through it and deals damage over time.

As with the other pack leaders, Slivan's remaining minions will die once she is killed.[2]

The following section contains information from Heroes of the Storm and is not canon to StarCraft continuity

Slivan appears as the final boss of the "Escape from Braxis" brawl in Heroes of the Storm. She uses the generic mercenary swarm host skin.


  • If viewed in the map editor, the creeper sacs on Slivan's back take on team colors.
  • Initial concepts for Slivan were of a "much more disgusting, larva-based monster." However, as development of "Supreme" was taking a large toll on the development team, Slivan's model was decided to be that of a swarm host.[3]
