A Yggdrasill is a more sophisticated version of the zerg overlord, not the least of which is its ability to exert more control over the zerg than its counterpart (30 compared to 8).


The following section contains information from StarCraft: Insurrection.

Carpenter's Brood used several to coordinate their final defense against the Zerg Swarm. The Brood was defeated, however.[1]

Game UnitEdit
