A scourge

The scourge is an aerial zerg kamikaze strain.


A scourge during the Great War

Scourges are blind (due to optical degeneration)[1] suicidal fliers of unknown origin, seeking out enemy starships and diving into them. Catalytic agents within the scourge allow it to undergo a form of plasma metamorphosis, causing it to explode like a living bomb.[2] A single scourge is capable of destroying a terran starfighter or shuttle and a handful can breach the hull of a starship. They are able to engage these targets in both air[3] and the vacuum of space.[4] On the ground, scourges stand taller than a terran in CMC armor.[1]

The primary drawback of the scourge is its limited ability to store energy, able to fly for barely a few hours without requiring additional substance. To conserve energy, they often perch on the backs of overlords. However, this presents a hazard, as the scourge's explosive nature can damage friendly zerg at this proximity.[3]

A scourge during the Second Great War

Scourges have a varied and somewhat confusing evolutionary history.[1] They possess a simple genetic makeup, allowing them to spawn in pairs from a single larva similar to that of zerglings.[2] By the Second Great War, scourges could be spawned from leviathans.[5] By 2505, it appears that the Swarm had settled on dedicated scourge nests to handle scourge evolution and production. These nests were spotted in Char's infamous Bone Trench, but it was unclear to the Dominion whether these nests actually spawned scourges, or if pre-existing scourges had chosen to nest in them.[1]

Scourges replace the Ragnarok Missiles of Tychus's "Summon Odin" ability when the Infested Tychus skin is used in Heroes of the Storm.[6]


In earlier versions of StarCraft, guardians and overlords would spawn scourges upon death. In StarCraft II, Zagara's corruptors spawn scourges upon death.
