The defiler

The defiler is a zerg breed that uses toxic substances to support other zerg forces.


Defiler SC1 Art1

A defiler during the Great War

The defiler is a relatively rare zerg breed, resembling a silverfish in appearance and acting akin to a 'cancer factory' in function.[1] Its core genus, if it has one, is unknown, as the defiler contained the DNA of all other zerg breeds.[2] It was created from festering, carcinogenic pathogens that were, in essence, leftover genetic chains from other zerg strains.[3] It used this genetic material to synthesize virus-like biochemicals.[1] These biochemicals were extremely hazardous, resistant to the most effective anti-toxins, and, paradoxically, dangerous even to the zerg.[1] A large amount of energy was expended in the production of these chemicals,[4] and defilers were known to cannibalize other zerg to fuel the metasynaptic processes that generated the compounds,[2] often accompanied by zergling escorts for this very reason.[1] They could also recharge the metasynaptic processes through burrowing.[4]

The defiler's body was host to countless small organisms that lived on the carapace, constantly feeding on each other.[2] The defiler could spontaneously launch a number of these creatures to swarm a location that make it difficult to target anything under the ensuing cloud. In addition, defilers could produce corrosive spores and hurl them at a target area, the spores exploding in a dense cloud. The highly toxic mist that resulted corroded anything it touched.[2] The spores were also prone to igniting due to a flammable accelerant contained in them.[5]

A defiler

Moving with a slow, intelligent slither, defilers were highly vulnerable to any form of counterattack (especially long-range or air assaults) and as such, usually stayed at the rear of zerg formations.[4] The defiler evolved into obselescence after the Brood War. However, with the need for a specialized support strain, the zerg revisited the defiler template and perfected it with genetic data from an unknown species, preserving its core functions while excising its unnecessary lethality.[3] The result was the viper.[6] Feral defilers still existed after the End War however, and the Defenders of Man used psi-emitters to lure them to Borea.[7]

The following section contains information from StarCraft: Retribution.

Defilers possessed the ability to extract and process information from terran minds.[8]

Variant StrainsEdit



In StarCraft II, an untextured model of the defiler was included in the Galaxy Map Editor for StarCraft II: Heart of the Swarm.[9] The model is identical to the model later used in Covert Ops.

Defiler bones

The bones of defilers appear in Wings of Liberty as zerg research objectives in the level The Great Train Robbery, and in the Heart of the Swarm mission Fire in the Sky as evolutionary objectives for Kerrigan.[10][11]
