The devourer is a zerg anti-air flyer.
Devourers are an evolution of the mutalisk. In use by early 2500 during the Great War, devourers spit a venom of corrosive acid at aerial targets that can eat through the reinforced armor plating of terran and protoss capital ships. A single spit of venom may splash over multiple targets. The acid spores in the venom may hinder the fighting ability of the target.
Heavy Assault Flyer
Devourers are the anti-air aspect of the mutalisk. They are slower than mutalisks but faster and more resilient than guardians.
The devourer's attack has the additional effect of attaching "acid spores" to anything it hits. A unit affected by spores will be revealed (if cloaked), have its attack speed slowed by 1/8 per spore, and take 1 point of additional damage from every attack for every spore attached. A maximum of 9 spores may affect a target at any one time. Spores will disappear after a period of time.
The fast firing and bouncing attack of mutalisks benefit greatly from the acid spores. Against a group of targets splashed with 9 spores a single mutalisk can deal 18 damage on its first attack instead of the normal 9 damage, this also applies to the mutalisk's second and third attack which makes it effective take out high armor targets faster, like battlecruisers and carriers, and able to go toe to toe with area-of-effect anti-air units like corsairs and Valkyries.
Devourers have a very slow rate of fire, and the attack travels slowly. If a devourer moves before the glob of acid strikes, the glob disappears. The devourer's slow speed and rate of fire also makes it vulnerable to hit-and-run attacks from groups of scouts and wraiths.

Wings of LibertyEdit
Heart of the SwarmEdit
The devourer was not included in the campaign, but can be found in the Galaxy Map Editor for StarCraft II: Heart of the Swarm. It remains an air-to-air unit, but would mutate directly from a larva instead of the mutalisk. It has the same corrosive acid effect as in the original game, splashing targets with acid spores that reduce the armor of units by 1 and their attack speed by 0.1 for each spore. The effect can stack up to 20 times. The devourer has three upgrades associated with it that are tentatively tied to the evolution pit:
- Gaping Maw: Devourer's attack speed increases by 25%.
- Improved Osmosis: Acid spore debuff lasts twice as long.
- Prescient Spores: Devourer can attack ground units.
Devourers can be seen in the background from the leviathan on Char once Warfield's fortress has been destroyed, and in glass tanks in the Umojan research facility.
