The corruptor is a squid-like zerg flying unit.
A genetic marvel, corruptors are giant brain-like creatures, with snapping beaks and dangling tentacles. Its core genus is unknown; the creature's hardened spines and webbed features suggest an aquatic background. Leviathan Brood corruptors adapted themselves to survive in high gravity environments.
The corruptor carries thick ink sacs that produce and store parasite spores, an ink-like substance that disrupts matter at a molecular level. Any vehicles or personnel doused with this compound become very vulnerable, as the atomic chains that kept them together became brittle. The corruptor can cover its targets in acid, causing them to take additional damage from attacks. This acid can cut through even the most durable of materials.
The corruptor's tentacles consist of elongated muscle fibers laden with cancerous growths. As said growths increase in size, consuming the surrounding tissues in the process, they generate a powerful electromagnetic field that warps gravity around the creature, granting it flight. If the corruptor does not regulate the growths, they are more than capable of completely consuming its tentacles. The spores stored in its ink sacs are circulated through the tentacles from time to time. This seems to inhibit (and even regress) the development of its ever-present cancerous growths. It is assumed by Dominion scientists that the creature does this to adjust its flight capabilities to new atmospheres, and to prevent the cancerous cells from consuming its tentacles.
The corruptor's ability to fly is also aided by a statocyst—a pear-shaped gland that contains a solid, mineralized mass that floated in a low-density liquid. Its walls are coated in an impermeable substance of variable viscosity, and lined with small filaments. When the mineral core inside the gland shifts due to movement or orientation changes, the liquid and the filaments provide instant feedback to the corruptor, allowing it to maintain its balance and navigate both in atmospheric conditions and deep space.
Bulbous protrusions on the top and the sides of the corruptor constitute its raw brain mass, which also function as a disposable protective measure. When something hits the tissue with enough force, it becomes a foamy substance that absorbs and redirects the kinetic energy of the impact. The damaged brain tissue is then discarded and regenerated.
Designed solely for use against aerial targets, corruptors are used against capital ships and are deeply feared by both terrans and protoss. Fortunately for the Swarm's enemies, corruptors are usually found near only the most advanced hive clusters.
The corruptor's genetic template was lost during the Second Great War when the Swarm fragmented after the Battle of Char. The brood lord, an evolution of the corruptor, was nearly lost with it; when the brood lord's template was recovered it was rebased on the mutalisk.
Despite their essence seemingly having been lost from the Swarm, Kerrigan used corruptors in her attack on a Moebius Corps facility. Furthermore, many corruptors survived among the feral zerg. During the End War, Amon enslaved a number of corruptors and used them to bolster his zerg forces.
The corruptor attacks air units and aerial structures, including units lifted by Anti-Gravity and even colossi. Corruptors are strong against battlecruisers, phoenixes, and mutalisks, but are weak against vikings and void rays. Corruption isn't used in the campaign.
Emits a stream of acid that deals 7 damage per second for 4.3 seconds, then increases to 35 damage per second.
Channeled ability. Corruptor can not move while ability is in use. Can only target enemy structures.
Exclusive to Legacy of the Void. Replaces Corruption.
Heart of the SwarmEdit
The corruptor covers a single unit in slime. For the duration, that unit suffers an extra 20% damage.
When researched, the ability starts within cooldown (so the ability cannot immediately be used).
Increases armor of zerg air units.
Legacy of the VoidEdit
In Legacy of the Void, corruptors gain Caustic Spray, an ability that targets structures and deals damage over time. The damage increases, making it nastier against high hit point buildings. This is a channeled ability.
Corruptors have a weak attack but high health. They may outlast low armor and low damage units like the mutalisk and phoenix. They are also effective against massive air units and colossi due to bonus damage and Corruption.
Corruptors should avoid void rays which have fully-charged attacks or have activated Prismatic Alignment, since void rays deal extra damage to armored units. Vikings should also be avoided for the same reason.
Heart of the Swarm CampaignEdit
The corruptor is not in the zerg tech tree in the StarCraft II: Heart of the Swarm campaign. The brood lord, in competition with the viper, may become a mutalisk evolution following the Mutalisk Evolution mission.
Corrupters also appear in Amon's forces, but with Corruption and Caustic Spray abilities.
