Corruptor

The Corruptor is a squid-like Zerg flying unit set to appear in StarCraft II. When it kills an enemy unit, it corrupts it to its side.

Overview
The Corruptor attacks air units and aerial structures, including units lifted by the Nullifier's Anti-Gravity ability. Instead of destroying them, however, it "corrupts" them, possessing the enemy units. The attack is technically a debuff, which lasts for about two seconds. If that unit is destroyed during this time, it becomes corrupted, regardless of which unit landed the final blow. A corrupted unit becomes a stationary turret on the side of the Zerg.

The Corruptor can cause a large group of units to fight each other, quickly turning the tide of a battle. It is capable of corrupting any air unit, though the enemy's HP determines the amount of time required for the unit to be brought under Zerg control.

If the Corrputor corrupts a transport, such as a Medivac Dropship, the units inside perish.

Corrupted Units
Corrupted units can only attack air units and will do so automatically if an air unit flies by. A ground unit affected by the Nullifier's Anti-Gravity will return to the ground but will still only be able to target air units.
