The Zerg are the second creation of the Xel'Naga, after the lizard-men-like Protoss.

History
The planet Zerus housed a small, worm-like creature, which was perfect, as the Xel'Naga were looking to make the lowest life-form "perfect", and finding the Zerg was a Godsend. They changed the Zerg from an earthworm-like creature into a parasitic worm, which supercharged the host's evolution. Wishing to avoid their earlier failure, they imposed a hive mind on their new creation. This "Overmind" soon turned against them, and almost completely eradicated or consumed them. The Zerg then learned of the Protoss, and decided to assimilate them, to become truly perfect. However, they needed a weapon. They settled on the Terrans, who were evolving into a close second to the protoss.

Larvae
The Larvae is spawned from the Hatchery. At first, the larvae can only mutate into Drones and Overlords. Drones are responsible for the harvest of reources (Crystal and Vespane), and construction of buildings. Each building adds more genetic information.

Egg
"Egg" is a misnomer. It is in fact a pupae. The Larvae has received a command to mutate into a strain of Zerg.

Adulthood
The mutated Larvae is now combat ready. Certain strains are for melee, ranged combat, or air support while others are soley meant to produce horrible poisons. Only the Hatchery/ Lair/ Hive carries out any reproduction. No zerg has ever lived out it's natural lifespan, as they are either killed in battle, or are immortal.

Varieties
There are thirteen combat sub-species of Zerg


 * Drone, responsible for collecting Crystal and Vespane, and construction.
 * Overlord, radiates Psycic energy to controll the other Zerg with. It can be evolved into a transport class unit.
 * Zergling, Small lizard, primary warrior strain.
 * Hydralisk, large snake-like beast, produces spines that are hurled with enough velocity to puncture battlecruiser grade armour.
 * Lurker, Mutated from the Hydralisk. It burrows and sends a row of vertical spikes into a target.
 * Mutalisk, primary air combat unit. Each shot is a disease, which spreads to two other targets.
 * Guardian, a bomber creature evolved from a Mutalisk. Can only attack ground targets.
 * Devourer, evolved from the Mutalisk. Can only attack air targets.
 * Scourge, a small bat-like suicide air unit.
 * Queen, a large beast that resembles a flying octopus. It is used to sow the hyper evolutionary virus, which in turn creates the Infested Terrans. It's only combat ability is spawning a pair of insects on a ground unit.
 * Defiler, a scorpion-shaped crerature. It carries the gene codes of every Zerg, which it uses to produce carciogenic poisons.
 * Ultralisks, a large elephantine beast. it is clased as a seige unit, although it is a melee attacker.
 * Infested Terrans, a zombie-ish suicise bomber. it produces chemicals that are not only horribly toxic, but explosive as well.

Hive Mind
The Xel'Naga were concerned that the individuality of each Zerg would cause a war. So they imposed a hive mind on their creation.
