Zerg egg

Various zerg eggs

The zerg egg, also known as the zerg cocoon, is the basis of all zerg units other than larvae, post-Brood War queens and infestation units. They exist only for a short time: they are created when a larva is given an order to morph into a unit and burst to give birth to the ordered unit.

Overview

A zerg egg

Most zerg units are morphed from the larvae. When one is given an order to morph into a unit, it encases itself in a soft yet extremely protective cocoon that is very difficult to destroy, entering its pupal stage as it transmogrifies its own body into the ordered unit. When the morphing is complete, the egg ruptures and the unit bursts out of it.

There's many types and versions of zerg pupal forms. Known types are: Egg, chrysalis, infested cocoon, cocoon, lurker egg/lurker cocoon, Overmind cocoon, and more recently, baneling cocoon, brood lord cocoon, infested swarm egg, impaler cocoon, and overseer cocoon.

Primal zerg incubate and spawn from similar eggs.

Zerg eggs were transported through the hive via birthing tubes. When damaged, these tubes would close to prevent future use.

Larvae morph into eggs when ordered to "train" units. Unlike other races, the unit can be killed during training by destroying its egg. Eggs retain the heavy armor of larvae, and require concentrated fire to be destroyed.

In StarCraft II, eggs are called cocoons. Larvae morph into eggs when "training" a unit.

Each individual egg can be separately rallied; this overrides rally points set for the hatchery.

In Co-op Missions, Alexei Stukov's infested terran structures spawn several eggs called "infested cocoons." Stetmann uses mechanical zerg eggs named mecha eggs.

Variants

• Mecha egg (terran replicant)

Notes

• According to Bob Fitch, eggs were initially planned to be spawned from the queen, who would lay them similar to the Queen from the film Aliens. However, it was deemed too hard to replicate the look and feel, and production was moved to the hatchery. Larva were added as a "temp state" for eggs in order to not have it look as if eggs appeared out of nowhere.
