  • Cocoon, the name of the default larva eggs in StarCraft II

A cocoon is a zerg protective cover formed by mutalisks when mutating into a guardian or a devourer. The creature remains suspended in mid-air. It has less armor than an egg. Although cocoons are flyer units, their armor upgrade is affected by a carapace upgrade, not flyer carapace.
