Overmind cocoon

The Overmind Cocoon was the infant stage of the new Overmind on Char. When its body was seriously wounded, it returned to its form of cocoon.

History
Infested Kerrigan and Zeratul joined forces to defeat the second Overmind. After dark templar forced to work for Kerrigan destroyed the Overmind, a cocoon emerged from it.

Zeratul swiftly slew it.

Trivia
If the second Overmind is defeated in Return to Char, it becomes an Overmind cocoon, labeled "weakened Overmind".
