 Control can be re-asserted over feral Zerg by a Broodmother or other command strains however.A second Overmind is created in "Brood War", formed from the merging of several cerebrates.This second Overmind never reaches full maturity, and thus lacks the power and intelligence of the original and is much weaker; attacks that were superficial to the first Overmind send the second into remission, although dark templar energies are still needed to kill it.
