Kilysa Brood

The Kilysa Brood is a zerg brood under the command of broodmother Kilysa and leader of the Kilysa Brood. The brood is small but has many leviathans. Initially splitting off from the Zerg Swarm after Kerrigan's de-infestation, Kilysa later requested to rejoin the Swarm upon learning of Kerrigan's rebirth as the Queen of Blades. Kerrigan ordered her to destroy Mistaff IV, a hub of Dominion military production to gain a place in the Swarm. Kilysa obeyed, and her brood attacked the planet. Her brood also attacked Cruxas III.

During the invasion of Korhal, Kerrigan ordered the Kilysa Brood to have her leviathans set up a blockade around the planet and fend off any incoming Terran Dominion reinforcements.
