Queen (Legacy of the Void)

Queens (or brood queens) appear in StarCraft II, corresponding to their StarCraft I counterpart.

Legacy of the Void
Queens appear in the Legacy of the Void campaign frequently under the control of Amon, as they were among the feral zerg on Aiur that he took control of. They retain their parasite, ensnare, and spawn broodling abilities, and can also spawn creep tumors. They likewise feature in Nova Covert Ops.

Co-Op Missions
Alexei Stukov fields this kind of queen in Co-op Missions, where they are referred to as "brood queens." They serve as a support spellcaster, which can grant units detection, slow and damage units, and use spawn broodlings on ground units

A brood queen is a possible gift that can be gained during the "Gift Exchange" mutator.

Development
The queen was included in the Galaxy Map Editor for StarCraft II: Heart of the Swarm but did not appear in the game.
