Mantis screamer

Mantis Screamers were giant winged creatures native to the desolate Dinares Sector. They somehow possessed the ability to travel through space, establishing their spires on various worlds.

The Mantis Screamers were assimilated into the Zerg Swarm, becoming Mutalisks (though changing little from their original forms). Their architecture formed the basis of the Zerg Spire and their nesting form the basis of the Guardian.
