Fiction:Kra'Dion Swarm

The Kra'Dion Swarm is a huge collective of insectoid creatures that spans the entire galaxy. Individual Hives are relatively weak, but if one or more swarms joins forces then the resulting collective is strong enough to threaten minor space powers. Perhaps the most terrifying aspect of the Kra'Dion's remorseless advance is the sheer mindless will with which they go about their slaughters. The warrior drones, the Anakoma, are completely devoid of emotion, and so do not feel fear nor guilt. The control of the Kra'Dion Hive Mind is so powerful that it can even control an organism's body for a few hours even after its controlling consciousness is long dead.
