The Vortex are large, cephalopod-like creatures with green skin and large, oblong, bulbous heads. They have four grasping arms and a central tentacle. The queen resembles the drones, but is much larger, far larger than the bottlenose dolphin who defeated her, and more aggressive. There are also warrior drones, which are heavier and armored in comparison to the worker drones. They are brown in color with two arms that each end in a pair of long, sharp claws, and they have a long, stinger tail.
