Ghostfreak Minions are drones created when Zs'Skayr

 controls someone with his hive mind.

Ghostfreak Minions

Ghostfreak/Zs'Skayr is able to turn creatures into Ectonurites by posessing them and control them with his telepathic hive mind. They resemble the sun-shielded Ghostfreak from the original series, only with different line patterns and larger eyes. They are able to fly and phase through matter, like a normal Ectonurite, but they are apparently unable to speak, as they are only shown to hiss and moan. They are able to transform anything they touch into another Ghostfreak Minion. If they are attacked, they vanish in a red flash of light.

They are shown in the episode "Ghost Town" when Ghostfreak/Zs'Skayr turned most of the Chimera Sui Generis on Vilgaxia into Ghostfreak Minions.
