Vokdara

The Vokdara are basically unintelligent versions of the Borg. They absorb living matter (gelatinous cube-style) and randomly (at an infrequent but not rare rate) incorporate entire systems into their own selves. The Vokdara constantly fight, so any incorporated system that does not aid them in combat in some way will be quickly removed from the population. Eventually, they will become a fearsome and deadly foe to all of existence, but for now they remain a slowly evolving menace. They currently live on the planet Vok.
