Metanecrons

The Metanecrons were an army of mutated cyborgs—technobeasts—formed by the Dark Lord Belia Darzu during the New Sith Wars. Using Sith alchemy and mechu-deru, Lord Darzu created this army by means of a technovirus called the nanogene spore. Contained inside a hidden stronghold on the planet Tython, living victims from a number of different species were assimilated into the Dark Lord's forces. As the leader of a resurgent Sith faction, Lord Darzu unleashed her technobeasts upon the Galactic Republic and the Jedi during the Sictis Wars. At the end of this period, the assassination of the Dark Lord ended the creation of the mutated hybrids, sabotaging her cyborg army. Centuries later, the remaining bulk of Darzu's technobeasts dwelled inside her fortress on Tython, only to be wiped out at the hands of the Sith Lord known as Darth Bane.
