Technobeast

Technobeasts were part machine, part organic Sithspawn mutants. They were created by infecting living organisms with the nanogene spore, a technovirus developed through a combination of Sith alchemy and a Force technique called mechu-deru. The virus grew metallic tumors over the bodies of its victims, ultimately lobotomizing their brains and transforming them into weaponized cyborgs. Living subjects from a number of different species were infected by the virus, spawning mutated amalgamations of metal and flesh in a variety of shapes and sizes.

In the last quarter of the New Sith Wars, a Dark Lord of the Sith known as Belia Darzu devised a dark side ritual called mechu-deru vitae, using it to build her own army of technobeasts—the Metanecrons. Housing the creatures inside a hidden stronghold on the planet Tython, Lord Darzu used her army of mutated cyborgs against the Galactic Republic and the Jedi during the two-decade Sictis Wars. The subsequent assassination of Darzu ended the creation of new Sithspawn hybrids, leading to their disuse after the conclusion of the New Sith Wars.
