Technobeasts were Sithspawn created by the Dark Lord Belia Darzu, and were considered the most frightening aspect of the Sictis Wars. Darzu was able to develop a technovirus that immediately began to turn the organic creature into a droid hybrid.
The frontal lobes of the victims’ brains were lobotimized by the virus, making them incapable of higher thought, by which point the process was irreversible. While Technobeasts were never alike, they often had sharp protrusions on their arms, by which they could infect others. Some were even designed to release a cloud of the technovirus in combat.
