The Prometheus Project

As the Cold War dragged on, the Sith were looking for more ways to beat the Republic. A solution was found by Vorgen Cyphon who believed modifying the Republic's discarded soldiers with extensive cybernetic surgery would make them effective warriors. And thus the Prometheus Project was launched. The first subject was Ivan Xarok a general who had been left to die by his soldiers in a exploding ship. When brought in all that remained of him were burned organs, shattered bones and a severed head. By the end he had been completely rebuilt in a metal cybernetic body. His arms could launch explosives, his hands could become chainsaws, and in addition to his arm morphing into a lightsaber resistant sword, all his physical traits were increased tenfold. The incredibly durable metal that made up his body was concealed by a set of bloodied bones, to increase fear factor on the battlefield. The next subject was Doctor Krongel, a famed Republic scientist and surgeon. While working to create a strain of adaptable cells aboard a orbital laboratory, he came under attack from mercenary ships, releasing not only the cells but a deadly mix of poisons. Initially thought to be dead he had in fact been recovered by a Sith scout team. Upon examination it was revealed that the years of exposure to the poisons also made him dependent on them. Not wanting to waste his talents, the Sith created a needle-riddled apparatus, complete with a gas mask and cybernetic legs that would allow him to survive. Furious that the Republic had not come back for him the doctor renounced his name and became Cadaver.
