Once the best friend of Bayan-Tal, the sith lord Darth Locuss now craves nothing less than galactic supremacy. He considers himself a "higher class" sith lord and believes that all other life should conform to his will. While much of his body has been replaced with biomechanical components, the most notible change is his left arm. It is connected from shoulder to elbow and elbow to wrist by the same light crystals within lightsabers. This gives Darth Locuss and edge during lightsaber combat, as he is able to deflect attacks with his arm.
