Silco is a tall and lanky middle-aged man with pale skin, black hair with grey streaks styled into an undercut, a green right eye, and heavy scarring on the left side of his face. His most notable trait is his left eye, which lacks an eyelid and appears to be heavily discolored, with an orange iris and black sclera. He is also generally seen wearing a red and black Piltovan three-piece suit. Silco would often wear heavy makeup and several layers of foundation to hide his worsening scar.
