In a recollection of his past as a king of the first generation, Gongseob Ji had a lean yet muscular build and a clean-shaven face. His head was not shorn, but had his black hair braided into cornrows, and his ears were pierced. He wore a ring on each pointer finger, and he wears a pair of glasses with black frames and orange-colored no-degree lens. Gongseob Ji is usually seen with a smile or rather smirk on his face.
