Il-Hwan was a handsome and muscular middle-aged man with gray eyes, shaggy black hair, and slight facial hair. When using his powers or agitated, his eyes glowed bright yellow. During his time on the run, Il-Hwan wore a tattered brown cloak over a ragged white undershirt, white bandages on both hands, baggy black pants, and a pair of black boots. In contrast, before he went missing, Il-Hwan sported a much cleaner look and was pictured wearing a brown jacket over a simple black undershirt.
