Sir Nighteye was a tall, lean, muscular man with sharp and elongated features. His shiny hair was always worn, smoothed down, and parted to his left, and was dark green, with three yellow streaks towards the front, two on his right and one on his left. Sir Nighteye maintained a stoic and intimidating presence with a cold and sharp glare, but that was only the side of his personality he showed in public. Even with his supposedly fierce stare, Nighteye greatly valued humor.
