Nikolai has a pale skin, a long scar on his bluish grey left eye and a card-like eyepatch that covers his emerald green right eye, and white short hair with a long braid. He wears for winter a sage green trench coat under it a black sweater, black trousers, black boots, grey gloves and grey scarf wrapped around his neck. Nikola is sadistic and loves to speak in great theatrics. One of his main traits is his tendency to pose questions (oftentimes rhetorical threats) as "quizzes".
