Nikolai is eccentric, funny and childish, which does not contrast with his cold, sadistic and psychopathic side. He seems to know that killing is wrong, but still he continues to do it for fun. and he loves to speak in great theatrics. One of his main traits is his tendency to pose questions (oftentimes rhetorical threats) as "quizzes". Nikolai is overly dramatic. He takes most of his actions as a joke, he like tease anyone and everyone, especially if it means that he can get a laugh out of it.
