Disguise: Gogol is capable of disguising himself enough for other people not to notice it. This can be seen when Gogol disguised himself as a police officer in order to approach the car Mushitarō Oguri was in without raising alert or suspicion.[4] He also disguised as Tonan's secretary for a half a year.[2]

Gogol 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". He is also skilled in disguises, deceiving Tonan as his secretary.[1] Whilst fighting Atsushi Nakajima, Gogol depicts great joy in fighting and tormenting him, going as far as to capture Atsushi's leg in his coat and leaving it in a separate space on the floor.[2]
          
          Gogol hints that his eccentric persona may or may not be real. The side of him feeling no remorse in murdering others is just as real as the side that feels guilt, well aware of how wrong and cruel his actions are. He claims to want to soar as freely as birds do. Nonetheless, both sides appear evident. However, even if he does feel guilt, he acts as if he bears no hard feelings towards Fyodor Dostoevsky, whom he nicknames "Dostoy".
