He is composed and confident, and even in dire situations, he hardly falters and doesn’t appear to fear his enemies, conjuring conniving plans and strategies that result in his success. A genius mastermind, Fyodor’s intellect, observation, outstanding memory, and understanding of human nature allows him to outsmart and manipulate the smartest of foes and see through their innermost thoughts and wishes.

Nikolai 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, and he depicts great joy in fighting and tormenting. 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.

Sigma acts confident and composed even at times of crisis in front of his staff, giving the impression that he's the perfect casino manager and a capable leader.

He appears to be kind to his customers at the Sky Casino, given the fact that he gave a customer another chance by saying that the game is invalid.
