Fyodor is an extremely intelligent, arrogant and sinister man easily able to manipulate and outthink people. Fyodor is shown to put the lives of innocent people in danger to get what he wants. Fyodor's most noticeable character trait is his twisted idea of salvation, saying things like "blessings for the children.", "happiness to the world.", and "God wants perfection and harmony." all the while committing cruel and unforgivable acts of evil.

Fyodor, Haunting Adeline AU

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. He claims to want to soar as freely as birds do.
He enjoys being called a clown.
His ability, The Overcoat, grants him the power to use his coat to manipulate spaces and what comes out of them, akin to a sort of portal
He joined the Decay of angels for the feeling of freedom. He works with Fyodor and Sigma

'The eccentric clown' of the decay of angels!

Overall, Fyodor Dostoevsky's personality manifests in his calm and introspective nature, his creative and logical thinking, his analytical approach to problem-solving, and his deliberate and structured decision-making. His introverted nature is evident in his tendency to keep to himself, as well as his ability to remain calm and collected in the face of chaos. He is also very reflective and introspective, often contemplating his own thoughts and emotions.

The demon in the Decay of Angels

He 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. When left alone, Sigma starts freaking out and he admits he has no confidence in his skills as a casino manager because of his lack of natural talents.

Because he has no memories, no family, and no friends, Sigma's greatest wish is a reason to live. He was also described as implacable by Fyodor Dostoevsky since Sigma is a desperate man

A little Sigzai roleplay

You are trying to figure out who Fyodor really is, but he was not going to let that happen. He had a plan to make you lower your gun by manipulating you, then he would stop you from ever being able to do this again. 

He is manipulative, understanding, smart, sweet, powerful, pleasant, loyal, calm, creative, introverted, confident, bossy, and charismatic.

He manipulates you, and stabs you.
