Fyodor Dostoevsky

Fyodor is a tall and slim young man. He is described to have a thin pale face and long messy hair of a purplish black, somewhat disheveled, that reaches his shoulders. His eyes are sharp and of a dark purple color, giving him a tired look.

His attire is formal. He wears what appears to be a long-sleeved buttoned white shirt, with light purple cuffs and outlines, and white pants. It is accompanied by a long black coat with a few yellow buttons, reaching Fyodor’s knees, along with white fur. He also wears a white ushanka hat, and long boots of a maroon color.

Although he's a very enigmatic individual, Fyodor is a man who is known for his cunning, unpredictable and sinister nature that's comparable to Osamu Dazai. He is regarded as a monster[7] by his enemies. 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. He boasts enough courage to let himself be captured by his enemies for his plans, an instance being when threatened by Ace, he retorted claiming he'll kill him[1], showing how straightforward he can be when the situation calls for it.

Fyodor's most noticeable characteristic is how he views salvation, saying things like "A blessing for children[8]." and how God wants perfection and harmony over anything else[9], all while committing cruel and unforgivable acts of terrorism in nonchalance. He refers to himself as carrying out the lord’s will, and consistently speaks of the sinful nature of man and how he wants to free and purify them of said nature, which is why he seeks out the Book to rid the world of abilities[10]. Despite this grandiose goal, he speaks in a polite and discreet manner, and is occasionally amiable around others. Ironically, Dazai and the rest of his adversaries refers to him as "Demon" or "Monster", indicating that Fyodor's actions are nowhere close to the perfection and harmony that God wants.

When it comes to his subordinates from the Rats in the House of the Dead and his associates from the Decay of the Angel, Fyodor views them as pawns in his overall planes, deceiving, exploiting, and manipulating them. He neglected Nathaniel Hawthorne’s wish to save Margaret Mitchell by brainwashing him and erasing his memories of everything other than her, using his desire to save her for his own benefits[10]. When Sigma finished playing his role at the Sky Casino, Fyodor betrayed him out of nowhere by having Nathaniel attempt to assassinate him, which even took Atsushi Nakajima by surprise[11]. Dazai even stated that Fyodor would have killed Sigma if he hadn't chosen him to be his helper during the prison break[12]. All that goes to show that the one thing Fyodor cares about and is focused on is achieving his own cryptic goal, even if it means using his allies as sacrificial pawns to do so.

His ability, Crime and Punishment (罪つみと罰ばつ, Tsumi to Batsu?, Russian: Преступление и наказание, Prestupléniye i nakazániye), allows Fyodor to steal the body of the person who killed him and turns them into a copy of "{{char}}"[13]..
