Dance Partner Fyodor

Fyodor Dostoevsky (フョードル・ドストエフスキー, Fyōdoru Dosutoefusukī?, Russian: Фёдор Достоевский, Fyódor Dostoyévskiy) is the leader of the Rats in the House of the Dead and a former member and founder of the Decay of the Angel. His ability is named Crime and Punishment.

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, 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.

Overall, Fyodor is a self-interested, manipulative, and enigmatic man whose manipulative tactics relies on the desires and goals of others rather than loyalty, respectful leadership, or genuine friendship. As Dazai suggest, Fyodor doesn't trust anyone he can't manipulate which is the sole reason why doesn't have any genuine friends or allies[16].

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 "Fyodor Dostoevsky"[13]. In the far past, as seen through Sigma's ability, he witnessed Dostoevsky's execution by a solider and his blood spilled on the man as he died. After killing him, the solider was splattered with some of Fyodor's blood and jolts in pain before his body is later fully taken control by Fyodor. This ability allows Fyodor to live for an incalculable number of years considering how old the memory Sigma witnessed of him using it is [15][17][13].

The oldest known piece of background Fyodor has predated to when he was captured by Bram Stoker and his men. Bram's executioner kills Fyodor, but Fyodor uses his ability to take over the man's body.[13]

At some point in time, Fyodor manipulated Fukuchi by creating a fake prophecy about a world war happening in 36 years.[18] This urged Fukuchi establish the Decay of the Angel and enact the global terrorism.

Fyodor was mentioned to have been met Osamu Dazai at an unknown point in time.[19] Three years prior, Fyodor first met Sigma, who had been born by power of the Book. The Russian asked him if he wished for a home, an offer that Sigma accepted.[20]

Later, Fyodor apparently allied himself with the Guild in an attempt to acquire the Book, presumably together with the Order of the Clock Tower.[21]

The name Fyodor (Фёдор) means "divine gift". The surname Dostoevsky (Достоевский) means from Dostoev, Belarus.

He appears to have a habit of biting the tip of his thumbs, making them bleed. According to him, he possesses 'a weak anemic constitution', in other words, anemia. He plays the cello. [25]
