Sukuna

Sukuna or Double-Faced Specter is one of the primary antagonists in Jujutsu Kaisen.

Known as the undisputed King of Curses (いの), Sukuna, according to legend, was a demon (though in truth was a human Sorcerer) during the prime era of Sorcery 1000 years ago, and Sorcerers gave their all to defeat him. After his death, his corpse was unable to be fully destroyed, and thenceforth his 20 fingers, preserved in grave wax, traversed the ages as Cursed Objects. In the present, Sukuna has incarnated into Yuji Itadori due to the latter eating one of his cursed fingers, which contain his fragmented power.

Appearance
His past appearance is described as a demon with four arms, and two heads. Currently,he appears similar to the host he is in (Yuji Itadori), but with spiked hair and with special marks/lines on his forehead, nose, cheeks and torso. He also has a second pair of eyes under his normal eyes, which are usually closed. Sukuna also has two lines on both his wrists, upper arms, circles on both his shoulders with a dot in each, two segmented curve lines on his chest, and two lines are his stomach while possessing Yuji.

Sukuna wears a light-colored kimono with a black edge, a black scarf, and black shoes.

Personality
Sukuna has a sadistic personality and likes to see others suffer. He is also greedy, and always wants to stay in control of the situation without caring about the consequences.

Abilities
Sukuna is a Special Grade Cursed Spirit. As the most powerful curse, Sukuna has a vast amount of Cursed Energy.

Physical Power

 * Strength: In Yuji's body he possesses a superhuman force, and managed to fling a person through several floors of a building without effort.


 * Speed: Sukuna has shown to move at incredible speed, which his opponent doesn't even notice that Sukuna has moved until it is too late.
 * Reflex: Sukuna can easily counter any opponent, and has shown to counter his opponent before they realize that their limb has been cut off.


 * Regeneration: Sukuna has shown the ability to regenerate his host body, regenerating his entire hand or creating a new heart.


 * Metamorphosis: Sukuna can create new eyes and mouths on his host, allowing him to see and speak without having to control the body of the host.
 * Durability: Sukuna was punched through five buildings and shown to be complete fine.

Jujutsu
Cursed Technique: It is currently unknown what Sukuna's Cursed Technique is. Sukuna has shown to use his cursed energy to slash targets with, which he has two types with. He was also shown to use fire-based powers.
 * Dismantle: Sukuna's default slashing attack.
 * Cleave: A slashing attack that adjusts itself depending on the target's toughness and cursed energy level to cut them down in one fell swoop.
 * Unnamed Fire Ability: Sukuna has been shown to be able to manipulate fire for long-range attacks.

Sorcerer Techniques: These techniques are ones that any Sorcerer is capable of using.
 * Domain Expansion: A technique where Cursed Energy is used to construct an innate territory with technique that spans the surrounding area.
 * Malevolent Shrine : Sukuna's Domain Expansion, creates a Buddhist shrine decorated with skulls. Malevolent Shrine is different from other types of Domain Expansion, in that it doesn't create a separate space using a barrier. By allowing an escape route, a binding vow is formed, which vastly increases the guaranteed hit's effective area with a maximum radius of nearly 200 meters.

Trivia

 * Sukuna is based on the same-named figure from Japanese mythology: Ryōmen-sukuna. He is a demonic/specter-like figure described in the Nihon Shoki, who was said to have appeared in the Hida Province (today's Gifu Prefecture) in ancient times, during the reign of Emperor Nintoku.
 * He was described as a man of monstrous strength, with a two-faced head plus a total of eight limbs, four arms and legs respectively that served each face. Wielding a multitude of weapons in his many hands (incl. a bow, arrow, and sword), he terrorized village after village, plundering and leaving chaos in his wake. That is, until a brave military commander dispatched by the Imperial Court, named Takefurukuma, stepped forth and put an end to the monster's tyranny, expelling him from Hida.
 * Ryomen-sukuna was worshipped by some as a minor deity, and statues depicting his distinctly two-faced head can still be found today in temples and shrines in Gifu.
 * Sukuna's kimono is very loose akin to a ladies' kimono, as such space granted him more comfort while having four arms in the past.
 * Sukuna ranked 10th place in the manga's 1st Character Popularity Poll with 5,860 votes.
