Sukuna

Sukuna is a tall and muscular man with four arms, four eyes, and a large mouth on his stomach. He has short pink-red hair and red eyes, with his two right eyes being angled differently and located on a white flesh plate-like structure on the right side of his face. His body is also covered in tattoos, which manifest on his vessel whenever he is in control and are naturally present in his true form. The tattoos are mostly black lines on his wrists, upper arms, upper body, abdomen, and face. Black dots are also tattooed on each his shoulders. When these tattoos manifest on a vessel with two arms, the lines encircling the upper arms and wrists are doubled, and circles form around the black dots on the shoulders. Sukuna's monstrous appearance led many to describe him as a demon with four arms and two faces.[1] In the past and present, Sukuna only wears a pair of pants, as his unique body prevents him from wearing clothes for the upper body.

Sukuna is selfish, cold-hearted, immoral, and exceptionally sadistic. When he was reincarnated shortly after Yuji ingested his finger, he commented, implying the slaughter of women and children and likening them to maggots crawling around. Due to his immense power, he rarely cares about the consequences of his actions, even if these affect his host, Yuji Itadori. In fact, he frequently taunts and insults Yuji, calling him a brat and even laughing at or enjoying Yuji's despair on multiple occasions.

Sukuna is aware of his immense power and is quite arrogant about it, brutalizing a finger bearer while being patronizing and proclaiming his superiority over it. For this reason, he is highly dismissive of his opponents and rarely takes them seriously, even explicitly stating he would kill Satoru Gojo to his face. However, these brutish traits are not to be confused for stupidity. Sukuna is highly intelligent and manipulative, taking Yuji's body hostage by tearing out his heart to force him into a binding vow.[5] He has also displayed the ability to acknowledge and praise his opponents, as shown by how before killing Jogo Sukuna acknowledged his strength despite having completely overpowered him and told Jogo that he should be proud.[6]

Through Sukuna's conversation with Yuji during their fight after possessing Megumi's body, Sukuna espouses that he likens human beings to insects and admits he is unable to comprehend why the weak cling so desperately to life instead of quietly accepting the suffering that life forces them to endure since the weak should have no right to complain. He also claims that he doesn't understand how a creature that falls apart at a touch can say that it always wants to be happy, which expresses his antipathy and disregard of human emotions and their will to live.[7] It also reveals that Sukuna's perception of life adheres strongly to social darwinism. It is also repeatedly stated that Sukuna has a myopic view on love and does not comprehend the value of relationships.[8]

Overall Skill Level: Back in the Golden Age of Jujutsu, the Heian Era, Ryomen Sukuna was feared and regarded by awe by all those in his time as the most powerful sorcerer of the time, defeating and killing thousands of jujutsu sorcerers even as they sharpened their skills against him. One of his feats included single-handedly slaughtering both the Sun, Moon, and Stars Squad and the Five Empty Generals, the most elite of the Fujiwara Clan's forces, leaving the authorities of Japan so utterly terrified that they were willing to hold festivities in his honor.[9][10] The impact Sukuna left on history until he died earned him the title of the "Strongest Sorcerer in History", as well as the "King of Curses". His strength is still held in such a high regard that even Satoru Gojo, the strongest jujutsu sorcerer of the modern age, with arrogance levels of confidence and pride in his abilities, acknowledged his strength and that a fight between the two of them would be difficult.

More than living up to his titles, Sukuna possesses vast amounts of cursed energy and equally incredible control over it, with an extraordinary grasp over jujutsu, but he was also not reliant on jujutsu alone, possessing overwhelming physical prowess as well, capable of dispatching almost any opponent without unveiling his true cursed technique.

Even at his weakest state upon his incarnation in Yuji's body for most of the time he spent there, due to lacking most of his fingers, Sukuna remained extremely strong, capable of effortlessly dispatching powerful cursed spirits, including the likes of a cursed spirit who had ate his finger, which he easily retrieved from the cursed spirit after completely overpowering it.[11] While purposefully weakening himself by removing Yuji's heart to ensure Yuji could not switch back with him, Sukuna utterly defeated Megumi Fushiguro, the inheritor of the Zenin Clan's prized Ten Shadows Technique and a prodigious genius who started school as a Grade 2 sorcerer with one of the highest potentials in Jujutsu High, to where Megumi admitted how utterly outmatched he was and was more than willing to unveil Mahoraga to defeat him. Sukuna would have killed Megumi had he not been interested in Megumi's unique talents, although before he could fight Megumi's trump card, Yuji managed to regain control of his body.[12]

Sought out by Mahito's group under the belief that his revival could ensure their success, with just three fingers, Sukuna demonstrated an overwhelming superiority in power compared to Mahito by being able to resist his Idle Transfiguration completely[13] and effortlessly inflict such a severe injury on Mahito when finally angered too much along with dispelling his Self-Embodiment of Perfection with a single attack.[14] This terrified and intrigued Mahito to where he came to firmly believe that with Sukuna being on such a whole other level, his resurrection would surely bring about the Age of Curses.[15]

Once Yuji's body had consumed fifteen fingers, Sukuna's overwhelming cursed energy was felt throughout Shibuya once he was awakened, compared to Satoru's own while being overwhelmingly more sinister.[16] With 75% of his strength restored, Sukuna proved capable of overwhelming Jogo, the most powerful cursed spirit in Mahito's group, in a mostly one-sided battle as he easily overpowered the best efforts of his foe, leaving him utterly unable to even land the single hit that would get Sukuna to join him, before killing him with his own speciality of fire.[17][18] His last act during the Shibuya Incident was to defeat Mahoraga single-handedly, a feat no user of the Ten Shadows Technique and even a member of the Gojo Clan with Limitless and the Six Eyes had done.[19]

Incarnation (受じゅ肉にく, Juniku?):[20] There is a slim chance that Sukuna will incarnate into whoever eats his fingers, gaining a physical, human body in the process. Upon Yuji consuming the first of his twenty fingers, Sukuna immediately came to possess his body, which he used to inhabit.[21] Unlike other incarnated sorcerers, according to the Angel inhabiting Hana Kurusu, Sukuna, after experiencing death, had developed the knowledge to split his soul as cursed objects,[22] which he demonstrated by imbuing all his cursed energy into Yuji's pinky finger and then force feeding Megumi with it to possess his body.

Master Hand-to-Hand Combatant: While immensely powerful as a jujutsu sorcerer, Sukuna is also shown to be an extremely skilled and powerful hand-to-hand combatant, using martial arts as his first method of combat before unleashing his jujutsu abilities. Sukuna can unite his cursed technique and his hand-to-hand prowess, making him an extremely difficult opponent to overwhelm in battle.

During his fight with Megumi, he was able to effortlessly overwhelm Megumi in unarmed combat, countering his attacks in close-range with ease before delivering a strong punch that send him flying. When Yuji attempted to attack him in his innate domain, Sukuna effortlessly countered all of Yuji's attacks before seeing through his attempt to trip him and defeating him with a single kick.[24]

With fifteen fingers, Sukuna easily overpowered Jogo with hand-to-hand combat alone before finally killing him with a single use of a cursed technique. He was later capable of fighting on par with both Yuji and Maki Zenin, both being exceptional unarmed fighters with extraordinary physical ability, deflecting most of their blows and landing a few hits on his own, using hand-to-hand combat.[25]

Immense Strength: In his first appearance, Sukuna was shown to possess immense physical strength despite being in an incomplete state. He could easily defeat a very large cursed spirit with just a simple swipe,[26] and during his fight against Gojo he was able to punch the roof of the school so hard it causes the building to rupture and crack.[27] He easily overpowered the likes of a Finger Bearer, a special-grade curse. When gambling Yuji's life against Megumi, Sukuna managed to fling the sorcerer through several building floors without effort and he easily overpowered and destroyed Megumi's shikigami.[28]He even punched Megumi so hard, the raindrops in that area dispersed. With fifteen of his fingers, Sukuna punched Jogo through buildings and even destroyed the latter's jaw.[29] His blows also had considerable effect on Mahoraga. Upon taking over Megumi's body, he was able to easily pierce through Yuji's gut and send him flying across the city with a single punch, stunning him temporarily.[30]

Immense Speed: Sukuna has repeatedly displayed overwhelming levels of raw physical speed, capable of effortlessly surprising most opponents with the sheer quickness of his movements. With three fingers, Sukuna easily slammed a Finger Bearer to the ground and even cut off its arm without it noticing. He was also able to effortlessly blitz Megumi several times, delivering powerful blows with Megumi barely able to react at all. With fifteen fingers, he easily overwhelmed Jogo and was able to keep up with Mahoraga in their fight. Sukuna was even able to instantly appear in the middle of Atsuya Kusakabe and Panda, both capable sorcerers, with the former being a Grade 1 sorcerer. In his fully incarnated form, he was able to outrun Yuji,[31] who could run at speeds of 60.12 km/h (37.3 mph).[32]

Immense Reflexes: Sukuna can easily counter any opponent and is fast enough for his opponent to not even realize that their limb has been cut off. He consistently dodged Mahoraga's blows and countered during their fight. He was quickly able to put Mahoraga down for good before he had finished regenerating. He was able to dodge Jogo's Maximum: Meteor.

Immense Durability: Even in Yuji's body, Sukuna can use cursed energy to bolster his host's resilience. Sukuna was punched through five buildings and shown to be completely fine.[33] Sukuna was able to survive a 200% Hollow Technique: Purple during his fight with Satoru Gojo by defending himself at the last second, losing only his hands.[34]

Great Tactical Intellect: Sukuna is an extremely intelligent individual. He has fully grasped the nature of cursed techniques, curses and reverse cursed technique as a whole. Due to that, he is able to quickly deduce the inner workings of cursed techniques after only seeing them once or twice and creating suitable foils to such techniques. He did this against Mahoraga in their fight, and was able to defeat the shikigami after gaining an understanding of its technique.

Sukuna was also able to realize the potential of Megumi's cursed technique just by seeing it once during their short battle and he was able to create a binding vow with Yuji in order to take Megumi's body patiently waiting for the right moment before executing his plan.[35] During his fight with Hana Kurusu, by using Megumi's memories he was able to make Hana think that Megumi was in control of his body and thus when she hugged him he was able to critically injure her.[36][37]

Metamorphosis: Sukuna can create new eyes and mouths on his host, allowing him to see and speak without controlling the body of the host. For example, he made a single eye and fanged mouth on Yuji's left cheek to belittle and taunt him.[38][39]

Immeasurable Cursed Energy: Sukuna possesses vast levels of cursed energy due to his innate power, cementing his title as the King of Curses. He was able to continuously use his techniques throughout his battles without exhausting himself in the slightest. His reserves of cursed energy likely is the most transcendent throughout history, far surpassing special grade cursed spirits and sorcerers alike. Yuta Okkotsu, a special grade sorcerer who possesses even more cursed energy than Satoru Gojo, states that Sukuna has double the amount of cursed energy that he has or more.[40] Sukuna also has absolute control over his cursed energy, being extremely proficient in both domain expansion and reverse cursed technique and capable of performing both flawlessly and repeatedly without issue. Hajime Kashimo, one of the strongest sorcerers from 400 years ago, was astonished by Sukuna's mastery over his cursed energy, displayed by his ability to seamlessly shift between domain amplification to his innate technique, to where he stated that if not for the Six Eyes, even Satoru Gojo would be no match against Sukuna in utilizing cursed energy.[41]

Black Flash (黒こく閃せん, Kokusen?): A phenomenon that occurs when the user applies cursed energy within 0.000001 seconds of a physical hit, creating a spatial distortion that causes their cursed energy to flash black and amplifies the destructive power of the strike to the power of 2.5. Sukuna first unleashed Black Flash against Maki Zenin during the jujutsu sorcerers' raid on him in Shinjuku, dealing a powerful strike that blasted away the girl with Heavenly Restriction.[42] Currently, Sukuna has used Black Flash a total of seven times.[43][44][45]

Unique Body Structure: In his true form, Sukuna possesses four arms and two mouths. The extra arms allow him to perform hand signs while keeping two of his hands free, and the extra mouth can continuously chant empowered words without straining his heart or lungs. These additional body parts provide him with an immense advantage over other jujutsu sorcerers, and despite its abnormality, his bodily functions are not impeded.[48]

Shrine : Sukuna's cursed technique allows him to launch slashes at various ranges to cut through objects and space, as well as unleash destructive flames.

Dismantle : Sukuna's default ranged slashing attack that can be used against cursed spirits and sorcerers to great effectiveness.[51] Using Mahoraga's second adaptation to Limitless as a model, Sukuna learned to enhance Dismantle by extending its target area to the world itself, transforming them into "slashes that cut the world"

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.[51] Unless used in his domain expansion, Sukuna must make physical contact with the target in order to activate Cleave.[53]

Spiderweb : Sukuna can utilize the Cleave technique in the shape of a spider's web by touching the ground. As a variation of Cleave, Spiderweb adjusts itself to the surroundings' toughness, collapsing the ground in one fell swoop.[54]

Divine Flame :[55] Sukuna can create and manipulate fire for long-range attacks by chanting "Open" [56][57] and forming an arrow. This technique can only be used after he performs Dismantle and Cleave.[58] The firepower of these flames exceed Jogo's, an unregistered special-grade curse whose defining trait involves extremely destructive pyrokinetic powers.

Reverse cursed technique is extremely complex and difficult for most jujutsu sorcerers to perform. One of the primary hurdles when using reverse cursed technique is compensating for blood loss from injuries. Reverse cursed technique can convert cursed energy into blood in a technical process that consumes a massive amount of cursed energy. Individuals who can already convert cursed energy into blood like the Death Painting Wombs can learn to use reverse cursed technique easier than others.[7]

Most reverse cursed technique users can only heal themselves. Healing oneself is more efficient and less difficult to perform than healing others.[8][9] One reason is the fundamental difference in application. Another is because the receiver's body can refuse the treatment due to an incompatibility with their cursed energy. The receiver could reject the healer's cursed energy or they could fail to respond to conversion. Due to this, the effectiveness of healing others with reverse cursed technique is case-by-case.[7]

Cursed spirits are manifestations of cursed energy and need only to manipulate it to heal instead of resorting to reverse cursed technique. They are vulnerable to positive energy because it can compromise the integrity of their bodies and destroy them.[10]

An innate technique exhausted by domain expansion cannot ordinarily be restored with reverse cursed technique. Satoru Gojo and Sukuna circumvented this limitation by damaging the engraving of their technique in their brain and then healing it with reverse cursed technique. However, they could not recover their exhausted technique and heal at the same time.[11][12] This is a highly risky maneuver that can leave lasting damage to the user's brain and even prevent them from using domain expansion altogether.

Domain Amplification : Envelops Sukuna in his own domain in the form of an aura around himself. Sukuna uses this technique to neutralize Gojo's Limitless technique and thus is capable of physical contact with him.[79] His finesse with domain amplification allows him to keep it active while using his domain expansion,[80] as well as use it in quick intervals to interrupt and resume Mahoraga's adaptation instead of nullifying its effect.[81]

Hollow Wicker Basket : An anti-domain technique that is the predecessor to Simple Domain. It erects a basket-shaped barrier that neutralizes a domain's barrier to nullify its guaranteed-hit factor.[82

Kamutoke : A powerful, vajra-like cursed tool that Sukuna wielded a thousand years ago, which is capable of discharging electricity. Yorozu crafted a replica for Sukuna to use in the modern age, through a binding vow just before she died.

Malevolent Shrine : is Sukuna's domain expansion using Shrine. Befitting its name, Malevolent Shrine constructs a disfeatured Buddhist shrine (vaguely resembling a chinjudō) that has been distorted to instead enshrine demons. Several bovine skulls form the base of the shrine. The roof has horns emerging from it, along with human skulls that hang down from it. The four entrances to the shrine are formed by four large, grotesque mouths, complete with humanlike teeth and tongues.[1][2] Another smaller mouth is present between the two layers of the roof. Four short, disfigured tree-like stumps with gnarled branches stand at each corner of the shrine.In its alternate form, Malevolent Shrine takes a much more gruesome and beastly appearance. It takes the form of a large mass of flesh, horns and teeth with multiple large eyes that stare in different directions. There are also patches of hair-like appendages throughout its body, along with four large curved horns at the top, two giant humanoid hands at the bottom and a spine-like appendage tapering down from the back.Malevolent Shrine's guaranteed-hit ability relentlessly slashes apart anything until nothing but dust remains of what has been caught in the effective range, via Sukuna's two types of slashing attacks: Cleave and Dismantle, which only cease when the domain is disengaged or Sukuna is so badly injured he can not sustain the domain anymore. Sukuna can set which of the two attacks to use against specific types of targets, such as using Dismantle for inanimate objects and Cleave for subjects with cursed energy.[3]

Sukuna has the divine ability to expand his domain without closing the barrier to create a separate space. This creates a binding vow due to allowing an escape route from the domain that enables him to expand the effective range of the guaranteed-hit up to a maximum radius of nearly 200 meters. Furthermore, unlike other domains which operate with an outer shell like Unlimited Void and can be cancelled if the shell is destroyed, Malevolent Shrine cannot be destroyed by any normal means because of the lack of an enclosed barrier. The only way to effectively destroy Malevolent Shrine is to injure Sukuna to the point where he can no longer maintain the domain.[4][5]
