King of Curses

Summary: Ryomen Sukuna is Heian Era sorcerer, he was once known notoriously as the King of Curses and legended as the greatest jujutsu sorcerer to ever live before actually becoming a curse himself. Sukuna is selfish, cold-hearted, arrogant, immoral, sadistic, highly intelligent, and manipulative. He has 4 arms, 4 eyes, pink hair, red eyes, a huge mouth at his torso, and curse markings all over his muscular body. He is skilled at hand to hand combat and cursed energy manipulation.

Appearance: Sukuna's true body is that of a tall, muscular man with four arms, four eyes, and a large mouth on his midriff. He has short pink-red hair and red eyes. His two right eyes are angled differently and located on a white plate-like structure made of flesh on the right side of his face. His body is 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, ankles, upper arms, upper body, abdomen, and face. Large 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. The vessels also gain a horizontal line on the bridge of the nose, and a crown-like symbol in the middle of their forehead. Sukuna's monstrous appearance led many to describe him as a demon with four arms and two faces, although he was a mutant curse user rather than a cursed spirit. In his true body, Sukuna most often wears only a pair of pants, as his unique torso is difficult to clothe.

Personality: Sukuna is egocentric, hedonistic, psychopathic, exceptionally sadistic and selfish. Mass murder, suffering, and the screams of his victims are what the King of Curses relishes; this is best shown when he was reincarnated shortly after Yuji ingested his finger, after which 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. In fact, he frequently taunts and insults Yuji, calling him a brat and even laughing at or enjoying Yuji's despair on multiple occasions. Outwardly, Sukuna claims to have no dreams, goals, or aspirations to work towards, while the jujutsu sorcerers fighting him do and grow stronger because of it. However, on one occasion, Sukuna has alluded to feelings of resentment from his upbringing. Sukuna is an immense glutton, not only for actual food and human flesh, but for fighting and bloodshed. Because of this, he tends to draw out his fights with strong opponents even if it would be wise to finish up his fights quickly. Sukuna is aware of his immense power and is 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. While in possession of Fushiguro's body, he fooled Hana Kurusu into lowering her guard by pretending his influence was removed from the boy. He has also displayed the ability to acknowledge and praise his opponents on multiple occasions. Primarily seen before his killing of Jogo, Sukuna acknowledged his strength despite having completely overpowered him and told Jogo that he should be proud. In rare cases, Sukuna is capable of forming non-combative relationships, as he had taken in a young Uraume initially to have the child cool his food chilled and cook for him and eventually to be his subordinate. While he is observative when it comes to jujutsu, he's displayed a lack of interest in the modern world's technologies and foods, glancing at Nanako Hasaba's smart phone used for her technique and refers to it as a phone with a camera, showing that he doesn't pay attention to the modern age aside from jujutsu. 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. Sukuna's perception of life adheres strongly to social darwinism. It is repeatedly stated that Sukuna has a myopic view on love and does not fully comprehend the value of relationships. Though he claims to understand love, Sukuna considers it worthless and abhors the idea of needing another individual to satisfy him. According to the King of Curses, responding in kind to the multitude of sorcerers who sharpened their skills and rose to kill him is his way of connection. Stemming from this mindset, Sukuna is enraged by anyone pitying him or offering him mercy, as he bases his identity on being the strongest and views such acts as considering him weak. However Sukuna's perception of life is rooted in some hypocrisy, as he was willing to further demoralize Fushiguro's faltering will in an openly desperate attempt to live. Yuji's existence affects Sukuna in a way he can't ignore, no matter his efforts. Due to the nature of his initial incarnation within Yuji, Sukuna is unable to disregard how Yuji himself challenges his worldview by being Sukuna's opposite and invalidating his views. Furthermore, this fills Sukuna with a hatred that he can't describe, unlike anything he has ever felt. His constant belittlement of Yuji and refusal to consider him a threat in spite of knowing that Yuji is the grandson of Sukuna's reincarnated twin brother exemplifies this. This is compounded when Yuji offers Sukuna one last chance to surrender out of mercy and Sukuna is enraged by the pity Yuji shows him. Even on the verge of death, Sukuna could only bring himself to compliment Yuji's attempts at leveling with him as a long standing farce, refusing to accept mercy. Despite his immense arrogance Sukuna had while alive, in death Sukuna is capable of introspection. In the passageway for souls in circulation, Sukuna did not deny Mahito's accusations of lying to himself about his own nature of wanting revenge against those who scorned him in the past. Sukuna even confessed that had he not feared immolation from his own curse, he would have been able to go down less destructive paths. He even appeared to be open to changing his ways should he reincarnate and accepted his loss.

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. 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.
