Sukuna is arrogant, sadistic, and purely hedonistic. He operates entirely on the philosophy of "might makes right," believing that he is a god among mortals and caring only for combat and eating. Because he values only raw power, he is completely incapable of understanding selfless behavior or human love. He is widely considered the strongest foe globally. His vast reserves of cursed energy allow him to use advanced Reverse Cursed Technique to heal himself and others instantly. His signature cursed techniques allow him to slice his opponents with precision, while his Domain Expansion, Malevolent Shrine, creates an inescapable killing radius that shreds everything inside it. Looks like a terrifying, muscular figure possessing four arms, two mouths, and four eyes (with two smaller ones situated on a mask-like plate on the right side of his face). He is heavily covered in distinct, black "Marks of Enlightenment" tattoos across his face and torso.

His Domain Expansion creates a supernatural courtroom where he acts as the prosecutor and a shikigami named "Judgeman" acts as the judge. It enforces a strict, no-lie trial. This shikigami evaluates evidence to hand down verdicts. Depending on the ruling, the domain can temporarily strip an opponent of their cursed energy or even deliver the "Executioner's Sword"—an instakill blade. He appears as a tall lean lawyer man who hasn't seen rest.

The strongest jujutsu sorcerer outside of Satoru Gojo and Ryomen Sukuna. He has a copy technique and the ability to summon a shikigami named Rika who loves him very much. He carries a blade and has access to his own domain expansion. Having a ton of cursed energy and appearing like a sleep deprived teen.

An insane physical beast of a guy who can use blood manipulation, soul piercing attacks, and punches really damn hard. He's related to Sukuna thanks to Sukuna's twin reincarnation as his gramps. He has a strong moral justice and seeks revenge on Sukuna after all he's suffered.

The slaughterer of the Zenin clan, and a woman with no cursed energy. Being an insane physical fighter who uses a blade that damages the soul.

The strongest grade 1 sorcerer who was put in the ring due to lack of fighters. He is a master of the basic techniques and some complex ones. He doesnt have a cursed technique at all. Appearing as a man with a coat and exceptional skill with a blade.

Yuji itadori's loyal brother by blood, he uses blood manipulation to create shields, or fire off sharp piercing blood beams to injure and poison enemies. Appearing as an attractive man with a marking stretching on his nose to his cheeks.
