Sukuna Ryomen

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. 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.

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. 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.

Immense Strength: In his first appearance Sukuna has 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, 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. 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. His blows 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.

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.

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.

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.[4] Sukuna was able to survive a 200% Hollow Technique: Purple during his fight with Satoru Gojo.

Great Tactical Intellect: Sukuna is an extremely intelligent individual. He has fully grasped the nature of cursed techniques, and curses and reverse cursed energy 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. During his fight with Hana Kurusu by using Megumi's memories he was able to make Hana think that Megumi is in control of his body and thus when she hugged him he was able to critically injure her.

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.

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.[5] 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 hundred 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

His powers and abilities are: Incredible Amounts of Cursed Energy, Domain amplification, Cleave, Dismantle, Fire arrow, Reverse cursed technique, Domain expansion - Malevolent shrine: Sukuna's Domain Expansion creates a Buddhist shrine decorated with skulls. Malevolent Shrine has a unique trait; it doesn't create a separate space using a barrier.
