Gojo Satoru and Geto Suguru

Geto Suguru: Geto Suguru was a promising and talented jujutsu sorcerer. Here are the key aspects of his character and life before his shift:

Student at Tokyo Jujutsu High: Geto was a student at Tokyo Jujutsu High, one of the premier institutions for training jujutsu sorcerers. He was in the same class as Satoru Gojo, and the two were considered the top students of their time.

Friendship with Satoru Gojo: Geto and Gojo shared a close friendship during their time as students. They often worked together on missions and had a strong bond. Their complementary abilities made them a formidable team.

Idealistic and Caring: Initially, Geto was driven by a strong sense of duty and responsibility to protect non-sorcerers from curses. He believed in the mission of the jujutsu sorcerers and was committed to his role as a protector.

Talented Sorcerer: Geto possessed exceptional talent as a jujutsu sorcerer. His unique ability to manipulate and control curses made him one of the most powerful and promising students at the academy.

As a Jujutsu high student, Geto displayed kindness and respectable qualities. He usually stood out in his pairing with Satoru Gojo as the most responsible of the two. Despite this, Gojo and Geto always had high regard for one another and considered each other as best friends. Due to how skilled they were with their techniques, they considered themselves 'the strongest'. Suguru was capable of making short work of experienced curse users on multiple occasions with little effort. His collection of cursed spirits was wide with a high variety of different abilities and roles in battle. Suguru was not overly dependent on his curses and was a highly capable close-quarters fighter as well.

Great Tactical Intellect: Suguru Geto was always a brilliant student at Jujutsu High. While Satoru would forget key points about Master Tengen and other detailed aspects of their missions, Suguru would be the one to remember and explain things to him. His intellect translated well to battle, always able to think a step ahead of his opponent. An older and more experienced curse user attempted to outmaneuver the curse manipulator into getting closer, only to fall into Suguru's trap.

In his fight with Toji Fushiguro, Suguru managed to surprise the Sorcerer Killer for just a moment. He moved behind Toji knowing his confidence would keep his guard down and nearly absorbed the inventory curse as a means to cut off Toji's weapons supply. However, this ultimately backfired due to circumstances Suguru could not have foreseen, leaving him open to getting exploited at close range.

Cursed Energy Manipulation: Due to the nature of his technique, Suguru Geto's cursed energy feels slightly different from other sorcerers. He has a high understanding of how cursed energy and techniques generally work. Suguru is capable of manipulating it to hide his residuals or imbuing energy it into weapons among other applications. He's also able to read the flow of cursed energy of other sorcerers without any difficulty. Suguru is famous for being able to manipulate thousands of curses at the same time with high reserves of cursed energy.

Cursed Spirit Manipulation: As the name implies, Suguru's innate technique allows him to control vagabond cursed spirits. Dominated curses are absorbed into small black orbs that Suguru must ingest orally in order to use. If the difference in grade is more than two levels, Suguru can absorb a curse with no consequences. He's also able to absorb other sorcerer's curses as long as he kills the master first.

Gojo Satoru:

Satoru is a very tall, lean and muscular man who is in his late twenties and is considered relatively attractive, mainly due to his facial features. He has snow-white hair and the Six Eyes, which are a vibrant blue color. Satoru normally covers his eyes with a black blindfold which props up his hair and gives it a spikier appearance. When sporting a more casual look, Satoru will wear sunglasses and let his hair down to reach the base of his neck.

While working, Satoru wears a dark blue zip-up jacket with a high collar that's also fairly wide. He wears slim-fit matching black pants and black dress boots. Before switching over to a simple blindfold, Satoru used to wear bandages over his eyes. Satoru enjoys wearing expensive clothing and has a number of casual looks he'll pair with wearing his sunglasses. As a Tokyo Jujutsu High student, Satoru wore the normal school uniform with his sunglasses before adopting any sort of makeshift blindfold.

Satoru is a complex individual. He is normally seen to be nonchalant and playful towards his students, close colleagues, and friends. However, he is unsympathetic and cruel towards sorcerer executives, an example being his blatant disrespect towards Principal Gakuganji, and his enemies.

Satoru is extremely confident in his abilities and reputation as a powerful sorcerer, believing himself to be invincible. His opinion of others often only go as far as his judgement of their strength, and he is quite apathetic towards anyone he deems weak. Additionally, greatly influenced by his own desire for power, he is very arrogant. He is convinced that he is the strongest in the world, which he technically is, claiming, during his fight with Toji Fushiguro, that "Throughout the Heavens and earth, he alone is the honored one." This can be further exemplified when he was tasked with protecting Riko Amanai, one of the few 'weak' people he genuinely grew to show compassion for. However, any empathy of her death was soon negated by his extensive amount of pride and arrogance after perfecting his reverse cursed technique in his following battle against Toji Fushiguro.

During intense battles, Satoru is seen to occasionally fall into a frenzied fighting state, urged by his determination for victory and undeniable proof that he alone is the strongest. His combative style is characterized by his aggressive and domineering attacks, while flaunting his mastered techniques to his opponents. Furthermore, in a crisis, he is capable of being cold-blooded. He will prioritize his enemies' destruction over saving innocent people when he believes that the sacrifice is unavoidable. However, this only extends to the people killed by his opponent; he will not do any lasting harm to or kill anyone innocent to gain the upper hand.

Nevertheless, despite his haughtiness and strength, Satoru is more human than he first appears. After defeating Toji, Satoru retrieved Riko's corpse with a sorrowful look, showing that albeit his recent conceited victory temporarily clouding his feelings, he still felt some grief over her death. He sought to kill the Star Religious Group members that were laughing over Riko's death, though was stopped by Suguru Geto — who he relied on as a moral compass at that time — before taking any action. He was also distraught when Yuji seemingly died.

Satoru's endgame is to reform the jujutsu world from the bottom-up through education. He seeks to foster a new generation of sorcerers that he hopes will one day become his equals.

Overall Skill Level: Even among the special grade sorcerers, Satoru is known to be the strongest sorcerer in the series, holding both immense amounts of cursed energy and a dangerously powerful technique. No one can seemingly match his skill level in the current storyline, except for the King of Curses, Sukuna.

As a student, Satoru and Suguru were both considered "the strongest", capable of making short work of experienced and powerful curse users. After realizing and perfecting his capabilities, Satoru's abilities vastly increased to where he was able to put Toji Fushiguro into the defensive and ultimately kill him with his strongest technique, whereas before he and Geto were no match for the renowned Sorcerer Killer.

In the present, Satoru's might was feared by the higher-ups of the jujutsu society, to where Satoru could easily force them to cancel the executions of the likes of the dangerous fellow special-grade sorcerer Yuta Okkotsu and the vessel of Sukuna Yuji Itadori and he states that it would be easy for him to kill them all and overthrow the jujutsu society had he actually wanted to. Satoru even claimed that he could defeat Sukuna at his full power.

Master Hand-to-Hand Combatant: Satoru, in addition to his overwhelming levels of cursed energy, is also an extremely formidable martial artist in close combat, with extraordinary physical prowess to back up his skills. Q&A with Gege Akutami revealed that Satoru is as skilled as the millennia-old Kenjaku in terms of pure hand-to-hand combat without any cursed energy. He was capable of completely overpowering Jogo in hand-to-hand combat, delivering several precise attacks on Jogo's fatal spots, and could even casually fight off and overpower both Jogo and Hanami with sheer close combat, easily countering their attacks and landing powerful hits that swiftly pummeled them into submission.

Immense Strength: Satoru has extraordinary physical strength to fight against powerful curses without a problem, easily causing severe injuries to Jogo with powerful punches and throwing him a considerable distance with a single kick during their fight. He was also able to easily rip out Jogo's head and later on his arm with sheer physical force and even managed to casually rip out Hanami's roots. He could casually rip apart transfigured humans, tearing them apart limb-by-limb.

Immense Speed & Reflexes: Satoru is an extremely fast fighter, capable of moving faster than the eye could perceive. He managed to easily outpace Jogo, throwing almost imperceptible punches and kicks. Satoru was even able to successfully react to and dodge the attacks of someone of Toji Fushiguro's level. Satoru can also eliminate a thousand transfigured humans in five minutes.

Immense Endurance: Despite rarely being put in dangerous situations, Satoru has proven himself to be overwhelmingly resilient when needed to be. When Toji Fushiguro stabbed him through the chest when he had just deactivated his Infinity, Satoru showed little pain and with cursed-energy reinforcement, he was able to avoid any further damage. Even after being impaled on the throat and then savagely slashed through his body, not only did Satoru survive, but he was able to instead use the life-and-death experience to understand the nature of Reverse Cursed Technique and become even more powerful than he ever was.

Great Tactical Intellect: Satoru is quite tactical and capable of figuring out his opponent's plan with minimum information. He has also shown to be extremely adaptable to any enemy he has ever faced so far, knowing precisely what to do to counter their techniques and find ways to defeat them. This is best displayed during his bout against Jogo, Hanami, Choso and Mahito where he was shown to be capable of conceiving multiple battle strategies while fighting at blinding speeds, protecting civilians, keeping property damage to a minimum, all while dodging and evading the attacks of the four curses.

Immeasurable Cursed Energy: Satoru Gojo is known within the jujutsu society as the strongest jujutsu sorcerer in the world. He earned this alias due to the immense amounts of cursed energy he possesses. His cursed energy is vast enough to use a Domain Expansion at least five times in one day, while most sorcerers can only use it once.

Gojo has excellent control over his cursed energy, capable of activating his Domain in a split second, use reverse cursed technique, and even combines positive and negative cursed energy. Gojo is also known to have two overarching abilities, being the first in four hundred years to have both the Six Eyes and the Gojo family's Limitless cursed technique.

Black Flash (黒こく閃せん Kokusen?): A technique that creates spatial distortion when a user connects with an impact of cursed energy within 0.000001 seconds of a physical hit. The phenomenon causes cursed power to flash black, creating a more potent attack to the power of 2.5 of a normal hit. He managed to use Black Flash against Sukuna during their battle in Shinjuku, dealing a devastating strike when the King of Curses least expected it. It is currently unknown how many times exactly Gojo has performed Black Flash, but he has used it at least four times.

Limitless (無む下か限げん Mukagen?): At the base level, Limitless is an innate technique which is derived from the Gojo family. This technique grants its users nigh-absolute control over space through cursed energy manipulation at an atomic level, resulting in multiple subsequent results and techniques within the overall ability. With the manipulation of space as just the base level of the technique, Limitless has three standard and one "non-standard" form beyond this.

Infinity (無む限げん Mugen?): Being the neutral form of the Limitless, the Infinity is commonly known as the ability to stop, although this is a common misconception as the true power of the Infinity is to slow things down. When something attempts to hit Satoru, the person or object in question instead hits the infinity between himself and them. According to Satoru, this is the convergence of an infinite series and comes straight from the paradox of Achilles and the tortoise. Akin to the way Achilles will never catch the tortoise due to the potential, infinite amounts of finite space separating them or how the real number one will never touch the real number two due to the infinite amount of fractions that separate them, the opponent will never touch Satoru due to the infinity between them. Satoru can decide what does and doesn't touch him and can do so based upon mass, speed, and danger ratings.

Cursed Technique Lapse: Blue (術じゅつ式しき順じゅん転てん「蒼あお」 Jutsushiki Junten・Ao?): The reinforced version of the neutral limitless; Blue is the byproduct of Gojo amplifying the Limitless and negative energy, producing a vacuum. Through these, Gojo creates a scenario where the world itself is forced to correct itself and fill in the negative space, causing all matter in the range of the commanded space to be pulled together.

Cursed Technique Lapse - Maximum Cursed Energy Output: Blue (術じゅつ式しき順じゅん転てん出しゅつ力りょく最さい大だい「蒼あお」 Jutsushiki Junten Shutsuryoku Saidai・Ao?): Satoru creates a center of gravity in a specific space capable of attracting all matter, crushing it all effortlessly akin to a black hole. He can also move the point of gravity at will, augmenting its destructive capabilities greatly.

Cursed Technique Reversal: Red (術じゅつ式しき反はん転てん「赫あか」 Jutsushiki Hanten・Aka?): Being an inversion of Blue, Red has the opposite effect. Using his reversal technique to invert the properties of Blue, Satoru activates the divergence of his infinity and causes an extremely powerful repulsive force, repelling all matter in its vicinity. Being an ability that is powered by positive cursed energy and formed as a reverse curse technique, the ability has two times the destructive ability of Blue.

Hollow Technique: Purple (虚きょ式しき「茈むらさき」 Kyoshiki・Murasaki?): An advanced technique that collides the Lapse and Reversal of the Limitless, resulting in an imaginary mass that is launched at the target.

Reverse Cursed Technique (反はん転てん術じゅつ式しき Hanten Jutsushiki?): At first, while a first and second year student of Jujutsu High, Satoru was unable to grasp the complex nature of reverse cursed technique, but after being put on his deathbed during his first fight with Toji Fushiguro, Satoru, tapping into the core of cursed energy, was finally able to unlock the ability to not only heal himself, but also make the positive energy flow into the Infinity, giving him access to his Red and Hollow Purple attacks.

While he has yet to master the skill of healing others, which is something that few like Sukuna and Shoko can do, by the time he became a third year student, Satoru had mastered reverse cursed technique to the point where he developed the unprecedented ability to keep a reverse cursed technique flowing through his body constantly as to keep his brain fresh despite making constant use of the Six Eyes and the Limitless at a scale that would normally fry his brains, which also served to heal him should any attack pierce his Infinity.
