Since its beginning, Jujutsu Kaisen has been explicit in its uniqueness from other anime. From character design and abilities to story progression, it brings perspectives quite new to the shonen genre. Early on, the series' introduction of its most powerful character, Satoru Gojo, was also different.
Satoru’s abilities cannot be overstated. He’s widely known as the most powerful jujutsu sorcerer in the series -- not just currently, but of all time. His mere existence is a deterrent to villains and until he is neutralized, their long-term plans are on hold. Barriers are specifically designed to prevent Satoru from entering any space they’re operating in and when he inevitably breaks them, their only option is to retreat as a one-on-one battle would be suicide. But what exactly makes Satoru so powerful?
The answer lies in his extraordinary control over cursed energy and two techniques he inherited from the unusually powerful Gojo clan: Limitless and Six Eyes. Limitless technique users are granted almost total control over space. This level of control allows Satoru to create an infinity barrier between himself and an opponent. Any attacks launched against him never make contact but crash into his barrier instead. Satoru can choose what does and does not touch him, but that’s just the tip of the Limitless iceberg.
“Cursed Technique Lapse: Blue” allows Satoru to create a vacuum wherever he chooses, drawing every object or person in the vicinity toward it to be crushed if he wishes. “Cursed Technique Reversal: Red” has the opposite effect of Blue and is even more powerful. It creates an extremely powerful center of repelling energy that pushes any person or object away with extreme force. Activating those two techniques at the same time creates the “Hollow Purple,” a giant ball of pure destruction that instantly disintegrates any matter it comes into contact with. Satoru is able to pull off every one of these techniques with no difficulty.
Six Eyes is another special jujutsu technique passed down within the Gojo clan. Only sorcerers with Six Eyes can use the full potential of Limitless, but the ability does not manifest regularly. In fact, in the last 100 years of the manga timeline, Satoru has been the only person to unlock both abilities, which would explain why there aren’t other equally powerful members of his clan showing up.
Six Eyes grants Satoru absolute vision. He has the ability to see across vast distances and through any obstacles. His eyes are able to analyze cursed techniques so he can instantly figure out the best way to counter them. Six Eyes also allows Satoru to use the minimum amount of cursed energy required to activate any technique. This, coupled with his already large reserves of cursed energy, means it’s almost impossible for him to deplete his energy stores in a fight.
Satoru keeps his eyes hidden to prevent being overwhelmed by the constant barrage of visual information. When he’s dealing with a low-level opponent or not fighting, his Six Eyes are obscured by dark shades or a blindfold which he has no problem seeing through. Satoru’s cursed energy regulation ability means he can also use his Domain Expansion, “Infinite Void” as many times as he wishes. It forces anyone caught within to receive an overwhelming amount of stimuli across all their senses, rendering them immobile. The limit to regular sorcerers and cursed spirits is once a day.
Limitless and Six Eyes already make Satoru Gojo more powerful than any regular sorcerer in Jujutsu Kaisen, but his immense physical strength also makes it possible to go toe to toe with even special grade cursed spirits, blasting them away with casual punches and kicks. Combined with his years of experience and tactical expertise, Satoru's inherited techniques and strength easily make him the most powerful jujutsu sorcerer.
