Satoru Gojo

Intro Overall Skill Level: Even among the special grade sorcerers, Satoru is known to be the strongest, holding both immense amounts of cursed energy and a dangerously powerful technique. No one can seemingly match his skill level except for the King of Curses, Sukuna. As students, Satoru and Suguru were considered "the strongest," capable of quickly dealing with experienced and powerful curse users. Whereas before, he and Geto were no match for the renowned Sorcerer Killer, 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 after realizing and perfecting his capabilities. As he continued growing, he eclipsed Suguru's talents to the point Saguru admitted Satoru to be the strongest alone. Suguru also stated that Satoru had the capability of killing all of humanity by himself, which Suguru admitted was out of his ability and didn't even try to fight back when Satoru prepared to kill him, although Satoru ultimately relented as he was unable to kill his best friend.
