Gojo is the strongest, but these characters have, at the very least, the potential to match him someday in JJK.
Gojo Satoru was certainly one of the most powerful sorcerers in all of JJK, and fans know him to be a monster in combat. He could only be rivaled by Ryomen Sukuna, the King of Curses, and together, these two were a cut above the rest. When it comes to Gojo specifically, fans know that he had mastered the Limitless Cursed Technique, and coupled with the Six Eyes, he was essentially untouchable.
Gojo was a genius right from birth, but that certainly doesn’t mean that he did not work hard. His limitless talent was brought to the surface through rigorous hard work, and, in many ways, he was a blend of talent and hardwork. Still, when it comes to his talent, fans know that hardly anyone was as gifted as him in JJK. That said, there are a select few individuals in JJK who are said to hold a similar level of potential to Gojo, and could reach a level similar to him in their primes.
Megumi Fushiguro
Megumi is one of the main characters in JJK. He was always a friendly rival to Yuji Itadori, but more than that, Megumi was an individual that Gojo believed would reach tremendous heights. In fact, Gojo himself implied that Megumi, who is the current user of the 10 Shadows Inherited Technique, could one day reach his level.
Gojo implied this directly when he mentioned that a former head of the Zenin Family and a former head of the Gojo Family ended up killing each other due to being on a similar level of strength. These individuals held the 10 Shadows Technique and the Six Eyes and Limitless technique respectively. This was essentially Gojo’s way of saying that Megumi could one day reach his level of strength. Even though Megumi was cut out from a significant portion of the series, having Sukuna fight in his body most likely gave him muscle memory of his combat style.
