You know, a lot gets made of how powerful he was from the start, and it's true, the Six Eyes and Limitless made him a monster. But I think the real struggle for young Gojo was never about raw strength—it was about connection. He grew up isolated in the Gojo clan, treated more like a living artifact than a kid. Everyone feared him or wanted to use him. That's a weird kind of loneliness, right? He couldn't even have a normal conversation without his cursed energy intimidating people.
His early days at Jujutsu Tech probably reinforced that. Sure, he had Geto, but even that friendship was built on being the only two at that insane power level. The challenge was learning to be human, not just a god. He had to figure out how to care about the weak without looking down on them, which he clearly struggled with before Geto's betrayal. The hidden inventory arc is basically a thesis on that. The ultimate test wasn't a fight; it was watching his one true equal walk away into the darkness, and realizing strength alone couldn't fix anything.
That's the core of it for me. His biggest battles were internal, about purpose and responsibility, long before he had to seal Sukuna or anything.
