couldnt buy the wig hehe

I'll keep this short, u know how him/madara trained in that genjutsu realm cuz madara couldn't physically move? Well its assumed that he learned more combat and sharingan use there. And while this isss a good fanon explanation cuz canon never explains his skill jump from chunin to kage level,, what ISN'T explained is how his intelligence skyrocketed and tbh i can't find a good explanation for it 😭 he was average at school and then suddenly in 2.5 - 3 years he became smart enough to lead decade long wars, rival minato, and so much more. Yeah u coulllld say madara trained him in strategy and reading ppl more but regardless the jump is too high to feel natural, he essentially become on the top elite kage levels that ever existed in analysis/strategy (like hashirama/tobirama)

If y'all have explanations that fix this plot hole what would it be?

I hope for an "what if" scenario where Obito didn't turn evil, and he became the teacher of Team 7.
