In such a fanfiction, Naruto might use his scientific knowledge to improve Konoha. He could develop new jutsu based on scientific principles, for example, creating more efficient ways of using chakra. Maybe he'd study the biology of the tailed beasts to find better ways to co - exist with them.
If Naruto becomes a scientist in fanfiction, he would likely focus on areas that could benefit his friends and village. He could invent new forms of defense mechanisms for Konoha. Since he has always been about unity, he might also research ways to use science to bridge the gaps between different ninja clans and promote better understanding among them.
Well, Naruto as a scientist in fanfiction would be quite an interesting concept. He'd probably start by studying the history of ninja techniques and try to find scientific explanations for them. This could lead to a revolution in the ninja world as old techniques could be refined or new ones created. He might also collaborate with other intelligent characters in the Naruto universe, like Shikamaru, to come up with brilliant scientific ideas that could change the future of their world for the better.
