If trained by Kami in a fanfic, Naruto's character would evolve into a more balanced one. He has always been full of energy and determination, but Kami's training could add a layer of calmness and wisdom to him. He would start to think more before acting, weighing the consequences of his actions. His relationships with others would also change. He would be seen as more of a sage - like figure, and people would look up to him not just for his strength but also for his new - found wisdom. This would also affect his relationships with his friends and enemies alike. For instance, his enemies might start to fear him not just because of his power but also because of his unpredictable and wiser moves.

If trained by Hashirama in a fanfic, Naruto's character would grow in several ways. Firstly, his confidence would be enhanced in a different way. Instead of relying solely on his own tenacity and the power of the Nine - Tails, he would have the knowledge and skills passed down from one of the most legendary shinobi. This would give him a new sense of self - assurance. Secondly, his sense of responsibility towards the village would expand. Hashirama founded Konoha, and Naruto would understand more about the roots and values of the village, thus becoming more committed to its long - term well - being. He would also be more open - minded, as Hashirama had a very inclusive view of the ninja world, and Naruto would adopt some of that perspective.
