In this fanfic, Naruto would develop a more refined sense of strategy. Yen Sid's wisdom would rub off on him, and he'd start to think several steps ahead in combat. His relationships with his friends might also change. He could become more of a mentor figure to them, sharing the new knowledge he's gained from Yen Sid. Naruto would also become more in tune with his spiritual side. Learning from Yen Sid, who is likely very attuned to spiritual matters, Naruto would start to explore the deeper meaning of his own ninja way and how it relates to the broader universe.
Naruto's character would develop in several ways. Firstly, his sense of discipline would improve. Yen Sid is a strict teacher, and Naruto would have to follow a strict regimen. This would make him more reliable and less impulsive. Secondly, his understanding of different cultures and powers would grow. Interacting with Yen Sid and his world would expose Naruto to new ways of thinking and being. He'd become more open - minded and adaptable, which are important traits for a hero. And finally, his confidence would be on a different level. Mastering new skills under Yen Sid's tutelage would make him feel more capable of handling any situation.
Well, it could be that Naruto is transported to Yen Sid's world. Yen Sid, with his great magical knowledge, teaches Naruto new forms of chakra control that are more in line with magic. Naruto might learn to use his shadow clones in more strategic and magical ways, like creating clones that can perform spells independently.
Naruto's character would likely become more reserved and stealthy. He'd be used to operating in the shadows, which is a big change from his normally boisterous self. His sense of justice might also be refined, as the ANBU has a different view on protecting the village.
Naruto's character could become more calculating. Since Jango is a more cold - calculated fighter, Naruto might start to think more before acting. He could become less impulsive in battles.
He might gain a different perspective on strength. Naruto is used to relying on his ninja techniques and the power of the Nine - Tails. But with Zoro's training, he would understand the value of pure physical strength and swordsmanship, which could make him a more versatile fighter.
Naruto's character would become more worldly. He'd be less naive about the different ways of life. His sense of justice might expand to include the pirate way of life as well. He'd also become more confident in his abilities as he masters new skills under Whitebeard.
Naruto would become more disciplined. Sarutobi is a strict teacher, so Naruto would have to follow rules more closely. This would make him less impulsive in battle.
Naruto's character could become more focused and disciplined. Ryu's training might instill in him a sense of precision that he didn't have before. For example, Naruto is often impulsive in battles, but with Ryu's influence, he could learn to calculate his moves more carefully.
Naruto's character might become more calculating. Kisame is a very strategic fighter, and Naruto could pick up on this trait. He would start to think more before acting in battles.
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.
His character would grow in terms of maturity. Facing the challenges of Whis' training, Naruto would gain a deeper understanding of his own power and limitations. He would also become more humble as he realizes how much more there is to learn in the wider multiverse. Moreover, his sense of responsibility would expand as he aims to use his new - found abilities for the greater good not just in his own ninja world but potentially across different realms.
