Naruto's character would likely become more complex. Danzo's training methods are strict and often involve a certain ruthlessness. Naruto, used to more open - minded and friendly training from the likes of Jiraiya, would have to adapt. He might become more calculating and less impulsive, which could be both good and bad. Good in that he'd be a more strategic fighter, but bad in that he might lose some of his charm and spontaneity that his friends love him for.
Naruto's character development would take an interesting turn. With Danzo's training, Naruto could gain a new sense of discipline. He would learn to control his emotions better, which is something Danzo would surely enforce. However, he might also inherit some of Danzo's paranoia. Since Danzo was always suspicious of others, Naruto could start to view the world with a bit more distrust. But at the same time, he could also use this new perspective to better protect the village. He might develop new ninjutsu skills that are more in line with Danzo's combat style, which would set him apart from his previous self and make him a more well - rounded shinobi.
The training could make Naruto more self - reliant. Danzo would probably push Naruto to rely on his own skills rather than always depending on his friends or the power of the Nine - Tails. This could lead to Naruto developing new techniques and strategies on his own. He'd grow as a ninja in a way that's different from his growth under other mentors, like Kakashi or Jiraiya. His confidence would also come from his own achievements in training rather than just his natural abilities.
Well, it could be that Danzo trains Naruto in some ancient and forbidden jutsu. Naruto, being the curious and determined character he is, is intrigued by these new powers. However, he soon discovers that these jutsu come with a price. He has to struggle with the moral implications of using such powerful and potentially dangerous techniques while also trying to keep his identity as a jinchuriki a secret. This would create a lot of internal conflict for Naruto and also change his relationship with Danzo throughout the fanfic.
The training could also make Naruto more disciplined. Minato and Kushina were both highly disciplined ninjas. Their training methods would likely instill in Naruto a sense of order and routine. He would learn to manage his time better for training, and also be more meticulous in his study of jutsu. This new - found discipline could help him in all aspects of his ninja life, from mission planning to combat.
This adoption could have a huge impact on Naruto's character. He might become more introspective. Since Kakashi is a complex character, Naruto could start to think more deeply about his actions and the world around him. He may also become more reserved as he tries to live up to Kakashi's expectations, but at the same time, he'd still keep his core, energetic self.
Naruto would become more well - rounded. With Hiruzen's training, he'd gain more discipline. In the original, Naruto was a bit of a wild card. But under Hiruzen, he'd learn to control his impulses better. For example, in battles, he'd think more strategically instead of just charging in.
Naruto might become more of an isolationist. Danzo was not one to form close bonds easily. So Naruto could be more reserved and keep to himself. However, his natural urge for connection might still be there, and he'd struggle between his upbringing and his true nature. He could start off as a loner but gradually learn to open up as he experiences different things in the village and realizes that not all relationships are like the ones Danzo had.
It would make him more self - aware. By letting go of Sakura, Naruto is forced to look inward and understand his own emotions better. He becomes more in tune with what he really wants in a relationship and in life.
The cloak could make Naruto more confident. If it has special powers, he would feel more capable and in control. For example, if it gives him the power of invisibility, he might start to take more risks in battles and become bolder in his strategies.
He could gain a new sense of pride in his heritage. Since the Uchiha are known for their power, Naruto might feel a stronger drive to prove himself worthy of his mother's bloodline. This could lead to him training even harder and achieving new levels of power more quickly. For example, he might develop a unique fighting style that combines Uzumaki and Uchiha techniques.
Well, Naruto's character would be severely altered. Danzo is all about the end - justifying - the - means type of person. Naruto would be trained in a very different way. He'd probably be more proficient in stealth and assassination techniques rather than the flashy jutsu he learned under Jiraiya. His sense of justice would be warped. Instead of believing in everyone and trying to save his enemies, he might be more inclined to eliminate threats preemptively, like Danzo. His relationships would also be affected. He might not have the same close - knit group of friends as he did in the original story.
