If Naruto were the grandson of the Sannin, his training would incorporate the unique skills of each Sannin. He could learn Jiraiya's toad - related jutsu more in - depth, including some secret ones not known to others. With Tsunade's influence, he'd get better at medical ninjutsu and perhaps even learn how to use her super strength more effectively. And from Orochimaru, he might learn some dark arts - like techniques but use them for good, with a different moral perspective.
The training would be different in that it would be more personalized. The Sannin would know Naruto's potential better as a family member. They could focus on his weaknesses more precisely. For instance, if Naruto had trouble with long - range attacks, they could develop a training plan specifically for that. Also, the training would be more about legacy. The Sannin would want Naruto to carry on their names and skills, so they would train him not just to be a strong ninja, but also to uphold their values and reputations in the ninja world.
His training would likely be more intense and diverse. He might have access to the Sannin's personal training regimens. For example, if he was related to Orochimaru, he could be exposed to more experimental and dangerous forms of training. If related to Tsunade, there would be a stronger focus on chakra control and physical strength training.
Since Tsunade is known for her medical skills, Naruto could be trained in advanced medical ninjutsu much earlier. This would not only make him a more versatile shinobi but also give him an edge in battles as he could heal himself and his comrades quickly. Jiraiya, on the other hand, would introduce Naruto to more complex and dangerous combat scenarios. His training might involve long - distance missions and battles against powerful opponents to toughen him up. Also, the combination of Tsunade's strict discipline and Jiraiya's more laid - back but still effective teaching style would create a unique learning environment for Naruto.
In Uzushiogakure, there could be a greater emphasis on stealth and guerrilla - like tactics. Naruto's training would then include learning how to move quietly, set traps, and ambush enemies effectively. This would make him a more well - rounded ninja, as these skills would complement his existing strength and determination. Additionally, he might train with different weapons that are more common in Uzushiogakure, such as specialized water - resistant blades.
Well, Naruto's character development would be a complex journey. Since Danzo was known for his secrecy and manipulation, Naruto might initially be more guarded and less trusting. He would have to learn to be open and friendly in a different way. Also, his power development could be affected. Instead of just focusing on the Rasengan and Sage Mode, he might be more interested in some of the jutsu or techniques that Danzo had access to. But at the same time, he would have to decide if these were morally acceptable. His relationships with other characters like Kakashi, who had his own issues with Danzo, would also be a major part of his character growth. He would have to navigate through the web of relationships and loyalties in a new way compared to the original Naruto.
His training would likely be more intense. Since Kyuubi is a very powerful being, she would push Naruto to his limits. For instance, she might teach him more advanced chakra control techniques earlier than in the original story.
His training would likely focus more on water - based techniques. Mei Terumi is skilled in water jutsu, so Naruto would probably master things like water clones and water dragon jutsu much faster.
He might be more laid - back. Naruto was always hyper - energetic and eager to prove himself. His grandson, having grown up in a more stable and peaceful era (assuming so), could be more relaxed. He may not have that same intense drive for recognition all the time.
His friends would likely see him in a new light. They might respect him even more. For example, Sasuke might view Naruto as an even greater rival now that he has the status of a Sannin. And his other friends like Sakura would be proud of him and might rely on him more for difficult missions.
His training would likely be more intense. Since he has the blood of Kyuubi, he might have a natural affinity for chakra control and large amounts of chakra. So, his training could focus on refining and mastering this huge chakra reserve from an early age. For example, he could be taught advanced chakra - based jutsu much earlier than in the original story.
Naruto's development would be different as he would grow up with the weight of the Uchiha legacy. He may be more focused on mastering Uchiha techniques and understanding their history. This could lead to a more serious and less impulsive Naruto, at least in the beginning. As he progresses, he might learn to balance his Uzumaki and Uchiha sides, which would be a major part of his character growth.
His sense of honor might be different. Spartans had a strong code of honor. Naruto, as the grandson of Sparta, would likely have a more rigid view of honor. He might be less willing to make compromises that go against his newfound sense of honor, which could lead to some interesting conflicts with his friends and the Hidden Leaf Village, as they are used to his more flexible approach.
