One possible fanfic could involve Naruto learning unique jutsu from Jiraiya due to his Rinnegan. Maybe Jiraiya, with his vast knowledge, would train Naruto in ways that are different from the original story. For example, Naruto could master space - time ninjutsu related to the Rinnegan earlier, which would give him an edge in battles against stronger opponents like Akatsuki members. He might also use the Rinnegan to understand the secrets of the tailed beasts more deeply, leading to a different relationship with Kurama.
He would probably be an even more powerful ninja. Jiraiya could teach him amazing jutsu and Tsunade could train him in physical combat and medical ninjutsu. He'd likely have a more well - rounded skill set.
One interesting plot point could be how Naruto's relationships with his friends change. With the Rinnegan, he might seem more distant or different to them at first. But as he grows and learns to control it, they could come to rely on his new powers. Another point is how the ninja villages react to Naruto having the Rinnegan. Some might fear him, while others might try to recruit him. And of course, there's the mystery of how he got the Rinnegan in the first place.
One possible plot twist could be that Naruto develops a different fighting style. Since Tsunade is strong in physical combat and medical ninjutsu, and Jiraiya is a master of various ninjutsu and toad summons, Naruto might combine their teachings in unique ways. For example, he could use medical ninjutsu to enhance his own physical abilities during combat, similar to how Tsunade uses her strength. Another plot twist could be in his relationships. With Tsunade and Jiraiya as his guardians, he might have a different attitude towards the Hidden Leaf Village's elders. He could be more critical or more understanding depending on how they've influenced him. Also, his training might be more focused on stealth and intelligence gathering, skills that Jiraiya was good at, rather than just brute strength.
His training would be more comprehensive. Jiraiya could teach him Sage Mode earlier and more effectively. Tsunade could focus on his chakra control for medical ninjutsu.
One possible reason could be that Naruto feels he has learned all he can from Jiraiya at that point. Maybe he wants to explore his own path independently and test his skills without Jiraiya's constant guidance.
In such a fanfiction, Jiraiya would likely introduce Harry to a different kind of discipline. Instead of the strict Hogwarts rules, Harry could be more free - spirited. Jiraiya might take Harry on adventures all over the wizarding and ninja worlds. Harry would grow up with a sense of adventure and mystery, learning about both magic and ninjutsu. He could also develop a very different personality, perhaps more confident and bold in facing challenges, as Jiraiya's influence would encourage him to take risks and explore the unknown.
Jiraiya might comfort Naruto by sharing his own experiences. He could tell Naruto about the times he faced difficulties and how he overcame them. For example, he might talk about his training with the toads and how he grew stronger through perseverance.
One possible reason could be that Naruto feels he has learned all he can from Jiraiya at that point. Maybe he has reached a level in his training where he believes he needs new experiences and challenges that Jiraiya can no longer provide.
Well, Naruto's character development would take a different path. Physically, he might be more in tune with his body's limits and capabilities. Tsunade's medical knowledge could help him understand how to train without overexerting himself and also how to heal faster. Mentally, he would be more complex. Jiraiya's teachings about the nature of the world and Tsunade's no - nonsense attitude would make him question things more deeply. His view of friendship might also change. He would still value his friends, but he might be more cautious about who he fully trusts. His goal of becoming Hokage might not be just about being recognized, but more about truly leading and protecting the village in a more practical sense, having learned from Tsunade's leadership style.
