Jiraiya's character would grow in terms of emotional depth. In the original Naruto story, he was often seen as a bit of a joker and a ladies' man. But with a son from time travel, he would have to face the consequences of his past actions more seriously. He would have to be a role model, which means he might have to change some of his bad habits. He would also learn to be more selfless as he puts his son's needs above his own desires, whether it's for writing his books or going on dangerous missions alone.
Jiraiya would likely become more protective. He has always been a bit of a free spirit, but with a son in the picture due to time travel, he would be more cautious. His focus would shift from just his own adventures and spying to ensuring his son's safety and growth.
Well, in this fanfiction scenario, perhaps Jiraiya's time travel is an accident. His son could be a half - breed, part - something special like a jinchuriki of a new tailed beast. Jiraiya then has to use his knowledge from the past and new skills he learns in this timeline to protect his son and the village from those who want to use the son's power for evil.
Their relationship would be very strong. Jiraiya would see Naruto as not just a student, but also as a connection to Minato. He would be strict but also very affectionate. Naruto would look up to Jiraiya as a father figure, since he never really had one. They would share many adventures together, with Jiraiya teaching Naruto about life, love, and ninjutsu.
He might be more confident from the start. Since Jiraiya is known for his charisma and self - assurance, Naruto could inherit some of that. He may not be the underdog we saw in the original series as much.
Naruto's character would become more cynical. He'd lose his usual optimism and be more distrustful of others. His sense of justice might be warped, as he now feels that he has been wronged. He could start to see power as the only thing that matters, rather than the bonds he once cherished.
Their relationship could become more of a peer - to - peer one. Since Naruto already has a lot of knowledge and skills from his future self, he might be able to offer new perspectives to Jiraiya. Jiraiya could see Naruto in a new light and start to rely on him more in certain situations.
The training makes Naruto more confident in his abilities. Jiraiya constantly challenges Naruto and as Naruto overcomes these challenges, he realizes his own strength. He starts to believe in himself more, which is evident in the way he faces stronger opponents without hesitation later on. Also, Jiraiya's teachings about the ninja way and the importance of protecting those you love make Naruto more determined and focused on his goals.
Jiraiya's reaction might be complex. He might be in awe of Naruto's new power but also sad about his departure. He could see it as a natural progression in Naruto's journey, yet still feel a pang of loneliness. He might start to reflect on his own life and training methods, wondering if he could have done something differently to keep Naruto with him. At the same time, he would be eager to see what Naruto will achieve in the world with his newfound abilities.
In this fanfiction, their relationship would be transformed. They would be like a married couple in a way, but without the formalities. Jiraiya would probably tone down his womanizing ways as he has a family to think about now. Tsunade would be more open and less prickly around Jiraiya. They would bicker less and cooperate more. Their relationship would be centered around Naruto, and as he grows, they would grow together as a family unit, with their bond getting stronger over time.
Naruto's character would become more complex. With the Rinnegan and Jiraiya's training, he'd be more confident. He might become more of a strategist, using the Rinnegan's insights and Jiraiya's wisdom. His sense of justice could also evolve, as he'd have more power to enforce it.
Jiraiya's training in the fanfiction might focus on Naruto's inner strength as well. He could help Naruto better understand and control the Nine - Tails' power. This new - found control would give Naruto a sense of calm and authority. His character would shift from being just a loud - mouthed underdog to a more respected and powerful ninja. Naruto would also learn about loyalty and sacrifice from Jiraiya, which would shape his values.
