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.
His character would develop with a stronger sense of loyalty towards Jiraiya. He would inherit Jiraiya's values like protecting the weak and seeking justice. Naruto would also be more well - versed in the ninja arts and history due to Jiraiya's teachings. This would make him more respected among his peers at an earlier stage. Moreover, he might be more patient and less impulsive as Jiraiya could teach him the importance of thinking before acting.
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.
Naruto would become more mature. Jiraiya's influence would make him think more about the long - term consequences of his actions. He'd also become more strategic in battles as Jiraiya is a master strategist.
His character would likely become more mature faster. Being in the Jiraiya era, he'd see the harsher realities of the ninja world at an earlier stage. For instance, he might witness more battles and political intrigue up close, which would force him to grow up quickly.
In this fanfiction, Jiraiya could be more open with Naruto about his past mistakes and love life. This would make Naruto see Jiraiya in a different light and might inspire him to be more cautious in his own relationships. Also, Naruto could be more protective of Jiraiya, knowing all that his master has been through. They would support each other not just in ninja battles but also in personal matters.
Naruto would likely develop his chakra control better. The toads could teach him unique ways to manage his chakra, like using it in harmony with the natural energy around him. This would make his Rasengan and other jutsu more powerful.
One possible scenario in such a fanfiction could be that Jiraiya's son discovers a forbidden jutsu that allows him to time - travel. He decides to go back in time to prevent some great tragedies in the Naruto world. He might try to stop the Uchiha massacre, which would change the whole dynamic of the story. This could lead to different alliances and power structures, as Sasuke wouldn't have the same motivation for revenge.
