Well, in a way it depends on the context of the fanfiction. If the writer decides to give Naruto some sort of super - powered boost or if Jiraiya is weakened in some way. For example, if Naruto has some unique power - up that allows him to counter Jiraiya's toad - related jutsus easily. But Jiraiya is a very experienced and powerful shinobi too, so it's not a straightforward win for Naruto without some plot devices.
In some fanfiction, Naruto's betrayal of the Leaf can seem plausible. It might be due to a misunderstanding, like the village turning against him despite his years of service. For example, if the village leaders suspect him of a crime he didn't commit, he could feel pushed to the edge. However, in the original Naruto series, his loyalty to the Leaf is a core part of his character.
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.
Well, in a fanfic where Anakin beats Obi - wan, it might be due to Anakin's raw power potential finally being fully unleashed. Anakin had incredible Force abilities that were often held back by his internal conflicts. In this fanfic scenario, perhaps he overcame those conflicts in a different way, allowing him to focus all his power on the fight against Obi - wan. Also, external factors like the environment could play a role. If the battleground was more favorable to Anakin's fighting style, it could give him the upper hand.
In a more psychological approach, Naruto could have grown so much as a character that he no longer fears Kakashi's reputation. This new - found confidence could change the dynamics of their fight. He might be able to read Kakashi's moves better and anticipate his attacks. Combined with his own ever - improving skills, Naruto could defeat Kakashi in this state of mental superiority.
It could be. Naruto has always looked up to Tsunade. In fanfiction, this could be twisted into a romantic relationship. Tsunade is a powerful and alluring character. Naruto, with his big heart, might find himself falling for her. However, it would be a complex relationship considering their age difference and the power dynamics at play. But in the realm of fanfiction, all these elements can be explored and molded into a believable love story.
One reason could be jealousy. Suppose Naruto had achieved something that Sakura deeply desired for herself or for someone she loved, and in a fit of envy, she took drastic action. But this would be a very out - of - character move for the Sakura we know from the original series.
Perhaps in this fanfiction, Jiraiya discovers that Naruto is going to be the cause of a major catastrophe in the future. He might have seen a prophecy or some sort of sign that convinces him Naruto has to die to prevent this. It could also be that Jiraiya has been misled by false information about Naruto, which makes him think that Naruto has become an evil force that needs to be eliminated.
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.
One great Jiraiya and Naruto fanfiction is 'The Mentor's Legacy'. It delves deep into how Naruto continues to uphold Jiraiya's teachings long after his death. It shows Naruto using the skills and wisdom passed down by Jiraiya in his battles and in his leadership of the village. Another interesting one is 'Jiraiya's Unfinished Business'. In this story, Naruto discovers some of Jiraiya's hidden notes and secrets that he left behind, which leads him on a new adventure to complete what Jiraiya started.
One possible scenario in this fanfiction could be that Naruto grows up with a more balanced upbringing. Tsunade might teach him medical ninjutsu and how to control his emotions better. Jiraiya, on the other hand, would surely train him in powerful combat techniques and in the ways of the sage. Naruto would probably be more mature and well - rounded at an earlier age, with a combination of Tsunade's tough love and Jiraiya's adventurous spirit guiding him.
