Well, in fanfiction, anything can happen. Naruto could be betrayed by the Leaf first, which then leads to his own betrayal. For instance, if the village exiles him unjustly, he might seek revenge or join another force. But this goes against his fundamental values in the main story. His dream was always to be Hokage and protect the Leaf, so for him to betray it, the circumstances would have to be extremely dire and out of his control.
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.
Naruto could respond with anger at first. He has given so much to the Leaf Village, and this betrayal would be like a slap in the face. However, his kind heart might also make him wonder if there is a misunderstanding. So, he could start by trying to communicate with the villagers he trusts. If that fails, he might leave the village for a while to get stronger and then come back to confront those who wronged him.
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 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.
A possible plotline could be that Naruto and Sasuke discover a new threat to the ninja world that requires them to use their combined skills in a way they never have before. They have to travel to far - off lands, facing various challenges along the way. During this journey, they grow closer as they rely on each other for survival.
At first, Naruto would be completely shocked. He has always seen Hinata as a loyal friend and someone who has deep feelings for him. So the idea of her betrayal would be hard to fathom. He might try to deny it at first.
In fanfiction, the idea of Naruto and Haku having a baby might be explored in an alternate universe setting. For instance, if there was a different timeline where Haku survived and their relationship developed into something more romantic. It would require a significant re - imagining of their characters' arcs. They would need to overcome many obstacles, like the fact that Haku was originally from the Hidden Mist and Naruto's loyalty to Konoha. But with enough creativity, a story could be crafted around their new family.
It could also be a misunderstanding. Hinata might be framed as a traitor. Some false evidence could be planted that makes Naruto and his friends believe she has betrayed them. This would lead to a lot of drama and conflict in the fanfiction as Naruto struggles with whether to believe Hinata or the evidence against her.
One possible reason could be that Naruto discovers some dark secrets within Konoha. Maybe he finds out that the village elders have been using him all along, not truly caring about his well - being but only his power as a Jinchuriki. This realization could be so shocking that he decides to turn against the village.
