Naruto might also face emotional burnout. If he's constantly pushing himself in his relationships, he could end up feeling drained. For example, if he's always trying to be there for everyone but not getting the same support back, he could become depressed or angry. This can then affect his performance as a ninja and his relationships further.
There could also be emotional consequences. If he pushes himself too far in the heat of battle or in pursuit of a goal, he might alienate his friends and allies. They may be worried about his well - being and feel that he's being reckless. This could lead to strained relationships until he learns to find a balance between pushing his limits and taking care of himself.
Obviously, Naruto is one of the main characters as the title implies. He's the one who's constantly pushing his limits. Sakura might also be an important character, perhaps as a support to Naruto in his growth, providing medical assistance or strategic advice during his adventures.
One possible reason could be the burden of his past. Naruto has faced a lot of hardships and the memories might be overwhelming him, making him want to be alone. For example, the loss of his master Jiraiya might have left a deep scar, and he might feel that isolating himself is the only way to deal with that pain.
Maybe he feels a sense of guilt. For example, if something bad happened in the village that he blames himself for, even if it wasn't really his fault. He could exile himself as a form of self - punishment. He has always been very hard on himself when it comes to the well - being of the village and his friends.
In this kind of fanfiction, one exciting plot could be Naruto mastering a new and extremely powerful jutsu. For example, he might combine different elemental chakra in a way no one has thought of before, like mixing lightning and water chakra to create a unique attack. This new jutsu could give him an edge in battles against strong foes.
Well, while there might be some out - of - character fanfictions out there, the general perception of Naruto is that he is a very selfless character. His whole journey in the original story is about protecting others and achieving peace for everyone. So, in fanfiction, it's not very common for him to be portrayed as only caring for himself. Usually, the essence of his character is maintained, which is his altruism.
In some fanfictions, Naruto might distance himself because he discovers some dark secrets about the ninja world or his own past. These revelations could shock him so much that he needs time alone to process and figure out how to deal with them.
Perhaps in the fanfiction, Naruto discovers some dark secrets about his past, like his family's involvement in something he considers immoral. This new knowledge could make him question his own identity and lead to self - hatred. He might feel that he's a product of something bad and that he can't escape this 'taint' no matter how hard he tries.
In fanfiction, Naruto sacrificing himself for Obito could be a very emotional and dramatic concept. It might show Naruto's ultimate selflessness, believing that Obito is worth saving at the cost of his own life. This could be due to Naruto seeing the good in Obito that others might not, like the part of Obito that was once a kind - hearted shinobi.
