Well, it could be that Naruto's personality is shaped in a new way. Since Karma has its own nature, Naruto might become more of an enigma to others. His training methods would likely change too. Instead of the traditional Konoha training, he might have to adapt to the strange energy of Karma. And perhaps he would attract different types of enemies or allies. Maybe some ancient forces would sense the Karma within him and either try to control or help him.
In such a fanfic, the plot might involve Naruto growing up with the influence of Karma. Maybe he gains unique powers from it. For example, his physical abilities could be enhanced, allowing him to perform jutsus more easily. Also, his understanding of the ninja world could be different, as Karma might bring some knowledge from another realm. He could form new relationships based on this new power source, and face different challenges compared to the original Naruto story.
In this kind of fanfic, Naruto's character might develop in a way that he is more attuned to the spiritual side of the ninja world. Since Karma has some sort of otherworldly origin, he could start to see things from a different perspective. He might be more empathetic towards enemies who also have strange powers, as he understands the burden of having something that others don't understand. His growth would be about not only physical and ninja skills but also about his understanding of different forces at play in the world.
Well, the plot could involve Naruto growing up with the Akatsuki's unique values. He might learn different jutsu from the members. For example, he could pick up some of Hidan's immortality secrets or Kisame's water jutsu skills. His view of the ninja world would be shaped by the Akatsuki's goal of bringing change, which is different from what he would have learned in Konoha.
Well, the plot could involve Naruto being trained in Orochimaru's lair. He'd be exposed to Orochimaru's experiments and might gain some unique powers from them. For example, he could have better control over snakes or learn some snake - based jutsu. His view of the ninja world might also be warped as he grows up in Orochimaru's influence, seeing things more from a survival - of - the - fittest perspective.
Well, in this fanfic, maybe Naruto is an orphan in Erza's world from the start. Erza, seeing his potential and his kind heart, decides to raise him. She teaches Naruto discipline, which is something he might lack initially. Naruto, in turn, brings his never - give - up attitude to Erza's guild. They go on adventures where Naruto uses his shadow clones to help out in different tasks, like rescuing people or fighting off dark magic users. And Naruto also starts to adopt some of Erza's sense of justice.
Well, it could have Minato training Naruto from a young age. Naruto might grow up more confident and with better control over his chakra earlier. He'd probably be less of an outcast in the village too.
Well, Naruto might develop a very different set of skills. Pain's techniques are quite distinct. He could teach Naruto about the Rinnegan's powers and how to use them. Naruto might also become more isolated from the Hidden Leaf Village as Pain has little regard for the traditional village system. So, he could be more of an outcast ninja with a different moral compass.
In this fanfic, Naruto's relationship with the other villagers might be quite different. Since he is raised by the ANBU Commander, he may be more isolated from the general populace at first. However, as he grows, his skills and the influence of the ANBU could lead to him being respected in a different way. Maybe he would form a special team within the ANBU itself rather than the normal genin teams.
Well, in this fanfic, Obito might raise Naruto to be more cynical about the Hidden Leaf Village. Since Obito has his own grudges against the village, he could influence Naruto's perception of it. However, Naruto's own kind heart might still shine through and he could end up trying to change Obito's views while still learning from him. For example, Naruto could use the power and skills he learns from Obito to protect the village in a new way, bridging the gap between Obito's distrust and the village's need for protection.
Well, perhaps in this fanfic, Naruto being raised by Mikoto means he has a more stable and loving upbringing. He could be friends with Sasuke from a very young age, and they might grow up like brothers. Naruto would also be exposed to the Uchiha's rich history and culture, which could shape his understanding of the ninja world and his own place in it. He might even get to know some secrets of the Uchiha clan that no one else outside the clan knows.
Well, one possible plot could be that Naruto grows up learning the Raikage's style of combat. He might become more physically powerful and aggressive compared to his canon self. Maybe he'd also form strong bonds with the Cloud ninja early on.
