Since Kurama has a vast amount of knowledge and power, he could guide Naruto in ways that no one else could. Naruto could learn to transform into different forms of the Nine - Tails more easily and use that power more effectively in combat. This would make his training more focused on harnessing his in - born abilities.
The training environment might also change. Instead of the normal Hidden Leaf training grounds, Naruto could be trained in a more isolated or special place related to Kurama's past. This would give Naruto a different perspective on his power and how to use it for the good of the village.
Yes, in certain fanfictions. Fanfic writers like to play around with established concepts. They might see Kurama's close bond with Naruto and decide to create a scenario where Kurama is Naruto's father. This can lead to really interesting and unique story developments that deviate from the normal Naruto narrative.
If Kurama becomes Naruto's father in fanfiction, it could completely change Naruto's character development. He might inherit more of Kurama's powers directly. For example, he could have better control over the Nine - Tails' chakra from the start, without having to struggle as much as in the original story.
In terms of physical training, Naruto would need to train his body to withstand the greater power of both Kurama halves. He could do more strenuous exercises like lifting extremely heavy weights or running at high speeds for long distances while in a Kurama - enhanced state. Also, his mental training would be crucial. He would need to be mentally strong to handle the influence of both Kurama halves on his mind and to be able to access their power when needed without losing control.
One consequence could be a change in Naruto's identity. He might have a different view of himself and his place in the ninja world. Another is that his relationship with the other characters, like Sasuke or Sakura, could be altered as they might view him differently. Also, his power origin might be more directly related to Kurama, and he could have access to different forms or abilities earlier.
If Naruto was raised by Kurama, his character would likely be more in tune with his fox - like instincts. He might be more solitary at first, as Kurama is a rather solitary being. But over time, he would learn the importance of bonds from Kurama's own experiences. His confidence would be sky - high, knowing he has the power of Kurama within him from the start. He'd also be more attuned to chakra control, as Kurama could teach him from a young age.
Well, Kurama could introduce Naruto to some new jutsu that are more in line with Kurama's own power. Maybe Naruto starts using more shadow - clone - based attacks in a different way. Instead of just creating a bunch of clones for distraction, he could use them in combination with Kurama's chakra to perform a more complex and powerful attack strategy. This would change his fighting style from a more straightforward one to a more strategic and powerful one.
The ninja way as it is known would be completely overturned. Naruto has always represented values like friendship, hard work, and never giving up. As Sauron, he would promote values of domination and power over others. Shinobi training might change to focus more on dark arts and subjugation. Younger ninjas would be influenced by this new Naruto, and the future generations of the ninja world would be shaped in a very different and darker way.
The entire ninja world's view of good and evil would be challenged. Naruto was always on the side of good, but as Lucifer, he represents a different set of values. This could cause a moral crisis among the ninja. Young ninja who looked up to Naruto would be confused. The shinobi code might need to be re - evaluated. Also, the spiritual balance in the world, which was maintained by the natural chakra and the various jutsu, would be thrown off. Naruto's new Lucifer - like powers, which could be based on dark and unknown energy, would disrupt the existing energy flow and could potentially lead to disasters such as natural catastrophes or the awakening of ancient evils that were once sealed away.
The impact would be huge. Naruto has always been a symbol of hope and friendship in the Naruto world. If he becomes like Obito, that symbol would be shattered. His friends and allies would be in shock and confusion. Konoha would likely be thrown into chaos as they try to figure out what happened to Naruto and how to deal with his new, potentially dangerous mindset.
It could have a positive impact on Naruto's training. If the news spreads, some of the more experienced shinobi who knew Minato might offer to train Naruto in techniques specific to the Namikaze clan. For example, they could teach him advanced wind - style jutsu that Minato was known for.
