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 Kurama is Naruto's father in fanfiction, the story would be drastically different. Naruto's family history would be reimagined, and this would impact how he is perceived in the Leaf Village. His status as a jinchuriki would become more complex, as it would be intertwined with his family heritage. The way he interacts with the Akatsuki, who are after the tailed beasts, would also change. His relationships with his mentors, like Jiraiya, could be affected as they might have to deal with this new family dynamic. Additionally, Naruto's role in the overall plot of the fanfiction, which could be different from the original, would be shaped by this new family connection.
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.
One possible consequence could be that Naruto's body takes a huge toll. Since Kurama is such a powerful entity, summoning him might drain Naruto's chakra to a dangerous level, leaving him vulnerable after the summon. In some fanfictions, he might even pass out immediately after Kurama is summoned.
Well, Naruto's mental state could be affected. Since Kurama has a very strong will, Naruto might have to struggle more to keep his own personality intact while merged. On the other hand, it could also lead to a deeper understanding between them, which in turn could result in Naruto being able to access Kurama's memories and knowledge. This could give him an edge in battles as he might learn about ancient fighting techniques or secrets of the ninja world.
One consequence could be a shift in the power dynamics. Since Sesshomaru is a very powerful demon, his being Inuyasha's father might mean that Inuyasha has access to more power or knowledge. For example, Sesshomaru could train Inuyasha in ways that no one else could.
In fanfiction, if Orochimaru is Sakura's father, it might change her relationships with other characters. For example, her friends like Naruto and Sasuke might view her differently. Naruto might be more cautious around her, fearing she has Orochimaru's evil tendencies. And Sasuke might have a more complex relationship with her, given his history with Orochimaru.
One implication is a change in their power dynamic. If Kurama is a pet, Naruto may seem more in control. Also, it can create more comical situations.
One consequence is a change in his physical strength. Kurama provided Naruto with a huge boost in power, so without it, he might not be as strong in terms of brute force. However, this could also force him to become more strategic in combat.
One possible consequence is that Naruto's body might not be able to handle Kurama's full power all at once. It could lead to physical harm or even death if not managed properly. Also, his relationships with Sakura, Sasuke and others would be in jeopardy as they might not recognize the Naruto under Kurama's control.
One consequence could be that Naruto became extremely powerful all of a sudden. This newfound power might have made his enemies fear him more. For instance, the Akatsuki members who were after him might have had to re - evaluate their strategies.
Naruto would gain better combat awareness. Kurama's experience in battles can be passed on to Naruto. He'll be able to read his opponents better, know when to attack and when to defend. This will make him a more formidable opponent in combat situations.
