One common plotline is the Kyuubi teaching Naruto new and powerful jutsu. Since the Kyuubi has a vast amount of chakra and knowledge, it could share unique techniques with Naruto that are not part of the regular ninja training. Another plotline could be the Kyuubi's influence on Naruto's relationships. For example, some fanfictions explore how Naruto's connection with the Kyuubi affects how his friends and villagers perceive him. It can also lead to some interesting character development as Naruto has to learn to control the Kyuubi's power without being consumed by it.
In Naruto fanfiction, Kyuubi can help Naruto by providing him with extra power. For example, it can enhance Naruto's physical abilities like strength and speed during battles. This allows Naruto to face stronger opponents more easily.
In some fanfictions, the Kyuubi's power could be depicted as more spiritual. Instead of just raw chakra, it could have elements of ancient wisdom and spiritual energy that Naruto can tap into. For example, Naruto might be able to use the Kyuubi's power to communicate with the spirits of the past. Another way is to show the Kyuubi's power as having different forms. Maybe there's a 'benevolent' form of the Kyuubi's power that Naruto can access for healing or peace - making purposes, as opposed to the more destructive form we usually see.
Well, Kyuubi could help in Naruto fanfic in several ways. It might offer its wisdom to Naruto. Since it has lived for a long time and has seen a great deal, it can give Naruto insights about the history of the ninja world, hidden techniques, or the true nature of certain characters. Also, its presence within Naruto can act as a deterrent to some villains who fear the power of the nine - tailed fox.
Well, the Kyuubi might use its chakra to soothe Naruto's emotional pain. It could send warm waves of its powerful chakra through Naruto's body, making him feel more at ease and less heartbroken.
Yes, in some fanfictions, Naruto is often depicted as the Kyuubi or having a very close connection to it. This can lead to really interesting and unique storylines that deviate from the original plot.
In many Naruto fanfictions, Naruto might have developed some new and unique abilities that the Kyuubi has no defense against. This could make the Kyuubi, which is used to being a dominant and feared force, feel vulnerable. For example, if Naruto has the power to nullify the Kyuubi's chakra or to manipulate it in a way that goes against the Kyuubi's will, it would be a cause for fear.
Maybe it's because Naruto has some sort of special connection or resemblance to the Kyuubi that Kushina notices. For example, Naruto might display some of the Kyuubi's power characteristics in an obvious way that makes Kushina jump to that conclusion.
At first, Naruto might see the Kyuubi as just a source of power. But as he starts to protect it, he realizes it's more of a partner. Their relationship evolves from a simple user - power source dynamic to a deep - seated friendship. He begins to understand the Kyuubi's emotions and past, which further cements their bond.
Sasuke is often a popular character in these fanfictions. His relationship with Naruto can be further explored in the context of the Kyuubi's fatherly influence. Maybe Sasuke is initially skeptical of this new - found bond between Naruto and the Kyuubi but later comes to accept it. Sakura is also a common character. She might notice the changes in Naruto due to the Kyuubi's fatherly presence and be either supportive or a bit jealous. Kakashi could also be there. He might be observing Naruto's growth under the Kyuubi's guidance and offer his own wisdom as Naruto's former teacher.
