Well, initially, Naruto might show kindness towards the Nine - Tails despite it being a powerful and somewhat feared entity. He could try to communicate with it on a deeper level. The Nine - Tails, in turn, might be intrigued by Naruto's tenacity. As time passes, they begin to trust each other more. Naruto may share his dreams and fears with the Nine - Tails, and the Nine - Tails might start to see Naruto as someone worthy of its friendship.
Maybe through new jutsu or abilities. The fanfiction could give Naruto some unique power that allows him to communicate or negotiate with the Nine - Tails on a different level. He could use this power to show the Nine - Tails a different perspective, like the potential for harmony between them instead of constant struggle.
Naruto's character might develop a deeper sense of self - awareness. With the Nine - Tails Cloak, he realizes he has a greater power and responsibility. He becomes more cautious in using it, understanding the consequences of losing control.
Another unique exploration could be through a shared goal that is not related to the main Naruto plot. For example, they both want to protect a special place in the spirit world that has significance for the Nine - Tails. To do this, they have to work together in a way that they haven't before. Naruto has to use his human skills and the Nine - Tails has to use its tailed - beast powers in harmony. This would show a different side of their relationship, one based on mutual respect for each other's abilities.
One key moment could be when Naruto is in a tough battle and the Nine - Tails willingly lends him extra power without hesitation. It shows that the Nine - Tails trusts Naruto enough to let him use its strength.
A very unique way to develop their relationship would be if they could communicate without words. It could be like an instinctual understanding between them. For example, in the heat of battle, Naruto just knows what the Nine - Tails wants him to do and vice versa. This could start with small moments, like Naruto instinctively knowing when the Nine - Tails is in a bad mood or wants some space, and over time, it could grow into a very strong and unique bond that no one else in the ninja world has.
At first, Naruto might see the Nine - Tails as just a source of power, something that makes him strong. But as he grows, he starts to see it as a part of himself, an entity with its own feelings and history.
Naruto's relationship with his friends undergoes significant changes. His closest friends like Kakashi would be on high alert. Kakashi would constantly be watching Naruto to make sure he doesn't lose control. With his peers, some might start to distance themselves, fearing the unpredictable nature of the Nine Tails' power. However, true friends like Rock Lee would see it as an opportunity for Naruto to grow stronger. Lee might encourage Naruto to master the Nine Tails' power and use it for good. Naruto's relationship with his friends becomes a complex web of trust, fear, and support as he deals with the Nine Tails' possession.
One great 'Naruto Nine Tails Fanfic' is 'The Nine - Tailed Fox's Legacy'. It delves deep into the relationship between Naruto and the Nine - Tails, exploring how they grow together and face new challenges. Another interesting one is 'Nine Tails' Power Unleashed' which focuses on Naruto's journey to fully master the power of the Nine - Tails in unique and unexpected ways.
To develop the baby nine - tails, it could be given a unique personality trait such as being very empathetic. So, it can not only feel Naruto's emotions but also those of other villagers. This causes it to try and bridge the gap between Naruto and the villagers who fear it. It might go out of its way to show the villagers that it means no harm, which in turn would make for an interesting character arc as it tries to change the perception of the nine - tails in the village.
Sometimes, other characters from the Naruto universe might also play important roles in these fanfictions. For example, Kakashi could be involved as Naruto's mentor, giving advice on how to better communicate with the Nine - Tails. Or Sakura might be there to support Naruto in his journey of befriending the Nine - Tails, even if she doesn't directly interact with the tailed beast.
