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.
Yes, in some fanfictions, Naruto is often depicted as having a very special connection to the Nine - Tails that goes beyond the normal relationship in the original story. For example, he might be able to fully control the Nine - Tails' power in ways not shown in the canon, or they could have a mental bond that allows for unique forms of communication and cooperation.
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.
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.
In fanfiction, Naruto's protectiveness towards the Nine - Tails can stem from multiple reasons. Firstly, he has had a long journey of co - existing with it. They have a symbiotic relationship now. Secondly, Naruto has seen the power of the Nine - Tails and how it can be misused by others. He doesn't want that to happen. He also respects the Nine - Tails as a powerful entity. When it comes to threats against the Nine - Tails, Naruto uses his skills and his bond with it to safeguard it. He might even negotiate with others on behalf of the Nine - Tails to ensure its safety and well - being.
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.
Well, the Nine - Tails itself can be considered a popular 'character' in this type of fanfiction. It has its own personality and power, and many stories revolve around Naruto's interaction with it. Another character that might be popular is Gaara. Since he also has a tailed beast within him, there could be interesting interactions between him and Naruto regarding their respective tailed beasts, especially when it comes to the Nine - Tails.
One implication is the change in power dynamics. If Naruto is the Nine - Tails, he would be incredibly powerful, which could lead to different story arcs where he is either feared or revered. He might also face new enemies who are interested in his unique form.
One key point could be the initial confrontation. Naruto has to face the Nine - Tails' wrath head - on. This is a dangerous but necessary step as it sets the stage for their relationship. He might get seriously injured in this encounter but also learn a great deal about the Nine - Tails' power and nature.
