On the character development side, Naruto might have to face his own insecurities and fears related to the Nine - Tailed Fox. He could learn more about his heritage and the power within him, which would make him grow as a character. This could be a central part of the plot in the fanfiction, as Naruto's journey of self - discovery is often a key element in Naruto - related stories.
It can completely turn the plot around. If the story was about Naruto being in a tough situation against a powerful enemy, summoning the Nine - Tailed Fox could be the solution to that problem. It could be like a deus ex machina moment, but also very exciting for the readers.
The Nine - Tailed Fox's appearance could also introduce new conflicts. For instance, other villages might see Naruto as a danger because of his connection to such a powerful and feared beast. This could lead to political tensions and new battles between villages.
It could make his friends more cautious around him. For example, Sakura might be a bit more hesitant to get close, fearing the power of the Nine - Tailed Fox. But at the same time, some like Sasuke might see it as an opportunity to become stronger by sparring with Naruto in this new form.
There are fanfictions where the Nine - Tailed Fox has a split personality. One side is the fierce and powerful beast, and the other is a more gentle and understanding entity. Naruto has to deal with both sides, which creates a very complex and different kind of relationship compared to the original series. This can lead to some really interesting character development for Naruto as he tries to balance and understand this unique relationship.
Well, one possibility is that Naruto gains an instant boost in power. Since the Nine - Tailed Fox is extremely powerful, he could easily defeat his enemies. For example, in a battle against a powerful Akatsuki member, with the Nine - Tailed Fox by his side, Naruto could use its chakra to perform stronger jutsus and outmatch his opponent.
His relationship with the villagers could become more complex. Some might see him as a greater threat, while others who have come to know Naruto as a hero might be more accepting. His transformation could also lead to new alliances as some might want to use his power for their own purposes, which Naruto would have to navigate carefully to protect his relationships.
Well, in some fanfictions, Naruto might start his journey after a particularly intense battle where he realizes the full potential of the Nine - Tailed Fox's power within him. It could be a fight against a strong enemy that makes him understand he needs to control the fox's power to protect his friends and the village.
She could change the power dynamics. In the Naruto universe, power is often associated with male characters. A female Naruto with the Ten - Tailed Fox would break that mold. Her presence might inspire other female characters to strive for greater power. For example, female ninjas could see her as a role model and start to train harder to gain similar levels of power.
When it comes to Sasuke, the Nine - Tailed Fox Faunus could be seen as a threat at first. But as the story progresses, they might find common ground in their pursuit of power and their desire to protect their own kind. The faunus could show Sasuke a different side of power, one that is more in tune with nature.
The Nine - Tailed Fox's death in the fanfic would change the balance of power among the tailed beasts. The other tailed beasts might have to re - adjust their relationships with each other and with the human world. Konoha would need to find new ways to defend itself without relying on the Nine - Tailed Fox's power. This could lead to new alliances being formed or old ones being broken. Also, the story of the Sage of Six Paths and the origin of the tailed beasts would be re - examined in a different light. Since the Nine - Tailed Fox was an important part of that history, its death would force the characters in the Naruto world to think about their past and future in new ways.
The nine - tailed fox could introduce new types of magic. For instance, it might have the ability to manipulate time in a different way than time - turners. This could disrupt the existing understanding of magic in the wizarding world. Maybe it can also create illusions that are so real that they can physically interact with the environment, which is something not seen before in the normal wizarding magic.
Her gender can change the way the village perceives her. In a male - dominated ninja world like Naruto's, a female with the 9 - Tailed Fox might face more discrimination. For instance, some might think she's not strong enough to control it. However, it can also be a source of strength. She can break gender stereotypes and prove that females can be just as powerful. For example, she might use her femininity to her advantage in battles, using grace and agility in ways that male Naruto didn't.
