A lot of fanfictions play around with the visual aspect of Naruto's Kyuubi transformation. It could be more elaborate, with the chakra taking on different colors or forms. Some might write that the transformation gives Naruto new abilities that are not present in the original series, like the ability to fly or to communicate telepathically with the Kyuubi. This adds a whole new layer of excitement and creativity to the Naruto universe within the fanfiction.
One interesting aspect in Naruto's Kyuubi transformation fanfiction could be exploring the internal struggle Naruto has when the transformation starts. He's constantly fighting the raw power of the Kyuubi while trying to use it for good. In some fanfictions, the transformation is not just a physical change but also a mental one, where Naruto has to face his darkest fears and insecurities that are amplified by the Kyuubi's chakra.
Power control is a very common theme. Writers often explore how Naruto gains better control over the Kyuubi's power, whether it's through new training methods or emotional breakthroughs. Another common theme is the reaction of other characters. How do Sasuke, Sakura, and the other villagers respond to Naruto's new and sometimes terrifying form? It can range from fear to admiration.
Another aspect in such fanfictions could be the origin of the Kyuubi seal. Some writers might delve into ancient ninja secrets and forgotten jutsu that were used to create the seal in the first place. They might also explore if there were other possible ways to seal the Kyuubi that were considered but not used. This can add a whole new layer of mystery and intrigue to the Naruto universe.
One possible fanfiction could be about Naruto learning to fully control the power of his Kyuubi - enhanced eye. He might discover new abilities like seeing through illusions more easily or being able to project his chakra in a more powerful way through his eyes. This could lead to him having an edge in battles against tough opponents.
One possible fanfiction could involve Naruto learning a new technique that accidentally weakens the Kyuubi's seal, leading to a partial release of its power. This could put the Hidden Leaf Village in danger as Naruto struggles to regain control.
In some fanfictions, Naruto's mother, Kushina, has a special connection with the Kyuubi. For example, some stories might explore how Kushina's chakra influenced the Kyuubi's behavior. Since she was the Jinchuriki before Naruto, her relationship with the Kyuubi could be a rich source of plot development in fanfiction.
One interesting fanfiction could be where Naruto has an unexpected and more powerful tailed beast transformation during a major battle. Maybe he combines the power of all the tailed beasts in a new way, surprising his enemies and allies alike.
I'm not really sure as I haven't read that specific fanfiction. But generally, in Naruto fanfictions, if Naruto is the 'fem Kyuubi's slave', it might involve some sort of power dynamic where the female version of the Kyuubi has some control over Naruto. It could be a really strange or unique take on the Naruto universe, exploring different relationships and character developments that are far from the original storyline.
There probably is. Fanfiction is a place where writers can reimagine relationships. If Kyuubi was Naruto's older brother, it could rewrite many aspects of Naruto's life. For example, Naruto might have had a different upbringing with Kyuubi around. And it could also affect how Naruto deals with his enemies, as he would have the power and guidance of his older brother Kyuubi. It's a really interesting concept that fanfic writers might explore.
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.
In this fanfiction, their relationship becomes more of a partnership. Instead of Naruto just using the Kyuubi's power, they work together as brothers. Naruto might start to understand the Kyuubi's feelings and motives better.
