If Kyuubi takes over Naruto in a fanfic, it would be a chaotic situation. Naruto has always been a symbol of hope in the village, but with Kyuubi in control, that would all change. The Kyuubi's instincts for destruction would come to the forefront. The fanfic could explore how Naruto's relationships are affected. For example, Sasuke might see this as an opportunity to become stronger by fighting the Kyuubi - possessed Naruto, or Sakura could be torn between her fear of the new Naruto and her love for the old one. Also, the village elders would have to decide whether to try to contain or eliminate Naruto, which could lead to some very interesting power struggles and moral dilemmas within the village.
Well, if Kyuubi takes over Naruto in a fanfic, Naruto's physical appearance would probably change. His eyes might turn red like the Kyuubi's, and his chakra would be out of control. The story could focus on how the village reacts to this new threat. Some might see Naruto as a lost cause, while others, like his closest friends, would fight to save him.
If Kyuubi takes over Naruto in fanfiction, Naruto might become a much more powerful and uncontrollable force. His appearance could change, perhaps taking on more fox - like features. He would likely lose his sense of self and act on the Kyuubi's primal instincts, which could lead to chaos in the Hidden Leaf Village as he would no longer be the friendly and determined ninja they knew.
If Kurama takes over Naruto in fanfiction, it could lead to a shift in the power dynamics. The village might be in danger as Kurama's takeover could mean Naruto loses his usual self - control. But on the other hand, it could also open up new storylines where the other characters have to find a way to bring Naruto back, perhaps by appealing to their past bond or using some long - forgotten jutsu.
Well, one possibility is that the story would have a very different comedic tone. Ranma's curse and his more light - hearted, slapstick - prone nature could lead to some really wacky adventures in the Naruto world. For example, his interactions with the various ninja clans might involve more misunderstandings and physical comedy compared to Naruto's more serious and determined approach.
The story could progress with the village trying to subdue Naruto. They might call on all their strongest ninja, like Kakashi or even the Hokage. Meanwhile, Naruto could be on a rampage, causing destruction everywhere.
If Naruto is trained by Kyuubi in a fanfic, it would change a lot of things. Firstly, Naruto's relationship with the Kyuubi would shift from a more adversarial one (initially) to a mentor - student relationship. Kyuubi could train Naruto to use its chakra more efficiently, which would enhance Naruto's physical abilities like speed, strength, and endurance. Naruto might also gain a deeper understanding of the nature of chakra itself. Kyuubi could pass on some of its ancient knowledge about the ninja world, and this could help Naruto in his quest to protect the village and his friends. Moreover, Naruto's standing in the ninja world would rise even more as he becomes more powerful under Kyuubi's tutelage.
In some fanfics, if Naruto becomes Kyuubi, he might gain incredible power. He could have enhanced physical abilities like super strength and speed. His appearance might also change, taking on more Kyuubi - like features. Maybe his eyes would turn red like the Kyuubi's, and he could have a more menacing aura. This transformation could make him a more feared and respected figure in the ninja world.
In this fanfic, Naruto might start by uniting the Uzumaki clan members. He could use his influence and power to bring back the glory of the clan. Maybe he'd focus on rediscovering lost Uzumaki jutsu and pass them on to the new generation.
Well, if Naruto thinks he's the Kyuubi in a fanfic, he would probably start to exhibit more of the Kyuubi's traits. He might become more aggressive and less patient. His appearance could also change, maybe having some Kyuubi - like features all the time. And his training would take a whole new turn, as he'd be trying to master the power he believes is his own, which is really the Kyuubi's.
The story could develop with Naruto becoming a villain of sorts. He might start attacking other villages or even his own, leading to a big conflict. His friends would then be on a mission to save him.
His friends from Konoha like Sakura and Shikamaru might support him. Sakura could offer her medical skills to help any ailing Uzumaki members, and Shikamaru could use his intelligence to strategize for the clan's growth.
