Perhaps in this fanfiction, Naruto as a fox discovers a hidden part of the forest that has a special connection to the Nine - Tails. He could then have to protect this area from those who want to use its power for evil, leading to some intense battles and moral dilemmas.
It could be that Naruto in his fox form befriends other forest animals in a more natural way than he could as a human. This friendship then helps him in his journey, like when the animals alert him to approaching danger or help him find rare herbs for healing.
One possible interesting plot could be Naruto using his fox form to outwit enemies in a way he couldn't as a human. For example, he might be able to use his natural fox agility to escape traps more easily.
One possible plot could be that Naruto, as a fox, has to navigate the Hidden Leaf Village in a new form. He might struggle to communicate with his friends at first, but then discovers new ways to convey his thoughts, like through telepathy. Another idea is that he uses his new fox form to explore areas of the forest that were previously off - limits to him as a human. This could lead to him finding ancient secrets or new forms of chakra.
Well, one interesting plot could be Naruto having to rely on his friends in a whole new way as a baby fox. Since he can't communicate as he used to, his friends have to figure out his needs through his actions. Another plot might be that Naruto discovers new abilities or powers in his baby fox form that he didn't know he had before.
In a female Naruto fox Kyuubi fanfiction, a great plot could be her having to prove herself to the village. Since she's female and has this connection to the Kyuubi, some villagers might be more skeptical or even afraid of her. She then has to go on a journey to show that she can control the Kyuubi's power and use it for good. Along the way, she meets other characters who either help or hinder her progress. And she might also discover secrets about the Kyuubi's origin that no one in the village knew before.
Well, in some fanfictions, the fox god could be a mentor to Inari. It could teach Inari about ancient ninja arts that were long forgotten. This would not only enhance Inari's skills but also make him a more important figure in the Naruto universe. He could then use these skills to face off against new and dangerous enemies.
One interesting plot is when the Kyuubi can communicate with Naruto's friends in a 'Fox Naruto Kyuubi' fanfiction. It creates a whole new dynamic as the friends have to deal with the powerful and often grumpy Kyuubi. Another plot is the Kyuubi being able to take a physical form outside of Naruto and having its own adventures while still being linked to Naruto. It's really cool to see the Kyuubi interact with the ninja world on its own terms.
One interesting plot could be Naruto fully transforming into the Nine - Tailed Fox during a battle against a powerful enemy. His friends are initially shocked but then try to find a way to bring him back to his senses.
One possible plot could be that Naruto, in his fox - like form, senses a danger approaching Hinata. He uses his enhanced speed and strength to stand guard over her. For example, a powerful enemy from another land has targeted Hinata for her special Byakugan abilities. Naruto, with his fox - like instincts, is able to detect the enemy's hidden approach long before Hinata realizes the danger. He then battles the enemy, using his fox - powered attacks to keep Hinata safe.
Another plot could involve the female Naruto using the power of the Ten - Tailed Fox to protect her village in a different way. Since she is female, her approach might be more nurturing. She could use the fox's power to heal the land around the village that has been damaged by previous battles. This would show a different side of the power of the Ten - Tailed Fox, not just as a destructive force but also as a force for renewal.
In some fanfictions, Naruto's lost memories and the fox are related to an ancient prophecy. The story could be that Naruto was meant to forget his past life as part of a grand plan to defeat a great evil. The fox, being a powerful and mysterious entity, has its own motives in all this. It might be trying to guide Naruto in a certain direction while he's clueless about his identity. His friends notice his strange behavior and start to investigate. Along the way, they uncover secrets about Naruto's past that even he didn't know, and the fox is at the center of it all, holding the key to his true self and the future of the ninja world.
One interesting plot could be Naruto's struggle to control the power of the Nine - Tailed Fox when he releases it. He might have to face inner demons and the fear of losing himself to the fox's power.
