The plot could be that a new enemy emerges who has the power to separate Naruto and Kyuubi. This makes both of them realize how much they have come to rely on each other. Naruto misses Kyuubi's strength and advice, and Kyuubi misses Naruto's positive energy. When they are finally reunited, they decide to be friends and fight side by side, with Naruto no longer just using Kyuubi's power but truly partnering with it.
One possible plot could be that Naruto starts having more conversations with Kyuubi in his mind. At first, they argue a lot as they have different views. But as time passes, Naruto starts to understand Kyuubi's past and the pain it has endured. Kyuubi, in turn, sees Naruto's determination and kindness. They gradually start to work together during battles, sharing their powers more effectively and eventually becoming true friends who trust and respect each other.
One possible plot could be that Naruto, in his journey to master his new form as the Kyuubi, seeks guidance from Kurenai. Kurenai, with her knowledge of genjutsu and combat experience, could train Naruto to control the wild power of the Kyuubi within him. This would involve Naruto facing internal struggles as the Kyuubi's instincts clash with his own values. Along the way, they might face common enemies who are interested in Naruto's new power or want to use it for their own evil purposes.
Well, their friendship develops through Naruto's determination. He doesn't see the Kyuubi as just a source of power. Instead, he tries to understand it. Naruto's positive attitude gradually breaks down the Kyuubi's initial hostility. As time goes by, they start to communicate more, and Naruto shows the Kyuubi that he respects it as an individual. This mutual understanding forms the basis of their friendship.
One interesting plot could be that Kurama has a hidden past related to the creation of the ninja world. As Naruto and Kurama become friends, Kurama reveals this past. It could involve ancient ninja clans and forgotten jutsus. Naruto then uses this knowledge, along with Kurama's power, to bring about a new era of peace in the ninja world.
One memorable moment is when Naruto first convinces the Kyuubi to lend him some of its power without forcing it. It shows that their relationship has reached a new level of trust. Another moment is when they work together to defeat a particularly strong enemy. They combine their strength and willpower, and it's a display of their strong friendship. Also, the times when Naruto just sits and talks to the Kyuubi about his day or his problems are quite memorable as it shows their growing bond.
A 'naruto ganbanged kyuubi fanfic' could potentially be about Naruto and the Nine - Tails (Kyuubi) forming an unexpected and deep bond. Maybe Naruto discovers new powers within the Kyuubi that no one else knew about, and they work together to face new threats in the ninja world. This could involve Naruto learning to control the Kyuubi's power in a more refined way and using it to protect his village in unique ways.
The plot might involve Naruto entering the Kyuubi's mental space in a new and more powerful way. He could bring with him some sort of 'light' or positive energy that is anathema to the Kyuubi. This positive energy could represent all the good things in Naruto's life, like his friends, his dreams, and his love for the village. The Kyuubi, being a creature of darkness and power, is scared by this pure and positive force. Or maybe Naruto discovers a hidden weakness of the Kyuubi through his own growth and understanding. He then exploits this weakness, causing the Kyuubi to be afraid of what Naruto could do to it.
Well, it could be about Naruto learning unique combat techniques directly from the Kyuubi. The Kyuubi, being a powerful and ancient entity, might teach Naruto some forgotten or forbidden jutsu. This would set Naruto apart from his original training path in the canon series. Maybe he'd learn how to use the Kyuubi's chakra in a more controlled and strategic way, like creating chakra shields or new types of elemental attacks.
The plot could involve Naruto being turned into Kyuubi's daughter as part of a plot by an evil ninja. In this situation, Naruto would first be confused and scared. But as he gets used to his new form, he starts to explore the benefits. Maybe he can now communicate with other fox - like creatures in the forest. He uses this to his advantage to gather information about the enemy. Also, his relationships with his friends would change. Sakura might be a bit shocked at first, but she would soon accept him and help him figure out how to use his new powers for good. Naruto would also have to face the Kyuubi in a different way, now that he has a more personal connection to it.
One idea could be Naruto fully embracing the Kyuubi's power and using it in unique ways. For example, he might be able to transform into a new, more powerful form that combines his own skills with the raw power of the Kyuubi. He could also use the Kyuubi's chakra to perform new jutsus that are previously unthinkable. Another plot idea is that Naruto starts to think and act more like the Kyuubi in some aspects, which causes conflict among his friends and allies as they try to figure out if he's still the same Naruto they know.
His character could become more mature. Since Kyuubi has a lot of knowledge and experience, Naruto would learn from it. He would be less impulsive and think more before acting. Their friendship would also make Naruto more understanding of the darker aspects of life, as Kyuubi has seen a lot of pain and destruction. This new understanding would shape him into a more well - rounded and wiser ninja.
