There could be a really interesting fanfiction where the worlds of RWBY and Naruto collide with Kurama in it. Maybe Ruby could meet Naruto and they both have to deal with some sort of fading magic or power related to Kurama. It could be that Kurama's chakra is fading and it's affecting both universes in strange ways.
One way could be through a dimensional rift. Imagine Kurama's power is fading in the Naruto world due to some dark magic. This rift opens up and connects to the RWBY world. Ruby, being the curious and adventurous type, jumps through. She meets Naruto and they realize that the fading of Kurama's power is somehow tied to a similar fading of magic in RWBY. They have to find a way to reverse it.
In a fanfiction, imagine a scenario where Naruto loses control of Kurama during a battle, and Gaara is the only one who can calm him down. Gaara uses his own experiences with his tailed beast to reach out to Naruto and Kurama. This could lead to a deeper understanding between the three characters and a strengthening of their bonds.
A great Naruto and RWBY fanfiction idea involving foxes could be that there is a hidden clan in RWBY that has the ability to transform into foxes, similar to the transformation jutsu in Naruto. When Naruto characters visit RWBY's world, they discover this clan and learn about their unique abilities. In return, they teach the clan some of their ninja techniques.
One unique way to develop their relationship is through art. In the fanfiction, Naruto could have the ability to draw out Kurama's chakra in a new form using his own creativity. This would be a new way of interacting that combines Naruto's love for art and his connection to Kurama. As they explore this new form of chakra manipulation together, their bond deepens.
The Kurama Brothers could be entities that have a similar origin to Kurama. They might have been part of the same chakra - based creation in the Naruto universe. They could possess some of Kurama's traits like great power and a connection to the natural energy in the world. They are often depicted as having their own personalities, with one being more hot - headed and the other more calm and calculating. Their relationship with Naruto usually involves them using their powers and knowledge to help Naruto grow as a ninja and a person. They might also have their own goals and motives that are intertwined with Naruto's journey.
Well, Kurama might train Naruto by teaching him how to better control and access chakra. Since Kurama has a vast amount of chakra, it could show Naruto unique ways to harness and use it. For example, it could guide Naruto in creating more powerful and complex jutsu by using their combined chakra in a more efficient way.
Kurama might become angry at first. He's a powerful being and being neglected would likely wound his pride. He could start causing some minor disruptions inside Naruto, like making it harder for Naruto to access his chakra.
It might be portrayed as a very strong and almost spiritual connection. They could be shown as two halves of a whole, with Naruto relying on Kurama not just for power but also for emotional support and vice versa.
One way is through shared experiences. For example, they could go on a journey together outside the village. During this journey, they face challenges like bad weather, lack of food, and dangerous animals. As they overcome these challenges together, their bond grows stronger. Also, Naruto could introduce Kurama to his friends, and Kurama could learn to interact with humans in a more friendly way. This would show that their relationship is not just about being sealed together but about true friendship.
Naruto's self - confidence gets a huge boost. Kurama's teachings are like a seal of approval. If Kurama believes in him enough to teach him, then Naruto must be something special. This new - found confidence shows in his posture, his speech, and how he faces challenges. He no longer doubts himself as much when it comes to difficult tasks, whether it's a tough battle or a diplomatic negotiation within the ninja world.
