Kurama might be surprised. Since Naruto is just a toddler, Kurama may not expect such a small and seemingly harmless being to be his future host. He could be a bit more gentle in his initial reaction compared to when he first met older Naruto.
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.
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.
If we consider a fanfiction where toddler Naruto meets Kurama, it's a whole new world of possibilities. Toddler Naruto is likely to be more fearless and naive compared to his older self. He may not understand the danger that Kurama represents. Kurama, despite his tough exterior, could be taken aback by this small, fearless human. This meeting could result in Kurama having a soft spot for Naruto from the start. It might also lead to Naruto having some early access to Kurama's power, like being able to draw on a small amount of it unknowingly. This would make for a very different Naruto growing - up story in the fanfiction.
In some fanfictions, Naruto might summon Kurama through a new and special jutsu. For example, he could use a jutsu that combines his own chakra with the unique bond he has with Kurama. This jutsu might be created during a time of great need, like when facing an extremely powerful enemy that normal attacks can't defeat.
Kurama could comfort Naruto by sharing his own experiences. Since Kurama has been alive for a long time, he might tell Naruto about times when he faced difficult situations and how he overcame them. This could give Naruto new perspectives and the strength to keep going. For instance, Kurama could talk about how he endured his long imprisonment and still managed to keep his spirit intact, which in turn would inspire Naruto.
Often, Kurama gives Naruto an edge in combat. For example, in some fanfictions, Kurama can share his fox - like senses with Naruto, allowing Naruto to detect enemies from afar or sense hidden traps.
In certain fanfiction stories, Naruto bonds with Kurama when he defends Kurama from external threats. Imagine there are other forces trying to harm Kurama within the ninja world. Naruto stands up for Kurama, showing his loyalty. This act makes Kurama realize that Naruto truly cares about him, not just as a source of power, but as a friend. This realization cements their bond.
The characters' reactions would be complex. For instance, Iruka Sensei, who was like a father figure to Naruto, would be inconsolable. He has watched Naruto grow from a troublemaker to a hero, and this sacrifice would be too much to bear. Shikamaru, being Naruto's friend, would feel a mix of admiration and sadness. Admiration for Naruto's selfless act but sad that he's gone. The kids in the village who looked up to Naruto would be inspired in a way. They would want to be like Naruto and protect the things they love, even if it means sacrificing themselves.
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.
It could develop as Naruto spends more time in the mental space where Kurama resides. They start to communicate better, understand each other's motives, and gradually form a deeper connection. This might involve Naruto learning about Kurama's pain and loneliness over the years, which makes Kurama more open to Naruto. As a result, their bond becomes stronger and more symbiotic, allowing them to share power more effectively and support each other in different situations.
