In fanfiction, Kurama is often depicted as calm, intelligent and elegant. His plant - based powers are usually a central part of the stories, whether he's using them for combat or for more peaceful purposes like healing. Yusuke, on the other hand, is usually portrayed as hot - headed but with a good heart. His impulsive nature gets him into trouble but also makes him a very dynamic character. He's also known for his strong fighting spirit.
To develop Hashirama's ghost, we could give him a sense of purpose. He could be a protector of the village in the afterlife. So, when he senses a great danger approaching the village, he decides to reach out to Naruto. He could have a deep connection to the natural world even as a ghost, and his powers could be related to manipulating nature spirits. He could teach Naruto how to communicate with these spirits and gain their assistance in times of need.
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.
Yes, unfortunately, Kurama passed away in the manga. This occurrence brought about a lot of changes and emotions for both the characters and the readers.
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.
