In addition, there could be new characters created specifically for this fanfic. These new characters might be students or followers of the Kage Fujin, or they could be antagonists who oppose the Kage Fujin's plans for the ninja world. Their backstories and relationships with the other characters would add depth to the story.
The Kage Fujin is likely to be one of the main characters. They are probably a powerful figure with unique abilities related to the elements or some other special power.
There might also be other well - known Naruto characters like Naruto himself or Sasuke. They could be either allies or rivals to the Kage Fujin. For example, Naruto might be a source of inspiration for the Kage Fujin's journey to protect the ninja world, or Sasuke could be a character who challenges the Kage Fujin's beliefs and actions.
In a 'naruto wave kage fanfic', Naruto is almost always a main character due to his significance in the Naruto universe. The Kage are also central as they represent the leadership of their respective villages. The Wave Village might introduce characters like Tazuna or Inari as main characters too. Tazuna was important in the original Wave arc in Naruto. His skills as a bridge - builder could play a different role in the fanfic, like being a symbol of hope for the Wave Village in a time of conflict involving the Kage. Inari, with his growth and potential, could also have a major part in the story, perhaps forming an unexpected bond with one of the Kage.
One interesting plot could be the exploration of new jutsu by the Kage Fujin. Maybe they develop a unique way to combine different elemental chakra in a never - before - seen manner.
Obviously, Naruto is usually one of the main characters. And Fujin, of course. In many cases, Sasuke might also be involved as he is an important part of the Naruto universe. His rivalry or friendship with Naruto can add more depth to the story in the fanfic.
The Hokage, like Tsunade or Kakashi, could be the ones training Naruto. They know Naruto well and have a lot of knowledge and skills to pass on.
A new, young ninja from a minor village could be the main character. They could be trying to make a name for themselves and their village at the Kage Summit. They might get involved in some political intrigue or even a fight between the Kages and prove their worth.
Naruto himself could still be the main character, but this time showing even more advanced kage - level skills. Maybe he's facing a threat that only his new and improved abilities can handle.
Obviously Naruto is one of the main characters. Since it's related to the Chunin Exams, his friends like Sasuke and Sakura are likely to be important as well. And the kage who is involved in the story would also be a main character, as they play a crucial role in Naruto's journey during the exams.
The Kages themselves are often main characters. For example, Tsunade from Konoha, Gaara from Suna, and the other village leaders. They play important roles in the political and power - related discussions during the summit.
It could be Naruto himself. Since he has a connection to all the villages in some way, he could play a crucial role in the fanfic, perhaps as a mediator or someone who uncovers a hidden conspiracy during the summit.
Sasuke could be a great main character. He has the power and the complex backstory. If he became the Kage of a different village, say the Mist Village, he could use his Sharingan and his combat skills to change the village's fate. He might try to end the long - standing blood feuds within the village using his own experiences of revenge and redemption.
