We can only guess. It's possible that the main characters are a mix of well - known Naruto characters and new ones created to fit the Jin Dynasty theme. For instance, a character from the Jin Dynasty could be brought into the Naruto world and have a significant impact on Naruto and his friends. Or Naruto could be reincarnated as a figure from the Jin Dynasty's history, and that reincarnated form could be one of the main characters in this fanfic.
I don't know specifically as I haven't read it. But it could include Naruto himself, along with some of his friends like Sasuke or Sakura. Maybe there are also characters inspired by historical figures from the Jin Dynasty.
I'm not entirely sure as it's a fanfic. But it might combine elements of the Naruto universe with the Jin Dynasty in some creative ways, perhaps having Naruto characters interact with the historical context, cultures or events related to the Jin Dynasty.
Often, the main characters can be the descendants of the original Naruto characters. So, we might see Naruto and Hinata's son or daughter as a main character, carrying on the Uzumaki legacy.
Since I haven't read it, I'm not sure. But it could be Naruto characters like Naruto himself, Sasuke, or Sakura who are somehow connected to the legacies of Athena and Hermes.
Often, the descendants of the original Naruto characters are main characters. For example, Naruto and Hinata's son, Boruto, might be a central figure.
I don't have enough information to know the main characters in 'legacy undone fanfic'. It could be original characters created for the fanfic or well - known characters from the original work that the fanfic is based on.
In addition to Naruto's family, his old friends such as Sasuke could also be main characters. Sasuke might be involved in trying to find a way to break Naruto's seal or protecting the village in Naruto's absence. Other characters like Kakashi, who has a long - standing relationship with Naruto, could also be important in this fanfiction.
The main characters in 'Naruto Legacy of the 7 Swordsmen Fanfiction' are most definitely the 7 Swordsmen. These are characters who have a long and storied history in the Naruto universe. Their swords are not just weapons but symbols of their power and status. Additionally, there could be new characters introduced in the fanfiction that are related to the 7 Swordsmen in some way, perhaps descendants or students. And of course, we can't rule out the appearance of some of the main Naruto protagonists like Naruto Uzumaki, who might get involved in the affairs of the 7 Swordsmen for various reasons such as to protect the village or seek knowledge about their powers.
It's hard to say for sure without reading it, but it could be Naruto and his friends. They are the main characters in the original series, so it's likely they'll play important roles in this fanfiction as well, perhaps trying to combat the chaos.
Well, if it follows the Naruto series closely, Naruto himself could be a main character. He might be the one to bridge the gap between the Naruto world and the Legacy of Kain elements. Sasuke could also be there, as he often plays a major role in Naruto - related stories. But it could also introduce new characters inspired by Legacy of Kain.
Obviously, Madara himself is a main character. He is the center of the story's legacy aspect. Naruto might also be a main character as he often represents the new generation and the hope for change in the Naruto universe. He could be the one to either oppose or understand Madara's legacy in the fanfiction.
