Definitely. Besides Naruto, other characters from the original series could have new roles. For instance, Sasuke could be a sort of rebel within the empire, challenging Naruto's rule in some ways while also having his own reasons for doing so. And then there could be characters from other villages who interact with the Naruto empire in different ways, like trying to form alliances or plotting against it.
Typically, Naruto is likely to be a central figure. Alongside him, there could be a noble from the Lyon Empire who is intrigued by Naruto's powers and tries to learn from him. There may also be a ninja from Naruto's village who accompanies him to the Lyon Empire and has to adapt to the new environment. In some fanfictions, there could be a powerful mage or warrior from the Lyon Empire who challenges Naruto and his ninja ways.
Obviously, Naruto is one of the main characters. In the context of this fanfiction, he is the one who gets involved with the Alvarez Empire.
There could be new characters introduced specific to the Eternal Empire. Maybe a powerful emperor or empress who rules the empire and has their own motives and secrets. These new characters would interact with Naruto and the existing cast, creating new dynamics and storylines.
Obviously Naruto himself is the central character. His friends like Sasuke could also be important. Sasuke might be Naruto's right - hand man, using his Sharingan abilities to help Naruto in various aspects, such as intelligence - gathering or combat. Sakura could be in charge of the medical aspects of the empire, given her skills as a medical ninja. And Kakashi could serve as an advisor, sharing his wisdom and experience.
There might not be a huge number of fanfictions that combine 'empire', 'naruto' and are related to Lyon directly. However, if you look at broader concepts in Naruto that could be related to an 'empire' - like the Hidden Villages being a sort of mini - empires in a way. And as for the Lyon part, perhaps it could be a setting where the characters from Naruto are re - imagined in a Lyon - esque environment in a very creative fanfiction. You should also consider reaching out to Naruto fan communities on social media to ask if anyone knows of such fanfictions.
Yes, there might be. Since it's a fanfiction, new characters could be introduced. They could be unique in their abilities, like having a power that's a combination of different ninja techniques. Or perhaps there are characters who are trying to fix the shattered world, with strong leadership qualities.
Yes, there are quite a few. Some fanfictions might blend the magic systems of both. For example, a story could have a character from 'Jade Empire' end up in the 'Harry Potter' world and learn about magic there in a different way. They might introduce martial arts - based magic from 'Jade Empire' into Hogwarts.
One interesting concept could be the unique blend of Naruto's ninja world with the elements of the Lyon Empire. For example, how the ninja skills might interact with the political and cultural aspects of the empire. Maybe ninjas could be used as special agents within the empire's power structure.
Character interactions are a big draw. Picture Naruto himself interacting with an emperor or empress from the other empire. Their different values and goals would surely lead to some intense and thought - provoking dialogues, and perhaps even a change in Naruto's view of leadership.
One interesting story could be about Naruto joining the Alvarez Empire and having to adapt to their different culture and ways of doing things. Maybe he has to prove himself in their combat trials.
