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.
A possible plotline could be Naruto characters being transported to a Lyon - like world that has an 'empire' structure. They might have to navigate the politics and power struggles within this new empire. Another could be that an 'empire' in the Naruto universe is influenced by Lyon - style culture and architecture, leading to new challenges and adventures for the characters.
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.
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.
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.
It could be some of the well - known characters from 'The Empire' who take on new roles in the context of the Glee club. Maybe Lucious Lyon could be one, bringing his strong - willed and often controlling personality into the club and causing some chaos.
There could be a powerful dark lord as a main character. He might be the one ruling the empire with an iron fist.
Often, there's the powerful Emperor who rules the Dark Empire with an iron fist. His presence is felt throughout the story as he makes crucial decisions for the empire.
I'm not sure specifically as it depends on the particular fanfiction. But usually, there would be a strong leader figure, perhaps a military general or a political leader who guides the empire. There might also be a rebel or an outsider who challenges the status quo of the empire.
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.
