In this fanfiction, apart from Naruto's usual comrades, there could be new characters. Maybe some descendants of ancient ninja clans that were once forgotten come forward to support Naruto's cause. Characters like Shikamaru would still play a role, probably as a strategist for the empire. And Hinata might be involved in diplomatic relations, using her gentle yet firm nature to negotiate with other regions. Also, the Akatsuki members who have reformed could be part of Naruto's new empire, contributing their unique skills.
Well, Naruto would be the main character, no doubt. But we could also see the return of some older characters who might have been thought dead. For example, Itachi could come back in some form and use his knowledge of the ninja world and his powerful jutsu to help Naruto build the empire. Jiraiya could also be a guiding spirit, with Naruto remembering his teachings and applying them to his empire - building. And Tenten could be in charge of weapon development and management within the empire, given her expertise with various weapons.
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.
Well, it could be about Naruto using his unique skills and charisma to gather allies from different villages. He might start by reforming Konoha, making it a more inclusive and prosperous place. Then, with his newfound power and influence, he could expand his reach to other lands, gradually building an empire where all ninja can co - exist peacefully.
Sakura could be one of her main allies. Sakura, with her medical skills, would be invaluable in taking care of the injured in Fem Naruto's growing empire. Also, Shikamaru, with his intelligence, could help in strategic planning and dealing with political matters.
Well, Naruto building the Sith Empire is a wild concept. He might be influenced by a powerful Sith artifact. Imagine he finds a Sith Holocron that shows him visions of great power. His own desire to protect his friends could be twisted. He might think that by ruling through the Sith Empire, he could ensure their safety. He'd then use his charisma, which he had in his own world, to gather people to his cause in the Star Wars universe.
One possible plot could be that Fem Naruto, with her unique skills and charisma, starts by uniting a small group of outcasts. She uses her ninjutsu in new and creative ways to protect them and gain resources. As time goes on, she attracts more and more people, gradually building a small village that evolves into an empire. She might face opposition from traditional ninja villages who see her as a threat.
Ino could be part of the harem. She is a confident and skilled kunoichi. Karin might also be in it, especially considering her past interactions with Naruto. And then there's Tsunade. Although she is much older, in some fanfictions, her relationship with Naruto can take on a different, more romantic or mentorship - turned - romantic angle.
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.
The main characters would be Naruto and his friends from the Leaf Village. But in Halloween Town, we could see some characters inspired by classic Halloween figures. There could be a Jack - o' - lantern - headed merchant who sells strange items. A mummy - like ninja who is very slow but has incredible strength. And a ghostly figure who was once a great ninja but got trapped in Halloween Town and now gives Naruto advice on how to defeat the forces that lurk in the shadows of the town.
In this fanfiction, characters like Hagrid could also be involved. He could befriend Naruto and introduce him to the more positive aspects of the wizarding world. And of course, there could be other Death Eaters who might either try to use Naruto or see him as a threat due to his relation to Bellatrix.
