Obviously Naruto would be the main character. Sakura could potentially be part of his harem, as she has a long - standing relationship with Naruto in the original series. Hinata might also be there, given her deep feelings for Naruto.
In addition to the characters from Naruto's world, there could be new characters created specifically for this fanfiction. Maybe there could be a powerful sorceress who Naruto meets in the west and she becomes part of his harem. There could also be a strong warrior woman who is initially skeptical of Naruto but later falls for him.
The main character, the Duke of the West, is likely to be a strong and charismatic figure. Alongside him, Naruto himself might also be a significant character, perhaps as an ally or sometimes even a rival in terms of the relationships with the female characters. And of course, the female characters in the harem, who each have their own personalities, like the strong - willed Temari or the gentle Ino, are also main characters as they are central to the harem concept.
Obviously, Naruto would be one of the main characters. And since it's a harem - themed fanfiction, there would probably be several female characters, but without reading the specific fanfiction, it's hard to say who exactly they are.
Well, in this fanfiction, Naruto might face some ancient warriors who have been awakened for the tournament. These could be warriors with skills that have been long forgotten in the modern shinobi world. There could also be some ninja from clans that are exclusive to the western regions. These clans might have special abilities that Naruto has to figure out how to counter during the battles. And, there could be some foreign fighters who are not shinobi but have their own forms of combat that are equally challenging for Naruto.
Well, Naruto is the main one for sure. Then there might be some local heroes in the Western world who initially see Naruto as a threat but later become his friends. There could also be villains, like a power - hungry duke or a dark sorcerer who wants to stop Naruto from becoming the emperor. And don't forget about some common folk characters who Naruto tries to protect and win over.
Well, it could be about Naruto finding himself in a strange Western - like setting where he has a harem. Maybe he uses his ninja skills to protect his harem members from various threats in this new world.
Obviously Naruto is the main character since he is in the title. He is the one with godlike powers and the emperor of the west.
Most likely Naruto would be the main character as he is the Dragon Emperor. But other Naruto - verse characters might also be involved, like Sasuke, Sakura, Kakashi, etc. They could play different roles, such as Naruto's allies or opponents in this new storyline.
It could be one of the harem members who has a hidden dark side. Maybe she's jealous of Naruto's closeness to others in the harem and decides to turn the rest against him, so she becomes the main antagonist.
One potential ally could be the local peasants. Since Naruto is known for his kind heart, he would likely protect and support them. In return, they would support his rule. Another might be some of the local merchants. If Naruto promotes trade and economic growth, they would be on his side.
Sakura could be a potential member. She has been Naruto's friend and teammate for a long time, and in this fanfiction concept, her relationship with Naruto could evolve into a more romantic one within the harem. Her medical skills would also be an asset to the group.
