I'm not sure specifically as there could be many different interpretations in such a fanfic. It might involve Naruto in an imperial - like role, perhaps ruling a kingdom or having a lot of power and influence in a made - up imperial setting.
Power is a common theme. Since Naruto is in an 'emperor' role, it often focuses on how he wields power, whether it's political power over Konoha or his ninja powers in a new context.
Perhaps Naruto discovers some ancient power or prophecy that makes him the rightful emperor. He then has to deal with the political intrigue within the ninja world. Some might oppose his rule, thinking he's too young or inexperienced, while others see him as the savior. He'd have to build his court, choose his advisors, and face external threats from other lands that see a united ninja world as a threat.
Well, one possibility could be that Naruto, as the emperor, uses his ninja skills to bring peace and prosperity to his empire. He might use his shadow clone jutsu to be in multiple places at once, like overseeing different regions or handling various diplomatic meetings.
I haven't read this specific 'Dark Naruto Emperor of West Fanfic' in detail. But generally, in fanfics like this, the character of Naruto might be given a darker or more complex twist. It could explore different power dynamics and relationships within the Naruto universe.
Obviously, his old friends like Sakura would be his allies. Sakura, with her medical ninja skills, could be in charge of the healthcare system in Naruto's empire. And Kakashi could be an important military advisor, given his vast combat experience.
Perhaps in this 'emperor naruto avatar fanfic', Naruto is made emperor due to his heroic deeds in both worlds. As emperor, he has to deal with political intrigue. He might have to form alliances with different clans from the Naruto world and different tribes from the Avatar world. His friends from both universes would help him, like Sasuke and Aang. They could teach each other their unique skills and fight against common enemies who oppose Naruto's new rule.
Maybe. It could be that Naruto discovers he's not really an emperor by right but was tricked into the role. Or perhaps his closest ally turns out to be a traitor plotting to overthrow him.
There could be new characters created specifically for this fanfic. For instance, some powerful advisors or generals in Naruto's 'emperor' regime. These characters could have their own motives and backstories that interact with Naruto's journey. They might be helping him build his empire or secretly plotting against him.
If Naruto is the Sith Emperor in a fanfic, it would likely change the whole dynamic of the Star Wars universe. His backstory as an outcast in the ninja world could parallel the Sith's view of being outsiders in the Jedi - dominated galaxy. He might introduce new training methods for Sith apprentices, based on his own experiences growing up in Konoha. And his relationships with other Star Wars characters would be fascinating. Would he see Darth Vader as a kindred spirit? Or would he try to outdo Palpatine in terms of power and influence?
