Well, it could be about a Naruto who has god - like powers and gets banished. Maybe he's too powerful for the village to handle, or perhaps there are some political reasons within the village that lead to his banishment. But without reading it, it's hard to say exactly.
Perhaps it reveals secrets about Naruto's family that were previously unknown. For example, there might be a connection to an ancient clan that was banished from the village long ago, and this fanfic explores how that heritage affects Naruto's character and abilities. It could also show some unique powers or items that are passed down through his banished heritage.
In a 'Naruto banished by Sarutobi' fanfic, the plot might revolve around political intrigue within the village. There could be a group that convinces Sarutobi to banish Naruto for their own gains. Naruto, being banished, would likely set out on a journey of self - discovery. He'd meet new allies and foes. He might even discover new powers or lineages that were hidden from him while he was in the village. And all the while, he'd be thinking about getting back to Konoha to clear his name.
Well, without having read it, it could involve Naruto being sent away from his home, perhaps Konoha, and then rising to power in the west. Maybe he has to face new enemies, form new alliances, and deal with the politics and power struggles in that region. It could also explore how his ninja skills are adapted to this new situation and how his relationships with other characters change.
Another theme is adaptation. He has to adapt to the new rules, cultures, and powers of the crossover world. For example, if it's a crossover with a magic - based world, Naruto has to learn how magic works and how to use it. This theme of adaptation makes for some interesting character development.
A 'Naruto get banished yaoi fanfic' is likely about Naruto being exiled from his village and then there are probably yaoi elements involved, which means male - male relationships. It could be about Naruto forming new relationships with other male characters during his exile.
Well, Naruto himself could be a really interesting take on a banished prodigy. Imagine if things had gone differently in the village and he was banished. It would be a huge change from the original story. Shikamaru is also a possibility. He's intelligent and has a lot of potential. If there was some sort of political or power struggle within the village that led to his banishment, it could make for an engaging fanfic. Also, Hinata could be a unique choice. Her shy nature but hidden strength could be explored in a banished prodigy storyline.
It could be that they are wrongly accused of a crime they didn't commit. Maybe a major incident occurs in the village and they are made scapegoats. So, they are banished as a result of this false blame.
In this kind of fanfic, Naruto's character development would be significant. Initially, he'd be full of anger and resentment towards Sarutobi and Konoha. But as he faces the challenges of the outside world, he realizes that there are bigger issues at play. His experience outside the village would make him more empathetic towards those who are also ostracized. He'd become a more well - rounded character, not just a loud - mouthed ninja from Konoha. His relationships with others would change too. He'd form deeper bonds with those who accept him during his exile, and these relationships would shape his future actions and decisions. He might also start to question the whole ninja system, which could lead to him trying to change it when he has the chance to return to Konoha.
