Perhaps Naruto discovers some hidden resources in the area around Ushiogakure. With these resources, he is able to build new infrastructure like training grounds and housing. He also invites friendly ninja clans to settle there, bringing in new blood and skills. As a result, Ushiogakure slowly but surely becomes a prosperous village.
Naruto might focus on education in Ushiogakure. He could set up a ninja academy similar to the one in Konoha. He would teach the students about the importance of unity and hard work. By training a new generation of ninjas with a different mindset, Ushiogakure can be rebuilt into a village that values cooperation and innovation.
One big challenge would be finding skilled ninjas to help him. Ushiogakure might not have a large population to start with. He'd need to either train new ninjas from scratch or convince others to join him. Another issue could be dealing with any existing rivalries or feuds in the area.
One possible plotline could be Naruto using his newfound freedom away from Konoha to search for remnants of Uzushiogakure. He might discover hidden scrolls or techniques that were once used in Uzushiogakure. Then, with his determination and the help of some friends he makes along the way, like other outcasts or those interested in the lost village, he starts to rebuild it bit by bit. Maybe he first focuses on building a small community center where people can gather and learn about the history of Uzushiogakure.
Naruto might start off as an outcast in the banished Kingdom Hearts world, much like he was in his own village at times. But his skills would soon draw the attention of the locals. He could use his speed and agility to dodge attacks from the strange creatures in this world, like Nobodies. And his ability to sense danger, which he developed in the Naruto world, would be a great asset here.
In this fanfiction, Naruto might be banished due to false accusations. When he starts his village, he could attract other shinobi who were also wrongly treated in their own villages. They would bring with them different techniques and cultures. Naruto's village could then become a place of innovation in ninjutsu. For example, they might combine different elemental jutsus in new ways. The village would also have a strict code of honor that values truth and loyalty above all, as Naruto has always been a symbol of those values.
Well, in this fanfiction, perhaps Naruto's banishment leads to him exploring different ninja techniques from other lands. He could combine these with his own skills, like his shadow clone jutsu, to create something entirely new and powerful. It could also show how he overcomes the stigma of being banished and rises above it.
Well, one idea could be that Naruto discovers a new way to use his Mokuton abilities while in exile. Maybe he meets some unique characters who help him master it further.
Maybe Naruto's connection to Pein through the Nine - Tails is misinterpreted. Since Pein was after the Nine - Tails, the village believes Naruto is a liability. Banished, Naruto wanders into a hidden land where he learns ancient ninja techniques that are far more powerful than what he knew. He could then return to the village as a changed and more powerful ninja, but with a sense of bitterness towards those who banished him.
One idea could be that Naruto, after being banished, is found by Itachi in a desolate place. Itachi, seeing Naruto's potential and his own complex feelings towards Konoha, decides to train Naruto in secret. This could lead to Naruto developing new and unique jutsu under Itachi's guidance, and perhaps they form an unlikely alliance against a common enemy.
Well, in some of these fanfictions, one interesting idea could be the political implications of Samui being banished. It might create a rift between different ninja clans or villages. Maybe her banishment is a result of a false accusation, which then leads to Naruto getting involved to clear her name. This could set off a chain of events that includes new alliances and battles.
Well, in 'Naruto Banished Assassin' fanfiction, often there's the idea of the assassin forming unexpected alliances. Since they are banished, they might team up with former enemies or other outcasts. This could lead to some really cool story arcs where they work together to take on common foes or even change the shinobi world in some way. Also, their internal struggle between their former loyalty to the village and their new situation as a banished person is quite engaging.
