Rock Lee could be a great ally. He has always admired Naruto's spirit. In a 'Naruto banished new village' scenario, he might choose to follow Naruto, believing in Naruto's vision for a new and better village. Additionally, some of the foreign ninjas that Naruto has befriended during his adventures could also become his allies. They could bring in different cultures and ninja techniques, enriching the new village. And don't forget about the summons, like the toads. They might also support Naruto in building his new village as they have a special bond with him.
The Jinchuriki from other villages could be potential allies. Since Naruto has a unique understanding of what it means to be a Jinchuriki, they might be drawn to his new village. They could share their own experiences and powers, creating a powerful group within the new village. Also, the orphans and those who have been mistreated in their own villages might flock to Naruto's new village. They would see Naruto as a symbol of hope and a chance for a new beginning, and thus become his loyal allies.
Sasuke could be an ally. Despite their past differences, Sasuke might see the injustice of Naruto's banishment and decide to join him. He could bring his powerful Sharingan skills to the new village. Also, some of Naruto's old friends like Shikamaru or Choji might secretly support him and provide resources or information. They could be like undercover allies still within the old village but helping Naruto's new village in various ways.
If Naruto is banished to the My Hero Academia universe, Deku could be his ally. Deku, with his determination to be a hero, would understand Naruto's drive to be recognized. They could share their experiences of being underestimated at first. Also, in a crossover with the Inuyasha world, Kagome could be an ally. She has a kind heart and could help Naruto understand the new world he's in. Her spiritual powers might also interact in an interesting way with Naruto's chakra.
In this type of fanfiction, Naruto could be banished because of a conspiracy within the village. When he starts his new village, he may attract ninjas who are tired of the old - fashioned and corrupt ways of the existing villages. His new village could be a haven for those who want to practice their ninjutsu freely and without judgment. He might also establish a unique training system that combines his own experiences and the skills he learned from different masters, creating a new generation of powerful and morally upright ninjas.
Sasuke could be one of his allies. Despite their past differences, Sasuke might see Naruto's new path as a way to create a better world. He could offer his combat skills and strategic mind to help Naruto rule. Another ally could be Hinata. She has always been supportive of Naruto, and as emperor, Naruto would need someone he can trust, and Hinata fits that role perfectly.
There are also the wandering ninja. These are ninja who don't belong to any particular village. They might join forces with Naruto because they understand what it's like to be on the outside. Together, they could form a sort of 'rogue' ninja group.
Rock Lee could be an important ally as well. His unwavering determination and physical strength would be useful for the heavy - lifting tasks involved in building the village, like constructing buildings and fortifications. Also, his positive attitude would inspire the other villagers to work hard towards making the new village a success.
It could be the ninja from Naruto's former village who don't want him to succeed in his new place. They might see his new - found influence as a threat and try to undermine him.
Sasuke could be a likely ally. Despite their past differences, Sasuke might see the injustice in Naruto and Shikamaru's banishment and decide to help them. He has his own reasons to oppose the village's wrongdoings at times.
Naruto could potentially be allied with those who oppose the traditional power structure of the ninja world, not just limited to specific villages. There might be a group of ninja who believe in a more equal and just ninja world without the dominance of the big five villages. He could also form an alliance with some mysterious and powerful individuals who have their own agendas and see Naruto as a useful tool outside of the Konoha context.
Well, one possibility is that Naruto, after being banished, finds a small, struggling village. He brings his unique skills and determination there. Maybe he helps them improve their defenses against other threats in the ninja world. He could also train the local ninja, sharing his knowledge of powerful jutsu.
Aang could be an ally. Since Aang was the previous avatar, he could guide Naruto in understanding the avatar state and how to use it effectively. Katara could also be an ally. She could teach Naruto water - bending techniques and help him with his emotional side as she's very empathetic.
