The tailed beasts could be his allies. Since Naruto has a connection with them, they could work together with Naruto in his role as the King of Monsters. For example, they could combine their powers to create a formidable force against any threats to the ninja world.
Sasuke could be one of his main allies. Despite their past differences, they could put aside their issues to support Naruto in his role as the King of Monsters. Sasuke's powerful combat skills would be a great asset in battles against those who oppose Naruto.
Kakashi could also be an ally. His experience and wisdom would be valuable in guiding Naruto on how to use his new powers as the King of Monsters responsibly. He could also help Naruto in strategizing during conflicts.
Definitely the Na'vi. They are the native inhabitants of Pandora and would likely see Naruto as an ally, especially if he shows respect for their land and culture. His skills could be useful to them in their fight against any common enemies.
Some of the lesser - known Ame ninjas who are tired of the constant conflict. They might see Naruto as a symbol of change and ally with him. These ninjas could have unique skills that Naruto can learn from, and together they can work towards a more positive future for Ame.
The other members of Team 7 like Sakura and Kakashi could also be his allies. Sakura could use her medical ninjutsu to heal any injuries Naruto and the team get in space battles. Kakashi could offer his wisdom and combat experience, guiding Naruto in this new and unfamiliar space - filled adventure.
Sasuke could potentially be an ally. Even though they have their differences, in the Akatsuki setting, they might realize they need to work together. Another could be Itachi. Itachi has his own motives and might see Naruto as a key to achieving certain goals within the Akatsuki. Also, Konan could be an ally. She seems to be more open - minded compared to some of the other members and might be swayed by Naruto's positive attitude.
Sasuke could be one of his allies. He might be a rival knight at first but then they realize they have to work together. Sakura could be a healer knight, always there to patch up Naruto and the others after battles. Kakashi could be a wise old knight who gives Naruto advice on knightly matters.
Naruto's allies could include not only his friends from Konoha but also some unexpected characters. Maybe Gaara, as the Kazekage, would form an alliance with Naruto's empire. Their shared experiences of being outcasts in the past could strengthen their bond. Hinata would also be by his side, offering her gentle support and her Byakugan abilities to help in matters of security and intelligence - gathering within the empire.
Sakura could be one of his allies. Even in a sorcerer - themed fanfiction, her medical skills could be translated into some sort of healing magic within the sorcerer world, and she would always be by Naruto's side.
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.
Definitely, the Akatsuki members who have reformed could be potential allies. They have unique powers and knowledge of the ninja world. Naruto's ability to see the good in people might lead him to recruit some of them. Additionally, the toads from Mount Myoboku could be allies, providing their prophetic knowledge and combat support when needed. And, of course, his old friends from Konoha like Kiba and Choji would come to his aid if the situation called for it.
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.
