In this type of fanfiction, Naruto could find an ally in Anko. She is a bit of a wild card but she has a strong sense of justice. His power might intrigue her and she could team up with him. Another potential ally could be Shizune. She is Tsunade's assistant and she could see the potential in Naruto's power for the betterment of the village. Also, some of the younger female ninja trainees might look up to Naruto as a role model because of his power and become his allies, following his lead in different missions and battles.
Sakura could be a great ally. She is already a strong ninja and she respects Naruto's power. Hinata would also be likely. Her admiration for Naruto could turn into a strong alliance where she helps him in different ways, maybe using her Byakugan to assist him in battles. Tsunade too. As a powerful female figure, she could see the value in Naruto's unique power and side with him.
His friends like Sasuke and Sakura could be his allies. Sasuke might be initially skeptical but then see the potential of Naruto's arcane power in fighting common enemies. As for enemies, Orochimaru could be interested in Naruto's power for his own experiments. He might try to capture Naruto to study and steal his arcane abilities.
Sasuke could potentially be an ally. Given their complex relationship, Sasuke might understand Naruto's situation and choose to side with him. They have a deep bond, and Sasuke has also been an outcast in a way. Another could be Jiraiya. If he were still alive, he might believe in Naruto's innocence and help him from the shadows.
In some fanfictions, Naruto could form alliances with former enemies. For example, some members of the Akatsuki who have a change of heart might join forces with Naruto. This could be an interesting twist as they bring their unique skills and knowledge of the underworld to the fight. Additionally, some of the older generation of shinobi, who have retired but are forced to come back because of the severity of the war, could be his allies.
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.
Maybe some of the younger ninjas from other villages that he has inspired. For example, a young ninja from the Sand Village who saw Naruto's heroics during the Fourth Great Ninja War and now wants to join him in his quests. They could bring new skills and perspectives from their own village's ninja techniques.
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.
