Kakashi could be an important ally as well. His calm and strategic mind would complement Naruto's more impulsive nature. Kakashi could assist Naruto in analyzing the time - related threats and coming up with effective plans to counter them.
Maybe Kurama, the nine - tailed fox inside Naruto, could be an unexpected ally in a new way. Since they have a bond, Kurama could provide Naruto with extra power and insights when dealing with time - related challenges. For example, Kurama might have some ancient knowledge about the flow of time that could help Naruto in his time - patrolling duties.
In this fanfiction, Naruto might use his ninja skills while time patrolling. He could be tasked with preventing villains from changing important events in the Naruto universe's history. For example, stopping someone from killing a key Hokage in the past.
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.
One possible interesting plot could be Naruto being sent back in time to the founding of the Hidden Villages. He could use his knowledge from the future to prevent some of the early conflicts and shape the ninja world in a more peaceful way from the start.
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.
