The toads from Mount Myoboku could also be considered his allies in a new way. They could provide him with more powerful sage mode training or give him prophecies about future threats to the ninja world that he needs to face.
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.
In a crossover scenario, Naruto could find allies in characters from other anime. For instance, if he enters the world of One Piece, Luffy and his crew could be his allies. They share the common trait of having big dreams and a strong sense of loyalty. Luffy would be drawn to Naruto's determination, and together they could face any challenges in this new world.
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.
Maybe some of the Akatsuki members could be his secret allies. For example, Itachi might have had a secret plan and saw Naruto's potential, so he was secretly helping Naruto become stronger all along. Also, there could be some minor characters from other villages who have recognized Naruto's hidden power and decided to ally with him.
One potential ally could be Hinata. Hinata has a very gentle and empathetic nature. She could help Naruto by using her Byakugan to be his 'eyes' and describe the world around him. For example, in battle, she could tell him where the enemies are. Another could be Kakashi. Kakashi is a very experienced ninja. He could develop special training methods for Naruto that are more focused on his remaining senses. He could also use his Sharingan to sense threats and communicate that to Naruto in some way, like through a series of taps or vibrations.
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.
Rock Lee could be an ally. His determination and hard - working nature would be very useful in the rebuilding process. He could help with the physical labor of building structures. Also, some of the Uzumaki clan members who were scattered around different villages after Uzushiogakure was destroyed might come together and ally with Naruto to restore their ancestral home.
An alien race that is highly intelligent but physically weak. They see Naruto as a powerful protector. In return for Naruto's protection, they offer him their advanced technology which could be crucial in his journey back to his world. For example, they might give him a device that can create wormholes to different parts of the universe.
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.
One possible new ally could be a young duelist from a far - off land who has a unique dueling style. This person could bring new strategies and decks to the table, and they could team up with Jaden to take on common enemies. Another could be an old - time duelist who has retired but decides to come back to help Jaden when he realizes the threat that's facing the dueling world.
