At first, Naruto might be shocked and confused. He would probably wonder why his own clan would do such a thing to him. He might feel a deep sense of betrayal, especially since he has always longed for a family and a sense of belonging within the Uzumaki clan. But being Naruto, he would soon turn his confusion and pain into determination. He would vow to prove himself and show the clan that they were wrong to exile him.
Well, he could start a family with Hinata and have lots of kids, passing on his Uzumaki bloodline. Then, he could encourage his friends who have some Uzumaki connection, like Karin, to also have families and pass on their Uzumaki genes. He could also set up a school or training center in the Uzumaki land, teaching the Uzumaki ways of life and ninjutsu, which would attract orphans or those who want to be part of the Uzumaki clan.
There's also 'Naruto: The Uzumaki - Uchiha Alliance'. In this fanfic, Naruto forms an alliance between the Uzumaki and Uchiha remnants early on in his journey. It shows how this alliance changes the dynamics of the Naruto universe. There are some really interesting relationships that develop between the characters, and it's a great read for fans who want to see a different take on Naruto's story.
If Naruto saved the Uchiha clan, the story of the Hidden Leaf Village would be rewritten. The history of the Uchiha's massacre would no longer be a dark stain on the village's past. The Uchiha would contribute their unique skills and abilities to the village's development. For example, their Sharingan abilities could be used for better security or in battles against common enemies. There would also be a change in the relationships between characters. People who were once enemies of the Uchiha might have to learn to work with them.
In many fanfictions, Naruto's reaction is a mix of shock and determination. The shock comes from finally learning about his clan, and the determination is to uphold the Uzumaki name. He could start wearing something that represents the Uzumaki clan, like a symbol on his clothing. He also may become more protective of the Uzumaki secrets and legacies he discovers.
Naruto could also offer incentives for Uzumaki to have children. For example, providing better living conditions, education, and protection. He might also use his influence to find suitable partners for the remaining Uzumaki members, both within the village and from other allied villages. This way, they can start new Uzumaki families and gradually increase the clan's numbers.
Naruto Uzumaki and Uchiha Weasel were important characters in Naruto. Here are some stories related to these two characters:
Naruto: The Legend of the Nine Tails: It tells the story of the first encounter between Uzumaki Naruto and Uchiha Weasel, and also shows the relationship and conflict between them.
2 Naruto: The Legend of the Weasel God: This is a story about Uchi, the Weasel, and his growth, goals, and motives. In this book, Uzumaki Naruto also played an important role and had a conflict with Uchiha Weasel.
3 Naruto Naruto's Growth: This is a story about Naruto Uzumaki's growth, goals, and motives. In this book, Uchi also played an important role and had a conflict with Uzumaki Naruto.
4 Naruto: The Entanglement of Naruto: This is a story about Naruto Uzumaki and Sasuke Uchiha. It tells the story of their relationship and conflict. The role of Uchiha Weasel was also mentioned in this book.
One idea could be a time - travel fanfiction. Naruto Uchiha (assuming it's an AU where Naruto has Uchiha heritage) somehow travels back in time and meets Kushina Uzumaki. They could form an unexpected friendship as he tries to protect her from the events that would lead to her death. He could also use his knowledge of the future to change things in the village for the better.
Naruto could learn about the Uzumaki clan's sealing techniques. They were masters of sealing jutsu. In the fanfiction, he might find out how they developed these complex and powerful sealing techniques, which were passed down through generations. It could be that he discovers some unique seals that were only known to the Uzumaki clan and how they were used for various purposes, like containing powerful entities or storing chakra.
