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.
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.
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.
The Uzumaki clan bloodline can also be used in fanfics to explore family and heritage. Characters might discover long - lost secrets about their Uzumaki ancestry that change their view of themselves and their place in the ninja world. It could be something as simple as a new jutsu that was forgotten by the clan but is now accessible to the main character because of their Uzumaki blood, or it could be a much deeper connection to a prophecy or an ancient power.
Well, it could be that the Uzumaki clan has some hidden knowledge or ancient artifacts. In the fanfiction world, they might discover an artifact that has the power to save Naruto from a life - threatening situation. Maybe it's a charm that can heal his wounds or reverse a curse placed on him. And since the Uzumaki clan has a rich history, there are many ways they could use their heritage to save Naruto.
Yes, there are likely fanfictions with this premise. Naruto being an Uzumaki has a strong connection to the clan. In many fanfictions, authors explore the idea of Naruto taking on the role of the clan head. This can lead to various storylines, such as him restoring the Uzumaki clan to its former glory, uniting remaining members, and using his position to bring about positive change in the ninja world. It also allows for exploration of Uzumaki clan lore and powers that Naruto could inherit and develop further.
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 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.
They could change the storyline by providing Naruto with a stronger support system. Since they are his clan members, they might have knowledge and skills that can help him in his battles and his journey to become Hokage.
