The Hyuga clan could also be a possibility. Given their strong bloodline and their focus on family and tradition, they might adopt Naruto. They could teach him their Gentle Fist technique. And Naruto could use his unique energy and determination to perhaps improve or modify the technique in some way. Plus, he could help the Hyuga clan with any external threats they face due to their valuable Byakugan.
In my opinion, it could be Mr. Bumble from 'Oliver Twist'. He is a rather pathetic and weak character. He is self - serving, cowardly, and easily manipulated. He is constantly outwitted by those around him, especially by the wily characters in the underbelly of London society that Dickens portrays.
Fanfiction often takes creative liberties with Naruto clan kinjutsus. Writers may create new variations of existing kinjutsus or even invent entirely new ones. This can add an exciting element to the story, especially when these new kinjutsus are used in battles or to solve complex problems within the fan - created plot.
One challenge would be getting other shinobi to join. Some might be loyal to their existing clans. Also, there could be political opposition in Konoha. The elders might not be too keen on a new clan being formed.
Well, Naruto could start by gathering like - minded shinobi. He's got a lot of friends and allies. Maybe he'd find those who share his ideals about peace and unity. Then, he could start training them in his own unique ninja techniques, which could form the basis of the clan's fighting style.
Naruto would probably start at the bottom of the clan's hierarchy. He is an outsider after all, and the Aburame clan has its own traditions and ways of doing things. But with his determination and strong will, he'd quickly work his way up. His combat skills, even if not related to the Aburame's at first, would earn him some respect. For example, his ability to defeat powerful opponents with his rasengan would show the clan members that he has potential.
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.
Another possibility is the Aburame clan which has a relationship with insects. They can control bugs and use them in combat. In the context of the fanfic, if Naruto were part of this clan, it would completely change his fighting style and how he interacts with the world around him. He would have to rely on the insects' abilities instead of his own chakra - intensive attacks like the Rasengan.
Well, in some fanfictions, Naruto might start by finding suitable partners within the village. Since he is the last of his clan, he could look for women who are willing to carry on the Uzumaki bloodline. He may also use his influence as a hero to encourage others to support his clan - revival efforts, like getting the village to provide resources for the new Uzumaki generation.
