One plotline could be that Naruto was mind - controlled by a powerful villain. He wakes up to find he has killed his clan and has to deal with the shock and guilt while also trying to clear his name.
Well, I'm sure there are. Fanfiction writers often come up with wild and creative ideas. In a 'naruto killed his clan' fanfiction, it could show how Naruto would be ostracized even more than in the original story, and how he would deal with the guilt and hatred from others. It might also explore if there are any forces that could redeem him in such a dark situation.
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.
In this fanfiction, Naruto could reject his clan because of the dark secrets or past actions of the clan. He is a character who values justice and friendship. If the clan has a history of wrongdoings that he discovers, he may not want to be associated with it. Also, Naruto has his own dreams and goals that might not fit within the framework of the clan. He has always been a bit of a rebel, and rejecting the clan could be his way of standing up for what he believes in.
One possible reason could be to seek greater power and training opportunities elsewhere. Maybe he feels restricted within his clan in terms of the type of jutsu he can learn or the level of training he can receive. So, he decides to leave to explore different ninja arts and grow stronger on his own terms.
Naruto might recruit individuals who have unique talents that can contribute to the clan. For example, someone with exceptional medical ninjutsu skills could be a valuable addition. He may also look for those who have a great deal of loyalty and perseverance, as these are qualities he values highly. In addition, he could recruit those who have been ostracized or overlooked in the village, giving them a new family and purpose within his clan.
He could start by gathering like - minded individuals. Maybe those who share his ideals of hard work and perseverance, like some of the underdogs he befriended throughout his life in the original Naruto story.
First of all, Naruto would have to establish the clan's home base. In the fanfiction, it could be a hidden village within the existing Hidden Leaf Village or a secluded area outside. He would also need to decide on the clan's hierarchy. Who would be the leaders, the elders, and the regular members? Additionally, he would need to pass on his knowledge and skills to the new clan members, perhaps by creating a special training regime.
One challenge is the lack of pure - blood Uzumaki. Since he is the last one he knows of, finding suitable mates with enough Uzumaki blood could be difficult. Also, the Uzumaki clan has a lot of enemies. Those enemies might try to stop Naruto from reviving the clan so they don't become a threat again.
Perhaps there were some dark secrets in his clan that he discovers. These secrets could be related to past wrongdoings, like how they treated other clans or individuals. If Naruto has a strong sense of justice, learning about these things might make him hate his clan. It could also be that he feels ostracized or different within his clan, like if he has abilities or beliefs that are not accepted by the majority of the clan members.
