If Naruto was part of the Uchiha clan in fanfiction, it would be really interesting. The Uchiha are known for their powerful Sharingan and their complex family dynamics. Naruto being part of it would mean he'd be involved in all of that. He might have a natural rivalry with other strong Uchiha members. His training would focus more on Uchiha - specific jutsu. Also, his relationship with Kakashi could be different, as Kakashi has his own connection to the Uchiha. The story could explore how Naruto uses his Uzumaki traits in combination with Uchiha abilities to create unique fighting styles and solve the problems in the ninja world.
Well, it would be a really dark turn. In the normal Naruto story, the Uchiha clan was massacred mainly by Itachi. If Naruto was the one doing it, it would mean he had a major shift in his values. Maybe some super - evil force could have influenced him. This would also lead to different power dynamics in the Hidden Leaf Village. People who trusted Naruto would feel betrayed, and those who were already wary of him would have a reason to go against him. It would be chaos.
One way Naruto could save the Uchiha clan in fanfiction is by using his influence. Naruto is highly respected in the village. He could convince the village elders to re - evaluate their treatment of the Uchiha. He might show them that the Uchiha were being wrongly persecuted and that there was a way to co - exist peacefully. He could also use his power as a Jinchuuriki to protect the Uchiha from any external threats that might be a factor in their downfall.
Well, in this fanfiction scenario where Naruto kills the Uchiha clan, it would mean the end of the Sharingan bloodline in a very unexpected way. This would have huge implications for the ninja world. Without the Uchiha, there would be no potential for the Mangekyou Sharingan or the Eternal Mangekyou Sharingan. The balance of power in the ninja world might shift as the Uchiha were quite powerful. And Naruto himself would be a very different character. He's always been about protecting and saving people, so this act would make him a much darker and more complex figure, almost an anti - hero.
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 this fanfiction scenario, Naruto killing the Uchiha clan would make him an outcast in Konoha. The village that once supported him would turn against him. This could lead to Naruto leaving the village and becoming a rogue ninja. He might then form his own group of allies who believe in his cause, whatever that might be in this altered story. It would also change how the Akatsuki views Konoha. Instead of targeting Sasuke, they might target Naruto directly as the one who eliminated the powerful Uchiha clan.
Well, one possibility is that Naruto would be trained in the unique Uchiha techniques. He might learn how to use the Sharingan in ways that no one expected. Also, he could gain a new family within the Uchiha clan, which would change his whole perspective on life and belonging.
Madara's grandfather could have had an impact on the clan's relationships with other ninja groups. If he was respected by other clans, it would have improved the Uchiha's standing in the ninja world. On the other hand, if he made enemies, it could have led to long - term rivalries and conflicts that Madara would have to deal with later. His actions and decisions in this regard would have shaped the Uchiha clan's place in the overall ninja society.
Well, if Naruto were to massacre the Uchiha clan in a fanfiction, it might be because of a huge misunderstanding. For example, false information could have been spread that the Uchiha were planning something really bad against the village. Naruto, in his haste to protect the village, could have been tricked into believing it and taking drastic action. However, this is a very dark and out - of - character concept for Naruto.
He would definitely have the Sharingan. With the Sharingan, he could copy jutsu more easily and have enhanced perception in battle. Also, he might inherit some of the Uchiha's fire - style jutsu, which would add to his combat abilities.
It could be a situation where Naruto discovers some dark secret about the Uchiha clan that he believes makes them a danger to everyone. For instance, if he found out they were planning a coup that would involve mass destruction, he might think that killing them was the only way to save the village and the rest of the ninja world.
