In the fanfic, Naruto could potentially have some hidden power or connection that he uses to his advantage. For example, he might discover a long - lost prophecy that says the Uchiha are crucial for the future of the village. He then uses this knowledge to persuade everyone that the Uchiha should be spared. He might also enlist the help of his friends and allies, like Sasuke, to show a united front against the idea of the massacre.
In some fanfictions, Naruto might use his unique jutsu like the Rasengan. He could use it to break through barriers or fight off Uchiha attackers, creating an opening for his escape.
Naruto could also use his new jutsu or skills he has acquired. He might show Sasuke that he has become stronger and that they could face whatever Sasuke is running from together. He could block Sasuke's path physically and then start talking some sense into him, like how leaving won't solve his problems but will only create more.
In many fanfics, Naruto might save the Uchiha clan by preventing the massacre. He could use his influence and friendship to change Itachi's mind. For example, if Naruto had known about the threat to the Uchiha clan earlier, he might have been able to talk to the village elders and find a peaceful solution. He could also have protected the Uchiha clan from outside threats that might have led to their downfall.
Well, it depends on the specific fanfic. There are countless fanfictions out there, and some might indeed have a plot where Naruto has a secret connection to the Uchiha clan. Maybe it's a result of some hidden family ties or a magical spell that makes him related to them in some way.
Well, the OC might try to prevent the Uchiha Massacre. Maybe they have a different view of the Uchiha compared to the Konoha leadership. They could try to convince the Uchiha to flee or negotiate with Konoha. If they have unique powers or knowledge, they could use it to expose the real motives behind the planned massacre and create a situation where the Uchiha are spared. This would completely rewrite the story of the Uchiha's downfall.
The Otsutsuki OC might be an unexpected bystander during the Uchiha Massacre. For example, they could have been on a different mission in Konoha when the massacre started. They might then decide to get involved, either to save some Uchihas out of a sense of justice or because they see potential in the Uchiha bloodline for their own purposes. So, they end up interfering with Itachi's plan and creating a whole new set of consequences for the story.
The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
Well, in many Naruto fanfics, the Uchiha are often associated with powerful and unique weapons. The sword might be a symbol of their clan's power and heritage. It could also potentially be a weapon that has been passed down through generations, holding special abilities or techniques that only the Uchiha can unlock or use effectively.
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.
It could be Sasuke's sister, if there was one in the fanfiction world. She might share some of Sasuke's traits but also have her own unique personality that attracts Naruto.
