Well, if Naruto were Sarada's father in fanfiction, it would completely change the family dynamics. For one, Sasuke's role would be very different. Sarada's character might develop different values and abilities, influenced by Naruto instead of Sasuke. The relationship between the Uchiha and Uzumaki clans would also take on a new form, perhaps leading to new alliances and political situations within the Hidden Leaf Village.
If Naruto was Sarada's father in fanfiction, it could mean a whole new set of adventures. Sarada might grow up with Naruto's positive and energetic attitude. Her training would likely be different, focusing more on Naruto - style techniques like the Rasengan. Also, the relationship between Boruto and Sarada would be more like siblings, which would change their interactions and how they face challenges together in the story.
In this fanfiction scenario where Naruto is Sarada's father, the story would be drastically altered. Naruto's influence on Sarada would be profound. His dream of being Hokage and his belief in friendship and hard work would be instilled in her from a young age. This could lead to Sarada having a different view of the world compared to her canon self. Her relationships with other characters, such as Sakura (who would no longer be her mother in this scenario), would be completely different. And it would also have an impact on the future of the Hidden Leaf, as Sarada's actions and decisions would be shaped by Naruto's parenting.
