Well, perhaps in this fanfic, Naruto being raised by Mikoto means he has a more stable and loving upbringing. He could be friends with Sasuke from a very young age, and they might grow up like brothers. Naruto would also be exposed to the Uchiha's rich history and culture, which could shape his understanding of the ninja world and his own place in it. He might even get to know some secrets of the Uchiha clan that no one else outside the clan knows.
One possible plot could be that Mikoto somehow survived and she takes Naruto under her wing. She trains him secretly, using her Uchiha knowledge to make him stronger. This could lead to Naruto having a unique set of skills that no one else has.
The plot could revolve around a mystery in the village that only Kushina, Mikoto and Naruto can solve. Maybe there are strange disappearances that are related to an ancient power that was once sealed by the Uzumaki clan and has some connection to the Uchiha. Kushina uses her knowledge of the Uzumaki history, Mikoto her understanding of the Uchiha lore, and Naruto his unique perspective as the Jinchuriki of the Nine - Tails. They have to overcome their differences and work together to save the village from this hidden threat. Along the way, they develop a deeper bond as they face various challenges.
A possible plot is that Mikoto stumbles upon baby Naruto in the forest. She takes him back to the Uchiha compound. There, she raises him as one of their own, much to the confusion of some Uchiha members. As Naruto grows, he starts to show unique abilities that are a combination of his Uzumaki heritage and the influence of the Uchiha environment.
Well, it could be about Mikoto seeing Naruto's lonely situation and deciding to take him in. Maybe she'd teach him some Uchiha techniques and help him grow stronger. She could also introduce him to Sasuke as a brother figure, changing the whole dynamic between Naruto and Sasuke in the Naruto world.
I'm not sure there should be such a fanfic as it involves some rather inappropriate and non - canon scenarios. Naruto has his own mother, Kushina, and Mikoto is Sasuke's mother in the Naruto universe. This kind of plot goes against the original setup of the story.
Well, the plot could involve Naruto being trained in a very different way. Since he's the son of Minato and Mikoto, he might be taught a blend of the Namikaze and Uchiha techniques. For example, he could learn to combine Minato's Flying Thunder God Technique with some basic Uchiha fire - style jutsu. And there could be a story arc about how he unites the two clans that his parents come from, which have had some historical tensions. He would have to use his unique heritage to bring peace between them.
Well, in this fanfic, Obito might raise Naruto to be more cynical about the Hidden Leaf Village. Since Obito has his own grudges against the village, he could influence Naruto's perception of it. However, Naruto's own kind heart might still shine through and he could end up trying to change Obito's views while still learning from him. For example, Naruto could use the power and skills he learns from Obito to protect the village in a new way, bridging the gap between Obito's distrust and the village's need for protection.
Well, one possible plot could be that Naruto grows up learning the Raikage's style of combat. He might become more physically powerful and aggressive compared to his canon self. Maybe he'd also form strong bonds with the Cloud ninja early on.
One possible plot twist could be that Mikoto discovers Naruto has a hidden kekkei genkai that she helps him unlock. This new power could completely change Naruto's abilities and how he's perceived in the ninja world.
One possible plotline could be that Naruto grows up with a different set of values. Mikoto might teach him more about the Uchiha clan's ways, which could influence his fighting style. He may also have a closer relationship with Sasuke from the start as they are both in the same 'family' of sorts.
