In a Naruto fanfic where Mikoto is brainwashed, she could be made to do things against her normal nature. For example, she might be forced to fight against her friends or family. Maybe she'll be used as a tool by the villains in the fanfic's plot to gain some advantage over the other characters. It really depends on the creativity of the fanfic writer.
If Mikoto is brainwashed in a Naruto fanfic, it would be a really interesting plot twist. First, it would change the power dynamics in the story. Since Mikoto was a powerful Uchiha, her being under someone else's control could shift the balance. Second, it could be used to explore themes of mind control and free will. The author could show how Mikoto struggles against the brainwashing, or how the other characters react to her new state. It could also create some really emotional scenes, like when her loved ones try to reach out to the 'real' Mikoto inside.
Well, Naruto would likely gain a different perspective on the Uchiha. Mikoto could share stories about Itachi and Sasuke when they were younger. This would make Naruto understand Sasuke on a deeper level. For example, he might realize why Sasuke is so driven by revenge and be better equipped to handle their relationship.
Brainwashed Mikoto can have a huge impact on the plot. She could be used to start conflicts. For example, if she attacks other characters without reason due to the brainwashing, it would lead to battles and new rivalries.
Well, they could become rivals. Since Naruto is always striving to be the best and Mikoto, being from the Uchiha clan, would also be highly competitive. They might compete in various ninja tasks and exams, constantly pushing each other to improve.
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.
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.
In this fanfiction, perhaps Mikoto could teach Naruto some unique Uchiha techniques. Since she's from the Uchiha clan, she might have insights into fire - style jutsu that could help Naruto diversify his skills.
Well, one way could be that Naruto accidentally stumbles upon Itachi's plot against Mikoto. Maybe Naruto was in the right place at the right time, and using his ninja skills and his never - give - up attitude, he manages to fend off Itachi and save Mikoto. Naruto is known for his quick thinking in dangerous situations.
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.
One possible storyline could be that Naruto learns unique skills from Mikoto. Maybe she teaches him some of the Uchiha clan's secret techniques, like fire - based jutsu, which would be really interesting as Naruto is mainly associated with wind - style. This could also lead to Naruto having a closer connection to the Uchiha, which would change his relationships within the village.
