Besides Kaguya and Naruto, Sasuke is a key character that would be involved. Their rivalry - turned - friendship makes it necessary for him to step in. Then there's Kurama, the Nine - Tailed Fox inside Naruto. Kurama might be able to resist Kaguya's control to some extent and try to communicate with Naruto's consciousness. Also, characters like Shikamaru, known for his intelligence, could be involved in devising plans to break Kaguya's control over Naruto. Other shinobi from different villages might also get involved if they realize the danger that Naruto under Kaguya's control poses to the entire ninja world.
Sasuke would most likely be involved. Since he has a strong bond with Naruto, he would sense something is wrong and try to free Naruto from Kaguya's control. Sakura might also be part of it as she cares about Naruto and would be determined to save him. Kakashi could play a role too, using his wisdom and experience to figure out a way to break Kaguya's hold on Naruto.
Kakashi can be a popular character too. His wisdom and combat skills can be useful in fanfic scenarios involving Kaguya. He could be a mentor figure to Naruto, guiding him in dealing with Kaguya - related threats or helping to decipher ancient ninja knowledge related to Kaguya.
The two main characters would be Naruto and Kaguya for sure. However, depending on the plot, other important characters from the Naruto universe could make an appearance. It could be the tailed beasts, as Naruto has a strong connection with them. If the situation involves something related to the chakra of the ninja world, the tailed beasts might be involved in some way. Or perhaps characters from the Otsutsuki clan could be relevant if Kaguya's actions are related to her clan's history or powers.
One possible plotline could be Kaguya using her powers to manipulate Naruto into fighting his friends. She might twist his perception of right and wrong, creating chaos in the ninja world. Another could be Kaguya trying to use Naruto as a vessel to regain her full power and reshape the world according to her will.
Sasuke can also be involved in some cases. Since he and Naruto are often together in many situations, Sasuke's presence might add some complexity to the relationship between Kaguya and Naruto. For example, Sasuke might be suspicious of Kaguya's intentions towards Naruto at first.
Sasuke could be a likely candidate. He has always been Naruto's rival, and if he sees Naruto teaming up with Kaguya, who was once a great threat, he might oppose them. He may suspect that Kaguya has some ulterior motive and that Naruto is being naive in trusting her.
Obviously Naruto would be one of the main characters since it's about him being the heir of Kaguya. Sasuke could also be a main character as Naruto's rival and friend. Sakura might be involved too, as she is part of Naruto's team. And there could be other characters like Kakashi, who would play a role in guiding Naruto as he discovers his new identity. There might also be some new characters introduced that are related to Kaguya's past, who either help or hinder Naruto on his journey.
Well, Naruto could change Kaguya in the fanfiction by introducing her to the concept of redemption. Given his own journey of facing his inner demons and coming out stronger, he might convince Kaguya that she can atone for her past sins. He may take her on a journey through the ninja world, showing her how people have rebuilt and thrived despite the chaos she once caused. This could make her re - evaluate her actions and change her perspective on the world and her place in it.
Yes, there are likely some fanfictions that explore a special connection between Naruto and Kaguya. In some fanfictions, authors might create scenarios where Naruto, due to his unique abilities and kind - hearted nature, manages to reach out to Kaguya in a way others couldn't. This could involve him understanding her past and trying to bring some form of redemption or peace to her.
Sasuke could be involved. Since they have a complex relationship, Sasuke might either be a rival during Naruto's training, pushing him to be better, or he could end up joining Naruto in some training sessions to become stronger together.
Sasuke is likely to be involved. He and Naruto have a complex relationship and Sasuke has become an ally. He could offer his strength in combat to protect the rebuilding efforts. Also, Sakura. She's a skilled ninja with medical abilities that could be useful if there are any injuries during the process.
