How do the characters in fanfiction react when Naruto loses control of Kyuubi?

In some fanfictions, when Naruto loses control of Kyuubi, other villages might see it as an opportunity to attack Konoha. They may think that with Naruto out of control, Konoha is in a weakened state. This could start a whole new arc of conflict where Konoha has to defend itself not only from Naruto's unleashed power but also from external threats.

Dumbledore would probably be very calm and have a long - term plan. He might use this as an opportunity to teach Harry something new or guide him in a different direction. Some of the teachers at Hogwarts might be worried about how this will affect Harry's performance in class and his safety at school.

The villagers' reaction would be mixed. Some would be in awe of Fem Kyuubi's power and her act of saving Naruto. They would see her as a hero and start to change their views on the Kyuubi in general. However, there would also be those who are still fearful. They might think that Fem Kyuubi has some ulterior motives and be suspicious of her. Naruto's friends from his ninja team, like Shikamaru and Choji, would probably be more accepting. They would welcome Fem Kyuubi as long as she proves to be on Naruto's side and doesn't cause any trouble for the village.

Naruto might initially be shocked and angry. He has always considered the Kyuubi as an enemy within him, and now being kidnapped by it is the worst - case scenario for him. He could try to fight back immediately, using whatever little chakra he can muster without relying on the Kyuubi's power.

When Naruto has full control of the Kyuubi in the fanfiction, it changes his relationships in multiple ways. His relationship with Kakashi becomes more of an equal partnership. Kakashi no longer has to worry about Naruto losing control. With Hinata, she may feel even more admiration for him as he has tamed such a powerful force. For the other ninja clans in the village, they may start to approach Naruto to learn from his control over the Kyuubi. This new - found status also gives Naruto more influence in the village's politics and decision - making, as his power is now seen as an asset rather than a liability.

Yuki would definitely be affected. She has a close relationship with Zero, and his loss of control could put her in danger. Also, she would be emotionally distraught seeing Zero in such a state.

Other characters in the Naruto universe might also be affected. For example, his friends like Sakura and Kakashi would notice the change in Naruto. They might try to help him, but their attempts could be in vain because of the complex situation with the Fem Kyuubi involved. This would create new tensions and storylines as they struggle to deal with a Naruto who has lost his sanity and the mystery of the Fem Kyuubi's role in it.

Some of his friends might be scared. After all, the Kyuubi is a powerful and dangerous entity. But then they would remember that Naruto is their friend. For instance, Ino might be a bit hesitant at first, but then she would use her skills to try and help Naruto deal with any negative emotions related to the Kyuubi.

He might gain it through a series of trials. Maybe he has to face his deepest fears in some kind of mental realm where the Kyuubi resides.

His combat abilities are enhanced greatly. With full control of the Kyuubi, Naruto can access its chakra more freely. This means he can enter the Nine - Tails Chakra Mode without the risk of losing control. His physical strength, speed, and endurance are boosted to superhuman levels. For example, he can move at incredible speeds, dodge attacks more easily, and deliver more powerful punches and kicks.
