How does Naruto and Kyuubi become friends in fanfiction?

Well, it often involves imagining unique powers and circumstances. Maybe a special ritual or a rare encounter could trigger the transformation.

The Fem Kyuubi might be in trouble or weakened somehow. Naruto senses this and instead of taking advantage, he offers his help. He uses his own chakra to soothe her or protect her from whatever is threatening her. This act of kindness surprises the Fem Kyuubi. She has never experienced such a selfless act from a human before. This makes her lower her guard and start to trust Naruto. They then start to interact more often, with Naruto bringing her stories from the outside world and the Fem Kyuubi sharing her ancient knowledge with him, thus forming a friendship.

In some fanfictions, Naruto and Kurama start to understand each other during their battles. As Naruto constantly shows his determination and never - gives - up attitude, Kurama begins to respect him. For example, when Naruto is facing a powerful enemy and still tries his best even on the verge of exhaustion, Kurama sees his tenacity and starts to have a change of heart. This is a common way for them to start building a friendship in fanfiction.

In some fanfictions, Naruto becomes friends with Kurama through deep conversations. Naruto, being persistent, tries to understand Kurama's pain and anger. He shares his own experiences of being alone and ostracized. This mutual sharing of feelings gradually breaks down the barriers between them, leading to friendship.

A common scenario is when Naruto is on the verge of death. The Kyuubi realizes that if Naruto dies, it might also be in a bad situation. So, it decides to cooperate and in the process, they start to understand each other better and become friends. Another is when Naruto enters the Kyuubi's lair in his mindscape and instead of fighting, he tries to have a peaceful conversation, which leads to friendship.

Well, their friendship develops through Naruto's determination. He doesn't see the Kyuubi as just a source of power. Instead, he tries to understand it. Naruto's positive attitude gradually breaks down the Kyuubi's initial hostility. As time goes by, they start to communicate more, and Naruto shows the Kyuubi that he respects it as an individual. This mutual understanding forms the basis of their friendship.

His friends might be a bit more cautious around him at first. After all, the Kyuubi is a very powerful and somewhat feared entity. But as they see that Naruto is still himself, they gradually become more accepting. For example, Sasuke might initially be on guard but then realize Naruto is still his friend.

If Naruto and the Kyuubi switch places, his friends might be initially very confused. They are used to Naruto's normal behavior. If the Kyuubi is in Naruto's body, it might be more aggressive or act in ways that seem out of character. His friends would have to figure out what's going on. But if Naruto is in the Kyuubi's place, his friends might start to worry about him more, not knowing what he's experiencing inside the seal.

When the Kyuubi possesses Naruto, his friends' trust in him is tested. Some, like Shikamaru, might be more cautious and try to keep an eye on Naruto to make sure he doesn't go out of control. Others, like Choji, might be more sympathetic and try to offer Naruto support. This possession changes the dynamics. Naruto might feel isolated as his friends struggle to understand what's going on with him, and it takes time for them to rebuild their normal relationships.

At first, Naruto might see the Kyuubi as just a source of power. But as he starts to protect it, he realizes it's more of a partner. Their relationship evolves from a simple user - power source dynamic to a deep - seated friendship. He begins to understand the Kyuubi's emotions and past, which further cements their bond.
