In some fanfictions, Kyuubi's protection is shown as a very direct physical act. For example, it might take over Naruto's body completely to fight off a powerful enemy. In others, it could be more of a mental or emotional support, like giving Naruto advice or calming him down during a difficult situation.
In a large number of Naruto fanfictions, Kyuubi's protection of Naruto is depicted in unique ways. There are those where Kyuubi's protection is a matter of survival for Naruto. For example, in a post - apocalyptic Naruto fanfiction where the world has been overrun by powerful and evil forces, Kyuubi might be the only thing that can protect Naruto from being killed or enslaved. Then there are fanfictions that play with the idea of Kyuubi's protection in a more humorous way. Maybe Kyuubi is constantly bickering with Naruto while still protecting him, like an over - protective but grumpy roommate. And in some more serious and character - driven fanfictions, Kyuubi's protection is part of Naruto's journey to self - discovery. As Naruto faces his inner demons and tries to figure out his place in the world, Kyuubi is there to protect him from the worst of his self - doubts and fears.
