One popular Naruto fanfiction with a talking stuffed animal is 'The Stuffed Guardian'. It's really interesting as the stuffed animal has a secret past and special powers that it gradually reveals to Naruto, helping him in his ninja training and adventures.
One example could be a fanfiction where Naruto discovers a talking stuffed fox. This stuffed fox might have some hidden powers or knowledge related to the ninja world. It could start guiding Naruto in his training or even give him insights into his family's past.
The talking stuffed animal could also be a plot device. Maybe it holds a key to a mystery. For example, it could have a map hidden inside it that leads to a powerful weapon or a secret location that is crucial for the safety of the Hidden Leaf Village.
It could be a creation of some powerful ninja magic. Maybe a ninja with unique abilities created it as a tool or a companion, and it somehow ended up with Naruto.
They usually introduce new animal species or expand on the existing ones in the Naruto world. Like there could be some rare, powerful animals that only Naruto can befriend. These animals might have unique abilities such as the power to heal or to create illusions on a large scale.
It might be about a new villain in a Naruto fanfic who has a penchant for 'breaking stuff'. This could be physical things like buildings, or it could be more abstract like breaking the bonds between characters or breaking the established rules of the Naruto universe. Without reading the actual fanfiction, it's hard to say exactly, but it's likely centered around some form of destruction within the Naruto - inspired setting.
One popular Naruto fanfiction with animals could be 'Naruto and the Summoning Menagerie'. It often features Naruto forming unique bonds with various summoned animals in ways not shown in the original series.
Power exploration is also a big theme. Writers often take the opportunity to create unique and powerful abilities based on the animal bloodline. They might describe how a character can transform parts of their body into an animal form, like having fox ears and a tail for a character with a kitsune bloodline, and how they learn to control and use these abilities in combat or in daily life. And this exploration of power can lead to some really exciting action scenes in the fanfiction.
Obviously Naruto is one of the main characters. His nin animal would also be a main focus. There might also be his friends like Sasuke and Sakura who interact with Naruto and his nin animal in different ways. Maybe Sasuke is initially jealous of Naruto's unique nin animal.
One common theme is innovation. Naruto's inventions often bring new ways of doing things in the ninja world, like new combat techniques or tools. Another theme is problem - solving. His inventions are usually designed to solve a particular issue, such as a lack of communication between clans or a need for better defense against certain enemies.
