Maybe Naruto is trying to find a way to bridge the gap between different races in his own world. So, he uses his knowledge of ninjutsu and some sort of ancient magic he discovers to create the Faunus. And then the story could be about how the Faunus adapt to their new existence and how Naruto helps them fit into the world.
I'm not sure of specific 'Naruto creates the Faunus' fanfictions off the top of my head. But you can try looking on popular fanfiction websites like Archive of Our Own or FanFiction.net. Search for the key phrase 'Naruto creates the Faunus' and browse through the results. Some might be really interesting with unique plotlines and character developments.
I'm not entirely sure as I haven't read this specific fanfiction. But it might be a story where Naruto is somehow placed in the world of Grimm Faunus, perhaps with Naruto having to adapt to the new environment, new powers related to being a Faunus, and facing the threats that come with the Grimm in that universe.
It could be really interesting. Naruto with the traits of a faunus would bring a whole new dynamic. Maybe he'd have some animal - like features that would enhance his ninja abilities. For example, if he was a fox - type faunus, it could tie in with the nine - tailed fox inside him in a unique way.
I'm not entirely sure specifically as there could be many different interpretations in such a fanfiction. It might involve Naruto in a world related to the Faunus concept, perhaps with Naruto having god - like powers within that context. Maybe he uses his skills to protect the Faunus or change their situation in some way.
Faunus in Naruto and RWBY fanfiction can be used to explore themes of discrimination. In RWBY, Faunus face discrimination, and this can be paralleled in the Naruto universe. Fanfiction might show Faunus being treated like the Jinchuriki or the Uchiha clan, who were also ostracized. They could be fighting for equality in the Hidden Leaf Village or other ninja villages, just like they do in RWBY's Vale or other kingdoms.
Well, in a 'naruto is a cat faunus fanfiction', it could center around Naruto's interactions within the cat faunus community. Since Naruto is usually known for his energetic and somewhat goofy nature in the original series, as a cat faunus, he might get into all sorts of misadventures. He could be trying to prove himself as a capable 'ninja' despite the differences in his new form. It might also involve his relationships with other characters from the Naruto universe, who now have to view him in a whole new light as a cat faunus.
One unique aspect is the combination of different power systems. Naruto has his chakra - based ninjutsu, like the Rasengan and Sharingan abilities in some crossovers. In RWBY, there are semblances and Dust - based powers. When these mix in fanfiction with the Faunus' natural abilities, it creates really cool and unique combat scenarios. For example, a Faunus with cat - like traits might use Naruto - style acrobatics along with their own natural agility and some new ninjutsu - inspired attacks.
Well, it combines two different and really cool concepts. Naruto has its own rich world of ninjas, jutsu, and complex characters. And the idea of faunus from another universe, in this case fox faunus, adds a whole new layer of diversity. It allows for unique character designs and abilities that you don't see in the original Naruto.
The unique elements are numerous. First, the faunus characteristics like animal - like features can be given to Naruto or other characters in new and creative ways. Second, the god aspect can change the power hierarchy. Naruto may no longer be just a powerful ninja but a being with god - given abilities that set him apart. Third, the fanfiction can explore new storylines such as Naruto having to save both the ninja world and the faunus world from a common threat that only his combined powers can defeat. It's this mixing of different concepts that makes 'naruto faunus god fanfiction' so special.
