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.
Survival is also a big theme. When Naruto is thrown into the Grimm world, he has to use his skills to stay alive. This theme of fighting against the odds in an unfamiliar and often hostile environment is quite prominent. For example, in many fanfictions, Naruto has to face Grimm monsters much stronger than him at first. He has to quickly adapt and find ways to defeat them. Another theme could be the discovery of self. As Naruto navigates this new world, he learns more about his own abilities and limitations, and how he can grow beyond them. This is especially true when he encounters new magic or powers in the Grimm world that he has to incorporate into his fighting style.
Well, Naruto and Grimm fanfiction are from different fictional universes. Naruto is a well - known ninja - based anime, while Grimm fanfiction is based on the Grimm series. Maybe in this specific 'naruto is a grimm fanfiction', the author might be trying to cross - over the two concepts, like having Naruto characters in a Grimm - like setting, or using Grimm's narrative styles to tell a Naruto - related story.
Well, it could be that Naruto somehow gets transported to the RWBY universe and has to deal with the Grimm. Maybe he uses his ninja skills to fight them off. For example, his shadow clone jutsu could be used to confuse the Grimm while he attacks from another angle.
If Naruto creates Grimm fanfiction, perhaps he would imagine himself as a Huntsman in the Grimm world. He might use his shadow clones to outnumber the Grimm. His ninja skills like the Rasengan could be transformed into some sort of super - attack against the Grimm. Also, he could bring the concept of chakra into the Grimm universe and have the characters use it to fight the dark creatures.
I'm not entirely sure what it specifically means. 'Naruto' is a well - known anime/manga and 'Grimm' is another different series. Maybe it's a very strange or unique fan - created story that somehow combines elements of Naruto and Grimm in a way that is claimed to be the first of its kind.
Some specialized Naruto or Grimm - related fanfiction communities might also have it. You can look for forums or groups dedicated to either Naruto or the Grimm Faunus concept. There, you can ask the members if they know where to find this particular fanfiction. Another option is to check out some of the more well - known Naruto fanfiction blogs. They sometimes feature unique crossovers like this one.
A possible fanfiction could focus on a team-up between RWBY and Naruto characters against a common enemy that has the power of both Grimm and some dark ninja jutsu. For example, they might have to face an evil organization that is using Grimm to create chaos in the Naruto world while also using forbidden ninja arts. Or perhaps a fanfic could explore the concept of a RWBY character having a Sharingan - like ability that they gain in the Naruto world and how it changes their combat style and relationships with others.
One interesting 'naruto grimm faunus fanfiction' could be about a character from Naruto ending up in the world of Grimm and Faunus. Maybe Naruto himself discovers the unique powers and races there and has to adapt to survive. He could form alliances with the Faunus and fight against the Grimm using his ninja skills.
In terms of plot, it could start with Naruto being transported to a Grimm - like world. Then he has to figure out how to survive using his ninja skills. Maybe he teams up with some Grimm - like characters who are actually good, and they fight against the evil forces together.
