Magic could be one way. In the RWBY universe, there could be some form of ancient magic that can change the nature of a Grimm. A character might discover a spell or a magical artifact that has the power to make a Grimm friendly. They would then have to figure out how to use it properly without any negative side effects.
Yes, there might be. The 'RWBY' fandom is quite large and diverse, so it's not surprising that there could be a fanfiction with such an interesting concept as Ruby being part Grimm. It could explore a whole new side of her character and the story's lore.
Well, in the context of RWBY fanfiction, the idea of Grimm breeding is quite a dark and controversial topic. Ethically, it goes against the natural order within the RWBY universe. Grimm are meant to be forces of destruction, and breeding them intentionally, even in fanfiction, can be seen as a perversion of the lore. It also raises questions about the motives of the characters involved in such a practice.
A magical artifact might be the source. For example, a long - forgotten amulet that was created by an ancient civilization with the power to influence Grimm behavior. If a character discovers this amulet and figures out how to use it, they can gain control over the Grimm. This could involve a complex process of deciphering the amulet's inscriptions and learning the proper incantations or rituals associated with it.
I think Jaune could be a likely candidate. He's a main character with a lot of development potential. His insecurities and his strong will to become a better Huntsman could be twisted if he were turned into a Grimm. It would create a great internal conflict as he battles his new nature.
Definitely Yang Xiao Long. Her fiery personality and her brawler - like fighting style can create some intense scenes when she crosses paths with the Grimm Reaper. Professor Ozpin is another one. His deep knowledge of the RWBY world and his mysterious past can add layers to a fanfiction involving the Grimm Reaper. Also, Cinder Fall. Her evil plans and her power - hungry nature can make for some great conflict when the Grimm Reaper is in the picture.
Writers often give them distinct physical features. For example, a humanoid Grimm might have multiple eyes or unusual skin textures. They also give them unique powers, like the ability to control shadows or manipulate ice in a way different from regular Grimm. Their backstories are important too. A humanoid Grimm could have been created from a rare experiment gone wrong.
In many Grimm fanfictions, Nick and Adalind's relationship is complex. Their initial interactions were often filled with mistrust as they were on different sides. But as the story progresses, they start to understand each other more. Their relationship could develop in various ways. For example, they might bond over their shared experiences in the Grimm world, like dealing with different Wesen threats. This could lead to a deep friendship that might eventually turn into a romantic relationship, with each learning to rely on the other in times of danger.
Another aspect could be the emotional journey. Nick might be initially worried about how to be a father, especially considering his dangerous life as a Grimm. Adalind, on the other hand, could be conflicted between her past actions and her new role as a mother - to - be. Their relationship could be put to the test as they navigate through these complex emotions.
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.
