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.
Perhaps a fanfiction where a long - lost ancient magic resurfaces in a character, enabling them to control Grimm. The character then has to struggle with the moral implications of using this power, as controlling Grimm is generally seen as a very dark and dangerous ability in the RWBY universe. They might try to use it for good, like stopping Grimm attacks without harming the Grimm, but face opposition from others who don't believe it's possible to use such a power benevolently.
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.
First, think about the origin of the Demonic Grimm. If it was created from some dark, ancient magic, it might have an otherworldly and terrifying look. For example, it could have a smoky, ethereal body with a skull - like face that constantly changes expressions to show its malevolence. Its attacks should be unique and deadly. Maybe it can drain the life force of its enemies just by touching them. And don't forget about its behavior. A Demonic Grimm that stalks its victims silently, always lurking in the shadows before pouncing, would be very scary.
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.
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.
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.
It could be an original character. For example, a young girl who discovers she is half - Grimm after an accident. She has to hide her true nature from others while trying to understand her powers.
First, give them a backstory that ties into the RWBY universe. For example, they could be from a family that has a history with Grimm research. Second, give them flaws. Don't make them all - powerful. Maybe they are afraid of the dark because of a bad encounter with Grimm at night. Third, have them develop relationships with the existing characters. If they are constantly butting heads with Yang because they are too reckless, it makes them more believable.
Well, popularity can vary. In the RWBY fanfiction world, there are so many different themes and concepts. While the idea of Ruby being a Grimm in a fanfiction is quite different and could potentially be interesting. However, it might not be as mainstream as some other common fanfiction themes like Ruby's relationships with her team members. So, it may not be extremely popular, but it could have a dedicated following among those who like more edgy or unique storylines.
