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.
One possible plot could be Ruby initially trying to hide her Grimm part from her friends. As she struggles with newfound abilities and instincts, she has to constantly fight the urge to give in to the Grimm side. Meanwhile, a powerful enemy emerges that she might be uniquely suited to defeat because of her Grimm part, but she has to first come to terms with it herself.
It could be a powerful Grimm - like being that has evolved beyond the normal Grimm. This antagonist might have the ability to think and strategize like a human, making it a much more dangerous foe for Ruby and her team. It could be leading the Grimm attacks in a more organized way, targeting specific areas to cause maximum chaos.
One idea could be Ruby facing a new type of Grimm that has unique abilities, like the ability to manipulate time in a small area. This would put Ruby in a tough situation where she has to figure out how to combat it while being affected by the time distortion. Another plot could involve Ruby getting lost in a Grimm - infested area and having to rely on her wits and the little resources she has to survive and find her way back to her team.
I'm not entirely sure if there is a specific 'RWBY Ruby is a Grimm Faunus' fanfiction. However, given the creativity of RWBY fans, it wouldn't be a surprise. Some fanfictions explore really out - of - the - box ideas, and this could be one of them. You could also check RWBY - related forums where fans might discuss or share such unique fanfictions.
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.
Well, Ruby might first be very cautious. She could use her Crescent Rose to keep a safe distance while observing the baby Grimm's behavior. Maybe she tries to figure out if it has any special needs like food (although it's a Grimm, which is strange to think about food for them).
I'm not entirely sure as it could vary greatly depending on the author's creativity. It might explore how Ruby's character would develop if she was raised by Grimm. Maybe she would have a very different set of skills or a darker personality.
In some RWBY fanfictions, the idea of Ruby being half Beowulf Grimm can be a creative and out - of - the - box concept. However, in the official RWBY canon, there is no such indication. Fanfiction writers often like to explore unique and alternative storylines that deviate from the original lore, and this is one such example.
I'm not entirely sure if there is a specific 'Ruby is part Grimm x Weiss' fanfiction. The 'RWBY' series has inspired a plethora of fan works, but this particular concept seems rather niche. It would depend on the creativity and interests of the individual fanfiction writers. Some might find the idea of Ruby having Grimm aspects and being paired with Weiss an interesting premise for a story, while others might not. You could also try reaching out to 'RWBY' fanfiction enthusiasts on social media platforms to see if they know of any such works.
