Well, it could involve Ruby being influenced by an evil force in this fanfic. Maybe she's taught dark magic or has her moral compass twisted. For example, she might start seeing the world in a more cynical way and use her powers for less noble purposes.
Perhaps it could be an evil version of one of Ruby's own relatives. Like an alternate version of her father or mother who has been corrupted by some dark force. They would then raise Ruby with their evil values, making her believe that what they do is right and leading her down a dark path.
I'm not sure specifically as there could be many different takes in such a fanfiction. It might involve Ruby growing up under Cinder's influence, which could lead to a complete change in her character, values, and fighting style. Maybe Cinder has some ulterior motives for raising Ruby, like using her as a weapon or a pawn in her grand scheme against Beacon Academy and the other Huntsmen and Huntresses.
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.
It could be about Ruby being raised by Weiss instead of her usual upbringing in the RWBY world. Maybe it explores how Weiss's family environment and values shape Ruby's growth and development.
Maybe it's a mysterious figure from Ruby's family's past. Someone who had a connection to her mother or father and felt a sense of duty to raise Ruby. This would add a layer of mystery and family drama to the fanfiction.
It's difficult to say which 'rwby ruby raised by cinder fanfiction' stories are popular without doing some in - depth research. However, some factors that might make a story popular in this genre could be unique interpretations of Ruby's character development under Cinder's care, interesting plot twists, and good writing quality. You could try searching for such stories on platforms where RWBY fanfiction is commonly shared and then look at the number of views, favorites, and comments to gauge popularity.
Well, in such fanfictions, a prevalent theme could be transformation. Ruby's upbringing by Grimm would transform her in many ways, not just in terms of her skills and abilities but also her moral compass. Another theme might be discovery. As she starts to learn more about the world outside of the Grimm's influence, she discovers new things about herself and the true nature of the Grimm. There could also be a theme of acceptance, as she tries to find a place where she can be accepted for who she is, whether it's among the Grimm - haters or among the Grimm themselves, if there is such a possibility in the fanfiction world.
She might be more guarded. Qrow is a cautious person, and if he raised Ruby, she would likely pick up on some of his wariness. So instead of being as open and naive as in the original series, she could be more hesitant to trust new people right away.
Well, one possibility is that Ruby could be influenced by a powerful and evil relic. Maybe she discovers a dark side of the relic's power and becomes corrupted by it, gradually turning evil as she starts to value power over her friends and the greater good.
