In the RWBY universe, colors are very important. Ruby is associated with red. Cinder calling her 'Red' might be a power play. It could imply that Cinder sees Ruby not as an individual with her own agency and skills, but simply as a representative of the color red, which in RWBY has certain connotations. Maybe Cinder is trying to undermine Ruby's identity within the context of the color - themed world they live in. It could also be a foreshadowing device in the fanfic, hinting at future conflicts or interactions between the two characters based on this simplistic view of Ruby.
In RWBY fanfics, when Cinder calls Ruby 'Red', it could be a simple way to refer to Ruby's signature red color in her outfit. It might also be used to show Cinder's somewhat dismissive or taunting attitude towards Ruby, reducing her to just a color rather than a fully - fledged threat. Additionally, it can be a quick way for the writer to add a bit of that RWBY - style banter into the fanfic.
In fan - created RWBY stories, when Cinder calls Ruby 'Red', it usually adds a layer of hostility. It makes their relationship more adversarial as it comes across as a belittling term from Cinder. Ruby would likely see it as a sign of disrespect, which would fuel her determination to oppose Cinder even more.
Redemption is also a popular theme. Since Cinder is a villain, many fanfics like to see if she can be redeemed, often with Ruby playing a key role in that process. For example, Ruby's kind nature might inspire Cinder to change.
There are so many RWBY fanfics out there that it can be a bit of a hunt to find one with this specific detail. You could also check out RWBY fan communities on Reddit or Tumblr. Sometimes fans will recommend great fanfics in those groups. Maybe post a request asking for a fanfic where Cinder calls Ruby 'Red'. That way, other fans who know of such a fic can point you in the right direction.
If in fanfiction Cinder is Ruby, it would be a total game - changer. Ruby is the symbol of hope in RWBY, and Cinder is a symbol of destruction. So, this switch would create a really interesting narrative. The story could explore how Cinder, in Ruby's body or identity, would deal with Ruby's responsibilities. Would she try to uphold Ruby's values? Or would she slowly corrupt them? And how would the other characters react? They might initially trust her because she looks like Ruby, but as they start to notice the differences in her behavior, it would lead to a lot of conflict and drama.
Yes, there might be. The RWBY fandom is quite large and creative, so it's possible that someone has written a fanfic with such a plot. You can check fanfic websites like Archive of Our Own or Fanfiction.net to see if there are any stories like that.
One common theme is redemption. Cinder is often portrayed as a character who might find redemption through her interactions with Ruby. Another theme is the power of understanding, as they come from very different sides in the RWBY world.
A RWBY fanfic with Ruby brainwashed by Cinder could be a dark and complex tale. The fanfic could start with the event of the brainwashing, perhaps Cinder using some sort of dark magic or psychological manipulation. Once brainwashed, Ruby's appearance might even change slightly to reflect her new state, like a darker look in her eyes or a more menacing stance. Her relationship with her team would be shattered. Yang, for example, would be extremely distraught and determined to get her sister back. The story could also involve other characters like Ozpin or Qrow trying to find a way to reverse the brainwashing. There would be a constant battle between Cinder's control over Ruby and Ruby's true self trying to break free, all while the fate of Remnant hangs in the balance as Cinder uses Ruby as a tool for her own malevolent purposes.
One great RWBY Ruby and Cinder fanfiction is 'The Unlikely Alliance'. It explores a scenario where Ruby and Cinder are forced to work together against a common enemy. The story does a great job of developing their characters in this new context.
One interesting concept could be the exploration of their opposing natures. Ruby is often seen as pure - hearted and full of hope, while Cinder is more devious and power - hungry. In fanfiction, this contrast can lead to some intense character - driven stories where they either learn from each other or clash in more complex ways than in the original series.
