I also like 'Ruby and Cinder: A New Beginning'. Here, they meet in a post - war world and decide to build a new society together. It's fascinating to see how they combine Ruby's ideas of equality and justice with Cinder's understanding of power structures to create something new.
There's also 'Cinder's Redemption Arc with Ruby'. In this fanfiction, Ruby plays a key role in Cinder's journey towards redemption. It delves deep into Cinder's past traumas and how Ruby's kindness makes her question her own actions and motives. This one is really interesting as it gives a lot of depth to Cinder's character.
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.
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.
Another option is FanFiction.net. Although the quality can vary, it has a vast number of RWBY fanfictions. You can use the search function and type in 'Cinder x Ruby' to see what comes up.
One great RWBY Cinder and Ruby fanfic is 'The Unlikely Alliance'. It explores a scenario where Cinder and Ruby are forced to work together against a common enemy. The story delves deep into their contrasting personalities and how they gradually come to understand each other.
One interesting fanfiction could be where Ruby and Cinder are forced to team up in an alternate universe. Maybe they have to fight a common enemy that's even more powerful than Salem. This would completely change their dynamic as they have to put aside their differences.
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.
The exploration of their backstories together is also a theme. Writers may create scenarios where Ruby and Cinder's pasts are somehow intertwined, perhaps revealing secrets that change their relationship in the RWBY universe.
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.
One good 'rwby ruby x cinder fanfiction' story could be 'The Unlikely Bond'. It explores how Ruby and Cinder, who are on opposite sides in the original series, might find common ground. Another is 'Red and Ash', which delves into a more complex relationship between them, where their powers interact in unexpected ways. There's also 'Ruby's Redemption of Cinder', where Ruby tries to turn Cinder from her evil ways.
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.
