Another idea is a time - travel fanfic. Cinder travels back in time and meets a younger Ruby. She could try to manipulate Ruby into following a different path, but Ruby's strong will and sense of justice might resist. This would create a lot of conflict and interesting character dynamics as Cinder tries to change the future and Ruby tries to protect it.
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.
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.
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.
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.
Well, one possible plotline could be Ruby and Cinder being forced to team up in an unexpected situation. Maybe they have to face a common enemy that is far more powerful than either of them alone.
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.
One common theme is the exploration of the relationship between good and evil. Ruby represents the good side, and Cinder is often seen as the antagonist. Their relationship in fanfictions might explore how they can influence each other's views on this dichotomy.
One interesting fanfiction could be about Cinder and Ruby having to team up temporarily to face a common enemy. In this story, Ruby's optimism might start to chip away at Cinder's cold exterior.
