Well, if this is a real fanfic, it's a bad example of the fanfic world. The world of fanfiction should be a place for creativity within the bounds of respect and legality. A plot like this not only disrespects the characters but also can be very triggering for those who may come across it.
The exploration of their backstories in relation to each other is also important. For example, how their past experiences, like Ruby's upbringing in a loving family compared to Cinder's more troubled past, influence their present interactions. Fanfic writers often use this to build a deeper connection between the two characters, making the story more than just a simple relationship story but also a study of how their pasts shape their present and future together.
In 'cinder captures ruby fanfic', the notable works might be those that add a new dimension to the characters. Some fanfics could be centered around Cinder's motives for capturing Ruby. Is it for power, revenge, or something else? And then, there are those that might play with the idea of Ruby's resistance and how she outsmarts Cinder's attempts. Additionally, the ones that have detailed descriptions of the settings and interactions between the characters would also be considered great works in this genre.
Good character development makes a Ruby x Cinder fanfic great. If the author can show how their relationship evolves over time, it's a plus. For example, Ruby starting to see Cinder's more complex side.
A common theme is friendship. Since they are from different backgrounds, their journey to become friends is often explored. Another is redemption. Cinder might be a character with a troubled past, and Ruby can be the catalyst for her change.
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.
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.
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.
Perhaps the fanfiction could be about Cinder Fall being sent back in time to a point before she became evil and meeting Ruby as a child. Ruby's kindness towards Cinder at this early stage has a profound impact on her. As Cinder grows up, she constantly struggles between her original dark destiny and the new path that Ruby's friendship has opened up for her. This internal conflict could be the central theme of the story.
