The plot could involve Cinder's pregnancy being a result of some sort of experiment or magical mishap. She then has to figure out how to either keep the baby or reverse the situation, all while still being a major player in the RWBY universe.

Since I haven't delved into this specific 'rwby enslaved by cinder fanfic', it's hard to say precisely. However, in fanfics like this, it could be that Cinder uses their weaknesses or secrets against them to enslave the RWBY members. It may also show the different reactions of each RWBY character - Ruby's determination to fight back, Weiss's pride being challenged, Blake's struggle with her past and how it relates to this new situation, and Yang's strength being put to the test in this enslaved 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.
One idea could be Cinder being transported to an alternate universe within the RWBY world where the roles are reversed. For example, she could find herself in a world where she is a huntress in training, facing the same challenges as the main characters but from a different perspective. Another plot could involve a team - up between Cinder and a group of RWBY characters against a common, greater enemy that threatens both their goals and the world. Maybe a new, powerful Grimm that has abilities they've never seen before.

A good RWBY Cinder fanfiction often has a deep exploration of her character. Since she's a complex and somewhat mysterious character in the original series, fanfictions that peel back the layers, like showing her past traumas or her true desires, tend to be great. For example, if it delves into why she's so power - hungry.
A common theme is power and ambition. Cinder is a very ambitious character in RWBY, and many fanfictions explore her drive for power further. For example, she might be on a quest to gain even more power than she already has in the show. Another theme is redemption. Some fanfics like to imagine if Cinder could be redeemed and what it would take for her to turn away from her evil ways.
There's also 'The Hidden Side of Cinder'. This one focuses on Cinder's relationships with other characters in a more in - depth way. It shows how she might interact with people outside of her usual villainous deeds and gives a fresh perspective on her character.
