There's also 'The Hidden Potential'. In this fanfiction, the OC's special abilities are explored in a way that ties in well with the RWBY universe. The lemon elements add an interesting aspect to the relationships. It really shows how an OC can fit into the RWBY world while having those more mature interactions.
As mentioned before, lemon fanfics often have adult - related themes which are not appropriate to discuss in detail. But generally, they might have themes of romantic or sexual relationships between original characters and existing RWBY characters.
Give him a distinct fighting style. Since he's op, it could be something that combines different martial arts and his special powers.

As for the lemon aspect, keep it in line with the overall tone of the story. If it's a more serious story, the lemon parts should also have some depth. Don't just write it for the sake of it. Also, use proper grammar and description to make the story vivid.
Next, focus on character development. Show how the OC and Raven interact and change over time. Their relationship could start with mistrust and gradually turn into respect or even friendship. Also, make sure to stay true to the RWBY universe. Use the existing lore, like the Grimm and the Huntsman academies, to add depth to your story.
When writing a RWBY OC x Ruby fanfic, it's important to stay true to the RWBY universe. Keep the lore and the world - building in mind. For instance, don't give your OC an ability that completely goes against the established rules of the world. Also, build up their relationship gradually. Have them go through challenges together, like fighting a tough Grimm or dealing with a difficult situation in Beacon Academy. This will make their bond more believable.
