A plot could revolve around Raven getting injured during a battle. Cyborg takes it upon himself to nurse her back to health. As he tends to her, they have long conversations that lead to a deeper understanding of each other. This newfound closeness could then develop into a romantic relationship in the context of the fanfiction.
Perhaps there's a plot where a spell goes wrong in the Titans' Tower and Raven and Cyborg's minds are linked. They start experiencing each other's emotions and memories. This forces them to confront their feelings for each other in a very unique and intense way. Through this experience, they might realize that they have a special connection that could be the basis for a romantic relationship.
Slade could be included as an antagonist. His evil plans could somehow be related to the relationship between Raven and Cyborg. Maybe he wants to use their newfound love against them, or he tries to break them apart to weaken the Titans as a whole.
One idea could be Raven struggling with her powers in a new way. Maybe there's a spell that backfires and gives her a strange new ability that she has to learn to control. This could lead to some comical situations as well as some self - discovery for her character.
One idea could be Ruby adjusting to her new cyborg body and the enhanced abilities it gives her, like super - strength or advanced weaponry integration. Another could be her facing discrimination from some in the RWBY world who fear or mistrust cyborgs.
Perhaps a fanfiction where Cyborg teams up with a character from a different universe. They could learn from each other's skills and technology, like if he teamed up with a character from a more magic - based universe and had to combine their powers to defeat a common enemy. This would involve a lot of character development as they learn to work together.
One idea could be exploring the backstories of the other cyborgs in more detail. For example, what was their life like before becoming a cyborg? Another could be a time - travel plot where Cyborg 009 goes back to change a crucial event in the past that affected all the cyborgs. Maybe a story about how they interact with normal humans in a world that is starting to accept them more, and the challenges that come with that.
Maybe there's a story where an alien force infects Cyborg's systems and Beast Boy has to turn into various animals to find a cure. Along the way, they have deep conversations about what it means to be different. Cyborg feels like he's more machine than man at times, and Beast Boy, with his animal forms, also has an identity crisis. They help each other come to terms with who they are.
One possible plot twist could be that their kiss is part of a spell gone wrong. Maybe they were trying to combine their powers to defeat a powerful enemy, and the magic misfired, resulting in an unexpected kiss. This could lead to a series of comical and confusing events as they try to figure out how to reverse the spell without losing their newfound closeness.
Maybe a plot where their relationship changes and develops because of the pregnancy. They could start off as just friends or comrades and then become closer as they navigate the pregnancy together. There could be a lot of emotional growth and self - discovery for both characters.
Another plot could involve Danny being sent to Raven's world by accident. He has to figure out how to get back home while Raven is initially suspicious of him. But as they start to understand each other's powers and the threats they face in their respective worlds, they form an alliance. They could then team up to stop a powerful enemy that is planning to invade both their worlds.
The OC could be a lost traveler who stumbles upon Raven's hideout. Raven at first is cautious but then decides to help the OC find their way back home. Along the way, they encounter various obstacles like a group of bandits or a magical storm. As they face these challenges, they develop a bond. Another plot is that the OC is a healer who comes to a place full of injured people. Raven is one of the wounded and the OC's gentle and kind nature makes Raven open up in a way she hasn't before. However, there is a group that wants to stop the OC from healing people for their own evil purposes, so Raven and the OC have to fight back.
