A plot could revolve around how their relationship changes during the pregnancy. At first, they might be in shock and not know how to react to each other. But as time goes on, they grow closer and start preparing for the arrival of the baby. They could also face opposition from some of their friends or mentors who think that having a baby at this stage in their superhero lives is a bad idea. This would create a lot of drama and character development throughout the fanfiction.
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.
One idea could be that Raven discovers she's pregnant and is initially scared because of her unique powers. Dexter, being the scientific mind, tries to find a way to ensure the baby will be healthy. He starts researching how Raven's powers might affect the pregnancy.
A more complex plot idea could be that there is a prophecy about Naruto and Raven. As Naruto is the little brother, he is initially seen as the weaker one, but as the story progresses, he shows that he has unique qualities that are essential to fulfilling the prophecy. Along the way, they face many enemies who want to stop them from achieving the prophecy's goal. Their relationship evolves from a simple brother - sister bond to a powerful partnership that can change their world.
One idea could be a story where Robin, Starfire and Raven have to team up against a powerful new villain that is immune to their individual powers. They must learn to combine their abilities in a new way. For example, Robin uses his strategic mind to find the villain's weakness, Starfire provides the brute force, and Raven uses her magic for defense and to disrupt the villain's power source.
A plot could revolve around a mystery in Gotham that seems to be related to Raven's dark magic past. Robin, being the detective he is, teams up with Raven to figure it out. Along the way, they discover that there are forces trying to use Raven's powers for evil in Gotham. They have to not only stop these forces but also deal with their growing feelings for each other, which they initially try to hide.
One plot idea could be that Raven discovers she's pregnant in a world full of chaos and has to find a safe place for her unborn child. Maybe she teams up with some unexpected allies who help her on this journey.
One plot idea could be that Raven discovers she's pregnant and is initially in denial. She tries to hide it from the rest of the Teen Titans, especially Beast Boy, because she's afraid of how he'll react. Another could be a more comical take where Beast Boy accidentally finds out before Raven has a chance to tell him, and he goes into over - protective mode immediately. Maybe he starts reading every pregnancy book he can find and trying to cook special healthy meals for Raven, much to her annoyance at first.
One plot idea could be the challenges they face during the pregnancy. For example, how they deal with the changes in their relationship and the new responsibilities. Another could be the reactions of their friends and family to the news.
Another possibility is a fanfiction set in an alternate universe where Raven and Damian are already married and they've been trying to have a baby for a while. When Raven finally gets pregnant, it's a time of great joy. They could go through all the typical pregnancy experiences like shopping for baby clothes, choosing a name, and decorating the nursery.
Well, a plot could involve a mystery in the high school that only Raven and Robin seem to be aware of. They team up to solve it, and during their investigations, they discover secrets about each other that bring them closer. Maybe Raven has some hidden powers that she's been afraid to show, and Robin's detective skills help her come to terms with it. And in the process, a romantic relationship starts to bloom.
