A more character - driven plot could involve a rift between the three. Say, Robin starts to focus more on his solo work, which makes Starfire feel left out and Raven frustrated with his lack of teamwork. The story could be about them mending their relationships. Starfire could confront Robin about his behavior, and Raven could be the mediator, ultimately leading to them becoming a stronger team again.
Another plot could be a time - travel story. Maybe they accidentally get sent back in time and have to figure out how to get back to their own time while also not changing the past too much. Robin could use his knowledge of history to navigate, Starfire tries to adapt to the different time period's culture, and Raven has to keep her powers in check so as not to cause any unforeseen disruptions.
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.
Perhaps a plot where Starfire and Robin get married in a secret ceremony due to security reasons. But then they have to deal with the media finding out and all the chaos that ensues. This could involve protecting their friends and family from paparazzi and supervillains who might want to use the situation to their advantage.
Another plot could be that there's a threat to both Raven and Starfire's families. They have to work together, with their families' support, to defeat this threat. It could be an evil entity that targets both Earth and Starfire's home planet. Through this adventure, their families learn to trust and rely on each other, and Raven and Starfire's friendship deepens into something more like family on a deeper level.
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.
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.
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.
A cool plot idea could be that the child has a unique power that neither Robin nor Raven have. This power could attract the attention of an ancient evil force that was once sealed away. So, Robin and Raven have to team up with their friends to not only protect their child but also the whole world from this new threat.
The comical dynamic is also appealing. Imagine Robin's serious nature clashing with Starfire's naivete and Raven's dry humor. They could get into all sorts of silly situations, like trying to cook together and failing miserably. This kind of light - hearted dynamic can add a fun and relatable aspect to the fanfiction.
A story could be set in a future where the worlds of Marvel and DC have merged. Spiderman and Starfire are part of a new superhero team. They have to deal with the cultural differences between their two groups of heroes as well as face off against new villains created by the merger of the two universes.
Perhaps a story where they are both on a mission to a new planet. On this planet, there are unique challenges like a strange energy field that affects their powers. Starfire and Robin Red have to rely on each other more than ever. They start to see each other in a new light and their relationship evolves from just being teammates to something more romantic. As they explore the planet, they also learn about a new culture that has some interesting views on relationships.
Another plotline could be set in an alternate universe where they are not part of the Teen Titans. Maybe they meet in a different context, like a magical academy, and their kiss is a turning point in their relationship in this new setting. It gives the writers a chance to re - imagine their characters' dynamics without the constraints of the original Teen Titans storyline.
