Another plot could involve an accident in the Titans' Tower. For example, a malfunction in some of their training equipment causes harm to both Raven and Beast Boy. Their friends would then have to figure out how to help them while also dealing with the potential danger of the malfunction spreading. This would also show the bond between all the Titans as they come together to take care of their injured comrades.
One idea could be that they are hurt during a battle with a powerful new villain. Maybe they underestimate the enemy's strength and end up with physical injuries. This could lead to them having to rely on each other more for support and also force them to confront their own weaknesses.
Perhaps they are hurt in an emotional sense. They could be betrayed by someone they thought was a friend, which deeply wounds them. This would cause them to question their judgment and their relationships. It could lead to a journey of self - discovery for both of them as they try to heal from the emotional pain and learn to trust again.
In many Beast Boy and Raven fanfictions, Beast Boy's act of protecting Raven is quite common. When he gets hurt in the process, it often adds a layer of drama. Maybe he takes a blow meant for Raven during a battle with a powerful villain. This could lead to Raven realizing her deeper feelings for him as she tends to his wounds.
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.
In a story, there could be a situation where a magical curse is spreading. Beast Boy, seeing Raven in the path of the curse, uses his own body to block it. As a result, he is infected by the curse which starts to harm him physically and mentally. Raven then embarks on a journey to find a cure, all the while taking care of Beast Boy and their relationship deepens through this difficult time.
One plot idea could be that they accidentally get pregnant due to some sort of alien or magical mishap. For example, a strange alien device that was meant for something else malfunctioned and caused Starfire to become pregnant. Another idea is that they decide to have a baby as a way to bring their two different cultures (Tamaranian and Earth) closer together. They could face challenges from their friends and family who might not be ready for them to become parents at such a young age.
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.
A plot could involve a new villain who targets their relationship. This villain could create illusions or situations that make Raven and Beast Boy question their feelings for each other. But as they fight through these false obstacles, they actually end up realizing that their love is stronger than they thought. For instance, the villain might make Raven think that Beast Boy is only interested in her because of her powers, but Beast Boy then shows his true self and his genuine love for her beyond any powers or abilities.
One possibility is that it could show their relationship evolving further. Maybe it starts with Beast Boy finally mustering the courage to propose in a really unique and funny way, like turning into different animals to create a grand proposal scene. Raven, initially hesitant due to her reserved nature, eventually says yes. Their married life could involve them facing new threats together as a married couple, with their love strengthening them even more against the villains.
Perhaps there is a magic user who wants to capture Raven for her powers. Beast Boy tries to stop the magic user and ends up getting hurt. This could be a situation where the magic user casts a spell that Beast Boy tries to absorb or deflect to protect Raven. His injury then becomes a significant part of the story as Raven has to figure out how to save him and deal with her feelings for him at the same time.
She would likely feel guilt. Since Beast Boy got hurt protecting her, she would blame herself to some extent for putting him in that dangerous situation.
One idea could be a story where Raven, Beast Boy and Terra go on a quest together to save their world from a new, powerful enemy. Along the way, Raven and Beast Boy's relationship could be explored more deeply, while Terra struggles with her own powers and how she fits in with the group.
