A potential plot twist could be that Raven's demonic side resurfaces in a way that endangers their marriage. Maybe it's triggered by an external force, and she starts to push Beast Boy away for his own safety. Another twist could be that Beast Boy gets a strange new power that he can't control, and it causes some friction between them as they try to figure out how to deal with it.
One interesting plot twist might be that an old enemy of the Teen Titans returns and tries to use their marriage against them. This enemy could try to brainwash one of them to turn against the other. For example, they might make Beast Boy believe that Raven is using him for her own dark purposes. Or perhaps a new character enters the scene who claims to be related to Raven and has a different view on their marriage, causing internal conflict within the couple.
Well, Raven and Beast Boy are the main characters. Raven, with her dark and mysterious aura, brings a sense of depth to the story. Her powers are not only for fighting but also for protecting her new family with Beast Boy. Beast Boy, being able to change into animals, adds an element of fun and unpredictability. Their relationship forms the core of the fanfiction, and other characters from their universe may play supporting roles in their married life story.
A great plotline could involve them having to combine their powers to protect their home or a new family member. Since Raven has her dark magic and Beast Boy can transform, they could create unique defenses. Also, they might have cultural differences to overcome, as Raven has her more somber and mysterious background while Beast Boy is more light - hearted. This could lead to some comical and also heart - warming moments in the fanfiction.
One possibility is that the story focuses on how Raven and Beast Boy adjust to being parents. They might face difficulties like protecting their baby from villains who want to use the baby's powers for evil. The baby could also be a key to uniting different factions in their world, so there would be a lot of political intrigue around it as well.
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.
In a fanfiction, it might start with a slow - building tension between Beast Boy and Raven. They could be in a situation where they are forced to be close, like being trapped in a small space. Beast Boy, being the more impulsive of the two, finally gives in to his attraction and kisses Raven on the neck. This then sets off a chain of events where they have to deal with their new - found physical and emotional closeness, as well as how their friends will react.
Perhaps they get trapped in a magical realm where emotions are heightened. Raven, who usually keeps her feelings in check, can't resist the pull towards Beast Boy in this strange place and they kiss. This could then lead to a struggle when they return to normal as they try to figure out if those feelings were real or just a product of the magic.
The plot could involve Raven feeling more isolated than usual and retreating into her 'lonely beast' form. Beast Boy, noticing this, decides to try and help her. He might start by just being around her, and gradually they start to communicate more. Eventually, they could face a common enemy together while Raven is still in that form, and their combined efforts lead to a stronger relationship.
Another plot twist might be that the kiss is witnessed by the other Titans, and they all have different reactions. Some are supportive, while others are worried about how it will affect the team dynamic. This then creates a whole new set of challenges for Robin and Beast Boy to face in their relationship.
A fanfiction could also focus on their relationships outside of being superheroes. They could be having a normal day at the Tower, just hanging out. Starfire could be trying to cook something new from her home planet, Raven could be reading a book in the corner, and Beast Boy could be cracking jokes, which at first annoys Raven but then she starts to laugh.
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.
