There could be a new vampire hunter in town. This hunter could target Stefan and Elena because of their relationship. He might believe that their union will create a more powerful vampire line and wants to stop it before it's too late.
In a small, idyllic town, Stefan and Elena decided to have a simple yet beautiful wedding. The ceremony was held in an old church surrounded by lush greenery. Elena walked down the aisle in a white lace dress, her eyes only on Stefan. Stefan, looking dashing in his suit, couldn't hold back his tears of joy. Their friends and family watched as they exchanged vows, promising to love and cherish each other forever. After the ceremony, they had a reception in a garden filled with flowers. They danced under the stars, knowing that their love had finally led them to this perfect moment.
Love and commitment are very common themes. Since they are married, the fanfictions often explore how they stay true to each other in the face of various difficulties. For example, in many stories, they have to deal with threats from other supernatural beings but their love remains unshaken.
There could be new antagonists created specifically for this fanfiction. For example, an evil scientist who is jealous of Bulma's intelligence and wants to steal her inventions. This new villain could team up with other existing villains in the Dragon Ball universe to create chaos and try to break up Goku and Bulma's marriage.
Another great one is 'Elena and Stefan: A Married Love Story'. It focuses on the simple yet beautiful aspects of their marriage. It shows how they celebrate small things like anniversaries and birthdays. The author has a great way of writing their dialogues, making it feel very natural and in - character for both Elena and Stefan.
Another plot could be them starting a new business in Mystic Falls. They have to deal with the local politics and the jealousy of some of the townspeople who are still not used to their relationship. This would create a lot of drama and also show how they support each other through tough times.
It could be that an old enemy of Stefan's family decides to target Bella as a way to get back at Stefan. This enemy might be another vampire clan or a supernatural being with a long - standing grudge. They would do everything in their power to disrupt the relationship between Bella and Stefan, causing all sorts of problems and conflicts for the two of them in the fanfiction.
The Mikaelson family, especially Klaus, could be antagonists. He might see the pregnancy as a threat to his family's power or reputation. He could try to stop Stefan and Rebekah from being together and having the baby.
Elena would likely be angry. She has her own agency and doesn't like being controlled. If Stefan kidnapped her, she would fight back. She might use her knowledge of the supernatural world and her relationships with other characters to try to escape. For example, she could try to call out to Damon telepathically if they have some sort of connection in the story.
The other vampire clans might be antagonists. They could see the baby as a threat to the vampire hierarchy or fear that the baby will have powers that could disrupt the balance among vampires. For example, the Originals' siblings who don't trust Kol might try to stop Elena from having the baby.
The other vampires in Mystic Falls who are against the idea of a hybrid - vampire baby could be antagonists. They might see it as a threat to their way of life.
