One interesting plot line could be how Vegeta overcomes his pride for the sake of his love for Bulma. For example, he might start doing small, uncharacteristic things like buying her flowers or cooking for her, which are things he would never have considered before. Another could be their journey through Bulma's pregnancy with Trunks. Vegeta might struggle with being a father while also dealing with his Saiyan warrior nature.
One interesting aspect is the contrast between Vegeta's tough Saiyan nature and Bulma's more earthly and emotional human side. Their love often shows how two very different personalities can come together. For example, Vegeta's initial pride and aloofness gradually gives way to a deeper emotional connection with Bulma. This transformation is a key part of their relationship in fanfiction.
Perhaps a plot where Bulma creates a new invention that goes wrong and accidentally gives Vegeta some strange powers. They then have to figure out how to reverse it while also dealing with their feelings for each other. It could involve some comical situations as Vegeta tries to control these new powers and Bulma tries to help him, all while their love story unfolds.
Perhaps a fanfiction where Bulma, out of curiosity, tries to understand the cultural and biological importance of Vegeta's tail. She starts documenting it, and Vegeta is initially hesitant but then realizes it's a way for her to get closer to his Saiyan heritage. This could lead to some really sweet and funny moments between them as she asks all sorts of questions about it and he tries to answer them in his gruff way.
Perhaps the fanfiction could focus on how the baby's Saiyan heritage affects its growth and development. For example, it might have a very strong appetite like Vegeta, or it could show signs of intense determination early on. Also, it could be interesting to write about how Bulma uses her scientific knowledge to ensure the baby's well - being while also dealing with Vegeta's Saiyan parenting ideas.
One plot point could be Bulma getting pregnant again and Vegeta being overly protective. He might not let her out of his sight, which leads to some comical situations as Bulma is used to her independence.
Well, a story could be set during a time when Bulma is pregnant with their second child. She's having a difficult pregnancy, and Vegeta has to learn to be more supportive and understanding. This could lead to some really sweet and also some tense moments between them. They could also have an adventure together during this time, like trying to find a special herb on a far - off planet that's supposed to help with the pregnancy.
A great plot could be how their relationship affects the rest of the Dragon Ball gang. Goku might be a bit confused at first, and Chi - Chi could be either supportive or a bit jealous. And then there's the whole dynamic of Vegeta becoming more involved in Earth - based family life, which is a huge change for him.
One possibility is that at first, Vegeta is completely oblivious to Bulma's feelings. But as time goes on, Bulma's consistent presence in his life makes him realize he has feelings for her too. Their relationship could develop through shared goals, like protecting the Earth from new threats.
One possible plot could be that Vegeta and Bulma's relationship deepens over time. They might face challenges together, like threats to their family or the planet. Their love could be a source of strength for Vegeta, making him more protective and also more in touch with his emotions.
One interesting aspect is how Vegeta, who was initially a tough and prideful warrior, softens up because of Bulma. His character development in fanfics often shows him learning to express emotions like love and care, which is a big change from his original self.
