The fact that they have a family together also has some secrets. For instance, how they decided on the names for their children. There could be hidden meanings or stories behind those names that are like little secrets. Also, their family life is a blend of Saiyan and Earthling cultures, and the little ways in which they navigate those differences and make it work might be considered as secrets of their relationship. For example, how they handle Trunks' Saiyan powers while also making sure he has a normal Earthling upbringing.
One little secret could be the way Vegeta slowly warms up to Bulma's family. At first, he seems so aloof, but over time, he starts to care about them in his own way.
Sure. One interesting secret could be that Bulma has a collection of mementos from their early days together, like a small piece of cloth from Vegeta's Saiyan armor when he first came to Earth. Vegeta doesn't know about this collection, and it's a sweet secret that shows Bulma's sentimental side.
A possible secret could be that they both have a shared dream for their family that they haven't told anyone else yet. They might be planning a future for their son Trunks in a very specific way, like sending him to a particular school in the future. This is a secret they keep between them as they don't want others to interfere or know their long - term plans for their family.
In DBZ Vegeta and Bulma fanfiction, there can be alternate universes explored. Maybe in one universe, they meet under different circumstances. For instance, instead of Vegeta coming to Earth as an enemy, he could be an ally from the start. This would completely change the dynamics of their relationship. It could lead to a more romantic and less combative start to their relationship, and the fanfiction could explore how this different beginning affects their future together.
In Vegeta and Bulma fanfiction, a great part is seeing how their different personalities mesh. Vegeta is all about power and pride, while Bulma is intelligent and resourceful. Fanfictions might show how they balance each other out. For instance, Bulma could use her smarts to come up with strategies in battles that Vegeta is involved in. Also, their cultural differences, Vegeta being from a Saiyan culture and Bulma from Earth, can lead to interesting storylines. Writers can explore how they deal with these differences and grow closer because of them.
One interesting plot could be where Vegeta has to go back to Planet Vegeta in a vision or some sort of time - travel scenario. Bulma, being in love with him, follows him. There, they face the old ways of the Saiyans and have to fight against the traditional norms to be together. It shows how their love overcomes not only the differences in their personalities but also the cultural differences between Earth and Planet Vegeta.
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.
A third fanfiction concept could be about how they prepare for the baby's arrival. Vegeta, not knowing much about Earthling baby things, has to learn. Bulma tries to teach him, and there are a lot of cultural clashes and misunderstandings at first. But as time goes on, they work together to create a perfect nursery and get ready for their new family member.
Perhaps in this fanfiction, there's a lemon - loving alien race in the DBZ world. Bulma, being the curious scientist, wants to study them, and Vegeta is dragged along. Along the way, they face challenges that force them to work together in new ways, and their relationship deepens as they navigate through this lemon - related encounter.
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.
