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.
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.
Another common plot is the 'time - travel' scenario. Given the time - travel elements in DBZ, some fanfictions might send Vegeta or Bulma back in time. This can lead to interesting situations where they have to interact with their younger selves or change certain events in the past. It also gives a chance to explore their relationship in a different timeline.
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.
There is a fanfiction called 'Baby Vegeta's Training'. In this, it details how baby Vegeta, despite his small size, still tries to train and become stronger. It's interesting as it gives insights into his character and his unwavering determination to be the best, even as a baby.
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.
Bulma's pregnancy in fanfiction could also bring out different aspects of their relationship. They'll likely have more tender moments. Maybe Vegeta will start to share his Saiyan traditions with Bulma regarding child - rearing. And Bulma will introduce him to more Earthling - style family values. This exchange can be really interesting to explore.
One great 'dbz female vegeta fanfiction' is 'The Female Saiyan's Ascent'. It shows a female Vegeta with unique character development, facing challenges in the Dragon Ball Z universe. She battles not only the external foes but also her own insecurities.
A lot of 'dbz goku x vegeta fanfic' has the theme of redemption. Vegeta, in particular, has a complex past, and in these fanfics, his relationship with Goku can be a part of his path to redemption. Also, the theme of family is present as they both have families and their interactions can be influenced by their family values. There's also the overarching theme of the Saiyan pride that they both carry and how it affects their relationship.
One common theme is rivalry - turned - friendship. Their initial intense rivalry gradually transforms into a deep bond as they face various threats. Another theme is power - up. They often find new ways to increase their power together, like in some fanfictions where they discover a new fusion technique.
