Well, fanfics can be very diverse. While the idea of Bulma cheating on Vegeta with Goku seems quite outlandish when considering the original story, in fan - created works, anything is possible. Some fanfic authors might want to create a shock factor or a new take on the relationships. But it's important to remember that this is not in line with the core values and relationships presented in the main Dragon Ball series. The main series has always shown Bulma and Vegeta as a couple, and Goku with his own set of relationships.
In some fanfics, there might be such out - of - character scenarios for the sake of creating drama or exploring different relationship dynamics. But in the original Dragon Ball series, this would never happen as the characters have their established relationships and personalities. Bulma is with Vegeta and Goku has his own family and relationships that are very different.
One reason could be to create a huge plot twist. It's a very unexpected and controversial idea that can immediately grab the reader's attention. Another reason might be to explore different emotional states. For example, showing how Vegeta would react to such a betrayal and how Goku would deal with the moral implications of being involved in such a situation.
It often starts with a shock or surprise at the mpreg situation. Then, they gradually learn to rely on each other more. For example, Vegeta might start to show a more caring side that he usually hides, and Goku might become more responsible. They'll have to communicate more, sharing their fears and hopes about the future with the baby.
One interesting plotline is when Bulma's inventions are used to enhance Goku and Vegeta's powers in unique ways. For example, she might create a device that helps them control their ki better. Another is when Goku and Vegeta have to work together to protect Bulma from a new and powerful enemy. It shows their growth as characters who can put aside their differences for someone important to them.
It can create tension. The readers will be curious about how Vegeta will react and if he can fix the situation. This keeps them engaged in the story.
The development of their love also has to do with how they handle their differences. Vegeta's pride as a Saiyan can sometimes clash with Bulma's more emotional and outspoken Earthling nature. But in fanfics, as they work through these clashes, they learn more about each other and their love grows. It's like a journey of self - discovery and relationship - building at the same time.
In some fanfictions, it might be a really strange and unique concept where Goku is depicted as Vegeta's pet. But this is far from the original relationship in the official Dragon Ball story. It's just a creative and often humorous take that some fanfic writers explore.
One great Bulma, Goku and Vegeta fanfic is 'A New Adventure'. It explores their relationships in a different way. It shows how Bulma's intelligence, Goku's strength, and Vegeta's pride interact in unique situations. Another is 'The Trio's Bond'. This fanfic delves deep into their friendship and how they support each other during tough times. There's also 'Bulma's Influence' which focuses on how Bulma affects Goku and Vegeta's development as characters.
The relationship might develop gradually. Bulma could start by being attracted to Vegeta's power and mystery. As she gets closer to him, she discovers his more complex personality. Vegeta may initially resist her advances but eventually gives in to his own feelings.
In such fanfiction, Vegeta might make Bulma happy by showing his softer side. Maybe he cooks a special meal for her. Vegeta is often portrayed as tough, but when he does something out of his usual character like cooking, it can be a sweet surprise for Bulma.
In the fanfiction, their relationship could be explored by showing how they adapt to each other. Vegeta's feral side might require Bulma to be more patient and understanding. And Bulma's needs might force Vegeta to become more domesticated in some ways. For instance, he might have to learn to control his temper around her family and friends. It could also show how their relationship evolves over time, starting from initial attraction despite their differences to a deep, loving bond that endures through various challenges.
