Power is a common theme. As the dark prince, Vegeta often struggles with the pursuit and control of power. Another theme is redemption. Many fanfictions explore whether he can overcome his dark side.
The main characters are obviously Prince Vegeta and Bulma. Vegeta is the Saiyan prince, known for his pride and combat skills. Bulma is the brilliant scientist on Earth. In this fanfiction, their relationship is often the central focus, with all their differences and similarities playing important roles.
One popular 'Prince Vegeta loves Bulma' fanfiction might be 'Vegeta's New World' where it explores their relationship in a different Dragon Ball universe setting. It shows how Vegeta's love for Bulma changes his character in unique ways.
In such a fanfiction, one possibility is that Vegeta and Bulma could have an adventure together. Maybe they explore a new planet and face some unknown threats. Vegeta's combat skills combined with Bulma's intelligence would make them a great team.
One interesting plotline could be Vegeta trying to understand human emotions while being in a relationship with Bulma. For example, he might struggle with expressing his love in a way that Bulma can understand. Another could be them facing challenges together, like threats from other villains that target their relationship or family. And there could also be a plotline where Vegeta has to adapt to Earth's culture more deeply because of his relationship with Bulma, which includes things like participating in Earth's holidays or social events.
There's also 'Vegeta: The Dark Prince's Redemption'. This fanfiction focuses on how Vegeta, as the dark prince, tries to find a path to redemption. It's interesting because it shows a different side of him, not just his power - hungry and dark aspects, but also his capacity for change and self - reflection.
People like these fanfictions because it's an interesting take on the relationship between two very different characters. Vegeta is a proud Saiyan warrior and Bulma is a brilliant human scientist. Their relationship has a lot of potential for drama and romance.
Frieza could be a great main villain. Since he has a history with Vegeta, his appearance could add a lot of drama. He might try to get revenge on Vegeta or use Bulma as a hostage to force Vegeta to do his bidding.
The plot of Vegeta and Bulma together appeared in Dragon Ball GT. In the Dragon Ball GT-Series, Vegeta and Bulma became a pair of lovers. They experienced many adventures together and solved many problems together. However, they did not officially get married in the manga. Instead, they chose to get along as friends.
