Typically, Vegeta's character growth is a big part of how their relationship progresses. As Bulma is pregnant, he begins to see the importance of the family he's creating. He might train less rigorously to be around more for Bulma. This new dynamic makes their relationship more complex and loving, with them depending on each other more and learning to compromise.
Their relationship would likely become more intimate and committed. With a baby on the way, Vegeta would probably be more protective of Bulma. He might show his love in more practical ways, like making sure she has everything she needs.
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.
At first, it might be a relationship based on mutual need. Vegeta needs Bulma's resources and intelligence to get back on his feet, and Bulma is intrigued by this alien. As time passes, they start to understand each other better. For example, Vegeta may start to open up about his past and his Saiyan pride, and Bulma will share her dreams and ambitions with him.
Well, in fanfiction, it often starts with some unexpected encounters. Maybe Vegeta gets injured and Bulma has to take care of him. During this time, they start to see different sides of each other. Bulma realizes that Vegeta isn't just a cold - hearted warrior, and Vegeta sees Bulma's kindness and strength. Their relationship then builds as they have more conversations. They argue at first, but these arguments lead to a better understanding, and love starts to bloom from there.
In other fanfictions, external factors play a big role in their relationship development. For example, if there is a new threat to Earth and Vegeta and Bulma are part of the team to defend it. Working together towards a common goal, they start to understand each other better. Vegeta begins to appreciate Bulma's importance not just as his partner but also as a key member of the group protecting their home, and this deepens their bond.
In some fanfictions, their relationship starts with tension. Majin Vegeta is full of new power and a different mindset. But Bulma, being the strong - willed woman she is, doesn't back down. This leads to a mutual respect which can then develop into something more romantic over time.
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.
Well, their relationship starts off rocky. Vegeta is this proud Saiyan warrior, and Bulma is a smart, sassy Earthling. At first, they clash because of their different personalities. But over time, they start to see each other's good points. Vegeta begins to respect Bulma's intelligence, and Bulma starts to understand Vegeta's tough exterior is hiding a more complex person. This gradual change in their perception of each other paves the way for their relationship to develop to the point of a kiss.
In some fanfictions, their relationship develops through shared experiences. They might go on adventures together, and during those times, they get to know each other better. Vegeta might open up about his past, and Bulma might share her dreams for the future, which deepens their bond.
At first, their relationship might start with a mutual respect for each other's abilities. Vegeta respects Bulma's intelligence as she is a brilliant scientist. Bulma, on the other hand, respects Vegeta's power. As time passes, they start to rely on each other more. Vegeta might rely on Bulma for technological support, and Bulma might rely on Vegeta for protection. This gradually turns into deeper feelings as they spend more time together and face challenges as a team.
