One common theme is the growth of Vegeta as a character within the family. He goes from a battle - obsessed Saiyan to a loving father and husband. Another theme is the cultural clash between Saiyan and Earthling ways. And of course, the love and attraction between Vegeta and Bulma, which overcomes their initial differences.
In 'dbz vegeta x bulma' fanfiction, their romance is often depicted as a slow - burning yet intense one. Vegeta, initially a proud and somewhat cold Saiyan, gradually warms up to Bulma. Their family life is full of interesting dynamics. Trunks is a key part of their family, and the stories might explore how Vegeta becomes a better father and husband over time.
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 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.
Well, family is a big theme. They have a son, Trunks, and many fanfictions explore how they raise him together. There's also the theme of self - discovery. Vegeta discovers a softer side of himself through his relationship with Bulma, and Bulma learns more about strength and determination from Vegeta. And of course, the theme of loyalty, both to each other and to their friends and family in the Dragon Ball universe.
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.

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.
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 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.

Another theme could be the exploration of boundaries in relationships, as stalking is an extreme behavior that crosses normal relationship boundaries.
One common theme could be Vegeta's struggle to understand his feelings for Bulma. Since he is a Saiyan warrior not used to such emotions, his obsession might manifest as a mix of protectiveness and confusion. Another theme might be Bulma's influence on Vegeta's character development. For example, she might be the one to soften his rough edges, and his obsession could be related to how much he needs her in his life.
