In this fanfiction, the baby might be a key to uniting different factions in the Dragon Ball universe. Since Vegeta has his Saiyan heritage and Bulma is an Earthling, their baby could symbolize a new era of peace and cooperation. The story could show how the baby grows up being adored by all the Z - fighters. Vegeta would be protective and train the baby in secret, while Bulma would be showing off the baby's cute side to her friends. There could also be some comical moments when the baby's Saiyan appetite clashes with Bulma's attempts to feed it a balanced diet.
One challenge could be protecting the baby from their enemies. Vegeta has made many foes over the years, and they might target the baby. Also, Vegeta's Saiyan nature might make him push the baby too hard in training, while Bulma wants a more relaxed approach. This difference in parenting styles could cause some friction between them.
There could be a rogue Saiyan who has different ideals from Vegeta. This Saiyan might think that the baby should be raised in a more traditional, warrior - like way and try to take the baby from Bulma and Vegeta. Or, an evil scientist who wants to experiment on the baby's unique Saiyan - human DNA could be the main antagonist, creating all kinds of challenges for Vegeta and Bulma to protect their child.
As far as I know, no. The idea of 'baby bra' in relation to Vegeta and Bulma seems rather unusual. In the world of Vegeta and Bulma fanfiction, popular stories usually center around things like Vegeta's training, Bulma's inventions, and their family dynamic with Trunks. There's not much indication that a 'baby bra' fanfiction would be well - known.
The story might center around a new threat to the Earth that only their combined efforts can defeat. Vegeta uses his fighting skills and Bulma uses her intelligence to create new gadgets or find weaknesses in the enemy. Along the way, they reaffirm their love for each other and strengthen their family unit.
The plot could start with Majin Vegeta's pride getting in the way. He might feel that Bulma is disrespecting his new power as Majin Vegeta. So, he challenges her to a fight. Bulma initially panics but then decides to stand her ground. She uses her knowledge of Saiyan physiology (from all the time she's spent with Vegeta and the other Saiyans) to find his weak points. However, she also tries to reach out to the real Vegeta inside. As the fight progresses, Vegeta starts to see how strong - willed Bulma is and slowly begins to break free from the Majin influence.
The fanfiction could focus on the challenges they face during the pregnancy. For example, Bulma might have some health scares that make Vegeta worry a great deal. He could struggle with his emotions, not knowing how to handle his fear of losing her or the baby. Also, there could be a sub - plot about how the news of Bulma's pregnancy affects the political situation in the Dragon Ball universe. Some enemies might see it as an opportunity to attack while some allies might offer more support than ever.
One possible plot could be that Vegeta kidnaps Bulma because he believes she has some technology that can help him gain an edge over his enemies. He takes her to a secret location and demands she work on it for him. Bulma, being the feisty and intelligent woman she is, tries to outwit Vegeta at every turn while also gradually getting to know a more vulnerable side of him that he doesn't usually show.
Well, it could be about them exploring a new planet during their honeymoon. Maybe they find some unique and beautiful landscapes, and Vegeta shows his softer side to Bulma as they enjoy the new environment together.
Well, in a fanfiction, Bulma and Vegeta might have some really interesting interactions. Maybe they could go on a unique adventure together, facing challenges that test their relationship. For example, they could encounter a new enemy that forces them to rely on each other's strengths more than ever. Their different personalities, with Bulma's intelligence and Vegeta's pride and power, would create a lot of drama and tension in the story.
I'm not sure specifically about 'baby bra' related fanfictions as it's a rather strange concept. However, there are many great Vegeta and Bulma fanfictions in general. You can try searching on popular fanfiction websites like FanFiction.net or Archive of Our Own. There you might find stories that focus on their relationship, from how they first got together to their family life with Trunks.
