Who could be the main antagonists in 'Vegeta and Bulma baby fanfiction'?

Frieza or his remnants could be antagonists. They might see the unborn child as a potential threat in the future, especially if it has strong Saiyan powers. So they could plan to attack Bulma to prevent the birth.

Sometimes new, original antagonists are created for dark fanfiction. They could be powerful demons or shadowy figures from Vegeta's past on Planet Vegeta. These antagonists might have vendettas against Vegeta and see harming Bulma as a way to get revenge. They can bring in elements of mystery and horror to the story.

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.

Cell could also be an antagonist. He has an interest in powerful Saiyan genetics. The baby, being related to Goku, would be of great interest to him. He might try to absorb the baby to gain even more power, creating a big conflict for the heroes to deal with.

Perhaps it could be the school bully. This bully might be jealous of Vegeta's strength and popularity among some students, and also of Bulma's intelligence and charm. So, he tries to create problems between them, like spreading false rumors or trying to sabotage their school projects.

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.

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.

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.

Well, Vegeta himself could be seen as the antagonist in the beginning. Since he is the one doing the kidnapping, he's causing distress to Bulma. However, as the story progresses, the real antagonist could turn out to be someone else. For example, another alien race that is after Vegeta and uses Bulma as bait to lure him into a trap. So, it's not so straightforward in a fanfiction.

Another character could be Dr. Briefs, Bulma's father. In the alternate universe, he might have a more prominent role in bringing Vegeta and Bulma together. For example, he could be the one who arranges for Vegeta to work on a project with Bulma, which starts their relationship on a more professional note that gradually turns into something more personal.
