There could be. Fanfiction is a creative space where all kinds of wild ideas are explored. However, this particular concept seems rather unorthodox considering Gohan's relationship with Bulma in the original Dragon Ball series. Gohan has always seen Bulma more as an aunt - like figure. But in the world of fanfiction, anything is possible. It might be difficult to find though, as it may not be a popular or widely - accepted concept.
There may be such fanfics in the vast world of fan - created content, but it often goes against the original storyline's intended relationships in the Dragon Ball series. In the official story, Goku is married to Chi - Chi, not Bulma.
It would be a major deviation from the original Dragon Ball lore. The characters' relationships are well - established in the official story, and such a fanfic would re - define those relationships in a very extreme way.
Yes, there might be some fanfictions with this concept that are written in a family - friendly way. Some authors may take this idea and turn it into a story about friendship and unexpected situations without going into inappropriate content. For example, they could focus on how the characters deal with the shock and the changes it brings to their relationships in a more humorous or light - hearted manner.
In a 'Vegeta gets Bulma pregnant fanfiction', perhaps it starts with a big event that makes Vegeta realize how much he values Bulma. This leads to them becoming closer and soon Bulma is pregnant. The story could then focus on how Vegeta's Saiyan pride affects his reaction. He might be initially shocked but then become super protective. And Bulma, being the smart and strong - willed woman she is, would be preparing for the baby while also dealing with Vegeta's sometimes over - the - top reactions.
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.
A 'Gohan Gets Bulma Pregnant' fanfiction would likely be a very different take on the Dragon Ball universe. It would probably have to rewrite a lot of the character backstories and relationships. For example, it would need to explain how Gohan and Bulma's feelings for each other developed, as in the original they are more like friends or family. It could potentially introduce new elements like a new enemy or a prophecy that forces them together. However, it would be hard to make it fit well with the overall tone and lore of Dragon Ball.
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.
Perhaps there could be a time - travel plot. In the future, Bulma's grandchild (from Vegeta) discovers a way to go back in time. But something goes wrong during the time - travel, and it causes a strange energy reaction that makes it look like Goku is the father of Bulma's baby. Goku and Bulma then have to work together to figure out what happened and how to fix it. They go on a journey, facing challenges and meeting old enemies, all while trying to keep this strange situation a secret from their friends. In the end, they are able to correct the time - line and the false pregnancy situation.
Well, in such a fanfiction, Bulma might start acting really out of character. She could say things she normally wouldn't, like sharing her deepest secrets or making really bold statements. Maybe she'd start dancing in a silly way or trying to do things she's not good at, like singing karaoke really badly.
