The plot might involve Bulma creating a new device that has some unexpected side effects. Gohan then comes to help her fix it. Along the way, they might encounter some old enemies or new threats. And perhaps through this experience, they develop a deeper understanding and friendship. For example, Bulma could be working on a time - travel device and accidentally sends them both to a different era, where they have to rely on each other to get back home.
Maybe in this fanfiction, Bulma creates a new device that has an unexpected side effect on Gohan. It could start to make him see Bulma in a different light. They then go on adventures together, facing various threats. As they fight side by side, their relationship blossoms. Gohan starts to realize that Bulma is not just an old family friend but someone he has strong romantic feelings for.
They could have a mentor - mentee relationship. Gohan, being a powerful Saiyan, could teach Bulma about the Saiyan ways, like their fighting techniques and their strong sense of honor. Bulma, in turn, could mentor Gohan in science and technology, which would be useful for Gohan in his battles.
Well, it could be about Bulma being betrayed by a close friend in the Dragon Ball universe. Maybe that friend reveals her secrets to an enemy, like her latest inventions or the location of the Dragon Balls she was guarding. This would put her in a dangerous situation and lead to a series of adventures where she has to fix the mess.
It's interesting because it allows for new storylines in the Dragon Ball world. Since Gohan and Bulma don't have a typical romantic or overly close relationship in the original series, fanfics can explore uncharted territory. For example, they could go on adventures together, solve mysteries, or support each other in ways that we don't see in the main story. It gives a fresh perspective on the characters and the Dragon Ball universe as a whole.
Well, in a fanfiction, their relationship could be one of mutual respect. Gohan, being a powerful warrior, might turn to Bulma for her technological expertise. Maybe Bulma could create new training equipment for Gohan. And Gohan, in return, could protect Bulma's research facilities from any threats. It could also be a more of a mentor - mentee relationship in some aspects, with Bulma guiding Gohan on how to use some of her inventions effectively in combat situations.
A possible plot twist could be that Gohan discovers a hidden power within himself because of his relationship with Bulma. Maybe her scientific experiments accidentally trigger something in his Saiyan genes. Another twist could be that their marriage is part of a bigger plan by an enemy to disrupt the Z - fighters. The enemy might think that by causing this strange union, they can create chaos among the group.
In a fanfic, the Bulma - Chichi fusion could be part of a tournament arc. They enter the tournament fused and shock everyone with their abilities. Their opponents underestimate them at first, thinking it's some kind of strange trick. But as the battles progress, they show that their fusion is not only powerful but also has a deep understanding of both martial arts and strategic thinking.
Well, the plot could involve them fusing due to some kind of magical or technological accident. Maybe they are trying to defeat a powerful enemy together and their combined energy causes them to fuse. They could then have a new form with combined powers and a unique personality that is a blend of their own.
Perhaps Bulma wishes for a boyfriend who can understand her scientific pursuits. In the fanfic, she could find someone who is also a brilliant scientist from another planet. They start collaborating on projects together, and as they work closely, feelings develop. But there are obstacles. Their different cultures might clash, and there could be other characters who are envious of their relationship. For instance, some of Bulma's rivals in the scientific community might try to sabotage their relationship to get ahead in their research.
One possible plot could be that Bulma and Chichi team up for a scientific - martial arts tournament. Bulma uses her intelligence to create unique gadgets for Chichi to use in the combat part of the tournament. This brings them closer as they train together and face various opponents.
