You could have the new boyfriend be a rebel from a different planet. He's fighting against an evil regime, and Bulma gets involved in his cause. Their relationship grows as they fight side by side. Or, he could be a super - intelligent scientist like Bulma. They meet at a research project and start dating. Their relationship could be filled with intellectual debates and shared scientific discoveries.
A great idea for a Bulma new boyfriend fanfic is to make the new boyfriend a musician. He plays otherworldly music that has a strange effect on Bulma. They bond over their love for music, and he helps her relax from her usually busy and scientific life. Also, you can make him a bit of an outcast, which makes Bulma want to protect him and their relationship becomes a story of acceptance and love.
Well, think about the setting. It could be in a futuristic city. For the new boyfriend, give him some interesting hobbies like collecting ancient artifacts from different planets. In the fanfic, show Bulma's initial reaction to him, whether it's curiosity or instant attraction. Then, build their story around shared interests and how they overcome obstacles in their relationship.
The plot could be that Bulma starts dating a new guy who is from a different planet or something really exotic in the Dragon Ball universe. Her old friends are a bit skeptical at first. Then, one of her male friends, like Yamcha who she has a history with, comes back into the picture. The new boyfriend sees how Yamcha and Bulma interact casually and gets jealous. He starts to act out, which causes problems in his relationship with Bulma.
Well, start with a great opening scene that introduces Bulma and her new beau. To bring in jealousy, you could have the new boyfriend notice how Bulma still has mementos from her past relationships around. This could trigger his jealousy. As for the fanfic part, make sure to keep the tone in line with the Dragon Ball universe. Include some of the other characters' reactions too. For example, Goku might be oblivious while Vegeta scoffs at the whole situation.
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.
A third idea could be a story centered around a tournament. Naruto, Bulma and 21 all enter a tournament for different reasons. Naruto wants to prove his strength, Bulma wants to test some of her new inventions in a combat - like situation and 21 is there because she has no choice. During the tournament, they end up having to team up against a powerful opponent and discover new things about themselves and each other.
One great alternative could be a fanfic about Bulma's scientific achievements. She's known for her intelligence and her inventions in the Dragon Ball series. You could write about her creating a new amazing device that helps the Z - Fighters in a battle. Another idea is a fanfic focusing on her relationship with Vegeta. How they interact, support each other, and grow as a couple. It could show their domestic life or how they handle challenges together.
In the fanfic, Yamcha could be her ideal boyfriend again. They have a history together, and in this new story, they could rekindle their relationship. Yamcha has become more mature and has learned from his past mistakes. He could now support Bulma in her scientific endeavors and be a more reliable partner. He also has some combat skills, which could come in handy when they face threats together in the Dragon Ball world.
One idea could be that Bulma, while doing some research in a far - off planet, accidentally stumbles upon Broly. At first, Broly is hostile as he's used to being feared. But Bulma, being the smart and fearless woman she is, tries to communicate with him using her tech gadgets. She shows him things from Earth, like pictures of her family and friends. This makes Broly curious about Earth and he decides to follow Bulma back to Earth, leading to a series of adventures as he tries to adjust to this new world and protect Bulma from other threats.
Maybe there's a plot where Beerus has a premonition about a threat to the universe that only Bulma's technology can help prevent. So, he has to team up with her. Along the way, they learn more about each other's worlds. Bulma gets to understand the power and responsibilities of a god like Beerus, and Beerus discovers the amazing potential of Earthling technology. This could lead to a deeper friendship or mutual respect between them.
One plot could be that Roshi enters a cooking competition, and Bulma decides to help him out using her scientific approach to cooking. They combine Roshi's traditional recipes with Bulma's high - tech cooking gadgets and create amazing new dishes. Along the way, they face off against other competitors who are jealous of their unique approach. Another idea is that a strange alien race kidnaps Roshi, believing he has a powerful energy within him. Bulma uses her intelligence and resources to track him down and rescue him. During the rescue mission, they learn more about the alien race's motives and end up befriending some of the aliens who were against the kidnapping in the first place.
