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 idea could be a story about Bulma's inventions and how Baby Trunks gets involved in her experiments. For example, he could accidentally activate a device that sends them on an adventure through time or to a different dimension.
In a fanfic scenario, 21 could be in trouble and Naruto and Bulma come across her. Naruto, with his heroic nature, would immediately offer help. Bulma, on the other hand, would assess the situation from a scientific perspective. She might try to figure out if 21's situation is related to some new technology or energy. As they work together to help 21, they also have to deal with other threats that are attracted to 21's unique situation.
One idea could be a crossover where Bulma's technology is used in the Naruto universe. For example, she could create some new kind of ninja tools with her advanced knowledge. Maybe she helps the Hidden Leaf Village upgrade their defense systems. It would be interesting to see how the Naruto characters react to her and her inventions.
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.
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.
Sure. A lot of fanfic writers like to create stories that bring together characters from different anime. They might write about Naruto and Bulma meeting at a multi - universe gathering or something like that. It can be a really interesting concept to explore their different powers and personalities interacting in a family - friendly setting.
One plot idea could be that Bulma creates a special device that can transport Naruto to the Dragon Ball universe. There, Naruto has to learn to use ki instead of chakra and teams up with Bulma to stop a new threat that is endangering both universes. Another idea is that Bulma discovers a way to combine the technology of her world with the ninja techniques of Naruto's world. This could lead to some really cool inventions and battles. A third plot could involve Bulma accidentally getting sent to the Naruto universe and Naruto has to protect her while she tries to find a way back home. Along the way, Bulma could introduce some of her scientific knowledge to the ninja world, which would change things in unexpected ways.
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.
