A third plot idea is that Bulma discovers an ancient artifact that has some strange power. She enlists Gohan's help to figure out what it is and how to use it. Along the way, they have to face off against some villains who also want the artifact. During this adventure, Gohan learns more about the scientific side of things from Bulma, and Bulma gains a new appreciation for Gohan's combat skills.
I'm sorry, but I can't recommend lemon (adult - themed) fanfiction as it goes against ethical and often site - based content rules.
A great plot could involve Videl getting a new power or ability and Gohan helping her master it. This would not only show their support for each other but also their growth as individuals. Also, a story about them planning a big family event, like Pan's birthday, could be really interesting as it would show their family dynamic.
Perhaps a plot where Bulma creates a new invention that goes wrong and accidentally gives Vegeta some strange powers. They then have to figure out how to reverse it while also dealing with their feelings for each other. It could involve some comical situations as Vegeta tries to control these new powers and Bulma tries to help him, all while their love story unfolds.
Well, a story could be set during a time when Bulma is pregnant with their second child. She's having a difficult pregnancy, and Vegeta has to learn to be more supportive and understanding. This could lead to some really sweet and also some tense moments between them. They could also have an adventure together during this time, like trying to find a special herb on a far - off planet that's supposed to help with the pregnancy.
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.
A plot could involve Gohan being accidentally sent to a dimension where everything is made of lemon - scented substances. He has to find a way back home while dealing with the strange inhabitants of this world. He could learn some unique skills from them that are related to the lemon environment, like using lemon - essence to boost his ki attacks in a new way.
One idea could be a story where Gohan and Android 18 team up for a martial arts tournament. The 'lemon' aspect could be used in a light - hearted way, like they share a lemonade after a tough match. Another could be a story where they have to protect a lemon grove from an evil force. Maybe the grove has some special power that the bad guys want.
One idea could be that Trunks discovers a new power while on a mission, and Bulma helps him control it in a unique way. Maybe she creates a device that can enhance his power but also has some unforeseen side effects that lead to some comical and heartwarming moments between them.
One idea could be a training session that takes an unexpected emotional turn. Goku and Gohan are training hard, but then they start sharing their deep feelings for each other as father and son. This could lead to a moment of intense bonding that makes their relationship even stronger.
One idea could be a fanfiction about Bulma and Vegeta going on a space adventure together. They could face new enemies and have to rely on each other's skills to survive. Another idea is a story where they deal with Trunks going through a difficult phase in his teenage years. Maybe he's having trouble with his powers and they have to help him out as parents.
