One idea could be that Goku discovers Launch's secret love for lemon-flavored treats during a training break. They bond over sharing some lemon candies and it leads to a friendly competition to see who can endure the most sour lemonade. This simple shared interest could strengthen their friendship in the fanfiction.
Goku and Launch could start with a simple encounter involving lemons, like Goku accidentally bumping into Launch while she is carrying a basket of lemons. This could lead to an apology and then an invitation to share some lemonade. From there, their relationship could grow as they find more common interests related to lemons, such as making lemon pies together.
One possible plot could be that Goku and Launch meet in an unexpected place, like a new planet during one of Goku's adventures. They start as strangers but gradually form a bond as they face common enemies together. Launch's dual personality could add an interesting twist, with her sweet side being attracted to Goku's pure heart, and her more aggressive side coming out to protect him when in danger.
You can focus on their adventures. For example, they could team up to find a magical item that has been lost. Along the way, they encounter various friendly creatures and face some challenges that require both Goku's strength and Launch's cleverness to overcome. There's no need for any inappropriate content, just good - hearted, exciting adventures.
There are quite a few. In some fanfictions, they meet in unusual circumstances. Maybe Goku saves Launch from a bad situation, and that sparks the start of their relationship. It's a unique take on the characters as they both have such distinct traits.
To launch lemon fanfiction, first, you need to have a clear concept or story in mind. Then, you can choose a platform like Wattpad or Archive of Our Own. Create an account if required, and then start writing your lemon - themed fanfiction following the platform's guidelines for content creation and submission.
One of the best practices is to ensure your work is original within the context of the fanfiction. Avoid plagiarizing other works. Also, respect the rules of the platform where you plan to launch. For example, some platforms may have restrictions on the level of explicitness in lemon fanfiction. Another good practice is to engage with the fan community before launching. Get a sense of what they like and dislike.
You can try some popular fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide range of Dragon Ball related fanfictions, including ones about Goku and Launch's relationship.
A really interesting plot could be set in an alternate universe where Goku and Launch are arranged to be married for some political reason in the Saiyan or Earthling world. They start off not really liking each other but as they face challenges together, they fall in love. For example, they have to deal with a group that is against their union and in the process, they learn about each other's strengths and weaknesses.
