One common theme is the exploration of their relationship. Since they have very different personalities, it's interesting to see how they interact and grow closer. Another theme is power - how Fem Goku's power, which might be different from the male Goku's in some interpretations, and Vegeta's power combine or contrast.
A frequent theme is the adaptation of their Saiyan heritage in a female context. In many fanfictions, fem Goku and fem Vegeta have to deal with the expectations of being female Saiyans in a way that's different from the male counterparts. Also, there's the theme of self - discovery. They might discover new aspects of their personalities that are related to their new gender identity. It's like they are re - defining what it means to be a Saiyan as a female.
Goku and Fem Vegeta are the main characters. Goku, the ever - evolving Saiyan hero, is always looking for ways to improve himself and protect the Earth. Fem Vegeta, being a female counterpart of the proud Saiyan prince, would bring her own set of characteristics. She might be more in touch with her emotions than the original Vegeta, which could add an interesting dynamic to her relationship with Goku. Their relationship, be it friendly rivalry or something more, would drive the story forward in this fanfiction.
One interesting plotline could be Goku and Fem Vegeta teaming up for a special mission in a new, unknown part of the universe. They might face challenges that force them to rely on each other's unique skills and grow closer as a result.
One popular Vegeta and Fem Goku fanfiction is 'The New Power Duo'. It shows them teaming up against a new, powerful enemy in a creative and exciting way. The story focuses on how their different personalities interact and how they grow to respect each other more as they face challenges together.
There's a fanfiction called 'Fem Goku and Vegeta's New Adventure'. In this story, they team up in a whole new way. The author does a good job of adapting their traditional male characteristics into female ones. For example, fem Goku is still super - strong and has a big appetite, but with a feminine touch. And fem Vegeta is still proud but shows her emotions in a more nuanced way. It's a really engaging read.
Android 18 might be a good addition. She's strong and has a complex personality. Her presence could add a new dynamic to the harem, especially with her ability to stand up to both Goku and Fem Vegeta. And her relationship with Krillin could also be a factor in the story.
One popular fem Goku and Vegeta love fanfiction might be 'A New Bond'. In it, fem Goku and Vegeta start off as rivals but gradually develop a deeper connection. Another could be 'Love in the Saiyan Realm' where their relationship is explored in the context of Saiyan culture. There are also some on fanfiction.net that focus on their unique love story.
Maybe in the fanfiction, Goku and Fem Vegeta start a harem as a way to train stronger fighters. They bring in various characters from different planets and train them in their unique ways. Along the way, romantic feelings start to develop between the members of the harem and Goku and Fem Vegeta have to deal with the resulting jealousies and rivalries.
Yes, in the vast world of fanfiction, there are all kinds of creative and out - of - the - box stories. Some fans like to explore unusual relationships and scenarios, so it's possible that there is such a fanfiction out there. However, it goes against the original canon of the Dragon Ball series in many ways.
