Typically, female Vegeta fanfic often focuses on exploring Vegeta's softer side. It might also emphasize relationships, like a romantic relationship between Vegeta and a female character. Another characteristic is that it may give a different perspective on Vegeta's power and his place in the Dragon Ball universe.
Well, if they were brothers in a fanfic, it could change how they interact with the other characters. Maybe they'd have a deeper understanding and fewer power struggles between them. Also, their family background and upbringing could be explored in new and interesting ways.
In a fanfic, Naruto might power up by having a spiritual awakening. He could connect with the spirits of past Hokages in a deeper way, gaining their knowledge and some of their power. This could enhance his existing jutsu and give him new abilities. Vegeta could power up if he were to face a near - death experience against Naruto. This could trigger a hidden potential within him, like a new type of Super Saiyan form that has unique abilities. He could also fuse with another Saiyan (if there were another Saiyan available in the fanfic's scenario) to create an even more powerful being.
Another theme is the Saiyan heritage. These fics often delve into what it means to be a Saiyan for both Bra and Vegeta. They might explore how their Saiyan blood affects their actions, relationships, and the way they view the world. For instance, they could show how Bra discovers and embraces her Saiyan side with Vegeta's influence.
A 'bardock vs king vegeta fanfic' could explore the backstories of both characters. Bardock's story as a Saiyan who starts to question the Frieza regime might contrast with King Vegeta's more traditional and perhaps self - serving rule. Their fight could be a symbol of the changing tides within the Saiyan community. It could also introduce new elements to the Dragon Ball lore, like different forms of Saiyan power that are unique to this fictional encounter.
One popular 'Vegeta Sakura' fanfic is 'Sakura's Saiyan Adventure'. It has an interesting plot where Sakura gets involved in the Saiyan world and has some unique interactions with Vegeta.
One challenge is getting the character of Vegeta right. He has a very distinct personality, with his pride and his desire for power. If you don't capture that essence, the story can feel off. For example, if you make him too meek or too friendly too quickly, it doesn't fit his character.
Another one is 'Vegeta in the Harry Potter World'. Here, Vegeta has to adapt to the magical environment. His initial confusion and then his determination to master the magic (in his own way) is really fun to read. The way he interacts with the Hogwarts students and teachers is full of comical and exciting moments.
A prevalent theme is also the discovery of new aspects of Vegeta's personality. Since he's usually seen as a very dominant and proud character, in 'bottom' fanfics, we get to see his hidden vulnerabilities, his capacity for different kinds of love and loyalty, and how he copes with situations that challenge his traditional self - image.
