One common theme is redemption. For example, they might face their past mistakes or the consequences of their actions in a more intense way in hell. Another theme is the power struggle. Since hell is often depicted as a place full of powerful and evil entities, Goku and Vegeta have to constantly prove their strength. Also, friendship and rivalry play a part. Their relationship is complex, and in these stories, they might have to rely on each other more than ever while still maintaining their competitive edge.
Survival is a big theme. In the hell stories, they are in an unfamiliar and dangerous environment. They need to figure out how to survive against the various threats in hell. Additionally, self - discovery is common. They might learn new things about their powers or their Saiyan heritage while in hell. And of course, there's the theme of good vs evil. They are usually pitted against the evil forces of hell, representing the good side and trying to either escape or bring some sort of order to the chaos of hell.
There's also a fanfic called 'Hellish Encounter'. Here, Goku and Vegeta end up in hell and are forced to team up with some of their former enemies who are also trapped there. They face off against a powerful demon lord who is trying to take over the entire underworld. It has some great fight scenes and a unique take on the afterlife concept.
Many Goku and Vegeta fanfictions explore the concept of power. How they strive for more power, what they are willing to sacrifice for it, and how they handle having great power. This can lead to some interesting moral and ethical dilemmas within the stories.
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.
Friendship is often a theme. Despite their differences, they could form an unlikely friendship. In many fanfictions, they might start off as rivals but end up as comrades, much like Goku and the male Vegeta in the original story. And of course, adventure is a big part of it too. They go on quests, fight new enemies and explore new worlds.
The theme of growth is quite prevalent. Both characters grow in different ways. Goku may grow in his understanding of Saiyan culture through his relationship with female Vegeta, while she might grow in her ability to let go of some of her extreme pride. Another common theme is the protection of the universe. They often team up to fight threats to the universe, which shows their sense of responsibility and heroism.
Another theme is friendship and rivalry. Just like in the original stories, female Goku and Vegeta often have a complex relationship. They can be friends who support each other in battles against common enemies, but also rivals who constantly try to outdo each other in terms of power and skill. This dynamic creates a lot of interesting storylines.
One common theme is the evolution of their relationship from rivals to something more. They start as two Saiyans constantly trying to outdo each other, but in the fanfiction, they gradually see each other in a new light.
The theme of adventure is also quite common. Writers send Goku and Female Vegeta on various quests or battles against new enemies. These adventures not only test their physical strength but also their bond. They might travel to new planets or dimensions, facing all kinds of challenges that bring out different sides of their characters and further develop their relationship.
One common theme is the battle of wills. Goku Black and Vegeta are both strong - willed characters, and fanfictions often explore how they clash or come to an understanding.
