Romance is also a big theme. Writers like to explore the relationship between the two characters, from the initial attraction to the development of deeper feelings. It might include cute moments like Goku being a bit clueless about his feelings and Caulifla being more forward.
Adventure is another theme. They could go on adventures together across different universes, facing new enemies and challenges. For example, they might team up to fight a powerful villain that threatens both their universes, and in the process, their relationship grows stronger as they rely on each other.
The theme of power is also prevalent. Their combined power or the pursuit of greater power individually can be a central focus. Some fics might have them training to reach new levels of power, like achieving new Super Saiyan forms, which is very exciting to read about.
A common theme is training. Since Goku is a master of martial arts, many fanfictions focus on him training Caulifla, like in 'Training Days'. It could be about her learning new forms or just improving her basic skills.
One frequent theme is power - up. Given that Goku is known for his various Super Saiyan forms and Caulifla is also a strong Saiyan, fanfictions like to show them achieving new levels of power, either through training or facing a powerful foe. Additionally, the theme of respect is also common. As they witness each other's strength, they gain respect for one another, which is often depicted in these fanfictions.
Often, a common theme is the discovery of new emotions. Goku, who has mainly focused on fighting and protecting, may find himself in uncharted territory when it comes to love with Caulifla. And for Caulifla, she might be intrigued by Goku's unique personality and abilities. There could also be themes related to the challenges they face together, not just from external enemies but also from their own respective communities who may not understand their relationship.
One common theme is growth. Both caulifla and goku are Saiyans, so fanfics often focus on their growth in power, like learning new techniques.
Friendship and mentorship are also common. Goku is often seen as a mentor figure to Caulifla in these fanfics. They form a bond through training and fighting side by side. Another theme could be the exploration of different universes. Given that they are from different universes in the Dragon Ball series, fanfics may play around with the idea of them exploring each other's worlds and cultures.
Perhaps a story where Caulifla and Goku are on a mission together in an unknown planet. They face various challenges and have to rely on each other's strengths. Caulifla might initially be overconfident, but Goku's experience helps her to understand the importance of strategy and teamwork. Along the way, they start to respect each other more deeply.
A common theme is power - up. Since they are both fighters, many fanfictions focus on how they train and achieve new levels of power together.
One common theme is the exploration of their powers. Since Naruto has his ninja abilities and Caulifla is a Saiyan, writers often like to see how they compare or combine their powers. Another theme is cultural exchange, as Naruto comes from a ninja world and Caulifla from a Saiyan society.
A frequent theme is their relationship with other characters in the Dragon Ball Super universe. For example, how they interact with Goku or Vegeta. Some fanfictions also focus on their backstories and how their past experiences shape their present relationship. Also, there are fanfictions that explore the idea of them facing new threats together and relying on each other in battle. This not only shows their strength as individuals but also as a team. In addition, there are stories that deal with their emotional growth, like how they handle jealousy or rivalry among themselves or with other Saiyans.
