A common theme is the power - up journey. With Caulifla and Kale being Saiyans, many fanfictions focus on how an OC can either help them in their power - up quests or be inspired by them. Another theme is friendship. The OC might form deep bonds with Caulifla and Kale, going through various adventures together and relying on each other.
Romance is also a prevalent theme. The OC could be in a romantic relationship with either Caulifla, Kale, or both in some polyamorous scenarios. It often involves the exploration of different cultures (since the OC could be from a different background) and how they blend in the context of a relationship. There are also stories that focus on training. The OC, Caulifla, and Kale train together to become stronger, facing tough challenges and rivals during their training sessions.
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.
One common theme is friendship. They are all Saiyans (or part - Saiyan in Gohan's case), and the fics often explore how they bond over their shared heritage. Another theme is growth. Gohan can help Kale and Caulifla grow as fighters, and they can also help him in different ways, like making him more confident in his Saiyan side.
One idea could be a story where Cabba helps Caulifla and Kale train for a big tournament. They face various challenges together and Cabba's unique fighting style influences the sisters to develop new techniques. In the end, they all become stronger and their friendship deepens.
Well, a Goku x Caulifla x Kale fanfiction could potentially be about their adventures together in a new setting. Maybe it could involve them teaming up against a powerful enemy and during that time, their relationships grow and develop in interesting ways. However, 'lemon' usually implies some inappropriate or adult - themed content, which is not something I would encourage. So if we focus on a non - inappropriate version, it could be a story full of friendship and mutual growth.
