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.
I'm not sure about specific fanfictions on this. But you can try searching on fanfiction - related websites like Archive of Our Own or FanFiction.net. They usually have a large collection of fan - made stories about various characters.
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.
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.
I'm not entirely sure specifically what that particular fanfic is about as there could be many interpretations. 'Caulifla' and 'Goku' are characters from the Dragon Ball series. A fanfic might involve some kind of adventure, relationship exploration, or unique power - up scenarios between them. But without reading it, it's hard to say for certain.
It could be Frieza. Frieza might see Goku having a family as a weakness and try to take advantage of the situation to finally defeat Goku once and for all.
One possible plot could be that Goku and Caulifla accidentally get exposed to some strange energy during a battle that causes an unexpected pregnancy. They then have to deal with the shock and figure out how to balance their warrior lives with the upcoming new life.
It could be a story about cultural exchange. Caulifla comes from a different part of the Dragon Ball universe with her own set of values and traditions. Goku, being the open - minded fighter he is, helps her understand his way of life and vice versa. This exchange of ideas could lead to new fighting techniques and a deeper understanding between them.
It could involve an adventure where they team up to fight a new powerful enemy. Maybe they discover a new form of energy together and have to train to master it.
