Well, in Dragon Ball Super fanfiction about Caulifla, her relationships are often a big focus. She could be paired with other Saiyans or even characters from different universes. Her feisty personality makes for some really engaging storylines, especially when she's interacting with more laid - back or serious characters. And her drive to become stronger always adds an element of excitement to any fanfic she's in.
One great fanfiction could be about Cabba training Caulifla in a new technique. In this story, Cabba's patient teaching style could help Caulifla master a powerful move that she then uses to save their planet from a new threat. It would show their relationship growing as teacher and student, and also as friends.
Caulifla and Goku's relationship in fanfiction could be really interesting. Maybe in this fanfiction, they start as rivals. Caulifla, with her Saiyan pride, wants to prove she's stronger than Goku. But as they fight more, they begin to understand each other's fighting styles and develop a mutual respect. This could lead to some really cool training sessions where they both learn new techniques from one another.
One great fanfiction idea could be Caulifla exploring new power-ups. She might discover a unique form that combines her Saiyan strength with some new, unexpected energy source. This could lead to her facing off against powerful foes in the Dragon Ball Super universe in a whole new way.
In a fanfiction, Caulifla could form an alliance with some unexpected characters. For instance, she could team up with Frieza's minions who have turned against him. This would create a really interesting dynamic as they work together towards a common goal, like overthrowing a new, even more powerful tyrant in the Dragon Ball Super world.
There could be a fanfiction where Caulifla teams up with Goku and Vegeta to face an even greater threat than the ones in the original series. This would give her a chance to learn from the two Saiyan legends and show her growth as a warrior. It could also explore her relationships with the other Z - fighters.
Their relationship could also be one of friendly rivals. They are both strong Saiyans. Caulifla might constantly challenge Cabba to battles to prove that she is just as good as him or even better. And Cabba would take these challenges seriously, which in turn would make both of them improve their skills and power levels.
It could be an ancient and powerful wizard. This wizard might have his own motives, like using Caulifla's strength for some sort of dark ritual. He could use his magic to make Caulifla submissive so that she can't resist his commands.
One possible plot could be that Caulifla is faced with an extremely powerful opponent. This opponent might have some sort of special power or ability that makes Caulifla realize she has no choice but to be submissive in order to survive or protect others. For example, the opponent could have the power to destroy her entire race if she doesn't comply. Another aspect could be that this submissiveness is a temporary state as she tries to figure out a way to overcome the situation and become stronger.
