In a fanfiction, Cabba could be developed by having him lose a fight badly and then go through a period of self - reflection and intense training to come back stronger. This would show his determination and growth. Caulifla could be developed by being put in a situation where she has to rely on her wits rather than just her strength. Maybe she is trapped in a maze - like place and has to use her intelligence to find a way out, which would show a different side of her character.
For Cabba, his character could be developed by showing more of his insecurities. Maybe he doubts his ability to lead his people compared to the great Saiyan warriors he has heard about. Caulifla, on the other hand, could be developed by exploring her softer side. Usually she is all about fighting, but showing her caring for her friends or family in a fanfiction would add depth.
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.
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.
One way to develop both characters is by putting them in a situation where they have to rely on their wits rather than just their strength. For example, they get trapped in a high - tech prison designed by an enemy. They have to figure out how to escape using their intelligence and the limited resources around them. This would force them to grow in ways that they haven't before and show different aspects of their personalities.
One plot idea could be Cabba and Caulifla teaming up to face a new, powerful enemy from another universe. They could start off not getting along well due to their different fighting styles and personalities, but as the battle progresses, they learn to work together and combine their techniques for a powerful finish.
Training under Goku would expose them to a whole new level of fighting. They would get to spar with Goku and other Z - Fighters. This would not only improve their physical strength but also their combat strategies. They might even develop new techniques inspired by Goku's fighting style. And they could bring back what they've learned to their own Saiyan race to help it grow stronger.
One way to develop their characters is to put them in situations that force them to grow. For example, if they were stranded on a hostile planet. Bardock would have to rely on his wits and not just his strength. Fasha could show her nurturing side, taking care of Bardock when he's injured. This would show different aspects of their personalities and help in their character development.
A plot could be Cabba confessing his feelings to Caulifla. He might be nervous at first, but after a big battle where they protect each other, he finds the courage. This would create a new dynamic in their relationship.
One way is to focus on their shared adventures. For example, when they are on a quest for a new power source or to stop a new threat, they can rely on each other more. Goku can protect Bulma physically, while Bulma can use her intelligence to help Goku strategize. Another way is to explore their past more deeply. Maybe there are some untold stories from when they first met that can strengthen their bond.
They could go through a period of misunderstanding. Maybe Gohan makes a decision about his future that Chichi doesn't initially understand. Through communication and some trials, they grow closer as they learn more about each other's perspectives.
They could also develop their relationship through training. If Vegeta takes a more hands - on approach to training Trunks, not just as a student but as his son, they could bond over the shared experience of pushing their limits. They could learn new techniques together and grow closer as a result.
