Perhaps a story where Cabba accidentally travels back in time and meets a younger Vegeta. Cabba tries to teach Vegeta about the future, about how Saiyans can be more than just ruthless warriors. Vegeta is initially skeptical but slowly starts to see Cabba's point of view, leading to a change in his own approach to life and fighting.
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.
Well, Naruto would probably become extremely powerful. Vegeta's training methods are intense and focused on physical and mental toughness. Naruto might learn new combat techniques and gain a different perspective on power. He could also pick up some of Vegeta's Saiyan pride and become more confident in his abilities.
Another aspect could be their family values. Vegeta has a complex relationship with his family, especially with his father and his own son. Cabba also has his own family and community in Universe 6. A fanfiction could show how their different family experiences shape their Saiyan identities. For example, Cabba's community might be more tight - knit, while Vegeta grew up in a more cut - throat Saiyan society. They could share their stories and learn from each other about what it means to be a Saiyan.
Naruto's character would become more disciplined. Vegeta is a strict trainer, so Naruto would have to follow a more rigid routine. This could make him less impulsive.
A common theme is growth. Both cabba and caulifla are often depicted as growing in their power and skills. For example, in many fanfictions, they train hard and reach new levels of Super Saiyan forms.
In 'cabba x caulifla fanfic', a recurring theme could be the exploration of their different personalities. Cabba is often seen as more reserved, while Caulifla is bold. Fanfics might play on these differences, showing how they complement each other. Another theme could be the idea of them being part of a bigger story within the universe they belong to. For example, how their relationship affects the overall balance of power or the future of their respective races.
One interesting Dragon Ball Cabba fanfiction could be about his training journey in a different dimension. It might explore how he adapts to new techniques and powers there.
