A plotline could start with Frieza hearing about Broly's power and being jealous. He then devises a plan to ambush Broly. But Broly, being extremely perceptive in his own way, senses Frieza's approach and is ready for the fight. As the fight progresses, Frieza realizes that Broly is much stronger than he expected and has to use all his dirty tricks to try and win. Or perhaps the plotline could involve Broly being captured by Frieza's forces, and then Broly breaks free and goes on a rampage against Frieza and his minions.
One of the main themes is the clash of generations. Goten represents the new generation of Saiyans while Frieza is from an older, more menacing era. This creates an interesting dynamic. Survival is also often a theme, as Goten has to fight to survive against Frieza's brutal attacks. Additionally, the theme of justice can be seen, where Goten is fighting for what he believes is right against Frieza's tyranny.
A possible fanfiction could focus on a group of Saiyans who are trapped in a dimension where they can only watch the Goku vs Frieza fight on repeat. They start to notice small details in the fight that they hadn't before, like the exact moment Goku's power level spikes or how Frieza is trying to adapt his strategy. This newfound knowledge could then be used by them in some way when they eventually break free from that dimension.
Trunks would also be interested. He has his own experiences with fighting powerful foes and would be eager to see how Goku, a great Saiyan warrior, fares against Frieza. Also, the younger Saiyans like Goten might be interested. They've heard stories about Frieza and would be excited to see their father or other Saiyan heroes in action against such a notorious villain.
Well, 'Goten vs Frieza: The Final Confrontation' is a really interesting piece. It shows how Goten uses his unique skills and training to take on Frieza. And then there's 'A New Hope for Goten Against Frieza' where Goten has to overcome some internal doubts as well as Frieza's powerful attacks. You can usually find these by simply searching on the major fan fiction platforms.
Cabba often develops by becoming more confident. In many fanfics, he starts as a relatively inexperienced Saiyan. But as he faces challenges, like fighting strong opponents from Universe 7, he gains more confidence in his abilities. He also develops his leadership skills, especially when he has to lead his Saiyan comrades in battle or in difficult situations.
Frieza might initially be shocked. He's used to being a feared and powerful being, and the idea of having a family is very foreign to him. So he could be in denial at first.
A fanfiction could focus on Cabba teaching Caulifla about his Saiyan heritage from Universe 6. He could share stories of his training and the values he holds dear. This could lead to Caulifla becoming more interested in her own Saiyan roots and the two of them developing a deeper connection through this cultural exchange.
One idea could be a story about Cabba training Caulifla in a new technique. Cabba, being more experienced in some aspects, could show Caulifla the ropes. They could face various challenges during the training, like dealing with unexpected power surges or difficult terrains.
One possible fanfiction could be about Cabba and Caulifla training together in a new way. They might discover a new technique that combines their unique Saiyan abilities. For example, Cabba's more disciplined approach could blend with Caulifla's more instinctive and wild fighting style to create something amazing. Maybe they are facing a powerful new enemy in their universe and have to rely on each other to overcome it.
