Love and friendship are common themes. Since they are two characters, the development of their relationship, whether it's platonic or romantic, can be a central theme. It can show how they support each other through difficult times.
There could be a fanfic where Bardock and Gine team up with other Saiyans to fight a common enemy. This fanfic could focus on their relationship during the battle, how they support each other and use their unique skills. For example, Bardock's combat skills and Gine's more nurturing side coming together to inspire the other Saiyans.
One great 'Bardock x Gine fanfic' could be 'The Unlikely Bond'. It beautifully weaves a story of how Bardock and Gine's relationship might have developed. Another one is 'Destiny's Meeting' which focuses on their first encounter and how it sets the stage for their relationship in a really interesting way. There's also 'Love Across Galaxies' which is more of an epic take on their relationship, showing how their love endures through various challenges across different parts of the universe.
One common theme is forbidden love. Since Saiyan society has its own rules and hierarchies, their relationship might be seen as going against the norm. Another theme is the power of love in a harsh world. Saiyans are known for their strength and battle - oriented nature, but these fanfics often show how love between Bardock and Gine can be a powerful force even in such a world. Also, there's the theme of sacrifice, like one of them might have to sacrifice something for the sake of their relationship or for the other's well - being.
One possibility could be that it focuses on their first encounter. Maybe Bardock saves Gine from some sort of danger on their planet. This could be the start of a deep friendship or even a romantic relationship in the fanfic.
Well, one possibility is that they could be on a mission to save Earth from some unknown threat. Maybe they discover a new form of evil that the Z - fighters on Earth are not yet aware of, and they use their Saiyan powers to fight it off.
In this fanfiction, Goku might finally learn more about his Saiyan heritage from his parents. He could have heart - warming family moments with Gine and Bardock that were never possible in the original story.
One potential plot twist could be that Gine reveals that Goku has a special power that was hidden even from the Saiyan elites. This could completely change how Goku views himself and his capabilities.
They would most likely meet Goku. Since Goku is an important figure on Earth and has Saiyan heritage himself. It would be interesting to see how Bardock and Gine interact with their son who was raised on Earth.
