One good storyline could be Bardock and Gine's early days together. Maybe how they first met and fell in love. It could show their adventures as young Saiyans before the destruction of Planet Vegeta.
One great Bardock in Dragon Ball Z fanfiction is often depicted as a fearless and noble Saiyan. He is shown as a warrior who, despite the cruel nature of the Saiyan race at that time, had a sense of honor. In some fanfictions, he manages to break free from the control of Frieza in more creative ways than in the original story, making his character even more complex and interesting.
Frieza is an obvious choice. He is the main villain associated with the destruction of Planet Vegeta. Having him in the fanfiction would create a lot of tension. Bardock and Gine could be on a mission to take revenge on Frieza, which would make for a very exciting and action - packed story.
In this fanfiction scenario, Goku meeting Gine could be really interesting. Gine is Goku's mother, and in a fan - made story, their meeting might involve Gine finally seeing how strong her son has become. Maybe she'd be proud of all his achievements in protecting the Earth and the universe. It could also be a very emotional encounter as Goku has grown up without her presence for most of his life.
A popular version of Bardock in fanfiction is the one who has a premonition of the destruction of the Saiyans much earlier. This Bardock then tries to take actions to prevent it, like gathering other Saiyans who might be sympathetic to his cause. It makes him a hero figure right from the start, rather than just a victim of Frieza's wrath as in the original story.
A fanfiction might explore the idea of Bardock seeing Goku's life through a time - space rift. He witnesses all of Goku's battles and the friends he makes. Bardock is filled with pride but also realizes that Goku has a different path than the traditional Saiyan way. This makes him question the Saiyan culture he once knew. Meanwhile, Goku starts to have strange dreams about his father, which leads him to search for more about his Saiyan heritage.
One great 'Dragon Ball Z Gine and Goku Fanfiction' is 'Gine's Return'. It explores what would happen if Gine came back into Goku's life. It has some really interesting character interactions and a great plot that stays true to the spirit of Dragon Ball Z.
In many Dragon Ball Z fanfictions, Gine is often portrayed as a strong and caring mother figure. She might be shown having hidden powers or a deep knowledge of Saiyan lore that she passes on to her son, Goku. Some fanfictions also explore her relationship with Bardock in more detail, adding emotional depth to their connection.
It could change it a great deal. Goku might learn more about his Saiyan roots earlier, which could potentially make him more in tune with his Saiyan side. This could lead to him training differently or having different goals. For example, he might be more interested in exploring his Saiyan heritage and what it means for his power - up potential.
Some ideas for Dragon Ball Z Gine fanfiction include a time - travel story. Gine could be brought to the present day by some time - traveling villain or device. Then she has to adapt to the new world while also using her Saiyan knowledge and skills to help the Z - fighters. Another idea is to focus on Gine's family. Write about her relationship with Bardock in more depth, or create a story about her extended family on Planet Vegeta that we haven't seen before. You could also do a story where Gine meets the other Saiyans who were resurrected, like Nappa and Raditz, and how she interacts with them.
