One possible plot could be that Bardock and Gine somehow travel through time or dimensions to meet Goku on Earth. They could be shocked to see how strong and kind - hearted Goku has become, despite not growing up on Planet Vegeta. Goku, in turn, would be amazed to meet his parents and learn more about his Saiyan heritage from them.
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.
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.
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.
With Gine, her character can be developed by exploring her feelings towards Goku. She could be shown as a loving and proud mother, but also with a sense of sadness for all the years she missed with him. Her interactions with Goku could bring out her more maternal instincts, and she might start to see Goku as a symbol of hope for the Saiyan race.
In this fanfiction scenario, Gine's meeting with Goku and Raditz could be filled with various emotions. Maybe Gine is overjoyed to see Goku, her long - lost son. And when it comes to Raditz, there could be a sense of family reunion despite their past differences. It could be a moment of shock and then warm acceptance as they all come to terms with their relationships.
Well, it could be that Gohan meets them in a strange time - space rift. Bardock and Gine, seeing Gohan, might be initially shocked at his different Saiyan - human hybrid form. Gohan could then tell them about the future, about the battles against the Saiyans' enemies. They might form an unlikely alliance to face some new threat that spans across different timelines.
At first, it might be tense. Bardock is a hardened Saiyan warrior from a different era, and Goku has grown up on Earth with a very different set of values. But as they start to communicate, they would find common ground in their Saiyan blood. Goku's pure - heartedness could gradually win over Bardock, and Bardock's strength and pride could earn Goku's respect.
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 potential storyline could be that Gine saves Goku from a powerful enemy. Since she is his mother, she has a strong instinct to protect him. Another could be that Goku and Gine team up to fight against Frieza or other villains who pose a threat to the universe.
