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 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.
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.
There are indeed some great Bardock and Gine fanfics out there. You can start by looking on fanfiction platforms like Archive of Our Own. Some fanfics might explore their relationship before Goku was born, perhaps creating unique backstories for their meeting and the early days of their family. Others could be more action - oriented, with Bardock and Gine facing off against various threats together.
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.
Well, Bardock and Gine are two important characters in the Dragon Ball backstory. While we know that they are Goku's parents, the story doesn't really focus on their love story in a romantic, detailed way. We can think that Saiyans probably had a different way of forming relationships compared to humans. Bardock was out there fighting battles, and Gine was likely dealing with the Saiyan society in her own way. It could be that their relationship was based on mutual respect for each other's strength and the need to continue the Saiyan race. But this is all speculation since the official story doesn't give us a clear - cut love story between them.
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.
Goku would likely be extremely excited. He has always had a longing to know more about his Saiyan heritage and his father. Meeting Bardock would be like a dream come true for him. He'd probably ask a million questions about his past and Saiyan culture. Chi - Chi, on the other hand, would be a bit more reserved at first. She'd be polite but also a bit cautious, as she doesn't know what this Saiyan from Goku's past might be like. But as she sees Goku's joy, she'd warm up to Bardock.
By showing Gine as a protective figure in Baby Goku's life. For example, she could save him from a minor danger, like a small wild animal attack. This would make Baby Goku look up to her more and strengthen their relationship.
