In some fanfictions, it might be a really strange and unique concept where Goku is depicted as Vegeta's pet. But this is far from the original relationship in the official Dragon Ball story. It's just a creative and often humorous take that some fanfic writers explore.
Bulma could be involved. Since she has a relationship with Vegeta and is friends with Goku, she might try to mediate between them when Goku snaps at Vegeta. She could be the voice of reason, trying to calm both of them down and make them see each other's point of view.
In Dragon Ball Z fanfiction, Goku is like the unwavering positive force. His determination to get stronger and his uncomplicated view of right and wrong are important elements. He's the one who usually initiates the friendly rivalries and the drive to overcome challenges. Vegeta, being the Saiyan prince, brings a sense of royalty and pride. His struggle with his own identity and his relationship with Goku add depth. Fanfictions often use their characters to explore themes like redemption, friendship, and the limits of power. For example, Vegeta's journey towards accepting Goku as an equal is a common theme that shows his growth as a character.
The plot could start with Vegeta's sister being sent on a mission to Earth. Goku, being the protector of Earth, initially sees her as a threat. But as they interact more, they realize they have a lot in common. They start to explore their feelings for each other secretly. However, Vegeta discovers their relationship and is furious. He challenges Goku to a fight, thinking Goku has betrayed him. In the end, Goku and Vegeta's sister have to prove to Vegeta that their love is real and that it won't harm their relationship as comrades.
It could start with mutual respect. Goku respects Female Vegeta's strength, and she respects his. Then, they might have some friendly competitions which gradually lead to a closer connection. For example, they could compete in a tournament and after the fight, instead of being enemies, they start to understand each other better.
It often starts with a shock or surprise at the mpreg situation. Then, they gradually learn to rely on each other more. For example, Vegeta might start to show a more caring side that he usually hides, and Goku might become more responsible. They'll have to communicate more, sharing their fears and hopes about the future with the baby.
Yes, in the vast world of fanfiction, there are all kinds of creative and out - of - the - box stories. Some fans like to explore unusual relationships and scenarios, so it's possible that there is such a fanfiction out there. However, it goes against the original canon of the Dragon Ball series in many ways.
Well, if they were brothers in a fanfic, it could change how they interact with the other characters. Maybe they'd have a deeper understanding and fewer power struggles between them. Also, their family background and upbringing could be explored in new and interesting ways.
It's a bit hard to say for sure. Both Vegeta and Goku have their moments of strength. Goku has some unique powers and techniques that give him an edge at times, but Vegeta is no slouch either and constantly works to catch up and surpass Goku.
