Well, perhaps a plot where Goku has lost his sense of self due to a powerful dark magic and starts to abuse Vegeta physically and mentally. Or it could be that there's a power imbalance in an alternate timeline and Goku, being much stronger, starts to oppress Vegeta. It's also possible that a false rumor spreads that Vegeta is planning to harm Goku's family, which leads Goku to abuse him in retaliation.
One possible plot could be that Goku is under some sort of mind - control and ends up abusing Vegeta. Another could be in a dark, alternate universe where Goku's character has been twisted and he sees Vegeta as a threat to be eliminated rather than a rival. Maybe there could also be a plot where Goku is tricked into believing Vegeta has done something unforgivable and so he takes out his anger on him.
In some possible plots, Goku might be influenced by an evil entity that makes him turn on Vegeta. This could lead to him using his superior power to bully and abuse Vegeta. Another plot could involve a misunderstanding over a power source. Let's say a new power - up is discovered and both think they should have it. Goku, in a moment of greed and aggression, starts to abuse Vegeta to get it. Also, there could be a plot where Goku is jealous of Vegeta's progress in a certain area and this jealousy turns into abuse as his emotions get out of control.
There might be some out there, but such a concept goes against the more common friendly - rival dynamic between them in the original series. It's not a very popular or positive take in the mainstream fan community. However, in the vast world of fanfiction, you might find some that explore this in a creative, non - malicious way, perhaps as a what - if scenario in an alternate universe where their relationship took a different turn.
One interesting plot could be that in an alternate universe, Goku and Female Vegeta team up to face a new and powerful enemy. Their different fighting styles, Goku's carefree yet determined approach and Female Vegeta's proud and tenacious nature, would create an interesting dynamic during battles. They might start off not getting along well due to their pride but gradually learn to respect and rely on each other as the threat becomes greater.
Some people might create it just for shock value. They know that the original relationship between Goku and Chi - Chi is loving, so by creating something so opposite, they can get a reaction from readers.
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.
Many fanfics have a plot where Goku Black challenges Vegeta's place as the second - strongest Saiyan. This leads to a series of battles and power - up moments for both characters. There could also be a plot where Goku Black infiltrates Vegeta's family life, causing chaos and forcing Vegeta to not only protect his family but also prove his worth as a fighter. And sometimes, the plot focuses on the power struggle within the Saiyan race, with Goku Black representing a new and dangerous element to Vegeta's understanding of Saiyan power.
In some fanfiction, perhaps Goku gets cursed by a powerful enemy. This curse makes him lose his human - like intelligence and abilities, and he starts behaving more like an animal. Vegeta, instead of killing him, decides to keep him as a pet. Maybe he wants to study Goku in this state or he just feels some strange sense of responsibility. Another storyline could be that Vegeta discovers a way to control Goku's mind and uses it to make Goku his pet, but as the story progresses, Vegeta starts to feel guilty about it.
One possible plotline could be that it's all a big misunderstanding. Maybe Vegeta is acting in a way that seems like abuse due to some external influence, like a mind - controlling device or a magical spell. And the story could be about Bulma trying to figure out what's wrong with him and how to break the spell.
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.
It's possible that Vegeta would gain a new respect for Goku. By seeing Goku's memories, he gets to understand the full scope of Goku's life, his struggles, and how he overcame them. This could lead Vegeta to view Goku in a different light and perhaps even strengthen their rivalry in a more positive way.
Fanfiction can take many strange turns, but 'chichi abuses goku fanfiction' is not a common or well - received type. The Dragon Ball franchise is mainly about action, friendship and family love. Chi - Chi loves Goku deeply in the original, so any such fanfiction would be a huge deviation from the source material. Maybe in some very extreme and non - canon interpretations, a writer might come up with such a situation, but it's not in line with the general spirit of the series.
