The story would be quite different. Goku might have more freedom to pursue his battles without having to worry about Chichi's concerns. It could also affect the relationships with his kids and the way he interacts with the other characters.
Well, it could be that Gine, upon meeting Chi - Chi, realizes how much Goku has grown and changed because of her. They could all have a meal together, and during that time, Chi - Chi could learn more about Goku's Saiyan heritage from Gine. And Gine might see in Chi - Chi the qualities that make her a great partner for Goku.
Perhaps Goku would form a different kind of bond with his friends. Instead of a marital relationship with Chichi, he might develop a closer brother - like relationship with Krillin. They could go on adventures together, not having to worry about family responsibilities. Goku could also focus more on mentoring younger fighters, like Gohan, in a more detached way, as a master rather than a father.
Well, in many fanfictions, their relationship often develops through shared experiences. For example, they might go through tough times together, like dealing with threats to their family or the Earth. These experiences bring them closer and make their kisses more meaningful, as they represent a deeper bond formed through adversity.
The Saiyan race might be affected differently. Gohan might not be born, or if he was, he would be raised in a completely different environment. Without Goku as a father in the traditional sense, Gohan could potentially turn out to be more independent or follow a different path in life, perhaps not even being interested in fighting like his father was.
Love and family are very common themes. Since they are husband and wife and have a son, many fanfictions explore how they deal with family life together.
Miscommunication can also be a reason. If Chichi misunderstands Goku's intentions, like when he brings home a strange new power - up item that she thinks is dangerous for the family, and she scolds him without really listening to his explanation. Goku, who is not used to having to explain himself in detail, might snap in frustration.
The main characters are obviously Goku and Chichi. Goku is the powerful Saiyan warrior known for his love of fighting and his pure heart. Chichi, on the other hand, is a strong - willed woman who has a deep love for Goku and is determined to keep their family together.
Another theme is the growth of their love over time. Their relationship starts from a rather simple attraction in their youth, but as they face various challenges in life, like threats to the Earth and family problems, their love deepens and matures into a more profound and unbreakable bond.
Well, one possible plot could be that Goku is under some sort of mind - control during a fight and accidentally hurts Chichi. Maybe an enemy has found a way to manipulate Goku's actions, and in his trance - like state, he strikes out at Chichi without realizing it.
Another theme is empowerment. A female Goku can represent a different kind of power, and when paired with ChiChi, they can be a force for change in the Dragon Ball world. They might fight against gender - based discrimination within the story or show that female characters can be just as strong or even stronger in battles and decision - making.
