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.
The power balance in the Dragon Ball world could be altered. Goku not marrying Chichi means no domestic distractions. He could potentially achieve even higher levels of power faster. This could lead to different power struggles in the universe. Enemies might be more afraid of him, or he could be more involved in preventing threats before they even emerge, changing the overall safety and stability of the Dragon Ball universe.
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.
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.
One common theme is family. Given their roles as husband and wife and as parents, a lot of fanfiction explores how they balance family life with the constant threats in the Dragon Ball Z world. For example, stories might show Goku trying to be a better father while still being the planet's defender.
Love and family are common themes. Since Goku and Chichi are husband and wife, many fanfictions explore how they balance their family life with Goku's constant need to fight and protect the universe. It shows how their love endures through all the challenges.
One great piece of fanfiction could be 'Chichi's Training Regimen for Goku'. In it, Chichi decides to take Goku's training into her own hands to make sure he's not just focused on fighting but also on family. It shows a different side of their relationship, with Chichi being more assertive in Goku's life.
One great fanfiction could be where Goku and Chichi go on a special adventure together in a new dimension. In this story, they might face new enemies and have to rely on their love and their individual powers to get through. It would be a story that really explores their relationship in the context of the 'Dragon Ball Super' universe.
In this fanfiction, the story could develop in a way that Goku's decision not to marry Chi - Chi has a ripple effect on the entire Dragon Ball universe. His friends might be shocked and try to persuade him otherwise. But Goku stands his ground. This could lead to new alliances being formed as some characters side with Goku's decision, while others support Chi - Chi. The lack of the Goku - Chi - Chi marriage also means that Gohan's upbringing is different. He may grow up with a stronger sense of independence, seeing his mother as a sole provider, and this could influence his future actions and development as a fighter.
Maybe in this fanfiction, Goku realizes that he and Chi - Chi have very different personalities. Chi - Chi is often more concerned with family and a stable life, while Goku is a free - spirited adventurer. This clash of values could lead him to decide not to marry her. For example, Chi - Chi may want Goku to stay at home and help raise Gohan, but Goku is eager to explore new planets and fight powerful enemies.
At first, Caulifla might be a bit intimidated by Goku's power. But as they train together, she would start to understand his techniques and philosophy of fighting. Goku would also learn from Caulifla's unique approach to battles. Their relationship could evolve into a deep bond where they rely on each other in tough battles. For example, Goku could save Caulifla from a near - death situation, and in return, Caulifla could come up with a creative battle strategy that helps Goku against a difficult opponent.
Another way is that Goku could use the Spirit Bomb. He could gather energy from all living things on Earth and nearby planets. Android 21, being an artificial being, might not be able to withstand the pure energy of the Spirit Bomb. However, she could try to absorb the energy, but if Goku can overload her absorption capabilities, it would be his victory.
