Another aspect is how their relationship is depicted in different universes or alternate storylines. Sometimes, they might face challenges that they didn't in the original series. Like, in a fanfic where Goku has to balance his Saiyan warrior side with being a good husband and father in a more modern - day setting. This can lead to some really creative and engaging storylines.
The family they build together is also a positive aspect shown in fanfics. Their son Gohan and later Goten are a big part of their story. The way Goku and Chichi raise their children, with Goku's strength and Chichi's wisdom, is a common theme. Fanfics that focus on this family aspect often show a warm and loving family environment, which is really appealing.
One positive aspect is loyalty. Chichi has always been loyal to Goku, waiting for him during his long absences. And Goku, in his own way, is loyal to the family he has with Chichi. Another aspect is the family they've built together. They have children, and they both play important roles in raising them, which shows their commitment to each other and the family unit.
One interesting aspect could be the exploration of different relationships. Chichi clones interacting with Goku might lead to new storylines. Maybe it shows how Goku would react to multiple versions of Chichi, which could range from confusion to a new kind of understanding of his relationship with her.
There are also fanfics that focus on Chichi's efforts to keep the family together when Goku is away for long periods due to battles or training. It shows her strength as a mother and a wife, and how she manages the household and raises the kids on her own at times.
One positive aspect is their family life. They have a son, Gohan, and their interactions as parents can be explored. For example, how they support Gohan's growth, both in terms of his strength and his character development.
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.
One possible plotline could be Goku's reaction to Chichi being pregnant. Maybe he's initially clueless about how to handle it and has to learn about taking care of a pregnant wife. Another could be Chichi preparing for the baby's arrival while Goku is off training but trying to be more present for her.
One interesting Goku and Chichi love fanfiction could be the one where they go on a journey to find a magical herb to save their family. In this story, their love is tested as they face various challenges and enemies along the way.
One interesting Goku and Chichi love fanfiction could be about their early days of courtship. Maybe it focuses on how Goku, being so naive about relationships at first, slowly realizes his feelings for Chichi. Another could be a story where they face a big challenge in their marriage that tests their love. There are also fanfictions that explore what their relationship would be like if they had more time alone without all the Saiyan battles and threats.
