Yes, there are. Some fanfictions might depict Chi - Chi teaching Gohan important life lessons, like how to balance his human and Saiyan sides. It could also show Gohan looking up to Chi - Chi for her strength and wisdom. They might be involved in heart - warming family moments, such as celebrating holidays or dealing with the challenges that come with being part of the Z - Fighter family.
I haven't come across such a fanfiction myself. It goes against the general nature of their relationship in the original series. Chi - Chi loves Gohan deeply and is very protective of him.
One popular theme is Gohan's growth under Chi - Chi's influence. Chi - Chi has always been strict about Gohan's education, and fanfictions might explore how this affects Gohan's development as a person and a warrior. Another theme could be family unity. Since they are an important part of the Saiyan family in 'Dragon Ball Z', fanfictions could show how they support each other during tough times.
Maybe in a fanfiction where Chi - Chi is mind - controlled by an extremely powerful villain. The villain could manipulate her into doing such a horrible thing against her will.
One reason could be a new, extremely powerful villain who targets Earth and Chi - Chi unfortunately gets in the way. Maybe this villain has a vendetta against Goku and decides to hurt him by killing his wife.
There are many. One type of fanfiction could be about Goku and Chi - Chi's courtship. Maybe it details how Goku finally realized his feelings for Chi - Chi. Another aspect could be their cultural differences, since Goku grew up with a different set of values as a Saiyan. Fanfictions might explore how they overcome these differences in their relationship.
Family is a common theme. Since they have a family in the Dragon Ball series, fanfictions often explore how they raise their kids. Another theme is love, of course, showing the depth of their relationship.
One possible fanfiction idea could be that Gohan's sister discovers she has a unique power that no one else in the family has. Maybe she can communicate with animals in a way that helps the Z - fighters. For example, she could get information from the animals about the whereabouts of the next big threat to Earth.
Sure. Many fanfic writers like to delve into the relationships between characters. Chi Chi and Bulma have a long history in the Dragon Ball universe. A fanfic about their friendship might show how they support each other, deal with the crazy adventures their male counterparts get into, and bond over their own unique strengths and weaknesses. For example, Chi Chi's strong - willed nature and Bulma's intelligence could make for a great combination in a story about their friendship.
One possible fanfiction could be about Bulma helping Gohan with his studies. Since Bulma is super smart, she could tutor Gohan in advanced science and technology. This would not only strengthen their friendship but also give Gohan new knowledge that might come in handy during his battles. For example, understanding the principles of energy and mechanics could help him better strategize against his enemies.
One unique aspect is the exploration of female relationships in the Dragon Ball world. Since most of the focus in the original is on the male fighters, fanfictions about Chi - Chi and Maron give a different perspective. For example, they can show how the two deal with the male - dominated environment.
