He could be very sad and withdrawn. After all, he expected love and support from his mother, not abuse. So he might start to isolate himself from her in the fanfic.
Gohan might try to talk to his mother and figure out what's wrong. He'll probably be patient at first, but if the abuse continues, he may start to stand up for himself and tell her that her behavior is wrong. In the fanfic, this could lead to a big argument between them as Gohan tries to make her understand his point of view.
It could be that she has different expectations for Gohan's future now. After seeing how powerful he is, she might be worried about him being constantly involved in battles and is frustrated, which leads to her abusing him in the fanfic.
In the long run, they might realize that they need to change their behavior. They could start thinking about how to make it up to Chichi. Maybe they'll go and do some nice things for her, like getting her some flowers or cleaning the house really well without being asked. This would show that they've learned their lesson and are trying to be better sons.
The story could progress with a darker tone. There would be a lot of mourning at first. Then, the remaining characters might start to look for ways to prevent future threats more aggressively. For example, Bulma could use her scientific skills to develop new weapons or defenses.
In fanfiction, Gohan could have a secret power that he discovers during the Cell Games. This power could be related to his Saiyan heritage in a new and unexpected way, like being able to tap into an ancient Saiyan ability that no one else knew about. It could completely change the course of the fight against Cell.
In the fanfiction, the students in Gohan's class could have discussions about the characters during the Cell Games. For instance, they might talk about how Gohan has changed from a shy kid to a powerful fighter. This exploration through their conversations can give new insights into the development of the characters. Also, their reactions to the villains like Cell can show how menacing the bad guys really are.
On the other hand, the anger could also lead to a more open and honest relationship in the long run. If Gohan gets mad and finally expresses his feelings, Chi - chi might realize her mistakes. They could then work together to build a better relationship based on mutual understanding. For example, Chi - chi could give Gohan more freedom and respect his choices more.
The other Z - fighters will surely feel his absence. Vegeta, for example, might be frustrated. He was always in competition with Goku and Gohan's power. Now that Gohan has left, he might feel like there's no one worthy to compete against. Piccolo, who has a special bond with Gohan, will be worried. He'll probably go looking for Gohan at some point, fearing that something bad has happened to him.
No. In the original Dragon Ball series, Chichi is a loving mother and Gohan is her son. A fanfic with such a negative and abusive theme goes against the positive family values shown in the original.
The 'chichi protective of gohan fanfic' may also show how Gohan responds to his mother's protection. He could initially be compliant, but as he grows older and more independent, he might start to resist. For example, when he wants to participate in a dangerous mission to save the world, Chi - Chi would oppose it vehemently. This could lead to a rift between them, but ultimately they would reconcile as they both understand each other's motives better.
One idea could be to focus on Gohan's internal struggle during the Cell Games. Maybe he's doubting his abilities even more than shown in the original, and it's through his friends' and family's words of encouragement that he finally finds his resolve.
