He could leave to find a way to prevent future threats like Cell from emerging. Since he's seen the destruction that such a powerful enemy can cause, he might feel responsible for making sure it doesn't happen again. So he'll go on a journey to learn more about the origins of these threats and how to stop them at their source.
Perhaps Gohan will leave to be alone and deal with the emotional trauma of the Cell Games. He had to make some tough decisions during the battle, like sacrificing himself at one point. All that stress and the knowledge of the power he holds could be too much to handle around others. So he'll go off to a secluded place to come to terms with it all.
Well, one possibility is that Gohan might go into a period of self - discovery. After such a huge battle, he's likely to question his role in the world. Maybe he'll travel to find other powerful fighters and train with them. Another thing could be that he'll try to live a normal life for a while, like going back to school, but find it difficult because of his new - found power and the memories of the Cell Games.
One possibility in the 'Gohan Trains After Cell Games' fanfiction is that Gohan is training not just for physical strength but also for mental strength. He has seen the horrors of the Cell Games and realizes that a strong mind is as important as a strong body. So he might be doing meditation - like training, learning to control his emotions better in battle. He could also be training to sense ki more effectively, which would give him an edge in combat against stronger opponents in the future.
Well, in this fanfiction, Gohan and Videl could have a really intense moment. Maybe Gohan shows off his amazing power during the Cell Games in a way that makes Videl fall for him even more. She might be in awe of his strength and determination.
In the fanfiction, Gohan and Videl's meeting at the Cell Games could be a turning point. Gohan's display of his Super Saiyan powers might inspire Videl to train harder. She could see the importance of having such strength to protect the world. And Gohan might start to notice Videl's determination and beauty. Their meeting could set off a chain of events that leads to them becoming closer allies or even more than that in the world of the fanfiction.
If Gohan died in the Cell Games in fanfiction, it would be a game-changer. It could trigger new plotlines and character developments. Maybe Vegeta would have a change of heart or new allies would emerge to help the Z Fighters.
The story would likely take a very dark turn. Other characters might step up and try to fill Gohan's role, but it would be a huge challenge. It could also change the outcome of the Cell Games completely.
Well, the story could take a very different turn. Gohan was a symbol of hope for a new generation of fighters. His death would shatter that hope. The remaining Z - Fighters would have to reevaluate their strategies and training methods. Maybe they would start to focus more on group attacks rather than relying on individual powerhouses like Gohan. And the fanfiction could explore how the other characters grow and change in the face of this great loss. They might also seek new allies or ways to resurrect Gohan, which could lead to all kinds of new adventures and challenges.
He could meet an old master from the past who has some unique training methods. This master might teach Gohan some long - forgotten Saiyan techniques.
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.
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.
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.
