Perhaps Gohan sacrifices himself to save the other Z - fighters. He might choose to take on Cell's full - power attack that was meant for all of them, and in the process, he loses his life. In the fanfiction, it could also be that Cell has some sort of hidden power - up that catches Gohan off - guard and leads to his death.
Another scenario could be that Gohan contracts a deadly and incurable disease in the fanfiction world. Despite the efforts of his family and friends, including the use of any available advanced technology or magic, he succumbs to the illness, leaving everyone in mourning.
It could be that a new threat emerges. Maybe another android, stronger than Cell, was observing the fight and decides to take advantage of the chaos after Gohan's death. This new android could become the main antagonist as it poses a greater danger to the remaining fighters.
In this fanfiction, if Gohan dies in the Cell Games, perhaps the story could focus on how the other characters cope with the loss. For example, Chi - Chi could become a more hardened character, vowing revenge on Cell or any other threats. Piccolo might take on a more fatherly role to Goten, trying to train him to be as strong as Gohan was. And the Earth might be in a state of mourning, which could attract new villains who see it as a time of weakness.
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.
In this fanfiction, Gohan and Videl might have an interaction where Videl tries to understand Gohan's Saiyan heritage. Gohan could explain it to her, and this could create a deeper connection between them. They could also have a moment where they work together to find a weakness in Cell. Videl's human perspective might give Gohan an idea that he hadn't thought of before.
One possible scenario could be that Luffy sacrifices himself to save his crew during a major battle against an extremely powerful enemy. He might use all his strength and energy to protect them, and in the end, it's too much for his body to handle.
Perhaps in a fanfiction, Gohan dies protecting his family. He stands against a powerful foe that targets his loved ones. He endures a brutal battle, but in the end, his injuries are too severe. His death shatters his family and friends, and the Z - fighters are left to pick up the pieces and continue the fight without him.
Maybe he gets mad when his friends are in danger. For example, if Videl is threatened by a powerful villain, Gohan's protective nature kicks in and he gets really mad.
One possible scenario could be that Edward sacrifices himself to defeat a powerful and final enemy. He might use up all his alchemy knowledge and power in one last, desperate attempt to save the world, and his body just can't take the strain.
One possible scenario could be that they sacrifice themselves to save the village from an ultimate evil. They might combine their powers in a final, desperate move that exhausts them completely, leading to their deaths.
