Gohan (孫 悟飯, Son Gohan) is the first son of Goku and Chi-Chi, the older brother of Goten, the husband of Videl, and the father of Pan. Gohan is also the first hybrid (half Human, half Saiyan) to appear in the series. He is named after Goku's adoptive Grandpa Gohan. Gohan's name is a homophone for gohan (御飯), the Japanese word for "cooked rice," which also refers to meals in general. In Mandarin, the reading of 悟飯 is homophone for 午飯 (wûfàn), meaning lunch.
Gohan is a shy and studious intellectual, and as a child, he lacks the Saiyan fighting spirit. He must utilize his incredible half-breed Saiyan potential and emotional reserves to protect those he loves, becoming one of the most powerful Z Fighters. As an adult, he abandons his superhero duties and instead uses his mind as a premier scholar of the Dragon World.
Gohan, Goku, Vegeta and Trunks appear right after the heroes meet Doidle and his pals. Vegeta demands to know who the heroes are, Light says that they are heroes and villains from different universes. Goku, Trunks and Gohan believe it, while Vegeta says that is stupid. Dark challenges Vegeta, but Trunks calms Vegeta. They join. Destonator identifies them, revives Frieza & Perfect Cell and gives them unbelievable power.
Gohan in The Final Destination is the one in the Cell games.
