It all started when Gohan got kidnapped by Radditz. When Goku and Piccolo came to save Gohan, Radditz beat the both of them up. Gohan heard all of it and unleashed such a great power he saved the both of them and Piccolo had the chance to kill Radditz. After that, Piccolo took Gohan under his wing and trained him for a year. In that year Piccolo and Gohan became friends. Gohan became a true warrior, although he is often afraid. Gohan is getting stronger and after the adventures on Namek and the fights with the androids Goku takes him to the HyperbolicTime Chamber to train him. Meanwhile, Gohan's hidden powers have often shown and Goku knows that Gohan is the only one who can beat Cell, but then he must be able to control his hidden powers. In the Hyperbolic Time Chamber became a Super Saiyan and like Goku, he can stay like that for an unlimited time. During the Cell Games Gohan tells Cell about his power to get him to stop playing, but Cell just want to see these forces. If the Cell Juniors fight the Z fighters and Cell kills Android 16 Gohan's hidden powers come loose and he is finallySuper Saiyan 2. He is now the strongest warrior in this level and he defeats the CellJuniors and Cell himself. In the seven years that follow Chi-Chi's dream comes true, her son Gohan became a successful student. Gohan is on the Orange Star High School and only fights sometimes. During this time, he protects the city as the Great Saiyaman and he meets Videl, Mr.Satan's daughter. Some time later, he participates in the 25th World Tournament, where he is sees his father returned from the afterlife (Goku died during the Cell Games), and he met strange figures like Shin and Kibito. During the tournament, the story of Majin Buu was revealed. Together with Goku and Vegeta he fights his way trough Babidi's ship. During his battle with Dabura, Gohan finds out that has weakened in the recent years. Fortunately for him Dabura pulls back. If the fight between Goku and Majin Vegeta begins Gohan and Shin attempt to stop Majin Buu, but they failed. Majin Buu beats Gohan up and everyone thinks he's dead. However, he is trained by Elder Kai on the planet of Kai and he reaches the Mystic level. He returns to earth and beats Majin Buu up, until Majin Buu absorbs Gotenks and Piccolo. If Goku appears to fuse with Gohan, Buu absorbs Gohan. Just after Gohan was freed Earth explodes and Gohan dies. He was revived with the Namek Dragonballs and started a family with Videl. The couple got a daughter named Pan.
