SonGohan- Son of Son Goku and ChiChi, he appears the first time at the age of 4, about the same time that Raditz appears (beginning of the anime series Dragonball Z). Having been given the same name as SonGokuu's "Step-Grandfather", SonGohan can become more powerful than his father (because he is half-saiya-jín half human -->hybrids are stronger). However, ChiChi is always telling him to study, therefore, he never really explores his fighting capabilities or gains the taste for a good fight. Gohan has his first fight training with Piccolo, after Goku's death. During the fight against Raditz, Piccolo decides to train Gohan and sort of allie with Goku against Vejiita and Nappa. Though Piccolo is very harsh with him during the training, Son Gohan and Piccolo become friends, being Piccolo an idol to Gohan (Piccolo finaly got killed by Nappa in an atempt to protect Gohan). This motivates the participation of Gohan in the Quest for the Namekian Dragonballs in a chance to revive Piccolo. Son Gohan is often seen during part of the series using clothes much like those worn by Piccolo.
Gohan becomes the main character after the Cell Saga (during this time Goku is "dead"). He marries Videl (also known as Beederu). This union results in a daughter, Pan.
After Vegeta is defeated by Goku (he has been revived by the Dragon Balls), Gohan decides to join Kuririn and Bulma on their expedition to find the Planet Namek Dragon Balls so they can save those killed (Yamcha, Tenshinhan, Chaozu, Piccolo) by the Saiyajin invasion. There, he fights the Ginyuu Special Combat Team and Freezer.
Back on earth, he fights evil Androids #19 and #20 along with the other warriors. After Goku recovers from his heart ailment, Gohan trains with his father to ward off the evil Cell, who has decided to wipe out the planet unless someone comes to stop him. Goku, realizing he can't beat Cell, banks his hopes on his son, who has the ability to power up enormously with anger. The fight with Cell, one of the more dramatic scenes of the manga, is a test of Gohan's strength, will, and morals. Gohan, despite all his combat experience, is a pacifist deep down. After all, he wants to be a scientist when he grows up. During the fight with final stage Cell, he becomes Supersaiyajin 2.
Later, when he is 16, Gohan begins to attend Orange Star High School in Satan City, leading a dual life of ordinary student and crime fighter "Great Saiyaman." At this juncture, he enters his first tournament, the 25th Tenkaichibudoukai. However, he leaves in the middle of the tournament in order to stop the evil machinations of Babidi, a sorcerer who releases a monster named Buu. Gohan battles Daabura and evil Buu.
Ten years later, in the epilogue of the manga, we learn that Gohan has devoted his life to studying and has become what he has always wanted to be, a scientist. (We don't know what kinda scientist though)
