Gohan

Father:  Goku
Born:  Earth
Race:  Saiyan
          Gohan's mother was very strict on Gohan.  She always had him do his school work and not much play.  She wanted a scholar in the family but due to a training by Piccolo that changes Gohan's mind about the whole thing.  Chi Chi also found it hard to have a scholar in the family when your father is Goku.  Gohan likes to fight and be with Piccolo and Goku's friends.  Gohan turns Super Saiyan 2 during the Cell Saga and defeats Cell with a Kamehameha.  He was born inbetween Dragonball and Dragonball Z. 
          Gohan fought in every saga there was after Dragonball.  He fought in the Raditz Saga, Vegeta Saga, Freeza Saga, Cell Game, Buu Saga, Super #17 Saga, against the Cyborgs, and i think the evil Shenlongs.
