Son Gohan

Son 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 lacked 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.

Character description
Gohan, being only half-Saiyan, is unusual in his values and personality. These unique values and personality separate him from pure Saiyans; as powerful as he is, he does not like fighting much. However, when he is forced to fight, he shows special interest in protecting his family and friends. Like his father, Goku, Gohan has a pure and gentle heart. Besides concerning himself with his family (and his studies), Gohan has a strong attachment with his mentor: his father's former archrival named Piccolo. Piccolo was forced to train Gohan after the death of Goku, in the begining of the Dragon Ball Z series. At first, the relationship with Piccolo is a frightening one, but after just one year, Piccolo admits his change because of the friendship he develops with Gohan and even sacrifices himself to save the boy. Because of this, Piccolo can be considered as a surrogate father for Gohan. Krillin also has influence on Gohan, as almost an uncle/nephew relationship, mainly because Krillin is Goku's closest friend. In some cases, Gohan displays a ferocious appetite just like Goku, a trait he presumably inherited from his father.

like goku and the other Saiyans gohan was able to reach the Super Saiyan form during his training in the hyper bolic tyme chamber with his father, ever since then he was never the same, he was more experianced at fighting and has more power hidden among him
