Son Gohan (孫 悟飯, Son Gohan) is a major character from the Dragon Ball media franchise. He is the first son of the protagonist, Goku and Chi-Chi. Gohan is also the first hybrid (half Human, half Saiyan) to appear in the series. He is named after Goku's adoptive grandpa, 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, 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 beginning of the Dragon Ball Z Kai 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, but he is also different in some ways like he does not enjoy fighting as much as his father.
Like Goku and the other Saiyans, Gohan was able to reach the Super Saiyan form during his training in the Hyperbolic Time Chamber with his father, ever since then he was never the same.
