Being only half-Saiyan, Gohan 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, Gohan has a truly pure and gentle heart, apart of having the typical Saiyan appetite and will eat anything.

(Go for Kyle Herbert's interpretation, but your own spin wouldn't hurt. All up to you.)
