Son Goten is the youngest son of Goku and his wife Chi-Chi, making him a Saiyan and Earthling hybrid. Goten is Gohan's younger brother and Trunks' best friend.
Goten is a fun-loving and kind-hearted person like his father. But thanks to his mother's structured upbringing, he tends to show more common sense and proper manners than his father did as a child even in some cases as an adult. While still being forced to study hard like his older brother by their mother, having mellowed out following Goku's death, Chi-Chi allowed Goten to have more freedom to explore his own interests than Gohan did growing up Chi-Chi even took it upon herself to train Goten in the martial arts. This allowed him to develop love for play-fighting and bug catching.
