Raditz the Runt is Goku's older and much taller brother and the eldest son of Bardock and Gine. He was one of the four known remaining Saiyans left alive after his home world was destroyed. He originally seeks Goku in order to recruit him to conquer more planets, but then decides to kidnap his nephew Gohan. Raditz is childish and immature (though not as much as Goku; but both are less rash than a typical Saiyan), usually throwing a fit and shouting when he can't get his way.
