episode 235
Goku's father: Bardock. Goku's father-in-law: OX King. Goku's brother-in-law: Mr. Satan. Goku's older brother: Raditz. Goku's Wife: Chi-Chi. Goku's son: Gohan. Goku's second son: Goten. Goku's daugther-in-law: Videl: Goku's grand dautgher: Pan. Goku's daugther-in-law: Bulla. (Yes, Bulla is Goku's dautgher-in-law. But that is only showed in the fan-made episodes. I really don't understand it, because Goten is 7 years older than Bulla. When Goten was teenager, Bulla was just a little girl. Goten was 14, and Bulla 7. And in the fan-made episodes were Bulla 16-17 years old when she and Goten were dating. That makes Goten 23-24 years old.) Goku's great great grandson: Goku Junior.
