omg, all of wewe are way off. the characters do have ages. have wewe even heard of the Daizenshuu??? heres a orodha of character ages at the time of raditz,
OMGF IDIOT.Piccolo.Jr was 3 Years old when goku meet chi chi as TEENAGERS.IF wewe dun, waliopelekwa KNOW WHY Piccolo is so young then go watch the whole DBZ.
I think that the ONLY time they quoted Goku age was in Dragon Ball, when he meets Bulma for the first time. He says he is 13, but later on they explained he was only 11 years old.
Well, seeing as how we are at the end of super, I might as well answer their ages kwa story. We know goku is (or claims to be) 13.5. He spends 6 hours au 6 months in the time chamber, making him 14. After defeating King Piccolo at 15 he leaves to train with Kami like he promised. He then returns to fight in the 23rd World Tournament at 18, beats Piccolo who is 3 then marries Chi Chi. Z picks up 5 years later with goku at 23 and his son gohan aged 5. After being killed kwa Piccolo who is now 8, he stays dead for a mwaka making goku physicly 23 but biologicly 24. Remember to subtract 1 mwaka off gokus age untill his 1 mwaka in the time chamber with gohan. Goku beats vegeta who is 5 years older than goku. Goku recovers from his battle with vegeta and is now 25. He travels to namek beats frieza then spends a mwaka on yardrat. Now 26 goku returns to Earth gets the virus 3 years later when the androids are looking for him so he is now 29, then he trains with gohan for a mwaka in the chamber. Now 30 he faces cell, dies, stays dead for 7 years, is revived. So now hes physicly 30 but biologicly 37. He is 42 during Battle of gods, and 43 during super. At the beggining of GT he is 52 but phisicly 45 due to death. When he is transformed into a kid, he is still 52 but in a 12 to 14 mwaka old body. Lastly at the end of GT, presumed dead but possibly alive, he is 152 but physicly in his 50s gohan is 18 years younger than goku. Piccolo is 15 years younger than goku, and vegeta is 5 years older than goku but in gt is 3 years physicly older due to his time in the chamber
