Anime has many seasons on the character of Goku and the first of those seasons is the Dragon Ball. It is therefore the start of the journey of the character of Goku, that means it’s the starting place for answering how old is Goku. Because it’s the start of the journey and the first season in the series, the author might not have expected the tremendous success it was going to have. Therefore, the plot was quite loose in this season and IMDB listed several factual errors and other mistakes in the Dragon Ball Season online on their website.
This is one reason that finding out how old is Goku in Dragon Ball may have a different answer. Because, at some places, they said something like Goku was 14. While at another place in the same series, they said Goku was 11(although they tried to give a reason to create some sense of the slip).
First, we’ll start by assuming that Goku just turned 11(using the value that they later corrected). Then we will answer the question of how old is Goku in Dragon Ball as he goes through the series. This Dragon Ball series has 9 sagas. First, let’s have a review of the sagas in it and how much time Goku could have spent in each of them. This is estimation and we need to bunch some things together for the sake of easier calculation. We will bunch together and give the encounters that took less than a few days a rough estimate in weeks.
How old is Goku in Emperor Pilaf Saga:
Goku meets some people, and either helps or saves them. Some of them are enemies in the short term, but overall they remain his allies throughout the whole of Dragon Ball (total time taken is roughly 2-3weeks). There’s a big scene with the Emperor Pilaf(an actual enemy) at the end ( a few days in this last encounter). So, Goku is 11 years and roughly three weeks old.
How old is Goku in the 21st World Martial Art Competition Saga:
Goku goes to his house(2-3days) and then to Master Roshi’s Island(1-3days). Goku and Krilin try to fulfill demands of Master Roshi(3-10days). Then they spend a few days training and then eight months training for tournament and other chores(+8months). Competition where Goku’s skills get tested(1-4days). So Goku is 11Y,10M,1D old.
How old is Goku in Red Ribbon Army Saga:
Dragon ball stolen, Emperor Pilaf snatching ball, Red Ribbon Army pursuing, Colonel Silver, the robot and plane encounter, Miss Snow, Muscle Tower and Major and Android 8(total 1-2 week). Goku knows about West City from Bulma but he finds trouble in a park there(total roughly 1week). Goku’s age is near 11, 10, 3(years, months, days) old at the end of Red Ribbon Army Saga.
How old is Goku in General Blue Saga:
Heading to an Island(2-4days), going to Master Roshi(1-3days), Manouver of the submarine(2-3days),General Blue Attack. The hideout and Goku and Blue Fight(2-3 days), going to Master Roshi(2-4days), pursuit of blue(1-3days), character Senbei tries his hand at the radar(1-4days)). Blue waits in ambush(2-3days), another character’s help helps build a new radar(1-2week). At this point in Dragon Ball, Goku is roughly 11,11,3(years, months, days) old. Just one week away from being a 12-year-old. This estimate is, of course, with the original assumption that at the beginning, character of Goku was a full 11(year) old.
