Goku He is one of the legendary warriors of Universe 7. dragon ball. We saw him from a young age in his training as a martial arts fighter, training with Master Roshi, Master Karin, Kami Sama, Kaio Sama and now with Beerus and Whis.
Since he was little he marked a unmatched style and at first he carried the sacred staff that he used as a weapon to defeat his staunchest rivals.
However, as time went by, he began to dedicate more work to his punches and kicks, to leave behind the use of external devices during a fight.
Although the reality is that this did not seem like the original plan of Akira Toriyama, when he grew Goku into a man.
The Japanese mangaka would have completely changed Kakarot's fighting style if these sketches were approved in the Shueisha magazine editing room.
Sketches by Akira ToriyamIt has been around for some time on the internet and shows that Goku was going to carry Master Roshi's staff.
What would have happened if the Saiyan raised on Earth used this artifact to face Vegeta, Raditz, Nappa or Frieza? We will never know, but we can imagine it by looking at the drawing.
Why wasn't this version of Goku used in Dragon Ball?
No one knows why it was not used in the end. Doing an analysis it could be said that Goku at that time had a long way to go to reach the level ofe Roshi, not in power, but in wisdom and experience in combat.
According to Dragon Ball Z, during the last arc of the series, Goku reaches this level five years after the Z Fighters defeated Majin Buu. In fact, the Saiyan raised on Earth takes Ubu to train him in his village after he appears in the Martial Arts Tournament.
This is where it would make the most sense for Goku to have Roshi's staff, but we already know that the character pursues another style and is not yet ready to dedicate himself to training new warriors, at least not without trying to increase his power at the same time.
