In the Dragon Ball series of anime, Son Goku can be said to be the absolute protagonist, but when drawing Dragon Ball Z, the author Akira Toriyama had the idea of giving up Goku and making Goku the new protagonist, but this idea was finally suppressed by the audience, but in the anime, Akira Toriyama's intention to cultivate Goku can be said to be very obvious, and left a foreshadowing in many places.
At the beginning of Dragon Ball Z, Goku already had his own son Sun Goku, at this time, the Saiyans came to Earth, in order to protect the Earth, Goku chose to join forces with Bik, and later when fighting against his brother Ratiz, Sun Wukong tried his best, and finally chose to die with Latiz, Goku died and came to the World King Star, and Goku was taken away by Bik for training.
In the later plot, Goku also played a very key role, in the battle with the Saiyans, although Goku was seriously injured, but this is also the first embodiment of Goku's super high combat talent, and later Goku chose to go to Nammex, in Nammex, Goku got the help of the Nammex Elder and developed his own potential, the author's purpose can be said to be obvious.
Goku's strength has been strengthened, and it can catch up with Goku's strength faster, but frieza is not yet the time to entrust the future to Goku, but this also lays the groundwork for the later strength of Goku, at the end of frieza, the future Tranx came to Earth, and explains that in the future, after Goku's death, Goku succeeded Goku, but Goku also hung up.
When it comes to the Saru chapter, the author Toriyama's idea of cultivating Goku can be said to be the most obvious, in terms of Sun Wukong's ability at that time, it is not impossible to cultivate to super race two, but the author did not let Goku solve Saru, but chose Goku who was still a child, and Goku's father was also on the side to give assists to the enemy, which was difficult to understand.
As the protagonist of an anime, after saiyan chapter died once, Saru chapter actually died again, even the supporting character Vegeta did not have such treatment, in fact, when Saru blew himself up and took Goku away, the author was ready to make Goku the protagonist of the anime, and succeed Goku as a hero to protect the world, but for some special reasons did not execute.
By the time of the Demon Buu Chapter, Goku was no longer the child, but had become a bully, and because of the delay in his cultivation, Goku did not give up his righteous heart and directly became a Super Saiyan Superman who guarded the entire city, and later the appearance of the Demon Buu made Gohan return to the peak, and Gohan was also developed for the second time at this time.
With the help of the old world king god, Goku can be said to have reached the peak of life, the state of the god rice can be said to be the strongest period of Goku, Goku transformed into a super three can only be beaten into a tie, Goku does not need to transform to crush the strength, the author's love for Goku can be said to be the most obvious, and Goku is finally invincible to the demon Buu, and finally absorbed.
But not to say, the author Toriyama Akira really likes the role of Goku, in Dragon Ball Z is also many times to let Gohan play a very important role, if it is not because Goku's popularity is too high, Goku becoming the protagonist is basically a sure thing, but if you really let Goku become the protagonist, I'm afraid we won't adapt to it when we watch it.
In your opinion, if Goku becomes the protagonist, will you continue to watch Dragon Ball?
