I think that if you traveled to the Dragon Ball world and became a Battle 5 ordinary person. To get stronger and be able to reach a level comparable to Goku. Is there any quick way to do that? As far as I'm concerned, in the Dragon Ball world, Seventeen and Eighteen are an example.
Because Seventeen and Eighteen were both an ordinary earthling before. The combat power was also only like 5. However, in the Saru chapter, we see that either of the seventeenth and eighteenth can completely destroy Vegeta's who has just been transformed into a Super Saiyan.
For that kind of strength, it is possible to cross Goku if you grab a chance in Dragon Ball. Therefore, I think that it is possible to transform yourself into an android. That's one way to do it. Why? Let me talk about some personal opinions.
Skinny down, the ability of the Earth Divine Dragon would certainly not be able to turn itself into an existence comparable to a Super Saiyan. At most, they can make themselves immortal or something like that, but they can't enhance one's strength. Therefore, making oneself stronger through the Dragon Balls was impossible.
However, it is possible to make oneself stronger by being transformed into an android. Once one has been transformed, then one has strength comparable to a Super One. Once you have strength comparable to a Super One. Frieza would be nothing to fear.
As long as one does not fear Frieza, then the Dragon Balls of Earth, the Dragon Balls of Namek, can be used for oneself. In this way, one can further enhance one's strength. Because in the Dragon Balls, Goku and the others also reached the Saru chapter before they had the strength to defeat the 17th.
This shows that as long as one is not a pure Bioroid, then one has the potential to further improve oneself. Therefore, one can completely raise one's strength to Super Two on Earth. Subsequently, one would then travel to the planet Namek. Change one's bloodline through the divine dragon.
Although he was an android, he was still an Earthling, and his potential was limited. Unlike Frieza and Goku. All of these people's bloodlines have no upper limit. Hence. One can turn their bloodline into a Saiyan, or the Frieza clan's bloodline can take them to a higher degree. This would capitalize on surpassing Goku.
The above is for reference only.
