Goku and Vegeta are the protagonists in Dragon Ball, but in dragon ball plots, Goku and Vegeta are not definitely protagonists, and their children have a lot of scenes in many times. Goku and Vegeta's sons are Goten, Goku, and Tranx, respectively.
In the plot, Goku has not yet grown up, and Goku and Tranx have each had their own brilliance, so who is more outstanding, the children of Goku and Vegeta?
Goku's son Goku's encounter with Goku can be said to be ups and downs, at the beginning Ofi should only be raised as an ordinary child, and Kiki's expectation for Goku is just to go to college like an ordinary child and find a good job.
But because of Goku's bloodline, it was also decided that his life was destined to be extraordinary. Goku participated in the Earth Protection Station and the two Saiyans at a very young age, and in this battle Goku also played a key role, after which Goku followed Kling to the Namco and Frieza Legion to fight a big battle, because of the experience of war since childhood, so Goku's potential development is also very good.
During his training with Goku in the Spirit Time House, Goku succeeded in becoming a Super Saiyan and directly surpassed Goku in strength, becoming the first warrior among them.
In the battle with Saru, Goku completely broke out and suddenly reached Super Saiyan II, successfully defeating Saru and becoming the great hero who protected the earth.
Later, in the Buou chapter, the Old Realm King God helped Goku improve his own strength, making Goku become the strongest single warrior in Dragon Ball Z.
In contrast, at this point in time, Vegeta's son Tranx's performance is average, of course, because Tranx has not yet grown up, but in the future world, Tranks is a protective god, he is the real protagonist.
In another world, Goku died of a heart attack, and Saiyans such as Vegeta Gohan also died in battle with artificial humans, and only Tranx survived, and he was alone to protect humanity under the threat of artificial humans.
In the end, Tranx chose to go to the future world for help, and after a series of battles, he became much stronger, so he returned to his world and defeated the cyborg to save the world. In the plot of Dragon Ball Super, Tranx's strength is even stronger.
Because the arrival of Zamas and Black Goku has plunged the future world into despair, even Goku and Vegeta's contract is difficult to completely end Zamas.
In the end, it was Tranx who gained the approval of the Earth and became stronger than the super powerful Saiyan form to suppress the combination of Zamas and Black Goku, and it can be said that the Tranx of the future world is the patron saint of the earth, the person who has been recognized by the world.
If you have to make a comparison, it is the future world of Tranx is more powerful, he is a strong warrior, willing to give everything he wants to protect his loved ones. The future Tranx is both powerful and lonely, a true warrior.
