The "Dragon Ball" series of anime is a representative work of Japanese manga artist Akira Toriyama, and in this anime, the protagonist Son Goku has made many friends in the process of growing up, and some friends have been his enemies, of which Bik is such a presence.
Bik is an alien from Namco, and when he first came to Earth, Bik lost his memory due to some accidents, forgetting that he was a Namco, and later in order to become a god, he separated the evil thoughts in his body, which was later the Great Demon King of Bik.
At that time, the Big Demon King of Bik was sealed into the electric pot by the strongest human being at that time, the martial artist Wu Taidou used the magic seal wave, but after many years, the seal of Bik was unsealed, and in order to defeat the Bick Great Demon King, Goku drank the super divine water, and finally destroyed the old Bik with a move through the fist.
But before the old Bik died, he left an egg, which can also be said to be a continuation of his life, which also caused the gods of the earth not to die, and later we learned that Bik had the ability to regenerate, and this regenerative ability was also obtained by Saru in Dragon Ball Z.
In the Saru game, Saru chooses to explode himself because he is not against Goku, and Goku chooses to die with him in order to transfer Saru, but what everyone does not expect is that Saru is not dead, because Saru himself has Bick's cells, as long as the flesh of the brain is not damaged, he can be reborn again.
But the question also arises, since Saru can be reborn through the flesh of the head, then why can't old Beak be reborn after being penetrated by Goku, but can only choose to leave an egg and wait for death? In fact, there is still a big difference between Sharu and Bik.
First of all, Saru and Bik are different in one thing, that is, Saru himself is an artificial man, and Bik is a Namiko, according to the characteristics of seventeenth and eighteenth, the artificial human's physical strength is almost unlimited, but Bik is different, in the battle with Goku, he has exhausted almost all of his strength. And the egg that finally spits out is also Bick's last struggle, because he can't continue to fight.
What Bik thought of at this time was to leave a fire seed through his own strength and leave his own children to avenge himself, but Saru was different, Saru's physical strength was abundant, so he didn't have to care about these things at all, and we can see that after Sharu recovered, due to absorbing Goku's power, he directly reached the level of super two. Even Sun Wuyan, who had just transformed, was barely a rival to Sharu.
In addition, This regenerative ability of Bik is very physically draining, and we can see that every time Bik in the anime uses this ability, it is as if he has done a very physically draining thing, so the old Bik who is penetrated by Goku, even if he regenerates his body, his physical strength is not enough to support the next battle.
So in the end, old Bik could only choose to let his child avenge himself, but what he did not expect was that his child would eventually become a partner of the enemy, but after the final reunion of Bik and the god of heaven, was the newborn Bik the god of heaven or the great demon king of Bik? Or maybe it's just a Namiko who forgot his name.
In your opinion, why didn't Bick Sr. regenerate his body?
