we know now that majin buu is ancient creature older than old kai.who created him?Though in the manga Kaiōshin said that Bibidi made him, the truth is that one called “Buu” was not actually created by Bididi, but has existed since time immemorial. He cycled between rampages and long hibernation. During numerous iterations of this cycle, he absorbed the evil elements of mankind, becoming steadily more violent.
the gods of creation,kaioshins,are borned from the divine tree.they are naturally gods and naturally strong.
however,the gods of destruction are people who were chosen? and they need a master to be strong? I wonder if there was a "natural" god of destruction at the beginning of the universe.
let's take a look of my hypothetical story of majin buu:
at the beginning of the universe.the god of creation were borned from the divine tree and the god of destruction were borned from the,well, divine mud
the kaioshins were very intelligent to create planets, buu was a pure heart creature with massive destructive power.he destroys planets for a certain time and then the go into long hibernation.He cycled between rampages and long hibernation.
they gave the balance for the universe until something bad happened. buu was corrupted by the wickedness of the intelligent living beings. he became violent and destroyed more than what was necessary.During numerous iterations of this cycle, he absorbed the evil elements of mankind, becoming steadily more violent.
then he went into another hibernation. "the manager" of the universe(whis?) thinks it's a better idea to not use the "natural" god of destruction anymore. he chose and trained someone to play that role.the universe was very well with natural gods of creation and chosen gods of destruction,the manager decide the "old model" is not necessary anymore,so he won't wake it up. buu was going to sleep forever,but...
an evil wizard somehow managed to summon buu,and buu stated was he was born for: destroy.Bibidi merely knew the means of calling Buu from out of his long slumber.
whis decided to not stop buu. since buu was killing the living beings because it's their own wickedness that made buu kill them. it was karma.
well,that is the story.it is, of course,just a hypothesis.
do you think buu is very weak to be a god of destruction? well, beerus was weaker than buu millions years ago. and both of them have to go into a hibernation from time to time.
