Bibidi Character Facts

Bibidi is a character in the Dragon Ball series. He is a stubby wizard responsible for creating the demon Majin Buu millions of years prior to the beginning of Dragon Ball. He, his son, and Majin Buu's names are a pun on the name of an incantation in the 1950 film Cinderella, "Bibbidi-Bobbidi-Boo". 
Bibidi managed to create Majin Buu by chance in his quest to dominate the universe. After Buu destroyed Planet Alpha, Bibidi is almost (recklessly) killed by the monster, causing Bibidi to briefly fend off Kid Buu. This caused Buu to stare at him, which in turn prompted Bibidi to tell Kid Buu meekly that he is his "father". Bibidi then used his creation to eliminate most of the Supreme Kais ruling over the universe at the time, killing the Western Supreme Kai and Northern Supreme Kai, and absorbing the Southern Supreme kai.
It is not until Majin Buu absorbs the Grand Supreme Kai, signaling a personality shift to innocence, that Bibidi is able to take advantage of the monster and he is made to be controlled to a certain extent, serving him cake every night for his cooperation in conquering planets
However, as Buu tends to become disobedient from time to time, Bibidi devises a Sealed Ball that can be used to temporarily trap the monster. Bibidi decides to reward Buu with sweets when he behaves himself and reseal him in the Magic Ball when he becomes disobedient. Bibidi also uses the Ball to control Buu while he is traveling to another world. Bibidi eventually sends Buu inside his Ball to Earth, which is his next target. However, before Bibidi reaches Earth and releases Buu, he is ultimately killed in battle by Eastern Supreme kai.
