Earth Disappears!! The Original Buu's Single Cruel Blast!!

When Super Buu regressed to a childlike version of himself after his benign counterpart was completely separated from him, Kaibito reveals to Old Kai that the being is Majin Buu's original form. Kaibito explains how, as East Supreme Kai Shin, he was part of a group of four Supreme Kais, who each oversaw a quadrant of the universe and served under the Grand Supreme Kai Dai Kaio. When Original Majin Buu was created by Bibidi, the original sorcerer and Babidi's father, he was much more powerful and dangerous than his later incarnations, and he led Original Buu to kill the North and West Supreme Kais. Kid Buu absorbed the South Supreme Kai and assumed a Hulking Majin Buu. Hulking Buu later absorbed Dai Kaio, which suppressed Original Buu's focus and destructive impulses. As a result, Hulking Buu became the fat and happy Majin Buu that the group first encountered. Back on Earth, Kid Buu creates a powerful ball of energy and throws it at the Earth intent on destroying it. Goku and Vegeta deflect it. In retaliation, Kid Buu creates a ball of energy ten times more powerful than the previous one, and he throws it at the Earth. Knowing that they currently do not have enough strength left to stop it, Goku and Vegeta try to grab everyone and teleport away. Goku and Vegeta are only able to grab Dende, Mr. Satan, and Bee. As the Earth is about to be destroyed, Kaibito appears and instantly transmits Goku, Vegeta, Dende, Mr. Satan, and Bee to the Sacred World of the Kais. Vegeta angrily berates Goku for his failure to save Gohan, Goten, Trunks, and Piccolo.
