Babidi

Babidi (バビディ) is a character in the Dragon Ball franchise. He makes his debut in "Energy Drain", the 219th episode of Dragon Ball Z, which premiered on March 2, 1994. He makes his first manga appearance in "The Stolen Energy", the 444th chapter of Dragon Ball manga, issued on April 4, 1994. He, his father Bibidi, and Majin Buu's names are a pun on the name of an incantation in the 1950 film Cinderella, "Bibbidi-Bobbidi-Boo."
Babidi is the son of the powerful wizard Bibidi. He is first seen in Dragon Ball Z when he travels to Earth with his minions in order to gather enough energy to revive his father's monstrous creation, Majin Buu. Babidi sends two fighters under his spell, Yamu and Spopovich, to the 25th World Martial Arts Tournament to steal energy for Majin Buu from the other contestants.
Upon receiving the energy, Babidi no longer sees anymore use for these two minions, and so he decides to murder Yamu and Spopovich. He condones another minion, Pui Pui, to shoot Yamu as he flees in terror, as Babidi with gleeful sadism tortures Spopovich to death by slowly expanding his inner energies, causing him to painfully swell like a balloon until he explodes. This sickening behavior defines Babidi's character: a sadistic and insecure man who compensates his shortcomings by torturing and abusing beings more helpless than he. He later regrets doing this action hastily when he realizes that the energy supplied to him by Yamu and Spopovich (coming from Super Saiyan 2 Gohan) filled half of the necessary power to bring Majin Buu back to his full potential, and with this energy Babidi was half way to the point where Majin Buu would be released from his caccoon.
