Kid Buu charges a large pink energy sphere by raising his hand. As electricity begins to surround the sphere, Kid Buu throws the sphere at his opponent, causing an incredible amount of damage.
Kid Buu prepares this technique in Other World on Grand Kai's planet, against Krillin, Yamcha, Pikkon, Olibu, and many Other World Tournament fighters observing the scene. However, Kid Buu notices the higher energy of Goku and Vegeta powering up as Super Saiyans on the Sacred World of the Kais, and instead chooses to fight them, using Instantaneous Movement to teleport onto the planet.
He later uses the attack several times during the battle against Goku and Vegeta on the Sacred World of the Kais.
