Grand Supreme Kai Character Facts

Grand Supreme Kai is the highest of all Supreme Kais and rules over the entire universe before the series takes place.
Grand Supreme Kai lives on the Sacred World of the Kais along with the four other Supreme Kais. He is very peace-loving and gorges himself with food. When Majin Buu comes to the planet, Grand Supreme Kai manages to save the (Eastern) Supreme Kai from Buu's attack and unleashes a powerful attack of his own that literally blasts Buu into pieces. However, Grand Supreme Kai gets absorbed seconds later. After Grand Supreme Kai was absorbed, Buu takes a form that looks remarkably similar to Grand Supreme Kai. This "fat" Buu would continue to show Grand Supreme Kai's spirit within him and later even becomes Mr. Satan's friend. Grand Supreme Kai's presence within Buu pacifies him.
