Daikaioh (大界王神 Dai Kaiôshin) (also known as Grand Supreme Kai) was the highest of all Supreme Kais and rules over the entire universe. He is only seen in (Eastern) Supreme Kai's flashback. He lived on the world of the Kais in the Other World, along with the four other Supreme Kais. When Majin Buu comes to the Planet, he 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, but is absorbed seconds later. After Daikaioh is absorbed, Buu forms a new form that looked remarkably similar to Daikaioh. This "Fat Buu" will continue to show Daikaioh's spirit within him and later even becomes Mr. Satan's friend.


  • If the Grand Supreme Kai was released from Fat Buu, it would most likely Result in Buff Buu, and then there would be another battle.
