The Grand Supreme Kai (だいかいおうしん Dai Kaiōshin, lit. "Great God of the Kings of the Worlds*), known as Daikaioh in the initial Funimation dub, is the highest of all Supreme Kais and ruled over the entire Universe 7 before the series takes place.

He still exists and acts through Good Buu (じんブウ(ぜん Majin Bū (Zen), lit. "Demon Person Boo (Good)").


Grand Supreme Kai resembles the fat form of Majin Buu that his absorption would eventually create. He has pink skin and the same pointed ears as his other kin, as well as a mohawk similar to Shin's but of a darker bluish color. His outfit consists of the shirt and trousers usually worn by Supreme Kais but without the regal tunic-like garment over the top. He wears an orange knotted cloth around his waist, as well as the same navy and yellow waistcoat and purple cape as Fat Buu. Also like Fat Buu, he has squinty eyes that normally seem closed until excited.




Grand Supreme Kai

10 million years ago, the Grand Supreme Kai battled Moro alongside South Supreme Kai. By giving up most of his godly power, Grand Supreme Kai was able to seal Moro's magic power, and together they were able to defeat and imprison him.

GSK absorption

Majin Buu absorbs Grand Supreme Kai.

Grand Supreme Kai lived on the Sacred World of the Kai along with the four other Supreme Kais. He was very peace-loving and gorged himself with food. When Majin Buu comes to the planet, Grand Supreme Kai managed to save Shin from Buu, he battled Majin Buu but was overwhelmed and absorbed. In the anime, he unleashed a powerful attack of his own that blasted Buu into pieces, however, Grand Supreme Kai gets absorbed seconds later when Buu's floating particles converged on him.

After Grand Supreme Kai was absorbed, Buu takes a form that looks remarkably similar to Grand Supreme Kai. Grand Supreme Kai's presence within Buu pacifies him to a degree.

Grand Supreme Kai manifests through Buu

After Good Buu is carried off by the Galactic Patrol, Merus stuns Goku and Vegeta and boards them onto the ship. When the two Saiyans wake up, they're informed of the threat of Moro and are told of the battle that took place ten million years ago, where Grand Supreme Kai was forced to sacrifice most of his godly power to seal Moro's magic abilities away. Merus goes on, explaining how Moro has begun to regain his power, and that the only way to stop him was to somehow have Grand Supreme Kai stop Moro once again.

After Buu has awoken, the Galactic Patrol have their licensed hypnotist and aroma-therapist bring Grand Supreme Kai's memories to the surface within Buu, causing Buu to recognize Moro.


Grand Supreme Kai vs. Moro

During his battle with Moro, the Grand Supreme Kai completely manifests himself through Good Buu, specifying that he will only be switching places with Buu until Moro is defeated. Along with Goku and Vegeta, they teleport directly to Moro at the edge of New Namek's atmosphere where they all attack him together. Noticing that Moro's real body is in fact in outer space, Grand Supreme Kai heads off to fight him alone as he is the only one capable of breathing in space. Despite putting up a valiant effort, Grand Supreme Kai is outmatched and so plans to seal his magic power once again using the Kai Kai Matoru though is unable to pull off the technique due to Goku having previously killed Kid Buu, destroying Grand Supreme Kai's power at the same time. Before receiving a finishing blow, he is saved by Merus who gives him the opportunity to grab a hold of Moro and teleport him back to New Namek where Goku and Vegeta and re-join the fight.

When Saganbo arrives with the rest of the escaped prisoners to join Moro's side, Grand Supreme Kai battles with Goku and Vegeta against the convicts but due to them being in an empowered state thanks to Moro's magic and Grand Supreme Kai's current injuries, he falls in battle. Under dire circumstances and New Namek's inevitable demise, Goku has no choice but to grab hold of everyone and make a hasty retreat. At some point shortly afterwards, Buu manifests himself back to normal and falls asleep.


Manga and Anime

Next to South Supreme Kai, Grand Supreme Kai was the most powerful Supreme Kai of his time. At the peak of his power, Grand Supreme Kai was able to compete against the dark wizard Moro. However, even with South Supreme Kai's aid, the Supreme Kais still had a noticeable disadvantage. It was not until Grand Supreme Kai sacrificed most of his godly power that he was able to seal away Moro's magic power and subdue him. This significantly weakened his abilities.

Even after this, like the rest of his peers, he is stated to be much stronger than Shin and strong enough to defeat Frieza with a single blow (before his first resurrection). While ultimately absorbed by Huge Buu, in the anime flashback, this was prompted by the Majin after Grand Supreme Kai launched an attack that cut the foe into several pieces, an attack that Shin noted would have surely killed anyone else.

Eons later, it was shown that Grand Supreme Kai's godly power inherited by Good Buu made the good Majin immune to Moro's dark magic. However, once Moro had his magic fully stored, the Grand Supreme Kai was shown to be at a disadvantage due to lacking the full godly power he once had, since almost all of his remaining godly power had been transferred to Kid Buu and because Moro had also become physically stronger than Grand Supreme Kai after regaining his full power.

Good Buu

Good Buu, Grand Supreme Kai's present day incarnation

By being absorbed by Kid Buu, Grand Supreme Kai became the more dominant aspect of Innocent Buu and later Good Buu. Much later, thanks to the Galactic Patrol, Good Buu regained his memories of his time as Grand Supreme Kai and became capable of fully transforming into him. However, while the Grand Supreme Kai's persona exists as part of Good Buu, he does not retain his full godly power.

  • Grand Supreme Kai's Funimation name, Daikaioh, is a mistranslation on Funimation's part. In Japanese, his title is Dai Kaioshin while Dai Kaio is Grand Kai's title. This is rectified in the dub of Dragon Ball Z Kai, where he's referred to as Grand Supreme Kai.
  • In the fourth volume of the Dragon Ball Super manga, there is a gag panel where Gowasu asks Shin why the Grand Supreme Kai didn't tell him about the Potara time limits. Shin suggests he didn't fuse to stop Majin Buu because he probably didn't know.
