The South Supreme Kai lived a peaceful life on the Sacred World of the Kais with the other Supreme Kais. After both the West and North Supreme Kais were killed by Majin Buu, South Supreme Kai was the next Kai to face the creature in combat. He managed to fight evenly with Buu, countering his attacks, landing a headbutt, and managing to rip the monster's arm off, which genuinely hurt and damaged Buu. However, Buu soon gained the advantage, dodging the Kai's energy ball and dealing severe damage to him with just a single kick to the back. South Supreme Kai was ultimately defeated after the creature absorbed him with a sneak attack; the absorption of South Supreme Kai transformed Buu into a large, hulking Majin.
Due to being trapped within Buu over the next several million years, South Supreme Kai is permanently fused within the creature's being, never to be seen again. This also happens to Grand Supreme Kai, who is also permanently fused within Buu and becomes the basis for the creature's innocent form.

The East Supreme Kai states that South Supreme Kai was the strongest of the Supreme Kais ever, strong enough that Buu absorbed him. Additionally, Super Buu gets his tremendous power due to having absorbed the Southern Supreme Kai.
