The South Supreme Kai is the largest amongst the Kaioshin from Universe 7. He has a tall ginger mohawk and slightly resembles Android 16.
The South Supreme Kai lived a peaceful life on the Sacred World of the Kai with the other Supreme Kais. 10 Million years ago, South Supreme Kai and Grand Supreme Kai confronted the evil wizard Moro after he destroyed the Iragi Star System and brought about the mass extinction of life on 320 planets. However Moro proved too powerful for them forcing Grand Supreme Kai to use up all of his god powers to seal away Moro's magic allowing the planet destroying wizard to be imprisoned by the Galactic Police.
After both 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 Sphere 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.
What remained of the South Supreme Kai died with the destruction of Kid Buu. 
- Manga and Anime
Like the other Supreme Kais, South Supreme Kai was strong enough to defeat Frieza (before his resurrection) in one blow. In Age 774, Shin states that South Supreme Kai was the strongest of all the Kais ever. Shin also noted that Kid Buu "somehow" absorbed South, suggesting Shin finds it hard to believe he managed to accomplish this feat.
10,000,000 years before Dragon Ball Super, South Supreme Kai proved able to fight the young Moro alongside the Grand Supreme Kai, with the two winning when Grand Supreme Kai sealed Moro's magic away.
It should be noted, that when Buu absorbed him, his power was greater than that of Super Buu. As Goku stated when they removed all of his absorption, he grew stronger rather than weaker. Shin recognized this form of Buu as being the one where he absorbed South, indicating he was incredibly strong.
In a filler scene in the anime, the South Supreme Kai is shown fighting somewhat evenly with Kid Buu (in contrast to the other Supreme Kais who were defeated and killed by Buu with little to no effort).
Despite his strength, it is implied in the anime that he is not as fast as West Supreme Kai as she was able to out run him while carrying the large rice ball that South Supreme Kai was going to have for lunch.
