Kami

Kami (神様, Kami-sama, lit. "God", "Deity", or "Divine Being") is the former Guardian of the Earth, and the good counterpart of King Piccolo. Throughout a majority of the story, the character known as Kami was a wise Namekian, who alongside Piccolo, was once a single being, who no longer remembered his real name, although it was revealed that he was the son of Katas. He hatched on Namek and, as a child, was launched by Katas into outer space in a Namekian spaceship which requires at least a basic knowledge of the Namekian language to pilot. The Nameless Namekian later learnt of the Guardian of the Earth, and that its role could be passed down, but only to those pure of heart. Thus, the Namekian split himself into being, while simultaneously expelling the darkness within him. The remaining good half became Kami, while the evil expunged became King Piccolo. Kami is also the Namekian that created Earth's Dragon Balls.
