Piccolo Daimao "King Piccolo, Piccolo Dai-Ma-Ku"
About
Piccolo Daimao came into being some 300 years before the beginning of Dragon Ball sometime after a powerful Namekian on Earth attempted to assume the position of guardian of Earth, he was neglected of the position due to the evil that occulted within. As a result, the Namekian concentrated and trained to relinquish the evil within; which conspired into producing two separate entities — if one should perish, the other would also. The concentrated evil being known as Piccolo Daimao. At first, the name "Piccolo" was a reference to the wind instrument, but then a revelation by Mr. Popo to Bulma meant it translated to "different world" in Namekian.
It remained unknown if Piccolo Daimao knew he was a Namekian, as he was shown to know the language and some of his powers and techniques are of Namekian origin, even replicating Guru's throne. If Piccolo Daimao knew, this could mean that the evil within Kami originated from being a Namekian warrior.
