When Kami looked to become Earth's next God/Guardian, he must rid himself of all evil. Through a personal battle, Kami splits himself into two beings; one good and the other evil. The evil half becomes Piccolo-Daimoa, a creature who thrives on destruction. Although, sharing Kami's life force, he is unable to kill his own twin without wiping out himself. When Piccolo-Daimoa is defeated by Goku, he coughs up a single egg, passing on his life force and bonds to it. This new life force becomes Piccolo.

He later learns from Gohan and his other companions that life has alot to offer and you can't always be evil you have to enjoy life..Piccolo fought every fight the rest of the Z fighters fought and always succeded and he dies on earth at the end of DBZGT.
