In the Dragon Ball canon Edit
He is the son, and apparently the reincarnation, of King Piccolo, who was killed by Goku. He is also the missing half of Kami, whom in the early Cell Saga he reunited with (via Namekian Fusion). However, he is still not the Nameless Namekian, as it was stated that Piccolo fused with Kami is weaker than the Nameless Namekian. Therefore, Piccolo fused with Kami is a seperate entity from the Nameless Namekian.
