Piccolo is first introduced as the reincarnation of the evil King Piccolo (ピッコロ大魔王, Pikkoro Daimaō, lit.

However, it is later revealed that he is from the race of alien beings called Namekians. Piccolo is usually referred to as male, but as he is Namekian he is technically genderless. After Goku defeats Piccolo, Piccolo decides to team up with Goku and his friends in order to beat newer, more dangerous threats. He also trains Goku's first child, Son Gohan, and they form a strong bond and he even saves Gohan's life by sacrificing himself.

Around the start of the Namek Saga, it's revealed that Piccolo's name means "another world" in the Namekian language.
