Cymbal is King Piccolo's third son following his release. He is a large, humanoid, dragon-like Namekian, and his mutation may be related to his apparent specialty, finding Dragon Balls.
After hatching, Cymbal's first assignment was to gather the remaining Dragon Balls so his father could wish for restored youth and power. After learning of the location of the nearest Dragon Ball from Emperor Pilaf, Cymbal went out to retrieve it. He finds Goku and Yajirobe and demands they hand over the Dragon Ball. When Yajirobe refuses to give it to him, Cymbal threatens to kill him for it. Goku and Yajirobe play rock, paper, scissors to see who fights him. He is killed by Yajirobe, being sliced in half by his katana, roasted and then eaten. Like all of King Piccolo's sons, Cymbal is sent to Hell after his death and he is never seen again. Although short-lived, he showed he could fly and showed his fighting prowess when he punched Yajirobe and later fired some electricity/ki blasts at him before meeting his end.
Like his father and brothers, Cymbal's name is originally a pun on a musical instrument.
