From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Cymbal (シンバル, Shinbaru; FUNimation "Cymbal", Viz "Cymbal") is Piccolo Daimao's third son following his release. He is a large, humanoid, Dragon-like Namekian and his mutation is related to his apparent specialty, finding Dragon Balls (Piccolo Daimao mutters that it is only fitting that such a spawn resemble a Dragon).
Cymbal's Japanese name is a pun on the word Shinbaru, or Cymbal in English.
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 (with his wings, like Tambourine) and showed his fighting prowess when he punched Yajirobe and later fired some electricity/ki blasts at him before meeting his end. Excepting Piano, who we never see fight, he is the weakest of King Piccolo's spawns, and his older brother Tambourine is described as being "several times stronger than him."
- Chou Makouhou – As spawns who share strong a resemblance with Cymbal have the ability to shoot a beam of energy from their mouth, therefore it is assumed that Cymbal can do this also.
- Electric Wave – Cymbal uses the Electric Wave (电撃波, Dengekiha) in his fight against Yajirobe.
- Flight – Cymbal can fly using his wings.
- Cymbal is the first Namekian born and hatched on-screen in the series.
- Goku and Yajirobe play rock, paper, scissors for the first time in order to decide who will fight Cymbal. This situation is mirrored many years later when Goku, Gohan, and Vegeta do the same to decide who gets to fight first in Babidi's Spaceship and again when Goku and Vegeta fight Kid Buu, but this time Goku wins.
- Cymbal is the first and only villain to be killed by Yajirobe.
- In the video game, Infinite World, when finding the Dragon Balls in a desert, you can see a skeleton head which resembles Cymbal's remains after Yajirobe had eaten him.
