Piano

Piano was King Piccolo's first son after his release from the Electric Rice Cooker. He is a very intelligent, pterodactyl-like Namekian, and is the longest living member of King Piccolo's Mutated Namek sons, witnessing his father seemingly kill the young warrior Goku and surviving long enough to see the beginning of the final showdown between his father and Goku.
Unlike King Piccolo's other sons, Piano was not a fighter-class Namekian and can be closer compared to young Dende on Namek with Guru, serving as his father's attendant. Piano throughout his whole appearance, assisted his father with plans and ideas, and let Tambourine and Cymbal fight, until they were killed. Mere moments after his brother Drum's death at the hands of Goku, Piano is caught in the fight between his father and Goku, when Goku punches King Piccolo and is sent flying into Piano, wounding him. After the fight between King Piccolo and Goku ensues, Piano can be seen sinking into the rubble, which apparently kills Piano as he falls underground.
It has never been determined how strong he actually is or if he could fight. However, he does show the ability to fly using ki, like his father.
