Character in Show By Rock!!.
He is a famous musician and composer in Sound World. Due to his notoriety, Dagger Morse signed him onto his record label and forced him to write songs for Morse's up and coming stars.
King is often depicted as a pompadour-spouting silhouette, with his only visible features being his mouth and a red towel. From what can be seen of his outfit, he resembles a shorter Elvis Presley.
King possessed the legendary guitar Strawberry Heart (show By Rock!!) in order to coach Cyan into defeating Dark Monsters, as well as defeat Dagger.
