The Master of Sound was a man who wore a fez and who was one of the Elemental Masters during the Serpentine Wars and battled against Acronix and Krux. Unlike his descendant Jacob Pevsner, whose exact relationship to him is unknown, he used his voice, as opposed to a musical instrument, to channel the power of sound.
