Kill Audio is a tough midget that was created by Clockwork, the keeper of Sight and Sound. Clockwork created him to be the Void that would control the musical sector within Sight and Sound. Because of this predestined duty, Kill Audio is devoid of musical creativity, but also immortal. He mysteriously went missing shortly after his creation, and not much is known about him from that period. According to Kill Audio, it felt like he was living each day on repeat during that time. After he returned to Clockwork, he learned what his purpose was, and immediately began an adventure with a group of weird comrades to help put music back in line.
