Sonic the decliver was a successful microwave seller, but one day the market went so quiet that he literally had to leave everything and became bankrupt (hence the nickname decliver), he found a friend who let him live in his house for free. This was until DJ Moman arrived, the DJ conquered people with his DJ music and remixes that began to make people stop going to Sonic's friend's Jaz concerts. Given this, the friend sent Sonic to stop dj moman or yes or what made the house. from there, the legend of sonic the decliner was born
