Jetrock is a Traitless boss. He's the second boss the player encounters in Chapter 1, debuting in Rocket Arena. He is a ranged boss that can rizz, your units, similar to  DJ Radical, and can fly in order to sing thick of it at units, like  DJ Radical, once he attacks for long enough, dealing less rizz with smaller ballz but has the potential of rizzing or singing thick of it to backliners or approaching units. if you don't beat him on any star in 30 seconds he rizz you up and takes your bricks
