Whatever Grindcore is doing, he loves to do it loud. Cybertron was always a pretty noisy place, what with everyone revving their engines, and then the war. People on Earth really know how to make noise fun though. Human heavy metal is way cooler than the shock-pop he listened to in his home city of Vos. It's easy to find him on any construction project — just follow the incredibly loud music. Rock on, buddy. Rock on.
