Having no musical talent whatsoever, no band would take him as a member. He turned his technical expertise to the creation of sonic weaponry in the form of guitars, intending to prove to the world his musical skills. His guitar is "capable of making force-fields, enabling him to ride on currents of sound and project sound blasts of concussive force."
His main weakness as a villain is his over-reliance on it. Once his guitar is removed from his hands or sufficiently damaged to cease functioning, Trash is rendered helpless.
