Professor Sharp's colleague Dr. Bruce "Bad Brains" Huxter creates robotic musicians he calls the Bandroids: guitarist Rivet Rick, keyboardist Techno Tex, bassist Metalhand, and drummer Bob. The Bionic Six serve as bodyguards to the Bandroids' charity concert. Scarab kidnaps Rock-1 and the Bandroids, intending to reprogram the band into his unwitting accomplices in his goal for eternal youth.
