Doctor Donut

Doctor Donut is a robotics engineer who once won the trust of the Metropia Police Department by donating a SWAT team of robotic soda cans, which were designed with the help of the Bacon Bros, and were quickly accepted in the aftermath of the Captain Cola crisis. These robots turned out to be part of Doctor Donut's scheme to take control of Metropia, which was foiled by Super Root Beer Man.
