Robot Master

Robot Master is what the robots of the Robot Ranch theme park call their owner, the man who operates their remote controls.

Season one
He who wanted to turn Shaggy Rogers, Scooby-Doo, and Scrappy-Doo into new robots (the dogs into prairie dogs and the man into a new greenhorn character). He sent the robot Rawhide Red after them, and also controlled the robot horses they were riding to buck them off. He was defeated when Scrappy got hold of his remote control, and made Rawhide Red act as a train engine to help them escape.
