Dr. Robert Scorpio was a villain that appeared in the cartoon series "Mighty Max".
Dr. Robert Scorpio entered an underground bomb shelter during the late 1960's, intent on surviving the "inevitable" nuclear holocaust of the time. Instead, due to the location of his bomb shelter - former nuclear testing grounds in the Nevada desert - Scorpio gradually became resistant and even dependent on radiation. Unable to leave his irradiated environment after forty years, Scorpio decided he would just irradiate the whole world with the aid of four giant scorpions.
However Scorpio's plan was foiled when Max and the crew arrived to investigate strange radiation in the desert outside of Las Vegas.
