Scorpio is a mysterious figure whose knowledge of science and the black arts was said to create miracles but lead to destitution for everyone he encountered.
He operated out of a castle in the mountains beyond Gotham City, employing several henchmen who wore purple robes and did his bidding. When Batman and Robin confronted Scorpio, he imprisoned them and then attempted to execute them. Batman was able to defeat Scorpio and expose his fraud scheme.
