He created Ray and had him plant explosives in certain parts of the sewer so that he can sink the city beneath the ocean. Ray is just one of the first fish-men that Polidorius planned on creating for his underwater city. Ray kidnapped April O'Neil and Polidorius mutated her into a fish-woman in an effort to provide a mate for Ray. The Turtles tracked down Polidorius with the help of April's fish powers. The Turtles made him change her back to a human again while Ray escaped. He is never seen again and is probably sent to a sanitarium.
