In 1993 Hanna-Barbera released an animated series with comic book style visuals and anthropomorphic characters. This program was SWAT Kats: The Radical Squadron, and it was based on characters created by Christian and Yvon Tremblay. Despite early cancellation in its second season, the series was a relative hit with viewers.
Morbulus was one of the villains encountered by the SWAT Kats early in their career as vigilantes. He literally has eyes in the back of his head, giving him 360-degree vision and making him difficult to take by surprise. Morbulus (for reasons never revealed) attempted to destroy all the oil refineries in Megakat City, in a spree dubbed by the media as the "Refinery Reign of Terror."
