The Terrible Trio were originally three famous inventors in Gotham City, who sought new challenges by starting a criminal career. As a gimmick, they dressed up in business suits while wearing cartoon masks of animals. From now on, they would be known as the Fox, the Shark and the Vulture. Tapping into their respective areas of expertise, they base their technology on their respective animal themes. The Trio were recurrent foes of Batman and Robin for years, but they have also battled G'nort, and, more recently, the new Doctor Mid-Nite. Now based in Portsmouth instead of Gotham, the Trio have started a new criminal career as industrial leaders Fisk, Shackley, and Volper.
