The Terrible Trio were a group of criminals representing land, sea and air.
The Trio were originally three rich, powerful and spolied youths in Gotham City, who first became friends in a fraternity catering almost exclusively to the rich. After trying every pursuit normally open to the rich - big-game hunting, treasure hunts, deep sea diving - they were still bored with their lives, and decided to try crime. Each of them adopted aliases that mirrored their families' businesses: Warren Lawford, who inherited an oil fortune, became "The Fox"; Armand Lydecker, whose family owned an aerodynamics firm, "The Vulture"; and Gunther Hardwicke, the son of a shipping magnate, "The Shark." They committed a series of daring heists throughout Gotham, and were thrilled with their success. They were even more thrilled when they managed to escape Batman.
Lawford was romantically involved with Rebecca Fallbrook, daughter of businessman Sheldon Fallbrook, one of the Trio's heist victims. When Rebecca stumbled onto their criminal activities, Lawford was paranoid enough (and emboldened enough by their string of successes) to decide she was a threat and tried to kill her, to the horror of Lydecker and Hardwicke. Batman saved her and apprehended the Trio. Lawford was last seen as his prison cell at Stonegate Penitentiary slammed shut behind him, leaving him terrified out of his wits.
Powers and Abilities
The trio had no extraordinary powers, but all three of them were physically fit, inventive, and audacious. They had the resources to plan their crimes carefully, and to equip themselves with a high-tech arsenal similar to Batman's, including a harpoon gun with a cable for quick escapes, and a car outfitted with a hidden weapons system.
