The Terrible Trio is a group of supervillains appearing in comic books published by DC Comics, first appearing in Detective Comics #253 (March 1958). Individually known as Fox, Vulture, and Shark, their respective real names were originally Warren Lawford, Armand Lydecker, and Gunther Hardwick - though these have changed over the decades.
 The Terrible Trio first appeared in Detective Comics #253 and were created by Dave Wood and Sheldon Moldoff.
 The Terrible Trio were originally three famous inventors in Gotham City, who sought new challenges by starting a criminal career. As a gimmick, they dress up in business suits while wearing cartoon masks of animals. From this, they become 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.
 A second group of Terrible Trio were a young group of thugs who took on the identities of Batman's old foes. Batman soon realized that one of the members was Lucius Fox's son, Timothy Fox (the Vulture). He and two other friends co-opted the identities of the original Trio and tried to rob guests of Bruce Wayne's penthouse, but they were subdued and captured by Batman.
 In the Doctor Mid-Nite miniseries, the three have moved their operations to Portsmouth instead of Gotham, and have become the industrial leaders Fisk, Shackley, and Volper, heads of the investment firm Praeda Industries (Praeda meaning "spoils" or "booty", and sharing a root with the word "predator"). In this story, the Trio adopt their guises as part of rituals they perform to bring good fortune to their endeavors, calling upon the spirits of earth, air, and water. The trio attempt to cause simultaneous disasters to much of the city and its coast, leaving only the property in the worst sections of the city - which they owned and could then resell to enormous profit. As part of their plan, the Trio also operate as drug lords, selling the Venom-based steroid A39 to create an army of superstrong zombie-like soldiers. When Doctor Cross begins investigating their affairs they attempt to kill him, but succeed only in apparently blinding him (unbeknownst to them, he gains the abilities that would make him Doctor Mid-Nite). Doctor Mid-Nite foils their plans for the city, and the members of the Trio are caught and sentenced to a total of 800 years in prison.
 In Detective Comics #832 (April 2007), the presumed-to-be-deceased Shark is named as Sherman Shackley. In this issue, the Fox's last name is Fisk and the Vulture's last name Volper, though no first names are given for either character. Here, the Shark, in an attempt to reinvent himself after suffering a psychotic breakdown - presumed to be due to substance abuse - that caused him to 'divorce' himself from his role in the Trio, fakes his own death by pulling out his own teeth and putting them in a recently deceased corpse - putting a shark's teeth in his mouth instead - and attempts to murder his partners under the alias of the 'Fourth Man', only to be stopped by Batman who deduced the truth, as nobody else could know that much about the Trio. The Trio wind up in Arkham Asylum, where the Fox and the Vulture switch their allegiance to Warren White — the "Great White Shark" — who informs Shackley that he cannot be the Shark anymore and that he is taking his place.
 In the DC Rebirth reboot, a new Terrible Trio is introduced in Gotham Academy: Second Semester. This Trio are three Academy students who are part of a secret society dedicated to the Academy's ghost Amity Arkham. Their leader is Amanda Lydecker (Fox), the descendant of the Dutch architect Ambroos Lydecker, who designed both the Academy and Arkham Asylum to honor Amity and who signed his work "Vos" (the Dutch word for "fox"). The other two members are Wendy Lawford (Shark) and Reiner Hardwick (Raven, rather than Vulture), who both immediately surrender when challenged by the Detective Club.
 A different version of the Terrible Trio appeared in Marvel Family #21. They are three monsters summoned from the Netherworld by three carnival brothers, after they can not hire the Marvel Family, but steal a book of magic instead. They draw a circle and summon a Satyr, a Hydra, and Argus, planning to exhibit them and placing them in a cage. What they do not realize is that the monsters have to return in 24 hours unless three replacements are sent. The monsters use their strength to break out of the cage and are able to fight their way past the Marvels who have come to investigate the spellbook's robbery, planning to send the brothers instead of themselves. The Marvels are able to defeat them in the second battle, then take them back to the circle. They transform into their civilian forms to meet the brothers, but when returning to the circle, they are bound and gagged by the monsters who plan to send them back to the Netherworld. When lightning comes down to transport them, it instead transforms them into the Marvel Family who send the monsters back. The brothers then reveal they took footage of the fight and can use it to make money.
 Another version of the Terrible Trio appeared in Superman #88. Therein, Lex Luthor, Toyman, and the Prankster formed an alliance against Superman.
 Another version of the Terrible Trio appeared in Aquaman #24. Therein, the Fisherman aligned with the Invisible Un-Thing and Fire-Haired Karla on behalf of the alien race Them that sought to conquer Earth.
 The Terrible Trio appear in Batman: The Brave and the Bold #11.
