Engrained in the history and mythology of India are tales of a ferocious creature, half-man, half-ape. It has been dubbed the monkey-man, and headlines across the world have told of the vicious nocturnal attacks that occurred in India's capital, New Delhi. The city's population was gripped with fear of a violent creature described by eyewitnesses as having sharp claws, fangs, and dark hair. After three people died and dozens were hospitalized fleeing the creature, 3,000 police officers were tasked with capturing the animal, but came up empty handed. Experts were divided over whether this was a case of mass panic or an unknown primate. Even today, witnesses in other parts of the country continue to report terrifying encounters with a similar beast.

Native Americans have long revered huge birds called Thunderbirds. There was a rash of giant bird sightings in Illinois, Texas, and Alaska back in the 1970's. A giant bird with a 15-foot wingspan allegedly attacked a small child in Illinois. Could there really be a giant bird, or is it mass hysteria? Take a scientific journey, and follow the many eyewitnesses' accounts across the country, and examine the most compelling evidence. One-part history, one-part science, and one part monster, discover the truth behind legendary monsters.

Something mysterious and violent is killing the cattle of the North American plains, but what is behind these gruesome attacks: satanic cults, an unknown predator, or something previously unknown to man?

In 1995, a beast dubbed "El Chupacabra," spanish for "The Goatsucker," was first sighted and accused of killing and draining the blood of hundreds of farm animals in Puerto Rico. Eyewitnesses describe it as a two-legged reptile-like beast with sharp claws and sharper fangs. But another rash of sightings, and killings, in Texas more recently produced eyewitness descriptions of a creature that looked very different. This episode will go on the hunt for the Texas chupacabra. And for first time on television, DNA tests will be performed on evidence from both the Puerto Rico and Texas sightings in an effort to scientifically prove just what these mystery beasts could be.

For over 250 years, a frightening winged beast has been menacing the residents of New Jersey. The Jersey Devil is described as a winged half-bird half-horse, with hoofed feet, a reptilian tail, and a penetrating scream.

In 1967, a giant winged monster reportedly terrorized the skies over a small town in West Virginia, ending in a tragic bridge collapse that claimed forty-six lives.

Dogs are known as man's best friend, but now canines are striking fear into many who report attacks by predatory packs. Originally descended from wolves, domesticated dogs were brought to the United States 12,000 years ago and used as aggressive protectors. Today, more and more dogs are being turned loose on the streets and returning to their wild roots. These feral dogs are attacking people. Now, MonsterQuest launches a search to follow these ferals, using state of the art cameras to uncover where they live and how dangerous they are to man.

There have been stories for centuries about huge, aggressive albino sperm whales. They were immortalized by the classic novel "Moby Dick." These stories told of whales targeting ships and ramming them with their huge heads. Could stories like this be true? MonsterQuest heads to the world's oceans to investigate whether there is any truth to the theory that these white whales have become more aggressive.
