The remains of two of the largest predatory mammals of North America are discovered in a cave in Wyoming. The first is a 750-pound Mega-Lion, and the second is an eleven-foot-tall bear equipped with huge claws and muscles. How could an ecosystem support two predators of such size and raw power? Using evidence collected in the cave and studying the skeletal design of each combatant, experts are able to recreate a blow by blow account of how these two ice aged monsters fought to the death.

Sightings of small human-like figures have coincided with missing persons reports within the Alaska Triangle. Could there be a tribe of vicious, carnivorous gnomes roaming the state's untamed interior? The team follows a trail that could lead them directly into an ice cave, the den of these deadly creatures.

Recent sightings around Alaska match native stories of a vicious Arctic mermaid that attacks unsuspecting people. With only five percent of the world's oceans explored, new marine species are being discovered all the time. Could a sinister mermaid be among the oceans' undocumented creatures? Our expert team searches for answers.

Host Leonard Nimoy travels to the peaks of the Himalayas and the valleys of China to hunt for the fabled creature that many say really exists. Includes a startling video that may have captured the beast on tape for the first time.

The Abominable Snowman is among the most frightening and notorious monsters in history. This ferocious nocturnal creature is said to attack people and slaughter their animals. Witnesses report sightings of a strange, hair-covered beast and claim to have heard blood-curdling screams. Evidence amassed over the last century may point to a startling conclusion: that something real and unknown stalks the desolate mountains of the Far East. Scientists and experts will examine the clues while the MonsterQuest team will undertake their most dangerous expedition to date with an epic ascent onto the snowy peaks where recent evidence of the beast was found.

High in the rugged wilderness of Colorado's Rocky Mountains a large hairy creature is said to be preying on the elk and frightening residents. The stories date back centuries with the earliest settlers describing terrifying encounters with a large beast.

A monstrous beast is spotted in the woods of Alaska, in the same area as countless missing person reports. Those who have survived its attacks describe bear-like claws on a towering, wolf-like beast. Is it a mutant bear, an oversized wolf, or some terrifying hybrid of the two? Fossil records indicate that wolf-bear crossbred animals once existed in this area, and the team investigates if it could be a surviving strain or a new one that may be terrorizing the Alaska Triangle.
