Depicted in Norse poems, berserkers were considered to be fearless warriors capable of supernatural strength and legendary fighting frenzies. While they were seen as merely embellished stories for many years, scientists have recently discovered they were real and their enormous powers were due to intoxicating drugs taken before battle. These made them strong, fearless and numb to pain. Some of these ancient creatures are certainly frightening, although part of us probably still wants to see them in action. Which of them do you hope to have gotten the chance to see in real life? Do you know of any other mythical creature that may have actually existed and would belong on this list?
