Pisthacos are legendary creatures from Peruvian folklore that were said to kill travelers on lonely roads in order to extract and sell their fat. According to the legends, Pisthacos appeared in pre-Hispanic times and looked different than Incas with blond hair and blue eyes. While considered a legend for many years, in 2009 four men were arrested in Peru for actually killing people and extracting/selling their fat for cosmetic uses in Europe, lending some credibility to the old folktales.
