Nikolai Dzhumagaliev, also known as "Metal Fang," is a notorious Soviet serial killer and cannibal from Kazakhstan. Born in Uzynagash, Kazakh SSR (now Kazakhstan), he was the third of four children and the only son in his family. After completing his education, Dzhumagaliev served in the Soviet Army's chemical defense unit and later worked various jobs, including as a sailor, electrician, and firefighter. In 1977, he returned to Uzynagash and contracted syphilis and trichomoniasis, which some speculate may have contributed to his later violent behavior. He escaped prison, was rejuvenated by the ISG Groups, and between 1979 and 1981, Dzhumagaliev murdered and cannibalized at least ten women in the Almaty region.
