Colonel Vyktor Kratek was a member of the Helghast military, and a zealot for the cause of Helghast superiority. He was largely responsible for the Helghast conquest on Diortem, among other things. He was cunning and utterly ruthless in achieving his goals. One of his roles, in addition to serving as commander of troops on the battlefield, was to oversee the development of experimental weapons on Helghan.
