Nikolai was a Russian Ultranationalist in Call of Duty 4: Modern Warfare. He appears in the "The Sins of the Father" mission, as a minor character in the apartment where Victor Zakhaev fled to when being chased by S.A.S, U.S.M.C and Loyalists. Nikolai's existence can be confirmed when entering the five story building. An Ultranationalist calls for Nikolai. He was killed by either John "Soap" MacTavish, Gaz or SSgt. Griggs, then the other Ultranationalists are killed.
