Ivan Romanoff was a human who lived in Russia in the 20th century. He was a sergeant in the Russian army during World War II. In 1942, Romanoff met John Kirk during a "wild night in Moscow". Sometime later, Romanoff was one of two Russians who entered a German prison camp in Stalingrad during the great battle in the city. Disguised in German uniforms, they hoped to steal a Ju-52 transport plane which was needed to fly Commissar Nikita Khrushchev to Moscow. The two were caught by the Germans, and in the ensuing struggle Romanoff mistakenly shot the time-lost Pavel Chekov on the helmet, not realizing he was Russian.
