Ivan was a male Human KGB agent in the 1960s. In 1968, he was part of a spy ring based in Albuquerque, New Mexico, working for a front company called Orion Marketing. Ivan and his partner were charged with undermining the United States's Project Hercules, an effort to develop an enhanced fusion bomb. Both Ivan and his partner supposedly left the country just prior to the bomb's scheduled test detonation. (TOS - Star Trek: Assignment: Earth comic: "Brighter Than a Thousand Suns")
