The communist general known as the Red Barbarian had been unsuccessful in obtaining the plans for a Disintegrator weapon under construction at Stark Industries. The Actor appeared, posing as Nikita Khrushchev, throwing the Barbarian off guard, but then revealed himself and offered his aid. The Actor further demonstrated his skill in disguise and impersonation, and the Barbarian sent him to replace Tony Stark himself, to gain the plans.
The Actor traveled to the Unites States, and, disguised as Tony Stark, easily entered Stark Industries. There the actor succeeded in not only obtaining the plans, but in discovering the fact that Stark himself was Iron Man. The Actor decided to keep the identity a secret in case he ever needed an ace in the hole to redeem some blunder. The Actor returned to the USSR and left his agents to terminate the real Tony Stark, who had been sent away on a false meeting. Stark, as Iron Man, overcame the Actor's agents, and forced them to reveal their actions and plans. Iron Man caught up with the Actor by using a rocket to arrive in the USSR minutes before him. Iron Man ambushed his car, and retook the plans for the Disintegrator. Iron Man then traveled to the Red Barbarian's base, posing as the Actor. Iron Man told the Barbarian that the briefcase was booby-trapped and couldn't be opened for another four hours, and then left, returning to the USA. The real Actor returned to the Red Barbarian, hoping his news of Iron Man's real identity would allow him to be forgiven for failing to gain the plans to the weapon. However, the Red Barbarian saw that the Actor didn't have the plans, and when the Actor said he nothing about the time locked brief case, the Red Barbarian refused to believe the Actor and had him shot as a traitor. 
The Actor was later revealed to not have been killed, working, again, under the command of the Red Barbarian as part of the Neo-Soviets, a group of former Soviet agents. The Actor was able to assist in capturing Iron Man (Tony Stark) by impersonating his best friend James "Rhodey" Rhodes only for his ruse to be broken when Stark punched him out in anger at the seeming betrayal.
