Gorgo #20

After Gorgo attacks a Soviet base, the Soviets are able to subdue him and build a robot duplicate of him. The plan is to send the robot Gorgo to accompany cosmonauts to the moon. After the rockets land, the Soviets are attacked by aliens. They unleash the robot Gorgo but it's knocked out of commission by the alien's weapons. The real Gorgo then emerges from a second rocket and decimates the aliens causing them to flee. Around this time, an American rocket lands on the moon. They and the Soviets return to Earth with Gorgo, while the captain stays behind in hopes of making peace with the aliens.
