Ro-Man (Ro-Man Extension XJ-9): It is the evil alien robot from the film Robot Monster. Ro-Man's job is to prepare the earth for an alien invasion. He must observe those who survived the alien death ray. Fortunately for the human survivors, they have an attractive woman among their number. Also lucky for them, the alien robot, who looks like a gorilla in an antennaed diver's helmet, easily falls for the lovely earth women. The aliens are thwarted or was is just a dream?
