Frankenstein Meets the Spacemonster

In this campy sci-fi horror film, a Martians' desperate bid to preserve their species leads them to kidnap women from Puerto Rico to restart their dwindling population. After an atomic war on Mars wipes out all females, Princess Marcuzan and her loyal sidekick Dr. Nadir travel to Earth to round up potential mates for the Martian breeders. Meanwhile, a disfigured astronaut android, dubbed "Frankenstein" due to its grotesque appearance, wreaks havoc in Puerto Rico after crashing on the island, seeking revenge against his creators. This bizarre tale of intergalactic abduction and robot rampage is a true cult classic of 1960s creature features.
