Aliens Castor and Volks were eager to kill humans, but were defeated by Powerwoman, who then hunted them down. The two fled in disgrace, threatening, "Next time we come to this planet, we won't show any mercy!" At that moment, Doctor Libra grants them new power. Powerwoman falls victim to their counterattack, overpowered and knocked unconscious. Lying helpless, she is forced to drink a diuretic and suffers a degrading abdominal assault, filmed as she involuntarily urinates. Now possessing strength surpassing Powerwoman's, the aliens strangle her with chains, forcing her into a humiliating spread-legged faint. With overwhelming power exceeding even Super Powerwoman, the aliens take their revenge on the superheroine! [BAD END]
