Supremacy tracks down Diamond Jack, who has rigged explosives in a skyscraper, threatening mass destruction. Confident in her abilities, she confronts him, overpowering him in a one-sided battle. However, the villain introduces his robotic ally, Heroine Crusher, leading to a fierce hand-to-hand fight. Supremacy starts strong, but her power quickly wanes as fatigue sets in, taking heavy hits, bearhugs, throat lifts, and backbreakers. She suffers two KO’s before being chained to a pillar, helpless and exhausted. Diamond Jack forces her to play a cruel, rigged card game to determine the hostages’ fate, offering no choice where she can save herself. Supremacy ultimately sacrifices her freedom to save the hostages, but Diamond Jack reveals that her weakened state was due to a green rock used to sap her strength. Defeated and at his mercy, Supremacy is left powerless, forced to serve Diamond Jack as his captive, with no escape in sight.
