The King of the planet Heracles, a longtime rival of Altea, asks Daibazaal to let him assist the Galran Empire in fighting Altra and Golion with his son Samson. Sincline immediately tests Samson's fighting skill by sending him into a ring to face a Beastman. When Samson emerges victorious, Sincline challenges him personally. During the duel, Sincline is distracted by the beauty of Samson's sister, Princess Amue, a dead ringer Fala, and finds himself bested by Samson. King Heracles later offers a challenge to Altea, and Golion is dispatched to the planet Heracles, where Sincline and a Beastified Samson lie in wait.
