Meanwhile, the monster returns to the underground kingdom of Egos and is destroyed for his failure by the Egos' leader Emperor Zebha. Zebha sends his subordinate Prince Igam to hunt down the two teams. He then visits the Egos' prison dungeons where he is holding the good natured Princess Ial, who reveals that the underground people cannot go out in direct sunlight or will die. Igam transforms into the Black Knight and battles the two teams on the surface. Igam then kidnaps Dyna-Pink and locks her up with Ial.
