Appearing in an ancient town, the kaiju Gorudaa was served human sacrifices. When the Science Patrol lost one of it's international members, they went to investigate. There, the vampire-like Gorudaa made his presence known! Swooping down and devouring people, the soaring beast fled. How ever, his attacks came once every week, so Hyata was prepared. Suddenly, Ultraman and Gorudaa clashed, and the giant light warrior defeated the flying monster by damaging his wing.
