Gamera vs. Guiron: Gamera, the giant flying turtle, spins into action when two young boys board a spaceship and are hijacked to a strange planet on the other side of the sun. While the boys evade the clutches of two brain-hungry alien beauties, Gamera must deal with a knife-nosed monster named Guiron. Gamera vs. Jiger: The fire-breathing action continues as Gamera battles one of his greatest foes, Jiger, a horned monster reminiscent of the Triceratops. Drawn to the World Expo in Osaka by an ancient statue, the evil reptile injects Gamera with its parasitic offspring to eliminate the super turtle. Gamera vs. Zigra: The shark-like alien Zigra attacks Earth to enslave the human race as food. Aided by spacewoman X-1, Zigra's wicked plan goes swimmingly until the invaders are challenged by Gamera and confounded by two troublemaking kids. Gamera : super monster: The final entry of the Showa Gamera series plays as a highlight reel reviving all of the previous evil monsters. When the alien Zanon tries to conquer Earth with an army of monsters, three superwomen enlist the help of Gamera to foil the invader's plans.
