Kyōryū Sentai Zyuranger is the sixteenth instalment in the long-running Super Sentai franchise of superhero programs. It ran from February 21, 1992 to February 12, 1993, with a total of 50 episodes. It was the first Sentai series to be adapted into an instalment of the American Power Rangers series—footage from all 50 episodes was extensively used for the first season of Mighty Morphin Power Rangers.
Five young warriors from an ancient civilization of Dinosaur-evolved Humans are awakened during the present day after 170 million years of suspended animation when their sworn enemy, Bandora the Witch, is inadvertently released from her magical container on Planet Nemesis by two astronauts. The five warriors, the Zyurangers, must summon the power of mechanical-looking deities known as Shugozyu, each modeled after a different prehistoric beast, in order to protect mankind from Bandora’s evil forces. A sixth warrior, Burai the Dragonranger, later becomes involved with the conflict between the Zyurangers and Bandora’s forces.
