Kyooryuu Sentai Zyuranger

Kyōryū Sentai Zyuranger (恐竜戦隊ジュウレンジャー Kyōryū Sentai Jūrenjā?), translated into English as Dinosaur Squadron Beast Ranger is a Japanese tokusatsu television series and the sixteenth entry in the long-running Super Sentai franchise of superhero programmes. Produced by Toei Company Ltd. and Bandai, it aired on TV Asahi from February 21, 1992 to February 12, 1993, with a total of 50 episodes. It was the first Sentai series to be adapted as an installment of the American Power Rangers series - footage from all 50 episodes were extensively used for the first season of Mighty Morphin Power Rangers. The title Toei gives this series for international distribution is Galaxy Rangers.

Despite the show's title, only two of the Zyurangers have true Dinosaurs as avatars (Tyrannosaurus and Triceratops). Despite superficial similarities, dragons are mythical creatures, not dinosaurs. Pteranodon (a variety of pterosaur) is a flying reptile from the same time period as dinosaurs (but not technically dinosaurs themselves) and the remaining Zyurangers are prehistoric mammals (Woolly Mammoth and Smilodon).

Every episode of Kyōryū Sentai Zyuranger begins with the statement: "From hundreds of millions of years ago, in the age of the dinosaurs, 5 warriors revive in the present time!" (一億数千万年前の恐竜時代から、今甦った五人の戦士たち Ichiokusū senmannen mae no kyōryū jidai kara, ima yomigaetta gonin no senshi-tachi.?)

Plot
One hundred and seventy million years ago, five ancient human tribes, with the protection of the Guardian Beasts, coexisted peacefully with the dinosaurs. This ended when an evil witch named Bandora started a war on the dinosaurs because of the death of her son Kai. Bandora decided that the only way Kai's death could be avenged was if she sold her soul to Great Satan, an evil entity long defeated by the Guardian Beasts in their original form. In the end, the five tribes were ruined and the dinosaurs became extinct. The Guardian Beasts sealed Bandora and her minions on the planet Nemesis before going into hibernation. In 1992, Nemesis returned to near Earth's orbit. Two Japanese astronauts exploring the planet accidentally released her and her minions from their prison. With Bandora free, her arch-enemy, the wizard Barza retreated to his underground lair 2,000 meters below the apartment building where he worked as a front. There, he revived the five warriors he had been guarding, who had been in suspended animation to be awakened when they were needed. These five were each a member of the ancient human tribes, who co-existed with the dinosaurs. With the aid of the Guardian Beasts, the Zyurangers fought Bandora and her Dora Monsters. Later in the series, after the five have become used to modern times, the leader's elder brother comes forth with tales of jealousy and vengeance.
