Kyōryū Sentai Zyuranger

Kyōryū Sentai Zyuranger (恐竜戦隊 Kyōryū Sentai Jūrenjā, translated into English as Dinosaur Squadron Beast Ranger) is the sixteenth installment in the Super Sentai franchise and the first Super Sentai series to be adapted into 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 Core 5 Zyuranger costumes were used in all three seasons of Mighty Morphin Power Rangers and were used as the original Power Rangers costumes while the Dragon Ranger costume was used as the Green Ranger's costume throughout Season 1 and in early Season 2. Zyuranger was a landmark series with the Super Sentai franchise, being the first series with a prehistoric animal motif, the first to incorporate fantasy elements instead of science fiction, the first to feature a mecha comprised entirely of robotic animals, and the first to feature a sixth ranger character.

A licensed sub was released on February 17, 2015 by Shout! Factory, making it the first fully-subtitled Super Sentai to be officially released in the United States/North America.

Plot
170,000,000 years ago, five ancient human tribes, with the protection of the Guardian Beasts, coexisted with the dinosaurs. This ended when the evil Witch 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 Dai-Satan, an evil, almost ice-like head creature who had immense power and who later in the series could be summoned by Bandora. 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 Earth's orbit. Two astronauts exploring the planet accidentally released her and her minions from their prison. With Bandora free, her arch-enemy, the Mysterious Sage Barza retreated to his underground lair 2,000 meters below the apartment building where he worked as a front. There, he revived the five Holy Warriors of Justice 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 coexisted 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 had become used to modern times, the leader's big brother comes forth with tales of jealousy and vengeance.
