Kyoryu Sentai Zyuranger (Dinosaur Squadron Beastranger) is the sixteenth entry in the Super Sentai franchise, which aired from 1992 to 1993.
170 million years ago, humans lived in peace with dinosaurs, until the evil witch Bandora appeared, killed the dinosaurs, and began to attack humanity. The Guardian Beasts, great gods in the form of prehistoric-animal-shaped Humongous Mecha, sealed her away on the stray planet Nemesis. In modern times, astronauts exploring Nemesis accidentally release Bandora and her followers from captivity, and she again starts to attempt to kill humanity, starting with the children. The ancient wizard Barza, in disguise as a landlord, releases five warriors from the five prehistoric human tribes to fight Bandora's forces alongside the Guardian Beasts.
