Even before the history began, fierce battles between god and Satan over the
supremacy had taken place on Earth continually. Their battle seemed to last forever,
yet finally god defeated Satan and dispelled him to hell. Although severely damaged
god lost his ultimate and immaculate form, and was broken down into seven
Shogozyus.
Later in the dinosaur era--early mankind already existed in the Earth. Consisting of
five tribes, those ancient people developed civilization and enjoyed peaceful livings.
Then the repulsive sorceress Bandora appeared and started the war against humans.
With her massive power, Bandora devastated the Earth and destroyed the lives of
almost completely--until five shogozyus, which ancient people worshiped as their
gods, emerged onto the Earth to save the world; Bandora, along with her four
henchmen, was captured and sealed onto a deserted planet. However, heads of
the five tribes, anxious about the possible return of Bandora,selected the best
warrior from each tribe, and put the chosen five into suspended animation to
safeguard the future world.
...and 170 million years have passed.
Humans now have developed enough civilization and technologies to explore
one planet approaching to the Earth-- and eventually, they have broken the seal
of Bandora. Revived Bandora settles on the moon and targets the Earth once
again. Yet, the five warriors from the past-- Geki, Goushi, Dan, Boy, and Mei--
make their returns as well. They team up as the mighty heroes called Zyurangers,
and stand up against Bandora's ambition.
Zyurangers have two missions; the first is to fight against the evil and protect the
lives on Earth and the second is to find the pair of dinosaur eggs preserved
secretly to this date. Zyurangers experience numerous battles and challenges
after another on their missions; they obtained Legendary Weapons, activated
Dinotankor and Daizyujin, and so on. Zyurangers and Daizyujin have
successfully kept Bandora's evil plans fruitless, although they have lost trace
of the Dinosaur egg during the battle.
Then along came a twist: Burai, Geki's older brother, gets himself released from
suspended animation. Yet Burai is obsessed with hate for Geki; Burai even
cooperates with Bandora and assults Zyurangers. After intense battles Burai
comes back to his humane self, and Zyurangers get strong new allies--Burai
his Shogozyu Dragon Caesar, and Gouryuujin. However, Zyurangers are not
aware that Burai's life is already running short...
Bandora yet strikes back; she executes the ultimate black magic to bring Satan
from the hell. Satan descends on the Earth to wreak havoc, and his massive
power overwhelms Daizyujin. Finally, Zyurangers succeed to revive Kyuukyoku
Daizyujin, immaculate form of ancient god, and dispel Satan from Earth for once.
During the battle, however, Burai secret gets revealed to others, including
Bandora. Bandora targets Burai ever since, and despite of Zyurangers' desperate
efforts, Burai ends his young life.
In turn, Zyurangers finally get the Dinosaur eggs back under their protection.
When the eggs are about to hatch, Bandora brings out her final battle against
humans and Zyurangers. Bandora summons Satan once again, and Zyurangers
face the unprecedented crisis because they lose their powers and Shogozyus.
Zyurangers yet do not give up on their hopes; they rescue their Shogozyus and
regain their powers, and Kyuukyoku Daizyujin defeats Satan at last. Bandora
and her gang are sealed again, and as peace finally arrives on Earth, Zyurangers
successfully complete their mission and depart to the land of gods.
