Five young warriors from the ancient civilization of Dinosaur-evolved Humans are awakened in 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 the Guardian Beasts, each modeled after a different prehistoric beast, in order to protect mankind from Bandora's evil forces.
170 million years ago, Dinosaurs and humans lived side by side in peace and harmony. One day however, a mischievous troublemaker by the name of Kai breaks several dinosaur eggs and as such is chased off a cliff by a dinosaur. Kai's mother, a woman named Bandora, sees her son get chased off a cliff but does not see what had happened before that. Enraged, Bandora asks Satan himself to give her the power to destroy every last dinosaur on Earth. Bandora gets the power but she pays a terrible price for it: her sanity. Bandora becomes the evil Queen Bandora and after recruiting the help of Grifforza (Goldar), Puipuiin (Finster), Lammy (Scorpina), BakuBaku (Squatt), and Tatutattin (Baboo), begins her relentless attack on the dinosaurs, determined to wipe them out of existance. The great wizard Barza (what Zordon was supposed to be before he got trapped in a time warp) could not stand the terrible destruction plaguing the dinosaurs. He recruited five special people from five special king
The Zyurangers must rescue the astronauts who freed Queen Bandora . It's up to Geki's Tyranosaurus protector beast to save the day.
The Zyurangers decide that in order to defeat Queen Bandora's evil plans, they need to get the Legendary weapons from the Land of Despair. There's just one catch though: if they stay there for longer than 24 hours, they will turn into stone. Queen Bandora decides to send down Grifforza and some clay soldiers down to the Land of Despair as well, determined to make sure that the Zyuranger's first day in the Land of Despair is also their last.
The Zyurangers successfully complete their mission to get the legendary weapons from the Land of Despair. After transforming, they make short work of Dora Minotaurus. Queen Bandora destroys the Land of Despair, enraged that her plan to destroy the Zyurangers did not work.

The rangers must use their new power to combine their guardians beasts and defeat DoraSphynx and Grifforzer...

A mysterious man named Burai is awakened from a long slumber and reveals to the ZyuRangers that he has their powers as well! However, Burai doesn't attack Queen Bandora's forces, he attacks the ZyuRangers themselves! What kind of a grudge does Burai hold against the ZyuRangers that would make him want to attack them?
Burai seeks out Queen Bandora and asks her for the strength to destroy the ZyuRangers. Burai wants revenge against the ZyuRangers as his brother is the Red ZyuRanger and long ago, Burai was taken away from his birth father and given to King Yamamoto (the Dark Warrior) as a consolation prize when the King won a battle against Burai's father. Burai swore revenge against his brother and swore to beat him in battle while the Great War against Queen Bandora was being waged. However, the War ended to quickly and Burai never got the chance to prove himself. He followed the other ZyuRanger's into a hypersleep and has finally been reawakened. Queen Bandora tells Burai that the Savage Sword will give Burai all the strength he needs to destroy the ZyuRangers but forgets to mention to Burai one tiny detail: the Savage Sword makes whoever is currently wielding it completely insane, and Burai is already unstable as it is! With the Savage Sword in Burai's hands, do the ZyuRangers even stand a cha
Things aren't going well for the ZyuRangers. When the Red ZyuRanger finds out that Burai is his brother, he is unable to fight to his full potential out of fear that he could hurt his brother. To make matters worse, Queen Bandora has resurrected Lammy out of a 65 million year slumber, in order to help Burai in a final battle against the ZyuRangers.
Lammy and Grifforza commence their attack on Japan to bring about the end of the ZyuRangers. The Zyuranger call upon their mechas to do battle but there are three big problems. One, Lammy and Grifforza are holding a schoolbus full of children hostage and threaten to throw the bus off a cliff should the ZyuRangers make one false move. Two: today there is a solar eclipse occuring which means that Daizyuzin's (Megazord's) power will be at its absolute minimum. Three: Queen Bandora has grown Grifforza, Lammy, and Burai to monster size. The ZyuRangers manage to make the rescue of the schoolbus and their children, yet the Red ZyuRanger just doesn't have the heart to fight against his brother Burai. Because of this, Daizyujin get's beat up badly. So badly in fact, that Daizyuzin breaks apart and falls into a pool of lava that has opened in the Earth's crust! The ZyuRanger's cannot believe what they're seeing! Their most trusted friend, Daizyuzin, has seemingly been destroyed right before
Queen Bandora and her evil crew are celebrating their victory over the ZyuRangers. However, all is not well. Burai, consumed by his lust for power because of the Savage Sword, tries to destroy Queen Bandora herself! Queen Bandora proves to be more powerful than Burai could of ever thought possible, and Burai is banished to Earth. Once there, Burai encounter's a child-like being named Clotho, who reveals herself to be the keeper of life and death. (In other words, she determines how long a person lives.) She explains to Burai that when he went into hypersleep 170 million years ago, an earthquake had occured between that long span of time, and caused a landslide of rocks where Burai had been hypersleeping which killed him! Burai's companion mecha Dragon Ceaser however, couldn't stand being alone without Burai, and pleaded with Clotho to give Burai his life back. Clotho agreed but with a catch: Burai has only 48 hours left to live before his lifeforce (represented by a green candle) c
The Great Wizard Barza, using his own special brand of magic, manages to bring back Daizyuzin out of the lava. Ironic- ally enough, the lava made Daizyujin stronger and now the Red Zyuranger Geki is ready to end Burai's rampage once and for all. All by himself, Geki beat up Dragon Ceasar as a punishment for attacking his fellow ancient beast spirits, and then blasted Geki right out of his Dragon Ranger armor. Burai, unable to move, is at the mercy of Geki. Daizyuzin orders Geki to strike Burai down, yet even after everything that Burai has done, Geki refuses to do so. In a mad burst of adrenaline, Burai tries to strike Geki down, only to hear Geki say something like this: ""If It will help, if it will take away the pain, then by all means kill me."" Upon hearing these words, Burai drops the Savage Sword and breaks into tears which completely disintegrates the Savage Sword, freeing Burai from his insane rage.

Burai is given some depressing news by Clotho: he only has five hours left to live. Even worse: the next time Burai leaves the Lapseless Room, he won't be able to return. Queen Bandora overhears this juicy information and comands Puipuiin to create DoraFake, a monster capable of making it look like it is something else than what it really is. DoraFake transforms itself into Dragon Ceaser, and Queen Bandora flies down to Earth to tell the ZyuRangers that SHE'S in control of Dragon Ceaser now. The ZyuRanger's try their best to handle DoraFake, but eventually, they NEED Burai's help, BADLY! Burai decides to hurry to help the other ZyuRangers. Burai tries to gain recontrol of Dragon Ceaser, only to discover that what's attacking Daizyujin isn't Dragon Ceaser at all but merely DoraFake mimicking Dragon Ceaser. After Burai calls upon the real Dragon Ceaser, he and the other ZyuRangers make short work of DoraFake. Burai immediately hurries back to the Lapseless Room, but Queen Bando
Trying as hard as Burai can, he cannot reach the Lapseless Room in time, nor can he stop Queen Bandora from destroying it. Adding insult to injury, Queen Bandora flies off with his Green Candle, claiming that he has only four hours left to live. Burai however, is no longer concerned for his life, he's concerned about someone elses. Burai has had a very disturbing vision about a young boy dying soon after Burai dies, and Burai goes off to find him, which he does. Burai is pleasantly surprised however, that the boy he's been looking for is perfectly fine and in perfect health. Burai decides to spend his last four hours hanging out with the kid, showing him the time of both their lifes on top of Dragon Caesar. The other Zyurangers, desperate for a way to save Burai's life, decide to go to the Sacred Land of the Dinosaurs, which is said to contain a magical water that can revive anyone near the brink of death. There's just one catch though: the other Zyuranger's won't be able to mo
Burai might be hopelessly outmatched by Dora Fake, but knowing that he's going to die anyways, decides to go out the same way he came in, and fights like there's no tomorrow. The other Zyurangers suddenly find themselves with their powers back, meaning that Dan and Goushi have succeeded in their mission. The other Zyurangers form the true Daizyujin and finish off DoraFake once and for all. The victory is bittersweet however, as Burai's lifeforce is almost completely gone. Clotho appears to the Zyurangers informing them that even though they succeeded in their mission, the water of the gods will not be able to restore Burai's life as he has already died once and the life he has been living with the other Zyuranger's was a temporary one. So with Burai's last request, he bestows the Dragon Armor and Dragon sword to his brother Geki, so that Geki can command Dragon Caesar, and asks the Zyurangers to give the magical water to the boy he had saved earlier so that even though Burai will d
