Sixty-five million years ago an evil, alien scientist named Argor Zardok visited prehistoric Earth through a trans-dimensional gateway. Surprised to find dinosaurs in evidence, he hit on the idea of using the dinosaurs to assist in his ambitions for conquest against his Quadrainian home world. Using advanced technology, he mutated four dinosaurs and imbued them with special abilities. But when Argor attempted to command the dinosaurs he discovered he had given them too much intelligence. The dinosaurs quickly deduced why he had created them and pitted themselves against him.
Ditching his first, failed batch of dinosaurs, Argor transformed three new dinosaurs; this time making them less intelligent, but more vicious and open to suggestion. He also outfitted them with futuristic weapons. Finding his new creations more amenable, he set about creating an entire army of dinosaur minions.
Meanwhile, hot on Argor’s trail was fellow Quadrainian, Captain Chedra Bodzak, a no-nonsense officer of the law who stuck to the regulations set down by the codebook she carried and constantly consulted.
Before Argor could make any real headway on his dino-army, his first two groups of mutated dinosaurs—the Extreme Dinosaurs and the vicious Raptor Gang—faced off against one another. In the wake of their struggle, one of the raptor’s weapons started an atmospheric chain reaction that hurdled prehistoric earth into the next Ice Age. To escape the planet-wide devastation, Chedra and both groups of dinosaurs took refuge in deep-freeze chambers aboard Chedra’s damaged alien craft, while Argor abandoned his creations and fled back to his own dimension.
Fast forwarding 65 million years to the late 20th century, archaeologists discovered the spaceship and unwittingly activated the cryo-chambers, reviving the dinosaurs and releasing them on the modern world. The Raptor Gang—made up of Bad Rap, Spittor and Haxx (all Velociraptors)—continued their evil ways, while Chedra and the Extreme Dinosaurs—consisting of T-Bone (a Tyrannosaurus Rex, and the leader of the team), Bullzeye (an excitable Pteradon who was addicted to infomercials and a compulsive spender), Spike (a Triceratops who provided brawn and muscle), and Stegz (a Stegosaurus who was the intellectual of the bunch)—teamed up to stop the Raptors.
T-Bone and his gang, along with Chedra, set up a base of operations at a remote, roadside dinosaur museum run by Porcupine McVells, who wasn’t overly surprised when confronted with living dinosaurs and an alien because he lived in the vicinity of Roswell and was used to seeing oddities. In addition to the problems created by the Raptor Gang, and the chiding the Extreme Dinosaurs had to face from Chedra every time they even remotely broke an edict set forth by her codebook (which, coincidentally, was 65 million years out of date and from another dimension to boot!), the Extreme Dinosaurs were also forced to elude Dr. Becky Scarwell and her top secret government task force, who considered dinosaurs running free a threat to the nation’s security and welfare.
The tone of the series was similar to that of Teenage Mutant Ninja Turtles, where the levity of light-hearted banter kept the stories from becoming overly serious, while providing enough butt kicking action to keep die-hard action fans happy. The show originally aired for one season consisting of 52 episodes, although more can be seen of the dinosaurs by watching the last few episodes of the series Street Sharks, where they made their initial appearance.
