The Dinosaurs and the Raptors are evolved and made intelligent by Argor Zardok, an evil scientist from the extra dimensional world of Quadrania. After Bad Rap sets off the Ice Age, the Dinoraus and Quadranian Police Captain Chedra Bodzak - and the Raptors - spend 65 million years in Chedra's Quadranian freeze chambers. They're revived in the present by unscrupulous scientist Peter Benning, and the captured by Dr. Becky Scarwell and her top secret government task force. The Dinosaurs must escape from Scarwell's Roswell installation in time to do battle with the Raptors...

Now that they know they're the world's last surviving dinosaurs, the Extreme Dinosaurs get acquainted with everything the 20th century has to offer: the Home Shopping channel, and spicy Mexican food! Meanwhile the Raptors discover oil, and realize they can burn it to heat things up all over the globe - leading to a climactic battle with the Extreme Ones, where the Dinosaurs must stop the Raptors from igniting the oil deposits beneath Los Angeles' La Brea Tar Pits.

The Dinosaurs win a TV contest and travel to Mexico to collect their prize: a vacation in a tropical paradise. Unfortunately, they're in for a rude surprise when they discover the contest is a trap staged by the Raptors! The Raptors turn T-Bone, Stegz and Spike over to Dr. Becky Scarwell, and it's up to Bullzeye to rescue his friends from Roswell before they become guinea pigs in Scarwell's experiments.

Bad Rap has found a whole cache of raptor eggs, and before long, he'll have an entire army of nasty, rotten Velociraptors! Now, he's especially determined to warm up the Earth to make it home for his vicious "children". But when the Dinosaurs capture one of the eggs, they discover that it's not quite what it seems.

When top scientist Carl Wiseman announces that a gigantic asteroid hurtling towards Earth will miss completely, Stegz is suspicious - his calculations say it's going to sideswipe the Earth, causing terrible damage! The Dinosaurs are right to be suspicious: the Raptors forced Wiseman to lie and then kidnapped him to keep him from warning everyone. They think the asteroid impact will push Earth closer to the sun, making it a lot warmer .... too warm for humans, but just right for Raptors! The Extreme Ones must rescue Wiseman from the Raptors, and find a way to stop the asteroid before it's too late.

Stegz receives a signal from intelligent dinosaurs in another dimension, leading the Extreme Ones to the desert for a rendez-vous with some extra-dimensional cousins. It turns out to be a set-up by the Raptors, who ambush the Dinosaurs and set out to burn a hole through the Earth's surface, releasing the heat of the molten interior.

It's flu season for our heroes, when the Raptors synthesize a 65 million year old germ that gives the Dinosaurs a nasty case of the Jurassic Flu! While the Extreme Ones are bedridden, the Raptors steal an Extreme artificial material that produces intense heat when exposed to sunlight.

The Raptors' new plan to heat up the Earth becomes more complicated when Spittor discovers his artistic side. A chemical splotch he left on the wall of the Louvre during a battle with the Dinosaurs has caught the eye of critics, and now Spittor is the darling of the art world! But Bad Rap has a plan to use Spittor's first art show as a trap, to put the Extreme Ones out of commission while the Raptors change the Earth's magnetic field (using the Eiffel Tower as an antenna) and melt the polar ice caps.

The Raptors enlist the help of a unscrupulous computer technician to take control of the world's submarine forces, so they can use the subs to set off underwater volcanoes all over the world.

Peter Benning gets a job designing the Dinosaur Safari amusement park, hoping to draw the interest of the Extreme Dinosaurs so he can capture them. He gets more than he bargained for, though, when the Raptors take control of the park's robotic dinosaurs. The Extreme Ones must avoid Benning's traps and defend themselves - and Benning - from Bad Rap's new army of Cyber-Raptors.

The Extreme Ones journey to Scotland in search of the Loch Ness Monster - if "Nessie" really is a dinosaur, she might be a long-lost relative! Unfortunately, the Raptors have beat them to it, and are busy training the enormous monster to attack the Dinosaurs on sight.

When Bullzeye orders a new exercise machine called the Immortalizer from the Home Shopping Centre, he doesn't realize it's part of an elaborate Raptor scheme - the Immortalizer is a robot, sent to plant information in the Dinosaur's computer that will lead them into a trap. The Raptors have stolen a substance called Fire-Ice, which will let them heat up the atmosphere and put the Dinosaurs in deep-freeze at the same time.

When the Raptors hear about the Eco-Dome, a climate-controlled habitat for nearly-extinct plant species, they decide to make it their new home. It's up to the Extreme Dinosaurs, with the help of a young girl named Danielle, to evict the Raptors before they can destroy all of the Dome's rare, endangered plants.

The small Middle Eastern nation of Bawa-Idabi is taken over by the unbalanced General Amadi and his three "genies" - Bad Rap, Haxx and Spittor! The Raptors are helping Amadi corner the world's oil market so people will be forced to buy Spittor's special super-polluting gasoline, which will speed up global warming. It's up to the Dinosaurs and Chedra to pull the rug - or the magic carpet - out from under the Raptors' plan, and restore Bawa-Idabi's rightfully elected president.

While studying up on Earth Law, Chedra makes a date with C.P. Buchanan, a lawyer who's just as obsessed with rules as she is. Unfortunately, C.P. has been blackmailed by the Raptors into stealing Chedra's Quadranian code book, so they can learn the Dinosaurs' battle tactics and anticipate their every move! The Extreme Ones must find a new strategy to beat the Raptors and rescue C.P.

When Spike is separated from his friends while chasing the Raptors, he's "discovered" by a wrestling promoter who wants to make him a star. Spike becomes "Terror-Dactyl", the newest professional wrestling sensation, battling monster trucks because human wrestlers turn out to be too easy! Bad Rap decides to build a challenger, Monstersaurus Truckadon, to humiliate Spike on TV, while the Raptors set off a chain of volcanoes to change the world's weather patterns.

When the Raptors steal a drone aircraft and try to defoliate the rain forests (in hope that it will speed up global warming) the Extreme Dinosaurs set out to stop them.

Bad Rap has a powerful new device that he's going to use to blast the Moon into the Earth, knocking it closer to the Sun.

The Raptors and the Dinosaurs discover Argor Zardok's inter-dimensional cruiser, which Bad Rap uses to send them all to a hot, tropical dimension, full of raptors.

The skeletons of four dinosaurs, unearthed by a Florida construction company, come to life and go on a rampage through downtown Miami. The Extreme Ones try to stop them, but they find out it won't be easy: when they've been smashed, these "Skelesauruses" reassemble themselves into one enormous "Megasaur"! To make things worse, the Raptors have unleashed a new and even meaner generation of Cyber-Raptors. It's Megasaur vs.

The Raptors have caused New York City to be overrun by gigantic, mutant vegetation: plants that release ozone-destroying fluorocarbons instead of oxygen.

After watching too many bad science fiction movies, Bad Rap hits on the perfect scheme to wrest control of the Earth from the humans: steal a flying saucer (from Becky Scarwell's Roswell installation) and stage his own alien invasion.

The Dinosaurs discover the joys of motorcycles, and before long they're outfitted with sunglasses, leather jackets and rocket-powered trikes. Meanwhile the Raptors have stolen a powerful experimental ozone-destroying laser and captured Becky Scarwell to help them use it.

The Raptors use their mammal-repelling Sonic Repulsator to drive the humans off the tropic island of Razambique, so they can buy it for cheap and turn it into their own private Raptor paradise! The Dinosaurs set out to evict the reptilian real estate moguls, but the special computer chip that will let them stop the Repulsator is with Bullzeye - who has wandered away with temporary amnesia, convinced that he's really a giant talking condor!

When an old archaeologist heads into the jungles of Central America in search of the last of nine ancient tablets, the Extreme Ones and the Raptors each set out to follow him. The first eight tablets prophesied the return of the dinosaurs and the ninth is supposed to be a magical object that will control their ultimate fate! The "archaeologist" turns out to be Peter Benning in disguise, but the magic object is all too real, and the Dinosaurs must fight their way through a maze of traps and pitfalls to find it before Bad Rap does.
