Camp Cretaceous season 3 introduces the Scorpios Rex, a hybrid dinosaur that's the deadly forerunner to Jurassic World's Indominus Rex and Indoraptor.

Warning: SPOILERS for Jurassic World: Camp Cretaceous season 3.

Jurassic World: Camp Cretaceous season 3 introduced the Scorpios Rex, a horrific new hybrid dinosaur that was actually the forerunner to Jurassic World's Indominus Rex and Jurassic World: Fallen Kingdom's Indoraptor. Created by Dr. Henry Wu (Greg Chun), Scorpios Rex is a technological terror that rampages in Isla Nublar in the months after the Indominus Rex caused the theme park's destruction and evacuation in Jurassic World.

The Scorpios Rex was teased at the end of Camp Cretaceous season 2; she was held in cryo-stasis in Dr. Wu's underground lab but was accidentally released by the teenage Campers stranded on Isla Nublar, though it would be months before they encountered the hybrid dino. By Camp Cretaceous season 3, there were two Scorpios Rex on Isla Nublar as the original was able to breed. Later, Brooklynn (Jenna Ortega) and Sammy (Raini Rodriguez) saw Dr. Wu's research, designated as the E750 project. The kids learned about the creation of the Scorpios Rex, which proved too uncontrollable. The hybrid beast even attacked and nearly killed Wu, poisoning the geneticist, who survived thanks to an antidote he developed. Despite his ordeal with his monstrous creation, Wu refused to destroy the Scorpios Rex and had her placed in stasis so he could create an "improved" version one day. Once loose on the island, the Scorpios Rex and her child unbalanced the natural order, killing and terrifying the various carnivores and herbivores in Jurassic World.

Since the Scorpios Rex predated the Indominus Rex and the Indoraptor, she contains aspects of both, although she was a failed experiment too dangerous to let loose in the wild. The Scorpios Rex's size is somewhere between the Indoraptor and the Indominus Rex, which allows her to enter buildings and even squeeze into tunnels. Like the other hybrids, the Scorpios Rex contains Velociraptor DNA to make her a deadly predator. Similar to the Indoraptor, Scorpios Rex has hands with an opposable thumb, three fingers, and claws. She can also leap like the Indoraptor, thanks to her Velociraptor DNA, and the Scorpios Rex can even climb trees, as the Campers found out when the hybrid clambered up to attack them in their Camp Cretaceous treehouse. The Scorpios Rex and the Indoraptor both have night vision but the red-eyed Scorpios is also attracted to fire and bright flame.

The Scorpios Rex's most potent weapons are her poison quills, which come from the top of her head and her tail. Dr. Wu used scorpionfish DNA to create the Scorpios Rex (and he named his dinosaur after it). The hybrid's poison can bring down even the largest cerapods in Jurassic World. When Sammy was poisoned by the Scorpios Rex's quills, Yasmina (Kausar Mohammad) only had an hour to race to Dr. Wu's lab to retrieve the life-saving antidote.

Thanks to Blue the Velociraptor's help, the Campers were able to kill both Scorpios Rex by collapsing the old Jurassic Park visitor's center on top of the hybrid dinosaurs' heads. It's notable that despite being from the same family, both of mindless, vicious Scorpios Rex showed no affinity to her 'pack', unlike the Velociraptors or the other dinosaurs in Jurassic World. Instead, each Scorpios Rex identified the other as her enemy and they tried to kill each other with the same ferocity they attack everything else.

Hybrid dinosaurs and the dangers they pose are a running theme in the Jurassic World franchise. Camp Cretaceous season 3's retcon shows that Dr. Wu's first hybrid was arguably his most abominable creation, one that Simon Masrani (Irrfan Khan) ordered destroyed because it was too deadly and grotesque to place in a theme park full of visiting families. Yet Dr. Wu refused and his attempts to 'improve' on the Scorpios Rex only created new but similar horrors. But compared to Indominus Rex and the Indoraptor, Jurassic World: Camp Cretaceous' Scorpios Rex may be the worst hybrid dinosaur of all.
