"The lights around it go dark, and a puff of smoke rises from the base. Above in the cylinder, blueish light surrounds a dark mass. Thornlike spikes protrude along one side. The blueish light dims.""

—Narrator^(src)

The Scorpios rex (codenamed E750) was a hybrid dinosaur frozen and held captive in InGen’s secret tunnels on Isla Nublar until it escaped. It was a major antagonist of Jurassic World: Camp Cretaceous, serving as an unseen antagonist of Season 1, the unseen final antagonist of Season 2, the main antagonist of Season 3, and a posthumous antagonist of Seasons 4 and 5. There were two known individuals, with the first one being created by Henry Wu and the second one being asexually reproduced by the original.

Characteristics[]

Physical Traits[]

Eye of the scorpius — Eye of the *Scorpios rex*

The Scorpios rex was depicted as a medium-sized theropod, being smaller than the Indominus rex, a slightly larger than the Indoraptor, but much bigger than the Velociraptor.^[2] The creature's genetic makeup was a mixture of Carnotaurus, Velociraptor, Tyrannosaurus rex, tree frog, and scorpion fish DNA. Of these, the Velociraptor, scorpion fish and Carnotaurus DNA seemed to be the most prominent in having shaped its appearance. Both individuals were adorned with charcoal black scales. Its features were heavily deformed and grotesque, which Simon Masrani determined made it unfit for display. These traits included a brachycephalic muzzle, red eyes with slit pupils set high on its skull, a prominent overbite and jagged, uneven teeth. It had venomous spines on its elbows, tail and neck due to its scorpionfish DNA, which could detach and embed in an opponent's flesh in a manner similar to that of a porcupine. The animal also possessed the signature sickle claws on its inner toes that Velociraptor was known for, which aided in dispatching prey.

Much like Henry Wu's other hybrids, it had opposable thumbs and grasping talons, which enabled it to climb and ambush prey from above. Its semi-prehensile tail also aided it in climbing. Like the Indominus rex, it had infrared vision, which allowed it to see the heat signature of its prey. The Scorpios rex also had a pair of short spurs growing out of the back of its ankles.

The hybrid had the ability to reproduce asexually due to frog DNA. As a result, the single Scorpios rex managed to give birth to another one of its species. Paired with the fact that the Scorpios rex also had accelerated growth, the population of the deadly creature would've increased rapidly if left unchecked.

Behavior[]

"The Scorpios rex's mind has turned out to be as fragmented and unpredictable as its body"

—Henry Wu^(src)

The Scorpios rex displayed indications of neurological and respiratory disorders. According to Kenji's observation, its demeanor displayed a wide spectrum of notable changes, traversing from a state of serenity and tranquility to one of heightened aggression and capriciousness. Additionally, it exhibited respiratory patterns akin to that of a pug, characterized by labor-intensive and effortful breathing. Notwithstanding these afflictions, the hybrid exhibited an exceedingly lethal nature, as it possessed the ability to surpass the speed of a Gallimimus, effortlessly eliminate a Ceratosaurus, and propagate via parthenogenesis.

The Scorpios rex exhibited a parallel behavior to that of the Indominus rex, characterized by indiscriminate aggression and a distinct lack of concern for consequences or ethics. The hybrid frequently simply killed its prey instead of devouring them, resulting in lifeless bodies being strewn about the island. A demonstration of this phenomenon could be observed through the discovery of a Gallimimus ensnared by a tree branch, with the venomous quill of a Scorpios rex still embedded within it. This suggests that the Scorpios rex exhibited a behavior of stockpiling its captured prey for future consumption, or alternatively, that it safeguarded its prey from the threat of competing predators.

The Scorpios rex exhibited a vulnerability towards being easily distracted by noise and displayed a captivating allure towards fire. The hybrid displayed exceptionally aggressive behavior, to the extent that it included instances of parental aggression directed towards their own progeny. Significantly, when a mother and child of similar stature came across each other, they partook in vigorous conflicts that frequently lead to one or both participants enduring severe harm, occasionally even resulting in death.

The avoidance of the Scorpios rex by other carnivores, like Rexy, might be attributed to the presence of the hyper-aggressive behavior displayed by the Scorpios rex, causing wariness among the other carnivores.

Physical Attributes[]

The Scorpios rex showcased an exceptional level of physical prowess, evident through its remarkable agility in swiftly leaping onto and subduing carnivores that shared a comparable size. The formidable prowess of this particular species was demonstrated by its ability to effortlessly overturn a Jeep through the sheer force of a solitary kick. In addition, the Scorpios rex was equipped with highly imposing claws that enabled it to effortlessly eliminate potential dangers, such as the Velociraptor, Blue. Moreover, these formidable claws also granted the Scorpios rex the ability to overpower even larger creatures, such as Parasaurolophus, when executing its pouncing technique.

The Scorpios rex displayed remarkable climbing prowess, showcasing its capacity to effortlessly ascend trees and climb structures within the boundaries of Jurassic Park.

The Scorpios rex also exhibited a noteworthy aptitude for bounding over hindrances, even transcending gates that surpassed its own stature in height.

E750 Antidote — Antidote for poison barbs

The Scorpios rex was armed with venomous quills that were strategically positioned on its tail, along with the top of its its neck and lower arms leading up to the elbow. The venomous spines possessed by these hybrids had the capacity to cause considerable damage. As an example, upon sighting a solitary spine embedded in the hide of a Sinoceratops, the victim exhibited signs of lethargy and debilitation, despite Darius Bowman's successful removal of the tail spine. Furthermore, after Sammy Gutierrez was hit by three of the dinosaur's deadly quills, she came close to the brink of death and would have succumbed to the quills' venom had the antidote not been given in time. The presence of various injuries on a Brachiosaurus, together with its manifestation of disorientation prior to its collapse, suggests the possibility of multiple quills being left embedded. This implies that the dinosaur might have been incapacitated or even fatally affected by the hybrid's venom.

History[]

Creation[]

In 2009, Dr. Henry Wu, under the acknowledgement of Simon Masrani, attempted to create a hybrid dinosaur. The Scorpios rex was the first successful hybrid dinosaur to be created. There may have been many attempts to create the Scorpios rex, as the notes that Brooklynn holds in "The Watering Hole" had incrementing numbers on each page: 1309, 1310, 1311 and, much later in notes, E750. Pages 1309 and 1310 show combinations of the letters used in DNA sequences but are not grouped as DNA sequences. It was the first genetic hybrid dinosaur created by Dr. Wu, preceding the Indominus rex and Indoraptor. Despite many setbacks and Masrani claiming the dinosaur was too grotesque to be put on display, Wu insisted on keeping the hybrid. However, one day, after barely surviving an attack from the hybrid, Wu eventually came to realize that with the Scorpios' mindless aggressiveness, it was far too dangerous to be set loose, let alone placed as a park attraction for the public. With Masrani deeming the creature to be too unstable, Wu shut down the project and kept the Scorpios in a cryogenic suspension indefinitely, intending to never release it, until he could figure out and prove how to make it much less aggressive. This secret was heavily guarded, so very few people actually knew of the hybrid's existence.^[3]^[4]

Jurassic World: Camp Cretaceous[]

Season 1[]

"Secrets" & "Happy Birthday Eddie"[]

When Brooklynn breaks into Henry Wu's lab and searches through his computer, she finds a folder labeled "E750 Clinical Trial Results". Two days later, Eddie indirectly references the Scorpios rex when he was telling the kids that Wu was creating monsters that nobody knew about.

Season 2[]

"Step One" & "Chaos Theory"[]

While investigating an electrical circuit, Kenji Kon was annoyed by a flashing button, which he proceeded to click it until it short-circuited the creature's containment tube, causing the cryogenic chamber to heat up and crack open, also causing the light to turn off. A Compsognathus ripped through a cable which contributed to keeping the Scorpios rex frozen, allowing the hybrid to break free and roam the island.

Season 3[]

At some point after it was freed, the Scorpios rex asexually reproduced at least once, the baby reaching maturity in the wild. As a result of the Scorpios' rampage, the campers notice that the Compsognathus are avoiding their camp and other dinosaurs are acting uncharacteristically, moving to areas they normally would not go.

"View from the Top"[]

A Scorpios finds, ambushes, and successfully kills a Ceratosaurus and then carries it away.

"Safe Harbor"[]

Later that day, one of the Scorpios attacks and kills a pair of Ouranosaurus.

"Casa De Kenji"[]

The next day as it's moving through the jungle, a Scorpios suddenly notices it is being followed by a drone, which the dinosaur promptly destroys.

"Clever Girl"[]

Brooklynn and Sammy find Wu’s computer and learn about the Scorpios and see it attack Wu. Then they realized that it escaped.

"Eye of the Storm"[]

A day later, one of the Scorpios rexes hunts down a Gallimimus and stores it in a tree, where Darius and several other Gallimimuses find its body. Later that day, a Scorpios causes a stampede of dinosaurs, killing a Brachiosaurus during the attack, which unfortunately couldn’t run fast enough to escape the hybrid.

Having learned of the Scorpios rex's existence, the campers create a barricade and an electrified fence around their camp in case of an attack. As night fell and a storm moved onto the island, one of the hybrids follows a herd of Parasaurolophus to the kids camp, killing many of them before being attracted to the camp by the electricity sparking in the rain. With its interest piqued it tests the fence only to find it gets shocked, when this startles the campers, the Scorpios roars to flush them, then jumps over the fence and climbs a tree to get sneak up on them. The dinosaur ambushes the group, hitting Sammy with its venomous quills and cornering many of the campers until lightning strikes a nearby tree, setting it aflame, which mesmerizes the hybrid until the fires dies out. Just before the Scorpios can continue its attack, noise from other dinosaurs grabs its attention and causes it to chase off after them.

"The Long Run"[]

With Sammy poisoned, Yasmina races across the island to find the antivenom, eventually encountering the same Scorpios again feeding on another Parasaurolophus. The dinosaur quickly takes interest in her and roars, which causes her to drop the antidote. Yaz slowly bends over to pick it up in order to not set off the hybrid, and then sprints off with the Scorpios in pursuit. Yaz is chased by the Scorpios rex until she comes to a raging river, which she jumps over but sprains her ankle in the process. The Scorpios easily does the same and easily corner her, but is distracted by Ben and Darius using gasoline to destroy the Gondola Lift in a huge explosion, which lures the hybrid towards it.

"A Shock to the System"[]

Later that night, one of the Scorpios rex attacks a herd of bioluminescent Parasaurolophus lux. It also tries attacking Bumpy, but the herd of Ankylosaurus defends her and drives it off, as their armor is too thick for the hybrid's quills to pierce. The next day, Darius and Ben encounter both Scorpios, which begin circling the pair.

"Escape from Isla Nublar"[]

As the Scorpios circle Darius and Ben, they suddenly attack each other while the boys hide in a limo taken from Kenji Kon's penthouse. The car is knocked about as the hybrids fight, but eventually they both leave the scene. With the danger gone, Darius and Ben reunite with the rest of the group and begin planning out a way to kill the hybrids to halt the damage they cause to the island. To that end, Darius finds a tranquilizer gun in the remains of the old Jurassic Park Visitor Center, but are attacked by one of the Scorpios. Darius tries to shoot it and misses, with the resulting attack catching the attention of the Velociraptor Blue and that of the second Scorpios rex. The three dinosaurs enter a three-way battle that ends up destroying the metal scaffolding supporting the building's roof and causing it to collapse. The campers and Blue notice the collapsing building and escape, but both Scorpios rex fail to notice in their battle and are crushed and killed by the collapsing ceiling.

"Whatever It Takes"[]

That night, Dr. Wu returns to collect his research and the DNA of the Indominus rex for Eli Mills to create the Indoraptor. Returning to the lab the hybrid was stored in, Wu realizes the Scorpios rex escaped and urges his mercenary escort to hurry their mission.

"Stay on Mission"[]

After kidnapping the camper Brooklynn, she informs Wu of the creature's ability to self-reproduce and that she and her friends managed to kill both creatures, both shocking and morally concerning Wu. The next morning, the campers destroy Dr. Wu's laptop containing his research while rescuing Brooklynn, making any hope of recreating the Scorpios rex is lost, rendering it extinct.

Season 4[]

"Rude Awakening"[]

After escaping Isla Nublar, Yasmina experiences a trauma-induced nightmare where the Scorpios rex, Indominus rex, Toro, and a Ceratosaurus surround and kill her.

Season 5[]

"Shaky Ground"[]

While visiting the camp in search of the missing kids, Brandon Bowman steps in one of the Scorpios rex's footprints from the night of its attack on the camp.

Legacy[]

The corpses of the Scorpios rex and any footprints they left behind were most likely wiped away after Mount Sibo erupted on Isla Nublar, officially erasing the hybrid from the face of the Earth.

Jurassic World: Chaos Theory[]

Season 1[]

"Aftershock"[]

When the Nublar Six returned to the mainland, they begin to regale them with tales of their adventures on the island with one of them being when Sammy got poisoned by the Scorpios rex. However, it remains unknown how much they elaborated on the hybrid to the public.

"Free Fall"[]

14 months ago, when Brooklynn was helping Yasmina through Dino Immersion Therapy, flashbacks of the latter's past encounter with dinosaur attacks including ones with the Scorpios rex went through her head as she tried to pet a Stegosaurus.

Trivia[]

The Scorpios rex seems to be the least intelligent of Dr. Wu's hybrids. It gets distracted very easily and lacks a good amount of knowledge as seen when it failed to kill a herd of Ankylosauruses, unlike it's successor, the I. rex who could do exactly that.
In various Jurassic World games, it contains the DNA of Monolophosaurus, Deinonychus and Albertosaurus.
It does share a few similarities with the I. rex: it will attack its own kind, hunts for sport rather than to eat and blinks in the same fashion as the Indominus.
Against common belief, the Scorpios rex is not named after the Skorpiovenator or any kind of scorpion at all; its quills and name come from the scorpionfish.
Dr. Wu confirmed the Scorpios rex was chronologically the "world's first hybrid dinosaur", predating the Indominus rex. This disproves the popular fan theory that the Spinosaurus from Jurassic Park III was a hybrid. The show's executive producer, Scott Kreamer, has confirmed that the Scorpios was Wu's first attempt at hybridizing dinosaurs.^[5]^[6]
The way the Scorpios rex stashes and hunts its prey in trees is similar to how leopards cache their kills and ambush prey on the ground from the trees.
In one of the charts of the Scorpios rex seen in Season 1 says it has a Spinosaurus skull, despite it not having it at all, let alone, not having any Spinosaurus DNA.
The existence of the Scorpios rex is very similar to the Troodon featured in Jurassic Park: The Game. Both are abnormal and venomous creatures that were ordered to be euthanized by the park owner but their creators disagreed and kept them hidden, which later resulted in them wreaking havoc in the island.
The Scorpios rex's design and some of its poses are reminiscent to the human-dinosaur hybrids that were going to be in Jurassic Park IV, but the idea was scrapped.
The Scorpios rex is the first hybrid dinosaur shown to reproduce and also the first ever dinosaur to be shown to reproduce asexually.
Many of the Scorpios rex's sounds are slightly modified versions of that of the Indominus rex.
The Scorpios rex is the only hybrid in the franchise who isn’t known to have killed a human, although it has killed the most dinosaurs.
Multiple sources (such as the novels and executive producers) confirmed that the Scorpios rex is spelled with an "o" and not a "u", because Scorpios is Latin for "scorpion" (although Scorpios is an alternative of the same word in the same language). Regardless, it's officially Scorpios rex, not Scorpius rex.
- To add to the confusion, it was initially spelled Scorpius in Jurassic World: Alive before eventually being corrected in an update^[7]. In the mobile game, it also appears to be bigger than its portrayal in Camp Cretaceous.
It is the first dinosaur to have a Gen 3 in Jurassic World: Alive.
The Scorpios rexes are the only hybrids without any confirmed sex. The Indominus rex was female and the Indoraptor was male. E750 is implicitly female, as parthenogenic organisms tend to be female by default and produce genetically identical female offspring, though the ability of InGen dinosaurs to change their sex leaves this up in the air.
Darius theorized that the Scorpios rex's speed was enough to stretch over all of Isla Nublar in a few seconds (making the Scorpios having a top speed of about 26,389.54 mph) but that got debunked as of the episode "A Shock to the System".
The Scorpios rex also shares the ability to climb with the Indoraptor, the only hybrids to do so.
