Antagonists Wiki

We have a T-rex.
~ John Hammond

Rexy, also known as Roberta, the Tyrannosaurus rex of Isla Nublar or simply known as the T. rex, is the anti heroine of the Jurassic Park franchise, appearing as a major antagonist in Jurassic Park, Jurassic Park: The Game, and Jurassic World: Camp Cretaceous; a major character in Jurassic World; a minor character in Jurassic World: Fallen Kingdom; and the main dinosaur protagonist in Jurassic World: Dominion.

She is a genetically recreated female Tyrannosaurus rex who served as the queen of Isla Nublar and was originally created for display at Jurassic Park until she eventually went on to become and exhibit at Jurassic World for over 10 years. Rexy is also known for participating in several incidents on Isla Nublar as well as for saving major human participants involved in these incidents from other dangerous creatures, although inadvertently.



The Tyrannosaurus was born around 1988, inside the InGen Compound of Isla Sorna (Site B), along with another Tyrannosaurus. It was at this compound where Rexy spent the first few months of her life inside the lab being taken care of by her handlers before she was transported to Isla Nublar to live in the Tyrannosaurus Paddock as an attraction for Jurassic Park.

Jurassic Park

When the inspection team constituting of vertebrate paleontologist Dr. Alan Grant, paleobotanist Dr. Ellie Sattler, chaotician Dr. Ian Malcolm, lawyer Donald Gennaro, and John Hammond’s grandchildren Lex Murphy and Tim Murphy took a tour of the Park, the Tyrannosaurus was initially a no-show. Although computer technician Ray Arnold attempted to lure Rexy to her paddock fence by tantalizing her with a goat, however, she still refused to appear.

Later that night, a tropical storm forced the tour to be turned around sometime after the group visited the Triceratops Paddock. Unfortunately, due to Dennis Nedry’s tampering with the programming, the tour vehicles that the tour group was in, shut down in front of the paddock with its electrified fencing also shut down. Tim then observed water in a cup having rhythmic ripples caused by Rexy walking close by, then noticed the goat was gone, at which point Lex asked: “Where’s the goat?” Rexy then revealed herself to the visitors by ripping apart the goat left by the fence as bait. Gennaro, in a fit of panic, left his tour car and ran to the nearby restroom hut for refuge. By that point, the Tyrannosaurus moved to the disabled fencing and ripped the fencing apart with her jaws before proceeding to step through her mangled handy work. After a minute or two of inspecting and investigating the Explorers, her attention was aroused by the light that was emitted from a flashlight Lex had activated on accident in the front Explorer. Unaware that the source of the light was inside the car, she walked to the front door Gennaro left open and peered into the front doors of the SUV. It was not until Tim slammed the open door shut next to the T. rex that she had discovered the source of the light.

Now confident that the light was coming from inside the Explorer and that there were two interesting objects inside, Rexy set to attacking the mysterious vehicle in front of her, searching for a way to get at Lex and Tim. Thanks to the efforts of Dr. Grant and Dr. Malcolm, the T. rex was briefly distracted. Rexy followed fleeing Dr. Malcolm toward the Tyrannosaurus Paddock Bathroom, injured him as he was flung into the building, she then found and ripped apart the cowering Gennaro while Dr. Grant rescued Lex from inside the car, not long after freeing Lex, Rexy returned and pushed the vehicle over the cliff while Tim was still inside. After Dr. Grant rescued Tim from the tree, the two with Lex, began their trek back to the Visitors Center, Park game warden Robert Muldoon and Dr. Sattler arrived at the Tyrannosaurus Paddock to retrieve those who had been stranded there only to find Rexy's mess. Acting quickly, the two began searching for the group and calling out their names. At the site of the collapsed restroom hut, Muldoon and Dr. Sattler found the remains of Donald Genarro and recovered Dr. Malcolm who was quite injured, but alive due to his quick thinking to reduce blood loss by using his belt as a tourniquet. After loading Dr. Malcolm into their Jeep, the two took one last sweep of the area, Dr. Sattler spotted the ruined hulk of the second tour car that Rexy had pushed over the cliff adjacent to her Paddock. Although Muldoon and Dr. Sattler did not find Tim, Lex, or Dr. Grant, they did find their shoe prints in the mud, which told them that they were indeed alive. While the two were gone, Dr. Malcolm observed the water in Rexy’s footprints having rhythmic ripples, announcing her close presence. When the two returned to the Jeep, Rexy crashed through a line of trees due to her larger size and began chasing the three along a service road. After a very close chase, the Tyrannosaurus was unable to chase down her prey and abandoned the pursuit.

The next day, as Grant’s, Tim’s, and Lex’s trek continued, they found themselves in the Gallimimus Enclosure and witnessed Rexy hunting a herd of them. After watching in amazement for a while from behind a fallen log, Lex begged Dr. Grant for them to go, to which Grant obliged. However, Tim continued to stare in fascination and so had to be forcibly taken away by Dr. Grant. Rexy was seen later that day when she actually followed a raptor that had come through the plaster cover in the wall, and grabbed it from mid-air just as it was to pounce on the humans, proceeding to crush it in her jaws. Using the distraction Rexy provided, the humans fled the island. Meanwhile, the alpha-female raptor, who was The Big One that pursued the group through the Visitors Center, foolishly attacked the larger theropod as revenge for killing her partner. Rexy snapped at her but could not reach her. She instead rolled her head, and The Big One fell into the T. rex's mouth, where she is crushed in her jaws before getting thrown against a Tyrannosaurus skeleton on display. Afterwards, Rexy now roams around Isla Nublar as the apex predator of the island.

Jurassic Park: The Game

During that night of another tropical storm, Rexy began wandering farther from her paddock area. As Dr. Gerry Harding and his daughter, Jess Harding, were heading for the boat to the mainland after Gerry returned to the site of a sick Triceratops to pick up Jess in his gas powered jeep, they found Nima Cruz, a corporate spy who went to search for Nedry after he failed to arrive at the East Dock. As the three made their way, they come across Bahkita, an infant Triceratops that was out of her paddock. They managed to get the dinosaur back into her enclosure, but Lady Margaret, the alpha female, appeared and attacked, which also attracted the attention of Rexy, who confronted Lady Margaret. The group barely managed to escape, hiding in a maintenance shed while the dinosaurs fought and decided to spend the night inside. It is unknown what was the outcome of this fight, but it is known that Rexy survived and that Lady Margaret lost one of her horns.

Later, she returned when Dr. Gerry Harding, Jess, and Nima Cruz reached the Visitors Center, unaware that the survivors had already fled and left the island. While the humans were inside, Dr. Harding spoke with Dr. Laura Sorkin over the radio, who helped cure Nima of her ailment caused by a Troodon bite. Rexy attacked once again, forcing the trio to avoid her as best they could while Gerry tried to stop Nima from shaking and Jess used the center's pillars to stay hidden. To get the Tyrannosaurus' attention, Gerry dropped a box that hit Rexy on the back. Jess grabbed the tranquilizer darts and ran upstairs to help Gerry where they healed Nima. Rexy proceeded to follow Jess up the stairs, but due to the theropod's massive size and weight, the staircase collapsed, causing her to fall and crash to the floor. When Rexy regained balance, the vibration of her feet caused Jess to fall while the trio was escaped just outside on the roof.

Even though Jess caught a ledge preventing her falling, she soon lost her grip and fell further down, now hanging onto the door frame. Dr. Harding came down from the roof to help her though soon Rexy charged through the doors, knocking Dr. Harding back. The predator then snapped at Jessica as she dangled from the door frame. As Dr. Harding grabbed his tranquilizer gun, Jessica finally lost balance and landed on top of Rexy's snout, which prompted the Tyrannosaurus to shake Jess off. Nima, fully recovered now, tossed the tranq darts to Dr. Harding, who shot Rexy in the face three times, saving Jess from potentially being eaten. However, her retaliation was quick and she soon charged through the door frame, destroying it. Rexy then proceeded to attack the tour vehicle that the Hardings were behind using as shelter. The T. rex's attack on the Hardings finally came to an end when Dr. Harding told Dr. Sorkin to start the tour vehicle, which distracted Rexy.

After a second mercenary team landed on the island to rescue those who had been left behind and retrieved the survivors, the group headed back to the helicopter, but found that mercenary Daniel Cafaro had disappeared. Rexy reappeared and made her way towards them, forcing another mercenary Oscar Morales to fix the chopper himself. She finally reached them just as they managed to get the helicopter working again. As the helicopter was taking off, Rexy nudged it with her head, causing the aircraft to swerve, but lead mercenary Billy Yoder ultimately piloted the helicopter to safety and evaded the dinosaur.

After Jess helped Dr. Sorkin in the Parasaurolophus Enclosure and Nima got into a fight with Billy Yoder, who was sitting in a tree, Rexy appeared again, chasing a juvenile Parasaur, but then Yoder almost fell, although he grabbed a branch in order to save himself. The T. rex, having noticed this, picked up a piece of helicopter wreckage with her jaws, and launched it at Yoder in an attempt to knock him out of the tree. Yoder let go at the last second and landed hard on the forest floor. Then he and Nima began to run away from Rexy as she catches up to them towards the Parasaur Paddock. Inside, Rexy became distracted with a Parasaurolophus carcass and briefly during the feeding, killed a Velociraptor that had also been eating the carcass as well when it attempted to escape. Yoder immediately returned to the paddock to retrieve the Barbasol can he had accidentally dropped when he was in the enclosure, thinking that Rexy would be too distracted with the freshly killed Parasaur carcass. But just as he was about to pick it up, his nervous movements caught the Tyrannosaurus's attention. At that very moment, Yoder then attempted to be nice, and tried to sweet talk his way out of being eaten. Realizing this wouldn't work, he grabbed the embryos and ran. When Rexy was just about to kill him, Nima shut the door to the Maintenance Tunnels in the large dinosaur's face.

Sometime later, Rexy confronted the group one last time during the conflict between Nima and Billy. She stalked into the shipping yard, forcing all four of the humans to freeze in their positions. The T. rex started to sniff at Jess when her father gently nudged the cryocan with his foot, causing it to roll toward the dock’s edge. In a momentary lapse of judgment, Yoder scrambled to save the can before it fell into the water. Although he had saved the can, he had caught the attention of Rexy, who growls behind Yoder. Rexy only hesitated for a brief moment before she engulfed the man with her jaws and lifted him in the air to consume him, causing Yoder to drop the can. With the T. rex's back turned to them and Nima racing to retrieve the can, the Hardings followed closely behind. Rexy was alerted by the movement behind her and chased after them. Nima and Jess squeezed into shelter while Dr. Harding was left outside.

Dr. Harding then attempted to distract Rexy in order to keep her attention away from the two ladies. The T. rex damaged the bridge platform the pair was standing on, flinging Jess over the edge. Jess managed to keep herself from falling off the bridge together but was dangling mere feet from the T. rex. She pleaded for Nima’s help and was saved from the jaws of the predator at the expense of the cryocan that was crushed under Rexy's foot. Dr. Harding, while the dinosaur had turned to face Nima and Jess, grabbed a steel pipe. He swung the pipe against Rexy's leg, successfully gaining her undivided attention and allowing his companions to escape to the last remaining boat at the end of the docks. Dr. Harding scrambled through the container yard with Rexy catching up in pursuit. Dr. Harding eventually found cover inside a cage, although Rexy could not reach the man with her jaws due to the small opening at the end that was suited for caging smaller dinosaurs. Frustrated, she thrashed about and finally flung the cage toward the pier that the small boat was located.

Dr. Harding noticed that he was less than a one hundred meters from salvation and scrambled to his feet in which he then sprints for the boat that his daughter was pull-starting. Rexy crashed through the gate that separated the pier from the container yard and started to pursue Dr. Harding while nipping at his heels. As he neared the end of the dock, Dr. Harding jumped onto the moving boat as Rexy made one last attempt to grab him in her jaws. The boat successfully swept its three passengers away from the enraged Tyrannosaurus, who angrily roared at the group and watched as they escaped the island.

Jurassic World

Since after the fall of Jurassic Park, Rexy became the queen of the island for many years until she was finally captured and placed into a new paddock called T. rex Kingdom for the new theme park Jurassic World. There, Rexy became part of an attraction in which she was trained to associate signal flares with prey items, so as to lure her to feed in front of the visitors inside a log-like viewing area for safety and a good view. Visitors can also choose to view her in an upper seating area at the top of the arena.

During the 2015 Isla Nublar Incident, Claire Dearing commanded Lowery Cruthers to open the doors to the paddock after her nephew Gray Mitchell suggested that they needed another combatant in the final battle against the rogue Indominus rex. Once Rexy comes out, Claire leads her to the Indominus using a flare, and the two battle each other. Rexy, at first, gains the upper hand, but the Indominus quicky overpowers her and throws her to the ground. Just as she is about to kill her, Blue quickly sprints onto the screen, scratching and biting her back. This allows Rexy to get back up and resumes battling the Indominus, smashing her into several buildings. She then headbuttts her near the Jurassic World Lagoon, where Mosy, the overgrown Mosasaurus, resides. Before the I. rex can fight back, she is suddenly grabbed by Mosy, who drags to her into the bottom of the lagoon and kills her there, saving the park. Rexy spares Blue for saving her and the two go their separate ways. Later, Rexy walks onto the helicopter base, observes the destruction of the now ruined, abandoned park and unleashes a victory roar, claiming the island as hers once again.

Jurassic World: Camp Cretaceous

Season 2

Since after the downfall of Jurassic World, Rexy was encountered by members of Camp Cretaceous (consisting of Sammy Gutierrez, Kenji Kon, Darius Bowman, Brooklynn and Yasmina Fadoula) while she was hunting a Parasaurolophus. She successfully killed the herbivore and dragged it off to feed. It is then revealed that she had built a nest made out of trees, rocks, and animal bones (including the Spinosaurus skeleton that she destroyed) in T. rex Kingdom which, along with Main Street, she claimed as her entire territory. After an encounter with Sammy Guiterez, Rexy nearly killed Kenji Kon and Darius Bowman, but was distracted by a voice recording and cardboard cutout of Brooklynn.

Later, Mitch and Tiffany were led by Sammy and Darius to Main Street where Rexy attacked the two, getting tased repeatedly on the face by the hunters before they retreated, after which she broke free of the building she had unintentionally gotten stuck in. Rexy then turned her attention to the kids and chased them until Brooklynn used an Innovation Center hologram of a Tyrannosaurus to distract her. However, Rexy realized it was a trick and wandered off. The T. rex was seen chasing after a herd of dinosaurs, attacking a Sinoceratops and the campers. She eventually devoured Mitch, who got caught in his own snare trap and left to his fate by Tiffany.

Season 3

Rexy appears on the dock and attacks a helicopter containing a mercenary, Kenji, Ben and Sammy. Despite Rexy biting the helicopter, the mercenary manages to escape and fly the helicopter. Rexy then kills the mercenary on the dock and chases Darius, Brooklynn and Yasmina. She finds Yaz hiding and starts chasing after her. She almost eats Yaz, but stops when Darius and Brooklynn throw rocks at Rexy to distract her, causing the ferocious carnivore to turn her attention to Darius and Brooklynn and give pursuit. She chases them into some trees and tries to eat them, but after hearing another mercenary, she goes after him.

As shown during the events of Fallen Kingdom, Rexy is seen chasing a mercenary named Jack. After Jack gets on a ladder his team on the helicopter threw down, Rexy grabs the ladder with her jaws and proceeds to drag the Helicopter down with her strength. However, she ends up biting off the bottom of the ladder, which allows the Jack and the other mercenaries to escape, before the Mosasaurus jumps up and eats Jack.

Jurassic World: Fallen Kingdom

Three years after the destruction of Jurassic World, Rexy appears at the former theme park after having sensed a disturbance in her territory. A group of men have entered the lagoon in an attempt to retrieve a DNA sample from the Indominus rex skeleton lying at the bottom. There, Rexy ambushes a worker in a yellow raincoat who is controlling the gate to the exhibit with a remote. As she is chasing him towards a helicopter, she steps on the remote which stops the gate from closing all the way, allowing the Mosasaurus to escape into the ocean.

She then tries to pull the helicopter down by the ladder, but the ladder breaks and she is left holding a piece of it as the chopper flies away. Rexy bellows in anger just as the Mosasaurus leaps from the ocean, devouring the man in the yellow rain coat who is still clinging to what was left of the ladder. The rest of the men get away with the I. rex sample. Rexy appears again when Owen, Claire and Franklin are fleeing from the erupting volcano after being left to die by the mercenaries. The group finds a Gyrosphere but before Owen gets in, a Carnotaurus appears. Just as it is about to lunge at Owen, Rexy lunges and throws the Carnotaurus down, roaring triumphantly as the volcano erupts behind her. She then runs off, fleeing with the rest of the dinosaurs.

After escaping the Gyrosphere underwater, Owen, Claire and Franklin briefly see the T. rex being carried onto the ship along with several other dinosaurs, including Blue. The trio sneak on board as the ship is leaving and locate Blue, who will need a blood transfusion to survive after being shot in a recent confrontation. Claire and Owen sneak into the cage holding the sedated Tyrannosaurus to take her blood, as Rexy is the most similar animal on board to Blue and therefore the safest bet to donate blood. The T. rex is asleep, however she moves her head against Owen making retrieving her blood difficult. Claire has to climb on her back to reach the vein. During the process, some workers notice the door to the Rexy's cage is open, and shuts it, trapping Owen and Claire inside with her.

Moments later, Rexy wakes up and begins thrashing around. Claire manages to slip through the bars on the top of the cage and opens the door to free Owen. The T. rex is still thrashing about, and Owen is trapped. He leaps through Rexy's mouth seconds before her jaws snap shut, and the duo lock her in, leaving her roaring as she tries to escape. Luckily, Claire managed to get the blood out and they are able to save Blue. Later, Owen and Claire are captured, and Rexy is seen being ushered into a holding pen barely big enough for her to stand. She is fed a goat on the way to the basement of the Lockwood mansion where all the dinosaurs are being held in preparation for auction.

Owen unleashes a Stygimoloch to the auction room during the showing of the Indoraptor and Rexy never makes it to auction as she is later presumably still in her cage during the fight with the Indoraptor in the mansion. Later, Claire lets all the dinosaurs out of their cages to free them from the toxic gas. She however refuses to open the doors leading outside, dooming the animals to die with the gas still going off. However, just as it seems that all the dinosaurs will be killed, the doors suddenly begin to open. Maisie explains that she felt compelled to free them because she feels a kinship to them as they are also clones of the extinct ones. The dinosaurs rush to freedom, escaping into the wild. Eli Mills is seen barely dodging the stampede with the Indominus sample and takes refuge under the car, which is quickly trampled and destroyed in the stampede. As Mills gets up from underneath his wrecked car and picks up the I. rex fragment, Rexy suddenly appears and snatches him in her jaws, brutally shredding and tearing him in half along with a Carnotaurus, ultimately devouring Mills at the same time. Rexy then knocks over the Carnotaurus with her head, scaring it off in the process. She triumphantly roars, knowing she is now free again and walks away, destroying the I. rex fragment in the process.

Rexy is then seen breaking into a zoo exhibit and roars at a lion as Ian Malcolm is heard in voice over condoning the serious of events that have lead to dinosaurs being set loose on the mainland.

Jurassic World: Dominion

As revealed in the prologue, Rexy runs off into the night pursued by mercenaries in a helicopter. However they accidentally led her directly to a drive in theater, snapping at the fleeing humans as she roared at them. She then avoided the tranquilizer dart from one of the men in the helicopter and escaped into the forest.


Like any Tyrannosaurus and other theropods, Rexy is portrayed as being animalistic such as behaving like an ordinary Tyrannosaurus who relies solely on her predatory instincts to survive and possesses intelligence comparable to those of ordinary tyrannosaurs. However, she is seen to be curious particularly towards bright flashing lights (flares, flashlights, etc.). Although being already a carnivore, Rexy is understandably bad tempered. At one point, she crushes one of the tour vehicles believing it to be an enemy and later pushes it to the ledge to eliminate those that trespass on her territory. Even though she was born with a genetic defect where her vision is based on movement, Rexy is able to sense potential prey or enemies despite their best efforts to hide and she has seen to be creative in flushing them out.

After the downfall of Jurassic Park, Rexy had been the queen of the island for many years before she was finally captured and placed into a paddock for Jurassic World. Her time in captivity and her advancing age has tempered much of her old behavior, seemingly content feeding on the goats she was provided. When the Indominus rex was unleashed upon Jurassic World, Claire Dearing released Rexy to combat the hybrid, showing to those present including the Indominus rex that she is a force of nature that should not be messed with.

It's heavily implied that Rexy is proved to be very intelligent enough to allow her to be able to be creative as mentioned earlier. Other evidence in the later films show that she is able to cooperate when certain situations arises, such as working together with Blue as a perfect team to end the threat of the Indominus rex. Rexy might have even formed fondness to those that help her. Though harmed by Velociraptors in 1993, Rexy sees Blue is different from her kind and went away thankful, but spares her rather than killing Blue.

Physical Appearance

Rexy is a large 13.5-meter-long (44.3 feet) and 5.2-meter-tall (17 feet) adult female Tyrannosaurus rex with a dull gray and brown color scheme with degradation color zone running down her neck, back and tail. In the first film, she appears to be quite robust and muscular, though her appearance in the fourth and fifth films has changed noticeably, with the stripes on her back having become very faint, her skin tightening, the shape of her head morphing with age and her body becoming thinner. However, she somehow regained mass after Jurassic World's downfall, becoming more robust by 2018. Rexy displays scars all over her body, most notably three large gashes running down the right hand side of her neck and face from what she received during a fight with two Velociraptors in 1993, making her easily recognizable.

Powers and Abilities


  • Tyrannosaurus rex Physiology: Rexy possesses incredible feats of strength, durability, endurance, speed, senses and intelligence, even for a Tyrannosaurus as she is possibly more powerful than any others seen in the franchise.
    • Enhanced Strength: Rexy's primary power is her enormous strength, partly because of her larger size while she also has extremely powerful jaws, making her one of the most powerful predators on Isla Nublar. Her colossal strength allows her to smash through a fallen tree, take out two Velociraptors relatively easily, push large steel cargo crates, smash through a Spinosaurus skeleton and even fend off the Indominus rex for a brief period of time, while also strong enough to ram the hybrid into several objects, including buildings. In Jurassic World: Fallen Kingdom, she briefly halted a Bell UH-1 Iroquois helicopter by biting down on the ladder, easily took down a Carnotaurus, knocked over another one with a head swipe and even walked through a California zoo fence.
    • Enhanced Durability: Rexy's bodily tissues provide her much greater resistance to physical injury as she survived with deep slashes on her neck which would harden into scars after killing two Velociraptors in 1993, revealing that she has a tough hide under which there is a layer of thick fat and muscles. In Jurassic World, Rexy is capable of withstanding deadly swipes and bites from the Indominus rex as well as being slammed to the ground, though she was still injured by the hybrid's attacks. In Jurassic World: Fallen Kingdom, she was even tasered several times by mercenaries pushing her into the elevator to take her down to a cage.
    • Enhanced Endurance: Rexy's endurance is shown to be high as she is capable of enduring attacks from Velociraptors and the Indominus rex.
    • Enhanced Speed: Rexy is capable of moving at great speed as she was able to keep up with a jeep and managed to quickly catch up to a herd of Gallimimus.
    • Enhanced Stamina: Rexy's musculature is considerably efficient. Her virtually inexhaustible stamina enables her to exert herself at peak capacity for an undefined period of time without tiring at all, never needing to slow down when she is hunting her prey. Even during her battle with the Indominus rex, Rexy does not even seem to have any obvious signs of fatigue.
    • Enhanced Senses: Rexy is able to pick up the scent of any human or dinosaur a mile away twice as strong as a modern dog.
    • Enhanced Bite: Rexy has a particularly strong and powerful bite, either because of her sharp teeth, jaw-muscles, unusual jaw-structure or some other reason. Exactly what she can bite depends on the jaw-strength, resilience of her teeth/bite-surface and her shape.
    • Enhanced Intelligence: Rexy is remarkably intelligent as she made sure that the electric fence was deactivated by touching it before escaping her paddock. After the fall of Jurassic Park in 1993 and later Jurassic World in 2015, she was intelligent enough to know how to survive in the wild. She even understood that Blue had saved and joined her in the fight against the Indominus rex.
    • Predatory Instincts: Rexy possesses extraordinary predatory instincts for hunting all things such as dinosaurs, animals and humans. She can track anything under any conditions, sense the weaknesses of her prey and exploit them before finally succeeding in killing them.
    • Binocular Vision: Rexy's eyesight is comparable to modern birds of prey, allowing her to perceive a single three-dimensional image of her surroundings and see perfectly fine in the dark.
    • Master Hunter: Rexy is a master of hunting, using her senses of smell to find and hunt down her prey. As a hunter, she is skilled in tracking and determining what sort of prey she is following and how best to take it down easily.
    • Stealth: Rexy is able to simply blend in so that she can't be seen and will have to wait until her prey is close enough to her.


  • Expert Combatant: Rexy is great at combat against the dinosaurs of Isla Nublar that tried to attack her, as she has fought and killed Velociraptors, a Triceratops, a Carnotaurus, and a Baryonyx. She was even able to battle against the Indominus rex with assistance from Blue, eventually forcing the hybrid dinosaur near the Jurassic World Lagoon, leading to her death at the jaws of the Mosasaurus.
  • Expert Tracker: Rexy is capable of tracking things, determining what sort of prey she is following.


  • Small Arms: Like all members of her kind, Rexy has shorter arms, meaning she is unable to use them to grab her prey, reach down or even fight against opponents.
  • Poor Vision: Due to the defect on her cloning process, Rexy's vision is based on movement, unlike the superb eyesight of the real life Tyrannosaurus. This could possibly be a side effect of the Tyrannosaurus genetic code being repaired with frog DNA.
  • Bright Lights: Rexy can be distracted by bright lights such as flares.


  • Her nickname "Rexy" has become a popular name for her among fans, including Colin Trevorrow, the director of Jurassic World and Jurassic World: Dominion.
  • The roaring and growling of Rexy were made from animal vocalizations such as baby elephants, alligators and tigers.
  • Rexy also appears as a cameo in another Steven Spielberg movie, Ready Player One. She acts as a challenge on the racetrack near the beginning of the movie, attacking drivers alongside various obstacles and King Kong.
