"We have a T. rex."
John Hammond(src)

Rexy, also known as Rexie,[2] is the female Tyrannosaurus rex that appeared in the first Jurassic Park novel, the film adaptation of the same name, a video game sequel and Jurassic World, as well as many issues of the Topps comics.

This creature is never called by a given name (like Bakhita or Lady Margaret). However, Robert Muldoon nicknames her "Rexy" on multiple occasions in the first novel.[3][4] This is similar to how the Big One, a Velociraptor, is also based on a nickname and not a given name in the franchise. She might have also gotten this nickname from Billy Yoder, but under a different spelling ("Okay, we can't go back outside because of our old friend Rexie").[2]



As suggested on, Rexy was born approximately in late 1989 or early 1990[1] inside the InGen Compound[5] of Isla Sorna[6][5] where she spent a few months of her life inside the lab being taken care of by its workers[6] before being transported to Isla Nublar to live in the Tyrannosaur Paddock as an attraction for InGen's Jurassic Park.[7]'s map of Isla Nublar states that her paddock was designed to house a juvenile of her species to live with her,[8] but it is unknown if a juvenile was ever transported to the paddock.

Isla Nublar Incident (1993)

"Boy, do I hate being right all the time."
Ian Malcolm(src)

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 and Tim Murphy took a tour of the Park, the Tyrannosaurus was initially a no-show. Although computer technician Ray Arnold attempted to lure her to her paddock fence by tantalizing her with a goat, however, Rexy still refused to answer the call. Dr. Alan Grant, observing this, surmised that it was because she wanted to hunt her prey rather than have it offered to her.[7]


Rexy roars as she becomes free from her paddock.

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 programming, the tour vehicles that the tour group was shut down in front of the paddock with its electrified fencing in the same state as well. At this point, Rexy revealed herself to the visitors by eating 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 on a toilet to hide. By that point, the Tyrannosaurus rex moved to the disabled fencing and ripped the fencing apart with her teeth; she proceeded to step through her mangled handy work and roar triumphantly. After a minute or two of exploring and investigating the Explorers, her attention was aroused by the light that was emitted from a flashlight Lex had activated in the front Explorer. Unaware that the source of the light was inside the car, she walked right to the front door and peered out into the jungle in front of the SUV. It was not until Tim slammed the open door next to the 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 interesting objects inside, she set to attacking the mysterious vehicle in front of her, searching for a way to get at Lex and Tim to eat them. After failing to get at them through the vehicle's skylight, Rexy flipped the car over and proceeded to savage the undercarriage whilst crushing it under her massive foot. Thanks to the efforts of Dr. Grant and Dr. Malcolm, the T. rex was briefly distracted. Rexy followed Dr. Malcolm as he fled toward the Tyrannosaur Paddock Bathroom, where she injured him by flinging the mathematician into the air just as her head came crashing through the door, causing Malcolm to be buried in the wreckage. The destruction of the building revealed the cowering Gennaro, who Rexy proceeded to devour while Dr. Grant rescued the kids inside the car. Before long, however, Rexy returned and pushed the vehicle over the cliff while Tim was still inside and pushing Lex and Dr. Grant off the edge with the car, though the three survived and slept in a tree for the night after they got out of the car.[7]

As park game warden Robert Muldoon and Dr. Sattler were in the Tyrannosaurus Paddock investigating the whereabouts of the survivors and had found Dr. Malcolm, she attacked the search party. Muldoon and Sattler had heard the T. rex roar several times before during the search and just before her ambush Malcolm heard Rexy's footsteps. The T. rex attacked suddenly, without warning, crashing through a line of trees where she began chasing them through a tree lined corridor. After a very close chase, she was unsuccessful in catching them, and so she finally gave up, letting the trio escape to the visitor center.[7]


Rexy killing a Gallimus as Dr. Grant and the Murphys watch.

The next day, during Grant’s, Tim’s, and Lex’s continued trek to the Visitors' Center, they found themselves in the Gallimimus Enclosure, and witnessed a stampeding herd of Gallimimus. They ran alongside the dinosaurs momentarily before hiding behind a fallen log. Rexy suddenly crashed through the nearby bushes next to the stampede stumbling a Gallimimus. This Gallimimus tried to run away, but was too slow to react, and the Tyrannosaur lunged at it, catching the dinosaur in her jaws before proceeding to shake the Gallimimus to death. Dr. Grant, Lex and Tim watched in amazement as the T. rex started to feast on the carcass. 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.[7] Rexy never fully consumed this Gallimimus and its remains were still present in the location where it had died by October 6, 2002, over a decade later.[9]


Rexy roaring after killing the raptors inside the Visitor Center.

Rexy was seen later that day when she had come through the hole in the wall and grabbed a Raptor from mid-air just as it was to pounce on the humans and crushed it in her jaws. Using the distraction that Rexy provided, the humans fled. Meanwhile, another raptor that pursued the group through the Visitors Center pounced on the larger theropod. Rexy snapped at her but could not reach her as the raptor continued to rip and tear madly. Rolling her head, the Raptor fell into the T. rex's mouth where she was killed and then thrown against the Tyrannosaurus skeleton and Rexy let out a mighty bellow in triumph as the "When Dinosaurs Ruled the Earth" sign fell to the ground.[7]

In the aftermath of the incident, Rexy went wild and lived on Isla Nublar for about a decade,[1][10] probably surviving off any of the herbivorous dinosaurs that managed to survive the incident.

Jurassic World

Rexy Jurassic World

Rexy living in the T. rex Kingdom.

According to the Masrani backdoor, during the construction of Jurassic World, Vic Hoskins and his team of InGen Security Division troopers encountered Rexy on April 19, 2002.[11]

Sometime later or in the encounter with InGen Security, Rexy was captured and put back into captivity where she lived in the T. rex Kingdom attraction of the dinosaur park.[1][10]

She was still fed goats like before, but to bring her out, a flare would be thrown to get her attention. She served as one of the most popular attractions, particularly at feeding time.[12]

Isla Nublar Incident (2015)

"We need more teeth!"

Indominus VS T. rex

Rexy faces off with an Indominus rex in Main Street.

Rexy mainly stayed in her paddock for most of the incident, until she became involved when Claire Dearing told Lowery Cruthers to open her enclosure's door after Claire's nephew Gray Mitchell told her that there needed to be another dinosaur to help kill Indominus rex during the final battle of the incident. Using flares, Claire guided Rexy to the Indominus rex where she threw the flare at the hybrid. When the flare hit the I. rex, Rexy attacked her viciously.

Initially Rexy had the advantage, landing several bites to the I. rex's neck, but the hybrid soon became the dominant opponent in the conflict, putting the Tyrannosaurus to the ground, particularly on the Jurassic Traders Outpost, destroying it in the process and almost killing Owen Grady and Gray and Zach Mitchell.[12]

Jurassic World Rexy 2

Rexy roaring after the 2015 Isla Nublar Incident

However, before the Indominus could kill her, Blue, the surviving Velociraptor of the battle, intervened by lunging onto the I. rex, giving Rexy time to get up off the ground. With Blue latched onto the hybrid Rexy grabbed the Indominus dragging her into the nearby buildings of Main Street. At one point, Blue rode on Rexy's back while she smashed the I. rex into one of the buildings. She finally flung the hybrid near the edge of the Jurassic World Lagoon where the Mosasaurus that resided there leaped out of the water to snatch the I. rex and drag it underwater, drowning the hybrid. After the fight, Rexy and Blue looked at each other, but Rexy decided to spare Blue, thanking the raptor for her help with a small nod before walking away, wild once more.[12]

In the aftermath of the incident, Rexy let out a triumphant roar from the Control Center helipad while overlooking the ruined park that had become void of any people, claiming the island as hers once again.[12]

Jurassic World: Fallen Kingdom

Rexy is confirmed to return for the sequel, Jurassic World: Fallen Kingdom. A couple of leak photos revealed that she will be captured again, and likely be transported off the island. There would also be scenes where she would be portrayed via animatronic for the first time since the first film.

At some point during the destruction of the island by the eruption of Mt Sibo, Owen and his group encounters Rexy again, who had just saved them from a Carnotaurus as they were about to escape in a gyrosphere.

Some times later on, Owen and Claire find her in a truck, where Owen says "This is gonna be awesome", and looks into Rexy's eye, for her eye to open.



Attack on Lady Margaret

T-Rex vs Trike JP Telltale

Rexy fighting the Triceratops Lady Margaret.

Sometime during the night of the tropical storm, after escaping her paddock, 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 the 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 Rexy. The group barely managed to escape, hiding in a maintenance shed as the dinosaurs fought and decided to spend the night inside.[13] It is unknown what was the outcome of this fight, but it is known that Rexy survived and that Lady Margaret lost a horn.[14]

Return to the Visitor Center


Rexy chasing Jess up the Visitor Center stairs.

After killing the raptors in the Visitor Center, she briefly left said center but returned when Dr. Gerry Harding, Jess, and Nima Cruz reached the Visitors Center, unaware that Hammond and the surviving members of InGen's endorsement team had had just recently fled 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.[15] 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 Rexy's attention, Gerry dropped a box that hit her back. Jess grabbed the tranquilizer darts and ran upstairs to help Gerry where they healed Nima. The T. rex proceeded to follow Jess up the stairs, but at the last second, the staircase collapsed, causing the T. rex to wipe out, struggling to get back up. When the Tyrannosaur regained balance the vibration of her feet caused Jess Harding to fall while the Trio was escaped just outside on the roof.[16]

T-Rex Jess

Jess dangling from the door frame of the Visitor Center with Rexy just below her.

Even though Jess caught a ledge preventing her falling to her death, 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. Rexy then tried to kill Jessica as she dangled from the door frame. As Dr. Harding grabbed his tranquilizer gun, Jessica finally lost balance and landed on the top of the head of the T. rex, which prompted Rexy to shake Jess off her head. Dr. Harding soon fended off the Tyrannosaurus using his tranquilizer, saving Jess from potentially being eaten. However, Rexy's retaliation was quick and she soon charged through the door frame, destroying it. She then proceed to attack the tour vehicle that the Hardings were behind using as shelter. Rexy's attack on the Harding finally came to an end when Dr. Harding told Dr. Sorkin to start the tour vehicle, which distracted the T. rex.[16]

Helicopter Encounter


Rexy chasing the mercenaries' helicopter as it takes off.

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 the mercenary Danny Cafaro had disappeared. Rexy reappeared and made her way towards them, forcing 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, she nudged it, causing the aircraft to swerve, but Yoder ultimately piloted the helicopter to safety and evaded the T. rex.[17]

Encounter with Nima and Billy

Then, after Jess helped Dr. Sorkin in the Parasaurolophus Enclosure, Nima got into a fight with Billy Yoder, who was sitting in a tree, Rexy appeared again, chasing a Parasaurolophus, and then Yoder almost fell but grabbed a branch in order to save himself. Rexy, having noticed this, picked up a piece of helicopter wreckage with her mouth, 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.[18] Then he and Nima began to run away from the T. rex and she followed them into the Parasaur Paddock. Inside, Rexy became distracted with a Parasaurolophus carcass and briefly during the feeding killed a Velociraptor that had been eating the carcass as well.[19] Yoder immediately returned to the paddock to retrieve the Barbasol can he had 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 Rexy's attention. At that very moment, Yoder then attempted to be nice, and he tried to talk to her. Then he grabbed the embryos and ran. When the Tyrannosaurus was just about to grab him, Nima shut the door to the Maintenance Tunnels in the large predator's face.[20]

Final Encounter


Rexy killing Billy Yoder.

She confronted the group one last time during the conflict between the Nima and Billy. Rexy stalked into the shipping yard forcing all four of the humans to freeze in their positions. Rexy 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 the large theropod. Rexy only hesitated a moment before she engulfed the man with her jaws and lifted him in the air to consume him. Yoder dropped the can. With the T. rex's back turned to them, Nima raced 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.[21]

Dr. Harding then attempted to distract Rexy in order to keep its attention away from the two ladies. The T. rex damaged the bridge platform the pair was standing on flinging Jess over the edge. She managed to keep herself from falling off the bridge together but was dangling mere feet from Rexy. She pleaded for Nima’s help and was saved from the jaws of the predator at the expense of the cryocan that was crushed by the approaching Tyrannosaurus. Dr. Harding, while Rexy had turned to face Nima and Jess, grabbed a steel pipe. He swung the pipe into the leg of the Tyrannosaurus, successfully gaining her undivided attention, thus allowing his companions to escape to the last remaining boat at the end of the docks. Dr. Harding scrambled through the container yard, the large theropod hot on his heels. Dr. Harding eventually found cover inside an animal cage. Rexy could not reach the man with her jaws due to the small opening at the end that was suited for caging smaller, man-sized dinosaurs. Frustrated, the animal thrashed about and finally flung the cage toward the pier that the small boat was located.[21]


Rexy watching the survivors escape on the boat.

Dr. Harding noticed that he was less than a one hundred meters from salvation, he scrambled to his feet and sprinted for the boat that his daughter was pull-starting. Rexy stalked through the gate that separated the pier from the container yard. The animal was nipping at Dr. Harding for the final stretch As he neared the end of the dock, he jumped onto the moving boat as the carnivore made one last effort to grab him. The boat successfully swept its three passengers away from the angered animal that bellowed loudly after its prey.[21]


Jp novel Euroclub 91 2

Rexy on the cover of the novel.


Rexy was created inside the laboratory of a village owned by InGen on Isla Sorna for their amusement park/zoo Jurassic Park on the neighboring island Isla Nublar.[22] A Version 4.1 Tyrannosaurus,[23][24][25] she was shipped to the park to live in the attraction known as Carnivore Country 2 sometime before 1989. Despite being female, the park's staff would refer to her as a male.[26] Later, or possibly simultaneously, a juvenile was shipped to her enclosure to live with her, but would keep its distance from Rexy.[23] During Rexy's time in the enclosure, she and the juvenile would sometimes get sick from drinking the water of the enclosure for an unknown reason.[27] Rexy would also gaze at the nearby Sauropod Paddock interested in the Apatosaurus living there.[28]

InGen Incident

"You know, at times like this one feels, well, perhaps extinct animals should be left extinct. Don't you have that feeling now?"
Ian Malcolm to Alan Grant after Rexy's attack on Land Cruiser BB4.(src)

The endorsement witnessed Rexy being fed a goat during their tour of Jurassic Park. Because many of the members were leaning out of their car windows during the spectacle, Robert Muldoon, the park's game warden, became concerned for their safety so he decided to retrieve the park's only rocket launcher.[28]

When Dennis Nedry disabled Jurassic Park's power, Rexy was able to escape her enclosure. After the juvenile escaped, she too did the same. Using her hind limb, she tore down the depowered electric fence. Once free, she decided to attack the Land Cruiser of Tim and Lex Murphy, BB4. The Tyrannosaurus thrashed the car several times, severely damaging the vehicle and injuring its passengers before she finally lifted BB4 into the air where it became caught in a tree. She then proceeded to sniff the ground. While she did this, Dr. Ian Malcolm, who witnessed the attack with Dr. Alan Grant inside Land Cruiser BB5, decided to leave the vehicle and make a desperate run to safety, which was in the Tyrannosaurus' direction.[29] Rexy noticed him and tossed him away violently,[29] with the fall breaking his leg.[30] Afterward, Rexy also noticed Dr. Grant leaving his car as well, but unlike Malcolm, Dr. Grant stood still, preventing Rexy from seeing him. But the Tyrannosaur indirectly attacked him unknowingly when she kicked the land cruiser over.[29] Though they were injured from the attack, all the people that Rexy harmed survived the attack.

At some point, Rexy tore through the fence of the Sauropod Paddock and entered it,[31] presumably due to her interest in the paddock's sauropods. Inside the paddock, she hunted a herd of Hadrosaurus killing one in the process,[32] Dr. Alan Grant and the Murphy children witnessed this hunt.[32] She then took one of the Hadrosaurus she killed and traveled to the dock near the Raft Storage Maintenance Building where she fell asleep.[33]

Dr. Grant and the Murphys encountered the adult Tyrannosaurus while trying to retrieve a raft to reach the human populated areas of Isla Nublar. They managed to retrieve one of the rafts in storage and became waterborne without waking her. However, not too long after getting onto the water, Lex Murphy started to cough, which awoke the sleeping T. rex. Now awake, Rexy proceed to pursue the boat and attack the three. During the conflict, Dr. Grant tried to stop her by firing the air pistol at her, to no effect. Ultimately, Rexy did not kill the humans despite being close to doing so as she heard the juvenile Tyrannosaurus nearby with an Apatosaurus it had killed and instead chased the younger member of her species instead.[33]

She did not catch the juvenile, probably because it evaded her or Rexy became uninterested in the younger Tyrannosaur. The adult Tyrannosaurus then traveled to the Jungle River Cruise.[34]

The Tyrannosaurus encountered Dr. Grant and the Murphys once again while on the bank of the Jungle River and tried to attack them several times, but was unsuccessful each time due to the thick foliage restraining her. Unsuccessful in her attacks, the Tyrannosaurus continued to travel down bank where she harassed a mating pair of Dilophosaurus, which allowed the humans to safely bypass the venomous dinosaurs.[34]

The Tyrannosaur continued to explore the Jungle River Cruise and as she did, Robert Muldoon and Donald Gennaro were waiting to tranquilize her and return her to her paddock. Muldoon fired his shot at Rexy only to miss. This angered the Tyrannosaurus and she proceed to charge toward the two men's jeep. As she ran towards them Muldoon fired a second shot, which did hit its target, but because the tranquilizer's effects did not reactive fast enough Gennaro believed he had missed. After the second shot was fired, the two men quickly returned to the Visitor Center to evade the angered Tyrannosaur.[4]

Just after the Muldoon and Gennaro left, Rexy encountered Grant and the Murphy children for a fourth time as their raft fell down the nearby waterfall that contained Maintenance Building 04. Rexy attacked them again, but only caught Lex's life jacket and the humans went inside the waterfall while she was distracted with the vest. Later, when Alan Grant was inside one of the maintenance building's interior, Rexy poked her head inside the waterfall. She used her tongue to feel around the room for any of them humans. She found Tim and began to pull him towards her mouth, but while doing so the effects of the tranquilizer kicked in, rendering her unconscious.[4]

Jurassic Park's staff was supposed to retrieve her after they had discovered she was successfully unconscious, but the park ran out of auxiliary power just after the discovery.[35]

Both tyrannosaurs and the raptors killed many of Jurassic Park's fauna, creating an equilibrium in Isla Nublar's dinosaur population.[25]

If she did not drown in the pool of water made by the waterfall, Rexy was certainly killed along with the rest of the cloned fauna on Isla Nublar in the Costa Rica Napalm Bombing that followed after the InGen Incident.[36]

LEGO Jurassic World

Rexy appears in LEGO Jurassic World as a playable dinosaur. Like the other dinosaurs in the game, Rexy sometimes participates in humorous antics, such as scratching Blue's head at the end of the game due to the game's comical nature.

Jurassic World

The figures of T. rex in this toy line are based on Rexy in the Jurassic World film.

LEGO Jurassic World

The LEGO set T. rex Tracker T. rex was based on Rexy from Jurassic World. It includes a T. rex, Vic Hoskins, an ACU solider, and a Vet.

Behind the scenes

see Jurassic Park Tyrannosaurus rex Animatronics

Despite the novel stating that both of the Tyrannosaurus rex have reddish-brown skin[28] the Euroclub 1991 and Dutch covers of the Jurassic Park novel depict her with dark green skin. Furthermore, both covers gave her extra fingers, instead of the two fingers that T. rex has, with the Euroclub cover giving her three and the Dutch cover giving her a full five fingers like a human. Rexy is also green in concept art for the Jurassic Park film.

Grant on River

The raft attack concept art for the Jurassic Park film.

Like in the novel, Rexy was supposed to die in the Jurassic Park film, but this was changed.[37]

Rexy's animatronic in Jurassic Park would occasionally malfunction in the rain.

Rexy is by far the most popular Tyrannosaurus in the franchise. After she had a fight with the Indominus, and won, fans gave her many nicknames, such as "Queen Rexy" or "Queen of Isla Nublar".

The scene where Rexy attacks Dr. Grant and the Murphy kids' raft in "Tyrannosaur" of the Jurassic Park novel was originally going to appear in the film as concept art exists, but it was cut. Another scene from that chapter where Rexy pokes her head inside the waterfall and licks Tim Murphy was adapted into a scene in The Lost World: Jurassic Park with the Tyrannosaur Doe and the humans fleeing from her committing the same actions like the characters in the chapter.

The original ending to Jurassic Park did not feature Rexy's involvement at all. The Velociraptor pack would have been killed by the two mounted skeletons inside the Visitor Center, one being impaled by a rib of one of the skeleton as it collapsed and the other by Dr. Grant taking control of a crane where he moved the second raptor into the jaws of the T. rex skeleton where it would become crushed by its jaws.[38][39] Another scrapped ending was that only one of the raptors was to be killed by one of the skeletons falling on it while the remaining raptor was shot by John Hammond.[40] Director Steven Spielberg scrapped these endings because he realized that Tyrannosaurus rex was one of the stars of the film only rivaled by Velociraptor.[38] This ending was further prompted by the success Industrial Light and Magic had from the CGI model of Rexy.[39]


Rexy crashing through the Spinosaur skeleton.

A Jurassic World sight gag is shown where Rexy destroyed the Main Street's Spinosaurus skeleton to kill the Indominus, referencing the fight in Jurassic Park III where a Spinosaur killed a T. rex and the scene's backlash. Colin Trevorrow probably added this scene in the film to apologize to T. rex lovers, even though he didn't direct or even work on Jurassic Park III.

In Jurassic World, Rexy sounds like the Tyrannosaur Buck from The Lost World: Jurassic Park instead of her sounds from Jurassic Park. It's likely this is the case because the filmmakers wanted Rexy to sound older, as she lived from the 1993 Isla Nublar Incident, which was 22 years ago. However, her original roar from Jurassic Park did not go unused. She issued her original call twice during her battle with the Indominus.[citation needed]
