Tyrannosaurus rex (Isla Nublar)

The Tyrannosaurus rex of the film version of Jurassic Park, nicknamed Roberta in the Phil Tippett's storyboards for the Jurassic Park (film)}first film, is a Tyrannosaurus female that appears in , , and. She is know for partipating in several incidents on Isla Nublar and for saving the major human participants involved in these incidents from other dangerous creatures, albeit indirectly.

Creation
As suggested on JurassicWorld.com, Rexy was born approximately in late 1989 or early 1990 inside the InGen Compound of Isla Sorna where she spent a few months of her life inside the lab being taken care of by its workers before being transported to Isla Nublar to live in the Tyrannosaur Paddock as an attraction for InGen's Jurassic Park. JurassicWorld.com's map of Isla Nublar states that her paddock was designed to house a juvenile of her species to live with her, 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

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. 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.

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. 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. 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. 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.

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

Jurassic World
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.

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.

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.

Isla Nublar Incident (2015)
"We need more teeth!"

- Gray Mitchell to Claire Dearing as the Indominus rex overpowers the Velociraptor pack, prompting her to release Rexy.

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 after being able to claw her viciously with its huge arms, the tables were quickly turned, with Rexy thrown down against the Jurassic Traders Outpost, destroying it in the process and almost killing Owen Grady and Gray and Zach Mitchell. 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.

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.

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.
