Indominus Rex's History
Indominus Rex is one of the largest existing theropods in the Jurassic World film, as well as the film's main antagonist, the central antagonist of the first season of the Netflix series, Jurassic World: Camp Cretaceous, and a minor antagonist in the show's fourth season. In the film Jurassic World, she was going to be the latest attraction added to the park for higher profits. The hybrid was created by modifying the genome of a Tyrannosaurus Rex with the DNA of various other theropods. Some of the known species that were included were Velociraptor, Carnotaurus, Giganotosaurus, Scorpios Rex, Majungasaurus, Rugops, Pycnonemosaurus, Quilmesaurus, Viavenator, Deinosuchus, and Therizinosaurus. There were also the DNA of modern animals such as cuttlefish, tree frog, and a pit viper snake.
The genome of Tyrannosaurus Rex was used as the base genome for the hybrid. It also gave the Indominus rex an incredibly strong bite that could crush bulletproof glass. Velociraptor DNA was added for high levels of intelligence and the ability to make plans and decisions. Giganotosaurus DNA was added for the large size of the Indominus. It was mentioned that the Indominus Rex would be larger than the T. Rex when fully grown. Abelisaur genes (Carnotaurus, Majungasaurus, Rugops, Pycnonemosaurus, Quilmesaurus, and Viavenator) were added to act as a biological form of armor that absorbed most of the incoming attacks. Deinosuchus DNA was used to form the crocodilian teeth of the Indominus that were used in grasping the flesh of opponents. Therizinosaurus DNA added the presence of long forelimbs with strong, slashing claws. One swipe of the hybrid's claws would take down a specific opponent. Cuttlefish genes were intended to help the Indominus withstand an accelerated growth, but it also added chromatophore cells in the skin so it could change the shape, color, and texture of its skin like a cuttlefish. Tree frog DNA was added for the Indominus to adapt to the tropical climate of Isla Nublar, but it instead added the ability for the animal to remove her thermal signature, which confused most of the heat-based infrared cameras. Lastly, pit viper snake DNA added special cavities in the skull that allowed her to see infrared, which helped her see the heat coming from her prey in dark areas.
Years after opening, Jurassic World's success was lower in 2011 unlike the previous years of its operation. Simon Masrani attended a meeting on April 4, 2012, in which the board of his company unanimously desired a new attraction for Jurassic World to satisfy investors. After he had gotten out of the meeting, Simon emailed Dr. Henry Wu his approval to create a new species. The result was a genetically modified hybrid of several dinosaur genera and modern animals. Development of the hybrid began in 2012 in the Hammond Creation Lab sometime after the board meeting. Unknown to Masrani was that Dr. Henry Wu, the creator of the hybrid, had made a deal with InGen Security Division commander Vic Hoskins to weaponize it in a grand scheme to have dinosaurs be used in military operations and kept many of the creatures used in its creation a secret. Upon Simon Masrani's announcement of the creation of the genetic hybrid, now named Indominus Rex, online ticket sales for Jurassic World skyrocketed.
Two I. Rex were meant to be kept in their own paddock that had walls with a height of 12 meters (40 feet). This was also planned in case one of them died. However, the older Indominus cannibalized her own sibling and would also attack the workers of her paddock as well. Three weeks before their paddock was open to the public, Simon Masrani visited the paddock. He had not been able to do so for many months due to him being needed for several meeting and events. At the time of his visit, the lone Indominus was not fully grown and was only 12.2 meters (40 ft). Simon told Claire Dearing to consult Owen Grady to see if he was interested in taking a job requiring him to inspect the paddock for any vulnerabilities after seeing her attempt of breaking the glass in the observation deck.
That same day, the Indominus later managed to avoid her temperature being picked up by the thermal cameras thanks to the frog DNA in her species and left claw marks on the walls to make them think she was able to climb over the enclosure's wall. When Owen Grady, paddock supervisor Nicholas Letting and worker Nick Kilgore came in to investigate the damaged paddock, the hybrid ambushed them as soon as they got word that she was still in the paddock, making a quick meal out of Kilgore in the process. As they fled, she managed to break through the door as it was not fully shut. Free at last, the I. Rex managed to detect and eat Letting, but Owen evaded her by hiding under a nearby crane outside of her paddock and then cut the crane's fuel tank, masking his scent. The Indominus Rex then headed off toward the Jurassic World park, attracted by the thermal signatures of the visitors there.
The Indominus then came across a group of campers from Camp Cretaceous. After killing a Brachiosaurus and two employees trying to warn them, the Indominus tried to get Darius Bowman, Brooklynn, Ben Pincus, Kenji Kon, Sammy Gutierrez and Yasmina Fadoula by tearing down the observation deck they were on. However the campers managed to elude her by using a zipline to escape. It then tore apart their campground before coming across a caged Carnotaurus named Toro and used its great strength to tear down the fence, setting him free.
Her escape was not reported to Jurassic World visitors because Simon Masrani thought the Asset Containment Unit would capture her by following her tracker implant. The I. Rex traveled south of her paddock having detected the thermal signatures of the visitors in Main Street. She managed to claw out her tracker, along with some flesh still attached to it, and ambushed the team as soon as they arrived, killing most of the troopers, including Katashi Hamada, Craig, and other members of the team, convincing Owen that the island needed to be evacuated.[5] Owen proceeded to tell the others to use live ammuniton against the hybrid, but Claire refused saying that she didn't want to turn the park into a warzone. An angered Owen left the control room stating to Masrani that he wanted to talk with the scientists that created the Indominus, saying that it is no dinosaur. Claire made the decision to close every attraction north of the resort.
This Indominus might have been responsible for opening one of the Gyrosphere Valley's fences to the Restricted Area of Isla Nublar.
She then found brothers, Zach and Gray Mitchell, who were observing four Ankylosaurus in the island's Restricted Area after traveling through the opened gate and attacked the two. In her attack, one of the Ankylosaurus proceeded to fight back against her (mainly to protect a young Ankylosaurus), though her counterattack ended with her being killed by the Indominus via rolling her onto her back and breaking her neck. She resumed attacking the two brothers by piercing her mid talon into the glass and rotated the vehicle so the boys could see their demise. She then attempted to chomp the Gyrosphere whole but got her mouth stuck. She attempted to smash it several times into the ground to crack it open, but the two brothers escaped by getting out of their damaged Gyrosphere and jumping off a waterfall. She gave out a loud roar in disappointment and headed to the Gyrosphere Valley.
The Indominus soon encountered the kids from Camp Cretaceous again, along with Bumpy, the young Ankylosaurus that the adult died defending, found an abandoned ACU van. Because he had a learner's permit, Kenji was able to drive it. The kids barely escaped from the pursuing hybrid by driving off a cliff and down a steep incline, seeking refuge in a private lab operated by Dr. Wu. Wu's assistant Eddie, who was hiding in the lab, stole the van and abandoned the children, only to be waylaid by Indominus who knocked the van off the road and killed him. After this, the kids found a second van parked nearby and were able to escape in that, despite the I. Rex chasing them.
Shortly afterward, the Indominus attacked a herd of Apatosaurus, killing five and fatally injuring one before moving on into the restricted area of Isla Nublar, leaving their bodies uneaten. While in the restricted area, the I. Rex discovered Owen and Claire inside the Visitor Center to which she took the opportunity to attack and chase them after pretending not to notice them and breaking through the ceiling. However, her pursuit of the humans ended when she saw the JW001 piloted by Masrani outfitted with a heavy machine gun in pursuit of her. She led her pursuer to the Jurassic World Aviary where she smashed through the enclosure's walls and scared the pterosaurs inside out of the aviary to the open hole she created. This was witnessed from afar by both Claire Dearing and Owen Grady as well as the Camp Cretaceous kids, who'd crashed their second van into a boulder. As the freed pterosaurs led to the destruction of JW001 and attacked the guests in Main Street, the Indominus traveled further into the restricted area of the island.
That night in the restricted area the members of Jurassic World's Velociraptor pack found her. However, when she began communicating with the raptors, Owen realized and remarked that the Indominous was part raptor. She became the alpha of their pack. As the leader of the pack, she commanded the raptors that were under her control to attack the humans that came with them and were in the area, to which they followed this order. Upon the initiation of this order, the InGen Security troopers, Owen, and Barry Sembène, who were following the Velociraptors opened fire on the hybrid. She managed to escape the brawl that ensued as the small arms fire had little to no effect on her, but she did nearly collapse on the ground when she was hit by a rocket from one of the troopers while escaping.
The I. Rex finally arrived in Main Street where she met Owen, Claire, the Mitchell brothers, and the three remaining raptors once again, commanding the raptors to finish them off. Owen successfully attempts to regain Blue's trust by removing her camera only seconds before the hybrid's arrival. Blue once again regards Owen as her alpha. Blue screeches at the I. Rex, shortly before it responded by knocking her into a wall, seemingly killing her. The raptors, now aligned with Owen's group again, proceeded to jump on and attack the Indominus while Owen provided extra fire, albeit ineffective fire, with his rifle. But the fight ends fairly quickly after the Indominus easily kills Delta by tossing her into a grill, incinerating her, and snatches and throws Echo away. With the raptors defeated, the Indominus Rex then proceeded to resume hunting Owen and the Mitchell brothers who were huddled inside the Jurassic Traders Outpost, one of Main Street's shops. She nearly dragged Gray to her, but was stopped when Claire threw a flare at her, which then caused her to turn her attention to another dinosaur who challenged her: Jurassic World's veteran Tyrannosaurus Rex.
The T. Rex carried out a heavy assault on Indominus, and the two dinosaurs engaged in a ferocious battle. Though the T. Rex initially dominated the fight, she was eventually brought to the ground by the hybrid's strength, destroying the Jurassic Traders Outpost and almost killing Owen Grady, Gray, and Zach. The Indominus almost delivered the killing blow before she was attacked by Blue who was still alive from the onslaught. This allowed the tyrant to return to her feet and grab the I. Rex by the neck, pushing her into many of Main Street's buildings, all while Blue assisted the Tyrannosaurus. Finally, she was flung to the edge of the Jurassic World Lagoon. The attacks from both the T. Rex and Blue were so heavy that it caused the hybrid to actually bleed and pieces of metal were even sticking out of the left side of her torso. The I. Rex got back up from the ground, however, still ready to fight the theropods once more. While she let out a roar, the lagoon's resident Mosasaurus detected the hybrid and proceeded to emerge out of the water to pull the I. Rex under the water to her death.
