Indominus rex was a biological product of International Genetic Technologies, Inc. produced on Isla Nublar in 2012. Only one would survive, with the other being cannibalized by its sibling at some point before November 2014. Details about the life of the cannibalized sibling are mostly unknown, but the survivor’s life history is fairly well documented.
Masrani Global Corporation officially had intended to create new genera of theropod in order to counteract the stagnating revenues at Jurassic World. InGen Security, led at the time by former American security contractor Vic Hoskins, also intended to use it to test the concept of military bioengineering. With financial backing from Lockwood Foundation manager Eli Mills, the Indominus rex genome was constructed by Dr. Henry Wu utilizing multiple theropod gene donors as well as genetic traits from several extant animal species. The exact content of its genome was shrouded in secrecy; differing personnel were informed about differing aspects of the animal, resulting in corporate mismanagement that allowed the hybrid to escape containment in 2015. Despite the secrecy, the project had US $26,000,000 invested in it.
Name
Neither Indominus is known to have been given any form of name or designation, and were most likely identified solely by specimen numbers. As only one survived, distinguishing between the two is not necessary in most cases. It is usually identified simply using its genus or species name.
Biography
Early life
Both Indominus hatched within the same day at some point during 2012 on Isla Nublar. This followed roughly four years of experimentation after their creation was authorized on April 4, 2008 by Masrani Global Corporation CEO Simon Masrani and Jurassic World’s Senior Assets Manager Claire Dearing. The Jurassic World website states that this species originated in the Hammond Creation Laboratory, but while the genetic research may have gone on here, it is more likely that they hatched in the field genetics lab since this was off-limits to the public. Henry Wu had previously utilized this laboratory for a series of experiments concluding with E750, the direct predecessor to Indominus. After hatching, each one was fitted with a subdermal RFID tracking implant which would constantly update the Jurassic World computer network with the dinosaurs’ locations and biometrics. The implants were placed in the animals’ backs, just above the left shoulder in at least one of them. The Indominus were intended to live in a paddock with physical walls and therefore would not have been affected by the park’s invisible fencing system, but unlike other animals where this was the case, the Indominus tracking implants were programmed to shock them if they came too close to other park attractions. This was presumably an additional security measure.
At an unknown point prior to November 2014, one of the Indominus cannibalized the other. This information was not relayed to Simon Masrani, who had not yet seen the animals in person.
Life in isolation
The surviving Indominus was maintained in Paddock 11, located in northwestern Isla Nublar far into Sector 5 where park visitors were not permitted. Animal handlers would regularly provide her with the food she needed to survive, but she had little other contact with the world outside the paddock.
She was planned to eventually be displayed in her own paddock within the park area, which would have showcased her in an arena for guests to view. This attraction was planned to open in May of 2015, but this date was delayed until June for safety reasons. She grew more quickly than anticipated, and attempted to tear the arm off of a paddock worker at feeding time; these concerns resulted in changes to her containment procedures. The walls of the paddock were built higher, and feeding was performed using a crane to lower steer carcasses into the habitat.
Simon Masrani officially revealed the existence of the Indominus rex on his corporate blog on January of 2015, having hinted at it since November. Ticket sales to Jurassic World skyrocketed at the revelation, but the life of the Indominus remained the same; there was no way that she could have understood that she would be moved to an exhibit at some point in the future, nor would this do anything to alleviate her lack of stimulation. The opening of her exhibit was delayed until early January 2016, likely due to the same security concerns as before.
Over time, she learned to utilize chromatophores in her skin to camouflage against her environment. She also discovered that she could mask her heat signature by modulating her thermal output until it was indistinguishable from background heat; she likely discovered this ability because she was capable of seeing infrared.
Sometime before December 2015, an incident occurred in which she attempted to break the observation window of Paddock 11. She was able to crack the glass, but did not succeed in breaking through to the other side of the barrier.
2015 incident and death
On December 22, 2015, Verizon Wireless Vice President Hal Osterly and two representatives visited Isla Nublar to meet with Dearing and Dr. Wu. After being given an informative description of the Indominus, Osterly agreed to sponsor the animal and her exhibit.
Simon Masrani would finally come to visit his hybrid dinosaur on the same day, three or four years after she was created and three weeks before she was due to be put on exhibit. He was impressed with the results, but expressed concerns about safety similar to those expressed by Jurassic World staff. He tasked animal behaviorist Owen Grady with surveying the paddock due to Grady’s experience with intelligent animals in captive conditions.
While Dearing was bringing Grady to the paddock, the Indominus (now around forty feet in length, ten feet shorter than her projected adult size) appears to have made an escape attempt. Claw marks were found on the paddock wall leading nearly all the way up. After scaling the wall but not actually escaping, she camouflaged herself within the paddock and decreased her infrared output as to appear invisible. This led to the thermal scanning technology failing to locate her, suggesting that this was the first time she had used this ability to such an extent.
Dearing immediately assumed the worst and made for the park’s control room while Grady took the paddock supervisor and one of the workers inside the paddock to assess it, as this would be the only way to quickly learn about the highly classified animal. The Indominus, still within the paddock, did not immediately take action, instead remaining hidden. Grady and the two other staff members were alerted to its presence from the Control Room after technician Lowery Cruthers located the Indominus using its tracking implant, discovering that it had never escaped. The three personnel within the paddock panicked, fleeing for the door to the observation room; at this point the Indominus took action and blocked their escape. The paddock supervisor, who had spotted the animal first and run the opposite direction, opened the paddock’s dinosaur gate in order to escape. The Indominus and two remaining humans all made for the gate; one worker was grabbed by the Indominus and was killed. The gate was shut remotely, but the dinosaur pursued Grady out of the paddock before they could completely close. She was able to overpower the mechanical force closing the gate, breaking it and escaping. While she located and killed the paddock supervisor, she was unable to locate Grady as he hid underneath a sun-heated vehicle and doused himself in gasoline. She moved into the surrounding jungle after failing to detect him.
Grady theorized that the claw marks on the wall of Paddock 11 were an intentional distraction meant to trick park staff into entering the paddock under false pretenses, but this would suggest the dinosaur had a far greater understanding of human psychology and park operational protocols than is reasonable. A more likely alternative explanation is that the claw marks were from a genuine failed escape attempt, and that the ensuing incident was due to simple mismanagement on the part of staff members involved.
As she strayed outside of her designated zone, her tracking implant delivered an electric shock intended to dissuade her from venturing too far. However, the lengthy arms and dexterous clawed fingers of the Indominus permitted her to dig into the flesh of her left shoulder where the device was located and remove it. With this irritant gone, she traveled south toward the border between Sectors 5 and 4, possibly due to the density of heat signatures in the central part of the island.
Shortly after removing her tracking implant, she encountered an ACU squad which had been sent to recapture her. She camouflaged herself to ambush them, killing leader Katashi Hamada and several other personnel. This fatal incident resulted in a Real World scenario being issued for the park, closing down attractions and concentrating visitors in Sector 3.
With the remaining Security personnel dealing with the Real World protocols, the Indominus was relatively unhindered and took a detour northward again. She encountered Facility 4, perhaps honing in on the sounds of the Troodon Jeanie who inhabited the place. After eyeing and then smashing a security camera above the building’s wall, she rammed through a weak point in the infrastructure to attack whoever was inside. The humans there were forced to retreat, and while Jeanie was trapped by a broken hot water return pipe, the Indominus could not reach her due to her bulk being restricted by the remaining wall. She pulled herself out, leaving the facility behind to venture farther into Isla Nublar.
Along the way she encountered a Brachiosaurus, killing the titanic creature by ambush. Two park rangers were present trying to rescue the members of Camp Cretaceous; she camouflaged, charged the rangers, and swallowed them both whole. She attacked and destroyed the Camp Cretaceous observation tower, then proceeded to the campsite. Here she skirmished with the rangers again, attacking and killing several and destroying the campsite elevator; this caused the treetop cabins to collapse.
She continued south, encountering the Carnotaurus paddock and its inhabitant Toro, who challenged her with a territorial roar that she returned. Their encounter is mostly unknown, but she attacked the fence, which was then destroyed from inside by Toro once it was weakened.
She broke into the central valley at some point and slaughtered six Apatosaurus in the Gallimimus Valley apparently for enjoyment; she was not seen to feed from any of her dinosaur victims that day. Despite these sauropods’ enormous bulk and physical strength, they had never encountered predators before, let alone one that could camouflage itself; they all died due to shock and blood loss. The Indominus then reentered Sector 5 by breaking through a gate in the border wall. She used camouflage to stalk a small group of Ankylosaurus, managing to kill one while also inadvertently disabling a gyrosphere which had been driven illegally into the Sector 5 ankylosaur habitat. The gyrosphere, which contained Zach and Gray Mitchell, was subsequently destroyed; she pursued the boys to a small waterfall, but gave up pursuing them after they hid underwater for several seconds.
At some point, she engaged in another conflict with ACU, killing several personnel.
She returned to the site of the ankylosaur fight, chasing after a van driven by the Camp Cretaceous campers toward the field research lab. A surviving scientist, who had apparently witnessed attacks on ACU and other staff earlier, tried to flee in the van; she attacked the fan and killed him, then pursued the campers through the lab’s container yard before they escaped again. Sometime after this, she broke into a small restricted area in Sector 4 containing the remains of the Jurassic Park Visitors’ Centre where she killed a Timack Construction worker.
Later that day, she was drawn back to the remains of the Visitors’ Centre. She was most likely drawn there by the sound of an old Jeep being started up by the Mitchells in an attempt to cross the island more quickly; the sound also drew Grady and Dearing to the Centre, as they were searching for the missing boys. The Indominus attempted to reach Grady and Dearing, who escaped through the building due to their smaller size. At that point, Simon Masrani had volunteered to personally fly ACU troopers to gun down the hybrid in the Eurocopter JW001, which distracted the Indominus from its latest victims.
JW001 pursued the Indominus across the island’s central valley, which by this point was no longer filled with tourists. She attempted to remain under cover, eventually sighting the Jurassic World Aviary and breaking into it in order to escape heavy gunfire. Inside, she was immediately surrounded by surprised pterosaurs; she attempted to attack the Pteranodons, which fled out through the hole in the transparent polymer wall. While she made more passes at the panicking reptiles, several of them caused damage to JW001 that resulted in it plummeting through the Aviary roof. Sparks ignited its fuel and caused a large explosion, frightening the Indominus and the remaining pterosaurs out of the Aviary.
The Indominus retreated to Sector 5 after this incident, remaining somewhere north of the raptor research arena. Due to the death of Simon Masrani, Hoskins and InGen Security took control of the situation and appropriated the raptor response team to track the escaped hybrid after nightfall. Grady, accompanied by his friend and coworker Barry Sembène, led an InGen Security team into the forest while the raptors tracked the Indominus via scent.
When the hybrid became aware of the raptors’ presence, it gave a vocalization which they unexpectedly recognized. Velociraptor Echo responded to the Indominus, leading to a cautious interaction between the lone hybrid and four raptors. This, notably, would be the first and only positive relationship the Indominus had with another living creature. The raptors, having grown old enough to challenge Grady’s authority, considered the possibility of freedom that the Indominus represented. The humans suspected that the raptors could turn aggressive, and at an order from Hoskins, InGen Security personnel opened fire on the Indominus. She and the raptors fled into the surrounding jungle, narrowly avoiding heavy gunfire and an AT4 rocket launcher strike. She hid while the raptors picked off the threatening InGen Security personnel, calling the raptors back to her once the firefight died down. One of the raptors, Charlie, had perished during the conflict.
Shortly after the last boat from the NMS Centre left the island, the Indominus tore through the monorail track leading from the Centre to Ferry Landing.
The raptors reached Sector 3 and the Samsung Innovation Center ahead of the Indominus, on Main Street just across the Lagoon from where all the tourists were waiting in the hotel complex for evacuation. The raptors had killed Hoskins by this point and cornered Grady, Dearing, and the Mitchells. With these four humans as just a step on the way toward the hotel complex, the Indominus encouraged the raptors to make the kill. Delta and Echo looked to Blue for guidance, however, and Blue’s familial relationship with Grady caused her to defy the Indominus. Unable to accept any challenge to her authority, the Indominus lashed out in an attempt to kill Blue. This invoked the wrath of Delta and Echo, who launched a retaliatory attack. Grady used his rifle to provide assistance, but the hybrid’s thick osteoderms meant that this was ineffective.
Her superior size and strength allowed the Indominus to overcome and kill both remaining raptors, an with that obstacle out of the way, she cornered Grady and the Mitchells inside the Jurassic Traders booth. While she entertained herself attempting to extract the now-helpless humans, she was interrupted by the arrival of the park’s aging female Tyrannosaurus, which Dearing had released in a desperate attempt to save the others. This was the first enemy the Indominus encountered which had actual experience living in the wild, and so was a more formidable opponent; even so, her long and powerful arms gave her an edge, and she overpowered this dinosaur just as the others.
While she prepared to deliver a killing bite, she was distracted by a bark from Blue, who had survived the initial attack and recovered. The Indominus, shocked, did not react in time to stop Blue from landing on her head and delivering an attack with tooth and claw. While she attempted to get the raptor off, the tyrannosaur found a second wind and launched a new attack as well. Unable to focus on either opponent long enough to cause any damage, and with numerous injuries sustained as the tyrannosaur became wise to her combat strategies, she was forced back toward the edge of the Lagoon. The disturbance attracted the attention of the park’s resident Mosasaurus, which gripped the Indominus and dragged her by the neck to the bottom of the Lagoon. The Indominus was killed and partially eaten.
Legacy
While the Indominus died less than a day after its escape into Isla Nublar and never reached adulthood or produced any offspring, its lineage did continue in a sense. Henry Wu’s artificial evolution project continued despite Hoskins’s death and was still financially backed by Eli Mills and the Lockwood fortune. Wu’s specimens, which were removed from the Hammond Creation Laboratory by InGen personnel, were seized by the U.S. government shortly after the incident; this would have included all of his Indominus material. The current location and status of the seized assets are unknown at this time.
Due to the loss of all his specimens (as well as his credentials), Wu needed to obtain new samples to continue developing the hybrid genome. A sample was retrieved in June 2016 from the skeletal remains of the Indominus rex, which were still in the Jurassic World Lagoon; the lower half had been eaten, but enough remained to acquire a viable DNA sample. This sample was used over the next two years to develop a prototype Indoraptor, essentially a scaled-down Indominus with a greater proportion of Velociraptor genetic material. Hoskins had supported the creation of such an animal prior to his death. On June 25, 2018, this sample was destroyed; the original skeleton was likely inaccessible by that point due to increased volcanic activity on Isla Nublar, meaning that the only surviving traces of the Indominus genome were in the seized assets, the Indoraptor remains following the animal’s death, and any smaller samples in Wu’s possession.
The actions of the Indominus also led directly to the closure of Jurassic World, though this was chiefly spurred on by the heavily-publicized pterosaur attack on Main Street. The death of CEO Simon Masrani, closure of its world-famous theme park, and the loss of Henry Wu as a company asset caused unprecedented financial troubles for Masrani Global Corporation that would impact it for the foreseeable future.
Skills
Camouflage
By December 22, 2015, the surviving Indominus had learned how to use her chromatophore-laden skin to change color. This enabled her to camouflage against her environment, rendering her nearly invisible to other nearby animals. By changing her skin color to camouflage, she was able to ambush victims and hide from danger; her skills were advanced enough to fool human eyes.
As her younger sibling (the only other member of her species) died before much observation could be made, the survivor’s camouflage skill level as compared to other Indominus is unknown.
Infrared sensing
Both Indominus were capable of infrared sensing, or “heat vision,” allowing them to spot other animals nearby even if they were hidden well. However, this was not infallible, as an animal could hide under a hot object (such as a vehicle left out all day in the tropical sun) and mask its own thermal signal.
Infrared output modulation
In order to better adapt to temperature changes, the Indominus were outfitted with the ability to modulate their thermal output. Due to its ability to see infrared, the surviving Indominus learned to mask its own thermal signal by lowering its body temperature to equal that of the surrounding environment. This made it effectively invisible not only to other heat-sensing animals, but also to the thermal imaging technology used to keep track of its location within Paddock 11.
Problem-solving
InGen scientists believe that the Indominus was intelligent for a dinosaur, though Velociraptor is still generally considered superior in this respect. Nonetheless, the surviving Indominus had well-developed problem-solving skills that allowed her to overcome challenges presented by her environment. While her escape may have been a result of corporate mismanagement rather than a deliberate misdirection plot on the animal’s part, she used her intelligence to evade capture and kill victims throughout the several hours between her escape and death on December 22, 2015.
Communication
The surviving Indominus was capable of rudimentary communication with Velociraptor antirrhopus masranii, due to sharing some of the genetically-coded communication instincts with that animal. The full extent to which they were able to understand one another is unclear, but they were observed to succeed in basic call-and-response, nonviolent contests for leadership, and hunting orders. The Indominus was unable to vocally negotiate when the raptors disobeyed a command, however, and immediately resorted to violence.
She also had limited communication with a Carnotaurus at one point, though this appeared to consist largely of territorial confrontation. Damage to the carnotaur paddock, but not the animal itself, suggest that the conflict was resolved with some degree of cooperation. She similarly mimicked a tyrannosaur’s territorial roar, though this encounter ended much more violently.
Physical strength and durability
The physiology of the Indominus led to immense strength and resilience, enabling one that escaped to survive fairly well in the wild. Her large hooked claws allowed her to attack and defend herself as well as grapple with objects in her environment, and her opposable thumbs and lanky arms gave her an ability to manipulate objects on par with most primates. Due to being very large, she was among the brawniest theropods, capable of holding her own in clashes with almost any animal (excepting the enormous Mosasaurus maximus, so long as the reptile remained in the water). She could even resist human technology, as her thick osteoderms protected her against smaller firearms.
Social skills
The surviving Indominus had very poor social skills, killing and eating her sibling for unknown reasons and slaughtering various animals out of enjoyment. Her only positive relationship with other animals, a group of four Velociraptors, was ended immediately when one of the raptors defied an order. She also had a brief, apparently cooperative relationship with a Carnotaurus, but the nature of this relationship is unknown and appears to have been only temporary. Her behavior has been likened to that of an emotionally-immature human young adult; as she never reached adulthood, it is impossible to tell if she would have become more capable of moderating her interactions with other animals. Her sibling’s social skills remain unknown.
Views
Self-awareness
The surviving Indominus is one of the few InGen animals whose internal thought processes have been studied at all, giving some insight into how she perceived herself. Her escape on December 22, 2015 massively changed her self-identity by allowing her to encounter other animals. Prior to this, her only encounters with other animals had been with her human overseers, her sibling (which she killed and ate), any small creatures such as insects and birds that entered her paddock, and the fodder animals presented to her in an already-dead state. Through her experiences with these other living things, she came to understand herself as a predator, designed to kill; her other abilities were likely discovered by a combination of instinct and experimentation.
Having never encountered any living thing that could substantially threaten her as a young adult, she lacked fear during her escape and perceived herself as a superior predator to the other creatures she encountered outside. This would lead her to discovering other large animals, such as ankylosaurs and sauropods, which presented her with more of a challenge; nonetheless, she was able to overpower these targets and kill them without sustaining much injury. These served to reaffirm her self-perception as the superior force in her world.
Encountering other theropods gave her the chance to really examine what she was physiologically, as opposed to just her relationship to the rest of the world. She first realized she had some similarity to other theropods during an encounter with a Carnotaurus, mimicking its territorial roar and apparently helping it escape containment. The Velociraptors, which shared some forms of communication with her, gave her a sense of self; her mannerisms even changed slightly after she met them, using vocalizations she had not exhibited before and holding her arms higher in a manner similar to the raptors. She could also be heard making a bellowing sound in response to a territorial challenge from a Tyrannosaurus, suggesting that she recognized this aspect of her genetic heritage as well. Despite all of these revelations, she was unable to adapt her behavior to survive during the conflict on Main Street.
Perception of her world
After killing and eating her sibling, the Indominus‘s world was defined by solitude within Paddock 11’s walls attended to by humans. She attempted to lash out at them, viewing them either as enemies or potential prey; this led to a change in her feeding regimen. Instead of being fed by workers through slots in her wall, she was fed from a large crane stationed outside. This crane was the only positive relationship of her youth.
Even with her interactions with humans reduced, she still saw them as enemies. She could be seen glaring at them through the observation window fairly often, and attempted to break the glass at one point. When not trying to intimidate her observers, she would spend time concealed within the foliage, out of view. Eventually, she learned to camouflage, and used her natural abilities to further reduce her visibility. Never provided with stimulation, her only means of entertainment would have been natural objects found inside her paddock and any small animals that happened across her, as well as her human caretakers. Her aggressive outlook on other living things may have been a result of this isolation, leaving her with predatory behavior as her only source of entertainment.
She escaped upon the first opportunity she was presented with, and throughout the several-hours-long incident that ensued, her world continued to grow bigger. Outside, she encountered new living things; nearly all of them were treated as targets. She entertained herself by torturing and killing various animals she discovered, adapting her strategy each time. Based on her actions, InGen animal behaviorist Owen Grady suggested that she viewed herself at the peak of the natural order, superior to the other living things in her environment. This was exemplified by her brief relationship with Jurassic World’s raptor response team; she quickly assumed herself their superior, leading them in her quest toward the resort and its densely-packed crowd of vulnerable humans. When she gave an order to kill Grady, who had raised the raptors from eggs, their alpha Blue refused; the Indominus retaliated by immediately trying to kill Blue. She was unable to accept any kind of resistance to her authority. Her death was even a result of this lack of comprehension; she could subdue one opponent with ease, but when two opponents attacked her simultaneously, she was driven back. The concept of cooperation was beyond her understanding, and was ultimately her downfall.
Relationships
Dr. Henry Wu
As with virtually all of InGen’s dinosaurs, the Indominus would have been designed by revolutionary geneticist Dr. Henry Wu. This animal had a particularly special relationship to the man, being the first animal species to have an artificially synthesized genome. Artificial hybridization in the laboratory had existing precedent; Wu’s de-extinction methods relied upon replacing segments of decayed ancient DNA with compatible genes from modern donors. The creation of Karacosis wutansis in 1997, however, demonstrated that instead of simply altering existing genera, scientists could actually create entirely new genera by using a genome as a template in which to insert functional genes from other species. While Wu considered the Indominus a source of great personal pride, he did not directly interact with her often.
Each other
The relationship between the two Indominus, for the most part, is unknown. Two were produced in the event that one did not survive. At some point between 2012 and November 2014, one of the two died due to being eaten by its sibling.
Jurassic World staff
The surviving Indominus was a source of consternation for her paddock workers. Originally, she would be manually fed, but safety concerns regarding this procedure were brought to Claire Dearing’s attention after a worker’s arm was almost torn off by the animal at feeding time. From that point onward, she was fed via crane. She continued to threaten her paddock’s workers until her December 22, 2015 bid for freedom in which she killed two employees, including her paddock supervisor Nick Letting.
She was most likely maintained by other Jurassic World staff, such as the paleoveterinarians and genetic research personnel, but information about her genetic makeup and physiology was heavily regulated. It is unclear which staff members had access to her; it was likely a need-to-know basis, and simply put, many staff simply did not need to know.
During her travels across the island, she killed at least one construction worker near the old Visitors’ Centre, as well as a scientist named Eddie at the field research genetics lab. It is not clear how many other park employees died due to her activity.
Masrani Global administration
On April 4, 2008 a meeting of the Board of Directors confirmed that a new attraction would be sufficient to save Jurassic World from revenue stagnation. Claire Dearing (Senior Assets Manager 2007-2015) and Simon Masrani (Masrani Global CEO 1992-2015) authorized Dr. Henry Wu to create a new attraction; the only direction he was given was to make a “cool” dinosaur that was unlike any which previously existed. Vic Hoskins (Head of InGen Security 2001-2015), acting independently of the rest of the park’s administration, proposed that Dr. Wu craft this animal with the potential for military use in exchange for his work being funded by generous benefactors. Wu accepted the offer, which resulted in the Indominus being engineered for combat situations.
Neither Dearing nor Masrani had any knowledge of the Indominus‘s genetic makeup or unique physiological traits, as Wu kept this information tightly restricted. The Indominus would escape confinement as a direct result of this lack of communication.
In a bizarre turn of events, the Indominus would end up in direct conflict with both Dearing and Masrani during the December 22, 2015 incident on Isla Nublar. She would pursue Dearing on several occasions as Dearing took to the field with animal behaviorist Owen Grady to retrieve her errant nephews from the park, including an incident in which Dearing authorized a Tyrannosaurus to be released from captivity to provide herself, Grady, and her nephews a means to safely escape from the hybrid. Masrani would take to the skies in his personal helicopter JW001 despite not having a valid pilot’s license and his flying instructor being unavailable to bring two ACU troopers to gun down the animal, which resulted in the Jurassic World Aviary being breached and sealing the park’s fate as well as his own death.
The Indominus would not directly interact with Hoskins at any point.
InGen Security
Two branches of InGen Security would have antagonistic relationships with the Indominus, despite her creation as a military animal having been sanctioned by InGen Security head Vic Hoskins. She would first face the Asset Containment Unit, with two teams led by Austin and Katashi Hamada; they were tasked with recapturing her using nonlethal weapons. They did not succeed in this effort, and most of the team members were killed. She also killed and ate at least two Park Rangers at the Camp Cretaceous site, as well as causing other deaths throughout the day. Two ACU troopers were brought out in JW001 by Masrani Global CEO Simon Masrani, this time armed with lethal weapons; while the hybrid could not reach them, they were both killed along with Masrani himself due to territorial Pteranodons being released from the Aviary.
Several hours later, after nightfall, she would be confronted by InGen Security’s contingency services, armed with much more lethal weaponry; these men, led by Hoskins, utilized the raptor response team in a field test to determine if the raptors were combat-ready. This backfired when the raptors turned on InGen Security, despite Grady and Sembène’s concerns that exactly this kind of scenario was a possibility. The Indominus, therefore, did not need to engage in combat with InGen contingency services at all.
Owen Grady
InGen animal behaviorist and ex-Navy lieutenant Owen Grady, who worked on the I.B.R.I.S. project between 2012 and 2015, was brought by Claire Dearing to inspect the Indominus paddock at the behest of Simon Masrani at the beginning of the 2015 incident on Isla Nublar. When park staff mistakenly believed that the animal had escaped, Grady immediately sought to inspect the paddock from the inside, as he had no other way to gain information about this highly secretive project. Had he waited for authorization from Dearing to do so, the animal would have stayed contained, but his disregard for authority figures worked to the Indominus‘s benefit as she was able to prevent Grady and the paddock workers from escaping back through the door to the observation deck.
Throughout the course of the next few hours, Grady mostly worked with Dearing to attempt to retrieve the Mitchells from the park, but would be antagonized by the Indominus throughout. Following the death of Simon Masrani, he was coerced into actively hunting the hybrid down along with the raptor response team; while Grady was opposed to the operation, Hoskins made it clear that he had no choice in the matter. During the conflict, Grady attempted to shoot the Indominus to assist the raptors in the attack, but this had no effect. Following the failure of the raptors to kill the animal, he mainly attempted to stay out of its way and keep the Mitchells safe.
Park guests
Upon her initial escape, the Indominus picked up the heat signatures of over twenty thousand park guests south of her location and began migrating toward them. She passed through Camp Cretaceous, threatening the six campers during her trek southward; after attacking them at the field research lab, she resumed her journey toward Sector 3. Along the way, she ran across two guests who had ignored the park closure warnings, Zach and Gray Mitchell. She briefly pursued them after breaking them out of a gyrosphere, but they evaded her. She returned to her southward journey despite encounters with InGen Security and eventually reached Main Street, encountering the Mitchells again along with Dearing, Grady, and the surviving raptors. The remaining thousands of guests were crowded into the hotel complex just across the Lagoon; had she not been dragged under by the Mosasaurus following a climactic battle, she likely would have made the final leg of her journey and reached the guests.
Jurassic World animals
Having never seen anything of the outside world, the Indominus had no sense of natural ecology and reacted in a violent and immature manner to other animals she encountered. Many of these animals had never encountered predators before and were ill-prepared for combat. Her victims included at least one Brachiosaurus, six Apatosaurus, and one Ankylosaurus; three other Ankylosaurus had fled from her, and she harassed numerous Pteranodons. The smaller Dimorphodons in the Aviary escaped her notice, but her presence disturbed them nonetheless. Notably, the ankylosaur she killed was the adoptive mother of a juvenile named Bumpy, who she encountered again a few times throughout the incident alongside the Camp Cretaceous members.
A few wild animals, such as scavenging crows and flies, benefited from the carcasses she left behind.
Toro
The Indominus had a mostly-unknown but intriguing relationship with a male Carnotaurus nicknamed Toro. This territorial theropod challenged the Indominus with a loud roar, which the Indominus replied to; the Indominus began pushing on the fence of Toro’s paddock during their confrontation. The roars used by both animals were very similar, establishing that they could understand one another to a limited degree. How they interacted is not known; later, the paddock fence was seen busted out from the inside, and Toro showed no signs of having been attacked. This suggests that the Indominus weakened the fence, then Toro broke out through the damaged section, but the two theropods did not fight one another. While Carnotaurus have fairly normal levels of theropod intelligence, it is possible that the Indominus intentionally damaged the fence as to let Toro loose. While she did not possess empathy and so would not have done this out of compassion, it is possible that she understood that releasing this aggressive dinosaur would hinder the people pursuing her.
Raptor response team
The only real positive relationship the Indominus had was with the raptor response team. Echo responded to her howl, suggesting that some kind of mutual understanding was possible; this provoked the Indominus to come forward. She established a rudimentary form of communication with the raptors using similar vocalizations, causing them to question Owen Grady’s authority; in the resulting confusion, InGen Security fired on the Indominus and the raptors, caught in the crossfire, retaliated against the humans. The Indominus briefly had these raptors as allies, but the eldest raptor Blue refused to attack Grady due to his being a paternal figure to her. Blue challenging the Indominus‘s authority caused the Indominus to lash out, killing Delta and Echo after attempting unsuccessfully to kill Blue. The ensuing fight heavily involved Blue, who attacked the Indominus‘s face while the hybrid was distracted fighting a tyrannosaur.
Of all the four raptors, only the youngest, Charlie, never fought against the Indominus. Charlie was killed in a firefight shortly after rejecting Grady’s authority, but showed signs of questioning this decision.
The Tyrannosaurus
A senescent female Tyrannosaurus dubbed “Rexy” was released by control room technician Lowery Cruthers at the command of Claire Dearing as a last-ditch effort to kill the Indominus before it made its way to the hotel complex. The tyrannosaur was overpowered, but was able to turn the tide when the Indominus was distracted by Blue clawing at her face. The tyrannosaur caused serious injuries to the hybrid while forcing her toward the Jurassic World Lagoon, but stayed back, apparently aware of the Lagoon’s inhabitant.
The Mosasaurus
Alerted to the commotion occurring on Main Street, the park’s Mosasaurus spotted the Indominus on the Boardwalk and breached out of the lagoon to capture her. The Indominus was killed and partially eaten as a result.
The Lockwood Foundation
While the Lockwood Foundation was ostensibly used for charitable purposes, its manager from the early 2010s until 2018 Eli Mills would also use it to fund research into military bioengineering. He was most likely the benefactor behind the Indominus project, working with Vic Hoskins and Henry Wu. The Foundation’s creator, Benjamin Lockwood, was probably unaware that his money was being used to fund the Indominus.
Marine One
Post-mortem, the Indominus was targeted by Marine One, a division of a mercenary team sent to retrive Indominus DNA from the last remaining source not seized by the U.S. government. A section of rib was removed by the submarine’s operators and sent to the surface. The Indominus indirectly led to the deaths of both Marine One team members, due to the intrusion of the Mosasaurus which had not been fed in several months.
Genetic relatives
The Indominus never met the other species in her lineage, but did exist at the same time as her predecessor Scorpios rex, namely the original specimen E750. This misshapen creature was considered a failure by Simon Masrani due to its extreme ugliness, which pushed Wu to develop a hybrid animal to market to the military rather than for entertainment. E750 was in cryonic stasis for several years while the Indominus was created; it did not get out of containment until around a month or two after the Indominus died.
A DNA sample from the Indominus was used as the basis to create the genus Indoraptor. At least one was created directly from this DNA sample, and from a genetic perspective, can be considered the “son” of the Indominus. This prototype had many personality traits in common with the Indominus.
Portrayal
The Indominus is almost entirely portrayed using computer-generated imagery. One of her hands is portrayed in Jurassic World using practical effects for a single scene in which it attempts to grab Gray Mitchell and snags the strap of his pack. Her head, neck, and shoulders are portrayed using animatronics in Jurassic World Live.
At one point, her species name was going to be Diabolus rex (meaning “diabolic king” or “demon/devil king”). Her character design went through several variations, some emphasizing her carcharodontosaurian genetic components. In terms of personality, she was always intended to be extremely aggressive, but storyboards imply that she was going to have the animal-like aspects of her behavior emphasized (for example, actually eating her victims rather than killing purely for the adrenaline rush) or be portrayed as a more tragic creature in the vein of Frankenstein’s monster. Her relationship with the raptors is also toned down from what earlier storyboards imply; overall, the shift in Jurassic World‘s tone toward an action-based militainment genre caused the Indominus to be simplified into a sadistic, brutish killer.
