"Oh, Indominus wasn't bred. She was designed. She will be fifty feet long when fully grown. Bigger than the T. rex."
Henry Wu(src)

The Indominus rex was an hybrid dinosaur and the secondary antagonist of the Jurassic Park franchise. She was one of the largest existing theropods in the Jurassic World film, as well as the film's main antagonist, the posthumous overarching antagonist of Jurassic World: Fallen Kingdom, and one of the two overarching antagonists (alongside Henry Wu) of the Netflix series Jurassic World: Camp Cretaceous (specifically the central antagonist of Season 1 and a posthumous antagonist of the subsequent seasons). 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,[5] Carnotaurus, Giganotosaurus, Majungasaurus, Rugops,[1] Pycnonemosaurus, Quilmesaurus, Viavenator,[11] Deinosuchus,[4] and Therizinosaurus.[2] There were also the DNA of modern animals such as cuttlefish, tree frog,[5] and a pit viper snake.[2]

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. Including the shape of the head in some parts from Giganotosaurus. Abelisaur genes (Carnotaurus, Majungasaurus, Rugops,[1] 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.



InGen's chief scientist, Dr. Henry Wu, was fascinated with the possibility to create entirely new species by gene mixing, ever since he learned that the inclusion of frog DNA had given the dinosaurs the ability to switch gender.[12] On May 21, 1997, he created Karacosis wutansis, a hybrid plant.[13] On April 5, 2009, another hybrid was created.[14]


Indominus rex on the Hammond Creation Lab computer.

Years after opening, Jurassic World's success was lower in 2011 unlike the previous years of its operation.[15] 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.[16] The result was a genetically modified hybrid of several dinosaur genera and modern animals. Development of the hybrid began in 2012[17] in the Hammond Creation Lab[1] 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.[5] Upon Simon Masrani's announcement of the creation of the genetic hybrid, now named Indominus rex, online ticket sales for Jurassic World skyrocketed.[18]

Jurassic World Incident[]

"I would have a word with your people in that lab. That thing out there, that's no dinosaur."
Owen quietly telling Masrani(src)

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.[5] He had not been able to do so for many months due to him being needed for several meeting and events.[19] At the time of his visit, the lone Indominus was not fully grown[5] and was only 12.2 meters (40 ft).[1] 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.[5]

Hybrid predator escapes

Claw marks.

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 car outside of her paddock and then cut the car's fuel line, masking his scent. The Indominus rex then headed off toward the Jurassic World park, attracted by the thermal signatures of the visitors there.[5]

Sneaky indominus

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.[20]

Indominus Rex Jaws

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.[5]

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.[21]


Indominus inside the Jurassic World Aviary.

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.[5][22]

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.[5]

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.[5]

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, avenging the victims she had killed.[5]


"There she is."
Sub Pilot(src)

A short while after the official closing of Jurassic World and the death of the Indominus, the campers from Camp Cretaceous (left abandoned on Isla Nublar due to not arriving at the ferry in time)[23] discovered the remains of the Main Street, the fight that previously took place before, and the corpse of the Indominus in the lagoon. Darius and Brooklynn agreed in relief that they wouldn’t have to worry about it anymore (or the Mosasaurus being hungry with the Indominus’ remains keeping it fed).[24]

Indominus Rex Remains

What remains of the Indominus rex

Even long after its death, the skeleton of the Indominus remained at the bottom of the abandoned park's lagoon. Eventually, a group of mercenaries in a submarine sneak into the lagoon to extract a sample from the Indominus remains. After carving out a rib bone, it is sent to the surface and extracted by a helicopter before the submarine encountered the thought to be dead Mosasaurus.[10]

It's most likely that the rest of the skeleton of the Indominus rex was destroyed with the larger part of Isla Nublar when the volcano Mount Sibo erupted.

The DNA of Indominus, stored in a glass container, was then claimed by Eli Mills. He then assisted Henry Wu in using the Indominus rex DNA to create a new hybrid: the Indoraptor. In the end, the Indoraptor gets impaled on an Agujaceratops skull in the Lockwood Manor and Mills tries to run away with the DNA sample of the Indominus to make new hybrids. However, the T. rex of Isla Nublar eats Eli and stomps on her deceased rival's rib, which ultimately prevents its use in any further creation of new hybrids.[10]


The Indominus rex left a legacy on the campers, they found the remains of the battle of main street realizing the Tyrannosaurus fought the Indominus and that the Mosasaurus had recently eaten it.[24] Afterwards being part of their nightmares after they escape Isla Nublar.[25] In season 4, Yasmina experiences a trauma induced nightmare involving her being surrounded by the Indominus rex, Toro, a Ceratosaurus, and the Scorpios rex.[26] Darius mentions the Indominus when talking about his time on Isla Nublar to Kash D. Langford.[27]

Later, Eli Mills referenced how Claire Dearing had exploited the Indominus rex for profit when Claire called him out for similar behavior with the Indoraptor. Eventually, Rexy crushed the rib of Indominus.[10]

The hybrid could run up to speeds of 30 mph when confined in its paddock with its roar alone reaching 140db-160db, as loud as the liftoff and landing of a Boeing 747 airplane. Indominus rex had spiky osteoderms across its body and horns above its eye orbits, traits that originated from the DNA of various abelisaurs used in its creation.[1] Its osteoderms were extremely tough, being able to withstand fire from a GE M134 Minigun and even an indirect hit from an AT4 rocket launcher.[5] It also had well-developed forelimbs from Therizinosaurus complete with opposable thumbs whose origins are unknown. [2] and had sickle-shaped claws on each of its four fingers with the claw of the middle finger being the longest. Its long arms also made it semi-quadrupedal. It displayed immense physical strength, able to easily slaughter a Brachiosaurus and even bend steel girders.[20] It was able to change color from the cuttlefish used in its creation, which was used as camouflage in hunting, but also helped the hybrid grow at a quick rate.[5] The Indominus rex also had what appeared to be protofeathers growing out of several parts of its body, namely its head and forelimbs. Their base skin color was a grayish white, with eyes whose sclera were a fiery dark orange brown color.

The teeth of Indominus were from Deinosuchus DNA,[4] explaining why the teeth are exposed like a crocodile. Due to this bit of instability, its teeth varied in size, often jutting out at unnatural angles and many were broken. Indominus rex had a total of 74 teeth.[28] Like all other theropods, as well as nearly all sharks, the Indominus constantly replaces its teeth.[5] Another trait that came from Tyrannosaurus being in its gene pool was the massively strong bite force it had,[2] which Indominus could use to even crush a bulletproof Gyrosphere or break the neck of an Ankylosaurus.[5] The Indominus' mandible (lower jaw) was slightly longer than the maxilla (upper jaw), which gave it something of an underbite. One of the most unsettleing features of the Indominus was its ability to unhinge its jaw, shown when it attempted to devour the gyrosphere with Zach and Gray Mitchell.

Its large size is attributed to Giganotosaurus.[2] Interestingly, I. rex could reach 50 ft as an adult[5] when none of the theropods, including Giganotosaurus, used in its creation could reach this length. The cause of this surpassed length in the hybrid is unknown.

The tree frog DNA, which was intended to help them adapt to the climate of Isla Nublar, had allowed it to remove its own thermal signature.[5] The hybrid could also detect the thermal signatures of others as well due to the pit adder DNA.[2] The snake DNA may also be the reason why it could open its jaws wider than any of InGen's cloned theropods. Finally, the DNA from Velociraptor used in Indominus creation gave it a high level of intelligence as well as the ability to communicate with Velociraptor individuals. Good examples of its intelligence being one's plan of making the people that observed her in her paddock think that she had escaped and her ability to remember when and where her creators inserted her tracking implant.[5]

Though they do hunt for food, one known I. rex was shown to kill mainly for sport. This individual also was known to have committed cannibalism, as she killed and ate her own sibling, which was the first thing she did as soon as she hatched.[5] However, since the I. rex who had exhibited these traits had a rough upbringing these behaviors may not be natural.[29] The cannibalism could have came from either Majungasaurus DNA or T. rex DNA or both since both theropods have fossil evidence of cannibalism, though the rough upbringing suggests that it could be a mental illness of some sort seen in this individual.


The Indominus rex is known to display a solitary hunting behavior, although the precise timing of its sibling cannibalization in relation to its movement into a larger enclosure or its behavior upon entering the enclosure alone remains uncertain.

The Indominus rex has exhibited a tendency to kill dinosaurs without consuming them, suggesting that it may engage in predatory activities for reasons other than sustenance, potentially for sport.

There is limited information regarding the encounter between the Indominus rex and Toro, the Carnotaurus, and the exact motivation behind Toro's actions remains unknown.

The Indominus rex has demonstrated its ability to employ strategic tactics, such as luring potential prey, including humans, into specific areas for hunting or elimination purposes. It has also displayed a level of intelligence by deceiving humans into believing it had escaped its enclosure and removing its tracker to avoid detection. Additionally, its camouflage capabilities allow it to blend into its surroundings by altering the color of its skin to a greenish hue, providing an advantage in ambushing and surprising its adversaries.

When the Indominus rex first encountered the pack of Velociraptors, it established a communication with them due to having their DNA in its genetic makeup. It managed to persuade the Velociraptors to become part of its new pack, with the Indominus rex assuming the role of their alpha. Under its command, the Velociraptors were directed to attack the humans.

However, a beta member of the Velociraptor pack named Blue made the decision to remain loyal to her original alpha, Owen. This act of betrayal by Blue led the Indominus rex to retaliate, resulting in an aggressive encounter where the Indominus rex attacked Blue, rendering her unconscious. In response, Blue's other sisters retaliated against the Indominus rex, seeking revenge and protecting Owen. This sequence of events caused the Indominus rex to become extremely enraged.

Indominus Rex (456)

Indominus maquette.

Jurassic World director Colin Trevorrow said that it was this new dinosaur that gave him a reason to tell another Jurassic Park story.[30] In one script of Jurassic World, Indominus was to be a fictional species of dinosaur discovered in China, but Colin disagreed with this idea.[31]

This hybrid had gone through many changes in appearance during the development of Jurassic World. The director of Jurassic World, Colin Trevorrow, has said that it was difficult to design "because we needed it to feel grounded in genetic attributes of animals on our planet right now.".[32] The first design was created by Legacy Effects as a digital sculpture. Aaron McBride and his team at ILM then further designed the Indominus with the aim to create a fictional dinosaur that still appeared grounded in the natural world.[33] One early design by Aaron McBride[34] was similar to the one seen in the film, but had a more triangular antorbital fenestra like that seen in members of Carcharodontosauridae (the family that Giganotosaurus, one of the dinosaurs used in Indominus's creation, is a member of), more quills, had only three fingers, lacked osteoderms and horns, and had a small sail located on its neck like that seen in some restorations of Acrocanthosaurus.[35] In the storyboard by David Lowery, the Indominus resembles McBride's design with its arms somewhat shorter.[36] One early design that displays these traits featured it with a skull that resembled Abelisaurus with osteoderms the size of a large theropod like Tyrannosaurus or Giganotosaurus with arms that were more therizinosaur than the final version. This conceptual design had another variant that was used in pre-production size chart of animals that were (or were planned) for the film in which it was dark gray and visibly taller than T. rex.[37] A toy prototype also resembles Abelisaurus like the previously mentioned concept art, but was more slender with arms like a Velociraptor and a set of fangs on the front of each of its jaws.

For guidance, ILM sought the advice of veteran paleontological advisor of the series Jack Horner.[33] One of Horner's suggestions was Therizinosaurus because of its large arms and claws, which Horner says ILM used as a reference when designing the hybrid.[38] Glen McIntosh also had many discussions with Horner and McIntosh's input was incorporated in the developing design of the hybrid.[33] Industrial Light and Magic's Kris Costa created the original maquette of the I. rex from artwork by Legacy Effects, which served as the template for the digital model.[39] Glen McIntosh was notably concerned about how the mouth configuration of the Indominus would be, so he created several concepts that he presented to Trevorrow featuring three different choices: fully enclosed teeth like komodo dragons and the raptors, half-exposed teeth like the T. rex, and finally exposed, interlocking teeth like a saltwater crocodile, the latter which was chosen. Trevorrow wanted McIntosh to pursue the exposed teeth design and McIntosh created several concepts in response.[33] McIntosh also created descriptive illustrations and sketches to emphasize its osteoderms and defined several of its skull fenestrations, particularly the antorbital fenestra and the infratemporal fenestra.[39]

The conceptual design by Seth Engstrom depicts it with a carcharodontosaurid head with iguana-like spikes running down its back. Several of the concepts by Engstrom depict it as having shorter hand digits with long therizinosaurid claws unlike the final version.[40] Colin Trevorrow liked this trait, and thus it was implemented in the final design of the Indominus.[39] ILM further gave the hybrid its signature underbite to contribute towards giving it a menacing look.[39][41] There exists three concept art pieces that showcase its underbite and are close to the hybrid's finalized appearance. The first has a more triangular antorbital fenestra like that seen in carcharodontosaurids with thick quills on its arms and lacks horns and quills on its head. Furthermore, its color scheme is a mixture of yellow and tan instead of a grayish-white.[41] The second known design depicts it with a wider skull and without quills and thumbs. Finally, there is a design that is near identical to the one seen in the film yet lacks horns, quils, and thumbs with a row of spikes in place of the horns and quills. At some point the design of the eye color and eye shape of the final Indominus was based on a goshawk.[41] The Indominus was later given horns by the designers to differentiate it from the T. rex.[33]

Steve Jubinville was in charge of creating the CGI model of the Indominus, modifying the maquette created by Kris Costa to fit the needs of director Colin Trevorrow. Jubinville created a reference library of his own consisting of lizards, birds, and other animals when designing the dinosaur hybrid. Martin Murphy created the scale pattern of the Indominus using the software MARI by The Foundry and worked with Jubinville in designing the 3D model. The two worked back in forth with each other in ZBrush, Adobe Photoshop, and MARI to complete the computer generated model of the Indominus rex.[42][39] The creation of the CG model of the Indominus rex has gotten Jubinville, Murphy, Aaron Grey, and Kevin Reuter nominated for the 14th Annual VES Awards in the category of "Outstanding Models in a Photoreal or Animated Project".[43] For the hatchling, Matt Corcoran simply resculpted the model of the adult while Jubinville created its eggshell. When creating the hatchling, the aim was to make it "creepy" instead of "cute".[42][39]

The concept of Indominus is very similar to that of the toy line Jurassic Park: Chaos Effect, or, more specifically, the Ultimasaurus, a toy from the toy line. The Ultimasaurus was a hybrid between Ankylosaurus, Stegosaurus, Triceratops, Tyrannosaurus rex, and Velociraptor. The adult form of this hybrid was never released, but a hatchling was included with the Roland Tembo action figure of the toy line. The Indominus rex itself also resembles an unidentified theropod that appeared in the first issue of the IDW comic series Jurassic Park: Dangerous Games. Many fans have noted that the Indominus rex is similar to the Baryonyx Rudy from the film Ice Age 3: Dawn of the Dinosaurs or the fictional Vastatosaurus rex from the 2005 remake of King Kong. Because many people were disappointed with the design of I. rex, they created the #buildabetterfaketheropod project to make their own hybrid theropods.

The name of Indominus rex also changed throughout its design process as well. In the Jurassic World storyboard by David Lowery, the Indominus is referred to as "Malasaurus" and "Malusaurus".[36] Another name for Indominus rex was "Diabolus rex"[44] or "D. rex",[39][45][46] which was a nickname that ILM used for the hybrid before it was given a final name.[47] When Diabolus rex is entered into the "Query" of the Masrani backdoor, the console will reply with an error message saying "Did you mean Axis Boulder?"[48] But if Axis Boulder is entered it will say it is an unknown command. Axis Boulder in itself is an anagram of Diabolus rex.

In David Lowery's storyboards for Jurassic World, the dinosaur hybrid behaves differently. After killing the Ankylosaurus, it is shown to eat the Ankylosaurus, suggesting that the Indominus did not kill it out of sport or defense, but to possibly satisfy its hunger. Another divergence from the film was that it joined the raptor pack—all four of them in the pursuit of Claire and the Mitchells in their vehicle.

According to concept art for Jurassic World, the famous fight between Rexy and the raptors was to occur in some kind of enclosure near a volcano in the rain instead of Main Street and there was one less raptor involved. There was also supposed to be an animatronic Tyrannosaurus coming out of a waterfall, which the hybrids bites, a reference to the scene in the Jurassic Park chapter "Tyrannosaur" and The Lost World: Jurassic Park. The scene where the I. rex bites the head off of the animatronic was cut when the script was being written, due to Steven Spielberg pointing out that the audience might have interpreted the scene as saying CGI is much better than animatronics.[50] The location was later changed to Main Street and in concept art for the fight in the previously mentioned location, it was shown to be raining like the previous concept art and even had pterosaurs flying the background. LEGO Jurassic World's adaptation of the fight seems to be partially based on the latter concept art as Dimorphodons present in Main Street when the battle occurs. In a storyboard for the fight, two raptors were still alive and none of them helped Rexy when she was overpowered by the I. rex. Instead, the I. rex continued to combat the T. rex until she threw Rexy through a concrete wall close the Jurassic World Lagoon where the Mosasaurus kills the hybrid just as she prepares to give the killing blow to Rexy with her sharp claws.[51]

Two early concepts of the Indominus were created by Ian Joyner when the film was in the early stages of production. In one version, the Indominus was depicted as being a large gray theropod with a small, humped back, a pair of two long claws on each of its hands, and a large crest on its snout; while in another, it was going to resemble a yellow Giganotosaurus with dark colored stripes on its body, and linings on its head. This version also sported quill-like feathers along its spine and under its arms.

The roars of Indominus were made from the vocalizations from many different animals. To give the hybrid's vocal mass, vocalizations from walruses, whales, beluga whales, lions, pigs, monkeys (such as macaques), dolphins, fennec foxes, and wild boar. The sound designers for Jurassic World did not use sound effects that were similar to the Tyrannosaurus from the films to differentiate the Indominus from the famous theropod and wanted it to sound irritable to the viewers to make them dislike the hybrid.[52] In trailer releases for Jurassic World, Indominus's roars were reused from Tyrannosaurus rather the roars heard in the actual film.

The demise of the Indominus rex in Jurassic World is similar to that of the Giganotosaurus from the comic series Jurassic Park: Redemption. In the fifth issue of the comic when the Giganotosaurus is quarreling with the main characters at the Texas Nuclear Power Plant, a pack of Velociraptors enter the area and attack the large theropod. While the Giga is overwhelmed with the raptors, it stumbles into the river nearby where it is then killed by a mosasaur that was present in that river since the second issue.

Its camouflage ability resembles the Carnotaurus from the novel The Lost World who shared the same ability. Coincidentally, Carnotaurus DNA was used in the creation of Indominus, but for the pair of horns on its' head, not the camouflage.

The Indominus figure included with the Jurassic World Blu-Ray gift set.

For Jurassic World: The Exhibition, the Indominus animatronic was created by the Australian-based company the Creature Technology Company as with all the other dinosaurs featured.[53]

Much like T. rex, though often referred to as "I-Rex", this is incorrect. Scientifically, it should be referred to as "I. rex", as "rex" is the scientific name for the species.

The limited edition Jurassic World Blu-Ray gift set came with a model of Indominus rex as well as a model of a Tyrannosaurus.

The Giganotosaurus from the video game ARK: Survival Evolved bears a resemblance to the Indominus rex.

In Jurassic World: The Ride, the Indominus escapes her paddock and later attempts to attack the boat tour. She can be seen trying to communicate with Blue before the park's Tyrannosaurus arrives to challenge for territory. In one of the ride's queue videos[54], Dr. Wu states that the Indominus is 21 feet high and over 55 feet long. When asked what happened to her sibling, Dr. Wu admits that she ate it.

Some of the Indominus rex’s sounds were reused for the Skullcrawlers from Kong: Skull Island.

According to Jack Ewins, the originally planned hatching date of the Indominus rex for the Masrani Backdoor website was going to be 2009, but it was changed to 2012 after advisement from Colin Trevorrow.[55]
