Indominus rex

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

- Dr. Henry Wu

Indominus rex was the latest attraction in Jurassic World. The was created by combining the genetic traits of multiple species. Some of the known species that were used in the creation of the hybrid are Tyrannosaurus rex, Velociraptor, Carnotaurus, Giganotosaurus, Majungasaurus, Rugops, and Therizinosaurus as well as modern animals like cuttlefish, tree frogs, and a pit viper snake. It served as the main antagonist of the film.

Prelude
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. On May 21, 1997, he created Karacosis wutansis, a hybrid plant. On April 5, 2009, another hybrid was created. 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.

Characteristics
"The base genome is a T. rex, the rest is classified."

- Claire about the creation DNA of Indominus

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 across its body and horns above its eye orbits, traits that originated from the DNA of various abelisaurs used in its creation. 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. It also had well-developed forelimbs from Therizinosaurus complete with opposable thumbs whose origins are unknown 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 allowed it to become semi-quadrupedal. A single swipe of its claws was able to incapacitate, and several were able to kill even giant sauropods like Apatosaurus. 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. Their base skin color was a grayish white with eyes whose were red-orange.

The teeth of Indominus was tyrannosaurid which must have came from its base genome T. rex and were 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. Another trait that came from Tyrannosaurus being in its gene pool was the massively strong bite force it had, which Indominus could use to even crush a bullet-proof Gyrosphere or break the neck of an Ankylosaurus. The Indominus' lower jaw was slightly longer than the upper jaw, which gave it something of an underbite.

Its large size is attributed to Giganotosaurus. Interestingly, I. rex could reach 50 ft as an adult 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. The hybrid could also detect the thermal signatures of others as well due to the pit adder DNA. The snake DNA may also be the reason why it could open its jaws wider than any of InGen's cloned theropods. Finally, the Velociraptor DNA 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.

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, as she killed and ate her own sibling, which was the first thing she did as soon as she hatched. However, since the I. rex who had exhibited these traits had a rough upbringing these behaviors may not be natural. 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.

Isla Nublar Incident (2015)
"We have an asset out of containment!"

- Claire Dearing

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 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 Indominus rex 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 Nick and worker Ellis 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 Ellis 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 Nick, 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.

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.

This Indominus might have been responsible for opening one of the Gyropsphere 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, she agitated one of the Ankylosaurus who proceeded to fight back against her 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. 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 Grady and Claire Dearing 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. As the freed pterosaurs lead 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, she communicated with the raptors and 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, 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. With Owen's attempt to regain Blue's trust by removing her camera only a few minutes before the hybrid's arrival, she then decided to make him the alpha again. Blue screeched at the I. rex, who responded by knocking her into a wall, seemingly killing her. The raptors, now aligned with Owen's group again, proceeded to attack the Indominus while Owen Grady provided suppressive fire with his rifle. But the fight ends fairly quickly as she easily kills Delta by tossing her into a grill that engulfs her in flames and Echo by snatching her into her jaws and throwing her 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 by another dinosaur who challenged her: Rexy, Jurassic World's veteran Tyrannosaurus rex. Rexy carried out a heavy assault on Indominus, and the two dinosaurs engaged in a ferocious battle. Though Rexy 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 Rexy 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 Rexy 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 ready to fight the theropods once more, but 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.

Indominus rex appears in the LEGO Jurassic World video game.

Its role in the game's story mode is near identical to its role in the Jurassic World film, except that only one was created instead of two. She appears in all of the Jurassic World story levels.

The amber that unlocks Indominus is found in the level "Out of Bonds" and the boneboxes of that level can be collected to unlock the skeleton skin for the hybrid as well.

Jurassic World: The Game
see Indominus rex/JW: TG

Indominus rex appears in one of Jurassic World: The Game. It could originally be only unlocked by codes from Brawlasaur toys for use in the Battle Arena, but since June 10, 2015, it can be created for the player's park by fusing a Level 40 Tyrannosaurus rex and a Level 40 Velociraptor. There are two Brawlasaur variants in the game, one that is tan with lime striping and one that is light teal blue with dark blue stripes. Regardless of the color, they share the same stats.

LEGO Dimensions
In the mission "Eggspert Opinion", the player(s) must retrieve 10 Indominus eggs that were taken by female dinosaurs during the incident.

Jurassic World
There are two toys of Indominus that are a part of the Jurassic World toy line. Retailing for $35, the "Chomping Indominus Rex" has the ability to change skin color and can let out a roar upon pressing down on its arms.

Another figure that is packaged with a Gyrosphere with a mounted disk launcher has a piece of skin that can be slid back to reveal battle damage and pulling the tail of the Indominus figure causes it to bite in a downward motion. This battle pack was also packaged with the Ankylosaurus figure from the same line as a exclusive.

A biter Indominus figure was also made that would snap its jaws when its tail was pulled down.

I. rex is also a part of the Hero Mashers assessment where its parts can be used with other toys in the line to make unique creations. It is packaged with a Velociraptor hero masher and several other parts, including a Brachiosaurus neck. The same Hero Masher also had a stand-alone release which included a miniature Gyrosphere.

There was a "Brawlasaur" figure of I. rex that was included with an Ankylosaurus "Brawlasaur". Another brawlasaur figure of I. rex was included in the brawlasaur battle set along with a Tyrannosaurus rex brawlasaur. This means that the Indominus rex is the only hybrid with multiple Brawlasaur figures.

LEGO Jurassic World
A figure of Indominus rex will come in the LEGO Jurassic World set 75919 Indominus rex Breakout. She has poseable legs, jaws, head, arms, hands, and thumbs. Her head is as large as a minifigure and is able to fit one between its jaws.

Zoomer
A robotic Indominus rex was created for the toy line.

Jurassic World: Dino Hybrid
A figure of Indominus similar in appearence to the Level 40 Indominus rex from Jurassic World: The Game will retail for $34.99.

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

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.". The filmakers started with Therizinosaurus because of its large arms and claws when designing the hybrid. One early design by Aaron McBride was similar to the one seen in the film, but had a more triangular like that seen in members of  (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. In the storyboard by David Lowery the Indominus resembles McBride's design with its arms somewhat shorter. 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. Then Glen McIntosh created descriptive illustrations and sketches to emphasize its osteoderms and defined several of its skull fenestrations, particularly the and the.

One early design that displays these traits featured it with a skull that resembled  with osteoderms the size of a large theropod like Tyrannosaurus or Gigantosaurus 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. 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. As the design process continued the Indominus was given exposed teeth like a crocodile to make it more menacing in appearance. One early conceptual design that showcases this trait had a head that was neither tyrannosaurid, carcharodontosaurid, nor abelisaurid in appearance, as well as having shorter hand digits with long therizinosaurid claws unlike the final version and iguana-like spikes running down its back. Colin Trevorrow liked this trait, and thus it was implemented in the final design of the Indominus.

ILM further gave the hybrid its signature underbite to contribute towards giving it a menacing look. There eixts three concept art pieces that showcase its underbite and are close to the hybrid's finalized appearance. The first has a more triangular antorbital fenstra like that seen in carcharodontosaurids with thick quils 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. The second known design depicts it with a wider skull and without quils 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 quils. At some point the design of the eye color and eye shape of the final Indominus was based on a.

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, , and MARI to complete the computer generated model of the Indominus rex. 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". 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 pf "cute".

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 that 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 hybrid also resembles an 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  or the fictional Vastatosaurus rex from. 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". Another working name for Indominus rex was "Diabolus rex" or "D. rex". 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?" But if Axis Boulder is entered it will say it is an unknown command. In David Lowery's storyboards for Jurassic World, the dinosaur hybrid behaves differently. After killing the Ankylosaurus, it is shown to eat the Ankylosaur, 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 chapter "Tyrannosaur" and. The scene where the I. rex bites th 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. 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 through 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.

The roars of Indominus were made from the vocalizations from many different animals. To give the hybrid's vocal mass, vocalizations from es, s, s, s,, es (such as s), s, and es were used. The sound designers for Jurassic World did not use sound effects that were similar to the Tyrannosaurus from the films to differentuate the Indominus from the famous theropod and wanted it to sound irritatble to the viewers to make them dislike the hybrid. 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 wakes into the river nearby where it is then killed by a mosasaur that was present since the second issue.

Its camouflage ability resembles the Carnotaurus from the novel 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.



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

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 upcoming video game  bares a resemblance to the Indominus rex.
