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 a new 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, 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 and a giant sickle claw on each middle finger that I. rex used to grab prey. 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. The Indominus' lower jaw was slightly longer than the upper jaw, which gave it something of an underbite. Another trait that came from Tyrannosaurus being in its gene pool, the hybrid inherited 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. 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 everyone think she escaped and her ability to remember when and where they inserted her tracking implant.

Though they do hunt for food, the first I. rex created 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. 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 before it even hatched, 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.

She then found brothers Zach and Gray Mitchell who were observing 4 Ankylosaurus in the island's Restricted Area 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 the 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, but 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 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 in a jumpscare-like fasion. 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 scarred 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 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 decided to make him the alpha again. Blue then 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 challenges 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 is eventually brought to the ground by the hybrid's strength, destroying the Jurassic Traders Outpost and almost killing Owen Grady and Gray and Zach Mitchell. 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 continued biting and scratching her. Finally, she is flung to the edge of the Jurassic World Lagoon where the Mosasaurus there detected the hybrid and proceeded to pull her under the water to the hybrid's 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 upcoming 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.

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.

Indominus is very similar to the Ultimasaurus, a toy from the toy line Jurassic Park: Chaos Effect 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. In the Jurassic World storyboard, the Indominus is referred to as "Malasaurus" and "Malusaurus". It is also shown to eat the dinosaurs it kills unlike in the final film. Another divergence from the film was that it joined the raptor pack it had recently taken control of in the pursuit of Claire and the Mitchells. 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. 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.

The eye color of Indominus was based on a.

The roars of Indominus were made from the vocalizations from many different animals. To give the hybrid's vocal mass, the sound designers used vocalizations from, , , and. (such as ),, and were used as well. The sound designers for Jurassic World did not use sound effects similar to the Tyrannosaurus to differentuate the Indominus from the famous theropod and wanted it to sound irrtable 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.

Many fans have noted that the Indominus rex is similar to the Baryonyx Rudy from the film  or the fictional Vastatosaurus rex from. The hybrid also resembles an that appeared in the first issue of the IDW comic series Jurassic Park: Dangerous Games. Furthermore, some have noted that Indominus is very in appearance.

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 an animatronic Tyrannosaurus coming out of a waterfall, which the hybrids bites, a reference to the scene in the chapter "Tyrannosaur" and. This scene was later changed to take place in Main Street and for the Indominus to bite the animatronics head off, but that was but it was cut when the script was being written, due to Steven Spielberg pointing out that people might interpret the scene as saying CGI is much better than animatronics. 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.". From the concept art for the film (see below) it resembles an  the size of a large theropod like Tyrannosaurus or Gigantosaurus with arms that were more therizinosaur than the final version. The toy prototype resembles Abelisaurus like the concept art, but is more slender with arms like a Velociraptor and a set of fangs on the front of each of its jaws. In the storyboard by Dave Lowery the Indominus closely resembles Gigantosaurus and its arms are somewhat shorter. Finally, there is a design that is the closest to the one seen in the final film, but lacks horns and quills.

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.

Because many people were disappointed with the design of I. rex, they created the #buildabetterfaketheropod project to make their own hybrid theropods.

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