Indominus rex

"So you just went and made a new dinosaur? Probably not a good idea."

- Owen Grady to Claire Dearing about the Indominus Rex

The Indominus Rex (I-Rex for short) is the main antagonist of the 2015 summer blockbuster film, Jurassic World.

Description
"She was designed to be bigger than the t-rex."

- Dr. Henry Wu about the Indominus Rex

The Indominous Rex is a man-made hybrid dinosaur created with the genes of other species of theropod dinosaurs (including Carnotaurus, Giganotosaurus, Majungasaurus, Rugops, Velociraptor, Tyrannosaurus Rex), as well as modern animals such as the Cuttlefish and Tree Dart Frog. It is known that the Indominus Rex was designed to be the most dominant of the dinosaurs in size and intelligence, and to be the most menacing of them all.

Isla Nublar Incident (2015)
Twenty years after the events of the original film, Dr. Henry Wu, Vic Hoskins, and their research team in InGen forming a new species by using the genes from other dinosaurs spark more attention of their successful park Jurassic World in Isla Nublar, which resulted in the hatching of Indominus Rex. Of course, they originally wanted to have two Indominuses, but after they hatched, the older one cannibalized her sibling before being placed in her enclosure. After being displayed to Claire Dearing (the park's operation manager) by Simon Masrani (CEO of Masrani Global Corporation and owner of Jurassic World), Masrani requests that he would like Owen Grady (a velociraptor trainer and the protagonist of the film) to inspect the Indominus to ensure the park's safety.

Owen and two of the staff arrive at the Indominus enclosure, only to find out that she has escaped by scaling the wall. However, it turns out that the Indominus has actually faked her escape and ambushed the three, with Owen barely escaping. The two staff, however, were grabbed and eaten by the Indominus, who is now loose on the park. Going against Owen's advice to take down the Indominus, Masrani sends in an ACU unit to stop the Indominus' rampage, but the hybrid used its camouflage ability to ambush the team, resulting the deaths of many of the men while the remaining ones flee away.

Realizing that this has gone out of hand, Claire shuts down the northern area of the park. Zach and Gray Mitchell, Claire's nephews were in a gyrosphere checking out a small herd of Ankylosaurus on the restricted area, but encountered the Indominus, who then kicks the gyrosphere right to the ankylosaurs, causing them to panic and damaging the gyrosphere in the process. During the time, the Indominus manages to fight one anklyosaur before turning it over on its armor and decapitating it. Afterwards, she proceeded to attack the gyrosphere by breaking it, nearly killing Zach and Gray. However, the two escaped by running away from her & jumping off a waterfall to safety, leaving the Indominus to find new prey. As they search for the boys, Owen and Claire soon learn that the Indominus has killed several Apatosaurus without devouring them, realizing that she is killing for sport rather than for food. They enter the old visitors' center, only to be brought a fierce welcome arranged by the Indominus. Fortunately, the two manage to escape alive.

Deciding now that the Indominus is too dangerous to be left alive, Masrani decides to take matters into his hands. He and a couple of InGen personnel pursue the Indominus in a helicopter, but the hybrid ruptured into the Jurassic World Aviary, releasing all the Dimophordons and Pteranodons in the enclosure and causing them to attack Masrani's helicopter and let it fall into the aviary, killing Masrani and the personnel in a brutal explosion. This action caused the visitors to be attacked by them on Main Street, as well as a few infantile dinosaurs to be taken as prey. This also resulted the death of Claire's personal assistant Zaralinda "Zara" Young, who was attacked by a Pteranodon on the Jurassic World Lagoon before the two are devoured by the Mosasaurus.

Following Masrani's death, Hoskins takes over Jurassic World and plans to use Owen's velociraptors (Blue, Echo, Delta, Charlie) to fight back against the Indominus, which Owen reluctantly tags along. However, Owen soon learns that the Indominus had a little of raptor DNA, which allowed the hybrid to communicate with his velociraptors and make them turn against the InGen team. This resulted the deaths of Hoskins, the InGen team, and one raptor (Charlie) while the Indominus fled.

Following the deaths of Hoskins, Charlie, and the InGen team, the three velociraptors rekindle the relationship between themselves and Owen and help him fight the Indominus, realizing now that the hybrid was only using them for her own purposes. Unfortunately, the Indominus was too strong and managed to kill the raptor Echo by throwing her into a nearby restaurant's grill, causing it to explode. The Indominus then kills the raptor Delta by snatching her and throwing her aside. Knowing that Owen and the raptors don't have the strength and power to overtake the Indominus, Claire releases a Tyrannosaurus Rex (the same one from the original film named "Rexy") from her enclosure to even the odds against the Indominus. At first, the Indominus has the upper hand against Rexy, but before she could kill her, the surviving raptor (Blue) arrives to aid Rexy, who then fights back against the Indominus, shoving her near the Jurassic World Lagoon. There, the Mosasaurus rises from the water and grabs the Indominus by the neck, and Rexy, Blue, and the humans watch as the mosasaur drags the screeching Indominus down to the depths of the lagoon, where the hybrid is devoured and drowned to her death.

Despite the fact the Indominus is finally gone for good, her actions are what caused Jurassic World to be permanently shut down as all of the surviving humans head onward to the mainland while the surviving dinosaurs are set free in the wild again following the Indominus' demise.

Personality
"She's killing for sport."

- Owen Grady after seeing dead apatosaurs slaughtered by Indominus Rex

Though it was initially believed to be only driven by instinct, the Indominus Rex's actions imply that unlike regular carnivorous dinosaurs, she is driven by vindictive rage and pure sadistic pleasure, giving the fact that she went too far by laying waste to the cage that confined the pterosaurs, killing or severely maiming several Apatosauruses, using the Ankylosaurs to damage the gyrosphere to make it easy for her to destroy it and relentlessly pursued the human protagonists.

Her sinister nature was the result of both her unstable genetic make-up and unintentional psychological torture that was done by her creators, Hoskins and Dr. Wu, that placed her in an enclosure that turned out too small and also left her isolated from the rest of the dinosaurs. This, in turn, left her in a more ruthless and murderous state. Even compared with other carnivores (like The Big One), I-Rex was more mentally unstable and deadlier. In spite of this, she was still intelligent enough for convincing Owen's raptors to turn against him temporarily.

According to the film director, Colin Trevorrow, the Indominus was designed to serve as an embodiment for 'humanity's worst tendencies' through corporate and consumer excess, created to meet the corporate world's demand for new and unique products in order to provide more entertainment to the park's audiences.

Powers
"It can camouflage!!!"

- Katashi Hamada about its camouflage ability, before being trampled

She was given the powers from each of genetic choices such as her high intellect from the velociraptor but much smarter, her size and incredible strength from Tyrannosaurus Rex DNA with powerful jaw strength as well, cuttlefish DNA to be given the ability to camouflage herself, and powerful scenes.

She had shown her strength in the film, being able to break down the large glass cage for the flying reptiles and able to crush the gyrospheres with her powerful jaw strength, though she did this by using the A nklyosaur. She was even shown to be able take on Rexy, overpowering the T. rex and probably would have killed her if Blue had not intervened.

She was said to be able to run 30 mph in her enclosure, but she can run much faster outside of her cage. Not only did she possessed great speed, she also had amazing acrobatic as she had great gripping clawed hands, able to use her tail whip, and great counter balance to make quick turns.

Her intelligence was super high as she made claw marks on the wall to make Owen and the others think she had escaped, but it was all a trap for the humans to get in the cage, knowing they will come to inspect it. She was shown to be able to remember the tracker that was used on her, so she made her own plan to use it against the humans. As she knew exactly where they were when they created her in her skin and the I. Rex use the pterosaurs to attack the helicopter. She was even able to command the trained velociraptors to make them on her side to attack the humans as she was the alpha for having the velociraptor DNA.

She has a great durable body to take many attacks from her enemies such as guns, the velociraptors' attacks, and Rexy's strength. She took an attack from A nklyosaur. She did not show too much pain as she shows off her high stamina, being able to fight for long periods of time or long distances to chase her prey. However, when the Mosasaurus attacked on her neck, the Indominus screeches in pain as she gets dragged to her watery death.

Having the special power of camouflage to be able to blend in her surroundings that was very powerful to hide from trackers as even shown to turn colors from the DNA of cuttlefish. She was also given the DNA tree dart frog, which allowed her to suppress her heat signature enough to hide from heat-sensitive cameras.

Trivia

 * Although she was created by Hoskins and Wu, the Indominus Rex serves as the main antagonist because she was far more dangerous than anyone else.
 * Indominus Rex is heavily inspired by Lost World: Jurassic Park's portrayal of Carnotaurus in the novel, which has the ability to turn invisible & the unreleased Chaos Effect hybrid dinosaur toy Ultimasaurus.
 * An early working name for Indominus Rex is Diabolus Rex.
 * Indominus Rex is very similar to the Big One from the first movie; they both display a high level of intelligence, they both kill mainly for sport, and they both go so far as to kill their own kind (the Big One killed five members of her own pack, and the I. rex cannibalized her own sibling).
 * It has been speculated by the fanbase that the I.rex may have human DNA inscribed within its genetic code. When Colin Trevorrow was questioned about this possibility in an interview, he made an ambiguous remark about that being revealed in the upcoming future. It is also believed she had snake DNA as well, particularly how she is able to "see" people's body heat.
 * In Jurassic World LEGO Game, I-Rex's camouflage powers were somewhat more advanced where she can nearly become invisible, comparable to villains that can turn invisible like Predators. This however, is simply a gameplay mechanic.
 * Also, in the same adaptation, she has some sort of geokinesis attack where she can summon a straight line of heavy damaging earthwave as long-range attack. Again, this is simply a gameplay mechanic and game-exclusive powers.
 * Her lethality in Jurassic World LEGO Game somewhat lessened, shown where instead killing them, she only K.O.s Echo and Delta during her final battle (both raptors are recoverd not long after she was devoured by the Mosasaurus).
 * Her final fate in the said game is somewhat comical twist, as she was shown playing cards with humans (including Zara Young) within Mosasaurus' stomach, with one of her hand holding a deck of cards and other holding a flare to illuminate the area.
 * Many fans have compared I-rex to Rudy (due to her freakishly white skin), Vastatosaurus Rex (due to her brute strength) or the Muddy Bewilderbeast (due to how she made the protagonists' animal companions turn against them).
 * Despite her name (Indominus Rex) she is actually part Velociraptor.
