The Indominus Rex

# Indominus rex

***Indominus rex*** was one of the two main antagonists of the Jurassic World film, and the secondary antagonist of the first season of the Netflix series Jurassic World Camp Cretaceous. She is the latest attraction in Jurassic World The hybrid 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*,[5]*Carnotaurus*, *Giganotosaurus*, *Majungasaurus*, *Rugops*,[1]*Pycnonemosaurus*, *Quilmesaurus*, *Viavenator*,[7]*Deinosuchus*,[6]and *Therizinosaurus*,[2] as well as modern animals such as cuttlefish, tree frogs,[5] and a pit viper snake.[2]

### Creation

#### 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.[8] On May 21, 1997, he created *Karacosis wutansis*, a hybrid plant.[9] On April 5, 2009, another hybrid was created.[10]
Years after opening, Jurassic World's success was lower in 2011 unlike the previous years of its operation.[11]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.[12] The result was a genetically modified hybrid of several dinosaur genera and modern animals. Development of the hybrid began in 2012[13] 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.[14]

#### Characteristics

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. 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.[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 colour.

The teeth of *Indominus* was from *Deinosuchus*DNA,[6] 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.[15] Another trait that came from *Tyrannosaurus* being in its gene pool was the massively strong bite force it had,[2] (though it could also could get some of the bite force from *Deinosuchus* DNA as well) which *Indominus* could use to even crush a bullet-proof Gyrosphere or break the neck of an *Ankylosaurus*.[5] 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*.[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 *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.[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.[16] 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.
