Indominus Rex

Warning: Spoilers may follow.

"You made a genetic hybrid. Raised it in captivity. She is seeing all of this for the first time. She does not even know what she is. She will kill anything that moves."

"You think the animal is contemplating its own existence?"

"She is learning where she fits on the food chain, and I'm not sure you want her to figure that out."

~Owen Grady and Simon Masrani discussing the Indominus rex.

The Indominus rex is the main antagonist of the 2015 summer blockbuster film, Jurassic World. She is a new attraction in the park Jurassic World who was created by Commander Vic Hoskins and Dr. Henry Wu.

Appearance
"It can camouflage!"

~Katashi Hamada discovering the Indominus 's abilities.

The Indominus rex is a tall, slender hybrid dinosaur with red eyes, quills, knife-like claws, saw-like teeth, and large feet. She is sometimes compared to Rudy due to her white scales, and the Vastatosaurus rexes due to her aggressive behavior.

Origin
"They just went and made a new dinosaur? Probably not a good idea."

~Owen Grady about the Indominus rex.

The Indominus rex was made of a deadly combination: Tyrannosaurus rex, Allosaurus, tree frog, cuttlefish, Velociraptor, and many other creatures. She was also speculated to be part human; however, that isn't true, as she would have talked. With these traits, she could destroy a gyrosphere, turn off body heat, camoflauge, and communicate with Velociraptors. The I. rex was also made up of many more dinosaurs and modern animals, such as Giganotosaurus and snakes.

Personality
"She's killing for sport."

~Owen Grady after seeing several Apatosauruses slaughtered by the Indominus rex.

The Indominus rex was an evil hybrid dinosaur ever since her creators, Hoskins and Wu, unintentionally put her in a cage too small for her species. This caused her to go out of control, and eventually, she became a power-hungry, blood-thirsty monster. Like the villain from the first film, the Big One, she was a deadly killing machine, but she was more dangerous, evil, and violent, and unlike the rest of the carnivorous dinosaurs who were driven by natural instinct, the Indominus was driven by pure sadistic pleasure, which led to her killing for sport, which she will not stop. At the end of the film, the Indominus rex was eaten alive or possibly drowned by Mosy for her evil character.

New Creation
In the beginning of the film, we see an egg hatching, and the Indominus rex was born. Twenty years after the events of the original film, Dr. Henry Wu, Commander Vic Hoskins, and their research team, InGen, formed a new species by using the genes from other dinosaurs to spark more attention of their successful park, Jurassic World in Isla Nublar, which resulted in the hatching of the Indominus rex.

Inspecting the Safety
Of course, they originally wanted to have two Indominus rexes, 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 main protagonist of the film) to inspect the Indominus rex to ensure the park's safety.

Tricking Owen
Unfortunately, the Indominus rex fakes her escape by scarring the wall, turning off body heat, and camouflaging herself. Owen and two construction workers, Ellis and Nick, come in and think she escaped, but the I. rex reveals herself, and she chases them. She snaps Ellis with her claws and kills him, but the other two escape. The other construction worker, Nick, tries to shut the gate to get Owen out of her enclosure, but the Indominus rex manages to destroy the gate by using her head, free at last. Owen hides under a car, while Nick hides in front of a truck. The Indominus rex decides to kill Nick first, so she throws the truck to the right. Finally, she snaps him with her jaws, killing and eating him, so Owen cuts a gasoline wire under the car. When the I. rex puts her snout next to the car, all she could smell is gasoline, so she leaves to kill more prey and kill Owen later.

Ambushing the Soldiers
Eventually, Katashi Hamada and his crew decide to hunt down and kill the Indominus rex, but the I. rex camouflages herself again, and Katashi realizes it. She grabs him and throws him into a nearby pool of water. Then, the Indominus rex stomps him with her right foot, killing him. As she walks in the pool, she kills more of his soldiers. She then walks out of the pool, and she kills a man shooting her.

Attacking Zach and Gray Mitchell
After that, Zach and Gray are in the gyrosphere inspecting four Ankylosauruses in a restricted area, with the I. rex just behind them. She kicks it to the Ankylosauruses, making them panic and damaging the gryosphere. However, one of the Ankylosauruses defends Zach and Gray from the I. rex, but she kills him. She then bashes the gryosphere, trying to kill them. Fortunately, they escape, and the I. rex puts it down, realizing they did so. She then chases them to the edge of a waterfall. While they jump in, the Indominus Rex tries to snap them, but misses. They jump in the waterfall, and the I. rex, thinking that they drowned, roars in victory, and leaves. She then enters the Gryosphere Valley and kills an entire herd of Apatosauruses for sport, with no survivors.

Murdering Masrani
Masrani decides it is too dangerous to leave the I. rex alive, so he takes matters into his own hands. He and two military soldiers shoot her from a helicopter, but she reaches the Aviary and shatters the glass. She then roars at the pterosaurs there, commanding them to attack the helicopter. They do so, and the results are Masrani's death, the two soldiers' deaths, and the helicopter crashing into the Aviary, exploding it. The Indominus rex and the pterosaurs escape the explosion safely, and the I. rex roars at them again, commanding them to attack the park Jurassic World, and they do so.

Manipulating the Velociraptors
At night, Owen Grady, Hoskins, the Velociraptors, and the military soldiers decide to hunt down the Indominus rex once and for all, but the I. rex is able to communicate with the Velociraptors and command them to attack the good guys, and they do so. Owen realizes that she's part raptor, and the raptors attack, killing several people. Commander Vic Hoskins is able to shoot the I. rex with a missile, but the Indominus rex survives, roars in anger, and leaves. Charlie is shot and killed by a military soldier.

Final Battle and Death
The Indominus rex finally makes it all the way to Main Street, and she, along with the raptors, confronts the main characters, but Owen is able to recreate his bond with the raptors. Blue screeches at the I. rex, but she responds by throwing Blue against a wall, knocking her unconscious. Then, the I. rex throws Echo into a grill with her jaws, exploding her to death. Delta is snapped by the I. rex 's jaws, killing her. After that, the Indominus chases the main characters, but Claire escapes. She commands Larry to release Rexy from T. rex Kingdom, and he does so. Claire leads Rexy to the Indominus rex by throwing a flare at her. Rexy then battles the I. rex, but is overpowered. When the I. rex is ready to rip her neck open, Blue regains her consciousness, and jumps on the I. rex, scratching and biting her back. Rexy is able to fight again, and bites the I. rex 's neck. She smashes her into several museums and shops, with Blue biting and scratching her back. Rexy then shoves her near Jurassic World Lagoon, where an overgrown Mosasaurus like Mosy can spot her. The Indominus then gets back up, not noticing Mosy. Knowing that she was defeated, she roars in anger, but Mosy beaches herself to bite the Indominus rex 's neck. The I. rex is then being dragged by Mosy into the lagoon where she gets her neck broken, and then eaten in an off-screen scene.

Future
Although the Indominus rex is gone forever, the park Jurassic World will probably not continue because of the mass destruction that she caused in the park. But because of many embryos and cans filled with D.N.A. in a helicopter that escaped the park, there is a possibility that another Indominus rex just like her will appear in Jurassic World II and cause more destruction.

Trivia

 * The word Indominus rex means "fierce and untamable king".
 * Her species is the most powerful species of dinosaur in LEGO Jurassic World.
 * Hoskins intended for her to be in the military, but the Indominus rex never was.
 * The Indominus rex 's teeth are constantly being replaced. This is the same trait that some theropods, sharks, and even snakes have.
 * If it wasn't for Blue, the Indominus rex would have killed Rexy.
 * The way the Indominus rex was able to control the raptors was very similar to the way the Muddy Bewilderbeast was able to control all the other dragons.
 * In a way, she is also similar to Sharptooth: both kill for sport, both tried to kill kids in their films (Littlefoot and company for Sharptooth), (Zach and Gray for the Indominus rex), and they both met a watery fate (Sharptooth got knocked unconcious by the boulder), (the Indominus rex was dragged down into the bottom of Jurassic World Lagoon by Mosy and eaten alive). However, unlike Sharptooth, the I. rex did not drown at the bottom of the lagoon because she had gills and only killed by Mosy's bite-force.
 * If you look closely, you can see that the Indominus rex has gills on her neck, making her impossible to drown and also making her part shark. Unfortunately, it's unlikely that she had a chance to use those gills because Mosy killed her underwater before she could try them.
