<Li> Jump up ^ An infographic released by Universal Pictures revealed that its long grasping arms were the result of Therizinosaurus DNA . The infographic also mentioned its opposable thumbs but did not reveal their source . </Li> <Li> Jump up ^ The name Indominus rex is derived from the Latin words indomitus meaning "fierce" or "untameable" and rex meaning "king". Paleontologist Jack Horner, the scientific advisor of the films, said that the long grasping forelimbs of the Indominus rex were inspired by Therizinosaurus . "I started the process with a dinosaur called Therizinosaurus that has big grasping arms . That was the most important thing--the grasping arms and its color . It's white," said Horner . He went on to say "Indominus rex is made as a transgenic animal, meaning we've taken genes out of one animal and put it in this one ." </Li> <Li> Jump up ^ The Indominus rex cannibalized its younger sibling as her isolated upbringing and lack of socialization with other dinosaurs caused her to develop psychotic tendencies . In Jurassic World, Simon Masrani tasked Owen with inspecting its paddock for vulnerabilities . It later fooled Claire and Owen into thinking it had escaped by cloaking its thermal signature and leaving claw marks on the walls of the paddock, prompting Owen and two others to enter the paddock . The Indominus rex ambushed them while they inspected the paddock . In the subsequent confusion, it killed the other two men and escaped by breaking the closing paddock gate . It then began heading south towards the visitor area . Masrani sent a containment unit to subdue it with non-lethal weapons but it killed most of the unit . It began hunting and killing other dinosaurs for sport after the encounter, wreaking havoc along the way . Shortly after, Masrani and two troopers outfitted a helicopter with a heavy machine gun to kill the Indominus . It escaped the gunfire by breaking into the park's aviary, releasing a flock of Pteranodon and Dimorphodon, some of which collided with the helicopter, causing it to crash . Later that night, Vic Hoskins dispatched the four Velociraptors under Owen's training, to track and kill it . Once they located it, it began to communicate with them and made them attack the accompanying military unit . One of the raptors got killed in the process but the survivors eventually rekindled their bond with Owen and attacked the Indominus . It killed two of the raptors and attacked Owen, Zach and Gray . They were saved when Claire released and lured the park's Tyrannosaurus rex into a battle with it . The Indominus rex gained the upper hand until the surviving raptor, Blue, joined the battle . It was quickly overpowered and cornered at the edge of the park's lagoon, where the Mosasaurus dragged it underwater . </Li> <Li> Jump up ^ In Jurassic World: Fallen Kingdom, a team of mercenaries collected a fragment of bone from the remains of the Indominus rex to retrieve its DNA . Henry Wu eventually combined its DNA with Velociraptor DNA, among others, to create the Indoraptor . </Li>
