The Indominus rex is a man made, fictional species of Dinosaur created from the DNA of numerous different Dinosaurs mixed into one, ultimate predatory Dinosaur with the intended purpose of replacing the aged, elderly Tyrannosaurus from the first Jurassic Park as the mascot for Jurassic World's successful park. However, despite proper containment for an animal of it's size having been met, the I. rex manages to trick the Jurassic World employees into thinking it had escaped via climbing over it's pen, and thus engineered it's actual escape into the jungles of Isla Nublar, where it goes on a killing spree where, rather than eating victims, simply hunts them for sport according to the second trailer for the upcoming movie.


According to the official website, Indominus rex is has an Aggression Index of Very High, and is solely carnivorous due to the Dinosaurs used in the cloning procedure to create it. It's name means "Fierce or Untamable King", and it's sole habitat is Jurassic World for the obvious reasons of being a man made species. It's capable of reaching running speeds of 30 mph "while confined to it's enclosure", meaning it's possibly even faster than that. It's roar is estimated to reach 140-160dp in loudness, which rivals that of a 747 plane taking off and landing, meaning the creature is extremely loud with it's roar. It's size is (currently) at 40 feet in length, with it's weight having yet to be determined. It is also shown to possess a camouflage ability similar to a Cuttlefish, but it is unknown how effective this is due to the fact this particular method of camouflage requires very minimal movement based on the behavior of an actual Cuttlefish.

It's arm strength, based on the second trailer, is very powerful, and it's four digit hands are capable of grabbing smaller creatures thanks to an opposable thumb, and it's claws are powerful enough to shatter the glass on the spherical touring vehicles used on the ground in Jurassic World, whereas no other Dinosaur on the park posed a threat to these same vehicles. It's intelligence, possibly THE most dangerous thing about the I. rex aside from the camouflage, allows the I. rex to solve problems and plan scenarios just like the Velociraptors the series is best known for doing the same. However, it is much more apparent that the I. rex is doing this on a much more malevolent intent in comparison.

LEGO: Jurassic World

The I. rex is the only Dinosaur whose parts can grant a customized Dinosaur the ability to turn invisible. This is activated, in the 3DS version, by holding down the A Button. While camouflage is activated, actions such as attacking or roaring with the Y Button will be inaccessible.


Not much is currently revealed about the I. rex's behavior, but based on the Superbowl Trailer, almost all of it's own activities outside of hunting for food is continued hunting, but purely for sport. It's interactions with the lone T. rex and the Velociraptors in the island are currently unknown, but it's without a doubt that I. rex and the Velociraptors will confront each other due to how the Velociraptors are used in Jurassic World. Indominus rex, meanwhile, has been shown to be capable of slaughtering at least five Apatosaurus Sauropods, meaning not even Sauropods (Large sized herbivores protected against predators because of their size) will be safe from Indominus rex.

Not much is known to actually terrify Indominus rex, and only two instances have been known to frighten it; an explosion from a helicopter crash, and the inevitable confrontation with a pack of Velociraptors and a T. rex, to the point the latter is what leads Indominus rex to her doom via being pushed far too close to the Mosasaurus enclosure waters, and thus allowed for the much larger Mosasaurus to grab the I. rex in her jaws and carry it back into the pond, thus killing the I. rex as a direct result.
