| Okay, I'm not quite sure what you're doing here... other than playing with fire. An Indominus rex? You are creating a hybrid. A dangerous hybrid. You are not only creating life, you're condemning it. Hopefully not your own.|
Indominus rex, or I. rex for short, is a genetically modified species of dinosaur, created by InGen by combining the base genome of a Tyrannosaurus with that of a Velociraptor. The first official hybrid created by InGen, it also contained the genetic material of numerous other species, including dinosaurs such as Carnotaurus, Giganotosaurus, Majungasaurus, as well as an assortment of modern species.
The creation of Indominus requires the complete genome of Tyrannosaurus and Velociraptor, and can subsequently be unlocked on the islands of the Muertes Archipelago via the Research Centre once the player has reached Isla Pena. The Indominus rex exclusive Adaptive Camouflage Gene was added with the Secrets of Dr. Wu DLC.
The brainchild of Dr. Henry Wu, Indominus rex was originally created by InGen to revitalize public interest in Jurassic World on Isla Nublar, which, after operating successfully for over ten years, had begun to experience a decrease in visitor rates. By combining the genome of Carnotaurus, Deinosuchus, Giganotosaurus, Majungasaurus, Rugops, Therizinosaurus, Tyrannosaurus, and Velociraptor, as well as the genome of modern animals such as cuttlefish, tree frogs and pit vipers. Two Indominus were born and as the years past by, one ate the other.
However, with the extreme intelligence of a Velociraptor, Indominus escaped from its exhibit and caused mayhem across Isla Nublar, though was ultimately stopped due to the combined efforts of the park's T. rex, a Velociraptor named Blue, and the park’s resident Mosasaurus.
Dragged beneath the waters to its death, the skeleton of Indominus was later discovered by a team of mercenaries sent to the island, who recovered a piece of a bone from the dead hybrid. Despite sustaining attack by the T. rex combined with casualties by the Mosasaurus, the mercenaries received the material and brought to Dr. Wu, who used it during the creation of Indoraptor, which combined the Indominus genome with that of a Velociraptor. After the death of Indoraptor, the Indominus bone was crushed by the T. rex, preventing its use in the creation of more hybrids.
| The Indominus rex is a magnificent creature. If evolution had the time... well, we've just hurried things along a bit. And the result is nothing short of spectacular. So don't dilute the value of my work. Or you'll be dealing with me. Directly.|
Rows of spines or quills are also present on its neck. The arms are massive and very dexterous, due to the inclusion of Therizinosaurus gene. The base genome of Indominus is ghostly white with deep red eyes.
Indominus rex is an incredibly aggressive and intelligent carnivore, with an extremely high intolerance for deviations from its comfort levels. Even in comparison to other large carnivores such as Tyrannosaurus, Indominus is an asocial animal which doesn't tolerate other members of its species in its enclosure. It is extremely territorial and aggressive, killing virtually anything that enters its enclosure. Given its strength and intelligence, the Indominus is the only dinosaur capable of killing sauropods such as Brachiosaurus and Dreadnoughtus, although it does tolerate smaller carnivores such as Velociraptor.
- The Indominus rex was first officially announced on June 7th, 2018, 5 days before the game's release.
- Indominus rex was the twenty second dinosaur and first hybrid to receive a Species Profile, on June 8th, 2018.
- The base genome of the Indominus rex is based on its appearance in Jurassic World, even to the extent that every Indominus rex in the game sports the scar on the left side of its face inflicted by an ACU member in the film.
- Unlike its film counterpart, the Indominus rex is unable to socialise with Velociraptors.
- Due to the quills, or protofeathers, on its arms and head, Indominus rex is technically one of the few feathered dinosaurs in the game. The other being Indoraptor and Velociraptor with the 2001 male pattern, which also possesses similar quills.
- The Indominus rex’s ability to kill sauropods in the game is a reference to its film counterpart slaughtering many of Jurassic World's Apatosaurus.
- The Indominus rex coastal pattern used to be completely black until the release of Update 1.6.
