Deinosuchus DNA was used to form the crocodilian teeth of the Indominus that were used in grasping the flesh of opponents. Abelisaur genes ( Carnotaurus, Majungasaurus, Rugops, Pycnonemosaurus, Quilmesaurus, and Viavenator) were added to act as a biological form of armor that absorbed most of the incoming attacks. Including the shape of the head in some parts from Giganotosaurus. It was mentioned that the Indominus rex would be larger than the T. Giganotosaurus DNA was added for the large size of the Indominus. Velociraptor DNA was added for high levels of intelligence and the ability to make plans and decisions. It also gave the Indominus rex an incredibly strong bite that could crush bulletproof glass. The genome of Tyrannosaurus rex was used as the base genome for the hybrid. There were also the DNA of modern animals such as cuttlefish, tree frog, and a pit viper snake. Some of the known species that were included were Velociraptor, Carnotaurus, Giganotosaurus, Majungasaurus, Rugops, Pycnonemosaurus, Quilmesaurus, Viavenator, Deinosuchus, and Therizinosaurus. The hybrid was created by modifying the genome of a Tyrannosaurus rex with the DNA of various other theropods.

In the film Jurassic World, she was going to be the latest attraction added to the park for higher profits. She was one of the largest existing theropods in the Jurassic World film, as well as the film's main antagonist, the posthumous overarching antagonist of Jurassic World: Fallen Kingdom, and one of the two overarching antagonists (alongside Henry Wu) of the Netflix series Jurassic World: Camp Cretaceous (specifically the central antagonist of Season 1 and a posthumous antagonist of the subsequent seasons).
