In Jurassic World, the park’s genetically engineered hybrid dinosaur is the Indominus rex.
The Indominus rex is created by combining genetic material from several animals and dinosaurs. In the film, its engineered traits include camouflage, intelligence, and the ability to conceal its body heat, making it unusually difficult for the park’s staff to track.
The hybrid is introduced as a new attraction intended to increase visitor interest. Its escape exposes the danger of designing animals primarily as commercial spectacles, and it becomes the central threat faced by Owen Grady, Claire Dearing, and the park’s visitors.
Indominus rex is different from the Indoraptor, which appears in Jurassic World: Fallen Kingdom. It is also not a naturally recognized dinosaur species; the name belongs to the fictional hybrid created for Jurassic World.
