In 2015's Jurassic Park sequel Jurassic World, the theme park was open to a new attraction, the Indominus Rex. The new hybrid creature escaped and was the most dangerous of all the escaped dinosaurs. Concept artist Ian Joyner has shared some early concept art for the Indominus Rex that never ended up being used in Jurassic World.
In Jurassic World, the Indominus Rex was a new dinosaur created by Ingen's Dr. Henry Wu by combining different dinosaur DNA, most notably the T-Rex and the velociraptor. On his page, Joyner -- a freelance concept artist who has worked on movies and video games -- describes the artwork as "an early exploration for the Indominus Rex in Jurassic World. No one particular dinosaur was referenced, as it was a hybrid creation."
Joyner's Indominus Rex has the familiar outline of a Tyrannosaurus Rex, but with some big differences. The Indominus Rex envisioned here has sort of a green and black striped look, which kind of resembles jungle camouflage instead of the white default color of the final design. The teeth are also completely black and a series of spikes run along the tail, spine, the back of the neck and the head. The hands are also larger than a T-Rex, with what looks like four fingers.
Ultimately, Jurassic World went with a different concept of Indominus Rex, but this is an amazing look at a dangerous new creature.
