The Distortus rex is very large, about double the size of a regular Tyrannosaurus, a Spinosaurus, or even a Giganotosaurus. It appears to have the conditions brachycephaly and polymelia, in which the specimen possess a shorter skull and more limbs. It has 6 limbs consisting of a pair of hind legs and 4 arms: a pair of large pillar-like ones that work similarly to apes like gorillas with clawed hands capable of grabbing prey at the front, and a pair of small ones resembling an elongated version of the arms that regular Tyrannosauruses have located closer to the body between the other limb pairs. It moves on its larger arms and hind legs, giving it a great ape-like build as well as a quadrupedal gait similar to dinocephalians like Moschops and pareiasaurs like Scutosaurus. Its head is also large for its size, having an enlarged forehead similar to a beluga whale, as well as a mouth of short but sharp teeth and very small eyes. Its tail is also decently long and its body seems to be hunched at the back. The color scheme of the D. rex consists of yellow with dark-brownish splotches and markings in the back, arm, legs, and tail, including a white underbelly.

The D. rex is extremely aggressive, and appears to attack humans on-sight, though it interacts through feeling and touch before it eats its prey. It is also said in the movie that it is attracted to light (like an insect). It’s clearly carnivorous as well.

You just so happen to see it staring right at you and approaching very slowly.
