Through the years, the dinosaurs have grown bigger, faster, and more intelligent-terrifying with every installment from The Lost World to Jurassic World: Dominion. But dinosaurs have never been one and all.

Jurassic World Rebirth introduces a new mutant dinosaur that proves to be a far more dangerous threat than even the terrifying and iconic T-Rex.

The Distortus rex is introduced during a flashback sequence at the very start of Jurassic World Rebirth, where there’s a “containment failure” at the InGen research facility on Ile Saint-Hubert, thanks to a rogue candy rapper.
