Jurassic World Rebirth: What Dinosaurs Make Up the Distortus Rex?
The dinosaurs of the Jurassic Park and Jurassic World franchises are—and always have been—genetic monsters created by arrogant mad science hellbent on tampering with the natural order. No creature represents that better than Jurassic World Rebirth's grotesque mutant abomination known as the D. rex.
A common fan complaint about the Jurassic World franchise often has to do with its growing reliance on mutant hybrid antagonists like the Indominus rex and Indoraptor. Why, they argue, can't the series simply return to the concept of regular dinosaurs?
What viewers seem to forget, however, is that InGen's menagerie of resurrected animals are—and always have been—Frankensteinian abominations cobbled together from incomplete strands of fossilized DNA and amphibian genetic material.
For all its pomp and circumstance, John Hammond's billion-dollar enterprise on Isla Nublar was nothing more than a mission of haphazard arrogance built on an unstable fault line of mad science hellbent on tampering with the natural order, consequences be damned.
Ian Malcolm (Jeff Goldblum) really did put it best when he said: “Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should."
When the Masrani Corporation acquired the bankrupt InGen and opened Jurassic World, it not only failed to heed the mistakes of the past, but took them to another level with bigger, more ferocious, and, as it turns out, wildly unpredictable attractions like the Indominus rex.
No creature represents that grotesque disregard for the ethical implications of genetic engineering better than Jurassic World Rebirth's Distortus Rex, a lumbering, bulbous-headed freak with six appendages and a face only a mother could love.
While the mutant's origin is never explained, Rebirth director Gareth Edwards saw the D. rex as a Tyrannosaurus "cranked up to 15," the filmmaker told Entertainment Weekly in June 2025, "and it had gone wrong because of that."

Also speaking with EW, the film's screenwriter, David Koepp, drew attention to the fact that the creature was the 26th iteration of some twisted experiment to create a star attraction beyond anything park visitors had seen before.
"Clearly they should have stopped about 20 versions ago because it just got worse and worse and worse," said Koepp, who previously wrote the screenplays for Steven Spielberg's Jurassic Park and its 1997 sequel, The Lost World.
"I thought somehow they kind of crossbred a sauropod with a predator, like a T. rex, and the head would be gigantic," he added. "I liked this six-limbs thing. So that was fun. You just got to make up monsters."
