D- Rex Analysis by Sagui
Introduction:
“Jurassic World: Rebirth”, a movie releasing on 2nd July 2025, has been met with contempt by some fans. They’re dissatisfied with many things, one of which is the absence of Owen Grady, Claire Dearing, and our all-time favourite velociraptor- Blue. However, fans find the new ‘dinosaur antagonist’, as one may call it, the most concerning matter.
The Diabolus Rex, or the D-Rex, got its name from the Latin word ‘diabolus’, meaning ‘devil’ or ‘slanderer’. The D-Rex’s design was leaked on Reddit by a user, accompanying major plot points and designs of other dinosaurs. The leak, which is now deleted, described D-Rex as a failed clone, a result of the scientists’ failure in creating a Tyrannosaurus Rex in the initial stages of their experiments. They then deposited this creature, along with a few other failed experiments, on an island, the name of which is yet to be revealed. This island will now be explored by a group of people who aim to retrieve the DNA of three dinosaurs for a medical breakthrough.
The D-Rex’s design was inspired by the T-Rex, Star Wars’ Rancor, and Alien’s Xenomorph. It has six limbs in total- two in front like the Rancor, the pair in the middle like that of T-Rex’s, and the two for walking, like that of the Xenomorph. It has a head that looks like that of the Xenomorph, minus the shiny skin on top. For a failed experiment, I think that the D-Rex was well designed- it can haunt the early teens’ nightmares like the Indominus Rex would do mine.
Now, let us see how these mutations could help our new failure friend.
THE RANCOR:
The Rancor in Star Wars was a creature who could be trained to follow orders and even develop strong bonds, both physically with its arms and emotionally with its heart. While the D-Rex has not inherited the Rancor’s emotional availability, it sure has its massive arms. These long limbs could help the D-Rex hunt and catch its prey, wound its enemies, and play ‘kill’ for fun. These attacks, due to their massive size, are unblockable and will be accompanied by deadly bites and powerful claw attacks. Moreover, the D-Rex can hold its prey down while feasting on it- not that it is required if it's a human.
THE XENOMORPH:
Now we come to the Xenomorph. The D-Rex’s head and back limbs were inspired by the Xenomorph. D-Rex might have a second set of jaws, or inner jaws, and a phallic-shaped tongue, which can spear through almost anything. The hard exterior in the D-Rex’s head protects small spaces to not damage its brain (your tall friend, that way, could also be called a knockoff D-Rex minus the brain). Also, any attempts at hitting it in the head to kill it will be futile.
THE T-REX:
When I think of the T-Rex, the first thing that comes to my mind is ‘RUN’. The second is its cute little front limbs, which one would think are useless. Wrong– while there is no proof of what purpose these limbs served, many scientists speculate that they were used during mating for display, to hold down prey while feasting, or to dig nests.
With D-Rex already having the Rancor’s arms, these limbs might be vestigial for the D-Rex, or they could be used for mating- either way, the eggs would need a warm place to be in, and the long front limbs … don’t quite do the job.
The tail is one of the things the D-Rex inherited from the T Rex. The tail of the T-Rex helps it to not topple over, maintaining its balance; it would serve the same purpose for the D Rex. Taking into account its huge size, it will be even bigger and stronger for it.
What could be the genetic composition of the D-Rex?
In Jurassic World, we do not have the Rancor and the Xenomorph (thank god), so the possible parents of the D-Rex could be the DNA of other dinosaurs, frogs, chameleons, and maybe a potato (I’m being completely serious. It inspired the Rancor.).
Dinosaurs like the Therizinosaurus and many other theropod dinosaurs, like the velociraptor, exhibit skills similar to that of the Xenomorph and the Rancor. Xenomorphs can camouflage like the velociraptors- they share similar survival instincts and analyze their surroundings before attacking. Moreover, the Xenomorphs and Velociraptors both have a Queen or an Alpha.
In the “Jurassic Park” movie, it was mentioned that the gaps in the DNA of the dinosaurs were filled using that of the frog’s, and so, the D-Rex might have frog DNA as well (which frog?).
Overall, I think we should sit back and relax and let Gareth Edwards, the Director of Jurassic World: Rebirth, perform his magic.
This analysis was written in March of this year. Now that the movie is out, my thoughts after watching it are: The D-Rex is a lallu chapati. (Translation: It deserved more screen time.) also, it's called the "Distortus Rex"? i'm a bit lost yeah
