WARNING: This article contains spoilers for Jurassic World: Fallen Kingdom, in theaters now.
The first Jurassic World film followed through with the idea of man using DNA samples safely preserved in amber to clone all manner of dinosaurs, as they had walked the Earth millions of years ago.
This practice was taken even further in the first film of this new trilogy by having Henry Wu and the InGen scientists play God by not only re-creating the dinosaurs that had existed, but by creating an entirely new species to boost the dwindling sales of the Jurassic World theme park. The result was the Indominus Rex, a monstrous creature who was not bred for entertainment but for destruction. When it used its ability to camouflage itself, the incredibly intelligent creature devised a plan to escape, and once it was free, it wreaked havoc upon the park -- something that, as we all know, led to Jurassic World's ultimate downfall.
As we head into the sequel, we quickly realize Henry Wu didn't learn his lesson at all. Instead, the mad scientist continued his work, using the Indominus Rex as the stepping stone to an even better, even deadlier dinosaur. Fallen Kingdom introduces this new creature as the "villain" of the film, a terrifying dinosaur that is more monster than animal: the Indoraptor.
As its name implies, the Indoraptor is a hybrid of the Indominus Rex and the Velociraptor species. But while the Indominus was a gigantic beast the size of a T-Rex, something that made it relatively easy to see coming, the Indoraptor is significantly smaller, and far more dangerous. While we don't have a detailed breakdown of all the dinosaur DNA the Indominus had in its genome, we do know that there was some Tyrannosaurus Rex in there which gave it its teeth, some Abelisaurs, which gave it its bony horns, as well as features from the Carnotaurus, Majungasaurus, Giganotosauraus, which gave it its massive size, and the Rugops.
On top of that, it had the DNA of various animals like the tree frog, snakes and cuttlefish which gave it special abilities to make it an even fiercer hunter. Finally, it was revealed, late in the game, that there has also part of the Velociraptor in the Indominus Rex, which gave it its heightened intelligence.
