The first kill
Simon Massarani wanted a perfect creature for his park. A theropod that would be bigger than the Tyrannosaurus rex they had. Bigger, louder, faster and more teeth.
The genetics-team of Jurassic World got the job to create their first dinosaur-hybrid. Henry Wu himself led the operation.
The new creature was chosen to have the basic genom of a Tyrannosaurus rex. The creature should have a certain resemblance with the most famous of all dinosaurs. A other genom was from the furious Velociraptors. Through this it would get the speed and agility it needed.
Other dinosaurs that were chosen to create the new attraction was the mighty Giganotosaurus caroliini, Carnotaurus sastrei, Rugops primus and Majungasuarus crenatissimus. These creatures gave details like thicker scales and the crests above the eyes.
In order for the creature to grow faster, cuddle-fish-DNA was added as well as tree-frog for it to adapt the tropical temperature of Isla Nublar.
The new creature was called Indominus rex, the untamable king.
Two creatures were hatched, two female siblings. They looked like pale allosaurs that had long arms and thick skin. The two creatures where out in an enclosure filled with trees and bushes, but that had also high walls.
The creatures got fed with a crane and got plenty. They grew bigger through the cuttle-fish-DNA and when they reached the length of about 30 feet, something happened.
One of the siblings was asleep under a palm tree, when the other one approached.
The one that was awake stared at the sleeping one and had a feeling it never had before. To eat. Not just to eat, but to do something to eat. Hunt. Kill. Rip apart.
The Indominus that was awaked attacked the sleeping one. The powerful jaws came around the neck and broke it. The sleeping one didn't even get the chance to wake up.
The mouth of the living one was filled with blood, which aroused the predator. The first hunt, the first kill.
The living one ate her sibling without any form of moral or ethics getting in it's way.
The humans didn't react to this. They called it a small mistake in the creature, but they didn't know that this was just the start.
Indominus had gotten blood in her mouth and she liked the taste. She loved even more the feeling of ending the life of an other living being. But she needed to get our of this cage that these hairless apes had built for her. She wanted to see the world outside and all the kinds of prey that was out there.
She wanted out, and she would get. She needed to hunt.
