This is Dusty, and she is a very upfront and personal Indominus Rex.

Being born with a group of three other Indominuses, Dusty was always the alpha. She was the biggest of the bunch, and made sure that they knew that she was the one in charge. One of her siblings tried to challenge her for dominance, and she mercilessly ate and digested them. After that, neither of the others even dared to look at her the wrong way.

But one day, the humans holding them forced them to fight to the death. The other two killed themselves as they didn't want to fight Dusty. Her brother killed his weaker sister, but she managed to cut his throat deeply before she died, and he died shortly after her. Dusty was devastated as deep down, she did care for her siblings. From that moment on, she hated humans and wanted to kill any human she saw to avenge her siblings' deaths.

But not long after, she broke out of the facility and escaped into the woods, and managed to disappear even with her desert-like skin colors. They sent many search parties out for her, but they never found her.

She was on her own for two years before she encountered a wandering human boy. While her primal instincts were telling her to eat and kill him, she just couldn't bring herself to hurt a him specifically. She offered to take care of him, and, despite his initial fear, he accepted. She soon learned that the boy's parents died in a car crash and he was dumped in an orphanage by his aunt and uncle, who hated him already.

She comforted him, and the two of them grew closer than magnets and metal. Her love and care towards him eventually led to her new way of keeping him safe and warm in her belly. He was very scared, but they had been together for a few months, so he decided to trust her. She gently swallowed him down, and he quickly started enjoying being safe as well as closer to her than he ever had been before. And this became a normal thing between the two of them, and even developed into a fun game.

Dusty likes only him, and any friends that he has. Any other humans, apart from children, she still hates, but not as much as she did before she met him.

Adopted from  CobaltTheRighteous and the base is also made by them as well.
