The Indoraptor is very similar in appearance to the Indominus rex, but its body length is about half of that of its predecessor and it's more raptor-like. It sports talons that are similar to those of a Velociraptor, and its color is primarily black with a golden-yellow streak running from the base of the neck to his tail, which bears strong resemblance to Blue's metallic blue streak. Like the Indominus rex, the Indoraptor possesses hands with four fingers, an opposable thumb and three main digits. The shape of its head bears a resemblance to that of a Tyrannosaurus rex, and he has a sprinkled red mark around its eye orbit. It also has a small display of quills adorned on the back of its neck, much like the JPIII Velociraptor male variant. The skin around the Indoraptor's mouth is flaky and peeling away in some areas and is also sickly-looking, with ragged teeth similar to those of the Indominus rex. Its head also bears two crests above its eyes, similar to that of an Allosaurus, although a little smaller. It is typically shown walking in a quadrupedal stance, though he can stand, walk, and run bipedally on occasion, which gives him an intimidating look that towers over his prey.

The Indoraptor, like its predecessor, the Indominus rex, exhibited cunning and sadistic behavioral traits. It derived pleasure not only from hunting for sustenance but also from engaging in playful torment of its prey before delivering the final lethal blow. However, a significant distinction can be drawn between the two creatures in terms of their underlying motivations. While the Indominus rex may have acted out of neglected circumstances and formed limited positive relationships, the Indoraptor endured explicit mistreatment throughout its life, aimed at intensifying its predatory instincts. This suggests that the Indoraptor's inclination to kill may have been a result of deliberate conditioning.

However there was one human who the Indoraptor loved and acted like a pet towards and this of course was a young girl named Maisie Lockwood who’d imprinted on him when he was young. Maisie was the only one who didn’t abuse the Indoraptor, Maisie called him Ripper. When Maisie was a little girl she had tea parties with Ripper and dressed him up in cute little costumes, bow ties and top hats and stuff. Maisie spoke in an English accent and Ripper kind of did too, not the traditional way but just in the tone he spoke it sounded more English and eloquent than the other dinosaurs.

One day Maisie came down and decided to release Ripper and they snuck out together during an auction.

Ripper was a curious Dino and he stuck his tongue out for the rain once they were outside and Maisie giggled It’s rain, Ripper!
