Terroraptor

Description
Terroraptors are husks of flesh infused with humans and demons. They resemble raptors but its appearance is a mere manifestation: not connected with the dinosaur species at all. It has an exposed skull while its skin is a composite of rotting flesh. Its teeth are coated with an unknown toxin that decomposes organic material it comes in contact with, making its attacks almost always fatal. Because of it has an unnatural demonic state of being, it can withstand massive amounts of stopping power, however, that does not mean it is invincible. Sustained amounts of heavy damage can inevitably kill it.

History
Little is known of this species. It is believed to be a mutant animal created with the intent to sell as a bio weapon to warring states, mercenaries, and warlords. Although it is not known to venture far from the now defunct Happy Rock Testing Facility, supervision is required, and a platoon of soldiers monitors from the opposing cliffside.

Behavior
A Terroraptor is hostile towards every other species of fauna, attacking unrelentingly on sight. It does not follow normal patterns of survival, it is on a constant hunt barring sleep. It does not display a need for food or other sustenance, meaning it attacks purely to kill. When having not encountered targets for an extended period of time, it will start hiding in wait, hoping it can ambush the unsuspecting.

Battle Stratagem and Threat Level
There is only one logical course of action for those encountering a Terroraptor alone without reliable firepower: run!

Terroraptors can catch up to their prey pretty quickly, so hiding behind things or creating obstructions are your best bet.
