The Tyrannopus is an imposing creature. It possesses a thick black hide, which protects it from injury and helps with thermoregulation. The hide can also change colour and opacity slightly, allowing the animal to better camouflage. It is a fast runner, capable of reaching speeds of around 50 mph in short bursts. Every creature which gets caught with its grasp will be put out of existence by its powerful claws, 12 inches long, and crushing bite of 13,000 psi. The head makes up around 7.5 percent of its body mass, containing two pairs of eyes, a trait common to all Kerbinian Hexapods. The main pair of eyes are able to detect objects from around a kilometre away, and the eyes' focusing ability gives the creature extreme depth perception. The second pair of eyes see more towards the side, but can aid the main eyes. These two secondary eyes are designed to detect infrared and ultraviolet light, allowing the animal to detect heat signatures of prey from very far. The mouth is lined with dozens of sharp teeth, with knife shaped teeth towards the front, for tearing into flesh, and more conical teeth to hold onto the unlucky victim. Once flesh is torn off, the might predator briefly chews on the slab of meat it ripped from its kill's body, before swallowing it in big chunks. The Tyrannopus can swallow around 35 kilograms of meat in a single bite.

The Tyrannopus has 3 pairs of limbs, a trait which defines the Hexapods, and in the Tyrannopus, each pair is somewhat different, though all serve as walking limbs. The first pair of limbs is the creature's main manipulation arms, and 3 of the 4 digits on each hand are long and articulated, tipped with the aforementioned 12 inch claws. They can kill a small creature in one strike, but are usually used to restrain mostly larger prey, whilst the mouth does the killing by biting into the victims throat, cutting off airflow and suffocating it, whilst bleeding it out, and severing its spinal chord. These first two limbs are used least for locomotion, and are even held up when the animal is jogging, or moving in for a kill, although they are used to help change direction when the animal is running. The second pair of limbs serves as the first of the locomotive limbs. Bizarrely, it's claws have shrinked, and split apart the feet.  They also serve a range of uses, such as digging for snacks underground, intermediate distance communication by striking the ground in patterns, helping out the first pair with restraining prey and other unique uses, such as directly battling more powerful prey. The final pair of limbs is packed with muscles to give the animal immense bursts of speed. 

The Tyrannopus has a wide, almost cosmopolitan range, as Tyrannopods have historically been patrolling large swathes of land. A significant portion of them is native to the Iron Mega-Island, a large island located to the south of the large continent on Kerbin's Oriental side. The Island has hosted a large menagerie of Hexapods for a long time, with a few small species even existing nowhere else. Across the Supercontinent, the Tyrannopus has hunted a vast array of Megafauna, competing for macropredatory niches with animals like the Megalopterids, Kerbinian Mammal predators, Asterosuchids, and even some Kerbalis titanicus societies, which some Tyrannopuses have preyed upon. Every creature seems to have, or have had in some cases, some wariness towards the animal. In fact, the only three animals that can make the Tyrannopus afraid is an adult bull Titanocephalus, a Giraphant Gigantothere, and a larger Tyrannopus.
