"Tyrantrum are large, dinosaurian Pokemon, closely resembling theropods like Tyrannosaurus. They are predominantly brick red in coloration, with scaly patterns on their skin and scattered orange highlights on some of the scales and ridges. The underbelly is gray with white borders, and they have a long tail with two orange spikes near the tip. Their small forelimbs have only two black clawed digits, but they have powerful hind legs with three sharp, black talons. Plated, armor like ridges are found on the front of the legs and down the back and tail. Spiky, white "fluff", similar to the primitive feathers on many dinosaurs, extends into a cape-like fringe around the neck. Additional feathering forms a prominent beard on the lower jaw, which is otherwise gray in coloration. Their heads are proportionally large, with a ridged snout and powerful jaws. The lower jaw is lined with razor-sharp teeth, and the upper jaw features a number of tooth-like projections which are also highlighted orange. Their eyes appear to have black sclerae with white irises. An orange, five-pointed crest extends from the snout above the eyes and point backwards, giving it the appearance of wearing a crown."
