The only thing a catastrophic fraggon has to fear is another catastrophic fraggon.
Dracobufo Rex is the largest land-dwelling carnivore the world of Amphiterra has ever seen.
The catastrophic fraggon’s temperament and dietary requirements necessitate an incredible territory size, roughly 300-50 square miles per individual, and a tremendous amount of the fraggon’s energy goes into defending that territory from members of its own species. A clash between fraggons is like no sight on Earth. The encounters begins, and often ends, with posturing and threat. Throat, nose and back sacs fill with air, flushing them with color and size. Whisker papillae extend with vibrancy, the tail too turns a shocking red. As if this weren’t enough, the sound is deafening, a high pitched raspy wailing at odds with the creature's’ size. The two combatants compete to see who is louder, bigger and scarier. If one fraggon doesn’t back down, the two clash with tusks and crest, and the injuries at this stage can easily be fatal. The fraggon’s mating ritual is almost identical to competition for land
The clavical ring that began overdeveloping in the Greater moistboy acts as the lynchpin to the fraggon’s massive bulk. This fused, hypertrophied ring carries most of the creature’s weight, and acts as the center of gravity. The massive sternum can even be used in combat and predation, to bash and pin down a foe.
The catastrophic fraggon’s reign is to be amazing, but short. Like the tyrannosaurus of our timeline, its low reproductive rate and population, as well a huge caloric needs, make it ill-equipped to survive when an ice age strikes roughly 2.75 million years ago. The Dracobufidae are instead to be survived by the fraggon’s cousin, the arctic fraggon.
