Doscasaurus is a species of animal that live in Fiore.
The Doscasaurus is an enormous, carnivorous dinorsoure-like creature covered in scales and walking on its rear legs, with its forelegs being smaller in comparison, much like a real t-rex. It possesses a prominent, dark round section topping the upper front part of its head which it uses to headbutt preys to eat, something which it's proud of. It eats the meat of animals it crushes with its head. They are a rare species that live deep in forested or dry and rocky areas.
- Size: The Doscasaurus' main threat is its size, it can take a tough hit without even noticing and dish out even more without even trying.
