Doscadon

Doscasaurus (ドスカドン, Dosukadon) is a species of animal that resides on Tenrou Island.

Description
The Doscasaurus is an enormous, carnivorous dinosaur-like creature covered in scales and walking on its rear legs, with its forelegs being smaller in comparison, much like a real tyrannosaurus 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.

Habitat
Doscasaurus inhabit the northwestern part of Tenrou Island, whether they inhabit Tenrou Island alone, however, is unknown.
