Resembling a Triceratops, this giant herbivorous dinosaur has a massive frill on its head, two long and sharp brow horns, and a small horn on its nose. Its eyes are positioned near the nose area, and its body features brown and ochre skin with dark mottled patterns. It is a quadruped with a massive build, its hip height far exceeding that of an adult male.

An omnivore resembling a Parasaurolophus, featuring a large bony crest and powerful toothed jaws. It walks on short, thick hind legs like a ground sloth and possesses powerful forelimbs capable of grasping objects. Its back is dark brown and reddish-toned, while its belly is light beige leathery skin, using a long tail for balance. While it usually eats grass, it has a ferocious habit of preying on humans.

It has the appearance of a theropod dinosaur with a giant, ornate yellow frill around its neck.

Its eyes are round and wide, giving a glaring impression. It is diminutive, with the neck and upper body being abnormally thin and gaunt compared to the head size, showing contoured ridges as if the spine and ribs are exposed through thin skin. Unlike the upper body, the hind legs are thick and muscular. A long, flexible tail extends far behind to maintain balance. The overall body shape is similar to a bipedal theropod dinosaur. It has a rough, deeply wrinkled texture like parched leather or reptilian skin, creating a sinister atmosphere. Ankles are bent backward. Carnivorous.

Possesses a thin, elongated neck and a spine that can twist like a snake. The snout is long and pointed, and the limbs are extremely thin and delicate.

Wings extending from the position of the front flippers have a bat-like structure with thin membranes between finger bones.

The rear part of the torso is flexible and long like a ray's tail, with ribs and vertebrae gauntly exposed along the back line, giving a skeletal feel. An extremely thin body that looks like only bone and skin remain with almost no flesh or muscle. Two heads that appear connected vertically or horizontally on a single torso, resembling a crocodile.

The skin is dark-toned with a rough, tough leathery texture. Abnormal Forelimbs: The most distinctive part, completely different from human hands or typical dinosaur paws. The fingers and claws are thin and long like tree branches, splitting grotesquely in all directions, reminiscent of spider legs or sharp rakes. Lower Body and Tail: Has very large, thick muscular hind legs compared to the upper body, showing powerful support. They are structured with reverse joints suitable for sprinting at high speeds or leaping. Tail: Extends long and thick behind the torso, tapering toward the end.
